Your vehicle left the factory programmed to have no
doors lock and none of the doors unlock. You can set the
automatic lock feature to lock all the doors when the
vehicle speed is greater than 15 mph (24 km/h) for
two seconds, and then unlock all the doors once the key
is removed from the ignition. The following instructions
detail how to program your door locks differently than
the factory setting. Choose one of the four programming
options listed above before entering the program mode.
To enter the program mode you need to do the following:
1. Begin with the ignition in OFF. Then pull the turn
signal/multifunction lever toward you and hold it
there while you perform the next step.
2. Turn the key to RUN and OFF twice. Then, with the
key in OFF, release the turn signal/multifunction
lever. Once you do this, you will hear the lock switch
lock and unlock and a 30 second program timer
will begin.3. You are now ready to program the automatic
door locks. Select one of the four programming
options listed above, and follow the instructions.
You will have 30 seconds to begin programming.
If you exceed the 30 second limit, the locks will
automatically lock and unlock to indicate that you
have left the program mode. If this occurs, repeat the
procedure beginning with Step 1.
You can exit the program mode any time by turning the
ignition to RUN (the locks will automatically lock and
unlock to indicate that you are leaving the program mode).
If the lock/unlock switches are not pressed while in the
programming mode, the current auto lock/unlock setting
will not be modified.
See your dealer for more information.

Automatic Transfer Case (If Equipped)
If your vehicle is equipped
with the automatic transfer
case, the transfer case
switches are located to the
right of the steering wheel
on the instrument panel.
Use these switches to shift into and out of four
-wheel
drive. You can choose among four driving settings:2HI: This setting is used for driving in most street and
highway situations. Your front axle is not engaged in
two
-wheel drive. This setting also provides the best
fuel economy.
AUTO 4WD: This setting is ideal for use when road
conditions are variable. When driving your vehicle in
AUTO 4WD, the front axle is engaged, but the vehicle's
power is sent only to the rear wheels. When the vehicle
senses a loss of traction, the system will automatically
engage four
-wheel drive. Driving in this mode results in
slightly lower fuel economy than 2HI.

2-55
The DRL system on some vehicles may turn off
temporarily while the turn signals are activated.
To idle an automatic transmission vehicle with the
DRL off, put the transmission in PARK (P). To idle a
manual transmission vehicle with the DRL off, set the
parking brake. The DRL will stay off until you shift out
of PARK (P) or release the parking brake.
The following does not apply to vehicles sold in Canada.
When necessary, you may turn off the automatic
headlamp system and the Daytime Running Lamps
(DRL) feature by following the steps below:
1. Turn the ignition to RUN.
2. Press the DOME OVERRIDE button four times
within six seconds. After the fourth press of the
button, a chime will sound informing you that the
system is off. The system will revert back to the
automatic on mode when the ignition is turned to
OFF and then to RUN again.
3. To return to the automatic mode, push the DOME
OVERRIDE button four times within six seconds
(a chime will sound), or turn the ignition to OFF
and then to RUN again.
As with any vehicle, you should turn on the regular
headlamp system when you need it.Fog Lamps (If Equipped)
Use your fog lamps for better vision in foggy or misty
conditions. Your parking lamps must be on for your
fog lamps to work.
The fog lamp switch is located on the instrument panel
under the lamp switch. Press the switch to turn the
fog lamps on. Press the switch again to turn them off.
A light will glow in the switch when the fog lamps are on.
Fog lamps will go off whenever your high
-beam
headlamps come on. When the high beams go off,
the fog lamps will come on again.

3. After five seconds, VAR CAL will appear on the
display. When it does, release both buttons.
4. Press US/MET until your zone number appears
on the display.
5. Press ON/OFF to enter your zone number.
Your variance is now set.
Driver Information System (If Equipped)
This system displays the outside air temperature,
compass direction and trip information in the
overhead console.
US/MET: The US/MET (United States/metric) button
allows you to switch the display between the English
and metric system.
MODE: The MODE button can be used to toggle
between three modes of operation: OFF, COMP/TEMP
and TRIP.COMP/TEMP: The display provides the outside
temperature and one of eight compass readings to
indicate the direction the vehicle is facing.
Before you turn on the ignition and move the
vehicle, the temperature indicated will be the last
outside temperature recorded with the ignition on.
If the outside temperature is 37
F (3
C) or lower,
the display will toggle between the word ªICEº and
the current temperature every eight seconds. This is a
warning to the driver that road conditions may be icy,
and that appropriate precautions should be taken.
The compass is self
-calibrating, so it does not need
to be manually set. However, if ªCº (Calibration) is
displayed, the compass will need to be calibrated.
You may also place the compass in a noncalibrated
mode by pressing and holding the MODE and US/MET
buttons simultaneously while in the COMP/TEMP
mode. After about 10 seconds, the compass will display
ªCº and you can release the buttons. Drive the vehicle
in a complete 360 degree circle three times at a speed of
less than 5 mph (8 km/h), and the compass will function
normally. Once the calibration is complete, the display
will return to a compass reading.

Variance is the difference between magnetic north and
geographic north. In some areas, the difference between
the two can be great enough to cause false compass
readings. If this happens, follow these instructions to
set the variance for your particular location:
1. Find your location on the zone map earlier in this
section. Record your zone number.
2. Press and hold both the MODE and the US/MET
buttons in the COMP/TEMP mode.
3. After five seconds, the compass will acknowledge
the variation mode by displaying the current zone
number. When it does, release both buttons.
4. Press US/MET until your zone number appears
on the display.
5. Press MODE to enter your zone number.
Your variance is now set and the display will
return to the COMP/TEMP mode.TRIP: Once in the TRIP mode, pressing the
MODE button will step you through the following
TRIP functions:

AVG ECON: The average fuel economy since the
last reset is displayed.

INST ECON: Instantaneous fuel economy for the
last second of driving is displayed.

RANGE: The display indicates the estimated
distance that can be travelled with the remaining fuel
in the tank, based on the fuel economy for the last
few hours of driving.

FUEL USED: The fuel used since the last reset
is displayed.

AVG SPEED: The average speed since the last
reset is displayed.
To reset the trip computer, press the MODE and
US/MET buttons simultaneously for at least two seconds.
All functions will be displayed for half a second once the
system is reset. Reset can only be performed in the
AVG ECON, FUEL USED and AVG SPEED modes.
All three modes are reset simultaneously.

Programming the 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.
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.

Training a Garage Door Opener with a
ªRolling Codeº Feature (If Equipped)
If you have not previously programmed the
hand
-held transmitter to the HomeLink Transmitter,
see ªProgramming the Transmitterº listed previously.
If you have completed this programming already, you
now need to train the garage door opener motor head
unit to recognize the HomeLink Transmitter. Refer to
your garage door opener owner's manual for the proper
transmitter training procedure for your garage door
opener brand.
1. Find the training 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 training button, refer to your
garage door opener owner's manual.
Because of the steps involved, it may be helpful to
have another person available to assist you in
programming the transmitter.
2. Press the training 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 the HomeLink Transmitter in your
vehicle and firmly press and release the HomeLink
Transmitter button you have already programmed for
two or three seconds. Press and release the button
again (you may need to do this step up to three times)
to make sure that the HomeLink Transmitter has been
trained to the garage door opener motor head unit.
Check that the training was successful. The motor
head unit indicator light should no longer be flashing.
The garage door opener should now recognize the
HomeLink Transmitter. You may either use the
HomeLink Transmitter or the hand
-held transmitter
to open the garage door.
If after following these instructions, you still have
problems training the garage door opener, call the
manufacturer of the unit at 1
-800-355-3515.
Erasing Channels
To erase all three programmed channels, hold down the
two outside buttons until the indicator light begins to
flash (after 20 seconds). Release both buttons.
Accessories
Accessories for the HomeLink Transmitter are available
from the manufacturer of the unit. If you would like
additional information, please call 1
-800-355-3515.

With the automatic setting, the air conditioning
compressor automatically cycles when needed to cool the
air. In cold weather, when the system senses the need for
heat, the airflow will be directed out of the floor outlets.
As the interior temperature approaches a desired setting,
the fan speed will decrease. To maintain interior comfort,
the airflow will adjust between the instrument panel air
outlets and floor outlets. On bright sunny days in cool
weather, the airflow may come out of the air conditioning
and floor outlets (bi
-level mode) to maintain comfort and
prevent stuffiness.
To avoid blowing cold air in cold weather, the system
will delay turning on the fan until warm air is available.
The length of delay depends on the outside air temperature,
engine coolant temperature or the time since the engine was
last started. As the coolant warms up, the fan speed will
gradually increase and air will flow from the heater outlets,
with some airflow to the windshield to prevent fogging
under most normal conditions.
If your vehicle is sitting out on a warm day and you
have the fan set on AUTO, the air will first flow out of
the floor air outlets for a few seconds. That is normal.
This is to expel hot air from the air outlets. As the air is cooled, the airflow will move through the
air conditioning outlets.
Be careful not to put anything over the solar sensor
located around the center of the instrument panel.
This sensor is used by the automatic system to
regulate temperature.
Mode Knob
- Manual Operation
The right knob on the control panel allows you to
choose the direction of air delivery.
You can choose to set the climate control system
operations yourself, or let the system work for you
by placing the system in AUTO mode. See ªMode
Knob
- Automatic Operationº earlier in this section.
VENT: This setting directs most of the air through
the instrument panel outlets and a small amount through
the floor outlets.
BI-LEVEL: This setting directs air through
the heater floor outlets as well as the instrument
panel outlets.
