i If the maximum engin espeed for the shift
range is reached and you continue to accel-

even if the shift range is restricted. This
prevents the engine from overrevving.

Vehicles with th eON&OFFROAD pack-
age: if drivin ginsnow or with snow chains,
select the snow program (Y page 249)with
the off- road program selector wheel in the
centre console.

Slippery road surfaces G
WARNING
If you shift down on aslippery road surfac ein
an attempt to increase the engine's braking
effect ,the drive wheels coul dlose their grip.
This increases the risk of skiddin gand having
an accident.
Do not shift down for additional engine brak-
ing on aslippery road surface.
If the vehicle threaten stoskid or cannot be
stopped whe nmovin gatl ow speed:
X Move the transmission to position N.
X Try to bring the vehicle under con trolby
using corrective steering.
i For more information on driving with
snow chains, see (Y page 399).
You should drive particularly carefully on slip-
pery road surfaces. Avoid sudde naccelera-
tion, steering and brakin gmanoeuvres. Off-road driving
Important safety notes G
WARNING
If you drive up asteep incline at an angle or
turn on asteep incline, the vehicle could slip sideways, tip and overturn. There is
arisk of
an accident.
When drivin gupanincline, drive into the line
of fall (upw ards or downwards in astraight
line) and do not turn. G
WARNING
If the vehicle level is high, the vehicle centre
of gravity is raised .This coul dcause the vehi-
cle to tip over more easily on uphill or downhill
gradients. There is arisk of an accident.
Select the lowest possible vehicle level.
When drivin goff-road, sand, mud and water,
possibly mixe dwith oil, for example, could get
into the brakes. This could result in areduced
braking effect or in total brak efailure and also
in increased wear and tear. The braking char-
acteristic schange depending on the material
ingressing the brakes. Clean the brakes after
driving off-road. If you detec tareduce dbrak-
ing effect or grinding noises, have th ebrake
system checked in aqualified specialist work-
sho pass oon as possible. Adapt your driving
style to the differen tbraking characteristics.
Driving off- road increases the likelihood of
damage to the vehicle, which, in turn, can lead
to failure of the mechanical assembly or sys-
tems. Adapt your driving style to suit the ter-
rain conditions. Drive carefully. Have damage
to the vehicle rectified immediately at aquali-
fied specialist workshop.
Do not switch to transmission position N
when driving off-road. You could lose control
of the vehicle if you attempt to brake using
the service brake. If the gradient is too steep,
drive backwards in reverse gear.

General notes Cruis

speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhil lgradients, especiall yifthe
vehicle is laden or towing atrailer, yo umust
select shift range 1,2or 3in good time. By doing so, you will make use of the braking
effec
tofthe engine. This relieves the load on
the brake system and prevents the brakes
from overheating and wearing too quickly.
Use cruise con trolonly if road and traffic con-
ditions make it appropriate to maintain a
steady speed for aprolonged period. Yo ucan

WARNING
Never depress the brake peda lcontinuously
while the vehicle is in motion, e.g. never cause
the brakes to rub by applying constant slight
pedal pressure. This causes the brake system
to overheat, increases the brakin gdistance
and can lead to the brakes failing completely. G

General notes SPE
EDTRONIC brakes automatically so that
you do not exceed the set speed. On long and

vehicle is laden or towing atrailer, yo umust
select shift range 1,2or 3in good time. By
doing so, you will make use of the braking

you need additional braking, depres sthe
brake pedal repeatedly rather than con tinu-
ously.
You can set avariable or permanent limit
speed:
R variable for speedlimits, e.g. in built-up
areas
R permanent for long-term speed restric-
tions, e.g. when drivin gwith winter tyres
