Oil Pressure Gage - GMC 2003 Sierra 1500 Pickup Owner's Manual

Oil Pressure Gage
United States Canada
The oil pressure gage shows the engine oil pressure in
psi (pounds per square inch) when the engine is
running. Canadian vehicles indicate pressure in
kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and
oil
viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused
by a
dangerously low oil level or some other problem causing
low oil pressure. Check your oil as soon as possible. See
Oil Pressure Low under DIC Warnings and Messages
on
page 3-60 -7d Engine Oil
on
page 5- 17.
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.
