Checking the coolant level G
WARNING
The cooling system is pressurised, particu-
larly when the engine is warm. If you open the cap, you could be scalded if hot coolant
sprays out. There is a risk of injury.
Let the engine cool down before you open the
cap. Wear gloves and eye protection. Open
the cap slowly to release the pressure.
! The coolant level must only be checked and
corrected when the engine has cooled down
(coolant temperature under 40 †). Checking
the coolant level when the coolant tempera-
ture is over 40 † can lead to damage to the
engine or engine cooling system. X
Park the vehicle on a level surface.
Only check the coolant level when the vehicle
is on a level surface and the drive system has
cooled down.
X Turn the key to position 2in the ignition lock
(Y page 126).
X Check the coolant temperature display in the
instrument cluster.
The coolant temperature must be below
40 †.
X Turn the key to position 0in the ignition lock
(Y page 126).
X Slowly turn cap :anti-clockwise to allow
excess pressure to escape.
X Turn cap :further anti-clockwise and
remove it.
If the coolant is at the level of marker bar =
in the filler neck when cold, there is enough
coolant in coolant expansion tank ;.240
Engine compartmentMaintenance and care

Damaged seals or electrical components can
lead to leaks or failures.
Cleaning the paintwork !
Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Scratches, corrosive deposits, areas affected by
corrosion and damage caused by inadequate
care cannot always be completely repaired. In
such cases, visit a qualified specialist workshop.
X Remove impurities immediately, where pos-
sible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover and
rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse off
the treated areas afterwards.
X Remove coolant, brake fluid, tree resins, oils,
fuels and greases by rubbing gently with a
cloth soaked in petroleum ether or lighter
fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
Care and treatment of matt paintwork !
Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork shiny.
! The following may cause the paint to
become shiny and thus reduce the matt
effect:
R vigorous rubbing with unsuitable materials
R frequent use of car washes
R washing the vehicle in direct sunlight
! Never use paint cleaner, buffing or polishing
products, or gloss preserver, e.g. wax. These
products are only suitable for high-gloss sur-
faces. Their use on vehicles with matt 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. Observe these notes if your vehicle has a clear
matt finish. This will help you to avoid damage to
the paintwork due to incorrect treatment.
These notes also apply to light-alloy wheels witha clear matt finish.
The vehicle should preferably be washed by
hand using a soft sponge, car shampoo and
plenty of water.
Use only insect remover and car shampoo from
the range of approved Mercedes-Benz care
products. Cleaning vehicle parts
Cleaning the wheels G
WARNING
The water jet of circular-jet nozzles (dirt grind- ers) can cause damage not visible from the
outside to tyres or chassis components. Com-
ponents damaged in this way can unexpect-
edly fail. There is a risk of an accident.
Do not use high-pressure cleaners with circu-
lar-jet nozzles to clean the vehicle. Have dam- aged tyres or chassis components replaced
immediately.
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
! 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 a few minutes after cleaning. Braking heats the brake discs and the brake
pads/linings, thus drying them. The vehicle
can then be parked up.
Cleaning the windows G
WARNING
If the windscreen wipers are set in motion
when cleaning the windscreen or wiper
blades, you could become trapped. There is a danger of injury. 244
CareMaintenance and care

Always switch off the windscreen wipers and
the ignition before cleaning the windscreen or wiper blades.
! Only fold the windscreen wipers away from
the windscreen when vertical. Otherwise, you
will damage the bonnet.
! Do not use dry cloths, abrasive products,
solvents or cleaning agents containing sol-
vents 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
windscreen and the rear window at regular
intervals. Deposits such as leaves, petals and pollen may under certain circumstances pre-
vent water from draining away. This can lead
to corrosion damage and damage to elec-
tronic components.
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.
Cleaning the wiper blades G
WARNING
If the windscreen wipers are set in motion
when cleaning the windscreen or wiper
blades, you could become trapped. There is a danger of injury.
Always switch off the windscreen wipers and
the ignition before cleaning the windscreen or wiper blades.
! Only fold the windscreen wipers away from
the windscreen when vertical. Otherwise, you
will damage the bonnet.
! Do not pull on 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 graph- ite coating could be damaged. This could
cause wiper noise.
! Hold the wiper arm securely when folding
back. The windscreen could be damaged if
the wiper arm hits against it suddenly. X
Fold the wiper arms away from the wind-
screen.
X Clean the wiper blades carefully using a damp
cloth.
X Fold the windscreen wipers back again before
switching on the ignition.
Cleaning the exterior lighting !
Only use cleaning agents or cleaning cloths
that are suitable for plastic lenses. Unsuitable
cleaning agents or cleaning cloths could
scratch or damage the plastic lenses of the
exterior lighting.
X Clean the plastic lenses of the exterior light-
ing using a wet sponge and a mild cleaning
agent, e.g. Mercedes-Benz car shampoo or
cleaning cloths.
Cleaning the mirror turn signal !
Only use cleaning agents or cleaning cloths
that are suitable for plastic lenses. Unsuitable
cleaning agents or cleaning cloths could
scratch or damage the plastic lenses of the
mirror turn signals.
X Clean the plastic lenses of the mirror turn sig-
nals in the exterior mirror housing using a wet sponge and mild cleaning agent, e.g.
Mercedes-Benz car shampoo or cleaning
cloths.
Cleaning the sensors !
If you clean the sensors with a high-pressure
cleaner, make sure that you keep a distance
of at least 30 cm between the vehicle and the high-pressure cleaner nozzle. Information
about the correct distance is available from
the equipment manufacturer. Care
