Programming or reprogramming the integrated
remote control:
1. Turn key in starter switch to position 1 or 2.
2. Hold the end of the hand-held transmitter of the
device you wish to train approximately 2 to 5 inches
(5 cm to 12 cm) away from the surface of the
integrated remote control located on the inside rear
view mirror, keeping the indicator lamp in view.
3. Using both hands, simultaneously push the hand-
held transmitter button and the desired integrated
remote control button. Do not release the buttons
until completing step 4.
4. The indicator lamp on the integrated remote control
will flash, first slowly and then rapidly. When the
indicator lamp flashes rapidly, both buttons may be
released (the rapid flashing lamp indicates
successful programming of the new frequency
signal). To program the remaining two buttons,
follow steps 1 through 4.Note:
If, after repeated attempts, you do not successfully
program the integrated remote control device to learn
the signal of the hand-held transmitter, the garage door
opener could be equipped with the “rolling code
feature”.
Rolling code programming:
To train a garage door opener (or other rolling code
devices) with the rolling code feature, follow these
instructions after completing the “Programming”
portion of this text. (A second person may make the
following training procedures quicker and easier.)
1. Locate training button on the garage door opener
motor head unit. Exact location and color of the
button may vary by garage door opener brand. If
there is difficulty locating the transmitting button,
reference to garage door opener operator’s manual.
2. Press “training” button on the garage door opener
motor head unit (which activates the “training
light”).

Following step 2, there are 30 seconds to initiate
step 3.
3. Firmly press and release the programmed
integrated remote control transmit button. Press
and release same button a second time to complete
the training process. (Some garage door openers
may require you to do this procedure a third time to
complete the training.)
4. Confirm the garage door operation by pressing the
programmed button on the integrated remote
control transmitter.
Canadian programming:
During programming, your hand-held transmitter may
automatically stop transmitting. Continue to press and
hold the integrated remote control transmitter button
(note steps 2 through 4 in the “Programming” portion)
while you press and re-press (“cycle”) your hand-held
transmitter every two seconds until the frequency
signal has been learned. The indicator lamp will flash
slowly and then rapidly after several seconds upon
successful training.Operation of remote control:
1. Turn key in starter switch to position 1 or 2.
2. Select and press the appropriate button to activate
the remote controlled device. The integrated remote
control transmitter continues to send the signal as
long as the button is pressed – up to 20 seconds.
Erasing the remote control memory:
1. Turn key in starter switch to position 1 or 2.
2. Simultaneously holding down the left and right side
buttons for approximately 20 seconds, or until the
control lamp blinks rapidly, will erase the codes of
all three channels.

and hold.
The rear quarter windows cannot be raised with the
hardtop lowered.
Notes:
For safety reasons, the hardtop cannot be lowered while
driving.
Lowering a wet hardtop can result in water reaching the
vehicle interior. The hardtop should be dry when
lowering it into the storage compartment.
Wa r n i n g !
To prevent possible accidents, drive the vehicle
only with the hardtop either completely closed and
locked, or fully lowered into its storage
compartment.
