Tailgate
Important safety notes
GWARNING
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.
!The tailgate swings upwards and to the rear
when opened. Therefore, make sure that
there is sufficient clearance above and behind
the tailgate.
You will find details of the tailgate opening
dimensions under "Technical data"
(
Ypage 313).

Driving off-road
Important safety notes
GWARNING
If you drive on a steep incline at an angle or
turn when driving on an incline, the vehicle
could slip sideways, tip and rollover. There is a risk of an accident.
Always drive on a steep incline in the line of
fall (straight up or down) and do not turn the
vehicle.
GWARNING
When driving off-road, your body is subject to
forces from all directions, due to the uneven
surface. You could be thrown from your seat,
for instance. There is a risk of injury.
Always wear a seat belt, even when driving off-
road.
GWARNING
If you drive over obstacles or in ruts, the steer-
ing wheel may jerk out of your grip, causing
injury to your hands.
Always hold the steering wheel firmly with
both hands. When driving over obstacles, you
must expect steering forces to increase
briefly and suddenly.
GWARNING
Flammable material such as leaves, grass or
twigs may ignite if they come into contact with
hot parts of the exhaust system. There is a risk of fire.
When driving off road or on unpaved roads,
check the vehicle's underside regularly. In
particular, remove parts of plants or other
flammable materials which have become
trapped. In the case of damage, contact a
qualified specialist workshop.
!When driving off-road or on unpaved surfa-
ces, check the underside of the vehicle and
the wheels and tires at regular intervals. In
particular, remove any trapped foreign
objects, e.g. stones and branches.
Such foreign objects may:
Rdamage the chassis, the fuel tank or the
brake system
Rcause imbalances and thus vibrations
Rbe flung out when you continue driving
If there is any damage, inform a qualified spe-
cialist workshop.
When driving off-road and on construction sites,
sand, mud and water mixed with oil, for exam-
ple, may get into the brakes. This may lead to a
reduction in braking performance or total brake
failure, also as a result of increased wear. The
braking characteristics will vary depending on
the material that has got into the system. Clean
the brakes after driving off-road. If you then
notice reduced braking performance or hear
scraping noises, have the brake system checked
at a qualified specialist workshop. Adjust your
driving style to the changed braking character-
istics.
Driving off-road or on construction sites increa-
ses the possibility of vehicle damage which may
in turn lead to the failure of certain assemblies
and systems. Adapt your driving style to the off- road driving conditions. Drive carefully. Have
any vehicle damage rectified at a qualified spe-
cialist workshop as soon as possible.
When loading your vehicle for driving off-road or
on a construction site, keep the vehicle's centerof gravity as low as possible.
Rules for driving off-road
!Always bear the vehicle's ground clearance
in mind and avoid obstacles, e.g. deep ruts.
Obstacles may damage the following parts of the vehicle:
Rthe chassis
Rthe drive train
Rthe fuel and supply tanks
For this reason, you should always drive
slowly when driving off-road. If you have to
