Adding engine oil
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 replacement specified 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 0043 counter-clockwise and remove
it.
X Add 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.
Further information on engine oil
(Y page 353).
i The difference between the minimum
mark and the maximum mark on the oil
dipstick is approximately 2.1 US qt (2 l).
X Replace cap 0043 on the filler neck and
tighten clockwise.
Ensure that the cap locks into place
securely. Additional service products
Checking the coolant level G
WARNING
In order to avoid potentially serious burns:
R use extreme caution when opening the
hood if there are any signs of vapor or
coolant leaking from the

cooling system, or
if the coolant temperature display indicates
that the coolant is overheated.
R do not remove the pressure cap on the
coolant tank if the coolant temperature is
above 158 ‡ (70 †). Allow the engine to
cool down before removing the cap. The
coolant tank contains hot fluid and is under
pressure.
R using a cloth, slowly turn the cap
approximately 00C5 turn to relieve excess
pressure. If you open the cap immediately,
pressurized scalding hot fluid and vapor will
be blown out.
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. Engine compartment

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
2 (Y page 139) in the ignition lock.
X Check the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡ (70 †).
X Slowly turn cap 0043 half a turn counter-
clockwise to allow excess pressure to
escape.
X Turn cap 0043

further counter-clockwise and
remove it.
If the coolant is at the level of marker bar
0087

in the filler neck when cold, there is
enough coolant in coolant expansion
tank 0044.
If the coolant level is approximately 0.6 in
(1.5 cm) above marker bar 0087 in the filler
neck when warm, there is enough coolant
in coolant expansion tank 0044.
X If necessary, add coolant that has been
tested and approved by Mercedes-Benz.
X Replace cap 0043 and turn
it
clockwise as far
as it will go.
