2001 CHEVROLET ASTRO light

2-60 Operating the Transmitter
Press and hold the appropriate button on the HomeLink
Transmitter. The indicator light comes on while the
signal is being transmitted.
If the hand
-held transmitter appears to program the
HomeLink Transmitter but does not open your garage
door and if the garage door opener was manufactured
after 1996, the garage door opener may have a ªrolling
codeº system. A rolling code system changes the code
of the garage door opener every time you open or close
the garage door.
To determine if you have this system, press the
button on the HomeLink Transmitter that you have
programmed already. If the indicator light flashes
rapidly for one to two seconds then turns solid, the
garage door opener has a rolling code system. In a
rolling code system, the garage door motor head unit
must be trained to the HomeLink Transmitter.
Training a Garage Opener with a
ªRolling Codeº Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to the HomeLink Transmitter, see
ªProgramming the Transmitterº listed previously.
If you have completed this programming already, you now
need to train the garage door opener motor head unit to
recognize the HomeLink Transmitter. Refer to your garage
door opener owner's manual for the proper transmitter
training procedure for your garage door opener brand.
1. Find the training button on the garage door opener
motor head unit. The exact location and color will
vary by garage door opener brand. If you have
difficulty finding the training button, refer to your
garage door opener owner's manual.
Because of the steps involved, it may be helpful to
have another person available to assist you in
programming the transmitter.
2. Press the training button on the garage door opener
motor head unit. An indicator light will begin to flash
when the motor head unit enters the training mode.
Following this step, you have 30 seconds to start Step 3.

2-61
3. Return to the HomeLink Transmitter in your vehicle
and firmly press and release the HomeLink Transmitter
button you have already programmed for two to
three seconds. Press and release the button again
(you may need to do this step up to three times) to
make sure that the HomeLink Transmitter has been
trained to the garage door opener motor head unit.
Check that the training was successful. The motor head
unit indicator light should no longer be flashing.
The garage door opener should now recognize the
HomeLink Transmitter. You may either use the
HomeLink Transmitter or the hand
-held transmitter to
open the garage door.
If after following these instructions, you still have
problems training the garage door opener, call the
manufacturer of the unit at 1
-800-355-3515.
Erasing Channels
To erase all three programmed channels, hold down the
two outside buttons until the indicator light begins to
flash (after 20 seconds). Release both buttons.
Accessories
Accessories for the HomeLink Transmitter are available
from the manufacturer of the unit. If you would like
additional information, please call 1

2-65 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.
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.

2-66 Safety Belt Reminder Light
When the key is turned to RUN or START, a tone will
come on for about eight 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 about 20 seconds, then
it will flash for about
55 seconds.
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 ªAir Bagº in the Index.
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.

2-67
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
serviced right away.
CAUTION:
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.
Charging System Indicator Light
The charging system light
will come on briefly when
you turn the ignition on, but
the engine is not running, as
a check to show you the
light is working.
Then it should go out once the engine is running.
If it stays on, or comes on while you are driving, you
may have a problem with the electrical charging system.
It could indicate that you have a loose accessory drive
belt, or another electrical problem. Have it checked right
away. Driving while this light is on could drain
your battery.
If you must drive a short distance with the light on, be
certain to turn off all your accessories, such as the radio
and heater/air conditioner.

2-68 Voltmeter
When your engine is not
running, but the ignition is
on (in the RUN position),
the gage shows your
battery's state of charge
in DC volts.
When the engine is running, the gage shows the condition
of the charging system. Readings between the low and
high warning zones indicate the normal operating range.
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
When the ignition is on, the brake system warning light
will 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.
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.

2-69
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 ªTowing Your Vehicleº in the Index.
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.
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
ªBrake System Warning Lightº 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.
