Automatic Braking
If the driver fails to respond to the acute warning, the system starts to apply
the brakes automatically with increasing stopping power in several stages.
Brake assist
If the driver brakes inadequate with an impending collision, the system auto-
matically increases braking force.
The braking assistance only occurs as long as the brake pedal is being firmly
pressed down.
Note
■
If an automatic brake intervention is triggered by the system, the pressure in
the brake system increases and the brake pedal cannot be operated with the
normal pedal stroke.
■
The automatic braking interventions can be cancelled by pressing the accel-
erator pedal or by steering intervention.
