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 0043counter-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 346).
i The difference between the minimum
mark and the maximum mark on the oil
dipstick is approximately 2.1 US qt (2 l).X

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
coolant spraying 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. 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 139).
X Check the coolant temperature display in
the instrument cluster.
The coolant temperature must be below
158 ‡ (70 †).
X Slowly turn cap 0043half a turn counter-
clockwise to allow excess pressure to
escape. Engine compartment

X
Turn cap 0043further 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 0087in the filler
neck when warm, there is enough coolant
in expansion tank 0044.
X If necessary, add coolant that has been
tested and approved by Mercedes-Benz.
X Replace cap 0043and turn it clockwise as far
as it will go.

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: washer fluid reservoir
X
To open: pull cap0043upwards by the tab.
X Add the premixed washer fluid.
X To close: press cap 0043onto the filler neck
until it engages. Further information on windshield washer

Brake fluid level !
If you notice that the brake fluid level in
the brake fluid reservoir has fallen to the
MIN mark or less, check the brake system
immediately for leaks. Also check the
thickness of the brake linings. Visit a
qualified specialist workshop immediately.
Do not add brake fluid. This does not
correct the error. Only check the brake fluid level when the
vehicle is on a level surface.
If the brake fluid level is between MIN
mark
0043and MAX mark 0044on the brake fluid
reservoir, it is correct. Maintenance
