CHECK ENG OIL LEVEL Message
Once oil is added, it may need time to drain and settle in
the engine before this message will turn off. It is best to
let the engine cool down (if it is hot) or warm up (if it is
cold) and cycle the ignition to be sure this message turns
off. Refer to the dipstick for the correct level.
See "Engine Oil" in the Index on how to check the oil
level and for what type of oil to add.
This message is displayed
when the engine oil level
is low.
