Resynchronization
Resynchronization may be necessary due to the security
method used by this system. The transmitter does not
send the same signal twice to the receiver. The receiver
will not respond to a signal it has been sent previously.
This will prevent anyone from recording and playing
back the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and simultaneously press and hold the LOCK
and UNLOCK buttons on the transmitter for eight
seconds. The door locks should cycle to confirm
synchronization. If the locks do not cycle, see your
dealer for service.Sliding Door
To open the sliding side door, pull the handle toward the
back and slide the door to the rear until it rests in the
open position.
To close the sliding side door, pull the handle toward the
front and slide the door forward.

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 ICE 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 C and you can release the
buttons. Drive the vehicle in a complete 360
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:

2-53
1. Find your location on the zone map. 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 take 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 briefly 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.

2-58 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 2 to 5 inches (5 to 13 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 red light
on the HomeLink Transmitter flash rapidly.
The rapid flashing indicates that the HomeLink
Transmitter has been programmed. Release both
buttons once the light starts to flash rapidly.

2-59
If you have trouble programming the HomeLink
Transmitter, make sure that you have followed the
directions exactly as described and that the battery in the
hand
-held transmitter is not dead. If you still cannot
program it, turn the hand
-held transmitter end over end
and try again. 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
ªTraining a Garage Door Opener with Rolling Codesº
later in this section or contact the manufacturer of the
unit 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 the button
on the hand
-held transmitter about once a second without
ever releasing the button on the HomeLink Transmitter.
Release both buttons when the indicator light on the
HomeLink Transmitter begins to flash rapidly.

2-61
3. Return to the HomeLink Transmitter in your vehicle
and firmly press and release the HomeLink Transmitter
button you have already programmed for two to
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.

When you close a vent, it will increase the flow of air
coming out of any vents that are open.
If you have rear heating or rear air conditioning, you will
have adjustable vents in the rear of the vehicle to help direct
the airflow. The rear air conditioning vents are located in
the headliner at the rear of the vehicle. The rear heating
vents are located next to the second and third seat on the
driver's side of the vehicle, near the floor. You can move
the vents to direct the flow of air, or close the vents
altogether. When you close a vent, it will increase the flow
of air coming out of any vents that are open.
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, turn the fan to
HI for a few moments 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
