nected to an antenna that is installed on
the outside of the vehicle.
The external antenna must be approved by

rized Mercedes-Benz Center for informa-
tion on the installation of an approved
external antenna. Refer to the radio trans-

step 3.Gate operator/Canadian programming
Canadian radio-frequency laws require
transmitter signals to “time-out” (or quit)
after several seconds of transmission
which may not be long enough for the
integrated signal transmitter to pick up the
signal during programming. Similar to this
Canadian law, some U.S. gate operators
are designed to “time-out” in the same
manner.
If you live in Canada or if you are having
difficulties programming a gate operator
(regardless of where you live) by using the
programming procedures, replace step 4
with the following:Step 4:

Continue to press and hold the
integrated signal transmitter button

has been learned. Upon successful
training, the indicator lamp1 will
flash slowly and then rapidly after
several seconds.
