CHEVROLET 2009 Silverado - Manual (Page 35)

A reading in the low pressure zone may be caused by a
dangerously low oil level or some other problem causing
low oil pressure. Check the oil as soon as possible.
{ 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.
AUTO STOP
When the engine goes into Automatic Engine Stop, the
oil pressure gage drops to zero when the tachometer is at
the AUTO STOP position. This is normal and oil pressure
returns to the normal operating range once the engine
starts.
See Starting the Vehicle on page 2-12 for more
information.
AUTO STOP displays in the Driver Information
Center (DIC) when the vehicle speed is zero.
See DIC Warnings and Messages on page 3-12
for more information.
