System limits
ABS may be impaired or may not function if a mal-
function has occurred and the yellow ! ABS
warning lamp lights up continuously on the instru-
ment cluster after the vehicle is started.
If ABS intervenes, you will feel pulsations in the
brake pedal. The pulsating brake pedal may be an
indication of hazardous road conditions and func-
tions as a reminder to take extra care while driving.
If ABS intervenes: keep the brake pedal firmly
depressed until the braking situation has passed.
To carry out maximum full-stop braking: fully
depress the brake pedal.
Function of BAS (Brake Assist System)
& WARNING Risk of an accident caused by a
malfunction in BAS (Brake Assist System)
If BAS is malfunctioning, the braking distance
in an emergency braking situation is increased.
Depress the brake pedal with full force in
#
emergency braking situations. ABS pre-
vents the wheels from locking.
BAS helps you by providing additional brake force
in an emergency braking situation.
If you depress the brake pedal quickly, BAS will be
activated:
BAS will automatically boost the brake force of

When you release the brake pedal, the brakes will
function as usual again. BAS will be deactivated.
Functions of ASR (anti-slip control)
ASR can neither reduce the risk of an accident nor
override 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 will light
up and the drive system performance may be
reduced.
If ASR is malfunctioning, the ÷ indicator lamp
will light up in the instrument cluster and the drive
system performance may be reduced.
Driving and parking 119
ASR improves traction, i.e. the transfer of power
from the tires to the road surface, for a sustained
period and therefore also improves the driving sta-
bility of the vehicle. If the drive axle wheels start to
spin, ASR will brake individual wheels on the drive
axle and limit the output of the drive system. ASR
thus assists you significantly 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 without
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 ÷ warning lamp in the
instrument cluster will flash.
