2007 CHEVROLET SILVERADO light

Oil Pressure Gage
Your vehicle may have an engine oil pressure
gage. It shows the engine oil pressure in psi
(pounds per square inch) when the engine is
running. Canadian vehicles indicate pressure in
kPa (kilopascals).
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but if readings
are outside the normal operating range, the oil
pressure light will come on. SeeOil Pressure Light
on page 266for more information.A reading outside the normal operating range may
be caused by a dangerously low oil level or
some other problem causing low oil pressure.
Check your oil as soon as possible. See
“OIL PRESSURE LOW” underDIC Warnings and
Messages on page 281andEngine Oil (Gasoline
Engine) on page 502.
{CAUTION:
Do not keep driving if the oil pressure is
low. If you do, your engine can become so
hot that it catches re. You or others could
be burned. Check your oil as soon as
possible and have your vehicle serviced.
Notice:Lack of proper engine oil maintenance
may damage the engine. The repairs would
not be covered by your warranty. Always follow
the maintenance schedule in this manual for
changing engine oil.United StatesCanada

Fuel Gage
When the ignition is on, the fuel gage tells you
about how much fuel you have left in your tank.The gage will rst indicate empty before you are
out of fuel, and you should get more fuel as
soon as possible.
When the fuel tank is low the FUEL LEVEL LOW
message will appear. SeeDIC Warnings and
Messages on page 281for more information.
Here are some situations you may experience with
your fuel gage. None of these indicate a problem
with the fuel gage.
At the gas station, the fuel pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the fuel gage indicated. For example, the
gage may have indicated the tank was half full,
but it actually took a little more or less than
half the tank’s capacity to ll the tank.
The gage goes back to empty when you turn
off the ignition.
If you have a diesel engine, see “Fuel Gage” in
the Diesel Engine Supplement.
