Transmission fluid level
The transmission fluid level does not need
to be checked. If you notice transmission
fluid loss or gear shifting malfunctions,
have an authorized Mercedes-Benz Center
check the transmission.
Coolant level
The engine coolant is a mixture of water
and anticorrosion/antifreeze. To check
the coolant level, the vehicle must be
parked on level ground and the engine
must be cool.
The coolant expansion tank is located on
the passenger side of the engine compart-
ment.
For more information on coolant, see
“Coolants” (
୴ page 336).

̈ Using a rag, turn the cap slowly approx-
imately one half turn to the left to re-
lease any excess pressure.
̈ Continue turning the cap to the left and
remove it.
The coolant level is correct if the level
ț for cold coolant: reaches the black
top part of the reservoir
ț for warm coolant: is approx. 0.6 in
(1.5 cm) higher
̈ Add coolant as required.
̈ Replace and tighten cap.
Warning! G
In order to avoid any possibly serious burns:
ț 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.
ț 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.
ț Using a rag, slowly open the cap approx-
imately ½ turn to relieve excess pres-
sure. If opened immediately, scalding
hot fluid and steam will be blown out un-
der pressure.
ț Do not spill antifreeze on hot engine
parts. Antifreeze contains ethylene gly-
col which may ignite and burn if it comes
into contact with hot engine parts.
