See “Checking engine oil level”, on page 300 for
instructions on adding engine oil.
“ENGINE OIL LEVEL – REDUCE OIL LEVEL”
Do not overfill the engine.
Excessive oil must be siphoned or drained off. It could
cause damage to the engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty.
The “PERF. SERV. ON TIME” message will be displayed
if a proper oil level check cannot be performed. The
engine oil level check can be repeated after a short
while.
Perform the engine oil level check with the dipstick, if it
cannot be completed via the multifunction display.
See “Checking engine oil level”, on page 300.
In this case we recommend that you have the system
checked at a Mercedes-Benz Center.
Notes:
See malfunction and warning messages on page 274
and page 283 if an engine oil level indicator appears on
the multifunction display when the engine is running.
The engine oil level cannot be checked while the engine
is running. The “ENGINE OIL LEVEL – NOT WHEN
ENGINE ON” message will appear.
Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.
