Adaptive cruise control* - symbols and messages
The adaptive cruise control (ACC – Adaptive Cruise Control) helps the driver to maintain an even speed combined with a pre-selected time interval to the vehicle ahead.
Sometimes the adaptive cruise control may display a symbol and/or text message. Here are some examples - follow the recommendation given if appropriate:
|The symbol is GREEN||The car maintains the stored speed.|
|The symbol is WHITE||Adaptive cruise control is set to standby mode.|
|Standard cruise control is selected manually.|
|Set ESC to Normal to enable Cruise||The adaptive cruise control cannot be activated until the Stability system (ESC) has been set in Normal mode.|
|Adaptive cruise control cancelled||The adaptive cruise control has been deactivated - the driver has to regulate the speed himself.|
|Adaptive cruise control unavailable|
The adaptive cruise control cannot be activated.
This could be due to:
|Radar blocked See manual|
The adaptive cruise control is temporarily disengaged.
The driver can then choose to switch to normal Cruise control (CC) - a text message provides information on appropriate alternatives.
Read about radar sensor limitations.
|Adaptive cruise control Service required|
The adaptive cruise control is disengaged.
|Press brake to hold vehicle + acoustic alarm1|
The car is stationary and the cruise control will release the foot brake to allow the parking brake to take over and hold the car, but a fault in the parking brake means the car will shortly begin to roll.
|Below 30 km/h Lead vehicle required1||Shown in the event of attempts to activate the adaptive cruise control at speeds below 30 km/h (20 mph) without a vehicle in front within the activation distance.|
