Engine Oil If the low oil level light appears on the instrument panel, it means you need to check your engine oil level right away. For more information, see "CHECK OIL Light" 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 is located behind the radiator hose on the driver's side of the engine. The yellow looped handle helps to identify it. See "Engine Compartment Overview" in the Index for more information on location. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level. 6-11
