Important safety notes
GWARNING
Certain components in the engine compart-
ment, such as the engine, radiator and parts
of the exhaust system, can become very hot.
Working in the engine compartment poses a
risk of injury.
Where possible, let the engine cool down and touch only the components described in the
following.

ignite. There is a risk of fire and injury.
Make sure that engine oil is not spilled next to
the filler neck. Let the engine cool down and
thoroughly clean the engine oil off the com-
ponents before starting the engine.
General notes
Depending on your driving style, the vehicle
consumes up to 0.9 US qt (0.8 liters) of oil per
600 miles (1,000 km). The oil consumption may
be higher than this when the vehicle is new or if
you frequently drive at high engine speeds.
Depending on the engine, the oil dipstick may be
in a different location.
When checking the oil level:
Rpark the vehicle on a level surface.
Rthe engine should be switched off for approx-
imately five minutes if the engine is at normal
operating temperature.
Rall vehicles (except Mercedes-AMG C 63/C
63S): the engine is not at normal operating
temperature, e.g. if the engine was only star-
ted briefly, wait approximately 30 minutes
before carrying out the measurement.
The oil level of the Mercedes-AMG C 63/C63 S
must only be checked when the engine is at
normal operating temperature.

Cleaning the vehicle parts
Cleaning the wheels
GWARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisible exterior damage
to the tires or chassis components. Compo-
nents damaged in this way may fail unexpect-
edly. There is a risk of an accident.
Do not use power washers with circular jet
nozzles to clean the vehicle. Have damaged
tires or chassis components replaced imme-
diately.
!Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
!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.
Cleaning the windows
GWARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
!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
windshield 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.
XClean the inside and outside of the windows
with a damp cloth and a cleaning product that
is recommended and approved by Mercedes-
Benz.
Cleaning wiper blades
GWARNING
You could become trapped by the windshield wipers if they start moving while cleaning the
windshield or wiper blades. There is a risk of
injury.
Always switch off the windshield wipers and
the ignition before cleaning the windshield or
wiper blades.
!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 graph-
ite coating could be damaged. This could
cause wiper noise.
!Hold the wiper arm securely when folding
back. The windshield could be damaged if the
wiper arm smacks against it suddenly.
XFold the windshield wiper arms away from the
windshield (Ypage 126).
XCarefully clean the wiper blades with a damp
cloth.
XFold the windshield wiper arms back again
before switching on the ignition.
Cleaning the exterior lighting
!Only use cleaning agents or cleaning cloths
which are suitable for plastic light lenses.

could scratch or damage the plastic light len- ses.
XClean 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.
338Care
Maintenance and care

Cleaning the exhaust pipes
GWARNING
The exhaust tail pipe and tail pipe trim can
become very hot. If you come into contact
with these parts of the vehicle, you could burn
yourself. There is a risk of injury.
Always be particularly careful around the
exhaust tail pipe and the tail pipe trim. Allow
these components to cool down before touch-
ing them.
!Do not clean the exhaust pipe with acid-
based cleaning agents, such as bathroom
cleaner or wheel cleaner.
!Mercedes-AMG vehicles with black exhaust
pipes: the black-chrome tailpipe finishers
should not be polished with a chrome polish.
They will otherwise lose their black sheen. For
optimal care, the faceplates should be rubbed with a lightly oiled cloth after every car wash.
Commercially available engine and care oils
are suitable for this.
For heavier soiling, you can apply a fine paint-
work polish with a microfiber cloth. Remove
the excess polish residue after polishing.
Impurities combined with the effects of road grit
and corrosive environmental factors may cause
flash rust to form on the surface. You can
restore the original shine of the exhaust pipe by
cleaning it regularly, especially in winter and
after washing.
XClean the exhaust pipe with a care product
tested and approved by Mercedes-Benz.
Interior care
Cleaning the display
!For cleaning, do not use any of the following:
Ralcohol-based thinner or gasoline
Rabrasive cleaning agents
Rcommercially-available household cleaning
agents
These may damage the display surface. Do
not put pressure on the display surface when cleaning. This could lead to irreparable dam-
age to the display.
XBefore cleaning the display, make sure that it
is switched off and has cooled down.
XClean the display surface using a commer-
cially available microfiber cloth and TFT/LCD
display cleaner.
XDry the display surface using a dry microfiber
cloth.
Cleaning the plastic trim
GWARNING
Care products and cleaning agents containing solvents cause surfaces in the cockpit to
become porous. As a result, plastic parts may
come loose in the event of air bag deploy-
ment. There is a risk of injury.
Do not use any care products and cleaning
agents to clean the cockpit.
!Do not affix the following to plastic surfaces:
Rstickers
Rfilms
Rscented oil bottles or similar items
You can otherwise damage the plastic.
!Do not allow cosmetics, insect repellent or
sunscreen to come into contact with the plas-
tic trim. This maintains the high-quality look of
the surfaces.
XWipe the plastic trim with a damp, lint-free
cloth, e.g. a microfiber cloth.
XHeavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
The surface may change color temporarily.
Wait until the surface is dry again.
Cleaning the steering wheel and gear or
selector lever
XThoroughly wipe with a damp cloth or use
leather care agents that have been recom-
mended and approved by Mercedes-Benz.
Cleaning genuine wood and trim ele-
ments
!Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners, polishes

or waxes. There is otherwise a risk of damag-
ing the surface.
!Do not use chrome polish on trim pieces.
The trim pieces have a chrome look but are
mostly made of anodized aluminum and can
lose their shine if chrome polish is used. Use
a damp, lint-free cloth instead when cleaning
the trim pieces.
If the chrome-plated trim pieces are very
dirty, you can use a chrome polish. If you are unsure as to whether the trim pieces are
chrome-plated or not, consult an authorized
Mercedes-Benz Center.
XWipe the wooden trim and trim pieces with a
damp, lint-free cloth, e.g. a microfiber cloth.
XTrim elements with piano black finish:
clean with a soft, damp cloth and a commer-
cially available soap solution.
XHeavy soiling: use care and cleaning prod-
ucts recommended and approved by
Mercedes-Benz.
Cleaning the seat covers
General notes
!Do not use a microfiber cloth to clean covers
made out of real leather, artificial leather or
DINAMICA. If used often, these can damage
the cover.
Note that regular care is essential to ensure that
the appearance and comfort of the covers is
retained over time.
Genuine leather seat covers
!To retain the natural appearance of the
leather, observe the following cleaning
instructions:
RClean genuine leather covers carefully with a damp cloth and then wipe the covers
down with a dry cloth.
RMake sure that the leather does not
become soaked. It may otherwise become
rough and cracked.
ROnly use leather care agents that have
been tested and approved by Mercedes-
Benz. You can obtain these from a qualified
specialist workshop.
Leather is a natural product.
It exhibits natural surface characteristics, for
example:
Rdifferences in the texture
Rmarks caused by growth and injury
Rslight nuances of color
These are characteristics of leather and not
material defects.
