When the message:
ADD 1.0 QT. OIL
AT FILLING STATION
(Canada: 1.0 LITER )
appears while the engine is running and at
operating temperature, the engine oil level
has dropped to approximately the mini-
mum level.
352
Possible cause/consequence
The engine oil has dropped to a critical
level.
There is water in the engine oil.
The measuring system is malfunctioning.
When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.
Visually check for oil leaks. If no obvious oil
leaks are noted, drive to the nearest ser-
vice station where the engine oil should be
topped to the required level with an ap-
proved oil specified in the Factory
Approved Service Products pamphlet.
Possible solution
Check the engine oil level ( page 275)
and add engine oil as required
( page 278).
If you must add engine oil frequently,
have the engine checked for possible
leaks.
Have the engine oil checked.
Have the measuring system checked by
an authorized Mercedes-Benz Center.
!
The engine oil level warnings should
not be ignored. Extended driving with
the symbol displayed could result in
serious engine damage that is not
covered by the Mercedes-Benz Limited
Warranty.
