CHEVROLET ASTRO CARGO VAN 2004 2.G Owners Manual

Have you recently changed brands of fuel?
If so, be sure to fuel your vehicle with quality fuel. See
Gasoline Octane on page 5-4. Poor fuel quality will
cause your engine not to run as efficiently as designed.
You may notice this as stalling after start-up, stalling
when you put the vehicle into gear, misring, hesitation
on acceleration, or stumbling on acceleration. (These
conditions may go away once the engine is warmed up.)
This will be detected by the system and cause the
light to turn on.
If you experience one or more of these conditions,
change the fuel brand you use. It will require at least
one full tank of the proper fuel to turn the light off.
If none of the above steps have made the light turn off,
your dealer can check the vehicle. Your dealer has
the proper test equipment and diagnostic tools to x
any mechanical or electrical problems that may
have developed.Emissions Inspection and
Maintenance Programs
Some state/provincial and local governments have or
may begin programs to inspect the emission control
equipment on your vehicle. Failure to pass this inspection
could prevent you from getting a vehicle registration.
Here are some things you need to know to help your
vehicle pass an inspection:
Your vehicle will not pass this inspection if the SERVICE
ENGINE SOON or CHECK ENGINE light is on or not
working properly.
Your vehicle will not pass this inspection if the OBD
(on-board diagnostic) system determines that critical
emission control systems have not been completely
diagnosed by the system. The vehicle would be
considered not ready for inspection. This can happen if
you have recently replaced your battery or if your
battery has run down. The diagnostic system is
designed to evaluate critical emission control systems
during normal driving. This may take several days
of routine driving. If you have done this and your vehicle
still does not pass the inspection for lack of OBD
system readiness, your GM dealer can prepare the
vehicle for inspection.

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). 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.{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.

Security Light
This light will come on
briey when you turn the
ignition key to START.
The light will stay on until the engine starts. If the light
ashes, the Passlock
®System has entered a tamper
mode. If the vehicle fails to start, seePasslock®
on page 2-17.
If the light comes on continuously while driving and
stays on, there may be a problem with the Passlock
®
System. Your vehicle will not be protected by Passlock®,
and you should see your GM dealer.
Service All-Wheel Drive Light
This light should come on
briey when you turn on
the ignition, as a check to
show you it is working.
The SERVICE AWD light comes on 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 service technician
in correctly diagnosing a malfunction.

Tow/Haul Mode Light
This light should come on
when the tow/haul mode
has been selected.
For more information, see “Tow/Haul Mode” inTowing
a Trailer on page 4-35.
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.
Fuel Gage
The fuel gage tells you approximately how much fuel
you have remaining when the ignition is on.
When the gage rst indicates empty, you still have a
little fuel left, but you should get more fuel as soon
as possible.
United StatesCanada
3-34

Here are things some owners ask about. None of these
indicate a problem with your fuel gage:
At the gas station, the gas pump shuts off before
the gage reads full.
The fuel tank will take either a little more or a little
less fuel to ll up than the gage shows.
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 LOW FUEL light
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.
SeeFuel on page 5-4.
Audio System(s)
Notice:Before adding any sound equipment to
your vehicle, like a tape player, CB radio, mobile
telephone, or two-way radio, make sure that it can
be added by checking with your dealer. Also,
check federal rules covering mobile radio and
telephone units. If sound equipment can be added,
it is very important to do it properly. Added
sound equipment may interfere with the operation
of your vehicle’s engine, radio, or other systems,
and even damage them. Your vehicle’s systems may
interfere with the operation of sound equipment
that has been added improperly.
Figure out which audio system is in your vehicle, nd
out what your audio system can do, and how to operate
all of its controls.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. See
“Retained Accessory Power (RAP)” underIgnition
Positions on page 2-18.
