Step 12:
Confirm the garage door operation by
pressing the programmed signal trans-
mitter button (2, 3 or4).
Step 13:
To program the remaining two signal
transmitter buttons, repeat the steps
above starting with 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:
Press and hold the signal transmitter
button (2, 3 or4). Do not release
this button until it has been successful-
ly trained.
While still holding down the signal
transmitter button (2, 3 or4),
“cycle” your hand-held remote control
button6 as follows: Press and hold
button6 for 2 seconds, then release
it for 2 seconds, and again press and
hold it for 2 seconds. Repeat this se-
quence on the hand-held remote con-
trol until the frequency signal has been
learned. Upon successful training, the
indicator lamp1 will flash slowly and
then rapidly after several seconds.
Proceed with programming step 5 and
step 6 to complete.
iSome garage door openers (or other
rolling code equipped devices) may
require you to press, hold for 2 seconds
and release the same signal transmit-
ter button a third time to complete the
training process.

Erasing the integrated remote control
memory
Switch on the ignition (
page 36).
Simultaneously press and hold down
the outer signal transmitter buttons2
and 4, for approximately 20 seconds,
until the indicator lamp1 flashes rap-
idly. Do not hold for longer than
30 seconds.
The codes of all three channels are
erased.Programming tips
If you are having difficulty programming
the integrated remote control, here are
some helpful tips:
Check the frequency of the hand-held
remote control5 (typically located on
the reverse side of the remote). The in-
tegrated remote control is compatible
with radio-frequency devices operating
between 288-399 MHz.
Put a new battery in the hand-held re-
mote control5. This will increase the
likelihood of the hand-held remote con-
trol sending a faster and more accurate
signal to the integrated remote control.
While performing step 3, hold the
hand-held remote control6 at differ-
ent lengths and angles from the signal
transmitter button (2, 3 or4) you
are programming. Attempt varying an-
gles at the distance of 2 to 5 inches
(5 to 12 cm) away or the same angle at
varying distances.
If another hand-held remote control is
available for the same device, try the
programming steps again using that
other hand-held remote control. Make
sure new batteries are in the hand-held
remote control before beginning the
procedure.
Straighten the antenna wire from the
garage door opener assembly. This
may help improve transmitting and/or
receiving signals.
iIf you sell your vehicle, erase the codes
of all three channels.
iCertain types of garage door openers
are incompatible with the integrated
remote control. If you should experi-
ence further difficulties with program-
ming the integrated remote control,
contact an authorized Mercedes-Benz
Center, or call Mercedes-Benz
Customer Assistance Center (in the
USA only) at 1-800-FOR-MERCedes, or
Customer Service (in Canada) at
1-800-387-0100.
