CAUTION
The system can slow down the vehicle to a standstill. If the vehicle continues
to roll forward after stopping, then it should be stopped with the footbrake.

ahead of the vehicle up to a distance of about 10 metres
The system interventions take place when a risk of collision is detected as fol-
lows.
▶
The brake system is prepared for an emergency stop.
▶
If the driver fails to respond to a detected danger, an automatic braking ac-
tion is performed.
The system can intervene if the following basic conditions apply.
The engine is running.
The system is activated.
The vehicle speed is about 5-30 km/h.
The field of view of the laser sensor is not impaired.
The system can, for example, be affected in the following situations or not
be available.
▶
When visibility is poor, (e.g. fog, heavy rain, thick snowfall).
▶
Driving around "sharp" bends.
▶
When fully pressing down the accelerator pedal.
When the laser sensor is dirty or obscured.
▶
When the vehicles are very dirty and have a low level of reflection.

If the system is not available or there is a system malfunction, the message and
the warning light appears on the display of the instrument cluster flashes in
a slow sequence.
WARNING
Do not cover the windscreen in the area of the laser sensor. This can lead
to impaired function of the sensor - risk of accidents!
WARNING
The laser beam from the laser sensor can cause serious eye injuries. The la-
ser beam is not visible to the human eye.
Never use optical devices, e.g. a range-finder camera or magnifying glass
■
to look into the laser sensor.
The laser beam can also be active when the system is disabled or is not
■
available.
CAUTION
Remove any snow from the windscreen in the area of the laser sensor using a
■
hand brush and any ice with a solvent-free de-icing spray.
If the laser sensor range on the windscreen has scratches, cracks, etc., re-
■
- .
place the windscreen.
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.
Automatic braking interventions by the emergency brake function can be
■
terminated by pressing the clutch or the accelerator or by moving the steering
wheel.
