The engine oil level can only be checked via the
multifunction display in the instrument cluster.
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.Unscrew the oil filler cap and add oil carefully if you
need to top up the oil. Follow the message appearing on
the engine oil level indicator display (page 135) as to
quantity to be added. 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 285 if
an engine oil level display appears on the multifunction
indicator when the engine is running.
Notes:
See page 135 for engine oil level indicator display.
The dipstick tube allows for draining of oil by using a
suction device.
