Oil Pressure Gage - GMC Sierra Classic 2007 Owner's Manual

Oil Pressure Gage

United States
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 267 and Engine Oil (Gasoline Engine)
on page 482.
Canada
Notice: Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.
CAUTION:
{
Do not 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.
