Synchronising the rolling code
Observe the "Important safety notes"
(Y page 369).
If the garage door system uses arolling code,
you will also have to synchronise the garage
door system with the integrated garage door
opener in the rear-view mirror .Todothis you
will need to use the programming button on
the door drive control panel. The program-
ming button may be placed at differen tloca-
tion sdepending on the manufacturer. It is
usually located on the door drive unit on the
garage ceiling.
Familiarise yourself with the garage door
drive operatin ginstructions, e.g. under "Pro-
grammin gofadditional remot econtrols",
before carrying out the following steps.
Your vehicle must be within range of the
garage door or gate opener drive. Make sure
that neither 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

Problems when programming
If you have problems when programming the

garage door drive remot econtrol Aand
whether it is supported. The transmitter
frequenc ycan usually be found on the back
of the garage door drive remot econtrol.
R Replace the batteries in garage door
remot econtrol A.This increases the like-
lihood that garage door remot econtrol A
will transmit astrong and precise signal to
the integrated garage door opener in the
rear-view mirror.
R When programming, hold remot econtrol
A at varying distances and angles from the
button which you are programming. Try var- ious angles at adistanc ebetween 5and
30 cm or at the same angle but at varying
distances.
R If ther eisanother remot econtrol for the
same garage door drive, perform the pro-
grammin gsteps again using this remote
control. Befor eperforming these steps,
make sure that new batteries have been
fitted in garage door drive remot econtrol
A.
R Note that some remot econtrols transmit
only for alimited period (the indicator lamp
on the remot econtrol goes out). Press but-
ton Bon remot econtrol Aagain before
transmission ends.
R Align the aerial cable of the garage door
