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 269).
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 121).
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 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 recognized during programming. Comparable
with Canadian law, some U.S. garage door open-
ers also feature a "break". Proceed as follows:

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.
