Programming the HomeLink Transmitter
Do not use the HomeLink Transmitter with any garage
door opener that does not have the ªstop and reverseº
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.
It is recommended that a new battery be installed in
your hand
-held transmitter for quicker and more
accurate transmission of the radio frequency.
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
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 Training a Garage Door Opener with
ªRolling Codesº next 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.

2-76 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 ªLearnº or ªSmartº 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.
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.

2-82 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 in
kilometers (used in Canada).
Your vehicle has a tamper
-resistant odometer. If you see
ERROR, you'll know someone has probably tampered
with it and the numbers may not be accurate.
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.
But if it can't, then it will be 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
Your trip odometer tells how far you have driven since
you last reset it.
Your trip/select reset switch will go back and forth
between the odometer and the trip odometer if the
button is pressed and released within 1.5 seconds.
If the button is pressed and held for longer than
1.5 seconds while in the trip odometer mode, it will
be reset to zero. If the button is pressed and held for
longer than 1.5 seconds while in the odometer mode,
it will have no effect.
Your trip odometer will work no matter what position
your key is in, and even if the key isn't in.

2-94
Here are four situations you may experience with
your fuel gage. None of these indicate a problem with
the fuel gage.

At the gas station, the fuel pump shuts off before the
gage reads full.

It takes a little more or less fuel to fill up than the
fuel gage indicated. For example, the gage may have
indicated the tank was half full, but it actually took a
little more or less than half the tank's capacity to fill
the tank.

The gage goes back to empty when you turn off
the ignition.

The gage pointer moves while cornering, braking
or acceleration.
Message Center
The message center is located below the temperature
gage or the tachometer gage (if equipped) on the
instrument panel cluster. It gives you important safety
and maintenance facts.
Modes
Service Traction System (If Equipped)
United States Canada
If this message appears when you are driving, there is a
problem with your traction control system and your
vehicle is in need of service.
When this message is displayed, the system will not
limit wheel spin. The message will stay on for 60
seconds and then go out. Four chimes will also be heard.
Adjust your driving accordingly.
When the ignition is turned off, this message will be
displayed again for three seconds to remind you that
your traction control system is not working properly. Be
sure to have your vehicle serviced right away.

new variance zone and resume normal operation.
All the display segments will be illuminated briefly to
acknowledge the change in zone number. A chime will
sound to confirm that the new zone number has been set.Automatic Compass Calibration
The compass is self
-calibrating, which eliminates the
need to manually set the compass. When the vehicle is
new, the calibration process may not be complete. In
these cases CAL will be displayed, and all segments of
the compass will be illuminated where the compass
reading is normally displayed.
All Segments Illuminated
To calibrate the compass, in an area free from
large metal objects, make one to two 360
turns.
The calibration symbol will turn off and the compass
reading will be displayed.

Compass/Temperature mode. Press the RESET button
for at least 10 seconds until the calibration symbol
appears and all segments of the compass display are
illuminated. A chime will sound to confirm that the
calibration mode is active. Release the button and
complete two or three 360
turns in an area free from
large metal objects. The calibration symbol will turn off
and the compass reading will be displayed. A chime will
sound to verify that the calibration is complete.
Error Displays

An error of the speed sensor or fuel sender will
cause
-E- to be displayed.

In the absence of vehicle communications, a
dash ª
--º is displayed.
If one of these error messages appear, see your dealer.
Trip Computer
There are five trip computer displays which may be
stepped through by pushing the MODE button.
The information will appear in the following order:

AVG ECON (Average Fuel Economy): This shows
the average fuel economy since the last reset.

INST ECON (Instantaneous Fuel Economy):
This shows fuel economy for the most recent second
of driving.

RANGE (Trip Range): This shows the estimated
distance that can be traveled with the remaining fuel.
The fuel economy used to calculate range is based on
the last few hours of driving. When in a low fuel
condition, LO is displayed.

FUEL USED (Trip Fuel Used): This shows the
accumulated fuel used since the last reset.

AVG SPEED (Average Speed): This shows the
average speed since the last reset.
Resetting the Trip Computer
Press and hold the RESET button for at least three
seconds. The reset is acknowledged with all segments of
the display lit briefly and a chime. A reset can only be
done in AVG ECON, FUEL USED and AVG SPEED
displays. Each setting must be reset individually.

3-4 Air Conditioning
On very hot days, open the windows long enough to
let hot, inside air escape. This reduces the time for the
vehicle to cool down. Then keep your windows closed
for the air conditioner to work its best.
For quick cool down on very hot days select a fan
setting, turn the mode knob on the control panel to vent;
press the A/C and the recirculation buttons and move the
temperature controls all the way into the blue area. If
this setting is used for long periods of time, the air in
your vehicle may become too dry.
For normal cooling on hot days, turn the mode knob
on the control panel to vent; press the A/C and the
outside air buttons and move the temperature control all
the way into the blue area. The system will bring in
outside air and cool and dehumidify it.
On cool, but sunny days, the sun may warm your upper
body, but your lower body may not be warm enough.
To remedy this you can select a fan setting, turn the
mode knob on the control panel to the bi
-level mode,
press the A/C button, and move the temperature control
to a comfortable setting.
Heating
On cold days, select a fan setting, turn the mode knob on
the control panel to floor, press the outside air button on
and move the temperature control all the way in the red
area. The system will bring in outside air, heat it and
send it to the floor ducts.
Ventilation
For mild outside temperatures when little heating or
cooling is needed, select a fan setting and turn the mode
knob on the control panel to vent. Press the outside
air button and move the temperature controls to a
comfortable setting. Your vehicle also has the
flow
-through ventilation system described later
in this section.
Defogging and Defrosting
Your system has two settings for clearing the front and
side windows. To defrost the windows quickly, use
defroster with the temperature controls all the way in the
red area. To warm passengers while keeping the
windows clear, use defogger. For more information,
see ªRecirculationº in the Index.

3-6 Ventilation System
Change the direction
of the airflow by
adjusting the vents.
Your vehicle's flow
-through ventilation system
supplies outside air into the vehicle when it is
moving. Outside air will also enter the vehicle when
the air conditioning compressor is running and the
outside air button is pressed
If the airflow seems very low when the fan is adjusted to
the highest setting, regardless of the mode setting, your
passenger compartment air filter (if equipped) may need
to be replaced. See ªMaintenance Scheduleº and
ªPassenger Compartment Air Filterº in the Index.Ventilation Tips

Keep the hood and front air inlet free of ice, snow or
any other obstruction (such as leaves). The heater
and defroster will work far better, reducing the
chance of fogging the inside of your windows.

When you enter a vehicle in cold weather, adjust the
mode knob to floor and the fan to the highest speed
for a few seconds before driving off. This helps clear
the intake ducts of snow and moisture and reduces
the chance of fogging the inside of your windows.

Keep the air path under the front seats clear of
objects. This helps air to circulate throughout
your vehicle.

Audio Systems
Your audio system has been designed to operate easily
and give years of listening pleasure. You will get the
most enjoyment out of it if you acquaint yourself with it
first. Find out what your audio system can do and how
to operate all of its controls to be sure you're getting the
most out of the advanced engineering that went into it.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, you can play your audio
system even after the ignition is turned off.
See ªRetained Accessory Powerº in the Index.
Setting the Clock
