WARNING Risk of accident if you do not
ke ep toline of fall on inclines
If yo u drive at an angle or turn on an incline,
th eve hicle could slip side ways, tip and roll‐
ove r. #
Alw ays drive on inclines in the line of
fa ll (straight up or down) and do not
turn. &
WARNING Risk offire due toflammable
materials on hot parts of theex haust
sy stem
Flammable material such as lea ves, grass or
twigs may ignite if they come into contact
wi th hot parts of theex haust sy stem. #
When driving on unpa vedro ads or off-
ro ad, regular lych eck theve hicle under‐
side. #
Remo vetrapped plants or other flam‐
mable material, in particular. #
Ifth ere is damage, consult a qualified
specialist workshop immediately. When driving off-road, subs
tances su chas sand,
mud and water orwate r mixed with oil may get
into the brakes. This may lead toare duction in
braking ef fect or total brake failure as a result of
increased wear. The braking characteristics will
va ry depending on the material that has entered
th e sy stem. Clean the brakes af ter driving off-
ro ad. If youth en notice reduced braking ef fect
or hear scraping noises, ha vethe brake sy stem
ch ecked at a qualified specialist workshop.
Ad just your driving style to thech anged braking
