R STEER CONTROL Important safety notes
If yo ufail to adap tyou rd riving style, the driv-
ing safety systems ca nneither reduc ethe risk
of accident nor override the laws of physics.
Drivi ngsafety systems ar emerely aids
designed to assist driving. You are responsi-
ble for the distance to the vehicle in front ,for
vehicle speed and for brakin gingood time.
Always adapt your drivin gstyle to suit the
prevailing road and weather conditions, as
well as the traffic conditions and maintain a
safe distance from the vehicle in front .Drive
carefully.
i Please note that th edriving safetys ys-
tems described only work as effectively as
possibl ewhen ther eisadequate contact
between the tyres and the road surface.
Pay particula rattention to the information
regarding tyres, recommended minimum
tyre tread depth setc. in the "Wheels and
tyres" sectio n(Ypage 356).
In wintr ydriving conditions ,always use
winter tyres (M+S tyres) and if necessary,
snow chains. Only in this way will the driv-
ing safety systems described in this section
work as effec tivel yasp ossible. ABS (Anti-loc
kBrak ing System)
Impor tant safety notes i
Observ ethe "Importan tsafety notes" sec-
tion (Y page 61). ABS regulates brake pressure in such
away
that the wheels do not lock when you brake.
This allows you to continue steering the vehi-
cle when braking.
ABS works from aspeed of about 8km/h
upwards, regardless of road-surfac econdi-
tions. AB Sworksons lippery surfaces, even
when you only brake gently. G
WARNING
If ABS is faulty, the wheels could lock when
braking. This limits the steerability of the vehi-
cle when brakin gand the braking distance
may increase.
If ABS is deactivated due to amalfunction,
then BAS and ESP are also deactivated. There
is an increased risk of your vehicle skidding in
certain situations.
You shoul dalways adapt your drivin gstyle to
suit the prevailing road and weather condi-
tions.
Braking If ABS intervenes whe
nbraking, yo uwill feel
ap ulsing in the brake pedal.
X If ABS intervenes: continue to depressthe
brake pedal with force until the brakin gsit-
uation is over.
X To mak eafull brake application:
depress th ebrake peda lwith full force.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions and func-
tions as areminder to take extr acare while
driving. G
WARNING
Do not depress the brake pedal several times
in quick succession (pumping). Pumping the
brake pedal reduces the braking effect .You
might otherwise not be able to stop the vehi-
cle in tim eand could cause an accident.
Depres sthe brake pedal firmly and smoothly. Driving safety systems
