Operation

Engine compartment

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.

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. 

1 Coolant expansion tank
2 Float in the filler neck

왘

Using a rag, turn the cap to the left to 
the first detent position. Allow any ex-
cess pressure to escape.

왘

Continue turning the cap to the left and 
remove it.

The coolant level is correct if float 2 
can be seen at the top through the filler 
neck.

In order to avoid any possibly serious burns:

앫

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 gauge indi-
cates that the coolant is overheated.

앫

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.

앫

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.

앫

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.
