button on the steering wheel (2).The set speed in the center of the speedometer will change from BEIGE to GRAY and the time interval indicator and the target vehicle symbol (if any) will go out.
Warning
- If Adaptive Cruise Control is in standby mode, the driver must intervene and regulate both speed and distance to the vehicle ahead.
- If the vehicle comes too close to a vehicle ahead when Adaptive Cruise Control is in standby mode, the driver can be warned of the short distance by the Distance Alert* function.
Standby mode due to action by the driver
Adaptive Cruise Control will be temporarily deactivated and put in standby mode if:
- the brakes are applied
- the gear selector is moved to N
- the vehicle is driven faster than the set speed for more than 1 minute
Temporarily increasing speed using the accelerator pedal, e.g. when passing another vehicle, will not affect the setting. The vehicle will return to the set speed when the accelerator pedal is released.
Automatic standby mode
Adaptive Cruise Control is dependent on other systems, such as Electronic Stability Control (ESC2). If any of these other systems stops working, Adaptive Cruise Control will automatically switch off.
Warning
With automatic standby mode, the driver is warned by an acoustic signal and a message on the instrument panel.
- The driver must then regulate vehicle speed, apply the brakes if necessary, and maintain a safe distance to other vehicles.
Adaptive Cruise Control may go into standby mode if:
- your vehicle's speed goes below 5 km/h (3 mph) and ACC cannot determine if the vehicle ahead is stationary or if it is another object, e.g. a speed bump.
- your vehicle's speed goes under 5 km/h (3 mph) and the vehicle ahead turns so that ACC no longer has a vehicle to follow.
- the driver opens the door.
- the driver unbuckles the seat belt.
- the engine speed (rpm) is too low/high.
- one or more of the wheels lose traction.
- the brake temperature is high.
- the parking brake is applied.
- the camera/radar sensor is covered by snow or heavy rain (the camera lens/radar waves are blocked)
