so, vary the distance between remote control 0083 and the rear-view mirror.
The required distance between remote con-
trol 0083and 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.
Synchronizing the rolling code
Pay attention to the "Important safety notes"
(Y page 226).
If the garage door system uses a rolling code,
you will also have to synchronize the garage
door system with the integrated garage door
opener in the rear-view mirror. To do this you will
need to use the programming button on the door
drive control panel. The programming button
may be located in different places depending on the manufacturer. It is usually located on the
door drive unit on the garage ceiling.
Familiarize yourself with the garage door drive
operating instructions, e.g. under "Program-
ming additional remote controls", before carry-
ing out the following steps.
Your vehicle must be within reach of the garage
door or gate opener drive. Make sure that nei-
ther your vehicle nor any persons/objects are
present within the sweep of the door or gate.
X Turn the SmartKey to position 2in the ignition
lock (Y page 109).
X Get out of the vehicle.
X Press the programming button on the door
drive unit.

the next step. X
Get into the vehicle.
X Press previously programed button 0044,0087
or 0085 on the integrated garage door opener
repeatedly and in quick succession until the
door closes.
The rolling code synchronization is then com- plete.
Notes on programming the remote con-
trol
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
detected 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) as you follow the programming steps.
X Press and hold one of buttons 0044to0085 on the

Problems when programming If you are experiencing problems programming
the integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
R Check the transmitter frequency used by
garage door drive remote control 0083and
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remote control 0083for the garage door drive.
The integrated garage door opener is com-
patible with devices that have units which
operate in the frequency range of 280 to
433 MHz.
R Replace the batteries in garage door remote
control 0083. This increases the likelihood that
garage door remote control 0083will transmit a
strong and precise signal to the integrated
garage door opener.
R When programming, hold remote control 0083
at varying distances and angles from but-
tons 0044to0085 which you are programming. Try
various angles at a distance between 2and
8 inches (5to 20 cm) or at the same angle but at varying distances.
R If another remote control 0083is available for
the same garage door drive, repeat the same
programming steps with this remote control
0083. Before performing these steps, make sure
that new batteries have been installed in
garage door drive remote control 0083.
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 0084on remote control 0083again before
transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
