Regular automatic transmission fluid
level checks are not required. For this
reason the dipstick opening is sealed.
When noticing fluid loss or gear shifting
malfunctions, we recommend 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.
To pull dipstick from tube, break seal by
moving plastic pin (1) sideways. Then
open cap by releasing locking lever (2).
Measure fluid level with the dipstick
completely inserted and the locking lever
released (2).
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 level of the transmission fluid is
dependent upon its temperature. Two
sets of maximum and minimum fluid
level marks on the dipstick are
applicable references only if the
transmission fluid has either reached
its normal operating temperature of
176° F (80°C), or its temperature is
86°F (30°C).
Important!
The fluid level must not exceed the
dipstick maximum mark. Drain or
siphon excess fluid, if required.
Then push dipstick all the way in and
swing locking lever downward (3).
Note:
Damage to transmission caused by
contamination of transmission fluid or
overfilling of transmission may result
in serious transmission damage which
is not covered by the Mercedes-Benz
Limited Warranty.
