Two-way radios and fa xequipment used with-
out low-reflection exterior aerials can inter-
fere with the vehicle's electronic sand thereby
jeopardise the operatin gsafety of the vehicle
and your safety. Therefore, you must only use
this equipment if it is correctly connected to
as eparate reflection-free exterior aerial. G
WARNING
Excessiv elevels of electromagnetic radiation
may cause damage to your health and the
health of others. Using an exterior aerial takes
int oa ccoun tcurren tscientific discussions
relatin gtothe possible health risk posed by
electromagnetic fields.
Mercedes-Benz recommends the use of an
approved exterior aerial. This ensures:
R optimal mobile phone reception quality in
the vehicle
R mutual influences between the vehicle
electronic sand mobile phones are mini-
mised
An exterior aerial has the following advan-
tages:
R it conducts the electromagnetic fields gen-
erated by awireless device to the exterior.
R the field strengt hinthe vehicle interior is
lower than in avehicle that does not have
an exterior aerial.

i If the indicator lamp flashes green after
successful programming, the garage door
system is using arolling code. After pro-
gramming, you must synchronise the
garage door opener integrated in the rear-
view mirror with the receiver of the garage
door system.
Synchronising the rolling code
Your vehicle must be within range of the
garage door or exterior gate drive. Make sure

Check the transmitter frequency of garage
door drive remote control A.This can usu-
ally be found on the back of the remote
control.
R Replace the batteries in garage door
remote control A.This increases the like-
lihood that garage door remote control A
will transmit astronga nd 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 the
button which you are programming. Try var-
ious angles at adistance between 5and
30 cm or at the same angle but at varying
distances.
R If there is another remote control for the
same garage door drive, perform the pro-
gramming steps again using this remote
control. 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 alimited period (the indicator lamp
on the remote control goes out). Press but-
ton Bon remote control Aagain before
