i
In wintry driving conditions, always use
winter tyres (M+S tyres) and if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effectively as possible. G
Risk of accident
The risk of an accident is significantly
increased by driving too fast. This is particu-
larly the case when cornering as well as on
wet or slippery roads or when driving too close
to the vehicle in front.
The driving safety systems described in this
section can neither reduce this risk nor over-
ride the laws of physics.
For this reason, always adapt yourd riving
style to the prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road. 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 vehi-
cle 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) .Depress the
brake firmly and evenly. Pumping the brake
pedal reduces the braking effect.
Braking If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
X If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To make a full brake application:
depress the brake pedal with full force. G
Risk of accident
If ABS is faulty, the wheels could lock when
braking .This limits the steerability of the vehi-
cle when braking and the braking distance
may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are also deactivated. There
is an increased risk of your vehicle skidding in
certain situations.
You should always adapt your driving style to
suit the prevailing road and weather condi-
tions. BAS (Brake Assist)
BAS operates in emergency braking situa-
tions. If you depress the brake pedal quickly,
BAS automatically boosts the braking force,
thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. G
Risk of accident
If BAS has malfunctioned, the braking system
remains available with full brake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and the stopping distance may
increase. 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.Int his way,
traffic travelling behind you is warned in an
even more noticeable manner.
If you brake sharply from a speed of more
than 70 km/h to a standstill, the hazard warn-
ing lamps are activated automatically .Ifthe 46

brakes are applied again, the brake lamps
light up continuously. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/ h.You can also switch off
the hazard warning lamps using the hazard
warning switch button (Y page 216).ESP
®
(Electronic Stability Program)
You can selec tbetween the three following
states of ESP ®
:
R ESP ®
is activated.
R ESP ®
Sport is activated.
R ESP ®
is deactivated.
ESP ®
is activated as soon as you start the
engine. When ESP ®
Sport is activated, the
0005 warning lamp lights up in the instrument
panel. When ESP ®
is deactivated, the 0001
and 0002 warning lamps light up in the instru-
ment panel.
Characteristics of ESP ®ESP
®
monitors driving stability and traction,
i.e. power transmission between the tyres
and the road surface.
If ESP ®
detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP ®
assists
the driver when pulling away on wet or slip-
pery roads. ESP ®
can also stabilise the vehi-
cle during braking.
When ESP ®
intervenes, the 0002warning
lamp flashes in the instrument panel. G
Risk of accident
If the 0002 warning lamp in the instrument
cluster flashes, proceed as follows: R
do not deactivate ESP ®
under any circum-
stances
R only depress the accelerator pedal as far as
necessary when pulling away
R adapt your driving style to suit the prevail-
ing road and weather conditions
Otherwise, the vehicle could go into a skid.
ESP ®
cannot reduce the risk of an acciden tif
you drive too fast. ESP ®
cannot override the
laws of physics.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ESP ®
is activated automatically when the
engine is running .Inthe following situations,
it may be better to activate ESP ®
Sport or
deactivate ESP ®
:
R when using snow chains
R in deep snow
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply.O therwise,
ESP ®
will only be able to stabilise the vehicle
to a limited degree if the vehicle starts to skid
or if a wheel starts to spin.
Characteristics of ESP ®
Sport ESP
®
Sport raises the interventio nthreshold
for stabilising the vehicle. This allows for a
sportier driving style on designated race cir-
cuits and may in certain situations improve
the traction in comparison with ESP ®
.
If you activate ESP ®
Sport:
R ESP ®
only improves driving stability to a
limited degree.
R engine torque is only restricted to a limited
degree and the drive wheels are able to
spin. The spinning wheels produce a cut-
ting effect for better traction. Driving safety systems

tifunctio ndisplay. G
Risk of accident
ESP ®
is deactivated if the 0002and0001
warning lamps in the instrument cluster are
lit continuously when the engine is running.
There is an increased risk of your vehicle skid-
ding in certain situations.
You should always adapt your driving style to
suit the prevailing road and weathe rcondi-
tions.
X To activate ESP ®
:when ESP ®
Sport is acti-
vated or ESP ®
is deactivated, press but-
ton 0001briefly.

instrument cluster go out. The message
ESP-ON appears in the multifunction dis-
play.
ETS (Electronic Traction System) Traction control is part of ESP
®
.
Traction control brakes the drive wheels indi-
vidually if they spin. This enables you to pull
away and accelerate on slippery surfaces, for
example if the road surface is slippery on one
side.
Traction control remains active if you deacti-
vate ESP ®
. G
Risk of accident
Traction control cannot reduce the risk of an
accident if you drive too fast. Traction control
cannot override the laws of physics. 48

EBD (Electronic Brake-force Distribu-
tion)
EBD monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability while braking. G
Ris
kofa ccident
If EBV is malfunctioning, the brake system is
still available with full brak eboosting effect.
However, the rear wheels can still lock, e.g.
under full braking. This could cause you to
lose control of your vehicle and cause an acci-
dent. You should therefore adapt your driving
style to the different handling characteristics. ADAPTIVE BRAKE
ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE
also features the hill start assist function
(Y page 221). For further information, see
Driving tips (Y page 277). Anti-theft systems
