# What is Adaptive Cruise Control and How Does It Work?

![S-Cross-Hybrid-314](https://drive.suzuki.co.nz/hs-fs/hubfs/SZA%20Automobiles/SZA%20Suzuki%20Now%20Newsletter/2026/S-Cross-Hybrid-314.jpg?width=1000&height=563&name=S-Cross-Hybrid-314.jpg)

Adaptive cruise control is a handy driver-assistance feature that helps make longer drives more comfortable, efficient and safer. Here we’ll explain what adaptive cruise control is, how it works and other frequently asked questions, such as when and when not to use it.

## What is Adaptive Cruise Control?

Adaptive cruise control works in a similar way to standard cruise control. You set your vehicle to a chosen speed, and the system maintains it so you can take your foot off the accelerator. What makes adaptive cruise control different is its ability to automatically adjust your speed to match the traffic ahead.

Using sensors such as radar or laser technology mounted at the front of the vehicle, it continuously scans the road for other vehicles and obstacles. Once the traffic slows down, the adaptive cruise control system adjusts your speed according to the distance between your car and the vehicle in front.

In some vehicles, adaptive cruise control can bring the car to a complete stop and restart it again once the traffic in front starts moving again.

Adaptive Cruise Control is one of the many advance driver-assistance features found in our Suzuki [small cars](https://www.suzuki.co.nz/small-cars) and [SUVs](https://www.suzuki.co.nz/suvs).

## The benefits of Adaptive Cruise Control

Using Adaptive Cruise Control can make long-distance driving more relaxed, efficient and economical. Here are two of the main benefits:

Fuel Efficiency - Sharp acceleration uses more energy, so smoother, more consistent cruising with adaptive cruise control can help reduce fuel consumption and lower emissions. Check out some other top tips for improving the fuel efficiency in the car you drive [here](https://drive.suzuki.co.nz/blog/practical-ways-to-improve-your-fuel-efficiency).

Safety - Adaptive cruise control can help reduce driver fatigue by easing the physical and mental effort of constantly adjusting your speed. It can also help prevent accidental speeding and maintain a safer following distance from the vehicle ahead, reducing the likelihood of nose-to-tail collisions.

 Here are some of the other [safety features](https://drive.suzuki.co.nz/blog/8-of-the-latest-car-safety-features-you-need-to-know-about) that can help you avoid or at least minimise injury to you and your loved ones.

## How does Adaptive Cruise Control work?

Typically, the Adaptive Cruise Control buttons are found on the face of the steering wheel for easy and distraction free operation. Here are the basic functions:

ON/OFF: To set Adaptive Cruise Control, press the ON/OFF button. The cruise light will illuminate on the dashboard which means the system is activated. To turn the system off, press again. Turn off when not in use to prevent re-engaging the system by accident.  
SET: This button will set the speed to the current speed you are travelling and the “Cruise Set” icon will appear on the dashboard. You can now take your foot off the accelerator, and the car will maintain the speed for you.  
Each time you press the button, the cruising speed will decrease by 1 km/h.  
RES +: Press this button if you want to increase the cruising speed by 1 km/h. You can also use this button to resume your previously set speed.  
VEHICLE DISTANCE: Use this button to adjust the following distance between yourself and the vehicle ahead.  
CANCEL: To deactivate the Adaptive Cruise Control mode, press this button. Or simply apply pressure to the brake pedal at any time.

## Adaptive Cruise Control FAQs

Can I use adaptive cruise control to self-drive the car?

No, adaptive cruise control cannot self-drive your car. It only automates your vehicle's speed and distance from the car ahead, but it requires you to actively steer, monitor the road, and be ready to brake at all times.

Make sure to:

- Stay alert.
- Keep your brain engaged in driving.
- Scan the road ahead for hazards.

Can I use adaptive cruise control in heavy traffic?

Yes, you can use adaptive cruise control in heavy traffic, provided your car is equipped with a "Stop & Go" function. This feature automatically brakes your car to a complete halt when traffic stops and resumes driving when it moves again.

Can I use adaptive cruise control on winding or hilly roads?

No, adaptive cruise control is best suited to long, straight roads and highways. On winding or hilly roads, it’s safer to control your speed manually, as changing corners, gradients and road conditions need more precise driver skill in relation to braking and accelerating.

Can I use adaptive cruise control in wet or slippery conditions?

No, adaptive cruise control should not be used on wet, icy or slippery roads, as reduced traction can increase the risk of skidding or losing control. In these conditions, it’s safer to manage your speed manually so you can respond more precisely to the road.

What is a safe speed for using adaptive cruise control?

Only use adaptive cruise control at a safe, legal speed that suits the road, the speed limit, the traffic and the weather conditions. Adjust the following distance and speed to suit the driving conditions.

What should I do with my feet when adaptive cruise control is on?

While adaptive cruise control is active, you can rest your foot from the accelerator, but it should still remain close and ready to respond. Always be prepared to take over quickly if road or traffic conditions change.

Check out these videos to some of the most commonly asked questions about adaptive cruise control.
