Remove the hood prop from its slot in the hood and return the prop to its retainer. Then pull the hood down firmly to close. It will latch when dropped from 6 to 8 inches (15 to 20 cm) without pressing on the hood. Engine Oil If the CHECK OIL LEVEL message appears on the instrument cluster, it means you need to check your engine oil level right away. For more information, see "Check Oil Level Message" in the Index. You should check your engine oil level regularly; this is an added reminder. Checking Engine Oil It's a good idea to check your engine oil every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. The engine oil dipstick handle is a yellow ring located in the engine compartment toward the passenger's side of the vehicle. See "Engine Compartment Overview" in the Index for more information on location. 6-11
