Overview of drivin

In thi ssection, yo uwillf ind informatio nabout
the following driving safety systems:
R ABS ( Anti-lock Braking System)
R BAS ( Brake Assist System)
R BAS PLUS* ( Brake Assist System Plus*)
R Adaptive brake lamps
R ESP ®
( Electronic Stability Program)
R EBV (electroni cbrake-power distribution)
R ADAPTIVE BRAKE
R PRE-SAFE Brake* (vehicle swithD istronic

i In wintry driving conditions, always use
winter tyres (M+S tyres) and if necessary,
snow chains .Onlyint hisw aywill the driv-
ing safety system sdescribe dinthiss ection

Ris

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

we tors lipper yroads or when driving too close
to the vehicl einfront.
The driving safety system sdescribe dint his
sectio ncan neither reduce thi sriskn or over-
rid ethe laws of physics.
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
tha tthe wheels do not lock when yo ubrake.
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-
tions. ABS works on slippery surfaces ,even
when yo uonlyb rake gently. G

R strong radar reflections, for example in
multi-storey car parks
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

PRE-SAFE ®
Brake can hel pyou to minimise

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
00BA distance warning lamp in the instru-
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

period of time. If you approach an obstacle
and PRE-SAFE ®
Brak edetects arisk of acol-
lision, the system will initially alert you both
visually and acoustically. If you do not brake
or steer ,the vehicle will at first automatically
brake slightly. In the event of an increased
risk of acollision, PRE-SAFE ®
is activated
(Y page 40). If the risk of collision persist sand
you do not brake, manoeuvr eoraccelerate
significantly yourself, an automatic full brake
application may be carried out. G
Risk of accident
Only clearly detected obstacles will trigger a
warning and initiat ebrakin gassistance by
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-
ered
R snow or heavy rain
R interferenc ebyother radar sources
R the possibility of strong radar reflections,
for example in multi-storey car parks
PRE-SAFE ®
Brak edoes not react to persons,
animals, oncoming vehicles, crossing traffic
or when cornering.
PRE-SAFE ®
Brak emay not detec tnarrow
vehicles such as motorcycles and vehicles
drivin gonad ifferentline. G
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
obstacles, for example stopped or parked
vehicles. G
Risk of accident
If, in acritical drivin gsituation ,you do not
receiv eavisual and acoustic warning:
R PRE-SAFE ®
Brak edid not detec tthe risk of
ac ollision
R PRE-SAFE ®
Brak eiss witched off
R PRE-SAFE ®
Brak ehas failed
You must then brake to avoid acollision.

The 00C7 symbol appears in the lower
multi-function display, as long as the HOLD
function is not activated (Y page 135).
On vehicles with parkin gguidance* ,drive
range Pmust be engaged for the symbol to
be displayed.
The radar sensors are automatically deacti-
vated in the vicinity of radio telescope facili-
ties (Y page 304).
For PRE-SAFE ®
Brak etoa ssist you when driv-
ing, the radar senso rsystem must be
switched on and operational.
PRE-SAFE ®
Brak edoes not always detect
complex traffic situation sproperly. You can
terminate the brakin gaction of PRE-SAFE ®
Brak einan on-critical drivin gsituation at any
time if:
R an acoustic and visual warning occurs
R the vehicle brakes
To end this you can either depress the accel-
erator pedal further, activate kickdown or
release the brake pedal. Driving safet
