When topping up the oil, take care not to

Risk of injury
The cooling system is pressurised. There-
fore, only unscrew the cap once the engine
has cooled down. This means the coolant
temperature gauge must display less than
70 °C. You could otherwise be scalded by
escaping hot coolant.
Coolant consists of water and antifreeze/cor -
rosion inhibitor. Only check the coolant leve l
when the vehicle is on a level surface and th e
engine has cooled down. Checking the coolant level The expansion tank is located in the engin

Tyres and wheels

may be adversely affected. In addition, the
wheels may come into contact with the
body or the axle components when heavily
loaded or when driving with snow chains.
This could result in damage to the tyres or
the vehicle.
! Retreaded tyres are neither tested nor
recommended by Mercedes-Benz, since
previous damage cannot always be detec-
ted on retreaded tyres. As a result,
Mercedes-Benz cannot guarantee vehicl e
safety if retreaded tyres are fitted. Do not
fit used tyres if you have no information
about their previous usage. G
Risk of accident
If wheels or tyres other than those which
have been tested are fitted:
R the brakes or chassis components could
be damage d
R wheel and tyre clearances can no longer
be guarantee d
This could cause an accident .
Modification work on the brake system and
wheels is not permitted, nor is the use of
spacer plates or brake dust shields. This inva-
lidates the General Operating Permit for the
vehicle. Notes on selecting, fitting and replacing
tyres R
Only fit tyres and wheels of the same type
and make.
R Only fit tyres of the correct size onto the
wheels.
R After fitting new tyres, run them in at mod -
erate speeds for the first 100 km as they
only reach their full performance after this
distance.
R Fit new tyres on the front wheels first if
tyres of the same size are required on the
front and rear wheels.
R Replace the tyres after six years at the lat -
est, regardless of wear. This also applies to
the spare wheel.
R Do not drive with tyres which have too little
tread depth as this significantly reduce s
the traction on wet roads (aquaplaning).
! Store tyres that are not being used in a
cool, dry and preferably dark place. Protect
the tyres against oil, grease, petrol and die-
sel . Notes on regularly inspecting wheels
and tyre
s R
Regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bumps on tyres and deforma-
tion, cracks or severe corrosion on wheels),
at least every 14 days, as well as after off -
road trips or after travelling on rough roads.
Damaged wheels could cause a loss of tyre
pressure.
R Regularly check the tyre tread depth and
the condition of the tread across the whol e
width of the tyre (Y page 212). If neces-
sary, turn the front wheels to full lock in
order to inspect the inner side of the tyre
surface.
R All wheels must have a valve cap to protect
the valve against dirt and moisture.
R Regularly check the pressure of all your
tyres (including the spare tyre*), particu-
larly prior to long trips, and correct th e
pressure as necessary (Y page 213).
Notes on driving R
While driving, pay attention to vibrations,
noises and unusual handling characteris-
tics, e.g. pulling to one side. This may indi- Operation

Notes on care
Regular and proper care maintains the value
of your vehicle.
i It is advisable to use Mercedes-Benz care
products.
Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit a qualified spe-
cialist workshop immediately, e.g. a
Mercedes-Benz Service Centre.
Repair damage caused by loose chippings
and remove the following substances imme-
diately, whilst avoiding rubbing too hard:
R Soak insect remains with insect remover
and rinse off afterwards .
R Soak bird droppings with water and rins e
off afterwards.
R Remove tree resin, oils, fuels and grease by
rubbing gently with a cloth soaked in clean-
ing or lighter fluid .
R Use silicone remover to remove wax.
R Use tar remover to remove tar stains. H
Environmental not
e
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally-responsible manner.
! Do not affix :
R stickers
R films
R magnetic plates or similar
to painted surfaces, otherwise you could
damage the paintwork. Vehicle care
! Do not park the vehicle for a long perio d
of time directly after cleaning, especially if
the wheels have just been cleaned with a
wheel cleaner. Wheel cleaners could cause
rapid corrosion of the brake discs and
brake pads/linings. After cleaning, park
the vehicle when it is at normal operatin g
temperature.
Automatic car wash You can wash the vehicle in an automatic car
wash from the very start,!
Do not use high pressure car wash sys-
tems. The strong water jet could damage
painted parts or attachments.
! Do not use a brush-free automatic car
wash that uses chemical agents to wash
the vehicle.
but preferably one without brushes.
If the vehicle is very dirty, prewash it befor e
cleaning it in an automatic car wash.
! Make sure that the automatic car wash is
suitable for the size of the vehicle. Fold in
the exterior mirrors before the vehicle is
washed. There is otherwise a risk of dam-
age to the exterior mirrors.
! Make sure the side windows are com-
pletely closed, the ventilation/heater
blower is fully turned off and the wind-
screen wiper switch is set to 0. The rai n
sensor may otherwise be activated, for
instance, leading to inadvertent wiper
sweeps being triggered. This could cause
damage to the vehicle.
After using an automatic car wash, wipe off
wax from the windscreen and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the wind-
screen. Operation

X Clean the sensors in the bumper wit h
water, car shampoo and a soft cloth.
! Do not use dry, coarse or hard cloths and
do not scrub. You will otherwise scratch or
damage the sensors. If you intend to use a
high-pressure cleaner or a steam cleaner to
clean the sensors, observe the instructions
issued by the equipment manufacturer concerning the distance to be maintained
between the nozzle of the high-pressure
cleaner and the vehicle. Trailer coupling*
The ball coupling must be cleaned if it
becomes dirty or corroded.
X Remove any rust using a wire brush.
X Remove dirt with a clean, lint-free cloth or
a brush.
! Do not clean the ball coupling with a high -
pressure cleaner. Do not use solvents.
