Important safety notes
If you fail to adapt your driving style or
become distracted, th edriving sa fetysys-
tems ca nneith er reduce th erisk of accident
no ro verri dethe law sofphysics. Driving
safety system sare mere ly aids desig nedto
assis tdrivi ng.You ar eresponsible for the dis-
tance to the vehicle in fr ont, forvehicle speed
and for braking in good time. Alway sadapt
your drivin gstyle to suit the prevailing road
and weather condition sand maintain asafe
distance from the vehicle in front .Drive care-
fully.
i Thed riving safet ysystems described only
work as effectively as possibl ewhen there
is adequate con tact betwee nthe tyres and
the roa dsurface. Pleas epay special atten-
tion to the notes on tyres, recommended
minimum tyre tread depths ,etc.
(Y page 396).
In wintry driving 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 effectively as possible. ABS (Anti-lock Braking System)
Important safety notes i
Observe the "Important safety notes" sec-
tion (Y page61). G
WARNING
If ABS is faulty, the wheels could lock when
braking .The steerability and brakin gcharac-
teristics ma ybeseverely impaired. Addition-
ally, further driving safet ysystems are deac-
tivated. There is an increased danger of skid-
ding and accidents.
Drive on carefully. Have ABS checked imme-
diatel yata qualified specialist workshop.
When ABS is malfunctioning, other systems,
including driving safety systems, will also
become inoperative. Observe the infor mation on the ABS warning lamp (Y
page 326) and
display messages which may be shown in the
instrument cluster (Y page 291).
ABS regulate sbrake 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.
The yellow !ABS warnin glamp in the
instrument cluster lights up when the ignition
is switched on. It goes out when the engine is
running.
Brakes X
If ABS intervenes: continue to depress the
brake pedal with force until the braking sit-
uation is over.
X To mak eafull brake application:
depress th ebrake peda lwith full force.
If ABS intervenes when braking, you will feel
ap ulsing in the brake pedal.
The pulsating brake pedal can be an indica-
tion of hazardous road conditions, and func-
tions as areminder to take extr acare while
driving.
Off-road ABS An ABS system specifically suited to off-road
terrain is activated automatically once the off-
road program is activated on:
R
Vehicles without the ON&OFFROAD pack-
age (Y page 252)
R Vehicles with the ON&OFFROAD package
(Y page 253)
At speeds below 30 km/h, the front wheels
lock cyclically during braking. The digging-in
effect achieved in the process reduces the
stopping distance when driving off-road. This
limits steering capability. Driving safety systems
