Notes on off-road driving
& WARNING Risk of accident if you do not
keep to line of fall on inclines
If you drive at an angle or turn on an incline,
the vehicle could slip sideways, tip and roll‐
over.
Always drive on inclines in the line of
#
fall (straight up or down) and do not
turn.
& WARNING Risk of fire due to flammable
materials on hot parts of the exhaust
system
Flammable material such as leaves, grass or
twigs may ignite if they come into contact
with hot parts of the exhaust system.
When driving on unpaved roads or off-
#
road, regularly check the vehicle under‐
side.
Remove trapped plants or other flam‐
#
mable material.
If there is damage, consult a qualified
#
specialist workshop immediately.
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 effect or total brake failure as a result of
increased wear. The braking characteristics will
vary depending on the material that has entered
the system. Clean the brakes after driving off-
road. If you then notice reduced braking effect
or hear scraping noises, have the brake system
checked at a qualified specialist workshop.
Adjust your driving style to the changed braking
characteristics.
