Adding engine oil H
Environmental note
When topping up the oil, take care not to spill
any. If oil enters the soil or waterways, it is
harmful to the environment. G
WARNING
If engine oil comes into contact with hot
engine parts, it may ignite and you could burn
yourself. Do not spill any engine oil on hot
engine parts. Example: engine oil cap
X
Turn cap :anti-clockwise and remove it.
X Top up with the amount of oil required.
Fill carefully to the maximum mark on the oil
dipstick.
i Depending on the engine, the difference
between the minimum mark and the maxi-
mum mark is approximately 1.5 –2litres.
! Do not add too much oil. If the oil level is
above the "max" mark on the dipstick, too
much oil has been added. This can lead to
damage to the engine or the catalytic con-
verter. Have excess oil siphoned off.
For further information on engine oil, see
(Y page 335). X
Replace cap :on the filler neck and

Checking the coolant level Only check the coolant level when the vehicle
is on alevel surface and the engine has cooled
down.
X Turn the key to position 2(Y page 147) in

On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 147).
X Check the coolant temperature displayin

WARNING
The cooling system is pressurised. Therefore,
only unscrew the cap once the engine has
cooled down. The coolant temperature gauge
must display less than 70 †.Otherwise, you
could be scalded if hot coolant escapes. X

Notes on care
Regular care of your vehicle is acondition for
retaining the quality in the long term. Care
285Maintenance and care Z

High-pressure cleaning equipment
G
WARNING
Do not use high-pressure cleaners with circu-
lar-jet nozzles (dirt grinders) to clea nyour
vehicle, in particular the tyres. You could oth-
erwise damage the tyres and cause an acci-
dent.
! Always maintain adistance of at least
30 cm between the vehicle and the high-
pressure cleaner nozzle. Information about
the correc tdistanc eisavailable fro mthe
equipment manufacturer.
Move the high-pressure cleaner nozzle
around when cleaning your vehicle.
Do not aim directly at any of the following:
R tyres
R door gaps, jointse tc.
R soft top (Cabriolet)
R wind deflector net (Cabriolet)
R electrical components
R battery
R connectors
R lights
R seals
R trim elements
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
Cleaningt he wheels !
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 afew minutes after clean-
ing. Braking heats the brake discs and the brake pads/linings, thus drying them. The
vehicle can then be parked up.
Cleaningt he paintwork Scratches, corrosive deposits, areas affected
by corrosion and damage caused by inade-
quate care cannot always be completely
repaired. In such cases, visit aqualified spe-
cialist workshop, e.g. aMercedes-Benz
Service Centre.
X Remove impurities immediately, where
possible, 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 resin,
oils, fuels and greases by rubbing gently
with acloth soaked in petroleum ether or
lighter fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
! Do not affix:
R stickers
R films
R magnetic plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
Care and treatment of mattp aintwork If your vehicle has
aclear matt 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 aclear matt finish.
! Never polish the vehicle or the light alloy
wheels. Polishing makes the paintwork
shiny. Care
287Maintenance and care Z

!
The following may cause the paint to
become shiny and thus reduce the matt
effect:
R Vigorous rubbing with unsuitablem ate-
rials.
R Frequent use of car washes.
R Washing the vehicle in direct sunlight.
! Never use paint cleaner, buffing or pol-
ishing products, or gloss preserver, e.g.
wax. These products are only suitablef or
high-gloss surfaces. Their use on vehicles
with matt finish leadstoc onsiderable sur-
face damage (shiny, spotted areas).
Alwaysh ave paintwork repairs performed
at aq ualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
! Do not use wash programs with ahot wax
treatment under any circumstances.
i The vehicle should preferably be washed
by hand using asoft sponge, car shampoo
and plenty of water.
i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products.

the direction of the fabric.
! Never use any of the following to clean the
soft top:
R petrol
R thinner
R tar or stain remover
R other organic solvents
! Remove bird droppings immediately as
they are corrosive and, therefore, can make the soft-top fabric leak. Do not use high-
pressure cleanin
gequipment to clean the
vehicle. Do not use sharp-edged equipment
to remove ice and snow.
Frequent cleanin greduces the resistance to
dirt of the soft top.
To restore this resistance to dirt, clean the
soft top using soft top cleanin gagents that
have been recommended and approved by
Mercedes-Benz.
Incorrec tcleanin gand care ,aswell as ageing,
can cause the soft top seams to leak. Have
the soft-top seams sealed at aqualified spe-

you plan to leave the vehicle outside for a
long period of time.

when cleaning. This could lead to irrepara-
ble damage to the display.
Cleaningt he plastic trim G
WARNING
When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as aresult plastic
parts may break away and be thrown around
the interior when an airbag is deployed, which
may result in severe injuries.
! Do not affix the following to plastic surfa-
ces:
R stickers
R films
R scented oil bottles or similar items
You could otherwise damage the plastic. Care
291Maintenance and care Z

!
Do not allowc osmetics, insect repellent
or sunscreen to come in contact with the
plastic trim. This maintains the high-quality
look of the surfaces.
X Wipe the plastic trim with adamp, lint-free
cloth, e.g. amicrofibre cloth.

such as tar remover, wheel cleaners, pol-
ishes or waxes. There is otherwise arisk of
damaging the surface.
Cleaning the seat covers !
Do not use microfibre cloths to clean gen-
uine leather, artificial leather or
Alcantara® covers. If used often, these can
damage the cover.
! Observe the following when cleaning:
R clean genuine leather covers carefully
with adamp cloth and then wipe the cov-
ers down with adry cloth. Make sure that
the leather does not become soaked. It
may otherwise become rough and
cracked. Only use leather care agents

if necessary, restart the tyre pressure loss
warning system or the tyre pressure monitor.
! On vehicles fitted with atyre pressure
monitor, electronic components are loca-

Tyre-fitting tools should not be applied in
the area of the valve, as this could damage
the electronic components.
Always have the tyres changed at aquali-
fied specialist workshop, e.g. aMercedes-

Tyres with aspecified direction of rotation
have additional benefits, e.g. if there is arisk
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.
You may fit an emergency spare wheel/spare
wheel against the direction of rotation.
Observe the time restriction on use as well as
the speed limitation specified on the emer-
gency spare wheel/spare wheel.
