Oil pressure can vary with engine
speed, outside temperature and
oil viscosity, but if readings are
outside the normal operating range,
the oil pressure light comes on.
See Engine Oil Pressure Light on
page 5‑31 for more information.
A reading outside the normal
operating range can be caused
by a dangerously low oil level or
some other problem causing low
oil pressure. Check the vehicle's
oil as soon as possible. See “OIL
PRESSURE LOW STOP ENGINE”
under Engine Oil Messages on
page 5‑45 and Engine Oil on
page 10‑7.

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.
If the vehicle has a diesel engine,
