Ifth ere is damage, consult a qualified
specialist workshop immediately. When driving off-road, sand, mud and
water or
wate r mixed with oil may getinto the brakes.
This may lead toare duction in braking ef fect or
tot al brake failure as a result of increased wear.
The braking characteristics will vary depending
on the material that has entered the sy stem. Clean
the brakes af ter driving off-road. If you
th en notice reduced braking ef fect or hear
scraping noises, ha vethe brake sy stem checked
at a qualified specialist workshop. Adapt your

rear wheels wear more in the cent reofthe
tyre
Do not drive wi thtyres that ha vetoo little tread
dep th. This significantly reduces traction on wet
ro ads (aquaplaning).
On vehicles with the same front and rear wheel
size, you can inter change the wheels every
5000 to10,000 km, depending on thewe ar.
Ensure the direction of rotation is maintained for
th e wheels.

WARNING Risk of an accident due to
va pour poc kets form ing in the brake sys‐
tem
The brake fluid cons tantly absorbs moi sture
from the air. This lo wersthe boiling point of
th e brake fluid. If the boiling point is too lo w,
va pour poc kets may form inthe brake sys‐
te m when the brakes are applied hard.
This impairs the braking ef fect. #
