depends on the garage door drive system.
Several attempts may be required. You
should test every position for at least
25 seconds before trying another position.
Synchronising the rolling code
Observe the "Important safety notes"
(Y page 326).
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.
X Turn the key to position 2in the ignition lock
(Y page 148).

drive unit.
Usually, you now have 30 seconds to initiate
the next step. X
Get into the vehicle.
X Press previously programmed button ;,=
or ? of the integrated garage door opener
until the door closes.
The rolling code synchronisation is then com- plete.
Problems when programming
If you have problems when programming the
integrated garage door opener, please note the following:
R Check the transmitter frequency used by
garage door drive remote control Aand
whether it is supported. The transmitter fre-
quency can usually be found on the back of
remote control Afor the garage door drive.
R Replace 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 in the rear-view mirror.
R When 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 5and
20 cm or at the same angle but at varying
distances.
R If another remote control Ais available for
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.
R Note that some remote controls transmit only
for a limited period (the indicator lamp on theremote control goes out). Press button Bon
remote control Aagain before transmission
ends.
R Align the aerial cable of the garage door
opener unit. This can improve signal recep-
tion/transmission.
Opening or closing the garage door Once programmed, the integrated garage door
opener will assume the function of the garage
door system's remote control. Please also read
the operating instructions for the garage door
system. Features
