CHEVROLET 2009 Silverado - Manual (Page 36)

Oil Pressure Light
{ CAUTION:
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 in this manual for
changing engine oil.
This light comes on briefly
as a check it works, when
the ignition is in ON/RUN.
If it does not, have the
vehicle serviced.
If the light comes on and stays on, it means that oil is
not flowing through the engine properly. The vehicle
could be low on oil and might have some other system
problem.
During an AUTO STOP there is zero oil pressure, but
this light will not come on.
