The adaptive cruise control provides a more relaxing driving experience on long journeys on motorways and long straight main roads in smooth traffic flows.
The driver sets the desired speed and time interval to the car in front. When the radar detector detects a slower vehicle in front of the car, the speed is automatically adapted to that. When the road is clear again the car returns to the selected speed.
If the adaptive cruise control is switched off or set to standby mode and the car comes too close to a vehicle in front, then the driver is warned instead by the distance warning function about the short distance.
The driver must always be observant with regard to the traffic conditions and intervene when the adaptive cruise control is not maintaining a suitable speed or suitable distance.
The adaptive cruise control cannot handle all traffic, weather and road conditions.
Read all the sections about the adaptive cruise control in the owner's manual in order to learn about its limitations, of which the driver should be aware before it is used.
The driver always bears responsibility for maintaining the correct distance and speed, even when the adaptive cruise control is being used.
Maintenance of adaptive cruise control components must only be performed at a workshop - an authorised Volvo workshop is recommended.
For a limited time after the service, the ACC function can have a somewhat limited range. The system is calibrated whilst driving and full function returns automatically.
Cars with automatic gearbox have enhanced functionality with the adaptive cruise control's Queue assistance function.
