Synchronizing the rolling code
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.
Observe the safety notes when performing
the rolling code synchronization.
X Turn the SmartKey to position 2 in the
ignition lock.
X Press the programming 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
initiate the next step.
X Press previously programmed button ;,
= or ? of the integrated garage door
opener until the door closes.
The rolling code synchronization is then
complete.
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 are
designed to "time-out" in the same manner.
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 433MHz.
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 the322
