tion of the radar sensor checked at a quali-
fied specialist workshop. This also applies to
collisions at slow speeds where there is no
visible damage to the front of the vehicle.

Using Active Brake Assist

Useful information
With the help of the radar sensor system,
Active Brake Assist can calculate the dis-
tance of your vehicle to the vehicle travelling
in front.
If for several seconds, the distance to the
vehicle ahead is insufficient for the speed
you are driving at, Active Brake Assist alerts
the driver visually.
If a risk of collision is detected, Active Brake
Assist alerts the driver both visually and
acoustically. In addition, Active Brake Assist
prepares the vehicle for a possible emer-
gency braking manoeuvre.
In particularly critical situations Active
Brake Assist may brake autonomously. In
this case, Active Brake Assist continues to
alert the driver both visually and acousti-
cally.
Please note

As a result, Active Brake Assist cannot
intervene in all critical situations. There is
a risk of an accident.
Always pay careful attention to the traffic
situation and be prepared to brake.

Severe jolting, for example in the case of a
collision, may cause the radar sensors to
be misaligned. The function of Active Brake
Assist is then impaired.
There is a risk of an accident.
Deactivate Active Brake Assist. Have Active
Brake Assist checked at a qualified spe-
cialist workshop.
