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.

Maintenance
Maintenance
We strongly recommend that you have
your vehicle serviced by your authorized
Mercedes-Benz Center, in accordance with
the Service Booklet at the times called for
by the FSS (Flexible Service System).
Failure to have the vehicle maintained in
accordance with the Service Booklet at the
designated times/mileage called for by
the FSS may result in vehicle damage not
covered by the Mercedes-Benz Limited
Warranty.
FSS will notify you when your next service
is due.
Approximately one month before your next
service is due, one of the following
messages will appear in the multifunction
display while you are driving or when you
switch on the ignition (example service A):SERVICE A IN XX DAYS
SERVICE A IN XX MILES (KM)
SERVICE A DUE NOW!
The type of service due is indicated in the
multifunction display:
9Minor service (A)
´Major service (B)
Clearing the service indicator
The service indicator is automatically
cleared

after ten seconds when you switch on
the ignition or when reaching the
service threshold while driving


after 30 seconds, once the suggested
service term has passed
You can also clear it yourself.

Press the reset button on the
instrument cluster (
page 22).
Service term exceeded
If you have exceeded the suggested
service term, you will see the following
message in the multifunction display:SERVICE A EXCEEDED BY XX DAYS
SERVICE A EXCEEDED BY XX MI (KM)An acoustic signal will also sound.
iThe interval between services depends
on your driving habits. A gentle driving
style, moderate engine speeds and the
avoidance of short-distance trips will
lengthen the interval between services.

This message appears in the multifunc-
tion display:SERVICE INTERVAL?
RESET WITH R BUTTON FOR 3 SEC.

To confirm, press reset button until you

iIf the battery is disconnected, the days
of disconnection will not be included in
the count shown by the service indica-
tor. To arrive at the true service
deadline, you will need to subtract
these days from the days shown in the
service indicator.
Do not confuse the service indicator
with the engine oil level indicator:.
iIf the service indicator was
inadvertently reset, have a
Mercedes-Benz Center correct it.
Only reset if the proper service has
been performed. Resetting the system
without performing proper service as
called for by the FSS will cause the FSS
to incorrectly determine the next
service interval which will result in
engine damage not covered by the
Mercedes-Benz Limited Warranty.
