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.
