2007 CHEVROLET TRAIL BLAZER check engine

Oil Pressure Gage
The oil pressure gage shows the engine oil
pressure in psi (pounds per square inch) when
the engine is running. Canadian vehicles indicate
pressure in kPa (kilopascals).
{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.
Oil pressure may vary with engine speed, outside
temperature and oil viscosity, but readings above
the low pressure zone indicate the normal operating
range.
A reading in the low pressure zone may be
caused by a dangerously low oil level or other
problems causing low oil pressure.

Service Four-Wheel Drive
Warning Light
This light should come
on briey when you
turn on the ignition,
as a check to show
you it is working.
The service four-wheel drive light comes on,
except for the SS model, to indicate that there
may be a problem with the drive system and
service is required. Malfunctions can be indicated
by the system before any problem is apparent,
which may prevent serious damage to the vehicle.
This system is also designed to assist your GM
dealer in correctly diagnosing a malfunction.
Check Gages Warning Light
The check gages light
will come on briey
when you are starting
the engine.
If the light comes on and stays on while you
are driving, check your coolant temperature and
engine oil pressure gages to see if they are in
the warning zones.

If this light comes on,
the liftgate or liftglass
is not completely shut.

Fuel Gage
When the ignition is on, the fuel gage tells you
about how much fuel you have remaining.
Here are four things that some owners ask about.
None of these show a problem with your fuel gage:
At the gas station, the gas pump shuts off
before the gage reads full.
It takes a little more or less fuel to ll up than
the 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 moves a little when you turn a corner
or speed up.
The gage doesn’t go back to empty when you
turn off the ignition.
Low Fuel Warning Light
The light next to the fuel gage will come on briey
when you are starting the engine.
This light comes on when the fuel tank is low on
fuel. To turn it off, add fuel to the fuel tank.
Check Gas Cap Light
If your vehicle has this
light, it will come on if
your gas cap is not
securely fastened.
