Engine Oil Pressure

Gauge

Metric
English
The oil pressure gauge shows
the engine oil pressure
in kPa (kilopascals) or psi (pounds
per square inch) when the engine is
running.
Oil pressure can vary with engine
speed, outside temperature and oil
viscosity, but readings above the
low pressure zone indicate the
normal operating range. When
the oil pressure reaches the
low pressure zone, the OIL
PRESSURE LOW STOP ENGINE
message will appear in the Driver
Information Center. See Engine Oil
Messages on page 10 8 and Engine
Oil on page 10 8 for more
information.
A reading in the low pressure zone
can be caused by a dangerously
low oil level or some other problem
causing low oil pressure. Check
your oil as soon as possible.
{
WARNING
Do not keep driving if the oil
pressure is low. The engine can
become so hot that it catches fire.
Someone could be burned. Check
the oil as soon as possible and
have the vehicle serviced.
Notice: Lack of proper engine oil
maintenance can damage the
engine. The repairs would not be
covered by the vehicle warranty.
Always follow the maintenance
schedule for changing engine oil.
For vehicles with a Hybrid, see the
Hybrid Supplement for more
