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.
Training a Garage Door Opener with a
ªRolling Codeº Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to 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 Learn or Smart 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 Learn or Smart 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 Learn or Smart 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.

2-97
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 instructions, 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.

you press and re
-press (cycle) your hand-held transmitter
every two seconds until HomeLink is trained.

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).
Trip Odometer
The trip odometer can tell you how far your vehicle has
been driven since you last set the trip odometer to zero.
Press the reset button to toggle between the trip
odometer and the regular odometer. Holding the reset
button for two seconds while the trip odometer is
displayed will reset it.
To display the odometer reading with the ignition off,
press the reset button.
Engine Hour Meter Display
The odometer can also display the number of hours
the engine has run. To display the hour meter, turn the
ignition off, press and hold the reset button for at least
four seconds. The hour meter will be displayed for
up to 30 seconds, or until the ignition is turned on.
Tachometer
Your tachometer displays the engine speed in
revolutions per minute (rpm).
Warning Lights, Gages and Indicators
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.

2-102
Your vehicle also has a message center that works along
with warning lights and gages. See ªMessage Centerº in
the Index.
Safety Belt Reminder Light
When the key is turned to RUN or START, a chime
will come on for about six 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.
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 sensors, the air bag
modules, the wiring, the passenger air bag suppression
circuit 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.

2-103
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.
Voltmeter
United States Canada
When your engine is not running, but the ignition is in
RUN, this 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.

2-104
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 reading
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
With the ignition on, the brake system warning light will
flash when you set the parking brake. The light will flash
if the parking brake doesn't release fully. If you try to
drive with the parking brake engaged, a chime will sound
when the vehicle speed is greater than 3 mph (5 km/h).
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.
