Check Engine Oil Pressure Message
When you see this
flashing symbol, the
engine oil pressure
is low.
To acknowledge this warning, press either button on
the outboard switch on the left spoke of the steering
wheel. After you press this button, the warning will
redisplay every 10 minutes until the pressure returns to
the normal operating range. Oil pressure should be
20 to 80 psi (140 to 550 kPa). In certain situations such
as long, extended idles on hot days, it could read as
low as 6 psi (40 kPa) and still be considered normal.
It may vary with engine speed, outside temperature and
oil viscosity. This warning should correspond with the
Oil Pressure Light. See
Oil Pressure Light on page 3-48
for more information.
Oil Temperature Warning Message
When you see this
flashing symbol, the
engine oil temperature
is high.
To acknowledge this warning press either button on
the outboard switch on the left spoke of the steering
wheel. After you press a button, the warning will
redisplay every 10 minutes until the temperature returns
to the normal operating range. Driving aggressively
or driving on long hills can cause the engine oil
temperature to be higher than normal. If this warning is
displayed during normal vehicle operation on flat
roads, your vehicle may need service. See your GM
dealer for an inspection. See
Engine Oil on page 5-16
for more information.
