ignition CHEVROLET ASTRO 1996 Owner's Manual

Readings in the low warning zone may occur when a
large number of electrical accessories are operating in
the vehicle and the engine
is left at an idle for an
extended period. This condition
is normal since the
charging system is not able to provide full power at
engine idle.
As engine speeds are increased, this
condition should correct itself as higher engine speeds
allow the charging system to create maximum power.
You can only drive for a short time with
the readings in
either warning zone. If you must drive, turn off all
unnecessary accessories.
Readings in either warning zone indicate a possible
problem in the electrical system. Have the vehicle
serviced as soon as possible.
Brake System Warning Light
Your vehicle’s hydraulic brake system is divided into
two parts. If one part isn’t working, the other part can
still work and stop you. For good braking, though, you
need both parts working well.
If
the warning light comes on, there could be a brake
problem. Have your brake system inspected right away.
BRAKE
This light should come on
briefly when you turn the
ignition key to
RUN. If
it doesn’t come on then,
have it fixed
so it will be
ready to warn
you if
there’s a problem.
2-56

If the light comes on while you are driving, pull off the
road and stop carefully. You may notice that the pedal is
harder to push. Or, the pedal may go closer to the floor.
It may take longer to stop. If the light is still
on, have the
vehicle towed for service. (See “Towing Your Vehicle”
in the Index.)
A CAUTION:
..
Your brake system may not be working properly
if the brake system warning light is on. Driving
with the brake system warning light on can lead
to an accident.
If the light is still on after you’ve
pulled
off the road and stopped carefully, have
the vehicle towed
for service.
When the ignition is on, the brake system warning light
will also come on when
you set your parking brake. The
light will stay on if your parking brake doesn’t release
fully. If
it stays on after your parking brake is fully
released,
it means you have a brake problem.
Anti-Lock Brake System Warning Light
ANTI -
LOCK
With the anti-lock brake
system, this light will come
on when you start your
engine and may stay on
for several seconds.
That’s normal.
If the light stays
on, or comes on when you’re driving,
your vehicle needs service. If the regular brake system
warning light isn’t
on, you still have brakes, but you
don’t have anti-lock brakes. If
the regular brake system
warning light is also on, you don’t have anti-lock brakes
and there’s a problem with your regular brakes. See
“Brake System Warning Light” earlier
in this part.
The anti-lock brake system warning light should come
on briefly when you turn the ignition key to RUN. If the
light doesn’t come
on then, have it fixed so it will be
ready
to warn you if there is a problem.

Malfunction Indicator Lamp
(Service Engine Soon Light)
SERVICE
ENGINE
SOON
Your vehicle is equipped
with a computer which
monitors operation of the
fuel, ignition and emission
control systems.
This system
is called OBD I1 (On-Board
Diagnostics-Second Generation) and is intended to
assure that emissions are at acceptable levels for the
life of the vehicle, helping to produce a cleaner
environment. (In Canada,
OBD I1 is replaced by
Enhanced Diagnostics.) The SERVICE ENGINE SOON
light comes on to indicate that there is a problem and
service is required. Malfunctions often will be indicated
by the system before any problem is apparent, which
may prevent more serious damage to your vehicle. This
system is also designed to assist your service technician
in correctly diagnosing any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.
This light should come on, as a check to show you it is
working, when the ignition is
on and the engine is not
running. If the light doesn’t come on, have it repaired.
This light will also come
on during a malfunction in one
of two ways:
Light Flashing -- A misfire condition has been
detected.
A misfire increases vehicle emissions and
may damage the emission control system
on your
vehicle. Dealer or qualified service center diagnosis
and service is required.
0 Light On Steady -- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.

Check Gages Light Fuel Gage
This light will come on
CHECK
GAGES
If the light comes on and stays on while you are driving,
check your various gages to see if they are in the
warning zones. The
fuel gage tells you
how much fuel
you have
remaining when the
ignition is
on.
When the gage fust indicates EMPTY (E), you still have a
little
fuel left, but you should get more fuel as soon as possible.
Here are things some owners ask about. None of these
indicate a problem with your fuel gage:
0 At the gas station, the gas pump shuts off before the

If you have rear heating or rear air conditioning, you
will have adjustable vents in the rear of the vehicle to
help direct the airflow. The rear air conditioning vents
are located
in the headliner at the rear of the vehicle.
The rear heating vents are located next to the second
and third seat on the driver’s side
of the vehicle, near
the floor. You can move the vents to direct the flow of
air, or close
the vents altogether. When you close a vent,
it will increase the flow of air coming
out of any vents
that are open.
Ventilation Tips
Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.
Rear Window Defogger (Option)
If your vehicle has this option, the rear window will
have lines running across
the glass. These lines heat
your window.
For best results, clear the window
of as much snow or
ice as possible before using the rear window defogger.

0 When you enter a vehicle in cold weather, turn the
blower
fan to HIGH for a few moments .before
driving
off. This helps clear the intake ducts of snow
and moisture, and reduces the chance of fogging the
inside
of your windows. Press the button until the light comes on, then release it.
The rear window defogger will
only work when the
ignition switch is in the RUN position.

You can turn the defogger off at any time by pressing
