Maintenance and care Checking the engine oil Check the engine oil every time you fuel your vehicle. Check the engine oil level more frequently if the vehicle is carrying a heavy load, towing a trailer, idling for extended periods (like police, taxi, or shuttle service vehicles), or driven at high speeds for extended periods of time. To check engine oil: 1. Once the engine is warm, turn the engine off. Make sure the vehicle is parked on level ground. 2. Depress the parking brake. Place the gearshift in P (Park). 3. Open the hood. Protect yourself from engine heat. 4. Remove the engine oil dipstick and wipe clean. Reinsert the dipstick fully, then remove it again. The oil level should be between the MIN and MAX lines. If the oil level lies between the MIN and MAX lines, there is no need to add. 5. If the oil level is below the MIN line, add engine oil as necessary and recheck the oil level. If the oil level is above the letter ''M'' in ''MAX,'' engine damage and/or high oil consumption may occur and some oil must be removed from the engine. MIN MAX 141
