maintained automatically at a constant level.
The system automatically regulates the
temperature of the dispensed air, the airflow
and the air distribution.
Automatic mode will achieve optimal
operation if cooling with air dehumidification
is also activated. If desired, cooling with air
dehumidification can be deactivated.

! Only use engine oils and oil filters which
have been approved for vehicles with a
service system. A list of the engine oils and
oil filters that have been tested and
approved according to the Mercedes-Benz
specifications for service products can be
found on the Internet at http://
www.mbusa.com (USA only). Further
information on tested and approved engine
oils and oil filters can be obtained from any
authorized Mercedes-Benz Center.
The following causes engine failure or
damage to the exhaust system:
Rusing engine oils and oil filters that are
not specifically approved for the service
system
Rreplacing the engine oil and oil filter after
having exceeded the interval for
replacement prescribed by the
maintenance system
Rusing engine oil additives
Example: engine oil cap
Engine oil cap (G 55 AMG)
XTurn cap : counter-clockwise and remove
it.
XAdd the amount of oil required.
Observe the specifications in the on-board
computer when doing so or fill carefully to the
maximum mark on the oil dipstick.
iThe difference in quantity between the
MIN mark and the MAX mark on the
dipstick is approximately 2.1 US qts. (2 l).
! 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.
For further information on engine oil, see
(Y page 279).
XReplace cap : on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely.
Checking and adding other service
products
Coolant level
Only check the coolant level when the vehicle
is on a level surface and the engine has cooled
down.
XTurn the key to position 2(Y page 117) in
the ignition lock.
XCheck the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡ (70 †).
GWarning
In order to avoid any potentially serious burns:
Ruse extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system, or
Engine compartment217Maintenance and careZProCarManuals.com

if the coolant temperature display indicates
that the coolant is overheated.
R do not remove the pressure cap on the
coolant reservoir if the coolant temperature
is above 158 ‡ (70 †). Allow the engine to
cool down before removing the cap. The
coolant reservoir contains hot fluid and is
under pressure.
R using a rag, slowly turn the cap
approximately 1
/ 2 turn to relieve excess
pressure. If opened immediately, scalding
hot fluid and steam will be blown out under
pressure.
R do not spill antifreeze on hot engine parts.
Antifreeze contains ethylene glycol which
may burn if it comes into contact with hot
engine parts.
The coolant expansion tank is located in the
engine compartment on the right when
viewed in the direction of travel.XSlowly turn cap : half a turn counter-
clockwise and allow excess pressure to
escape.XTurn cap : further counter-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 ;.
If the coolant is approximately 0.6 in
(1.5 cm) above marker bar = in the filler
neck when warm, there is enough coolant
in coolant expansion tank ;.XIf necessary, add coolant that has been
tested and approved by Mercedes-Benz.XReplace cap : and turn it clockwise as far
as it will go.
For further information on coolant, see
( Y page 280).
Windshield washer system and
headlamp cleaning system
The washer fluid reservoir is used for both the
windshield washer system and the headlamp
cleaning system.
GWarning
Washer solvent/antifreeze is highly
flammable. Do not spill washer solvent/
antifreeze on hot engine parts, because it may
ignite and burn. You could be seriously
burned.
! At temperatures below freezing, always
fill the washer fluid container with a mix of
windshield washer concentrate and
antifreeze additive. There is otherwise a
risk of damaging the windshield washer
system/headlamp cleaning system.
! Only use washer fluid concentrate which
is suitable for plastic lenses. Unsuitable
washer fluid concentrate could damage the
plastic lenses of the headlamps.
! Do not add distilled or de-ionized water to
the washer fluid container. Otherwise, the
level sensor may be damaged.
i Add windshield washer concentrate, e.g.
MB SummerFit, to the washer fluid all year
round.

Raising the vehicleGWarning!
When jacking up the vehicle, only use the jack
which has been specifically approved by
Mercedes-Benz for your vehicle.
The jack is designed exclusively for jacking up
the vehicle under the axle housing. Make sure
the jack is positioned correctly under the axle
housing. The jack must always be vertical
when in use, especially on inclines or
declines.
The jack is intended only for lifting the vehicle
briefly for wheel changes. It is not suited for
performing maintenance work under the
vehicle. To help avoid personal injury, use the
jack only to lift the vehicle during a wheel
change.
Never get beneath the vehicle while it is
supported by the jack. Keep hands and feet
away from the area under the lifted vehicle.
Always lower the vehicle onto sufficient
capacity jackstands before working under the
vehicle.
Always firmly engage the parking brake and
block the wheels with wheel chocks or other
sizeable objects before raising the vehicle
with the jack. Do not disengage the parking
brake while the vehicle is raised.
Make sure that the ground on which the
vehicle is standing and where you place the
jack is solid, level and not slippery. If
necessary, use a large underlay. On slippery
surfaces, such as tiled floors, you should use
a non-slip underlay, for example a rubber mat.
Do not use wooden blocks or similar objects
to support the jack. Otherwise the jack may
not be able to achieve its load-bearing
capacity if it is not at its full height.
Never start the engine when the vehicle is
raised.
Also observe the notes on the jack.
XUsing lug wrench :, loosen the bolts on
the wheel you wish to change by about one
full turn. Do not unscrew the wheel bolts
completely.;Notch on pump leverXAssemble the pump lever for the jack. It can
be found with the vehicle tool kit
( Y page 229).XTurn pressure release screw = clockwise
