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

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,

BASP LUS does not react to people or ani-

BASP LUS may not detec tnarro wvehicles
such as motorcycles and vehicles driving on

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

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.

visually and acoustically. If you do not brake

risk of acollision, PRE-SAFE ®
is activated
(Y page 40). If the risk of collision persist sand
you do not brake, manoeuvr eoraccelerate

application may be carried out. G
Risk of accident
Only clearly detected obstacles will trigger a

PRE-SAFE ®
Brake.
In particular, the detection of obstacles can
be impaired if ther eis:
R dirt on the sensors or the sensors are cov-

Risk of accident
Depending on the curren tspeed, PRE-SAFE ®
Brak edecelerates your vehicle by up to
4m /s2
before performing possible emer-
genc ybraking. This is equivalent to approx-
imately 40 %ofthe maximum brakin gpower
of the vehicle. You must additionally apply the
brakes yourself in order to preven tacollision
or minimis eanimpact .Automatic emergency
brakin gisnot performed until immediately
prior to an acciden tinthe event that you are
unable to avoid one by, for instance, taking
evasive action. In order to maintain the appropriate distance
to the vehicle in fron
tand thus preven ta
crash, you must apply the brakes yourself.
At speeds up to approximately 70 km/h,
PRE-SAFE ®
Brak ecan also detec tstationary
