Driving safety systems

Braking
If ABS intervenes when braking, you will feel a
pulsating in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func-
tions as a reminder to take extra care while
driving.
If ABS intervenes: continue to depress the
X
brake pedal with force until the braking sit-
uation is over.
To make a full brake application:
X
depress the brake pedal with full force.
ASR (acceleration skid control)
General notes
Important safety notes
Observe the important safety guidelines for
the driving safety system (
ASR can neither reduce the risk of an accident
nor suspend the laws of physics if the driver
does not pay attention when pulling away or
accelerating. ASR is only an aid. Always adapt
your driving style to suit the prevailing road
and weather conditions.
Vehicles without steering wheel buttons: if
ASR is malfunctioning, the : indicator
lamp lights up while the engine is running and
the engine power may be reduced
( page 218).
Y
ASR significantly improves traction, i.e. the
transmission of power from the tires to the
road surface, and thus increases the vehicle's
driving stability. If the driving wheels start to
spin, ASR brakes individual drive wheels and
limits the engine torque. ASR thus signifi-
cantly assists you when pulling away and
accelerating, especially on wet or slippery
roads.
If traction on the road surface is not sufficient,
even ASR will not allow you to pull away with-
out difficulty. The type of tires and total
weight of the vehicle as well as the gradient of
the road also play a crucial role.
If ASR intervenes, the d warning lamp in
the instrument cluster flashes.
Activating/deactivating ASR
G
If deactivated, ASR will not attempt to stabi-
lize the vehicle during pulling away and accel-
eration. There is an increased risk of skidding
and of an accident.
Only deactivate ASR in the situations descri-
bed in the following.
! If you deactivate ASR, ESP
vene to stabilize the vehicle. Frequent brak-
ing automatically triggered by ESP
damage the brake system.
For this reason, deactivate ASR only briefly
and when absolutely necessary.
page 57).
Y
When ESP
ing lamp in the instrument cluster is flashing,
leave ASR on. In this case, only depress the
accelerator pedal as far as required when
pulling away.
Press the à button.

If ASR is deactivated, the d warning
lamp in the instrument cluster lights up.
ASR is automatically activated when the
engine is started.
It may be best to deactivate ASR briefly in the
following situations:
when using snow chains
R
in deep snow
R
on sand or gravel
