LEVEL!” message appears while the engine
is running and at operating temperature,
the engine oil level is low.
When this occurs, the warning will first
come on intermittently and then stay on if
the oil level drops further.If no oil leaks are noted, continue to drive
to the nearest gas station where the en-
gine oil should be filled up with an ap-
proved oil (
page 227).
!The engine oil level warnings should
not be ignored. Extended driving with
the symbol displayed could result in se-
rious engine damage that is not cov-
ered by the Mercedes-Benz Limited
