Step 4: Using both hands, simultaneously
press hand-held remote control button B
and the desired signal transmitter button
(;, = or ?). Do not release the buttons
until step 5 is completed.
Indicator
lamp : will flash, first slowly and
then rapidly.
i Indicator lamp : flashes immediately
the first time the signal transmitter button
is programmed. If this button has already
been programmed, the indicator lamp will
start flashing after 20 seconds.
X Step 5: After indicator lamp : changes
from a slow to a rapidly flashing light,
release the hand-held remote control
button and the signal transmitter button.
X Step 6: Press and hold the just-trained
signal
transmitter button (;, = or ?) and
observe indicator lamp :.
If indicator lamp : stays on constantly,
programming is complete and your device
should activate when the respective signal
transmitter button ( ;, = or ?) is pressed
and released.
i If indicator lamp : flashes rapidly for
approximately

2 seconds and then turns to
a constant light, continue with
programming steps 8 through 12 as your
garage door opener may be equipped with
the “rolling code” feature.
X Step 7: To program the remaining two
signal
transmitter buttons, repeat the steps
above starting with step 3.
Rolling code programming
To
train a garage door opener (or other rolling
code devices) with the rolling code feature,
follow these instructions after completing the
“Programming” portion (steps 1 through 6) of
this text. For your convenience and to
complete the procedure faster, you might
want to have someone assist you. X
Step 8:
Locate the “training” button on the
garage door opener motor head unit.
i Exact
location and color of the button may
vary by garage door opener brand.
Depending on manufacturer, the “training”
button may also be referred to as “learn” or
“smart” button. If there is difficulty locating
the transmitting button, refer to the garage
door opener Operator’s Manual.
X Step 9: Press the “training” button on the
garage door opener motor head unit.
The “training light” is activated.
You have 30 seconds to initiate the
following two steps.
X Step 10: Return to the vehicle and firmly
press, hold for 2 seconds and release the
programmed

signal transmitter button (;,
= or ?).
X Step 11: Press, hold for 2 seconds and
release same signal transmitter button a
second time to complete the training
process.
i Some garage door openers (or other
rolling

code equipped devices) may require
you to press, hold for 2 seconds and
release the same signal transmitter button
a third time to complete the training
process.
X Step 12: Confirm the garage door
operation by pressing the programmed
signal transmitter button ( ;, = or ?).
X 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. 214

devices operating between 280-390 MHz
.
R Put a new battery in hand-held remote
control A. This will increase the likelihood
of the hand-held remote control sending a
stronger and more accurate signal to the
integrated remote control.
R While performing step 3, hold hand-held
remote control A at different lengths and
angles from the signal transmitter button
(;, = or ?) you are programming.
Attempt varying angles at the distance of 2
to 12 inches (5 to 30 cm) away or the same
angle at varying distances.
R 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.
R Straighten the antenna wire from the
garage door opener assembly. This may
help improve transmitting and/or receiving
signals.
i Certain types of garage door openers are
incompatible with the integrated remote
control. If you should experience further
difficulties with programming the
integrated remote control, contact an
authorized Mercedes-Benz Center, or call

i Possible differences between the
readings of a tire pressure gauge of an air
hose, e.g. gas station equipment, and the
vehicle’s control system can occur. The tire

locations, the reading on a tire pressure
gauge will be higher than the reading issued
by the vehicle’s control system. Do not
reduce the tire inflation pressure under
such circumstances.

inflation pressure values are monitored
already.
i With a spare wheel mounted, the system
may still indicate the tire inflation pressure
of the removed road wheel for some
minutes. If this happens, keep in mind that
the indicated value where the spare wheel
is mounted does not reflect the actual
spare tire inflation pressure.

Safety notes G
Warning!
Please do not forget that your primary
responsibility is to drive the vehicle. A driver’s
attention to the road must always be his/her
primary focus when driving. For your safety
and the safety of others, we recommend that
you pull over to a safe location and stop
before placing or taking a telephone call.
If you choose to use the telephone 15
while
driving, please use the hands-free device and
only use the telephone when road, weather
and traffic conditions permit. Some
jurisdictions prohibit the driver from using a
mobile telephone while driving a vehicle.
Only operate the COMAND 15
(Cockpit
Management and Data System) if road,
weather and traffic conditions permit.
Otherwise, you may not be able to observe
traffic conditions and could endanger yourself
and others.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second. Emission control
Certain systems of the engine serve to keep
the toxic components of the exhaust gases
within permissible limits required by law.
These systems will function properly only
when

maintained strictly according to factory
specifications. Any adjustments on the
engine should, therefore, be carried out only
by qualified Mercedes-Benz Center
authorized technicians.
Engine adjustments should not be altered in
any way. Moreover, the specified service
procedures must be carried out regularly according to Mercedes-Benz servicing
requirements. For details refer to the
Maintenance Booklet. G
Warning!
Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do

not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times. Maintenance
Notes
The Maintenance System in your vehicle
tracks the distance driven and the time
elapsed since the last maintenance service.
It

calculates other maintenance service work
required, and calls for the next maintenance
service accordingly.
We strongly recommend that you have your
vehicle serviced at an authorized Mercedes-
Benz Center. Have it serviced in accordance
with the Maintenance Booklet at the times
called for by the maintenance service
indicator.
i Failure to have the vehicle maintained in
accordance with the Maintenance Booklet
and maintenance service indicator at the
designated times/mileage will result in
vehicle damage not covered by the
Mercedes-Benz Limited Warranty.
15 Observe all legal requirements. 260
