2003 CHEVROLET ASTRO tow

If a bulb is burned out, replace it to help avoid an
accident.
If the arrows don’t go on at all when you signal
a turn, check for burned-out bulbs and a blown fuse.
See
Fuses and Circuit Breakers on page 5-93.
If you have a trailer towing option with added wiring
for the trailer lamps, a different turn signal flasher
is used. With this flasher installed, the signal indicator
will flash even
if a turn signal bulb is burned out.
Check the front and rear turn signal lamps regularly
to make sure they are working.
Turn Signal On Chime
If your turn signal is left on for more than 3/4 of a mile
(1.2 km), a chime will sound at each flash of the
turn signal. To turn
off the chime, move the turn signal
lever to the center position.
Headlamp High/Low-Beam Changer
To change the headlamps from low beam to high or
high to low, pull the multifunction lever all the way
toward you. Then release it.
When the high beams are
on, this indicator light located on the instrument
panel cluster also will
be on.
Flash-to-Pass
This feature lets you use your high-beam headlamps to
signal a driver in front of you that you want to pass.
It works even
if your headlamps are in automatic.
To use it, pull the turn signal lever toward you, but not
so far that you hear a click.
If your headlamps are in automatic or on low beam,
your high-beam headlamps will turn on. They’ll stay
on
as long as you hold the lever toward you and the
high-beam indicator located on the cluster comes on.
Release the lever to return to normal operation.

Climate Controls
Climate Control System
With this system you can control the heating, cooling
and ventilation for your vehicle.
Turn the right knob clockwise or counterclockwise to
direct the airflow inside of your vehicle. To change
the current mode, select one of the following:
+2 (Bi-Level): This mode directs approximately half
of the air to the instrument panel outlets and directs
most of the remaining air to the floor outlets. Some air
may be directed toward the windshield.
;$’ (Vent): This mode directs air to the instrument
panel outlets.
(Floor): This mode directs most of the air to the
floor outlets with some air directed to the outboard
outlets (for the side windows) and some air directed to
the windshield.
A/C (Air Conditioning): This setting brings in outside
air, cools and dehumidifies it.
MAX A/C (Maximum Air Conditioning): This setting
cools the air the fastest, by recirculating the inside air.
The right knob can also be used to select the defrost
mode. Information on defogging and defrosting can be
found later in this section.
@ (Fan): Turn the left knob clockwise or
counterclockwise to increase or decrease the fan speed.
Temperature Control: Turn the center knob clockwise
or counterclockwise to increase or decrease the
temperature inside your vehicle.

Defogging and Defrosting
Turn the right knob to select the defog or defrost mode.
+3 (Blend): With this setting, the outside air comes
out
of both the floor and defroster outlets. Adjust the
temperature knob for warmer or cooler air. The air
conditioning compressor may operate in this setting to
dehumidfy the air.
9 (Defrost): This setting operates the defroster.
Most of the air comes out near the windshield, with
some going to the floor outlets and front side windows.
The air conditioning compressor may operate in this
setting to dehumidify the air.
The bi-level setting is useful for cold weather with a
large number of passengers or very humid conditions to
help keep the windshield clear. Use defrost to remove
fog or ice from the windshield quickly in extremely
cold conditions. The temperature knob should be in the
red area and the fan control toward high.
Rear Heating System
Your vehicle may have an optional rear heating system
that allows you to adjust the amount of air flowing
into the rear
of the vehicle, from the front-seating area.
This feature works with the main climate-control
system in your vehicle.
The thumbwheel for this system is located to the right
of the audio system.
Turn the thumbwheel up or down to increase or
decrease the amount of heated air sent to the
rear-seating area.

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.
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 on page 4-29.
I
You- -)rake 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.
Anti-Lock Brake System
Warning light
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 section.
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.

If the Light Is Flashing
The following may prevent more serious damage to
your vehicle:
Reducing vehicle speed.
Avoiding hard accelerations.
Avoiding steep uphill grades.
If you are towing a trailer, reduce the amount of
cargo being hauled as soon as it is possible.
If the light stops flashing and remains on steady,
see
“If the Light Is On Steady” following.
If the light continues to flash, when it is safe to do so,
stop the vehicle. Find a safe place to park your vehicle.
Turn the key off, wait at least
10 seconds and restart
the engine.
If the light remains on steady, see “If the
Light
Is On Steady” following. If the light is still flashing,
follow the previous steps, and drive the vehicle to
your dealer or qualified service center for service.
If the Light Is On Steady
You may be able to correct the emission system
malfunction by considering the following:
Did you recently put fuel into your vehicle?
If so, reinstall the fuel cap, making sure to fully
install the cap. See
Filling Your Tank on page 5-8.
The diagnostic system can determine if the fuel cap has
been left off or improperly installed. A loose or missing
fuel cap will allow fuel to evaporate into the atmosphere.
A few driving trips with the cap properly installed
should turn the light off.
Did you just drive through a deep puddle of water?
If
so, your electrical system may be wet. The condition
will usually be corrected when the electrical system
dries out.
A few driving trips should turn the light off.
Have you recently changed brands of fuel?
If
so, be sure to fuel your vehicle with quality fuel.
See
Gasoline Octane on page 5-5. 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, misfiring,
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.

GAGES
The CHECK GAGES light
will come on briefly when
you are starting the engine.
Fuel Gage
I
UNLEADED
United States Canada
The
fuel gage tells you approximately how much fuel
you have remaining when the ignition is on.
When the gage first indicates empty, you still have a
little fuel left, but you should get more fuel as soon
as possible.
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.
