An 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 selects the desired speed and a time interval to the vehicle ahead. If the camera and radar unit detects a slower vehicle in front of the car, the speed is adapted automatically via the preset time interval to the vehicle. When the road is clear again the car returns to the selected speed.
Warning
The Adaptive cruise control is an aid, which cannot handle all traffic, weather and road conditions.
The driver must always be observant with regard to the prevailing traffic conditions and intervene if the Adaptive cruise control does not maintain a suitable speed or suitable time interval.
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 the function is used.
The driver always bears responsibility for maintaining the correct time interval and speed - even when the Adaptive cruise control is being used.
Adaptive cruise control regulates the speed with acceleration and braking. It is normal for the brakes to emit a low sound when they are being used to adjust the speed.
The adaptive cruise control aims to control the speed in a smooth way. In situations that demand sudden braking the driver must brake himself/herself. This applies in case of large speed differences or if the vehicle in front brakes suddenly. Due to the limitations of the radar unit, braking may come unexpectedly or not at all.
The adaptive cruise control aims to follow the vehicle ahead in the same lane at a time interval set by the driver. If the radar unit cannot see any vehicle in front then the car will instead maintain the speed set and stored by the driver. This also takes place if the speed of the vehicle ahead increases and exceeds the stored speed.
- Adaptive cruise control can follow another vehicle at speed from 0 km/h up to 200 km/h (125 mph).
- The Adaptive cruise control can follow another vehicle at speeds from 30 km/h (20 mph) up to 200 km/h (125 mph).
Warning
Adaptive cruise control is not a collision avoidance system. The driver must intervene if the system does not detect a vehicle in front.
The adaptive cruise control does not brake for humans or animals, and not for small vehicles such as bicycles and motorcycles. Nor for low trailers, oncoming, slow or stationary vehicles and objects.
Do not use the Adaptive cruise control, for example, in city traffic, at junctions, 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 slip roads.
Important
Overview
Controls
Increases stored speed or reactivates the adaptive cruise control and resumes stored speed and time interval
Activate the adaptive cruise control and store the current speed or deactivate the adaptive cruise control
Reduces stored speed
Increases the time interval to vehicles ahead
Reduces the time interval to vehicles ahead
Target vehicle indicator: ACC has detected and is following a target vehicle at the preset time interval
Symbol for time interval to vehicles ahead
In cars equipped with the adaptive cruise control option, the driver can change between CC and ACC - see "Change between Cruise control and adaptive cruise control".
Driver display
- Stored speed
- Speed of vehicle ahead.
- Current speed of your car.
To see different combinations of symbols depending on traffic situation - see the heading "Symbols and messages for the adaptive cruise control".
Collision risk warning
- Acoustic warning signal in the event of a risk of collision
- Warning signal in the event of a risk of collision
- Distance measurement with the camera and radar unit
Adaptive Cruise Control uses approx. 40% of the capacity of the foot brake. If the car needs to be braked more heavily than the adaptive cruise control is capable of and the driver does not brake, the warning lamp and acoustic warning are activated to alert the driver that immediate intervention is required.
Warning
Head-up display*
In cars equipped with a head-up display, the warning is shown on the windscreen by a flashing symbol.
