Warning and automatic braking
Fig. 213
Instrument cluster display: Warning or emergency
braking at low speed
Read and observe and on page 179 first.
Emergency braking at low speed
If there is a risk of collision in a vehicle speed range of about 5 km/h to 30
km/h, the system triggers an automatic braking.
With automatic braking, the warning light
» Fig. 213 appears in the display.
Advance warning
If the system detects a risk of collision, the warning light
» Fig. 213 appears
in the display and you will hear an acoustic signal.
The pre-warning display can occur in the following situations.
▶
If there is a risk of collision with a moving obstacle at a driving speed range
of approx. 30 km/h to approx. 210 km/h.
▶
If there is a risk of collision with a stationary obstacle at a driving speed
range of approx. 30 km/h to approx. 85 km/h.
With a warning the brake pedal must be pressed or the moving obstacle is
to be avoided!
Acute alert
If the driver does not react to the advance warning when in danger of a colli-
sion with a moving obstacle, the system briefly applies the brake automatically
via an active brake intervention to draw attention to the potential danger of a
collision again.
Automatic Braking
If the driver does not respond to the acute warning, the system begins to au-
tomatically brake the vehicle.
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 acceler-
ator pedal or by steering intervention.
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.
