Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
R ABS ( Anti-lock BrakingSystem)
R BAS ( Brake Assist System)
R BAS PLUS ( BrakeAssist System Plus*)
R Adaptive brake lamps
R ESP ®
(Electronic StabilityProgram)
R EBD ( Electronic Brake-power Distribution)
R ADAPTIVE BRAKE

TRONIC PLUS) Important safety notes
G
Risk of accident
The risk of an accident is significantly
increased by driving too fast. This is particu-
larly the case when cornerin gaswell as on
wet or slippery roads or when driving too close
to the vehicle in front. The driving safet
ysystems described in this
sectio ncan neither reduce this risk nor over-
ride the laws of physics.
For this reason, always adapt your driving
style to the prevailing road and weather con-
ditions. Maintain sufficient distance from
other road users and objects on the road.
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. ABS (Anti-loc
kBrakin gSystem)
Im portan tsafety guidelines G
Ris
kofa ccident
Do not depress the brak epedal several times
in quick succession (pumping). Depress the
brak efirmly and evenly. Pumping the brake
pedal reduces the braking effect.
ABS regulates brake pressure in such away
that the wheels do not lock when you brake.
This allows you to continue steerin gthe vehi-
cle when brakin g.
AB Sw orksfrom aspeed of about 8km/h
upwards, regardless of road-surface condi-
tions. ABS works on slippery surfaces, even
when yo uonly brake gently.
Braking If ABS intervenes whe
nbraking, yo uwill feel
ap ulsing in the brake pedal.
X If ABS intervenes: continue to depressthe
brake pedal with for ceuntil the braking sit-
uation is over.
X To mak eafull brake application:
depress th ebrake peda lwith full force. G
Risk of accident
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the vehi- Driving safet

nbraking and th ebraking dist ance
may increas e.
If ABS is de activated due to amalfunction,
then BAS and ESP are als odeactivated. There
is an increase drisk of you rvehicle skidding in
cer tain situations.
You should always adapt your drivin gstyle to
suit the prevailing road and weather condi-
tions.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func-
tions as areminder to take extra car ewhile
driving. BAS (Br
akeA ssist)
BA So perates in emergency braking situa-
tions. If you depress the brak epedal quickly,
BAS automatically boosts the braking for ce,
thus shortening the stopping distance.
X Keep the brake peda lfirmly depressed until
the emergency brakin gsituation is over.
ABS prevents the wheels from locking.
The brakes will function as usual onc eyou
release the brake pedal. BA Sisd eactiva ted. G
Risk of accident
If BAS has malfunctioned, the braking system
remains available with ful lbrake boosting
effect. However, braking force is not auto-
matically increased in emergency braking sit-
uations and th estoppi ngdistanc emay
increase. BAS PLUS (Brake Assis
tPLUS)
BAS PLU Sprovide sbraking assistance in haz-
ardou ssituation sand use sradar senso rtech-
nology to assess the traffic situation. G
Risk of accident
BAS PLU Siso nly an aid to assist you when
driving. You are responsible for maintaining a
safe distanc efrom other vehicles ,for the vehi-
cle' sspeed and for braking in good time. Alway
spay attention to the traffic conditions.
Otherwise, you may recognise dangers too
late, cause an acciden tand injure yourself
and others.
BAS PLUS can detect obstacle sthat ar einthe
pat hofyour vehicle for an extended period of
time. Should you appr oachad etected obsta-
cle quickly, BA SPLUSc alculates the braking
force necessary to avoid arear-end collision.
Should you additionally apply th ebrakes, BAS
PLUS wil lautomatically increase the braking
force to alevel suitabl efor the traffic condi-
tions.
If BA SPLUS demands particularl yhigh brak-
ing force, PRE-SAFE ®
is activated simultane-
ously.
X Keep the brak epedal depressed until the
emergency braking situation is over.
AB Sp revents th ewheels fr om lockin g.
The bra kesw ill work normally again when:
R you release the brak epedal
R no obstacle is detected in fr ontof your
vehicle
R there is no longer any danger of arear-end
collision
BA SP LUS is then deactivated.
At speeds up to appro ximately 70 km/h ,BAS
PLU Scan also detect stationary obstacles,
for example, stopped or parked vehicles.
The radar sensor system is switched off auto-
matically in the vicinit yofradio telescope
facilities (Y page 324).
For BA SPLUS to assist yo uwhen driving, the
radar sensor system must be switched on and
operational. You can chec kthis by activating
DI ST RONIC PLUS (Y page 160) or via the
"rada rsensor "function in the on-board com-
puter (Y page 208). G

i Adaptive brake lamps are only available in
certain countries.
If you brake sharply from aspeed of more
than 50 km/ horifbraking is assisted by BAS
or BAS PLUS, th ebrake lamp sflash rapidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.

®
(Electronic Stability Program)
Important safety notes If ESP

detect sthat the vehicle is deviating
from the direction desired by the driver ,one
or more wheels are braked to stabilis ethe
vehicle. If necessary, the engin eoutput 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.
If ESP ®
intervenes, the äwarning lamp
flashes in the instrument cluster. G
Risk of accident
If the ä 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 coul dskid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot override the
laws of physics.
! The ignition must be switched off if you
are towing the vehicl ewith the front/rear
axle raised. Interven tion by ESP ®
coul doth-
erwise damage the brake system.
i Only use wheels with the recommended
tyre sizes. Only then will ESP ®
function
properly.
ETS (Electronic Traction Support) Traction control is part of ESP

Traction control brakes the drive wheels indi-
viduall yifthey spin. This enables you to pull
away and accelerate on slipper ysurfaces, for

It may be best to deactivate ESP ®
in the fol-
lowing situations:

Risk of accident
Activate ESP ®
as soon as the situations
described above no longer apply. ESP ®

If you deactivate ESP ®

ESP ®
trailer stabilisation If your trailer begins to lurch, you can only
stabilise the vehicle/
trailer combination by
depressing the brake firmly.
In this situation, ESP ®

ing the engine output until the vehicle/trailer
combination has stabilised.

Risk of accident
