Adding engine oil
HEnvironmental note
When adding oil, take care not to spill any. If
oil enters the soil or waterways, it is harmful
to the environment.
216Engine compartmentMaintenance and care
ProCarManuals.com
! 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

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.

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.
