Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment. G
WARNING
If engine oil comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any engine oil on hot
engine parts. Example: engine oil cap
X
Turn cap :anti-clockwise and remove it.

Fill carefully to the maximum mark on the oil
dipstick.
i Depending on the engine, the difference
between the minimum mark and the maxi-
mum mark is approximately 1.5 –2litres.
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.

MaintenanceMaintenance and care

Use care products and cleaning agents rec-
ommended and approved by Mercedes-Benz.
! For cleaning your vehicle, do not use any
of the following:
R dry, rough or hard cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. aring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film. H
Environmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible man-
ner.
! Do not park up the vehicle for an extended
period straight after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for afew minutes after clean-
ing. Braking heats the brake discs and the
brake pads/linings, thus drying them. The
vehicle can then be parked up. Care of the exterior
Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, following acar wash, drive with
particular care until the brakes are dry. G
WARNING
The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function and DISTRONIC PLUS before the vehicle is washed in an auto-
matic car wash.
You can wash the vehicle in an automatic car
wash from the very start.
! We recommend automatic car washes
with an adjustable 21
high-pressure pre-
cleaning program. In car washes that use
high water pressures, there is adanger that
as mall quantity of water may leak into the
vehicle.
! Cabriolet: do not treat the vehicle with
hot wax under any circumstances.
! Cabriolet: pull the key out of the ignition
lock when washing the vehicle. This
ensures that the wind deflector on the
windscreen is retracted. The wind deflector
may otherwise be damaged.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic transmis-
sion is in position Nwhen washing your
vehicle in atow-through car wash. The vehi-
cle could be damagedift he transmission is
in another position.
! Make sure that:
R the side windows and sliding sunroof or
soft top are closed completely.
R the blowerf or the ventilation/heatin gis
switched off (OFF button is depressed).
R the windscreen wiper switch is at posi-
tion 0.
The vehicle could otherwise be damaged.
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.
