Adding engine oil
G
WARNING
If engine oil comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Make sure that engine oil is no tspilled next
to the filler neck. Let the engine cool down
and thoroughly clean the engine oil off the
components before starting the engine. H
Environmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
! Only use engine oils and oil filters that
have been approved for vehicles with a
service system. You can obtain a list of the
engine oils and oil filters tested and
approved in accordance with the
Mercedes-Benz Specifications for Service
Products at any Mercedes-Benz Service
center.
Damage to the engine or exhaust system is
caused by the following:
R using engine oils and oil filters that have
not been specifically approved for the
service system
R replacing engine oil and oil filters after
the interval for replacemen tspecified by
the service system has been exceeded
R using engine oil additives.
! 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
converter. Have excess oil siphoned off. Example: engine oil cap
X
Turn cap 0002counter-clockwise and remove
it.
X Add engine oil.
If the oil level is at or below the MIN mark
on the oil dipstick, add 1.1 US qt (1.0 liter)
of engine oil.
X Replace cap 0002on the filler neck and turn
clockwise.
Ensure that the cap locks into place
securely.
X Check the oil level agai nwith the oil
dipstick (Y page 513).

Checking coolant level G
WARNING
The engine cooling system is pressurized,
particularly when the engine is warm. When
opening the cap, you could be scalded by hot
coolan tspraying out. There is a risk of injury.
Let the engine cool down before opening the
cap. Wear eye and hand protection when
opening the cap. Open the cap slowly half a
turn to allow pressure to escape. 514
Engine compartmentMaintenance and care

Example
X
Park the vehicle on a level surface.
Only check the coolant level when the
vehicle is on a level surface and the engine
has cooled down.
X Turn the SmartKey to position 2in the
ignition lock (Y page 155).
On vehicles with KEYLESS-GO, press the
Start/Stop button twice (Y page 155).
X Check the coolant temperature gauge in
the multifunctio ndisplay.
The coolan ttemperature must be below
158 ‡ (70 †).
X Turn the SmartKey to position
0(Y page 155) in the ignition lock.
X Slowly turn cap 0003half a turn counter-
clockwise to allow excess pressure to
escape.
X Turn cap 0003further counter-clockwise and
remove it.
If the coolant is at the level of marker bar
0027 in the filler neckw hen cold, there is
enough coolant in coolant expansion
tank 0002.
If the coolant level is approximately 0.6 in
(1.5 cm) above marker bar 0027in the fuel
filler neck when warm, there is enough
coolant in expansion tank 0002.
X If necessary, add coolant that has been
tested and approved by Mercedes-Benz.
X Replace cap 0003and turn it clockwise as far
as it will go.

WARNING
If antifreeze comes into contact with hot
components in the engine compartment, it
may ignite. There is a risk of fire and injury.
Let the engine cool down before you add
antifreeze. Make sure that antifreeze is not
spilled nex tto the filler neck.T horoughly
clean the antifreeze from components before
starting the engine. G
WARNING
Windshield washer concentrate is highly
flammable. If it comes into contact with hot
engine components or the exhaust system it
could ignite. There is a risk of fire and injury.
Make sure that no windshield washer
concentrate is spilled next to the filler neck. Example
X
To open: pull cap0002upwards by the tab.
X Add the premixed washer fluid.
X To close: press cap 0002onto the filler neck
until it engages.
The washer fluid reservoir is used for both the
windshield washer system and the headlamp
cleaning system.

WARNING
The water jet from a circular jet nozzle (dirt
blasters) can cause invisibl eexterior damage
to the tires or chassis components.
Components damaged in this way may fail
unexpectedly .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
immediately.
! Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the power washer nozzle around
when cleaning your vehicle.
Do not aim directly at any of the following:
R tires
R door gaps, roof gaps, joints, etc.
R electrical components
R battery
R connectors
R lights
R seals
R trim
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
! Vehicles with HANDS-FREE ACCESS: if a
SmartKey with KEYLESS-GO is within the
detection range of the KEYLESS-GO
antenna, the following situations could lead
to the unintentional opening of the trunk
lid:
R using a car wash
R using a power washer
Make sure that the SmartKey is at least
6.5 ft (2 m) away from the vehicle. 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 dirt immediately, where possible,
while 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 a cloth soaked in petroleum ether or
lighter fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.
If water no longer forms "beads" on the paint
surface, use the paint care products
recommended and approved by Mercedes-
Benz.T his is the case approximately every
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 repair slight damage to
the paintwork quickly and provisionally. Care
