Important safety notes
G
WARNING
Fue lish ighly flammable. If you handle fuel
incorrectly, there is arisk of fire and explo-
sion.
You must avoid fire, naked flames, creating
sparks and smoking. Switch off the engine
and, if applicable, the auxiliary heating before
refuelling. G
WARNING
Fuels are poisonous and hazardous to health.
There is adanger of injury.
Do not swallow fuel or let it come into contact
with skin, eyes or clothing. Do not inhale fuel
vapours. Keep fuels out of the reach of chil-
dren. If you or others come into contact with fuel,
observe the following:
R Wash the fuel off any affected areas of skin
with water and soap immediately.
R If you get fuel in your eyes, rinse them thor-
oughly with clean water immediately. Seek
immediate medical attention.
R If fuel is swallowed, seek immediate medi-
cal attention. Do not induce vomiting.
R Change any clothing that has come into
contact with fuel immediately. G
WARNING
Vehicles with adiesel engine:
If you mix diesel fuel with petrol, the flash
point of this fuel mixture is lower than that of
pure diesel fuel. When the engine is running,
components in the exhaust system may over-
heat unnoticed. There is arisk of fire.
Never refuel with petrol. Never add petrol to
diesel fuel. 174
RefuellingDriving and parking

At the onse
tofwinter, have your vehicle win-
terproofed at aqualified specialist workshop.
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.
Observe the notes in the "Winter operation"
section (Y page 398).
Driving with summer tyres Observe the notes in the "Winter operation"
section (Y
page 398).
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.

Protection of the environment is of primary
importance. Treat nature with respect.
