In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock Braking System)
R BAS ( Brake Assist System)
R Adaptive brake lamps
R ESP ®
( Electronic Stability Program)
R EBV (electronic brake-power distribution)
i In wintry road conditions, use winter tyres
(M+S tyres) and snow chains if necessary. . G
Risk of accident
The risk of an accident is significantl y
increased by driving too fast. This is partic-
ularly the case when cornering on wet and
slippery roads and when driving too clos e
to the vehicle in front.
The driving safety systems described in thi s
section cannot reduce this risk or override
the laws of physics.
For this reason, always adapt your driving
style to suit the prevailing road and weather
conditions. 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 severa l
times in quick succession (pumping) .
Depress the brake firmly and evenly. Pump-
ing the brake pedal reduces the braking
effect.
Braking If ABS intervenes when braking, you will fee
l
a pulsing in the brake pedal.
If ABS intervenes:
X Continue to depress the brake pedal wit h
force until the braking situation is over.
For full braking application:
X Depress the brake pedal with maximum
force. Safety

Risk of accident
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the
vehicle when braking and the braking dis-
tance may increase.
If ABS is deactivated due to a malfunction,
then BAS and ESP are 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 ,
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 sys-
tem remains available with full brake boost-
ing effect. However, braking force is not
automatically increased in emergency
braking situations and the stopping dis-
tance may increase. Adaptive brake lamps
i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from a speed of mor e
than 50 km/h or if braking is assisted by BAS,
the brake lamps flash rapidly. In this way,
traffic travelling behind you is warned in an
even more noticeable manner .
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 automati-
cally once the vehicle is stationary and the
brake lamps light up constantly if you depres s
the brake pedal again. The hazard warning
lamps switch off automatically if you travel
faster than 10 km/h again. ES
P®
(Electronic Stability Program)
ES P®
monitors driving stability and traction,
i.e. power transmission between the tyres
and the road surface.
If ESP ®
detects that the vehicle is deviatin g
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. The engine output is also modified, if
necessary, to keep the vehicle on the desired
course within the laws of physics. 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 vwarning
lamp flashes in the instrument cluster. G
Risk of accident
If the v warning lamp in the instrumen t
cluster flashes, proceed as follows:
R Do not deactivate ESP ®
under any cir -
cumstances .
R Only depress the accelerator pedal as far
as necessary when pulling away.
R Adapt your driving style to suit the pre -
vailing road and weather conditions.
The vehicle could otherwise go into a skid. Safety

cannot reduce the risk of an accident
if you drive too fast. ESP ®
cannot overrid e
the laws of physics .
! If the vehicle is to be towed with the front
or rear axle raised, the ignition must be
switched off (key in position 0or 1in the
ignition lock). Application of the brakes by
ESP ®
could otherwise destroy the brake
system on the front or rear axle.
! Vehicles with 4MATIC* may not be towe d
with the front or rear axle raised .
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®

properly .
ESP ®
trailer stabilisin g If your trailer begins to lurch, you can only
stabilise the vehicle/trailer combination by
depressing the brake firmly .
In this situation, ESP ®
assists you and detect s
if the trailer begins to snake. ES P®
slows the
vehicle down by braking and limiting the
engine output until the vehicle/trailer com-
bination has stabilised. Trailer stabilising is active from about
65 km/h. G
Risk of accident
If the road and weather conditions are bad,
trailer stabilising will not be able to prevent
the trailer from lurching or reduce the ris k
of accident. Trailers with a high centre of
gravity can tip over before ESP ®
can detect
this .
Trailer stabilising does not work if ESP ®
is
deactivated or switched off because of a mal-
function .
ETS (Electronic Traction Support) Traction control is part of ES
P®
.
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 when you
deactivate 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 .Deactivating/activating ESP
® ESP
®
is activated automatically when the
engine is running.
It may be best to deactivate ES P®
in the fol-
lowing situations:
R when using snow chain s
R in deep sno w
R on sand or gravel G
Risk of accident
Activate ESP ®
as soon as the reason for
deactivation is longer present. ES P®
will
otherwise not be able to stabilise the vehi -
cle if the vehicle starts to skid or a wheel
starts to spin.
If you deactivate ESP ®
:
R ESP ®
no longer improves driving stability.
R The engine's torque is no longer limited and
the drive wheels can spin. The spinning of
the wheels results in a cutting action, which
provides better grip.
R Traction control is still activated.
R ESP ®
still provides support when you
brake. Safety

Risk of accident
If the v warning lamp in the instrumen t
cluster is permanently lit when the engine
is running, ESP ®
is deactivated or not avail-
able due to a malfunction. The risk of your
vehicle skidding is then increased in certain
situations. You should therefore always adapt your
driving style to suit the prevailing road and
weather conditions.
X To activate :press button 1.

tion)
EBV monitors and controls the brake pres-
sure on the rear wheels to improve driving
stability under braking. G
Risk of accident
If EBV is malfunctioning, the brake system
is still available with full brake boosting
effect. However, the rear wheels can stil l
lock, e.g. under full braking. This could
cause you to lose control of your vehicle
and cause an accident. You should there-
fore adapt your driving style to the differen t
handling characteristics. Anti-theft systems
