To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check engine oil level approximately 5 minutes after
stopping the engine, allowing for the oil to return to the
oil pan.Wipe oil dipstick clean prior to checking the engine oil
level. Fully insert dipstick in tube, and remove after
three seconds to obtain accurate reading.
Oil level must be between the
lower (min) and upper (max) mark of
the dipstick.
Fill quantity between upper and lower dipstick marking
level is approximately 2.1 US qt (2.0 l).
Do not overfill the engine.
Excessive oil must be drained
or siphoned. It could cause damage to engine and
catalytic converter not covered by the Mercedes-Benz
Limited Warranty.
See malfunction and warning messages on page 231 if
an engine oil level display appears on the multifunction
display when the engine is running.
