Operation
Engine compartment
Oil level in the automatic
transmission
You do not need to check the oil level in
the automatic transmission. Have any oil
loss from the automatic transmission or
problems with gearshifting checked at
a qualified specialist workshop, e.g. a
Mercedes-Benz Service Centre.
Coolant
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 escaping coolant.
Coolant is a mixture of water and anti-
freeze and corrosion inhibitor. Only check
the coolant level when the vehicle is stand-
ing on a level surface and the engine has
cooled down.

Checking the coolant level
The expansion tank is located in the engine

about 1.5 cm higher when the engine is
hot.
Top up the coolant as necessary.
