While the memory function is making adjust-
ments, make sure that no one has any body
parts in the sweep of the seat or steering
wheel. If somebody becomes trapped, imme-diately release the memory function position
button. The adjustment process is stopped.
GWARNING
Children could become trapped if they acti-
vate the memory function, particularly when
unattended. There is a risk of injury.
When leaving the vehicle, always take the
SmartKey with you and lock the vehicle. Never
leave children unsupervised in the vehicle.
With the memory function, you can store up to
three different settings, e.g. for three different
people.
The following settings are stored as a single
memory preset:
Rposition of the seat, backrest and head
restraint
Rdriver's side: steering wheel position
Rdriver's side: position of the exterior mirrors
on the driver's and front-passenger sides
XMake sure that the SmartKey is in position 2
(Ypage 112) or that the respective door is
open.
XAdjust the seat (Ypage 74) and head restraint
(Ypage 74).
XOn the driver's side, adjust the steering wheel (Ypage 78) and the exterior mirrors
(Ypage 80).

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 remote control to recognize the sig-
nal during programming. Comparable with
Canadian law, American garage door openers
also have a built-in "interruption".
If you live in Canada or have difficulties pro-
gramming the garage door opener (regardless of
where you live) when using the programming
steps, proceed as follows:

XSimultaneously press transmitter button B
on the garage door remote control and hold
for 2 seconds. Then let go for 2 seconds,
press again and hold for 2 seconds.
XRepeat this sequence on transmitter button
B of the garage door remote control until the
frequency signal has been saved.
XIf the setup procedure is successful, indicator
lamp :flashes once slowly and goes out
after a few seconds.

If you have problems when programming the
integrated remote control, please note the fol-
lowing:
RCheck the transmitter frequency of garage
door remote control A(which can usually be
found on the back of the remote control).
The integrated remote control is compatible
with devices that have units which operate in the frequency range of 280 to 390 MHz.
Rreplace the batteries in garage door remote
control A. This increases the probability of
garage door remote control Asending a
strong and precise signal to the integrated
remote control on the rear-view mirror.
RWhen programming, hold garage door remote
control Aat varying distances and angles

from the transmitter button which you are
programming. Try various angles at a distance
between2and 12 inches (5 to 30 cm) or at the
same angle but at varying distances.
RIf there is another garage door remote control
for the same device, perform the program-
ming steps again using that garage door
opener. Before performing these steps, make
sure that new batteries have been installed in
the garage door remote control.
RAlign the antenna cable of the garage door
opener unit. This can improve signal trans-
mission.
