Oil Pressure Gage
Standard Cluster
Digital Cluster
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 other problems causing low oil pressure.
On the digital cluster, a box around the oil pressure symbol will begin to
flash when the oil pressure is low.
A
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.
