WARNING
The distance warning function cannot
always clearly identify objects and com-
plex traffic situations.
In such cases, the distance warning func-
tion may:
give an unnecessary warning
R
not give a warning
R
There is a risk of an accident.
Always pay careful attention to the traffic
situation; do not rely on the distance warn-
ing function alone.
Observe the "Important safety notes" sec-
tion for driving safety systems (
In particular, the detection of obstacles
can be impaired if there is:
dirt on the sensors or anything else cov-

Following damage to the front end of the
vehicle, have the configuration and oper-
ation of the radar sensor checked at a
qualified specialist workshop. This also
applies to collisions at slow speeds where
there is no visible damage to the front of
the vehicle.

The distance warning function issues a
warning at speeds:
of around 30 km/h or more, if, over sev-
R
eral seconds, the distance maintained to
the vehicle travelling in front is insuf-
ficient. The · distance warning lamp
then lights up in the instrument cluster.

Brake immediately in order to increase
the distance from the vehicle in front.
or
X
Take evasive action provided it is safe
to do so.
Due to the nature of the system, particu-
larly complicated but non-critical driv-
ing conditions may also cause the system to
display a warning.
With the help of the radar sensor system,
the distance warning function can detect
obstacles that are in the path of your vehi-
cle for an extended period of time.
Up to a speed of around 70 km/h, the dis-
tance warning function can also react to
stationary obstacles, such as stopped or
parked vehicles.
