Make sure that you do not operate the ADS
switch or the vehicle level control system
when coupling/decoupling the trailer.
Observe the maximum permissible trailer
dimensions (width and length).
Most federal states and all Canadian
provinces require by law:
R safety chains between the towing vehicle
and the trailer. The chains should be cross-
wound under the trailer drawbar. They must
be fastened to the vehicle's trailer
coupling, not to the bumper or the axle.
Allow for enough play in the chains to
facilitate turning tight corners.
R a separate brake system for certain types
of trailer.
R a safety switch for braked trailers. Check
the specific legal requirements applicable
to your federal state.
If the trailer detaches from the towing
vehicle, the safety switch applies the
trailer's brakes.
! Do not connect the trailer's brake system
(if featured) to the hydraulic brake system
of the towing vehicle, as the latter is
equipped with an anti-lock brake system.
Doing so will result in a loss of function of
the brake systems of both the vehicle and
the trailer.

Vehicles with the AIRMATIC package:
with a trailer attached, the vehicle will
always remain at highway level. When
coupling up a trailer, please observe the
following:
R if highway level has not been set
manually, the vehicle will automatically
sink to highway level as soon as it
reaches a speed of 5 mph (8 km/h).
R high-speed level is not available.
These restrictions apply to all accessories
powered through a connection to the trailer
power socket of your vehicle, e.g. a bicycle
carrier.
Towing a trailer
There are numerous legal requirements
concerning the towing of a trailer, e.g. speed
restrictions. Make sure that your vehicle/
trailer combination complies with the local
requirements not only in your area of
residence but also at any location to which
you are traveling. The police and local
authorities can provide reliable information.
Please observe the following when towing a
trailer:
R To acquaint yourself with driving with a
trailer and with the resulting changes to
handling, you should practice cornering,
stopping and reversing in a traffic-free
location.
R Before driving, check:
- the trailer coupling
- the safety switch for braked trailers
- the safety chains
- the electrical connections
- the lights
- the wheels
R Adjust the exterior mirrors to provide an
unobstructed view of the rear section of the
trailer.
R If the trailer features electronically
controlled brakes, pull away the vehicle/

iCertain garage door openers are not
compatible with the integrated remote
control. If you experience difficulties with
the programming of the integrated remote
control, contact an authorized Mercedes-
Benz Center or call the following telephone
assistance service:

Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent
potential harm or damage. When
programming a garage door opener, the door
moves up or down. When programming a gate
operator, the gate opens or closes.
Do not use the integrated remote control with
any garage door opener that lacks safety stop
and reverse features as required by U.S.
federal safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the door
to stop and reverse - does not meet current
U.S. federal safety standards.
When programming a garage door opener,
park vehicle outside the garage.
Do not run the engine while programming the
integrated remote control. 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. All exhaust gas contains
carbon monoxide (CO), and inhaling it can
cause unconsciousness and possible death.

i Indicator lamp : flashes immediately
the first time that the transmitter button is
programmed. If this transmitter button has
already been programmed, indicator

once per second after 20 seconds have
elapsed.
XKeep the transmitter button depressed.XPoint transmitter button B of garage door
remote control A towards the transmitter
buttons on the rear-view mirror at a
distance of 2 to 12 inches (5 to 20 cm).
i The distance between garage door
remote control A and the integrated
garage door opener depends on the system
of the garage door drive. You might require
several attempts. You should test every
position for at least 20 seconds before
trying another position.

i If the garage door system works with a
rolling code, you must synchronize the
remote control integrated into the rear-
view mirror with the garage door system
receiver after programming.
You will find further information in the
garage door opening system's operating
instructions, e.g. the sections on
"Synchronizing the transmitter" or
"Registering a new transmitter". You can
also call the hotline mentioned above.
Notes on programming the remote
control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals a few seconds after broadcasting.
Therefore, these signals may not last long
enough for the integrated remote control to
recognize the signal during programming.
Comparable with Canadian law, some U.S.
garage door openers also have a built-in
"interruption".
If you live in Canada or have difficulties
programming the garage door opener
(regardless of where you live) when using the
programming steps (see above), proceed as
follows:
XPress transmitter button ( ;, = or ?) and
hold it down during the following steps until274FeaturesLoading, stowing and features

steps (see above).
Problems when programming
If you have problems when programming the
integrated remote control, please note the
following:
R Check the transmitter frequency of garage
door remote control A (which can usually
be found on the rear of the remote control).
The integrated remote control is
compatible with devices that operate at
frequencies between 280 and 390 MHz.
R Replace the batteries in garage door
remote control A. This increases the
likelihood of garage door remote
control A sending a strong and precise
signal to the integrated remote control on
the rear-view mirror.
R When programming, hold garage door
remote control A at varying distances and
angles from the transmitter button which
you are programming. Try different angles
at a distance of 2 to 12 inches (5 to 30 cm)
or the same angle at different distances.
R If there is another garage door remote
control for the same device, perform the
programming steps again using the remote
control. Before performing these steps,
make sure that new batteries have been
installed in the garage door remote control.
R Align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.
Opening or closing the garage door
Once programmed, the integrated remote
control will assume the function of the garage
door system's remote control. Please also
read the operating instructions for the garage
door system.
XTurn the SmartKey to position 2 in the
ignition lock.XPress transmitter button ;, = or ? in the
overhead control panel that you have
programmed to operate the garage door.
Garage door system with fixed code:
indicator lamp : lights up continuously.
Garage door system with rolling code:
indicator lamp : flashes briefly and then
lights up for approximately two seconds.
This is repeated for up to 20 seconds.
i The transmitter will transmit a signal for
as long as the transmitter button is being
pressed. The transmission will be halted
after a maximum of 20 seconds and
indicator lamp : will flash. Press the
transmitter button again, if necessary.
Clearing the remote control memory
XTurn the SmartKey to position 2 in the
ignition lock.XPress and hold transmitter buttons ;
and ? for approximately 20 seconds until
indicator lamp : flashes rapidly.
The memory is cleared.
i You should clear the remote control
memory before selling the vehicle.
