Engine Oil If this symbol, along with the LOW OIL LEVEL message appears on the Driver Information Center (DIC), it means you need to check the engine oil level right away. For more information, see LOW OIL LEVEL under DIC Warnings and Messages on page 3-72. You should check the engine oil level regularly; this is an added reminder. Checking Engine Oil It is a good idea to check the 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 loop. See Engine Compartment Overview on page 5-12 for the location of the engine oil dipstick. 1. Turn off the engine and give the oil several minutes to drain back into the oil pan. If you do not do this, the oil dipstick might not show the actual level. 2. 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. 5-16
