Forward collision warning
General information
The distance warning function can help you to
minimize the risk of a collision with a vehi-
cle ahead or reduce the effects of such an
accident. If the distance warning function
detects that there is a risk of a collision, you
will be warned visually and acoustically.
Starting the engine also switches on the dis-
tance warning function.
Important safety notes
G
WARNING
The distance warning function does not
react:
R
to people or animals
R
to oncoming vehicles
R
to crossing traffic
R
when cornering
Thus, the distance warning function cannot
provide a warning in all critical situa-
tions. There is a risk of an accident.
Always pay careful attention to the traffic
situation and be ready to brake.
G
WARNING
The distance warning function cannot
always clearly identify objects and com-
plex traffic situations.
In such cases, the distance warning func-
tion may:
R
give an unnecessary warning
R
not give a warning
There is a risk of an accident.
Always pay careful attention to the traffic
situation and do not rely solely on the dis-
tance warning function.
Observe the "Important safety notes" section
for driving safety systems (
Y
page 49).
In particular, the detection of obstacles can
be impaired if:
R
there is dirt on the sensors or anything else
covering the sensors.
R
snow or heavy rain
R
interference by other radar sources
R
the possibility of strong radar reflec-
tions, for example in parking garages
R
a narrow vehicle traveling in front, e.g. a
motorbike
R
a vehicle traveling in front on a different
line
R
new vehicles or after a service on the dis-
tance warning system
Please observe the information in the sec-
tion on running-in the vehicle
(
Y
page 85).
Following damage to the front end of the vehi-
cle, have the configuration and operation of
the radar sensor checked at a qualified spe-
cialist workshop. This also applies to colli-
sions at low speeds where there is no visible
damage to the front of the vehicle.

Starting at a speed of around 4 mph (7 km/h),
the distance warning function warns you if
you rapidly approach a vehicle in front. An
intermittent warning tone will then sound
and the
·
distance warning lamp will
light up in the instrument cluster.
