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
ch aracteristics.

Depending on theve hicle's equipment, thera dar
sensors are integrated behind the bumpers
and/or behind the Mercedes star. The ultrasonic
sensors are located in the front and rear bump‐
ers. Keep these parts free of dirt, ice and slush
(/ page 489). The sensors must not be cov‐
ered, forex ample bycycle rack s, ove rhanging
loads, sticke rs,fo il or foils toprotect against

can li kewise impair the function of the ultrasonic
sensors. In theev ent of damage tothe bumpers
or radiator grille, or following a collision impact‐

R mainly short-dis tance driving
R frequent operation in mountainous terrain or
on poor road sur faces
R when the engine is of ten le ftidling for long
periods

WARNING Risk of inju rythro ugh dif fer‐
ent wheel sizes
Inter changing the front and rear wheels if the
wheels or tyres ha vediffere nt dimensions
may se verely impair the driving characteris‐
tics.
The disk brakes or wheel suspension compo‐
nents may also be damaged. #
Rotate front and rear wheels on lyifthe

The wear pat tern s on the front and rear wheels
dif fer:
R Front wheels wear more on the shoulder of
th e tyre
R Rear wheels wear more in the cent reofthe

vehicles with the same front and rear wheel
size, you can inter change the wheels every
5,000 to10,000 km, depending on thewe ar.
Ensure the direction of rotation is maintained for

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. #
