What to do if …
When the
ENGINE OIL LEVEL – CHECK
LEVEL!
message appears while the engine
is running and at operating temperature,
the engine oil level has dropped to approx-
imately the minimum mark on the dipstick.
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 service station where the
engine oil should be topped to the “full”
mark on the dipstick with an approved oil.
