already been programmed, indicator
lamp : will only light up yellow after ten
seconds have elapsed.
X Release button ;, = or ?. Indicator
lamp : flashes yellow.
X Point garage door remote control A
towards buttons ; to ? on the rear-view
mirror at a distance of 2 to 8 inches (5 to
20 cm).
i The required distance between remote
control A and the integrated garage door
opener depends on the garage door drive
system. Several attempts might be
necessary. You should test every position
for at least 25 seconds before trying
another position. X
Press
and hold button
B on remote
control
A until indicator lamp : lights up green.
If indicator lamp : lights up green or
flashes, then programming has been
successful.
X Release button B on remote

control A for
the garage door drive system.
X If indicator lamp : lights up red: repeat
the programming procedure for the
corresponding button on the rear-view
mirror. When doing so, vary the distance
between remote control A and the rear-
view mirror.
i If the indicator lamp flashes green after
successful programming, the garage door
system is using a rolling code. After
programming, you must synchronize the
garage door opener integrated in the rear-
view mirror
with

the receiver of the garage
door system.
Synchronizing the rolling code
Observe the "Important safety notes"
(Y page 260).
Your vehicle must be within reach of the
garage door or exterior gate drive. Make sure
that neither your vehicle nor any persons/
objects are present within the sweep of the
door or gate.
X Turn the SmartKey to position 2 in the
ignition lock.
X Press the program button of the door or
gate drive (see the door or gate drive
operating instructions, e.g. under
"programming of additional remote
controls").
i Usually, you now have 30seconds to

Notes on programming the remote
control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after
broadcasting
for a few seconds.
Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers also
feature a "break".
Proceed as follows:
R if you live in Canada
R if you have difficulties programming the
garage door opener (regardless of where
you live) when using the programming
steps
X Press and hold one of buttons ; to ? on
the integrated garage door opener.
After a short

time, indicator lamp : lights
up yellow.
X Release the button.
Indicator lamp : flashes yellow.
X Press button B of garage door remote
control A for two

seconds, then release it
for two seconds.
X Press button B again for two seconds.
X Repeat this sequence on button B of
remote control A until indicator lamp :
lights up green.
If indicator lamp : turns red, repeat the
process.
X Continue with the other programming
steps (see above).
Problems when programming
If you are experiencing problems
programming the integrated garage door
opener on the rear-view mirror, take note of
the following instructions:
R Check the
transmitter

frequency of garage
door drive remote control A. This can
usually be found on the back of the remote
control. The integrated garage door opener is
compatible with devices that have units
which operate in the frequency range of
280to 433
MHz.
R Replace the batteries in garage door
remote control A. This increases the
likelihood that garage door remote control
A

will transmit a strong and precise signal
to the integrated garage door opener in the
rear-view mirror.
R When programming, hold remote control
A at varying distances and angles from the
button that you are programming. Try
various angles at a distance between 2and
12 inches (5to 30 cm) or at the same angle
but at varying distances.
R If another remote control for the same
garage door drive is available, repeat the
same programming steps with this remote
control. Before performing these steps,
make sure that new batteries have been
installed in garage door drive remote
control A.
R Note that some remote controls only
transmit for a limited amount of time (the
indicator lamp on the remote control goes
out). Press button B on remote control
A again before transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.
Opening/closing the garage door After it has been programmed, the integrated
garage door opener performs the function of
the garage door system remote control.
Please also read the operating instructions
for the garage door system.
X
Turn the SmartKey to position 2 in the
ignition lock.
X Press button ;, = or ? which you have
programmed to operate the garage door.
