Important safety notes
G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. If the tailgate is open when the engine is running, particu-
larly if the vehicle is moving, exhaust fumes
could enter the passenger compartment.
There is a risk of poisoning.
Turn off the engine before opening the tail-
gate. Never drive with the tailgate open. G
WARNING
If objects, luggage or loads are not secured or not secured sufficiently, they could slip, tip
over or be flung around and thereby hit vehicle
occupants. There is a risk of injury, especially when braking or abruptly changing directions.
Always store objects so that they cannot be
flung around. Secure objects, luggage or
loads against slipping or tipping before the
journey.
! The tailgate swings upwards and to the rear
when opened. Therefore, make sure that
there is sufficient clearance above and behind
the tailgate.
The opening dimensions of the tailgate can be

you are changing the wiper blades, you can be trapped by the wiper arm. There is a risk of
injury.
Always switch off the windscreen wipers and
ignition before changing the wiper blades.
! To avoid damaging the windscreen wiper
blades, make sure that you touch only the
wiper arm of the windscreen wiper.

arm is folded away from the windscreen/rear
window.
Never fold a windscreen wiper arm without a
wiper blade back onto the windscreen/rear
window. Hold the windscreen wiper arm firmly when
you change the wiper blade. If you release the
wiper arm without a wiper blade and it falls
onto the windscreen/rear window, the wind-
screen/rear window may be damaged by the
force of the impact.

twigs can gather between the underbody and
the underbody panelling. If these materials
come in contact with hot parts of the exhaust
system, they can catch fire.
In such situations, have the vehicle checked
and repaired immediately at a qualified spe-
cialist workshop. If on continuing your jour-
ney you notice that driving safety is impaired, pull over and stop the vehicle immediately,
paying attention to road and traffic condi-
tions. In such cases, consult a qualified spe-
cialist workshop.
When driving off-road, substances such as sand,
mud and water or water mixed with oil may get
into the brakes. This may lead to a reduction in
braking performance or total brake failure as a
result of increased wear. The braking charac-
teristics will vary depending on the substances
that get into the brakes. Clean the brakes after
driving off-road. If you notice grinding noises or a reduction in braking performance, have the
brake system checked at a qualified specialist
workshop immediately. Adapt your driving style
to the altered braking characteristics.
Driving off-road increases the possibility of dam- age to the vehicle, which may cause assemblies
or systems to fail. Adapt your driving style to the conditions of the terrain. Drive carefully. Have
vehicle damage rectified immediately at a quali-
fied specialist workshop.
Do not shift into transmission position Nwhen
driving off-road. You could lose control of the
vehicle if you attempt to brake the vehicle using
the service brake. If the gradient is too steep for your vehicle, back up in reverse gear.

Observe the following notes:
R Stop the vehicle before driving off-road. If
necessary, select the offroad program
(Y page 229) or shift to the LOW RANGE off-
road gear (Y page 230).
R Select a vehicle level suitable for the off-road
terrain. To avoid damaging the vehicle, ensure
sufficient ground clearance at all times.
R Make sure that items of luggage and loads are
stowed safely and are well secured
(Y page 316).
R Always keep the engine running and in gear
when driving on a downhill gradient. Activate
DSR (Y page 227).
R Drive slowly and evenly, if necessary at walk-
ing pace.
R Ensure that the wheels are in contact with the
ground at all times.
R Drive with extreme care on unknown off-road
routes where visibility is poor. For safety rea-
sons, get out of the vehicle first and survey
the off-road route.
R Look out for obstacles such as rocks, holes,
tree stumps and furrows.
R Take care when turning on an uphill or down-
hill slope or when driving across a slope. The
vehicle could otherwise tip over.
R Always keep the doors, the tailgate and the
sliding sunroof closed while the vehicle is in
