Oil level in automatic transmission*
There is no need for you to check the oil
level in the automatic transmission. In the
event of oil loss or problems with gear
shifts, have the automatic transmission
checked at a qualified specialist workshop,
e.g. at a Mercedes-Benz Service Centre.
Coolant
Coolant is a mixture of water, antifreeze
and corrosion inhibitor. Only check the
coolant level when the vehicle is standing
on a level surface and the engine has
cooled down.
The expansion tank is located in the engine
compartment on the right-hand side when
viewed in the direction of travel.
G
Risk of injury
The cooling system is pressurised. You
should therefore only unscrew the cap once
the engine has cooled down. You could oth-
erwise be scalded by hot coolant.

1 Expansion tank
Slowly unscrew the cap by about one
half turn and allow excess pressure to
escape.
Then continue to unscrew the cap and
remove it.
The coolant level is correct if:
when the coolant is cold, it reaches
the mark in the expansion tank filler
neck
when the coolant is hot, it reaches
approximately 1.5 cm higher
Engine compartment
Top up the coolant in the filler neck if
necessary.
Replace the cap by turning it to the
stop.
You will find further information about
coolant in the "Technical data" section
( page 415).
