Checking Automatic
Transmission Fluid Level
1
Release
2 Engage
When noticing fluid loss or gear
shifting malfunctions, we recom­
mend to have your authorized
Mercedes-Benz dealer check the
transmission fluid level.
The transmission fluid level should
only be checked with the engine
idling, parking brake engaged and
selector lever in position ” P” . The
vehicle must be parked on level
ground.
Prior to the check, allow engine to
idle for approx. 1 to 2 minutes.
Measure fluid level with the
dipstick completely inserted and
the locking lever released (1).
Extreme cleanliness must be
observed! To wipe the dipstick,
use a clean, lint-free cloth.
To fill the transmission with fluid,
pour it through a fine-mesh filter
into the dipstick opening. Even the
slightest impurity may cause
operational troubles.
The fluid level in the transmission
is dependent upon its tempera­
ture. The maximum and minimum
fluid level marks on the dipstick
are applicable references only if
the transmission fluid level has
reached its normal operating
temperature of 176°F (8 0 °C).
Important!
If the transmission fluid cools
down to 68 - 8 6 ° F (20 - 3 0 °C),
which is the normal shop tempera­
ture range, then the maximum
fluid level will be approximately
0.4 in (10 mm) below the mini­
mum mark on the dipstick. We
stress this point because a fluid
change is normally performed
when the transmission fluid has
cooled down to shop temperature.
The fluid level must not exceed
the dipstick maximum mark with
the fluid at operating temperature.
Drain or siphon excess fluid, if
required.
Then push dipstick all the way
in and swing locking lever
downwards (2).
