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.

DO NOT USE SAE 2OW-50 OR ANY OTHER
GRADE OIL NOT RECOMMENDED
As shown in the chart, SAE 5W-30 is best for your vehicle. However, you
can use SAE 1 OW-30 if it's going to be 0°F (-1 SOC) or above. These
numbers on an oil container show
its viscosity, or thickness. Do not use
other viscosity oils, such as SAE 2OW-50.
