Warning!
G
In the case of an accident liquid electrolyte
may escape from the mirror housing if the
mirror glass breaks.
Electrolyte has an irritating effect. Do not
allow the liquid to come into contact with
eyes, skin, clothing, or respiratory system.
In case it does, immediately flush affected
area with water, and seek medical help if
necessary.Warning!
G
Exercise care when using the passen-
ger-side exterior rear view mirror. The mirror
surface is convex (outwardly curved surface
for a wider field of view). Objects in mirror
are closer than they appear. Check your
interior rear view mirror or glance over your
shoulder before changing lanes.
!Electrolyte drops coming into contact
with the vehicle paint finish can be
completely removed only while in the
liquid state by applying plenty of water.

Programming or reprogramming the
integrated remote control
Step 1:
Switch on ignition.
Step 2:

If you have previously programmed an
integrated signal transmitter button
and wish to retain its programming,
proceed to step 3. Otherwise, press
and hold the two outer signal transmit-
ter buttons2 and4 and release
them only when the indicator light
begins to flash after approximately
20 seconds (do not hold the button for
longer than 30 seconds). This proce-
dure erases any previous settings for
all three channels and initializes the
memory. If you later wish to program a
second and/or third hand-held trans-
mitter to the remaining two signal
transmitter buttons, do not repeat this
step and begin directly with step 3.
iCertain types of garage door openers
are incompatible with the integrated
opener. If you should experience
difficulties with programming the
transmitter, contact your 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.
iFor operation in the USA only:
This device complies with Part 15 of
the FCC Rules. Operation is subject to
the following two conditions:
(1) This device may not cause harmful
interference, and
(2) this device must accept any
interference received, including

undesired operation.
Any unauthorized modification to this
device could void the user’s authority

Useful features
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
(2, 3 or4) while you press and
re-press (“cycle”) your hand-held
remote control transmitter6 every
two seconds 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. Operation of integrated remote control

Switch on ignition.

Select and press the appropriate
integrated signal transmitter button
(2, 3 or4) to activate the remote
controlled device.
The integrated remote control trans-
mitter continues to send the signal as
long as the button is pressed – up to
20 seconds.

236 Controls in detailUseful featuresErasing the integrated remote control
memory
Switch on ignition.

Simultaneously hold down the signal
transmitter buttons2 and 4, for
approximately 20 seconds, until the
indicator lamp1 flashes rapidly. Do
not hold for longer than 30 seconds.
The codes of all three channels are
erased.Reprogramming a single integrated
signal transmitter button
To program a device using a signal trans-
mitter button previously trained, follow
these steps:

Press and hold the desired signal
transmitter button (2, 3 or4).
Do not release the button.

The indicator lamp will begin to flash
after 20 seconds. Without releasing
the integrated signal transmitter
button, proceed with programming
starting with step 3.
iIf you sell your vehicle, erase the codes
of all three channels.
