Rsolvents
R cleaning agents containing solvents
Do not scrub.
Do not touch the surfaces or protective
films with hard objects, e.g. a ring or ice
scraper. You could otherwise scratch or
damage the surfaces and protective film.HEnvironmental note
Dispose of empty packaging and cleaning
cloths in an environmentally responsible
manner.
! Do not park the vehicle for an extended
period right 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. Generally, park the
vehicle at operating temperature after
cleaning.
Exterior care
Automatic car wash
GWarning!
Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, you must drive particularly
carefully after washing the vehicle until the
brakes have dried.
You can wash the vehicle in an automatic car
wash from the very start.
! Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! In car washes with a towing mechanism,
make sure that the automatic transmission
is in transmission position N, otherwise the
vehicle could be damaged.
R Vehicles with a SmartKey:
Do not remove the SmartKey from the
ignition lock. Do not open the driver's
door or front-passenger door when the
engine is switched off. Otherwise, the
automatic transmission selects park
position P automatically and locks the
wheels. You can prevent this by shifting
the automatic transmission to N
beforehand.
R Vehicles with KEYLESS-GO:
Do not open the driver's door or front-
passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position P
automatically and locks the wheels.
Observe the following to make sure that the
automatic transmission stays in position N:XMake sure the vehicle is stationary and the
ignition is switched off.XTurn the SmartKey to position
2 (Y page 149) in the ignition lock.
Use the SmartKey instead of the Start/
Stop button on vehicles with KEYLESS-GO.XDepress and hold the brake pedal.XShift the automatic transmission to
position N.XRelease the brake pedal.XRelease the parking brake.XSwitch off the ignition and leave the
SmartKey in the ignition lock.
! Make sure that the side windows are
completely closed, that the ventilation/
heating is switched off and that the
windshield wiper switch is set to 0.
Otherwise, the rain/light sensor could be
activated, triggering unintended wiper
movements. This can cause damage to the
vehicle.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the
windshield.

to painted surfaces. You could otherwise
damage the paintwork.
If water no longer forms "beads" on the
painted surface, paint care products should
be used that have been approved and
recommended by Mercedes-Benz. This is the
case approximately every three to five
months, depending on climatic conditions
and the care product used.
If dirt has entered the paint surface or the
paintwork has become dull, a paint cleaner
should be used that has been approved and
recommended by Mercedes-Benz.
Never use such care products in direct
sunlight or on a hot hood.XUse a suitable touch-up stick, e.g. MB
Touch Up stick, for quick, temporary repair
of damaged paintwork.

otherwise move and injure you.
XClean the inside and outside of the
windows with a damp cloth and a cleaning
agent that is recommended and approved
by Mercedes-Benz.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing
solvents to clean the inside of the windows.
Do not use hard objects to clean the insides
of the windows, e.g. an ice scraper or ring.
There is otherwise a risk of damaging the
windows.
! Clean the water drainage channels of the
windshield and the rear window at regular
intervals. Under certain circumstances,
deposits such as leaves, petals and pollen
may prevent water from draining away,
leading to corrosion damage.

do not rub them too hard. Otherwise, the
graphite coating could be damaged. This
could cause wiper noise.
XFold the wiper arms away from the
windshield.XCarefully clean the wiper blades with a
damp cloth.XFold the windshield wipers back again
before switching on the ignition.
! Hold the wiper arm securely when folding
back. The windshield could be damaged if
the wiper arm smacks against it suddenly.
Cleaning the headlamps
XClean the plastic lamp lenses on the
headlamps using a wet sponge and a mild

Raising the vehicle
GWarning
When jacking up the vehicle, only use the jack
which has been specifically approved by
Mercedes-Benz for your vehicle.
The jack is designed exclusively for jacking up
the vehicle at the jacking points built into both
sides of the vehicle. The jack saddle must be
placed centrally under the jacking point. The
jack must always be vertical when in use,
especially on inclines or declines.
The jack is intended only for lifting the vehicle
briefly for wheel changes. It is not suited for
performing maintenance work under the
vehicle. To help avoid personal injury, use the
jack only to lift the vehicle during a wheel
change.
Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under the
vehicle.
Always firmly engage the parking brake and
block the wheels with wheel chocks or other
sizable objects before raising the vehicle with
the jack. Do not disengage the parking brake
while the vehicle is raised.
Make sure that the ground on which the
vehicle is standing and where you place the
jack is solid, level and not slippery. If
necessary, use a large underlay. On slippery
surfaces, such as tiled floors, you should use
a non-slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
as a jack underlay. Otherwise, the jack may
not be able to achieve its load-bearing
capacity if it is not at its full height.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.
XUsing lug wrench :, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the bolts
completely.
The jacking points for the jack are located
behind the wheel housings of the front wheels
and in front of the wheel housings of the rear
wheels (arrows).
GWarning
The jack is designed exclusively for jacking up
the vehicle at the jacking points. The jack
saddle must be placed centrally under the
jacking point.
If you do not position the jack correctly in the
jacking point, the vehicle can fall off the jack
and seriously or fatally injure you or others.
! The jack is designed exclusively for
jacking up the vehicle at the jacking points.
Otherwise, your vehicle could be damaged.
XTake ratchet ring spanner out of the vehicle
tool kit and place it on the hexagon nut of
the jack so that the letters AUF are visible.Flat tire303Roadside AssistanceBA 251 USA, CA Edition A 2011; 1; 3, en-USd2sboikeVersion: 3.0.3.52010-04-16T14:31:55+02:00 - Seite 303Z
