XPoint remote control A at a distance of
2 to 8 inches (5 to 20 cm) at buttons ;
to ? on the rear-view mirror.
i
The required distance between remote
control A and the integrated garage door
opener depends on the garage door drive
system. Several attempts might be
necessary. You should test every position
for at least 25 seconds before trying
another position.
XPress and hold button B on remote control
A until indicator lamp : lights up green.
If indicator lamp : lights up green or
flashes, then programming has been
successful.XRelease button B on remote control A for
the garage door drive system.
If indicator lamp : lights up red:
XRepeat the programming procedure for the
corresponding button on the rear-view
mirror. When doing so, vary the distance
between remote control A and the rear-
view mirror.
i If the indicator lamp flashes green after
successful programming, the garage door
system is operating on a rolling code. After
programming, you must synchronize the
garage door opener integrated in the rear-
view mirror with the receiver of the garage
door system.
Synchronizing the rolling code
Your vehicle must be within reach of the
garage door or exterior gate drive. Make sure
that neither your vehicle nor any persons/
objects are present within the sweep of the
door or gate.
Observe the safety notes when performing
the rolling code synchronization
( Y page 254).
XTurn the SmartKey to position 2 in the
ignition lock.XPress the programming button of the door
or gate drive (see the door or gate driveoperating instructions, e.g. under
"Programming of additional remote
controls").
i Usually, you now have 30seconds to
initiate the next step.
XPress previously programmed button ;,
= or ? of the integrated garage door
opener until the door starts to move.
The rolling code synchronization is then
complete.
Notes on programming the remote
control
Canadian radio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds.
Therefore, these signals may not last long
enough for the integrated garage door
opener. The signal is not recognized during
programming. Comparable with Canadian
law, some U.S. garage door openers are
designed to "time-out" in the same manner.
Proceed as follows:
R if you live in Canada
R if you have difficulties programming the
garage door opener (regardless of where
you live) when using the programming
steps
XPress and hold one of buttons ; to ? on
the integrated garage door opener.
After a short time, indicator lamp : starts
flashing yellow.XRelease the button.XPress button B of garage door remote
control A for two seconds, then release it
for two seconds.XPress button B again for two seconds.XRepeat this sequence on button B of
remote control A until indicator lamp :
lights up green.
If indicator lamp : turns red, repeat the
process.XContinue with the other programming
steps (see above).256FeaturesStowage and features
Problems when programming
If you are experiencing problems
programming the integrated garage door
opener on the rear-view mirror, take note of
the following instructions:
R Check the transmitter frequency of garage
door drive remote control A. This can
usually be found on the back of the remote
control.
The integrated garage door opener is
compatible with devices that have units
which operate in the frequency range of
280 to 390MHz.
R Replace the batteries in garage door
remote control A. This increases the
likelihood that garage door remote control
A will transmit a strong and precise signal
to the integrated garage door opener in the
rear-view mirror.
R When programming, hold remote control
A at varying distances and angles from the
button that you are programming. Try
various angles at a distance between
2 and 12 inches (5 to 30 cm) or at the same
angle but at varying distances.
R If another remote control for the same
garage door drive is available, repeat the
same programming steps with this remote
control. Before performing these steps,
make sure that new batteries have been
installed in garage door drive remote
control A.
R Note that some remote controls only
transmit for a limited amount of time (the
indicator lamp on the remote control goes
out). Press button B on remote control
A again before transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.
Opening/closing the garage door
After it has been programmed, the integrated
garage door opener performs the function of
the garage door system remote control.
Please also read the operating instructions
for the garage door system.XTurn the SmartKey to position 2 in the
ignition lock.XPress button ;, = or ? that you have
programmed to operate the garage door.
Garage door system with a fixed code:
indicator lamp : lights up green.
Garage door system with a rolling code:

i
The transmitter will transmit a signal for
as long as the button is pressed. The
transmission is halted after a maximum of
ten seconds and indicator lamp : flashes
yellow. Press button ;, = or ? again if
necessary.

garage door opener on the rear-view
mirror
XTurn the SmartKey to position 2 in the

i Make sure that you clear the memory of
the integrated garage door opener before

Floormat on the driver's side
GWARNING
Whenever you are using a floormat, make sure
there is enough clearance and that the
floormat is securely fastened.
The floormat should always be securely
fastened using the fastening equipment.
Before driving off, check that the floormat is
securely in place and adjust it if necessary. A
loose floormat could slip and hinder proper
functioning of the pedals.

cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.
! Make sure that the automatic
transmission is in position N when washing
your vehicle in a tow-through car wash. The
vehicle could be damaged if the
transmission is in another position.
! Make sure that:
R the side windows and roof are
completely closed.
R the blower for the ventilation/heating is
switched off (OFF button is depressed/
airflow control is turned to position 0).
R the windshield wiper switch is at position
0 .
The vehicle could otherwise be damaged.
After using an automatic car wash, wipe off
wax from the windshield and the wiper
blades. This will prevent smears and reduce
wiping noises caused by residue on the
windshield.
Washing by hand
In some countries, washing by hand is only
allowed at specially equipped washing bays.
Observe the legal requirements in all
countries concerned.
XDo not use hot water and do not wash the
vehicle in direct sunlight.XUse a soft sponge to clean.XUse a mild cleaning agent, such as a car
shampoo approved by Mercedes-Benz.XThoroughly hose down the vehicle with a
gentle jet of water.XDo not point the water jet directly towards
the air inlet.XUse plenty of water and rinse out the
sponge frequently.XRinse the vehicle with clean water and dry
thoroughly with a chamois.XDo not let the cleaning agent dry on the
paintwork.
When using the vehicle in winter, remove all
traces of road salt deposits carefully and as
soon as possible.
Power washers
GWARNING
Do not use power washers with circular-jet
nozzles (dirt grinders) to clean your vehicle, in
particular the tires. You could otherwise
damage the tires and cause an accident.
! Always maintain a distance of at least
11.8 in (30 cm) between the vehicle and the
power washer nozzle. Information about
the correct distance is available from the
equipment manufacturer.
Move the power washer nozzle around
when cleaning your vehicle.
Do not aim directly at any of the following:
R tires
R door gaps, roof gaps, joints, etc.
R electrical components
R battery
R connectors
R lights
R seals
R trim
R ventilation slots
Damaged seals or electrical components
can lead to leaks or failures.
! Do not use high-pressure cleaners if the
tank recess is open while you clean it. This
can cause damage to the seals or other
components.
Cleaning the wheels
! Do not use acidic wheel cleaning products
to remove brake dust. This could damage
wheel bolts and brake components.
