For this reason, deactivate ASR only briefly
and when absolutely necessary.

When ESP is intervening and the d warning
lamp in the instrument cluster is flashing, leave
ASR on. In this case, only depress the acceler-
ator 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

in deep snow

on sand or gravel

WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.

is intervening.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Vehicles without steering wheel buttons: if the
BAS driving safety system is malfunctioning,
the : warning lamp lights up while the
engine is running ( page 195).

BAS operates in emergency braking situations.
If you depress the brake quickly, BAS automat-
ically increases the brake pressure, thereby
reducing the stopping distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.
EBD (electronic brake force distribu-
tion)
G
WARNING
If EBD is malfunctioning, the rear wheels can
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You should therefore adapt your driving style
to the different handling characteristics. Have
the brake system checked at a qualified spe-
cialist workshop.
EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to improve
handling during braking.
Observe the information on warning and indica-
tor lamps ( page 195).

WARNING
®
If ESP is malfunctioning it will not provide
any vehicle stabilization. There is an increased
risk of skidding or of an accident.
Exercise caution when continuing to drive.

Have ESP checked at a qualified specialist
workshop.
