lites for vehicle location. If either of
these signals are unavailable, the
Tele Aid system may not function and if
this occurs, assistance must be sum-
moned by other means.

216 Controls in detailUseful featuresProgramming or reprogramming the in-
tegrated remote control
Step 1:
Switch on ignition.
Step 2:

If you have previously programmed an
integrated signal transmitter button
and wish to retain its programming,
proceed to step 3. Otherwise, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when the indicator light be-
gins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory. If you later wish to program a
second and/or third hand-held trans-
mitter to the remaining two signal
transmitter buttons, do not repeat this
step and begin directly with step 3.Step 3:

Hold the end of the hand-held remote
control transmitter6 of the device
you wish to train approximately 2 to
5 in (5 to12 cm) away from the surface
of the integrated remote control locat-
ed on the interior rear view mirror,
keeping the indicator lamp1 in view.
Step 4:

Using both hands, simultaneously
press the hand-held transmitter
button5 and the desired integrated
signal transmitter button (2, 3
or4). Do not release the buttons until
completing step 5.
The indicator lamp1 on the integrat-
ed remote control will flash, first slowly
and then rapidly.Step 5:

When the indicator lamp1 flashes
rapidly, release both buttons.
Step 6:

Press and hold the just-trained inte-
grated signal transmitter button and
observe the indicator lamp1.
If the indicator lamp1 stays on con-
stantly, programming is complete and
your device should activate when the
integrated signal transmitter button is
pressed and released.iThe indicator lamp1 flashes the first
time the signal transmitter button is
programmed. If this button has already
been programmed, the indicator lamp
will only start flashing after
20 seconds.

Confirm the garage door operation by
pressing the programmed integrated
signal transmitter button (2, 3
or4).
Step 13:

To program the remaining two buttons,
repeat the steps above starting with
step 3.Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the inte-
grated signal transmitter to pick up the sig-
nal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.
If you live in Canada or if you are having dif-
ficulties programming a gate operator (re-
gardless of where you live) by using the
programming procedures, replace step 4
with the following:Step 4:

Continue to press and hold the inte-
grated signal transmitter button (2,
3 or4) while you press and re-press
(“cycle”) your hand-held remote con-
trol transmitter6 every two seconds
until the frequency signal has been
learned. Upon successful training, the
indicator lamp1 will flash slowly and
then rapidly after several seconds.

Proceed with programming step 5 and
step 6 to complete.
Operation of integrated remote control

Switch on ignition.

Select and press the appropriate inte-
grated signal transmitter button (2,
3 or4) to activate the remote con-
trolled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.

Erasing the integrated remote control
memory
Switch on ignition.

Simultaneously hold down the signal
transmitter buttons2 and 4, for ap-
proximately 20 seconds, until the indi-
cator lamp1 blinks rapidly. Do not
hold for longer than 30 seconds.
The codes of all three channels are
erased.Reprogramming a single integrated
signal transmitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:

Press and hold the desired signal trans-
mitter button (2, 3 or4). Do not re-
lease the button.

The indicator lamp will begin to flash af-
ter 20 seconds. Without releasing the
integrated signal transmitter button,
proceed with programming starting
with step 3.
iIf you sell your vehicle, erase the codes
of all three channels.
