Checking engine oil level
1Oil filler capTo 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.
The engine oil level can be checked via the
multifunction display in the instrument cluster.
Unscrew the oil filler cap and add oil carefully if you
need to top up the oil. Fill quantity between upper and
lower dipstick marking level is approximately 2.1 US qt
(2.0 l). Re-install oil filler cap.
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 274 if
an engine oil level display appears on the multifunction
indicator when the engine is running.
Note:
See page 128 for engine oil level indicator.
