ABS (Anti-lock Braking System)
General notes
ABS regulate sbrake pressure in such awaythat
the wheels do not lock when yo ubrake. This
allows yo utocontinue steering the vehicl ewhen
braking.
The ò warning lamp in the instrument cluster
lights up when the ignition is switched on. The
lamp goes ou twhent he engine starts running.
Important safety notes
Observe the important safety guideline sfor the
drivin gsafety system(Ypage 62).
ABS works fromas peedof abou t5mph
(8 km/h), regardles sofroad-surface conditions.
ABS works on slippery surfaces ,evenw heny ou
onl ybrake gently.
GWARNING
If ABS is faulty, the wheels could lock when
braking .The steerability an dbraking charac-
teristics maybes everel yimpaired. Addition-
ally ,fur the rdrivin gsafety systems ar edeac-

Ron vehiclesw ith steering wheel buttons
(Ypage 203)
BAS, Hill Start Assist and ESP®and its driving
safety systems and other driving systems also
fail .Observe the notes on the òwarning
lamp and the display messages.
Braking
If ABS intervenes when braking, you wil lfeel a
pulsating in the brake pedal.
The pulsating brake pedalc an be an indication
of hazardous road conditions and functions as a
reminder to take extra care whiled riving.
XIf ABS intervenes:continue to depresst he
brake pedalw ith force until the braking sit-
uatio niso ver.
XTo make afull brake application: depress
the brake pedalw ith full force.
BAS (Brake Assist System)
General notes
BAS operates in emergency braking situations.
If you depresst he brake pedalq uickly, BAS
automatically boosts the braking force, thus
shortening the stopping distance.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 62).
GWARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased .There is arisk of an accident.
In an emergency braking situation, depress
the brake pedalw ith full force. ABS prevents
the wheel sfrom locking.
If BAS is malfunctioning, the ÷warning lamp
lights up whil ethe engine is running
(

Braking
XKeep the brake pedalf irmly depressed until
the emergency braking situation is over.
ABS prevents the wheel sfrom locking.
The brakes willf unction as usual once you
release the brake pedal. BAS is deactivated.
EBD (electroni cbrake force distribu-
tion)
General notes
EBD monitors and controls the brake pressure
to the rear wheels. This enables EBD to improve handling during braking.
Important safety notes
Observe the important safety guidelines for the
driving safety system (Ypage 62).
GWARNING
If EBD is malfunctioning, the rear wheelsc an
lock, e.g. under full braking. This increases the
risk of skidding and an accident.
You shoul dtherefore adapt you rdriving style
to the different handling characteristics. Have
the brake system checked at aqualifieds pe-
cialist workshop.

ESP®(Electronic Stability Program)
General notes
ESP®monitors driving stabilitya nd detectsa
tendenc yofthevehicle to understeer or over-
steer (skidding) in good time. If ESP
®detects
that th evehicle is deviatin gfromt hedirection
desired by th edriver, oneorm orew heels are
braked to stabilizet hevehicle .The engine out-
put is also modified to keep th evehicle on the
desired course within physical limits. ESP
®can
also stabilizet hevehicle durin gbraking.
ESP
®also monitors traction,i .e.p ower trans-
mission between th etires and th eroad surface.
The integrate dtraction control support syou

th er oad surface is no tsufficient ,even ESP
®will
no tallow you to pull away without difficulty. The
type of tires and total weightoft hevehicle as
well as th egradientoft heroad also play acru-
cial role .Tractio ncontrol remains active if you
deactivate ESP

stances.
Xwhen driving off ,apply as little throttle as
possible.
Xadapt your speeda nd driving style to th epre-
vailin groad conditions.
Important safety notes
Observ ethe important safety guidelines for the
driving safety system (Ypage 62).
GWARNING

Trailer stabilization
Observe the important safety guidelines for the
driving safety system (Ypage 62).
GWARNING
If road and weather conditions are poor,
trailer stabilization will not be able to prevent
the vehicle/trailer combination from swerv-
ing. Trailers with ahigh center of gravity can
tip over before ESP
®can detect this. There is
ar isk of an accident.
Always adapt your driving style to the prevail-
ing road and weather conditions.
ESP
®trailer stabilization counteracts critical
driving situations in good time and thereby pro- vides considerable assistance when driving with
at railer. Trailer stabilization is part of ESP
®. If the sensor system and evaluation logic detect
trailer swinging movements, ESP
®trailer stabi-
lization firstly brakes individual vehicle wheels in
at argeted manner .Itthus counteracts swinging
movements. If the swinging movements do not
stop, the vehicle is braked until the vehicle/
trailer combination is stabilized. If necessary,
the vehicle's engine output is limited.
If your vehicle with trailer (vehicle/trailer com-
bination) start stoswerve, you will be able to
stabilize the vehicle/trailer combination only by
braking. ESP
®trailer stabilization helps you to
stabilize the vehicle/trailer combination in this
situation.
ESP
®trailer stabilization is activated above
speeds of about 40 mph (65 km/h).
If ESP
®is switched off or deactivated because of
am alfunction, the trailer stabilization system
will not function.
Crosswind Assist
Observe the important safety guidelines for the
driving safety system (Ypage 62).
Strong crosswind gusts can impair the road-
holding of your vehicle when driving straight
ahead. The Crosswind Assist function integra-
ted in ESP
®reduces these impairments.
Dependin gonthe direction and intensity of the
side wind, Crosswind Assist intervenes auto-
matically. ESP
®intervenes with stabilizing brak-
ing to assist you in keeping the vehicle in the
lane. When Crosswind Assist intervenes, the
display shows the traffic sign for stron gside
winds and the message Crosswind Assist
.
Crosswind Assist is activated automatically
above avehicle speed of approx. 50 mph
(80 km/h) when the vehicle is driving straight
ahead or cornering gently.
Crosswind Assist does not react:
Rin the event of severe jolts and vibrations, e.g.
when driving over uneven surfaces or pot-
holes
Rwhen grip is reduced, e.g. on snow or ice or
when hydroplaning
Crosswind Assist does not work if ESP
®is deac-
tivated or disabled because of amalfunction.
