WARNING
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.
G
WARNING
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.
G
WARNING
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 sur-
faces, check the underside of the vehicle
and the wheels and tires at regular inter-
vals. In particular, remove any trapped for-
eign objects, e.g. stones and branches.
Such foreign objects may:
damage the chassis, the fuel tank or the
R
brake system
cause imbalances and thus vibrations

If there is any damage, inform a qualified
specialist workshop.
When driving off-road and on construction
sites, sand, mud and water mixed with oil, for
example, 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 characteristics.
Driving off-road or on construction sites
increases 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 specialist workshop as soon as
possible.
When driving on rough terrain, do not shift the
transmission into the neutral position. You
could lose control when attempting to brake
the vehicle with the service brake. If your
vehicle cannot manage an uphill slope, drive
back down the slope in reverse gear.
When loading your vehicle for driving off-road
or on a construction site, keep the vehicle's
center of gravity as low as possible.
