ning and at operating temperature, the en-
gine oil level has dropped to approximately

come on intermittently and then stay on if

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.
