Important safety notes
GWARNING
When you operate or program the garage door
with the integrated garage door opener, per-
sons in the range of movement of the garage
door can become trapped or struck by the
garage door. There is a risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garage
door.
GWARNING
Combustion engines emit poisonous exhaust
gases such as carbon monoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces with-
out sufficient ventilation.

The required distance between remote con-
trol Aand 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"
(Ypage 268).
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.
XTurn the SmartKey to position 2in the ignition
lock (Ypage 124).
XGet out of the vehicle.
XPress the programming button on the door
drive unit.
Usually, you now have 30 seconds to initiate
the next step.
XGet into the vehicle.
XPress previously programed button ;,=
or ? 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,
t

hese 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 open-
ers also feature a "break".
Proceed as follows:
Rif you live in Canada
Rif you have difficulties programming the
garage door opener (regardless of where you live) when using the programming steps
XPress and hold one of buttons ;to? on the
integrated garage door opener.
After a short time, indicator lamp :lights up
yellow.
XRelease the button.
Indicator lamp :flashes yellow.

gramming was successful. The next step is to
synchronize the rolling code.
XRelease button Bof remote control Aof the
garage door drive.
If indicator lamp :lights up red: repeat the
programming process for the corresponding
button on the rear-view mirror. When doing
so, vary the distance between remote control

Problems when programming
If you are experiencing problems programing
the integrated garage door opener on the rear-
view mirror, take note of the following instruc-
tions:
RCheck the transmitter frequency used by
garage door drive remote controlAand
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remote control Afor the garage door drive.
The garage door opener is compatible with
devices which operate in the frequency range
of 280 to 433 MHz.
RReplace the batteries in garage door remote
control A. This increases the likelihood that
garage door remote control Awill transmit a
strong and precise signal to the integrated
garage door opener.
RWhen programming, hold remote control A
at varying distances and angles from but-
tons ;to? 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.
RIf another remote control Ais available for
the same garage door drive, repeat the same
programming steps with this remote control
A. Before performing these steps, make sure
that new batteries have been installed in
garage door drive remote control A.
RNote that some remote controls only transmit
for a limited amount of time (the indicator
lamp on the remote control goes out). Press
buttonBon remote control Aagain before
transmission ends.
RAlign the antenna cable of the garage door
opener unit. This can improve signal recep-
tion/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.
XTurn the SmartKey to position 2in the ignition
lock (Ypage 124).
XPress button ;,=or? which you have
programmed to operate the garage door.
Garage door system with a fixed code: indi-
cator lamp :lights up green. Garage door system with a rolling code: indi-
