2-70 Programming the HomeLink

Transmitter
Do not use the 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!
The engine should be turned off while programming the
HomeLink Transmitter. Follow these steps to program
up to three channels:
1. If you have not previously programmed a universal
channel, proceed to Step 2. Otherwise, hold down
the two outside buttons on the HomeLink
Transmitter until the indicator light begins to flash
rapidly (approximately 20 seconds). Then release the
buttons. This procedure initializes the memory and
erases any previous settings for all three channels.2. Hold the end of the hand
-held transmitter
approximately one to three inches (three to eight cm)
away from the HomeLink Transmitter making sure
that you can still see the display.
3. Decide which one of the three channels you want to
program. Using both hands, press the hand
-held
transmitter button and the desired button on the
HomeLink Transmitter. Continue to hold both
buttons through Step 4.
4. Hold down both buttons until you see the indicator
light on the HomeLink Transmitter flash, first slowly
then rapidly. The rapid flashing, which could take
up to 90 seconds, indicates that the HomeLink
Transmitter has been programmed. Release both
buttons once the light starts to flash rapidly.

2-78 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.Tachometer (If Equipped)
The tachometer displays the
engine speed in thousands
of revolutions per minute
(rpm). (3800 V6 engine
cluster tachometer shown.)
NOTICE:
Do not operate the engine with the tachometer in
the shaded area, or engine damage may occur.

ªICEº is displayed for two minutes.

2-99
Compass Variance
Compass variance is the difference between magnetic
north and geographic north. In some areas of the
country, the difference is great enough to cause the
compass to give false readings. If this occurs, the
compass variance must be set.
Setting the Variance
Turn the ignition on and cycle the DIC to the
Compass/Temperature mode. Press the RESET
button for approximately five seconds. The last entered
variance zone number and ªVARº will be displayed.
Press the MODE button until the proper variance
number on the map is shown. Press the RESET button to
set the 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 ªCALº will be displayed, and all
segments of the compass will be illuminated where
the compass reading is normally displayed.
All Segments Illuminated

2-100
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.
Manual Compass Calibration
If the compass appears erratic and the calibration
symbol does not appear, you must manually put the
compass into the calibration mode.
Turn the ignition on and cycle the DIC to the
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, the word ªLOº 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.

3-6 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, turn the mode
knob on the control panel to UPPER; push the A/C
button on; push the RECIRCULATION button on and
move the temperature control(s) 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 UPPER; push the A/C button on;
push the OUTSIDE AIR button on and move the
temperature control all the way into the blue area. The
system will bring in outside air and cool 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 turn the mode knob on the
control panel to BI
-LEV. Push the A/C button on and
move the temperature control to a comfortable setting.
Heating
On cold days, turn the mode knob on the control panel
to LOWER, push 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, turn the mode knob on the control
panel to UPPER; push the A/C button off; push the
OUTSIDE AIR button on and move the temperature
control(s) 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
DEFROST with the temperature control(s) all the way
in the red area. To warm passengers while keeping the
windows clear, use DEFOG. For more information,
see ªRecirculationº in the Index.

3-8 Ventilation System
Adjust the direction
of airflow by moving
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
fan is running and the OUTSIDE AIR button is pushed.
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 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 LOWER 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.
