Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels.
1. Decide which one of the three channels (one of the
three HomeLink buttons) you want to program.
2. Press and hold the desired button on HomeLink
through Step 3.
3. When the HomeLink indicator light begins to blink
slowly (this may take up to 30 seconds), hold the
hand
-held transmitter about 1 to 3 inches (3 to 8 cm)
away from HomeLink and then press and hold the
transmit button on the hand
-held transmitter.
Continue to hold both buttons until the indicator
light on HomeLink begins to flash rapidly. (This may
take up to 90 seconds).If you have trouble programming HomeLink, make sure
that you have followed the directions exactly as
described and that the battery in the hand
-held
transmitter is not weak. If you still cannot program it,
move the hand
-held transmitter to the left or right or
forward or backward or flip it upside down. HomeLink
may not work with older garage door openers that do
not meet current Federal Consumer Safety Standards.
If you cannot program the transmitter after repeated
attempts, refer to ªTraining a Garage Door Opener with
Rolling Codesº later in this section or contact the
manufacturer of HomeLink at 1
-800-355-3515, or on
the internet at www.homelink.com.
Be sure to keep the original hand
-held transmitter in
case you need to erase and reprogram HomeLink.

2-62 Training a Garage Opener with a
ªRolling Codeº Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter of HomeLink, see ªProgramming the
HomeLink Transmitterº listed previously. If you have
completed this programming already, you now need to
train the garage door opener motor head unit to
recognize HomeLink.
1. Find the ªLearnº or ªSmartº button, refer to
your garage door opener owner's manual or contact
the manufacturer of HomeLink at 1
-800-355-3515
or on the internet at www.homelink.com.
Because of the steps involved, it may be helpful
to have another person assist in programming
the transmitter.2. Press the ªLearnº or ªSmartº 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.
3. Return to HomeLink in your vehicle and firmly
press and release the programmed HomeLink
button three times.
The rolling-code garage door opener should now
recognize HomeLink. You may either use HomeLink or
the hand
-held transmitter to open the garage door.
If after following these instruction, you still have
problems training the garage door opener, contact the
manufacturer of HomeLink at 1
-800-355-3515, or on
the internet at www.homelink.com.

Page 132 of 363
2-68 Tachometer
The tachometer displays the engine speed in thousands
of revolutions per minute (rpm).
NOTICE:
Do not operate the engine with the tachometer in
the shaded area, or engine damage may occur.
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.
Page 133 of 363
2-69
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.
Safety Belt Reminder Light
When the key is turned to ON, a chime 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 chime
nor the light will come on.

2-70 Air Bag Readiness Light
There is an air bag readiness light on the instrument
panel, which shows 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 modules, the
wiring and the crash sensing and diagnostic module.
For more information on the air bag system, see
ªAir Bagº in the Index.
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.
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 ON. If the
light doesn't come on then, have it fixed so it will be
ready to warn you if there is a problem.
