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.
The engine oil pressure gauge
reads in kPa (kilopascals) or psi
(pounds per square inch) when the
engine is running. Oil pressure may
vary with engine speed, outside
temperature and oil viscosity.
If readings are outside the normal
operating range, the low oil
pressure message may display on
the Driver Information Center (DIC),
or for vehicles without DIC the oil
pressure light comes on. If the oil
level is outside the normal operating
range of 0-548 kPa (0-80 psi), check
the oil level immediately. DO NOT
operate the engine with the oil
pressure warning light on or a
ENGINE OIL LOW ADD OIL
message displayed.
Malfunction
Indicator Lamp
A computer system called OBD II
(On-Board Diagnostics-Second
Generation) monitors operation of
the fuel, ignition, and emission
control systems. It makes sure that
emissions are at acceptable levels
for the life of the vehicle, helping to
produce a cleaner environment.
This light comes on when the
ignition is on, but the engine is not
running, as a check to show it is
working. If it does not, have the
vehicle serviced by your dealer.
