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 remote control. 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 the buttons ;
to ? on the integrated garage door
opener.

turns red.XContinue with the other programming
steps (see above).214FeaturesStowage 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 remote control frequency of garage
door drive remote control A. This is
usually located 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 390 MHz.
R Change the batteries in garage door remote
control A. This increases the likelihood
that garage door remote control A will
send 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 which you are programming. Try
various angles at a distance of between 2
to 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 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.

Charge maintenance socket
The battery may drain if the vehicle is left
stationary for long periods. In this case,
Mercedes-Benz recommends attaching the
trickle charger to the charge maintenance
socket.
The charge maintenance socket is designed
solely for connecting a trickle charger. A
trickle charger can be obtained from an
authorized Mercedes-Benz Center, for
example.

SmartKey to position 2. Make sure that you
then leave the SmartKey in position 2. You
may otherwise damage the vehicle, the
transmission or the car wash.
Check the transmission position in the
instrument cluster.
! Use the E-SELECT lever to shift the
transmission to N before switching the
engine off. If you open the driver's or front-
passenger door, the transmission remains
in this position for up to 30 minutes if the
SmartKey is in the ignition, even if the
engine is switched off. If you do not shift
the transmission to N using the E-SELECT
lever beforehand, it shifts automatically to
parking position P and locks the wheels if
the driver's or front-passenger door is
opened and the engine is switched off. This
may damage the vehicle, the transmission
or the car wash.
Observe the information on maneuvering
( Y page 129).
! Before driving into an automatic car wash,
make sure that it is suitable for the
dimensions of the vehicle. In particular,
make sure that:
R there is enough ground clearance
between the vehicle underbody and the
guide rails of the automatic car wash.
R the clearance width of the automatic car
wash is sufficient, particularly the width
of the guide rails.
R you enter the automatic car wash
straight and in the center of the guide
rails in order to avoid damaging the tires
or wheel rims.
Fold in the exterior mirrors before the
vehicle is washed. The exterior mirrors
could otherwise be damaged.
! Make sure that:R
the side windows are fully closed.
R the ventilation/heating is switched off
(the OFF button has been pressed/the
airflow control is set to position 0).
R that the windshield wiper switch is in
position 0.
Otherwise, the vehicle might be damaged.
! In portal car washes, the windshield
wipers may be moved up the windshield by
the cleaning brushes when the ignition is
switched off.
Set the Start/Stop button to key position
2 to reset the windshield wipers to their
original position.
! Vehicles with a matte finish:
Do not use wash programs with a hot wax
treatment under any circumstances.
After using an automatic car wash, wipe off
wax and drying agents from the windshield
and the wiper blades. This will prevent smears
and reduce wiping noises caused by residue
on the windshield.
Power washersGWARNING
Using power washers with circular-jet nozzles
(dirt grinders) may cause damage to the
vehicle, in particular to the tires.
Using damaged tires results in an increased
risk of accident. A sudden loss of tire pressure
while you are driving may cause you to lose
control of your vehicle, cause an accident and
injure yourself and others.
! Maintain a minimum distance of
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.
