Switching target vehicles with driver support

At certain speeds, vehicles with automatic transmissions and the driver support functions Adaptive Cruise Control*1 and Pilot Assist can switch target vehicles.

Switching target vehicles

If the target vehicle ahead turns suddenly, there may be stationary traffic ahead.

When driver support is actively following another vehicle at speeds under 30 km/h (20 mph) and switches targets from a moving vehicle to a stationary vehicle, driver support will brake for the stationary vehicle.

 Warning

When driver support follows another vehicle at speeds over approx. 30 km/h (20 mph) and changes target vehicle – from a moving vehicle to a stationary one – driver support will ignore the stationary vehicle and instead accelerate to the stored speed.

  • The driver must then intervene and apply the brakes.

Automatic standby mode when switching targets

Driver support disengages and goes into standby mode if:
  • your vehicle's speed goes under 5 km/h (3 mph) and driver support cannot determine if the target vehicle 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 driver support no longer has a vehicle to follow.
