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.The engine oil level can be checked by either the oil
dipstick or via the multifunction display in the
instrument cluster.
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.
The oil level must be between the lower
mark (min) and the upper mark (max)
on the oil 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 261 if
an engine oil level display appears on the multifunction
display when the engine is running.
