Underhood Lamp Your underhood lanlp is designed to come on whenever you raise the hood, and either the parking lamps or headlamps are on. Engine Oil It's a good idea to check your engine oil every time you get fuel. In order to getan accurate reading, the oil must be warm and the vehicle must be on level ground. Turn off the engine and give the oil a few minutes to drain back into the oil pan. If you don't, the oil dipstick might not show the actual level. To Check Engine Oil Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down, and check the level. Before closing the hood, be sure all the filler caps areon properly. Then just pull the hood down and close it firmly. 6-7
