Important safety notes
G
WARNING
The windshield will not longer be wiped
properly if the wiper blades are worn. This
could prevent you from observing the traffic
conditions, thereby causing an accident.
Replace the

wiper blades twice a year, ideally
in spring and fall.
! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield/rear
window can scratch the glass if wiping
takes place when the windshield/rear
window is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always
use washer fluid when operating the
windshield wipers.
! If the windshield wipers leave smears on
the windshield/rear window after the
vehicle has been washed in an automatic
car wash, this may be due to wax or other
residue. Clean the windshield/rear window
with washer fluid after an automatic car
wash. Windshield wipers

windshield using washer fluid
X Turn the SmartKey to position 1 or 2

the windshield wipers may be activated
inadvertently. This could then damage the
windshield wiper blades or scratch the
windshield.
For this reason, you should always switch
off the windshield wipers in dry weather.
In the ° position, the appropriate wiping
frequency is set automatically according to
the intensity of the rain.
Intermittent wiping is interrupted if you stop

Useful information
i This Operator's Manual describes all
models and all standard and optional
equipment of your vehicle available at the
time of publication of the Operator's
Manual. Country-specific differences are
possible. Please
note that your vehicle may
not be equipped with all features
described. This also applies to safety-
related systems and functions.
i Please read the information on qualified
specialist workshops (Y page 20). Engine compartment
Hood
Opening the hood G
WARNING
Do
not pull the release lever while the vehicle
is in motion. Otherwise, the hood could be
forced open by passing air flow.
This could

cause the hood to come loose and
injure you and/or others. G
WARNING
Do not open the hood when the engine is
overheated. You could be seriously injured.
Observe the coolant temperature gauge to
determine whether the engine may be
overheated. If you see flames or smoke
coming from the engine compartment, move
away from the vehicle. Wait until the engine
has cooled. If necessary, call the fire
department. G
WARNING
You
could be injured when the hood is open –
even when the engine is turned off.
Parts of the engine can become very hot. To
prevent burns,

let the engine cool completely
before touching any components on the
vehicle. Comply with all relevant safety
precautions. G
WARNING
To help prevent personal injury, stay clear of
moving parts when the hood is open and the
engine is running.
The radiator fan may continue to run for
approximately 30 seconds or may even
restart after the engine has been turned off.
Stay clear of fan blades. G
WARNING
The engine is equipped with a transistorized
ignition system. Because of the high voltage,
it is dangerous to touch any components
(ignition coils, spark plug sockets, diagnostic
socket) of the ignition system:
R with the engine running
R while starting the engine
R when the ignition is switched on and the
engine is turned manually
X Make sure that the windshield wipers are
switched off. G
WARNING
The windshield wipers and wiper linkage
could be set in motion.
When the hood is open, you or others could
be injured by the wiper linkage.
Make sure that the windshield wipers are
switched off

and that the SmartKey has been
pulled out of the ignition lock before opening
the hood.
The release lever on the hood is in the footwell
on the left-hand side of the vehicle when
viewed in the direction of travel. 210
Engine compartment
Maintenance and care

vehicle's doors or windows when cleaning the
inside.
Never use fluids or solvents that are not
designed for cleaning your vehicle.
Always lock

away cleaning products and keep
them out of reach of children.
! 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. a ring 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
manner.
! Do not park 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 a few minutes after
cleaning. Braking heats the brake discs and
the brake pads/linings, thus drying them.
The vehicle can then be parked. Exterior care
Automatic car wash G
WARNING
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.
! 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. The exterior mirrors could
otherwise be damaged.
! Make sure that the automatic
transmission is in position N when washing
your vehicle in a tow-through car wash. The
vehicle could be damaged if the
transmission is in another position.
! Make sure that:
R the side windows and sliding sunroof are
closed completely.
R the blower for the ventilation/heating is
switched off (airflow control is turned to
position 0/the à and Á buttons
are switched off).
R the windshield wiper switch is at position
0.
The vehicle could otherwise be damaged.
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.
Washing by hand When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
When washing the vehicle underbody, also
clean the inside of the wheels.

Maintenance and care Z

three to five months, depending on the
climate
conditions
and the care product used.
If dirt has penetrated the paint surface or if
the paint has become dull, the paint cleaner
recommended and approved by Mercedes-
Benz should be used.
Do not use these care products in the sun or
on the hood while the hood is hot.
X Use a suitable touch-up stick, e.g. MB
Touch-Up Stick,

to correct smaller areas of
paint damage quickly and provisionally.
Matte finish care If your vehicle has a clear matte finish,
observe
the

following instructions in order to
avoid damage to the paintwork due to
incorrect care.
These notes also apply to light alloy wheels
with a clear matte finish.
! Never polish the vehicle or the light alloy
wheels. Polishing causes the finish to
shine.
! Never use paint cleaner, buffing or
polishing products, or gloss preserver, e.g.
wax. These products are only suitable for
high-gloss surfaces. Their use on vehicles
with matte finish leads to considerable
surface damage (shiny, spotted areas).
Always have paintwork repairs carried out
at a qualified specialist workshop.
! Do not use wash programs with a hot wax
treatment under any circumstances.
i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products.
Cleaning the windows G
WARNING
Switch off the windshield wipers and remove
the SmartKey from the ignition lock before
cleaning the windshield or the wiper blades.
The windshield wipers could otherwise move
and injure you. X
Clean 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 touch the insides of the windows
with hard objects, 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. Deposits such as leaves, petals
and pollen may under certain
circumstances prevent water from draining
away. This can lead to corrosion damage
and damage to electronic components.
Cleaning the wiper blades G
WARNING
Switch off the windshield wipers and remove
the SmartKey from the ignition lock before
cleaning the windshield or the wiper blades.
The windshield wipers could otherwise move
and injure you.
! Do not pull the wiper blade. Otherwise,
the wiper blade could be damaged.
! Do not clean wiper blades too often and
do not rub them too hard. Otherwise, the
graphite coating could be damaged. This
could cause wiper noise.
X Fold the wiper arms away from the
windshield.
X Carefully clean the wiper blades with a
damp cloth.
X Fold 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. Care
