If the garage door system uses a rolling code,
you will also have to synchronise 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 but-
ton may be placed at different locations depend-
ing on the manufacturer. It is usually located on
the door drive unit on the garage ceiling.
Familiarise yourself with the garage door drive
operating instructions, e.g. under "Program-
ming of additional remote controls", before car-
rying out the following steps.
Your vehicle must be within range 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.

Problems when programming
If you have problems when programming the
integrated garage door opener, please note the
following:
Check the transmitter frequency used by
R
garage door drive remote control A and
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remote control A for the garage door drive.
Replace the batteries in garage door remote
R
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.
When programming, hold remote control A
R
at varying distances and angles from but-
tons ; to ? which you are programming. Try
various angles at a distance between 5and
20 cm or at the same angle but at varying
distances.
If another remote control A is available for
R
the same garage door drive, perform the pro-
gramming steps again using this remote con-
trol A. Before performing these steps, make
sure that new batteries have been fitted in
garage door drive remote control A.
Note that some remote controls transmit only
R
for a limited period (the indicator lamp on the
remote control goes out). Press button B on
remote control A again before transmission
ends.
Align the aerial cable of the garage door
R
opener unit. This can improve signal recep-
tion/transmission.
