Programming the HomeLink Transmitter
Do not use the HomeLink Transmitter with any garage
door opener that does not have the ªstop and reverseº
safety feature. This includes any garage door opener
model manufactured before April 1, 1982.
Be sure that people and objects are clear of the garage
door you are programming.
Your vehicle's engine should be turned off while
programming the transmitter. Follow these steps to
program up to three channels:
1. If you have previously programmed a transmitter
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (after 20 seconds). Then release the buttons.
This procedure initializes the memory and erases any
previous settings for all three channels.
2. Decide which one of the three channels you want to
program. Hold the end of the hand
-held transmitter
about 1 to 3 inches (3 to 8 cm) away from the
surface of the HomeLink Transmitter so that you can
still see the indicator light.
3. Using both hands, press the hand
-held transmitter button
and the desired button on the HomeLink Transmitter.
Continue to press both buttons through Step 4.4. Hold down both buttons until you see the indicator
light on the HomeLink Transmitter flash slowly and
then rapidly. The rapid flashing indicates that the
HomeLink Transmitter has been programmed.
Release both buttons once the indicator light starts to
flash rapidly.
If you have trouble programming the HomeLink
Transmitter, make sure that you have followed the
directions exactly as described. The HomeLink Transmitter
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 ªRolling Code Programmingº later in this section
or contact the HomeLink Transmitter manufacturer
at 1
-800-355-3515.
Be sure to keep the original hand
-held transmitter
in case you need to erase and reprogram the
HomeLink Transmitter.
Canadian Owners: During programming, the
hand
-held transmitter may automatically stop
transmitting after one or two seconds. In this case, you
should press and re
-press the button on the hand-held
transmitter every two seconds without ever releasing the
button on the HomeLink Transmitter. Release both
buttons when the indicator light on the HomeLink
Transmitter begins to flash rapidly.

Speedometer and Tamper
Resistant 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 vehicle has a tamper
-resistant odometer.
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 that will be done.
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.
Dual Trip Odometers
In addition to the standard odometer, the cluster can also
display two separate trip odometers (designated by the
letter ªAº or ªBº in the display window) as well as your
vehicle's Engine Oil Life (designated by the word OIL in
the display window). The display can be toggled between
the odometer, the trip odometers and engine oil life by
quickly pressing and releasing the trip/reset button located
to the right of the temperature gage. The display toggles
once each time the trip/reset button is pressed for less
than 1.5 seconds. The display toggles in the following
sequence: Odometer
- Trip Odometer A - Trip Odometer
B
- Engine Oil Life. If the engine oil life is left on the
display, it will automatically toggle back to the odometer
after approximately 15 seconds. Each of the two trip
odometers can be used to keep track of different trip
distances (for example, the mileage of a long trip and the
mileage driven on the current tank of fuel). The trip
odometers will continue to keep track of miles (kilometers)
driven even if they are not currently displayed. To reset the
odometer to zero (0), push and hold the trip/reset button
for at least 1.5 seconds, but less than three seconds.
Only the trip odometer that is showing in the display
will be reset.

2-98
Retro-Active Reset
Each of the two trip odometers has a feature called
retro
-active reset. This feature can be used to set
either (or both) trip odometer(s) to the number of
miles (kilometers) driven since the ignition was last
turned on. This can be used if you forget to reset your
trip odometer at the beginning of a trip. To use the
retro
-active reset feature, push and hold the trip/reset
button for at least three seconds. The trip odometer will
then display the number of miles (kilometers) driven
since the ignition was last turned on and you began
driving. (If you use the retro
-active reset feature after
you have started the vehicle, but before you begin
moving, the display will show the number of miles
(kilometers) you drove during the last ignition cycle.)
Once you begin driving, the trip odometer will
accumulate mileage. For example, if you have driven
5.0 miles (8.0 km) since you started your vehicle, and
then activate the retro
-active reset feature, the display
will show 5.0 miles (8.0 km). As you drive, the display
will then increase to 5.1 miles (8.2 km), 5.2 miles
(8.4 km), etc. Only the trip odometer that is displayed
will be affected by the retro
-active reset so that both trip
odometers can be used separately.
Warning Lights, Gages, Messages
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.

2-102 Anti-Lock Brake System Warning Light
The anti-lock brake
system warning light
should come on for a
few seconds when you
turn the ignition key
to RUN.
If the anti
-lock brake system warning light stays on longer
than normal after you've started your engine, turn the
ignition off. Or, if the light comes on and stays on when
you're driving, stop as soon as possible and turn the
ignition off. Then start the engine again to reset the
system. If the light still stays on, or comes on again while
you're driving, the anti
-lock brake system needs service
and you don't have anti
-lock brakes. The brake pedal may
be harder to push, or it may go to the floor. It may take
longer to stop. Adjust your driving accordingly.
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.
Traction Control System Warning
Light (Option)
United States Canada
The traction control system warning light may come on
for the following reasons:

If you turn the system off by pressing the TCS
button located in the center console switchbank the
warning light will come on and stay on. To turn the
system back on, press the button again. The warning
light should go off. See ªTraction Control Systemº in
the Index for more information.

2-103

If there's a brake system problem that is specifically
related to traction control, the traction control system
will turn off and the warning light will come on. If
your brakes begin to overheat, the traction control
system will turn off and the warning light will come
on until your brakes cool down.

If the traction control system is affected by an
engine
-related problem, the system will turn off and
the warning light will come on.
If the traction control system warning light comes on
and stays on for an extended period of time when the
system is turned on, your vehicle needs service.
Engine Coolant Temperature Gage
United States Canada
This gage shows the engine coolant temperature.
If the gage pointer moves into the red area, your engine
is too hot!
It means that your engine coolant has overheated. If you
have been operating your vehicle under normal driving
conditions, you should pull of the road, stop your
vehicle and turn off the engine as soon as possible.
See ªEngine Overheatingº in the Index.

2-104 Malfunction Indicator Lamp (Service
Engine Soon Light in the United States or
Check Engine Light in Canada)
United States Canada
Your vehicle is equipped with a computer which
monitors operation of the fuel, ignition and emission
control systems.This system is called OBD II
(On
-Board Diagnostics-Second Generation)
and is intended to assure that emissions are at acceptable
levels for the life of the vehicle, helping to produce a
cleaner environment. The SERVICE ENGINE SOON or
CHECK ENGINE light comes on to indicate that there
is a problem and service is required. Malfunctions often
will be indicated by the system before any problem is
apparent. This may prevent more serious damage to
your vehicle. This system is also designed to assist
your service technician in correctly diagnosing
any malfunction.
NOTICE:
If you keep driving your vehicle with this light
on, after a while, your emission controls may not
work as well, your fuel economy may not be as
good and your engine may not run as smoothly.
This could lead to costly repairs that may not be
covered by your warranty.

2-105
NOTICE:
Modifications made to the engine, transaxle,
exhaust, intake or fuel system of your vehicle or
the replacement of the original tires with other
than those of the same Tire Performance Criteria
(TPC) can affect your vehicle's emission controls
and may cause the SERVICE ENGINE
SOON or CHECK ENGINE light to come on.
Modifications to these systems could lead to
costly repairs not covered by your warranty.
This may also result in a failure to pass a
required Emission Inspection/Maintenance test.
This light should come on, as a check to show you it is
working, when the ignition is on and the engine is not
running. If the light doesn't come on, have it repaired.
This light will also come on during a malfunction in one
of two ways:

Light Flashing
-- A misfire condition has been
detected. A misfire increases vehicle emissions and
may damage the emission control system on your
vehicle. Dealer or qualified service center diagnosis
and service may be required.
Light On Steady
-- An emission control system
malfunction has been detected on your vehicle.
Dealer or qualified service center diagnosis and
service may be required.
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
ªIf the Light Is On Steadyº 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 ªIf the Light
Is On Steadyº following. If the light is still flashing,
follow the previous steps, and drive the vehicle to your
dealer or qualified service center for service.
