2003 CHEVROLET ASTRO Owners Manual

Rear Air Conditioning System
Your vehicle may have an optional rear air-conditioning
system that allows you to adjust the fan speed in the
rear-seating area, 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 rear-heating system.
Turn the thumbwheel up or down to increase or
decrease the amount of cooled air sent to the
rear-seating area.
Directing the Airflow
To direct the airflow to the rear-seating area, use the
right knob located
on the main climate-control panel.
Generally the upper outlets are used for air conditioning
and the floor outlets are used for heating.
Selecting the Fan Speed
Rear Heat and Rear A/C
8f? (Fan): Move either thumbwheel on either climate
control panel up or down
to HIGH, MED (Medium)
or
LOW to increase or decrease the fan speed in the
rear-seating area. Move the thumbwheel to
OFF to turn
off the fan.
Setting the Temperature
To increase or decrease the temperature for the entire
vehicle use the center knob located on the main
climate-control panel.
The air-conditioning system on the main climate-control
panel must be turned on to direct cooled air to the
rear of the vehicle. If it is not on, then the temperature
in the rear of the vehicle will remain at cabin
temperature.

Be sure to keep the area under the front seats clear of
any objects
so that the air inside of your vehicle can
circulate effectively.
For information on how to use the main climate-control
system. For information
on ventilation, see “Outlet
Adjustment” listed later in this section.
Rear Climate Control System
Rear Window Defogger
Your vehicle may have a rear window defogger that
uses a warming grid
to remove fog or frost from the
rear window.
The rear window defogger will only work when the
ignition is in
RUN.
Press this button to turn
the rear window defogger
on or off. Be sure to
clear as much snow from
the window as possible.
The rear window defogger will turn
off several minutes
after the button is pressed. If turned on again, the
defogger will run for several more minutes before turning
off. The defogger can also be turned off by pressing
the button again or by turning off the engine.
Notice: Don’t use a razor blade or something else
sharp on the inside of the rear window. If you do,
you could cut or damage the defogger and the repairs would not be covered by your warranty.
Do not attach a temporary vehicle license, tape,
a decal or anything similar to the defogger grid.

Outlet Adjustment Operation Tips
1. Clear away any ice, snow or leaves from the
air inlets at the base of the windshield that
may block the flow of air into your vehicle.
2. Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
3. Keep the path under the front seats clear of
objects to help circulate the air inside of your
vehicle more effectively.
Move the thumbwheel in the center of the outlets up or
down to change the direction
of airflow.

Warning Lights, Gages and
Indicators
This part describes the warning lights and gages that
may be on your vehicle. The pictures will help you
locate them.
Warning lights and gages can signal that something is
wrong before it becomes serious enough to cause
an expensive repair or replacement. Paying attention to
your warning lights and gages could also save you
or others from injury.
Warning lights come on when there may be or
is a
problem with one of your vehicle’s functions.
As you
will see in the details on the next few pages, some
warning lights come on briefly when you start the engine
just to let you know they’re working.
If you are familiar
with this section, you should not be alarmed when
this happens. Gages
can indicate when there may be or is a problem
with one of your vehicle’s functions. Often gages
and warning lights work together to let you know when
there’s a problem with your vehicle.
When one
of the warning lights comes on and stays on
when you are driving, or when one of the gages shows
there may be a problem, check the section that tells you
what to do about it. Please follow this manual’s advice.
Waiting to do repairs can be costly
- and even
dangerous.
So please get to know your warning lights
and gages. They’re a big help.

Instrument Panel Cluster
Your instrument panel cluster is designed to let you know at a glance how your vehicle is running. You’ll know how
fast you’re going, about how much fuel you’ve used, and many other things you’ll need
to know to drive safely
and economically.

Speedometer and Odometer
Your speedometer lets you see your speed in both
miles per hour (mph) and kilometers per hour (km/h).
Your odometer shows how far your vehicle has
been driven,
in either miles (used in the United States)
or kilometers (used in Canada).
Your odometer is tamper resistant. The digital odometer
will read
999,999 if someone tries to turn it back.
You may wonder what happens
if your vehicle needs a
new odometer installed.
If the new one can be set to
the mileage total of the old odometer, then it must
be. But
if it can’t, then it’s set at zero, and a label must
be put on the driver’s door to show the old mileage
reading when the new odometer was installed.
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
The trip odometer
will appear in place of your regular
odometer when you press the TRIP button.
To reset the trip odometer, press and hold the TRIP
button. To change back to the regular odometer,
press the TRIP button again.

Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will
come on for several seconds to remind people to fasten
their safety belts, unless the driver’s safety belt is
already buckled.
The safety belt light will
also come on and stay on
for several seconds,
then it will flash for
several more.
If the driver’s belt is already buckled, neither the tone
nor the light will come
on.
Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows AIR BAG or the air bag symbol.
The system checks the air bag’s electrical system
for malfunctions. The light tells you
if there is an
electrical problem. The system check includes the
air bag sensor, the air bag modules, the wiring and
the crash sensing and diagnostic module. For more
information on the air bag system, see
Air Bag System
on page 1-62.
AIR
BAG
United States Canada
This light will
come on when you start your vehicle, and
it will flash for a few seconds. Then the light should
go out. This means the system is ready.
3-26

If the air bag readiness light stays on after you start the
vehicle or comes on when
you are driving, your air
bag system may not work properly. Have your vehicle
s iced right away.
Charging System
If the air bag readiness light stays on after you
start your vehicle,
it means the air bag system
may not be working properly. The air bags in
your vehicle may not inflate
in a crash, or they
could even inflate without a crash. To help avoid
injury to yourself or others, have your vehicle
serviced right away if the air bag readiness light
stays on after you start your vehicle.
The air bag readiness light should flash for a few
seconds 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.
Light
This light should come on
briefly when you turn on
the ignition, before starting the engine, as a check
to show you it is working.
After the engine starts, the light should go out.
if it stays
on or comes on while you are driving, you may have
a problem with your charging system. It could indicate a
problem with the generator drive belt, or some other
charging system problem. Have it checked right away.
Driving while this light is on could drain your battery.
If you must drive a short distance with this light
on,
it helps to turn off all your accessories, such as
the radio and air conditioner.
