Changing target with adaptive cruise control

In combination with automatic gearbox, the adaptive cruise control (ACC1) has functionality for change of target at certain speeds.

Change of target

P5-1507-ACC RadarSensorTargetChange
If the target vehicle in front suddenly turns then there may be stationary traffic in front.

When adaptive cruise control is following another vehicle at speeds below 30 km/h (20 mph) and changes target from a moving to a stationary vehicle, the adaptive cruise control will slow down for the stationary vehicle.

 Warning

When the adaptive cruise control is following another vehicle at speeds in excess of approx. 30 km/h (20 mph) and the target is changed from a moving vehicle to a stationary vehicle, the adaptive cruise control will ignore the stationary vehicle and instead accelerate to the stored speed.

  • The driver must then intervene him/herself and brake.

Automatic standby mode with change of target

The adaptive cruise control is disengaged and set in standby mode:
  • when the speed is below 5 km/h (3 mph) and the adaptive cruise control is uncertain whether the target object is a stationary vehicle or some other object, such as a speed bump.
  • when the speed is below 5 km/h (3 mph) and the vehicle ahead turns off so the adaptive cruise control no longer has a vehicle to follow.
