good time, and for staying in lane. Always adapt
your driving style to suit the prevailing road and
weather conditions and maintain as afe distance
from the vehicle in front .D rive carefully.
The driving safety systems described only work
as effectively as possible when there is ade-
quate contact between the tires and the road
surface. Pay particular attention to the informa-
tion regarding tires, recommended minimum
tire tread depths etc. in the "Wheels and tires"
section ( Y
page 255).
In wintry driving conditions, always use winter
tires (M+S tires) and if necessary, snow chains.
Only in this way will the driving safety systems
described in this section work as effectively as
possible.
ABS (Anti-lock Braking System)
General information ABS regulates brake pressure in such aw ay that
the wheels do not lock when you brake. This
allows you to continue steering the vehicle when
braking.
The % ABS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out when the engine is running.
ABS works from as peed of about 5m ph
(8 km/h), regardless of road-surface conditions.
ABS works on slippery surfaces, even when you
only brake gently.
Important safety notes
i Observe the "Important safety notes" sec-
tion ( Y
page 54).
G WARNING
If ABS is faulty, the wheels could lock when
braking. The steerability and braking charac-
teristics may be severely impaired. Addition-
ally ,f urther driving safety systems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diately at aq ualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the information
on the ABS warning lamp ( Y
page 204) and dis- play messages which may be shown in the
instrument cluster ( Y
page 179).
Braking X
If ABS intervenes: continue to depress the
brake pedal vigorously until the braking sit-
uation is over. X
To make af ull brake application: depress
the brake pedal with full force.
If ABS intervenes when braking, you will feel a
pulsing in the brake pedal.
The pulsating brake pedal can be an indication
of hazardous road conditions, and functions as a
reminder to take extr ac are while driving.
BAS (Brake Assist System)
General information BAS operates in emergenc yb raking situations.
If you depress the brake pedal quickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
i Observe the "Important safety notes" sec-
tion ( Y
page 54).
G WARNING
If BAS is malfunctioning, the braking distance
in an emergenc yb raking situation is
increased. There is ar isk of an accident.
In an emergenc yb raking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Braking X
Keep the brake pedal firmly depressed until
the emergenc yb raking situation is over.
ABS prevent st he wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.Driving safety systems 55

If the lanes are narrow, vehicles driving in the
lane beyond the lane nex ttoy our vehicle may be
indicated, especially if the vehicles are not driv-
ing in the middle of their lane. This may be the
case if ther ea re vehicles driving at the inner
