Cruise Control In Cars Explained (And How To Safely Use It)

cncl meaning cruise control

Have you ever wished you could set your car's speed and just sit back and relax while driving on a long stretch of highway? If that's the case, then cruise control is just the ticket you've been searching for—and the good news is, it's a standard feature in most cars these days!

Cruise control is a handy feature for drivers that allows you to maintain a constant speed without having to keep your foot on the gas pedal. In this post, we'll explore how cruise control works, its benefits, and how to use it safely to make your driving experience more comfortable.

Understanding Cruise Control

Cruise control, also known as speed control, is an electronic system that allows you to maintain a specific speed without manually controlling the accelerator pedal. The system uses sensors and electronic components to control the throttle and keep your car moving at a desired speed. First introduced in the late 1950s, cruise control has since become a standard feature in most modern vehicles you see on the road today.

How Does It Work?

At its core, cruise control involves a series of sensors that monitor the vehicle's speed and a control unit that regulates the throttle. When the driver sets the cruise control to a specific speed, the system adjusts the throttle to maintain that speed. If the car begins to slow down because of an incline (e.g. going up a hill), the system will open the throttle to accelerate. Conversely, if the car starts to speed up due to a declin (e.g. going downhill), the system will close the throttle to decelerate.

Modern cruise control systems also come with additional features like adaptive cruise control (ACC), which uses radar or cameras to detect vehicles ahead and automatically adjusts the speed to maintain a safe following distance (more on this BELOW).

The History of Cruise Control

The invention of cruise control can be traced back to the late 1940s and early 1950s, when engineer Ralph Teetor developed the first-speed control system. This innovative feature was designed to help drivers maintain a steady speed, reduce fatigue while driving, and improve fuel efficiency. Over the years, cruise control technology has undergone significant advancements, leading to the development of sophisticated systems like adaptive cruise control.

Types of Cruise Control Systems

Today, drivers can choose from a range of cruise control systems, each with its own unique features and functionalities.

Conventional Cruise Control

Conventional cruise control is like your old reliable friend. It's pretty basic and doesn't have any fancy bells and whistles. You just set the speed you want, and it'll keep your car cruising along at that speed, no problem. It's perfect for those long drives on open highways, but it doesn’t automatically react to other cars on the road.

So, if the car in front of you slows down, you'll need to step in and adjust your speed manually. This trusty system comes standard on most cars and is great for saving some fuel on those long road trips .

Adaptive Cruise Control (ACC)

Now, if conventional cruise control is your old reliable friend, then Adaptive Cruise Control (ACC) is like that friend's tech-savvy younger cousin. ACC isn't just maintaining your set speed, it's also keeping an eye on the car in front of you. If that car slows down, ACC slows your car down to keep a safe distance .

It's like having an extra set of eyes on the road, making highway driving a breeze. Plus, some ACC systems can even handle stop-and-go traffic, bringing your car to a full stop and then picking up speed again when traffic gets moving.

Predictive Cruise Control

Predictive Cruise Control is like the fortune teller of cruise control systems. It uses GPS and map data to see into the future and predict what's coming up on the road, like hills or curves, and adjusts your speed accordingly. This means you get a smoother ride and better fuel efficiency, but it all depends on the quality of the GPS and map data. If that's a bit out of date, your fortune-telling cruise control might not be so accurate. It's usually found in more high-end vehicles where top-notch fuel efficiency is a focus for the engineers.

Cooperative Adaptive Cruise Control (CACC)

And then we have Cooperative Adaptive Cruise Control, or CACC. This is like the team player of cruise control systems. It allows cars to talk to each other, coordinating their speeds to maintain a safe distance. It's like having a well-coordinated team of cars all working together to make the traffic flow smoother and reduce congestion. Picture it like a synchronized dance on the highway, where every car knows its place and keeps the right distance. This tech is still pretty new, but it's got a lot of potential. Imagine a future where traffic jams could be a thing of the past.

Remember, these systems are here to make your drive smoother and safer, but they're not a replacement for your attention. No matter how fancy your cruise control is, these systems can be greatly influenced by external conditions like weather and traffic, and they should always be used as aids, not replacements, for attentive driving.

Common Cruise Control Symbols and Indicators

Understanding the various symbols and indicators associated with cruise control is important for safe and effective usage. These symbols typically appear on the dashboard (or on the side of the steering wheel) and may include a speedometer icon, "SET," "RES" (resume), and "CANCEL". Be sure to consult your vehicle's owner's manual for specific details and explanations of these symbols.

Benefits of Using Cruise Control

Cruise control offers several benefits to drivers, especially during long road trips or highway driving.

Fuel Efficiency

One of the main advantages of using cruise control is improved fuel efficiency. By maintaining a constant speed, cruise control helps reduce fuel consumption, leading to better gas mileage. Rapid acceleration and deceleration, on the other hand, can lead to increased fuel consumption.

Comfort and Convenience

Cruise control allows drivers to take their foot off the accelerator pedal, reducing fatigue and improving comfort during long drives. It also helps drivers avoid unintentionally exceeding the speed limit by setting a maximum speed.

When used correctly, cruise control can contribute to safer driving. By maintaining a steady speed, it reduces the likelihood of erratic driving behavior and potential accidents. However, it is important to note that cruise control shouldn't be used in certain conditions, such as heavy traffic or slippery roads .

Troubleshooting Common Cruise Control Issues

Occasionally, you may encounter issues with your cruise control systems. Common problems include cruise control not engaging or disengaging unexpectedly. Possible causes may include a faulty brake light switch, malfunctioning sensors, or issues with the control module. If you experience any problems with your cruise control, it's best to have a qualified technician diagnose and repair the issue for you.

Cruise Control and Road Etiquette

Practicing proper road etiquette while using cruise control is essential for a safe and pleasant driving experience. Here are some tips on how to use cruise control courteously:

  • Avoid using cruise control in heavy or congested traffic, as it may hinder your ability to react quickly to changing conditions.
  • Be mindful of other drivers when setting your speed. Avoid setting a speed that's significantly slower or faster than the flow of traffic.
  • If you are in the passing lane and using cruise control, be sure to adjust your speed or temporarily disengage the system to allow faster-moving vehicles to pass.
  • Always signal your intentions, such as lane changes or exiting the highway, even when using cruise control.

The Future of Cruise Control Technology

Cruise control technology plays a vital role in the development of autonomous vehicles, or self-driving cars . In autonomous vehicles, cruise control systems work together with other advanced driver assistance systems (ADAS) to enable the vehicle to operate without direct driver input. These systems include lane-keeping assist, automatic emergency braking, and collision avoidance systems.

As autonomous vehicles become more sophisticated, cruise control technology is evolving to support higher levels of automation. For example, some autonomous vehicles are equipped with advanced cruise control systems that can navigate complex traffic scenarios, merge onto highways, and even change lanes autonomously.

While fully autonomous vehicles are still in the developmental stages, the integration of cruise control technology is a big step toward creating safer and more efficient transportation systems.

As automotive tech continues to advance, cruise control systems are becoming more intelligent and capable. Here are some potential developments we can expect to see in the future of cruise control technology:

  • Integration of artificial intelligence (AI) to improve decision-making and responsiveness in adaptive cruise control systems.
  • Enhanced connectivity and vehicle-to-vehicle (V2V) communication, enabling cars to share information about traffic conditions and coordinate their speeds for smoother traffic flow.
  • Greater customization and personalization options, allowing drivers to set preferences for cruise control behavior, such as following distance and speed adjustments.

Overall, the future of cruise control technology holds promise for creating a more seamless and enjoyable driving experience, with a focus on safety, comfort, and sustainability.

Debunking Myths About Cruise Control

Let's address and debunk some common misconceptions about cruise control:

Myth : Cruise control can be used as a substitute for driver attention.

Fact : Cruise control is a driver assistance feature, not a replacement for attentive driving. Drivers should always remain alert and ready to take control when necessary.

Myth : Cruise control increases the risk of accidents.

Fact : When used appropriately, cruise control can contribute to safer driving by maintaining a steady speed and reducing erratic driving behavior.

Cruise control is a valuable feature that can enhance your driving experience by providing comfort, convenience, and fuel efficiency. Remember to use it safely and appropriately based on driving conditions, and always stay attentive while on the road.

Although everybody likes steering wheel controls because they are friendly and close to where they are needed, Ford overdoes the number of controls when they present them in this fashion. If you want to learn about their steering wheel controls for the 2012 Ford Fusion, this article will describe them for you.

Preparing Yourself to Use

  • Others will need to be read when you are not driving, yet used when you are driving in normal traffic patterns.

Using Cruise/Speed Control

  • 1 Learn where these controls are. Cruise control buttons are found on a panel of buttons in the area between the 9 and 6 positions of the steering wheel. They aren't found on a stick, like on some cars from 2012.
  • Once it is on, you'll see an amber light illuminate on your dashboard near your gas status meter stick near the driving gear information section.
  • 3 Learn how to set the speed. The speed can be set with the toggle switch buttons on the top row of the cruise control buttons. Accelerate to the speed you'd like to cruise at, and press the + sign, and take your foot off the gas pedal. Once it is on, the green set light will appear on your dashboard - on the side of the gas status meter stick, near the driving gear information section.
  • 4 Increase your set speed. Either hold the Set + button until you've accelerated to your wanted speed or press and release the Set + a given number of times to increase the speed in 1 mph or 2 km/h increments - or utilize your accelerator pedal and press + to set the new speed - over-writing the original set speed.
  • 5 Decrease your speed in a similar fashion. Press and hold the - Set button to decrease the speed and release when it is set or press the - Set button to decrease the speed in 1mph/2kmph increments or utilize your brake pedal until the speed reached is ample.
  • If your speed decreases by more than 10 mph on an uphill, your cruise control will disengage - cancel.
  • 7 Resume a set speed. If you have a speed set in the cruise control system and can return to that speed safely, press the RSM button - which is the CNCL/RSM buttons' second task.

Using Car Settings

  • The options your car will have will depend on what options your specific car has - also some have more options than others. Some have blind-spot monitoring, while others have CROSS TRAK assist, and others may have additional trouble actions that need to be looked into to be driven with safety in mind and to control what's seen.
  • Press it once, press RESET to have it cycle to test and display the status of each different vehicle system. Trouble faults are displayed in your message center inside your instrument cluster on your dashboard.
  • 2 Learn about a variety of information from the INFO button. You can find your INFO button on the third row on the left side. Tap it to display your trip odometers (trip a and trip b), your gas tanks approximated miles to E (displayed as Miles to E), fuel economy rating (as AVG MPG), MPG is a graphical view of your MPG over the trip over a set period of time or chronometer of your driving time - when you utilize your RESET button to reset the information periodically. But if you tap it again, it'll cycle your information to a blank screen.

Using Media Controls (if equipped)

  • 1 Recognize your media control buttons - if supplied with them. Each type of system will be set up a little differently. If your car just has a radio, you'll have different keys than ones that have nav system buttons, and ultimately a different one than ones with Ford Sync hands-free controls.
  • 2 Learn about your volume controls. For those with just radios and those with navigation systems, your volume controls come on two separate buttons - controlled from the bottom right in your steering wheel. Volume up will be on the top row, volume down will be on the second row. But if you have Ford Sync, volume down is listed as - VOL, and VOL + is two separate buttons in the top row together.
  • Tapping the left and right buttons will allow you to skip through favorited or memory buttons while tapping and holding (then releasing) will allow you to have your radio scan the airwaves for the next available radio station. Do this as many times as necessary to find the right station for you.
  • When using Seek with CDs, seeking allows you to move between tracks (back or forward or up or down a folder level with MP3-formatted discs).
  • 4 Learn about the Media button. The media button cycles through different modes for your radio. These include the radio (AM1, AM2, AM3 and FM1, FM2, FM3 in separate band selections), CD, Sirius Satellite (if available), and navigation system options. The Media button can be found as the bottom button (in a car with just a radio), as the bottom right button in a car with just a navigation system), or as the third-row right side button in one with SYNC or sync with Navigation).
  • 5 Get access to voice command mode. Also on the row to the left of MEDIA is your voice command button. The button on the left of the third row that looks like a bunch of waves protruding from the mouth is your voice command enabling button. Press it once to start a voice command session, and wait for the tones. Press it again to stop a voice command session.
  • 6 Learn about your calling button (for systems with Sync and hands-free calling). To activate a call, press it once to either start a new call or pick up on a call that's calling you. End a call by pressing and holding it or exit a phone mode. The call button will look like an upside-down landline phone with a ray pointing downward and can be found on the fourth line on the left side of one with Ford Sync with and without navigation.

How to Use Cruise Control Safely

Everything you need to know for safe, stress-free driving with your car's cruise-control system.

clock, font, icon, circle, illustration, logo, stopwatch, home accessories, symbol, graphic design,

Its Job Is to Maintain Speed

Cruise control's primary function is to maintain the speed of your choosing, relieving you of needing to keep your foot on the throttle. Virtually all cars on the road today rely on an electronic control module—a computer—to monitor the vehicle's speed and to readjust it as needed to hold the speed you've chosen regardless of the road's gradient.

 

Know the Controls

You operate cruise control by either a stalk on the steering column or several buttons on the steering wheel. These include an on-off switch; a "set" button to select the speed you want the car to maintain; and buttons or switches marked "+" and "—" that increase or decrease the speed after it has been set, often in 1-mph increments. A "cancel" button disengages the cruise-control system without shutting it off entirely, allowing the car to coast. (Cars with stalk-operated cruise control have a "cancel" position that you move the stalk to in order to disengage the system.) A "resume" function or button brings the car back to its previously set speed. Braking or depressing the clutch at any time will also cancel cruise control. Should you need to make a quick pass, you can always override the preset speed by simply pressing down further on the gas pedal.

Adaptive Cruise's Added Features

Many newer cars offer what's known as adaptive cruise control, sometimes also called active cruise. It works in the same way as conventional cruise systems and additionally relies on front-mounted radar , cameras, or sensors to detect the presence of vehicles directly ahead in your lane. This enables adaptive cruise-control systems to maintain a set distance from the vehicle in front no matter how it varies its speed.

Adaptive systems allow you to adjust how closely your vehicle follows the one ahead but are programmed so that they always maintain at least a safe minimum following distance. Some of these systems also have the ability to brake and even come to a complete stop in city traffic and, depending on the vehicle, automatically accelerate without the driver pressing the gas pedal when traffic starts to move again.

Semi-Autonomous Cruise Control

Finally, the newest, most advanced cruise control systems, such as such as Nissan ProPilot Assist, Subaru EyeSight, and Audi Traffic Jam Assist, are semi-automated driving assistants that combine adaptive cruise control with lane-keeping assist, which self-steers the car gently to keep it in lane if you let it wander out—although you can only take your hands off the wheel for a few seconds before the system sounds alarms and then shuts off.

.css-1rvrtxn{font-family:Gliko,Gliko-fallback,Gliko-roboto,Gliko-local,Georgia,Times,Serif;font-size:1.625rem;line-height:1.2;margin:0rem;-webkit-text-decoration:underline;text-decoration:underline;text-decoration-color:#DBCA8B;text-decoration-thickness:0.25rem;}@media(max-width: 48rem){.css-1rvrtxn{font-size:2.25rem;line-height:1.1;}}@media(min-width: 48rem){.css-1rvrtxn{font-size:2.625rem;line-height:1.1;}}@media(min-width: 64rem){.css-1rvrtxn{font-size:3rem;line-height:1.1;}}.css-1rvrtxn b,.css-1rvrtxn strong{font-family:inherit;font-weight:bold;}.css-1rvrtxn em,.css-1rvrtxn i{font-style:italic;font-family:inherit;} No matter what type of cruise control your car has, the rules for using it safely are the same.

Most of these systems also can autonomously negotiate only the most gentle curves on the interstate. Some semi-autonomous systems, such as those from Tesla and Mercedes-Benz , can do more, including steering the car into the adjacent lane while keeping enough distance from other cars.

Follow These Safety Rules

No matter which type of cruise control your car has, the guidelines for using it effectively and safely are the same:

  • Always remain alert and aware of other traffic, and be ready to take control and brake or steer around obstacles, inattentive drivers, or emergency situations.
  • Think of even the most advanced adaptive and semi-autonomous cruise control systems as "dumb." They are programmed by humans and may react unpredictably in certain, unforeseen conditions. (See previous point: "remain alert.") Rain, snow, and fog can obscure radar signals and confuse cameras or sensors, sometimes disabling adaptive cruise control entirely. As with conventional cruise control, with an advanced cruise system you must always be prepared to take full control at a moment's notice.
  • Cruise control is still best suited for use on highways and in light traffic. If your vehicle has conventional (not adaptive) cruise control, be sure to leave adequate spacing between your car and those ahead, and be prepared to disengage the system by braking or tapping "cancel" as you creep up on other vehicles or get into heavy traffic.
  • Do not use cruise control in slippery conditions, including snowy or icy roads or rain-soaked roads awash in deep puddles. Most cruise systems will attempt to maintain your speed until you intervene, and on slippery roads that could cause you to momentarily lose traction, upsetting the car and potentially precipitating an accident.

Treat cruise control as a simple labor-saving convenience, however—but one that must be monitored—and you'll enjoy many miles of comfortable, stress-free travel.

What is Cruise Control and How Does it Function in a Car?

What is Cruise Control and How Does it Function in a Car?

A Quick Overview

Driving on long stretches of highway can be tiring, especially when trying to maintain a constant speed. Cruise control alleviates this by allowing drivers to set and maintain a desired speed without continuous use of the accelerator pedal. Understanding how cruise control functions can help drivers make the most of this convenient feature.

What is Cruise Control?

Cruise control is an automotive feature that enables drivers to set a desired speed for their vehicle. Once activated, the cruise control system maintains the set speed without the need for constant pedal input. It helps drivers maintain a steady pace on long trips, providing convenience and reducing the likelihood of unintentional speed fluctuations.

How Does Cruise Control Function?

Cruise control systems may vary slightly among different vehicle models, but they generally function using the following components and controls:

1. Set Button

To activate cruise control, the driver typically presses a “Set” button or engages a switch on the steering wheel or dashboard. This action captures the current speed of the vehicle and sets it as the target speed for the cruise control system to maintain.

2. Speed Control

Once the cruise control system is activated, the driver can adjust the speed using speed control buttons. These buttons allow the driver to increase or decrease the set speed in small increments. By pressing the appropriate button, the driver can fine-tune the desired speed for their comfort and road conditions.

3. Resume Button

The “Resume” button, also known as the “Accel” button, allows the driver to restore the previously set speed after it has been canceled or temporarily interrupted. When the driver presses the “Resume” button, the cruise control system accelerates the vehicle to the previously set speed.

4. Cancel Button

The “Cancel” button, often marked with the symbol “CRUISE” or “OFF,” deactivates the cruise control system. Pressing this button disengages the system and allows the driver to regain full control over acceleration and braking. It is important to note that the brake pedal can also automatically deactivate cruise control when pressed.

Advantages of Cruise Control

Cruise control offers several advantages to drivers:

  • Reduced Driver Fatigue: Cruise control allows drivers to maintain a steady speed without continuously pressing the accelerator pedal, reducing fatigue on long drives.
  • Improved Fuel Efficiency: By maintaining a consistent speed, cruise control can help optimize fuel efficiency by reducing unnecessary acceleration and deceleration.
  • Avoiding Speeding: Cruise control helps drivers adhere to speed limits by maintaining a set speed, preventing unintentional speeding due to variations in foot pressure on the accelerator pedal.

Limitations of Cruise Control

While cruise control provides convenience, there are limitations to consider:

  • Traffic and Safety: Cruise control should be used only in appropriate situations. It is important to remain vigilant and be ready to take control of the vehicle when necessary, such as in heavy traffic or hazardous road conditions.
  • Hilly Terrain: Cruise control may struggle to maintain a constant speed on hilly terrain, as it cannot anticipate changes in elevation. In such situations, the driver may need to manually intervene and adjust the speed accordingly.

cncl meaning cruise control

In the past couple of decades, increasingly more functions have been migrating from their traditional positions on the console or dashboard onto the steering wheel. Radio controls, cruise control operation and several others have been integrated into steering wheel technology.

These multi-function steering wheels, as some companies call them, improve driving safety by putting the most commonly used controls in one of the most convenient places possible -- right at the driver's fingertips. A driver's eyes and hands are extremely important tools for driving. Keeping your eyes on the road and hands on the wheel can increase auto safety for everyone in your own car and those around you, too.

It's not surprising, then, to learn that the most commonly used controls have made their way onto the steering wheel

  • Cruise control: including a buttons for setting and changing speed
  • Sound system controls: usually for adjusting volume or scanning preset radio stations
  • Phone answering: often with Bluetooth or similar wireless connections

Some cars go even further in using the steering wheel to increase car safety by adding controls for air conditioning, a steering wheel heater, or even access to an on-board computer like the SmartGauge found in the 2010 Ford Fusion .

 Most often, these controls are installed at the factory and come with the car when it's new, either as standard equipment or as optional upgrades. Some companies, like Pioneer, even sell steering-wheel-mounted remotes for their aftermarket stereo systems -- again, to improve driving safety.

With all these gadgets installed on the steering wheel, however, are the features and functions any easier to operate or does it actually make it more difficult for the driver to properly adjust everything?

Using Steering Wheel Controls

Advances in steering wheel controls.

Using steering wheel controls as a method to up the driving safety quotient is about as easy as it comes. Manufacturers simply place the steering wheel buttons in positions where they're easily reached by one thumb or the other without the driver having to remove his or her hands from the wheel. As Jim Morrison, that paragon of rock-and-roll safety, sang, "Keep your eyes on the road, your hands upon the wheel."

Even in the best-designed cars, having things like radio controls in the center console between the two front seats requires the driver to take his or her eyes off the road for a second, or two -- or even more, sometimes -- to locate the volume knob or station preset buttons. Once the driver finds the button or knob they're looking for, one hand has to leave the steering wheel to change the radio station or crank up the volume.

By using steering wheel buttons, all those extra motions can be avoided. At first, the driver may need to glance down to remember which button moves the radio station to the next preset or which toggle switch adjusts the volume. But after using these steering wheel controls for even a few trips, the driver will become accustomed to the placement. With a little practice, your thumbs will switch from your spouse's favorite station to yours and turn up the tunes without ever taking your eyes from the road or your hands from the steering wheel.

Phones that are able to be used with wireless systems like Bluetooth further up the auto safety ante. Many states restrict in-car mobile phone use to hands-free devices. A steering wheel with built-in buttons for sending and receiving phone calls makes the process easier and a lot safer.

But what's beyond these basic controls? Actually, quite a bit. Let's take a look on the next page.

cncl meaning cruise control

As electronics have become smaller, cheaper, and more popular in passenger vehicles, advances in steering wheel buttons have taken driving safety even further, too.

First, the issue of the lowered cost of the necessary electronics has made steering wheel controls more common. This, by itself, improves auto safety across the board -- for everyone on the road. If more drivers are able to pay extra attention to driving and less to reaching for the radio or fumbling for their phone, they have a better chance of reacting to split-second situations that could otherwise lead to accidents.

Cruise control has been available as a steering wheel button operation for some time, but advances in the cruise control system itself make this a high-tech piece of auto safety. In some cars, when cruise control has been set (using a button on the steering wheel, of course), sensors on the front bumper adjust the speed of the car to provide a cushion of time and or distance between your car and the one in front of you on the highway. It's commonly called adaptive cruise control, and although not every new car comes equipped with this advanced feature (not yet, anyway), most steering wheel-mounted cruise control functions include up and down buttons for adjusting the speed of your car manually.

The new Ford Fusion Hybrid is an example of a very advanced set of steering wheel controls that interface with its SmartGauge on-board computer. The dashboard in front of the driver consists of two LCD displays with a traditional speedometer in the center. Depending on the amount and type of information the driver wants to see, he or she can use the dedicated steering wheel controls to find power usage, battery life, fuel economy and more. This is in addition to the Microsoft voice-activated SYNC system, which can also be accessed from the steering wheel. So it's getting easier and easier to follow Jim Morrison's advice to "Keep your eyes on the road, your hands upon the wheel."

What is Cruise Control

Cruise Control Explained – All You Need to Know

Zutobi

Cruise control has come a long way since first invented and patented by Ralph Teetor in 1950, who originally named it the “Speedostat”. Chrysler Corporation was the first manufacturer to offer the groundbreaking mechanism as an option on several of its luxury vehicle models nine years later. Today, cruise control is rapidly becoming the standard on all new vehicles, providing drivers with increased convenience on their daily drive.

As you’re learning how to operate a vehicle , understanding cruise control will help increase your comfort behind the wheel and knowledge of driving.

What is Cruise Control?

Cruise control is an electronic device within your vehicle that controls the speed of your vehicle. It allows the driver to maintain a constant speed of 25 mph without holding their foot on the accelerator. Although the feature has been around for 70 years, automotive manufacturers continue to improve upon the technology to provide drivers with increased comfort, luxury, and convenience whenever they’re behind the wheel.

cars driving on a freeway with little traffic

Different Types of Cruise Control

There are 3 types of cruise control systems.

  • Speed Limiter
  • Adaptive Cruise Control
  • Semi-autonomous Cruise Control

What is a Speed Limiter?

A speed limiter will limit how fast the driver can accelerate behind the wheel. All modern vehicles contain a standard speed limiter capping speed between 120 mph and 180 mph depending to protect the vehicle’s engine and discourage reckless driving. However, an additional limiter can be added as an option in many European-made cars, as well as Tesla, Ford, and Nissan. Drivers are still required to keep their foot on the pedal to keep their vehicle in motion, but will not be able to accelerate past a predefined speed limit.

What is Adaptive Cruise Control?

Adaptive cruise c ontrol uses sensors around the vehicle’s exterior to maintain speed while keeping a safe following distance from the car ahead. The system will slow you down and speed you up as the flow of traffic fluctuates throughout your commute, removing a lot of the stress from daily driving. However, adaptive cruise control may not work well in bad weather or protect you from sudden movements, so you will want to always keep your full attention on the road.

What is Semi-autonomous Cruise Control?

Luxury automakers such as Tesla and Audi are implementing the newest rendition of cruise control on their latest vehicle models – Semi-autonomous Cruise Control. It works largely the same as adaptive cruise control, but assists drivers with lane guidance and steering. There are several variations of semi-autonomous cruise control that include additional convenience features for the driver.

How to Use Cruise Control – 6 Step Guide

These are the steps to using cruise control effectively.

  • Observe weather conditions
  • Build speed
  • Engage cruise control
  • Set cruise control
  • Watch the road and steer
  • Brake to disengage

1 – Observe weather conditions

As mentioned, cruise control may become inconsistent in rainy, snowy, or otherwise hazardous conditions. If you must drive in this situation, it may be a better idea to do so manually. Cruise control works best on a clear day with constant traffic flow.

2 – Build speed

Accelerate to your desired speed as you prepare to activate cruise control. US highways have posted speed limits between 55 mph and 75 mph. Do not attempt to set cruise control when you are traveling over the speed limit.

3 – Engage cruise control

Once you’ve reached your desired speed, engage the cruise control. This step will vary widely based on your vehicle make and model, however, many cruise control settings are accessible from the steering wheel controls. Check your owner’s manual for further information.

4 – Set cruise control

After turning on cruise control, you’ll need to set your desired speed. Many systems set the cruise control at the current speed, while others require you to manually set one. You can increase and decrease this speed as needed without interrupting the mechanism.

5 – Watch the road and steer

Watching the road is essential when cruise control is engaged. Cruise control is not a substitute for a human driver and will require supervision at every step. If you are using a semi-autonomous system, you will not need to steer but will need to keep at least one hand on the wheel for safety measures.

6 – Brake to disengage

When cruise control is no longer needed, or you need to quickly make a maneuver, simply apply pressure to the brakes to disengage the system. Once deactivated, you will be in full control of your vehicle once again.

When NOT to Use Cruise Control

While cruise control is a convenient feature for modern drivers, it is not perfect for all circumstances. In fact, utilizing the system can be quite dangerous if you’re not careful. Be sure not to use cruise control under these conditions.

Heavy Traffic

Heavy, or stop-and-go traffic is not ideal for safely using cruise control. When engaging cruise control on the highway, ensure your lane is clear and there are no vehicles stopping ahead.

highway with heavy traffic

Wet or Icy Conditions

You need to be driving slowly while on wet and icy roads. While cruise control keeps a constant, predetermined speed, it takes away a lot of the manual control needed to stay safe when it’s raining or snowing.

City Driving

While driving through the city, you’ll face a number of stop lights and stop signs that will require manual braking. This action will automatically disengage cruise control.

Winding Roads

Winding roads require more attention than straight, flat streets. Cruise control systems, even adaptable cruise control, may not always detect these streets correctly, causing accidents.

Fatigued Driving

Driving while fatigued is never a good idea, but even less so while using cruise control. Utilizing the system may add to your fatigue, as you give your vehicle more control of the journey. If you’re even the least bit tired, you should never turn on cruise control.

As you can see, cruise control is a great way to relieve much of the stress that comes with everyday driving. The constant rate of speed can also drastically improve fuel efficiency for longer drivers. Cruise control has had a positive impact on the driving industry for 70 years and shows no signs of disappearing anytime soon.

When the system is set, cruise control will maintain a steady speed for your vehicle

Article content

Your vehicle’s cruise control system unlocks numerous benefits at the touch of a button — but according to web search data, drivers still have plenty of questions about what it is, what it does, and how it works.

What is Cruise Control? A Comprehensive Guide Back to video

Below, we’ll answer some of the most popular Internet search questions about cruise control, so you can make the best use of this important system.

What is Cruise Control?

With cruise control, your vehicle will maintain a steady speed when the system is set.

What is adaptive cruise control?

With adaptive cruise control, the vehicle will also automatically slow down and speed up to maintain a safe position in traffic.

How does cruise control work?

Cruise control work with a manual transmission just the same way it does with an automatic.  Drivers set their cruising speed with a button press, and the system works the throttle automatically to maintain the desired cruising speed as evenly as possible. In some vehicles with a manual transmission, pressing the clutch pedal to shift gears turns the cruise control off, requiring an additional button press to reengage it after a gear change.

In other cars with a manual transmission, pressing the clutch pedal simply pauses the cruise control system a moment, allowing drivers to complete their gearshift. When they’ve released the clutch, the cruise control picks up where it left off — no additional button press required.

Is cruise control more fuel efficient?

Yes.  Increasing your vehicle’s speed uses fuel. While cruising, even a highly competent driver who isn’t using cruise control will tend to slow down and speed up in a repeated cycle, possibly several times per minute. Though fluctuations in speed may be slight, they do cause your engine to use more fuel than required. Point is, the more time you spend at a steady speed, the less fuel your engine needs.

For most drivers, using cruise control on the highway at 80 km/h can reduce fuel consumption by about 20 per cent. For drivers who find difficulty in maintaining a steady speed and frequently experience big fluctuations, using cruise control can cut fuel use by over 40 per cent.

Depending on what you drive and how fast you drive it, using cruise control could save you between $4 and $20 per hour — based on information from Natural Resources Canada that shows most drivers who don’t use cruise control on the highway will tend to experience a 10 km/h speed fluctuation about three times per minute.

Drivers who have the most difficulty managing their cruising speed could be using 60 per cent more fuel than they need to.

Is cruise control bad for your transmission?

No.  Your vehicle’s engine, transmission and other components are designed to work hand-in-hand with its cruise control system and are extensively tested and integrated with one another for trouble-free performance.

Using cruise control also reduces wear and tear on both your engine and transmission by running things more smoothly and steadily, and reducing workload on both components.

Can you add cruise control to a car?

Yes.  Depending on the year, make and model, cruise control may be available for add-on or retrofit. Professional installation is recommended, and you’ll want to talk to a professional about the specific availability of parts and integration for your vehicle.

In many cases with modern cars, it’s generally easier and more cost effective to just opt for a unit equipped with cruise control from the factory. Cruise control is widely available as standard equipment on most modern vehicles.

Can cruise control get stuck?

Yes , but it’s extremely rare. Older cable-based cruise control systems seem more prone to this rare problem, in which the cable can slip or bind, making the throttle stick into position. More modern vehicles with electronic throttle and monitoring systems make this problem even less likely.

If the cruise control on your car fails to disengage when you want to slow down, slip the vehicle into neutral to disconnect drive power from the wheels, pull over, and address the situation.

However, chances are, you’ll never experience this problem.

When should cruise control be used?

Any time you’re trying to drive at a constant speed.  Whether around town at 60 km/h, in a residential area at 40 km/h, or out on the highway at 105 km/h, switching the cruise control on makes for a smoother and more fuel efficient drive that’s easier on your engine and transmission. it can also help you do your part to maintain the steady and efficient flow of traffic.

Most cruise control systems can be engaged at speeds above 30 km/h.

When should cruise control not be used?

Any time you can’t safely drive at a steady speed.  If the road surface is snowy, icy, slushy or very wet, you’ll want to think twice about switching your cruise control on.

In older cars, having your cruise control engaged on a wet or icy road could allow the vehicle to accelerate or experience wheelspin when driven wheels encounter a low-traction surface. Here, the cruise control system maintains throttle pressure, even in situations where it should be released instead. This could lead to a loss of control.

In more modern vehicles, electronic monitoring is used to automatically disengage cruise control when one of the following happens:

  • one or more wheels slip
  • one or more wheels leave the surface of the road after a major bump or dip
  • the wipers are set to the maximum speed setting in heavy rain

Use your judgement. Safely navigating certain slippery or dangerous driving conditions requires careful manual control of your vehicle’s throttle, and in these situations, you’re best to leave the cruise control off.

What causes cruise control to kick off?

If the cruise control in your vehicle suddenly kicks off, a few things may be to blame.

Sometimes, cruise control disengages automatically when the vehicle’s automatic wipers detect heavy rainfall, or when a wheel spins or (briefly) leaves the surface of the road after a big bump or dip. In other situations, there may be a problem with one or more sensors or switches, including the brake pedal switch, throttle position sensor, or one or more wheel speed sensors.

Your modern cruise control system relies on various sensors and switches to do its job properly. As a failsafe, any problem with these sensors can cause the cruise control system to go offline. If you notice this happening regularly, have your vehicle diagnosed by a professional.

Will the cruise control work with an ABS light on?

Probably not.  Your car’s Antilock Braking System works hand-in-hand with your cruise control system, and any fault with the ABS system will typically take your cruise control offline until it’s fixed.

An ABS warning light in your instrument cluster can indicate one of several major problems or malfunctions, so be sure to have a professional investigate as quickly as possible.

Will cruise control apply the brakes?

No, but adaptive cruise control will.  Standard cruise control (simply called cruise control) holds your vehicle’s speed as constant as possible once set. More advanced adaptive cruise control systems use camera or radar-based sensing to determine the traffic situation in front of your vehicle, and can automatically apply the brakes to maintain a pre-set following distance.

With cruise control, drivers need to brake to slow down as they close in on a slower vehicle in traffic. With adaptive cruise control, the system makes these braking inputs automatically, and the vehicle speeds back up to its pre-set cruising speed once traffic clears.

Before you buy, be sure to determine which type of cruise control system is fitted to the car you’re considering.

What is Super Cruise?

Super Cruise is a next-level driver assistance feature available on certain GM vehicles.

With Super Cruise, the vehicle uses special GPS hardware and sensors to accurately compare its position to a 3D map of pre-qualified highways .

On these pre-qualified highways, Super Cruise allows drivers to go hands-free for extended periods as the vehicle automatically maintains its cruising speed, adjusts that speed for changing traffic conditions, and even precisely follows the curves in the road. It can even make hands-free lane changes.

Super Cruise is not an autonomous system, and in order for it to work, drivers need to keep their eyes on the road — there’s even a camera that monitors the position of the driver’s eyes to make sure they’re focused on the road ahead.

Cruise Control Symbol: All You Need to Know

Tim Miller

Seeing a cruise control symbol on your car dashboard and wondering about its meaning.

In this article, I will explain all you need to know about the cruise control system, including the meaning of the cruise control symbol and how to use the system properly.

What Is Cruise Control?

Cruise control is an electronic system that enables you to maintain a constant speed without keeping your foot on the accelerator. 

Cruise control provides convenience and reduces driver fatigue during long trips. Additionally, by maintaining a consistent speed and eliminating unnecessary acceleration and deceleration, the system also helps improve fuel efficiency .

What Does the Cruise Control Symbol Mean?

The cruise control symbol indicates that the cruise control system is engaged and maintains the set speed . The symbol may also change color or blink to indicate different states or potential issues with the system.

Note that the symbol may vary between different car makes and models. Enter your brand in the search box for detailed information about your cruise control system.

How to Use the Cruise Control Effectively

You can activate the system by pressing the cruise control button on the steering wheel. Thus, set the desired speed (using controls on the steering wheel). The system will automatically monitor the speed and adjust the throttle to maintain that speed. Remember to remain attentive and be ready to take manual control even when using cruise control.

You can also deactivate the system by applying the brakes or pressing the cancel or off button on the steering wheel.

Cruise control is best utilized in specific driving conditions, such as on highways or flat roads with low traffic. However, it should not be used in the following situations:

  • Heavy Traffic : In congested traffic conditions, you need full control of your vehicle, including speed adjustments and braking. Cruise control can impede your ability to react quickly to changing traffic conditions.
  • Curvy or Hilly Roads : Cruise control may not be suitable for roads with sharp curves or significant changes in elevation. Manual control allows for better handling and adaptation to the terrain.
  • Slippery or Icy Conditions : Avoid using cruise control on slippery surfaces or in inclement weather, as it may hinder your ability to make immediate adjustments to maintain traction or handle unpredictable road conditions.

What’s Next?

Cruise control is useful for maintaining a steady speed during long drives. By understanding the operation of the system and how to use it effectively, you can enhance your driving experience and safety.

What is cruise control in a car? Meaning and how does it work?

Cruising on the highway can be a lot of fun. However, it demands maintaining a constant speed for a long time. To achieve that, you need to press the accelerator pedal continuously, which can get tiring after a while. That’s when the cruise control feature of your car comes into play. So, what exactly does it do and how does it work? This article explains cruise control in a car and how to use it in different driving conditions. So, without stepping on the ‘brake’ pedal, read on!

Cruise Control in a Car

What is cruise control in a car?

It is a system that accurately maintains the speed set by the driver without any external intervention. It automatically controls the speed of a car and only allows the vehicle to hit a speed set by the driver. It does not allow the car to cross that speed limit. This feature has become common among modern cars. You can even find this feature in the top-spec variants of some of the affordable hatchbacks and sedans.

How does the cruise control system work?

Cruise control in a car replicates the inputs of a driver to control the vehicle’s speed. But instead of pressing the accelerator pedal, it uses a different mechanism to maintain a constant cruising speed.

Initially, the system used a cable to control the accelerator (throttle valve). You can find these mechanisms in older cars. It adjusted the vehicle's speed by engaging the throttle with the help of an actuator that is controlled by a cable. The throttle valve is responsible for the power and speed generated by the engine. So, depending on the speed set by the driver, the system automatically adjusted the throttle position.

But with the advent of technology in the automotive industry, the cruise control system in modern cars entirely relies on electronics. Instead of a cable, the system now communicates with the throttle via various sensors connected to a computer (ECU - Electronic Control Unit). So, when you set a speed, the ECU calculates the throttle position and engages the throttle wirelessly.

The system constantly maintains the speed set by you (driver) irrespective of road conditions. For example, if there’s an incline ahead, cruise control adjusts the throttle accordingly to maintain the same speed.

How to use cruise control?

Before engaging the cruise control in a car, remember that the system is not intended to be used in adverse weather conditions. For example, you may refrain from driving the car at cruising speeds when it’s raining heavily. The low visibility and unpredictable road conditions make it unsafe to drive at such speeds. So, always be mindful of the weather condition and your surroundings before engaging the system.

Here are the steps to use cruise control.

Step 1 - Before activating cruise control, build up speed by accelerating the car. However, do not cross the speed limit of that particular road/highway.

Step 2 - Once your car reaches the desired speed, activate cruise control. Generally, the system activation button will be on the steering wheel. However, locating the exact button when the vehicle is parked is better to avoid any distractions while driving.

Step 3 - Next, you can take your foot off the accelerator pedal. If you have set the cruise control correctly, the car should maintain the cruising speed.

Step 4 - Keep your eyes on the road as it is very easy to get distracted when the car is accelerating automatically.

Step 5 - If you wish to accelerate when the cruise control is engaged, you can press the ‘+’ button on the steering wheel to briefly engage the accelerator pedal.

Step 6 - To decelerate, press the ‘-’ button on the steering wheel. You can also tap on the brake pedal. However, as a safety precaution, almost all cars will deactivate the cruise control as soon as you press the brake pedal.

The buttons to activate cruise control or accelerate/decelerate may vary from one car to another. So, do check the owner’s manual before fiddling around with the system. It’s better if you are familiar with the controls before driving the vehicle, as it will avoid unnecessary distractions.

How to install cruise control in a car?

Can you install cruise control in a car? The answer is both yes and no. You may install an aftermarket kit if it’s an old car that does not rely on electronics to control all the engine-related functions. But installing such a kit becomes almost impossible in modern cars due to the complex electronics.

It is a complex process to install the system in new cars as you have to fiddle with electronics, and it also requires the fitment of hardware. So, it can only be done during the time of car manufacturing. Moreover, if you try installing an aftermarket kit, you may void the warranty offered by the OEM (Original Equipment Manufacturer). On top of that, it is not recommended to go for an aftermarket cruise control kit as it may compromise safety.

Newly launched cars are equipped with cruise control except for a few entry-level models. So, instead of investing in retrofitting a system, it's better and safer to spend that money on buying a car with a built-in system.

Adaptive cruise control

The new technology also allows the system to automatically adjust the car's speed depending on the speed of the vehicle ahead. This feature is known as adaptive cruise control. It ensures that the car maintains a safe distance from the vehicle ahead despite the constant change in speed of the vehicle moving ahead. It is instrumental in highways or during rush hour traffic and reduces driver fatigue.

It is also a level 1 autonomous driving system. The system uses radar sensors to calculate the speed and distance of the car ahead. For instance, if the vehicle in front of you slows down/speeds up, a car with adaptive cruise control will reduce speed/accelerate automatically without any external inputs.

You can find this feature in premium cars. But gradually, it is trickling down to not so expensive cars as well. Adaptive cruise control is a part of an advanced driver assistance system.

Pros and cons of cruise control

Cruise control makes driving easy and convenient, and at the same time, it also takes care of safety. But like every other feature, it has its own set of advantages and disadvantages, which are elaborated in the following section.

Below are some of the pros of the cruise control system.

Reduces driver fatigue: The primary role of cruise control is to maintain a constant speed without you having to step on the accelerator pedal. That means you can rest your right foot and can stay relaxed. It is helpful when you drive long distances on highways where you need to maintain a constant speed for long durations.

Improves fuel economy: When maintaining a constant speed, the engine will not get stressed as it need not change the intensity of operation. To put it in a simple way, when the engine runs at constant RPMs (Revolutions Per Minute) , it consumes less fuel. Hence, when driving long distances on highways, the cruise control system can improve fuel economy.

Helps to drive within the speed limit: You may drive at normal speed on busy urban roads. But when you hit the wide and smooth highways, you may end up crossing the speed limit. You may not even realise that you have crossed the speed limit until you glance at the speedometer. Cruise control can help you in this regard as you can easily set a speed limit and let the system do the work. The system will not allow the car to go over the speed set by you.

Increase/decrease speed with a click of a button: Typically, you use the accelerator and brake pedal to increase/decrease the speed of your car. But when the cruise control is engaged, you can even use the buttons to do the job for you. However, ensure that you are familiar with the functions of the buttons, as it may feel unnatural in the beginning. It is best to practice using the buttons in a safe environment before using them on public roads.

Works well with automatic cars: Cruise control works best with automatic cars as you need not worry about changing gears. The ECU or the onboard computer shifts the gears automatically when there is a change in speed and works well when cruising automatically. It means you only need to focus on steering the vehicle.

As mentioned earlier, cruise control also has some cons, which are listed below.

Limited use on Indian roads: Cruise control is suited for wide and long highways where drivers follow the rules. Although India has some excellent highways, many drivers may disregard rules which creates an unpredictable environment. Also, cattle, dogs and other animals may venture into public roads and make the situation even more tricky. Hence, it may be challenging to cruise at high-speeds.

Hampers reaction time: As mentioned above, the roads in India are unpredictable. You may have to perform emergency braking to avoid any obstacles on the road. When driving with manual controls, your right foot will be on the accelerator pedal, and it is easy to move your foot to step on the brake pedal in an emergency. But, when using cruise control, your right foot will be resting on the floor of the car, and it may take a bit more time to reach the brake pedal. This difference in reaction time may be the difference between you avoiding an obstacle or crashing into it.

Can induce drowsiness: If you use cruise control for long durations, you may end up feeling drowsy. Since the car is accelerating at a constant speed, your alertness level may drop in the long run. Hence, it is recommended that you manually control the vehicle once every 10-15 minutes when using the automatic cruising feature on highways.

Cannot use at night: Cruise control is of no use during night drives as the visibility is poor. Even with well-lit roads, the visibility is not as good as daylight. So, allowing the car to maintain a constant speed may be a safety concern, even on roads that are familiar to you.

It does not work well with manual cars: In a manual car, you have to change gears by yourself. The cruise control will handle the acceleration/deceleration, but you still need to shift the gears manually to maintain the optimum RPM. It can be irritating at times when you need to slow down and accelerate immediately. It may not be a dealbreaker, but it kind of refrains you from experiencing the full potential of the automatic cruising system.

Cruise control vs adaptive cruise control: Key differences

The below table highlights the key differences between cruise control and adaptive cruise control.

What is the difference between cruise control and speed limiter?

Sometimes you may get confused between cruise control and speed limiter as both are related to the car's speed. Refer to the table below to understand the difference between both the systems.

List of cruise control cars In India

How to use adaptive cruise control on Ford Edge SUV

Adaptive cruise control is a feature that once activated, will automatically keep the vehicle at a predefined distance from the vehicle in front of you on the road. The latest ACC system on Ford Edge, and some other Ford vehicles, also has the ability to automatically steer and keep the vehicle centered in the lane.

cncl meaning cruise control

Ford adaptive cruise control Stop-and-Go function allows the vehicle to come to a complete stop and drive off again as the car in front moves. It allows for a more stress free driving experience during rush-hours.

1. To activate adaptive cruise control, press the ON button on the steering wheel.

2. Then press the SET button on the steering wheel after accelerating the vehicle to your desired speed. You can now take your foot off the accelerator pedal.

3. To adjust the cruising distance, press the gap settings button on the steering wheel.

4. Pressing the gap button will bring up visual representation of the distance on the instrument cluster screen. There are four gap options that you can choose. Pressing the gap button four times will show four bars on the screen. Pressing the button for the fifth time will cycle it back to one bar.

5. The information screen will also show a green icon indicating that the adaptive cruise is active, and also shows cruising maximum speed when there are no vehicles in front.

6. In case the leading vehicle comes to a complete stop, your vehicle will also stop. Now, if the leading vehicle moves again within 3 seconds, then your vehicle will also continue following. But if the vehicle is stationary for more than 3 seconds, the cruise system will automatically deactivate. To resume adaptive cruise, press the RES button on the steering wheel. You can also push the accelerator pedal just slightly to resume.

7. You also have the option to switch to normal cruise control. To do so, press OK button on the steering wheel to bring up settings menu on instrument cluster screen. Scroll down and choose Driver Assist .

8. Then scroll down and choose Cruise Control from the menu.

9. This will open up options menu for Adaptive and Normal cruise. Make your selection using arrow buttons on the steering wheel and press OK .

10. Activating normal mode will disable the ACC, meaning that your vehicle will no longer follow the vehicle in front.

11. To cancel adaptive cruise or normal cruise, simply press the brake pedal, or press CNCL button on the steering wheel. To resume again, press the RES button.

12. Keep in mind that lane centering feature does not automatically gets activated with the adaptive cruise control. You will have to manually activate it every time. To activate it, press the lane centering button on the steering wheel.

13. This feature uses an on-board camera to detect painted road lines, and provides continuous steering assistance. Green vertical lines will appear on the screen to confirm that the feature is active, if they are grey that means the system is on but inactive.

14. Lane centering feature requires the driver to keep hands on the steering wheel at all times. If the system detects hands off the steering wheel for a certain amount of time, it will first give you warning to put your hands back on the wheel. If you don’t heed the warnings, the system will deactivate and also slow down the vehicle to crawling speed while maintaining steering control.

LIM – Electronic speed limiter

Photo of PeterH

Mercedes Benz cars apply a variable speed limiter called the LIM.

All Mercedes cars available in the market today have LIM facilities unlike the older versions, which used to have the cruise controller instead.

The LIM or speed limiter is an optional facility provided to the driver, which enables him to set a maximum cruising speed between thirty kilometers per hour and the cars maximum possible speed.

Once this maximum speed has been set, it gets stored and appears as an icon in the cars instrument cluster.

This provides the driver to increase the accelerating velocity by a single kilometer or ten kilometers at a time to attain the desired limit.

The LIM in a Mercedes Benz can be regarded as an extra precaution against accidents or creation of risky situations.

It is an innovative step taken by Mercedes Corporation to ensure better road safety. The limiter after being set displays the driver’s desired speed limit on the instruments panel.

This is generally in the form of a display indicator. Any violation of this velocity is closely monitored by the speed limiter in the car, which automatically lets the driver know in the form of visual or sound alerts.

This device often comes in use when there is a pre-defined speed limit to follow or while traversing an unknown route.

The LIM in Mercedes Benz car’s often comes with a facility called speed limit assistance. This facility along with the LIM becomes the ultimate tool to avert accidents.

While the latter is used to inform the driver of the relevant issues regarding speed limits and signs, the later can be used to fix required limits hence reducing the toil of the driver.

While there are huge assortments of items devised to help control speed on cars, the LIM facility of Mercedes Benz has surely redefined all its competitors.

— Speedtronic variable speed limiter is the further development of the conventional cruise control explained above, which allows the driver to set a maximum speed limit for themselves (the car) in the range between 30km/h and the vehicles maximum speed.

Pressing the “Lim” switch on the cruise control stalk sets the speed limiter. The desired maximum speed is then stored and appears on the central display in the instrument cluster.

A small orange light is lit on the stalk to indicate that the speed limiting function will be in use if the stalk is moved, as opposed to the Cruise control function.

(They cannot be used simultaneously). The driver can increase the set speed in 10 km/h or single km/h increments by flicking the lever up until the desired maximum speed is reached.

Nissan DTC 1564: ASCD Switch – Malfunction (Voltage Off)

This article is for Nissan made vehicles only.  This code can have different meanings for different manufacturers (most are  related to cruise control) .

P1564 is a common code that can occur in Nissans or Infiniti’s.  It indicates that the ECM has detected an issue with the Automatic Speed Control Device (ASCD) More specifically, with the voltage resistance at the switch itself.

ASCD is just Nissan’s overly complicated way of saying cruise control.  It should not be considered a breakdown risk.

You can see the switch.  It’s just your cruise control buttons.  You’ll still need to pull the airbag/steering assembly to test it.

P1564 Check Engine

P1564 does not have many symptoms other than the check engine light being illuminated (probably why you are here), and the cruise control system not working.

Causes + Fix

Nissan P1564 is almost certainly going to be caused by an issue with the ASCD steering switch.  

ASCD Switch (Most Common Fix)

The ASCD switch is the many buttons on your steering wheel that lets you operate the cruise control.  As you push them, different voltage levels are being sent to the ECM.  This tells the cruise control to engage, reduce speed, increase speed or quit.  

When the wrong voltage is detected, the ECM will disable the cruise control and throw P1564.

More than likely, the switch itself will need replaced, but you should do your due diligence by testing the wiring harness going to the steering wheel first.  You’ll need a multimeter to test the switch itself.  Here’s a great video of a gentleman diagnosing P1564.  It ends up being the switch itself in this case.

There are three pain points where the voltage should be tested:

  • Between the spring switch and the ECM
  • Between the ASCD switch and the steering wheel harness (requires removing the airbag assembly, if you don’t know what you’re doing it can activate and pop you).
  • At the ASCD switch itself.  Check the incoming voltage and outgoing voltage.  Check that linked video a few lines up.  It’s very thorough and can help you through this.

ECM (Not Very Likely) 

If everything checks out with the wiring harness and ASCD switch, it could be the ECM that is at fault.  But, it’s so unlikely that you should double check everything first.

P1564 Conclusion

P1564 is usually caused by a bad ASCD switch.  We recommend taking it to a shop if you aren’t comfortable with taking the steering assembly apart.

SpaceX Starship disintegrates in third test flight but is still labelled a success

News ticker, election results.

Follow all the results of the Brisbane City Council election and Queensland by-elections at our full results page

SpaceX's Starship rocket has successfully made it to space for the first time but disintegrated on its return to Earth. 

The rocket, designed to eventually send astronauts to the Moon and beyond, completed nearly an entire test flight through space on its third try, getting farther than ever before. 

During a webcast of the flight, SpaceX commentators said mission control lost communication with Starship from two satellite systems simultaneously while the spacecraft was re-entering the planet's atmosphere at hypersonic speed.

Spectators gather to watch the spacecraft launch in Texas. They all point at the sky

The spacecraft at that point was nearing a planned splashdown in the Indian Ocean, about an hour after launch from south Texas.

Contact with Starship cut out moments after a live video feed from a camera mounted on the vehicle showed high-definition images of a reddish glow enveloping the silvery spacecraft from the heat of re-entry friction as it plunged earthward.

A few minutes later, SpaceX confirmed that the vehicle had been "lost" — meaning incinerated or broken apart — during the stress of re-entry.

For reasons that were left unclear, SpaceX opted to skip one of the test flight's core objectives — an attempt to re-ignite one of Starship's Raptor engines while it coasted in a shallow orbit.

That milestone is considered key to its future success.

However, completion of many of Starship's intended flight objectives represented progress in the development of a spacecraft crucial to the growing satellite launch business of SpaceX, founded by Elon Musk in 2002, and NASA's Moon program.

NASA chief Bill Nelson congratulated SpaceX on what he called "a successful test flight" in a statement posted on social media platform X.

The US space agency is SpaceX's biggest customer.

SpaceX president Gwynne Shotwell wrote in an X post that the test marked an "incredible day".

The two-stage spacecraft, consisting of the Starship cruise vessel mounted atop its towering Super Heavy rocket booster, blasted off from the company's Starbase launch site near Boca Chica Village on the Gulf Coast of Texas.

The upper-stage Starship reached peak altitudes of 234 kilometres. 

SpaceX's next-generation Starship spacecraft, atop its powerful Super Heavy rocket, lifts off on its third launch.

The spacecraft's previous missions were cut short by explosions minutes after launch.

The company had acknowledged in advance a high probability that its latest flight might similarly end with the spacecraft's demise before the mission profile was finished.

SpaceX's engineering culture, considered more risk-tolerant than many of the aerospace industry's more established players, is built on a flight-testing strategy that pushes spacecraft to the point of failure, and then fine-tunes improvements through frequent repetition.

Engineering goals

Thursday's flight achieved many of the engineering goals set for the mission: a repeat of successful stage separation during initial ascent; the first test of Starship's ability to open and close its payload door in orbit; and the transfer of super-cooled rocket propellant from one tank to another during spaceflight.

What SpaceX failed to demonstrate on top of Starship's re-entry failure and the skipped engine re-ignition test, was an attempt to fly the Super Heavy rocket back to Earth, part of SpaceX's routine strategy of recovering its launch boosters for re-use.

SpaceX officials have said they plan to conduct at least six more test flights of Starship this year, subject to regulatory approval.

The company is required to investigate each test mission failure and deliver its findings and corrective actions to the Federal Aviation Administration for the agency's approval before the vehicle can fly again.

On the whole, Thursday's test (local time) encompassed a fraction of the remaining demonstrations and missions the vehicle must get through before it is proven safe enough to fly people to space.

Mr Musk is counting on Starship to fulfil his goal of producing a large, multipurpose next-generation spacecraft capable of sending people and cargo to the Moon later this decade, and ultimately flying to Mars.

Closer to home, Mr Musk also sees Starship as eventually replacing the SpaceX Falcon 9 rocket as the workhorse in the company's commercial launch business.

It already lofts most of the world's satellites and other payloads to low-Earth orbit.

NASA also has a lot riding on the success of Starship, which the agency is giving a central role in its Artemis program, the successor to the Apollo missions that put astronauts on the Moon for the first time more than 50 years ago.

While NASA executives have embraced Mr Musk's frequent flight-testing approach, agency officials in recent months have made clear their desire to see greater progress with Starship's development as the United States races with China to the lunar surface.
