Important safety notes
GWARNING
If children are left unsupervised in the vehicle,
they could:
Ropen the doors, thus endangering other
people or road users.
Rget out and disrupt traffic.
Roperate the vehicle's equipment.
Additionally, children could set the vehicle in

reach of children.
GWARNING
If you attach heavy or large objects to the
SmartKey, the SmartKey could be uninten-
tionally turned in the ignition lock. This could
cause the engine to be switched off. There is a risk of an accident.
Do not attach any heavy or large objects to theSmartKey. Remove any bulky key rings before
inserting the SmartKey into the ignition lock.
!Keep the SmartKey away from strong
magnetic fields. Otherwise, the remote
control function could be affected.
Strong magnetic fields can occur in the
vicinity of powerful electrical installations.
Do not keep the SmartKey:
Rwith electronic devices, e.g. a mobile
phone or another SmartKey.
Rwith metallic objects, e.g. coins or metal
foil.
Rinside metallic objects, e.g. a metal case.

wit h the integrated garage door opener, per-
sons inthe range of movement of the garage
door can become trapped or struck bythe
garage door. There isa risk of injury.
When using the integrated garage door
opener, always make sure that nobody is
wit hin 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 inenclosed spaces with-
out sufficient ventilation.

When indicator lamp :flashes green: pro-
graming was successful. The next step is to
synchronize the rolling code (
Ypage 291).
XRelease button Bon remote control Afor
the garage door drive system.
If indicator lamp :lights up red: repeat the
programing procedure for the correspond-
ing button on the rear-view mirror. When
doing so, vary the distance between remote
control Aand the rear-view mirror.
The required distance between remote
control Aand the integrated garage door
opener depends on the garage door drive
system. Several attempts might be neces-
sary. 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 290).
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 programing button on the
control panel of the door drive. The program- ing button may be positioned in different pla-
ces depending on the manufacturer. It is usu-
ally located on the door drive unit on the
garage ceiling.
Familiarize yourself with the garage door
drive operating instructions, e.g. under "Pro- graming of additional remote controls",
before carrying out the following steps.
Your vehicle must be within reach 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.
XTurn the SmartKey to position
2in the igni-
tion lock (
Ypage 147).
XGet out of the vehicle.
XPress the programing button on the door
drive unit.
Usually , you now have 30 secon
ds to ini-
tiate the next step.
XGet into the vehicle.
XPress previously programed button ;,=
or ? on the integrated garage door opener
repeatedly until the door closes.
The rolling code synchronization is then
complete.
Notes on programing the remote control
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
programing. Comparable with Canadian law,
some U.S. garage door openers also feature a
"break".
Proceed as follows:
Rif you live in Canada
Rif you have difficulties programing the
garage door opener (regardless of where
you live) when using the programing 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.
XPress button Bof garage door remote
control Afor two seconds, then release it
