NOTICE:
When replacing the battery, use care not to touch
any of the circuitry. Static from your body
transferred to these surfaces may damage
the transmitter.
To replace the battery in the remote keyless entry transmitter:
1. Insert a dime in the slot between the covers of the
transmitter housing near the key ring hole. Remove
the bottom by twisting the dime.
2. Remove and replace the battery with a three
-volt
CR2032 or equivalent battery, positive (+) side up.
3. Align the covers and snap them together.
4. Resynchronize the transmitter.
5. Check the operation of the transmitter.
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 prevents anyone from recording and playing back
the signal from the transmitter.
To resynchronize your transmitter, stand close to your
vehicle and press and hold the LOCK and UNLOCK
buttons on the transmitter at the same time for seven
seconds. The door locks should cycle to confirm
synchronization. If the locks do not cycle, see your
dealer for service.

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 C (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:
1. Find your location on the zone map earlier in this
section. Note 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 universal 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 universal 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 universal 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 universal
transmitter. Continue to press both buttons
through Step 4.

4. Hold down both buttons until you see the red light
on the universal transmitter flash rapidly. The rapid
flashing indicates that the universal transmitter has
been programmed. Release both buttons once the
light starts to flash rapidly.
If you have trouble programming the universal
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, rotate the hand
-held transmitter end over end
and try again. The universal 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 universal transmitter.
Note to 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 universal transmitter. Release both buttons
when the indicator light on the universal transmitter
begins to flash rapidly.
Operating the Transmitter
Press and hold the appropriate button on the universal
transmitter. The indicator light comes on while the
signal is being transmitted.
If the hand
-held transmitter appears to program the
universal transmitter but does not open your garage
door, and if the garage door opener was manufactured
after 1996, the garage door opener may have a ªrolling
codeº system. A rolling code system changes the code
of the garage door opener every time you open or close
the garage door.
To determine if you have this system, press the button
on the universal transmitter that you have programmed
already. If the indicator light flashes rapidly for one to
two seconds, then turns solid, the garage door opener
has a rolling code system. In a rolling code system, the
garage door motor head unit must be trained to the
universal transmitter.

2-61 Training a Garage Door Opener with a
ªRolling Codeº Feature (If Equipped)
If you have not previously programmed the hand-held
transmitter to the universal 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 universal 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.
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.
Note: Following this step, you have 30 seconds to
start Step 3.
3. Return to the universal transmitter in your vehicle
and firmly press and release the universal 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 universal 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
universal transmitter. You may either use the universal
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 universal transmitter are available
from the manufacturer of the unit. If you would like
additional information, please call 1
