CAUTION:
Don’t keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have
your vehicle serviced.
Notice: Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.
Low Oil Level Light
This light should come on
as a check, when you start
your engine. If the light fails
to come on, have it
repaired as soon as
possible so you will be
aware when the oil level
is low.
If this light comes on and stays on, it means your
engine is low on oil. You need to check the oil level
right away. See
Engine Oil (DURAMAX™ Diesel)
on page 5-9 for further information.
