Otherwise, you could damage the paint fin-
ish or plastic. H
Environmental note
Dispose of empty packaging, cleaning cloths
and polishing wads in an environmentally
responsible manner. Vehicle care
! Do not park the vehicle for a long period
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 operating
temperature.
Automatic car wash You can wash the vehicle in an automatic car
wash from the beginning.
! Do not use a touch-free automatic car
wash that uses chemical agents to wash
the vehicle.
Preferably use automatic car washes without
brushes.
If the vehicle is very dirty, pre-wash it before
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 that the automatic transmis-
sion is not in position Pwhen washing your
vehicle in a tow-through car wash.
Do not remove the key from the ignition
lock. Do not open the driver's or front-
passenger door when the engine is
switched off, as this automatically shifts
the automatic transmission to park posi-
tion Pand locks the wheels, unless you
have previously shifted the automatic
transmission to N.
! Make sure that the side windows are com-
pletely closed, that the ventilation/heater
blower is fully turned off and that the wind-
screen wiper switch is set to 0. Otherwise,
the rain sensor may be activated, triggering
unintended wiper movements. This could
cause damage to the vehicle.
After using an automatic car wash, wipe off
wax and drying agents from the windscreen
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windscreen.
High-pressure cleaners G
Risk of accident
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clean your
vehicle, in particular the tyres. Otherwise, you
could damage the tyres and cause an acci-
dent.
! 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 (at least 30 cm).
Move the high-pressure cleaner nozzle
around when cleaning your vehicle. 168 CareOperation

as this will result in damage to the graphite
coating. This could cause wiper noise.
X Turn the key to position 1(Y page 61)in the
ignition lock.
X Set the windscreen wipers to position °
(Y page 79) on the combination switch.
X Turn the key to position 0(Y page 61) or
remove it when the wiper arms are vertical.
! Only fold the windscreen wipers away
from the windscreen when vertical. Other-
wise, you will damage the bonnet.
X Fold the wiper arms away from the wind-
screen.

Clean the inside of the windscreen, rear
and side windows using a damp cloth and
commercially-available glass cleaner.
Avoid touching the inside of the rear win-
dow and the side windows with hard
objects, e.g. ice scrapers or rings. Other-
wise, you could cause damage to the rear
window heating or the aerial in the rear
window and the side windows.
i Anti-glare film retrofitted to the inside of
the rear or side windows could interfere
with radio or mobile phone reception, espe-
cially if it is conductive or metal-coated
film. Information about anti-glare film can
be obtained from any Mercedes-Benz
Service Centre.

Otherwise, you could scratch or damage
the surface of the lenses.
Cleaning the panorama sliding sun-
roof* A protective film is laminated to the rear glass
element of the panorama sliding sunroof.
! Do not use any of the following to clean
the protective film:
R dry cloths
R abrasive cleaning agents
R solvents
R cleaning agents containing solvent
Do not touch the protective film with hard
objects, e.g. ice scrapers or rings. Other-
wise, you could scratch or damage the sur-
face of the protective film.
Cleaning the plastic trim !
Do not use dry, coarse or hard cloths and
do not scrub. Doing so will scratch or dam-
age the surfaces.
! Ensure that cosmetics and suntan lotion
do not come into contact with the vehicle's
trim. This will protect the vehicle's high-
quality trim and help retain its overall
appearance.
X Wipe plastic parts with a damp, lint-free
cloth (e.g. a microfibre cloth).
X Light soiling: use a low-foaming soap (e.g.
a light liquid hand soap) diluted in water.
X Heavy soiling: use a cleaning agent that is
solvent-free and non-corrosive. Mercedes-
Benz recommends that you use a
Mercedes-Benz cleaning product for this
purpose. Cleaning the steering wheel boss and
dashboard X
Moisten a clean lint-free cloth with water.
X Clean the plastic parts and the dashboard.
X If particularly dirty, use a mild detergent. G
Risk of injury
Do not use cleaners and cockpit care sprays
containing solvents to clean the cockpit and
steering wheel boss. Cleaners containing sol-
vents cause the surface to become porous
and in the event of an airbag being triggered,
plastic parts that have become loose could
cause considerable injuries.
Cleaning the COMAND display X
When cleaning the display, make sure that
it is switched off and has cooled down.
X Clean the display's surface with a conven-
tional micro-fibre cloth and cleaning agent
for TFT/LCD displays.

R alcohol-based thinner or petrol
R abrasive cleaning agents
R conventional household cleaning agents
These can damage the display's surface.
Do not press the display's surface during
cleaning: this could lead to irreversible
damage.
Cleaning the seat covers !
Do not use a microfibre cloth to clean
genuine leather and artificial leather cov-
ers, as it is too aggressive and, if used
often, may damage the cover.
! You should clean:
R genuine leather covers using a damp
cloth, then wipe the covers down using a
dry cloth. Make sure that the leather 170 CareOperation

moistened with a solution containing 1%
detergent (e. g. washing-up liquid). When
cleaning, take care not to rub too vigo-
rously and always wipe entire seat sec-
tions to avoid leaving visible lines. Leave
the seat to dry afterwards. Cleaning
results depend on the type of dirt and
how long it has been there.
i Note that leather covers are a natural
product and, as such, are subject to a nat-
ural ageing process and may react differ-
ently (e.g. increased wrinkling) to certain
environmental influences (such as high
humidity, intense heat).
Note that regular care is essential to ensure
that the quality (both appearance and com-
fort) of the covers is retained over time.

grit and corrosive environmental factors may
cause flash rust to form on the surface.
Regular care of the exhaust tail pipes will
ensure that their original shine is restored. !
Do not clean the exhaust tail pipes with
alkaline-based cleaning agents such as
wheel cleaner.
Use the chrome-cleaning agent recommen-
ded by Mercedes-Benz for cleaning. Infor-
mation about chrome-cleaning agents can
