tween the lower (min) and upper (max)
mark of the dipstick.

Add engine oil if necessary.iFill quantity between upper and lower
dipstick marking, the level is approxi-
mately 2.1 US qt (2.0 l).

The oil dipstick1 tube allows for drain-
ing of oil by using a suction device.
Warning!
G
In order to avoid any possibly serious burns:

Use extreme caution when opening the
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature display in-
dicates that the coolant is overheated.


Do not remove pressure cap on coolant
reservoir if engine temperature is above
194°F (90°C). Allow engine to cool
down before removing cap. The coolant
reservoir contains hot fluid and is under
pressure.


Using a rag, slowly open the cap approx-
imately
1⁄2turn to relieve excess pres-
sure. If opened immediately, scalding
hot fluid and steam will be blown out un-
der pressure.


Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene gly-
col which may burn if it comes into con-
tact with hot engine parts.

236 OperationVehicle careHard plastic trim items
Pour Mercedes-Benz approved Interior
Care onto soft lint-free cloth and apply
with light pressure.
Headliner
Clean with soft bristle brush, or use a
dry-shampoo cleaner in case of excessive
dirt.
Seat belts
The webbing must not be treated with
chemical cleaning agents. Use only clear,
lukewarm water and soap. Do not dry the
webbing at temperatures above 176°F
(80°C) or in direct sunlight.Upholstery
Using aftermarket seat covers or wearing
clothing that have the tendency to give off
coloring (e.g. when wet etc.) may cause
the upholstery to become permanently dis-
colored. By lining the seats with a proper
intermediate cover, contact-discoloration
will be prevented.
Leather Upholstery
Wipe leather upholstery with a damp cloth
and dry thoroughly or clean with
Mercedes-Benz approved Leather Care.
Exercise particular care when cleaning per-
forated leather as its underside should not
become wet.
Cloth Upholstery
Clean with soft bristle brush, or use a
dry-shampoo cleaner in case of excessive
dirt.MB Tex upholstery
Pour Mercedes-Benz approved Interior
Care onto soft lint-free cloth and apply
with light pressure.
Plastic and rubber parts
Do not use oil or wax on these parts.
Illuminated door sill panels
Use a gentle dishwashing detergent or
mild detergent for delicate fabrics as a
washing solution. Wipe with a cloth moist-
ened in lukewarm solution. Do not use
scouring agents.Warning!
G
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.

255 Practical hints
What to do if …
When the ENGINE OIL LEVEL – CHECK
LEVEL! message appears while the engine
is running and at operating temperature,
the engine oil level has dropped to approx-
imately the minimum mark on the dipstick.
When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.If no oil leaks are noted, continue to drive
to the nearest service station where the
engine oil should be topped to the “full”
mark on the dipstick with an approved oil.:
ENGINE OIL
VISIT WORKSHOP!
The engine oil has dropped to a crit-
ical level.

Check the engine oil level
(page 218) and add oil as re-
quired.

If you must add engine oil fre-
quently, have the engine
checked for possible leaks.
