Risk of injury
The cooling system is pressurised. There-
fore, only unscrew the cap once the engine
has cooled down. 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 level
when the vehicle is on a level surface and the
engine has cooled down. Checking the coolant level The coolant expansion tank is located in the
engine compartment on the right when
viewed in the direction of travel.

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 reduces
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 tyres R
Regularly check the wheels and tyres of
your vehicle for damage (e.g. cuts, punctu-
res, tears, bulges on tyres and deformation,
cracks or severe corrosion on wheels), at
least every 14 days, as well as after driving
off-road or 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 whole
width of the tyre (Y page 178). 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*, particularly
prior to long trips, and correct the pressure
as necessary (Y page 178).
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-
cate that the wheels or tyres are damaged.
If you suspect that a tyre is defective, reduce your speed and stop the vehicle as
soon as possible to check the wheels and
tyres for damage. Hidden tyre damage
could also be causing the unusual handling
characteristics. If you find no signs of dam-
age, have the wheels and tyres examined
at a specialist workshop, for example at a
Mercedes-Benz Service Centre.
R When parking your vehicle, make sure that
the tyres do not get deformed by the kerb
or other obstacles. If it is necessary to drive
over kerbs, speed humps or similar, try to
do so slowly and at an obtuse angle. Oth-
erwise, the tyres, particularly the sidewalls,
could get damaged. Direction of rotation
Tyres with a specified direction of rotation
have additional benefits, e.g. if there is a risk
of aquaplaning. You will only gain these ben-
efits if the correct direction of rotation is
observed.
An arrow on the sidewall of the tyre indicates
its correct direction of rotation.
i You may fit a spare tyre *against the
direction of rotation. 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 rinse
off afterwards.
R Remove tree resin, oils, fuels and greases
by rubbing gently with a cloth soaked in
petroleum ether or lighter fluid.
R Use silicone remover to remove wax.
R Use tar remover to remove tar stains. Operation

Care
193H
Environmental note
Dispose of empty packaging, cleaning
cloths and polishing wads in an environ-
mentally responsible manner.
! Do not affix to painted surfaces or plastic
surfaces:
R stickers
R films
R magnetic plates
R scented oil bottle or similar items
You could otherwise damage the paint fin-
ish or plastic.
! Clean the water drainage channels of the
windscreen and the rear window at regular
intervals. Deposits such as leaves, petals
and pollen may under certain circumstan-
ces prevent water from draining away lead-
ing to corrosion damage. 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 with
high-pressure jets for pre-washing.
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 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. The rain
sensor may otherwise be activated, trig-
gering 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 cir-
cular-jet nozzles (dirt grinders) to clean
your vehicle or ― especially ― the tyres.
Otherwise, you could damage the tyres and
cause an accident.
! 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. Operation

You could otherwise scratch or damage the
surface of the lenses.
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.
! In order to protect the vehicle's high-qual-
ity surfaces and to retain the overall
appearance, avoid contact with cosmetics
and suntan lotion.
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 solvents cause the surface to
become porous and in the event of an air-
bag being triggered, plastic parts that have
become loose could cause considerable
injuries.
Cleaning the leather upholstery* !
Cleaning
R Clean genuine leather covers using a
damp cloth, then wipe the covers down
using a dry cloth. Make sure that the
leather does not become soaked. For
leather care, use leather care foam A 001
986 59 71 10. You can purchase this
from any Mercedes-Benz Service Centre.
R Clean artificial leather covers with a cloth
moistened with a solution containing 1%
detergent (e. g. washing-up liquid).
R Clean fabric covers with a microfibre
cloth moistened with a solution contain-
ing 1% detergent (e. g. washing-up liquid).
When cleaning, take care not to rub too
vigorously and always wipe entire seat
sections to avoid leaving visible lines. Leave the seat to dry afterwards. Clean-
ing results depend on the type of dirt and
how long it has been there.
R Clean Alcantara covers with a damp
cloth. Make sure you wipe entire seat
sections to avoid leaving visible lines.
i Note that leather covers are a natural
product and as such are subject to a natural
ageing process and may react differently
(e.g. increased wrinkling) to certain envi-
ronmental influences (such as high humid-
ity, 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.
Cleaning the trim strips (three-door
vehicles) !
Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents to clean the trim strips below the side
windows. You may otherwise damage the
surface of the trim strips.
Cleaning the padded table* The plastic parts of the padded table can be
cleaned using a detergent solution. Operation
