Checking and Adding Engine Oil Since the proper amount of engine oil is important for safe engine operation, check the oil using the dipstick each time you put fuel in your vehicle. Remember the engine must be off, the oil must be warm and the vehicle must be parked on level ground. Checking the engine oil level: 1. Turn the engine off after it has warmed up and allow a few minutes for the engine oil to drain back into the oil pan. Set the parking brake, making sure the gearshift is securely latched in P (Park). Open the hood. Protect yourself from engine heat. Locate the engine oil dipstick (highlighted in yellow) and carefully pull it out of the engine. Wipe the dipstick clean and put it back into position, making sure it is fully seated. 2. 3. 4. 5. Engine oil dipstick 6. Carefully pull the dipstick out again. If the oil level is below the "ADD 1 QT" line, add engine oil as necessary. If the oil level is beyond the letter "F" in Full, engine damage or high oil consumption may occur and some oil must be removed from the engine. 212
