Driving safety systems
ABS (Anti-lock Braking System)
ABS regulates brake pressure in such a
way that the wheels do not lock when you
brake. This allows you to continue steering
the vehicle when braking.
ABS works from a speed of about 8 km/h
upwards, regardless of road-surface condi-
tions.
ABS works on slippery surfaces, even
when you only brake gently.
G
Risk of accident
Do not depress the brake pedal several
times in quick succession (pumping). De-
press the brake firmly and evenly. Pumping
the brake pedal reduces the braking effect.
Braking
When ABS intervenes when braking, you
will feel a pulsing in the brake pedal.
If ABS intervenes:
E
continue to depress the brake pedal
with force until the braking situation is
over
68
For full braking application:
E
depress the brake pedal with maximum
force
G
Risk of accident
You should always adapt your driving style
to suit the prevailing road and weather con-
ditions and maintain a sufficient distance
from other road users and objects on the
road.
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the ve-
hicle when braking and the braking distance
may increase.
If ABS is deactivated due to a fault, then
BAS is also deactivated.
BAS (Brake Assist)
BAS operates in emergency braking situa-
tions. If you depress the brake pedal
quickly, BAS automatically boosts the
braking force and thus shortens the stop-
ping distance.
E
Keep the brake pedal firmly depressed
until the emergency braking situation is
over.
ABS prevents the wheels from locking.
Nur fuer internen Gebrauch Nur fuer internen Gebrauch
The brakes will function as usual once you
release the brake pedal. BAS is deacti-
vated.
G
Risk of accident
If BAS has malfunctioned, the braking sys-
tem remains available with full brake boost-
ing effect. However, braking force is not au-
tomatically increased in emergency braking
situations and the stopping distance may in-
crease.

Adaptive brake lamps

i
Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of more
than 50 km/h or if braking is assisted by
BAS, the brake lamps flash rapidly. This
warns traffic travelling behind.
If you brake from a speed of more than
70 km/h and bring the vehicle to a halt,
the hazard warning lamps switch on auto-
matically once the vehicle is stationary
and the brake lamps light up constantly if
you depress the brake pedal again. The
hazard warning lamps switch off automati-
cally if you travel faster than 10 km/h.
