Engine Oil Level Check Check the engine oil level and add the proper oil if necessary. See Engine Oil on page 454 for further details. Notice: It is important to check your oil regularly and keep it at the proper level. Failure to keep your engine oil at the proper level can cause damage to your engine not covered by your warranty.

At Each Fuel Fill It is important to perform these underhood checks at each fuel fill.
