R ABS ( Anti-lock Braking System)
R BAS ( Brake Assist System)
R BAS PLUS* ( Brake Assist System Plus*)
R Adaptive brake lamps
R ESP ®

winter tyres (M+S tyres) and if necessary,
snow chains .Onlyint hisw aywill the driv-

The ris kofana ccident is significantly
increased by driving too fast. Thi sisparticu-

For thi sreason, always adap tyou rd riving
style to the prevailing roa dand weather con-
ditions. Maintain sufficient distance from
othe rroa du sers and objects on the road. Anti-loc
kBraking System (ABS)
ABS regulate sbrake pressure in such away

Thi sallow syou to continue steering the vehi-
cle when braking.
ABS works from aspeed of abou t8km/h
upwards ,regardless of road-surface condi-

when yo uonlyb rake gently. G

If ABS is deactivated du etoamalfunction,
then BAS, BAS PLUS* and ESP ®
are also
deactivated. There is an increase driskofy our
vehicle skidding in certain situations.
You shoul dalway sadapt your driving styl eto
suit the prevailing roa dand weathe rcondi-
tions. BAS (Brake Assist)
BAS operate sinemergency braking situa-
tions .Ifyoudepress the brake pedal quickly,
BAS automaticall yboosts the braking force,
thus shortening the stopping distance.
X Kee pthe brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheel sfrom locking.
The brakes will function as usua lonce you
release the brake pedal .BAS is deactivated. G
Risk of accident
If BAS ha smalfunctioned ,the braking system
remains available with ful lbrake boosting
effect. However, braking force is not auto-
matically increase dinemergency braking sit-
uations and the stopping distance may
increase. BAS PLUS* (brake assistanc
esys-
tem)
BAS PLUS provides braking assistance in haz-
ardou ssituations and uses radar senso rtech-
nology to asses sthe traffi csituation. G
Risk of accident
BAS PLUS is only an ai dtoassist yo uwhen
driving .You are responsibl efor maintaining a
saf edistance from othe rvehicles, for the vehi-
cle's speed and for braking in goo dtime.
Alway spayattention to the traffi cconditions.
Otherwise, yo umay recognise dangers too late, cause an accident and injure yourself
and others.
BAS PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time .Should yo uapproach adetected obsta-
cle quickly, BAS PLUS calculates the braking
force necessary to avoid arear-end collision.
Should yo uaddit ionall yapply the brakes, BAS
PLUS will automaticall yincreas ethe braking
force to alevel suitabl efor the traffi ccondi-
tions.
If BAS PLUS demand sparticularly hig hbrak-
ing force ,PRE -SAFE ®
is activate dsimultane-
ously.
X Kee pthe brake pedal depressed unti lthe
emergency braking situation is over.
ABS prevents the wheel sfrom locking.
The brakes will work normall yagain when:
R yo ur elease the brake pedal
R no obstacl eisdetected in front of your
vehicle
R there is no longer any danger of arear-end
collision
BAS PLUS is then deactivated.
At speeds up to approximately 70 km/h ,BAS
PLUS can also detect stationar yobstacles,
for example, stopped or parked vehicles.
The radar sensors are automaticall ydeacti-
vate dint he vicinity of radio telescop efacili-
ties (Y page 304).
For BAS PLUS to assis tyou whe ndriving ,the
radar senso rsystem mus tbes witched on and
operational .You can check this by activating
Distronic Plus* (Y page 125) or via the
"Radar sensor" function in the on-board com-
puter (Y page 120). G
Risk of accident
Only clearl yide ntified obstacles will initiate
braking assistance by BAS PLUS. In particular,
the detection of obstacles can be restricted if

BASP LUS does not react to people or ani-
mals, oncoming vehicles and crossing traffic.
BASP LUS may not detec tnarro wvehicles
such as motorcycles and vehicles driving on
ad ifferen tline.
Following acollision or crash-related damage
to the fron tend of the vehicle, have the con-
figuration and operation of the radar sensors
checked at aMercedes-Benz Service Centre.
If BASP LUS is not available due to amalfunc-
tion in the radar sensor system, the braking
system remains available with full brake
boostin geffec tand BAS. Adaptive brake lamps
i Adaptiv ebrake lamps are only available in
certain countries.
If you brake sharply from aspeed of more
than 50 km/ horifb raking is assisted by BAS
or BAS PLUS* ,the brake lamp sflashr apidly.
In this way, traffic travelling behind you is
warned in an even more noticeable manner.
If you brake sharply from aspee dofm ore
than 70 km/h to astandstill, the hazard warn-
ing lamp sare activated automatically.Ift he
brakes are applieda gain, the brake lamps
light up continuously.T he hazard warning
lamp sswitch off automatically if you travel
faster than 10 km/h .You can alsos witch off
the hazard warning lamp susing the hazard
warning switch button (Y page84). ESP
®
(Electronic Stability Program)
ESP ®
monitors driving stability and traction,
i.e. power transmission between tyres and
the road surface.
If ESP ®
detects that the vehicl eisdeviating
from the direction desired by the driver, one
or more wheels are braked to stabilise the
vehicle. If necessary ,the engine outpu tisalso
modified to keep the vehicl eonthe desired
course withi nphysical limits. ESP ®
assists
the drive rwhen pulling away on wet or slip-
pery roads. ESP ®
can alsos tabilise the vehi-
cle during braking.
When ESP ®
intervenes, the 00C6warning
lamp flashes in the instrument cluster. G
Risk of accident
If the 00C6 warning lamp in the instrument
cluster flashes, proceed as follows:
R do not deactivate ESP ®
under any circum-
stances.
R only depress the accelerator peda lasfar as
necessary when pulling away.
R adapt yourd riving style to suitt he prevail-
ing road and weather conditions.
Otherwise, the vehicl ecoulds kid.
ESP ®
cannot reduce the risk of an accident if
you drive too fast. ESP ®
cannot overrid ethe
lawsofp hysics.
! If the vehicl eistobetowed with the front
or rear axle raised, the ignitio nmust be
switched off (key in position 0or 1in the
ignitio nlock). Application of the brakes by
ESP ®
coul dotherwise destroy the brake
system on the front or rear axle.
i Only use wheels with the recommended
tyre sizes. Only then willE SP®
function
properly. 54

ADAPTIVE BRAKE enhances braking safety
and offers increased braking comfort. In addi-
tion to the braking function, ADAPTIVE BRAKE

sion.
Thi sfunction will issue awarning at speeds of
around 30 km/h or more if:
R for aperiod of several seconds, the dis-
tance to the vehicle in front is too short for
the speed at which yo uare travelling. The

ment cluster lights up.
R yo ua re approaching the vehicle in front too
rapidly .Anintermittent warning tone
sounds and the 00BAdistance warning
lamp lights up in the instrument cluster.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning. G
Risk of accident
