Adaptive Cruise Control
*15
Adaptive Cruise Control (ACC 16
) helps the
driver maintain a constant speed with a set time interval to the vehicle ahead.
Adaptive Cruise Control can help provide a more relaxed driving experience on long tripson highways or long, straight roads with eventraffic flows.
The camera/radar sensor measures the distance to the vehicle ahead.
The driver sets a speed and a time interval to the vehicle ahead. If the camera/radar sensordetects a slower-moving vehicle ahead, yourvehicle's speed will be automatically adaptedaccording to the set time interval to that vehi-cle. When there are no longer slower-moving vehicles ahead, the vehicle will return to theset speed. If the Curve Speed Assist (CSA)
* function is
activated, it may also affect the vehicle's speed.
WARNING
The function is supplementary driver support intended to facilitate drivingand help make it safer – it cannot han-dle all situations in all traffic, weatherand road conditions.
The driver is advised to read all sec-tions in the Owner's Manual about thisfunction to learn of its limitations,which the driver must be aware ofbefore using the function.
Driver support functions are not a sub-stitute for the driver's attention andjudgment. The driver is always respon-sible for ensuring the vehicle is drivenin a safe manner, at the appropriatespeed, with an appropriate distance toother vehicles, and in accordance withcurrent traffic rules and regulations.
Adaptive Cruise Control regulates speed byaccelerating and braking. It is normal for the

brakes to emit a slight sound when they are being used to adjust speed. Adaptive Cruise Control always attempts to regulate speed smoothly. The driver mustapply the brakes in situations requiring imme-diate braking. For example, when there aregreat differences in speed between vehicles orif the vehicle ahead brakes suddenly. Due tolimitations in the radar sensor, braking mayoccur unexpectedly or not at all. Adaptive Cruise Control is designed to follow a vehicle ahead in the same lane and maintaina time interval to that vehicle set by the driver.If the radar sensor does not detect a vehicleahead, it will instead maintain the speed setby the driver. This will also happen if the speedof the vehicle ahead exceeds the set speed foryour vehicle.
CAUTION
Only a workshop may perform mainte- nance on driver support components – anauthorized Volvo workshop is recom-mended.
