Transmission fluid level
The transmission fluid level does not need to
be checked. If you notice transmission fluid
loss or gearshifting malfunctions, have an
authorized Mercedes-Benz Center check the
transmission.
Coolant level
The engine coolant is a mixture of water and
anticorrosion/antifreeze.
When checking the coolant level, the vehicle
must be parked on level ground, and the cool-
ant temperature must be below 158‡
(70†).
G Warning!
In order to avoid any potentially serious
burns:
Use extreme caution when opening the
R
hood if there are any signs of steam or
coolant leaking from the cooling system,
or if the coolant temperature indicator
indicates that the coolant is overheated.
Do not remove pressure cap on coolant
R
reservoir if coolant temperature is above
158‡ (70†). Allow engine to cool down
before removing cap. The coolant reser-
voir contains hot fluid and is under pres-
sure.
Using a rag, slowly open the cap approx-

col which may burn if it comes into con-
tact with hot engine parts.
