292 OperationEngine compartmentBe careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.
Screw filler cap1 back on filler neck.
For more information on engine, see the
“Technical data” section (
page 429) and
(
page 431).
Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Center
check the automatic transmission.Active Body Control* (ABC*) fluid level
Regular fluid level check is not required. If
you notice fluid leaks or malfunction mes-
sages in the multifunction display, have an
authorized Mercedes-Benz Center check
the ABC-system.
Coolant level
The engine coolant is a mixture of water
and anticorrosion/antifreeze.
When checking the coolant level,
the vehicle must be parked on level
ground, and
the engine must be cool.
!Excess oil must be siphoned or drained
off. It could cause damage to the en-
gine and catalytic converter not cov-
ered by the Mercedes-Benz Limited
Warranty.

330 OperationVehicle careCleaning and care of vehicle
In operation, even while parked, your vehi-
cle is subjected to varying external influ-
ences which, if gone unchecked, can
attack the paintwork as well as the under-
body and cause lasting damage.Such damage is caused not only by ex-
treme and varying climatic conditions, but
also by:
Air pollution
Road salt
Tar
Gravel and stone chipping
To avoid paint damage, you should imme-
diately remove:
Grease and oil
Fuel
Coolant
Brake fluid
Bird droppings
Insects
Tree resins, etc.
Frequent washing reduces and/or elimi-
nates the aggressiveness and potency of
the above adverse influences.More frequent washings are necessary to
deal with unfavorable conditions:
near the ocean
in industrial areas (smoke, exhaust
emissions)
during winter operation
You should check your vehicle from time to
time for stone chipping or other damage.
Any damage should be repaired as soon as
possible to prevent corrosion.
In doing so, do not neglect the underbody
of the vehicle. A prerequisite for a thor-
ough check is a washing of the underbody
followed by a thorough inspection. Dam-
aged areas need to be re-undercoat-
ed.Your vehicle has been treated at the
factory with a wax-base rustproofing in the
body cavities which will last for the lifetime
of the vehicle. Post-production treatment
is neither necessary nor recommended by
Mercedes-Benz because of the possibility
of incompatibility between materials used
in the production process and others ap-
plied later.
Warning!
G
Many cleaning products can be hazardous.
Some are poisonous, others are flammable.
Always follow the instructions on the partic-
ular container. Always open your vehicle’s
doors or windows when cleaning the inside.
Never use fluids or solvents that are not de-
signed for cleaning your vehicle.

What to do if …?
When the message
ADD 1.0 QT. ENGINE
OIL AT FILLING STATION
(Canada:
1 Liter
) appears while the engine is run-
ning and at operating temperature, the en-
gine oil level has dropped to approximately
the minimum level.When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.
Visually check for oil leaks. If no obvious oil
leaks are noted, drive to the nearest ser-
vice station where the engine oil should be
topped to the required level with an ap-
proved oil specified in the Factory Ap-
proved Service Products pamphlet.

Replacing bulbs
Notes on bulb replacement
Only use 12 volt bulbs of the same type
and with the specified watt rating.
Switch lights off before changing a bulb
to prevent short circuits.
Always use a clean lint-free cloth when
handling bulbs.
Your hands should be dry and free of oil
and grease.
If the newly installed bulb does not
come on, visit an authorized
Mercedes-Benz Center.Have the LEDs and bulbs for the following
lamps replaced by an authorized
Mercedes-Benz Center.
Additional turn signal lamps in the exte-
rior rear view mirrors
Bi-Xenon lamps*
High mounted brake lamp
Brake lamps
Rear side marker lamps
Rear parking lamps
Warning!
G
Keep bulbs out of reach of children.
Bulbs and bulb sockets can be very hot. Al-
low the lamp to cool down before changing
a bulb.
Halogen lamps contain pressurized gas. A
bulb can explode if you:
touch or move it when hot
drop the bulb
scratch the bulb
Wear eye and hand protection.
Because of high voltage in Xenon lamps, it is
dangerous to replace the bulb or repair the
lamp and its components. We recommend
that you have such work done by a qualified
technician.
iHave the headlamp adjustment
checked regularly.
