If you failtoadapt yourdriving style,the
driving safetysystems canneither reducethe
risk ofaccident noroverride thelaws of
physics. Drivingsafety systems aremerely
aids designed toassist driving. Youare
responsible forthe distanc eto the vehicle in
fron t,for vehicle speedandforbraking in
good time. Always adaptyourdriving styleto
suit theprevailing road/weather conditions,
as well asthe traff iccondit ionsandmaintain
a safe distanc eto the vehicle infron t.Drive
carefully. i
Please
notethat thedriving safety
systems described onlywork aseffect ively
as possible whenthereisadequa tecont act
between thetires andtheroad surface. Pay
particular attentiontothe inform ation
regarding tires,recomm endedminimum
tire tread depths etc.inthe "Wheels and
tires" section(Ypage 350).
In wintry driving conditions,alway suse
winter tires(M+S tires)andifnecess ary,

driving safetysystems described inthis
sect ionwork aseffect ivelyaspossible. ABS
(Anti-lock Braking System )
Impor tantsafety notes i
Observe
the"Importan tsafet yno tes"
sec tion(Ypage 61).
AB Sr egulates brakepressure insuch away
that thewheels donot lock when youbrake.
This allows youtocon tinue steer ingthe
vehicle whenbrakin g.
AB Sw orks from aspeed ofabout
5m ph(8 km/ h)upwards, regardless ofroad-
surface condition s.AB Sw orks onslippery
surfaces, evenwhen youonly brake gently. G

G If
the ABS malfunct ions,other driving systems
such asthe BAS orthe ESP ®
are also switched
off. Observe indicator andwarning lampsthat
may come onaswell asmessages inthe
multifunct iondisplay thatmay appear.
If the ABS malfunct ions,thewheels maylock
during hardbraking, reducing thesteering
capability andexten dingthebraking distance.
The ! warning lampinthe instr ument
cluster lightsupwhen theignition isswitched
on. Itgoes outwhen theengine isrunnin g.
Br aking If
ABS intervenes whenbraking, youwillfeel
a pulsing inthe brake pedal.
X IfABS intervenes: continue todepress the
brake pedalwithforce untilthebraking
situation isover.
X To mak eafull brake application:
depress thebrake pedalwithfullforce.
The pulsating brakepedalcanbean

funct ionsasareminder totake extracare
while driving. G
WARNIN
G Do
not pump thebrake pedal. Usefirm, steady
brake pedalpressure instead.Pumping the
brake pedaldefeats thepurpose ofthe ABS
and significant lyreduces braking
effect iveness. BAS
(BrakeAssist System) i
Observe
the"Important safetynotes"
section (Ypage 61).
BAS operates inemergenc ybraking
situations. Ifyou depress thebrake pedal
quickly, BASautomatically booststhebraking
force, thusshorten ingthe stopping distance.

Therefore, thebraking distancemay increase. BAS
