Adaptive Cruise Control*

Adaptive Cruise Control1 (ACC2) can help the driver to maintain a constant speed, combined with a preset time interval to the vehicle in front.
P5-1507-CitySafety Princip
The camera/radar sensor measures the distance to the vehicle ahead.

Adaptive Cruise Control can help provide a more relaxed driving experience on long trips on highways or long, straight roads with even traffic flows.

The driver sets a speed and a time interval to the vehicle ahead. If the camera/radar sensor detects a slower-moving vehicle ahead, your vehicle's speed will be automatically adapted according to the set time interval to the vehicle ahead. When there are no longer slower-moving vehicles ahead, the vehicle will return to the set speed.

Adaptive Cruise Control is designed to:
  • smoothly regulate speed. The driver must apply the brakes in situations requiring immediate braking. For example, when there are great differences in speed between vehicles or if the vehicle ahead brakes suddenly. Due to limitations in the radar sensor, braking may occur unexpectedly or not at all.
  • follow a vehicle ahead in the same lane and maintain a time interval to that vehicle set by the driver. If the radar unit does not detect a vehicle ahead, it will instead maintain the speed set by the driver. This will also happen if the speed of the vehicle ahead exceeds the set speed for your vehicle.

Steep roads and/or heavy loads

Adaptive Cruise Control is primarily intended to be driven on flat roads. The function may not be able to maintain the correct time interval to the vehicle ahead when driving down steep downgrades. The driver should be extra attentive and prepared to apply the brakes.

Do not use Adaptive Cruise Control if the vehicle is carrying a heavy load or towing a trailer.

 Warning

  • This is not a collision avoidance system. The driver is always responsible and must intervene if the system fails to detect a vehicle ahead.
  • The function does not brake consistently for people or animals and does not brake for small vehicles, such as bicycles and motorcycles. Similarly, it does not brake for low trailers, oncoming, slow-moving or stationary vehicles and objects.
  • Do not use the function in demanding situations, such as in city traffic, at intersections, on slippery surfaces, with a lot of water or slush on the road, in heavy rain/snow, in poor visibility, on winding roads, or on on/off ramps.

 Warning

  • The function is supplementary driver support intended to facilitate driving and help make it safer – it cannot handle all situations in all traffic, weather and road conditions.
  • The driver is advised to read all sections in the Owner's Manual about this function to learn of its limitations, which the driver must be aware of before using the function.
  • Driver support functions are not a substitute for the driver's attention and judgment. The driver is always responsible for ensuring the vehicle is driven in a safe manner, at the appropriate speed, with an appropriate distance to other vehicles, and in accordance with current traffic rules and regulations.

 Note

The function uses the vehicle's camera and radar sensor, which has certain general limitations.

 Important

Only a workshop may perform maintenance on driver support components – an authorized Volvo workshop is recommended.
