How does Cruise Control Work and How To Use It?

Posted on

cruise control

Cruise control is a feature commonly found in cars and is used to maintain consistent vehicle speed without the need to constantly press the accelerator pedal. This feature is very useful when driving on toll roads or straight highways, because it allows the driver to avoid leg muscle fatigue caused by pressing the accelerator pedal continuously to maintain vehicle speed.

This feature is one of the convenience features commonly found in many modern cars, and can help reduce stress and fatigue when traveling long distances on the highway. However, keep in mind that this feature should be used wisely and only in situations that are safe and in accordance with local laws. Find out more through the following TransTRACK article!

Cruise control function

The main function of this feature is to maintain consistent vehicle speed without the need to constantly press the gas pedal. It has several important benefits and purposes:


This feature allows drivers to adjust the vehicle speed easily, so they don’t have to constantly press the accelerator pedal. This is very convenient when driving long distances on relatively straight toll roads or highways.

Reduces Fatigue

By eliminating the need to control speed with the feet, this feature can help reduce leg muscle fatigue and overall driver fatigue. This is a particularly useful feature on long journeys.

Save Fuel

This feature can help optimize fuel use by maintaining consistent vehicle speed. This can reduce fuel consumption compared to driving manually by changing speed frequently.

Consistent Speed

Cruise control helps keep the vehicle at a set speed without worrying about going too fast or too slow. This can help in maintaining a speed that complies with the speed limits on the road.

Ease of Overcoming Topography

Some of these advanced feature systems can adjust vehicle speed to the topography of the road, such as adjusting the speed when going up or down a hill to maintain the desired speed.

Excessive Speed Prevention

By setting the maximum speed, cruise control can also help prevent drivers from driving too fast and possibly breaking the law.

Reduces Stress

By eliminating the need to constantly adjust speed, this feature can reduce the driver’s stress levels while driving.

Although this feature has many benefits, the driver must remain alert and ready to take control of the vehicle at any time if the situation requires it. This does not replace the driver’s role in keeping the vehicle in a safe condition and in accordance with traffic rules.

How Cruise Control Works

Cruise control works by controlling the opening of the throttle (gas valve) to maintain vehicle speed at a level set by the driver. Here are the general steps on how cruise control works:

Speed Settings

The driver activates cruise control by moving a switch or button usually located on the steering wheel or center console of the car. They then set the desired speed, often by pressing the “Set” or “Cruise” button on the steering wheel.

Speed Controller

Once the speed is set, the cruise control system will monitor the vehicle speed. If the vehicle slows down or accelerates beyond the set limits, the system will respond by adjusting the throttle opening.

Automatic Throttle Opening

To maintain the desired speed, this feature system will control throttle opening automatically. This means the throttle will be opened wider or narrower, depending on road conditions, until the vehicle reaches the set speed.


The driver can cancel cruise control at any time in several ways. This includes pressing the brake, pressing a special cancel button, or moving a special switch on the steering wheel. This cancellation allows the driver to take control at any time if the situation requires it.

Reaction to Topography

Some of the more sophisticated systems of these features can adjust vehicle speed to cope with changes in road topography. This means the system will increase speed when going down a hill and reduce it when going up a hill, thereby maintaining the desired speed.


It is important to remember that although cruise control can control vehicle speed, the driver is still responsible for controlling the vehicle and maintaining safety. They must remain alert to changing road conditions, traffic and emergency situations.


When drivers want to stop this feature completely, they can press the off button or turn off the cruise control system by moving a special switch on the steering wheel.

How cruise control works varies slightly depending on the make and model of the car, but the basic principle is to maintain a consistent vehicle speed without requiring constant attention to the accelerator pedal. This provides comfort and can help reduce driver fatigue when driving long distances on the highway.

How to Use the Cruise Control Feature

Below are the general steps to use the features of Cruise Control:

On/Off Button (On/Off Button)

Press the “On/Off” button to activate the cruise control feature. This will power on the system and be ready for speed setting.

Res+ (Resume/Accelerate) button

Once the cruise control feature is activated, use the “Res+” (Resume/Accelerate) button to increase vehicle speed. Press this button to restore the last set speed if you have canceled it previously or to accelerate the vehicle from the current speed.

Set Button- (Set/Decelerate)

Use the “Set-” (Set/Decelerate) button to reduce vehicle speed when the cruise control feature is active. Press this button to reduce vehicle speed and reset cruise control speed.

Cancel Button

The “Cancel” button is used to cancel this feature without turning it off completely. This means the driver can still control the vehicle manually. Press this button if you want to stop cruise control temporarily, for example, to avoid a dangerous situation or take over control of the vehicle.

The steps for using cruise control with these buttons may vary slightly between different makes and models of car. Therefore, it is always best to refer to your vehicle owner’s manual for the exact instructions appropriate to your car. Apart from that, make sure you use cruise control wisely and only in safe road conditions and in accordance with applicable traffic rules.
