operating temperature, the engine oil level has dropped
to approximately 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.
The engine oil level warnings should not be ignored.
