Important safety notes G
WARNING
Whe nyou load the roof, the center of gravity
of the vehicle rises and the driving
characteristics change. If you exceed the
maximum roof load, the driving
characteristics, as well as steering and
braking, will be greatly impaired. There is a
risk of an accident.
Never exceed the maximum roof load and
adjust your driving style.
! Mercedes-Benz recommends that you
only use roof carriers that have been tested
and approved for Mercedes-Benz vehicles.
This helps to prevent damage to the
vehicle.
Position the load on the roof carrier in such
a way that the vehicle will not sustain
damage even when it is in motion.
Depending on the vehicle equipment,
ensure that when the roof carrier is
installed you can:
R raise the sliding sunroof fully
R open the panorama roof with power tilt/
sliding panel fully
R open the tailgate fully
The maximum roof load is 220 lbs(100 kg). Attaching the roof carrier X

Important safety notes G
WARNING
When you operate or program the garage door
with the integrated garage door opener,
persons in the range of movement of the
garage door can become trapped or struck by
the garage door. There is arisk of injury.
When using the integrated garage door
opener, always make sure that nobody is
within the range of movement of the garage
door. G
WARNING
Combustion engines emit poisonous exhaust
gases such as carbo nmonoxide. Inhaling
these exhaust gases leads to poisoning. There
is a risk of fatal injury. Therefore never leave
the engine running in enclosed spaces
without sufficient ventilation.
The HomeLink ®
garage door opener
integrated in the rear-view mirror allows you
to operate up to three different door and gate
systems.
Only operate garage doors using the
integrated garage door opener if:
R they are equipped with a safety stop and
reverse feature, and
R they conform to the current U.S. safety
standards.
When programming a garage door opener,
park vehicle outside the garage.
i Certain garage door drives are
incompatible with the integrated garage door opener. If you have difficulty
programming the integrated garage door
opener, contact an authorized Mercedes-
Benz Center.

Observe the "Important safety notes"
(Y

Notes on programming the remote
control
Canadia nradio frequency laws require a
"break" (or interruption) of the transmission
signals after broadcasting for a few seconds.
Therefore, these signals may no tlast long
enough for the integrated garage door
opener. The signal is no trecognized during
programming. Comparable with Canadian
law, some U.S.g arage door openers also
feature a "break".
Proceed as follows:

garage door opener (regardless of where
you live) when using the programming

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 001C.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
280to 433MHz.
R Replace the batteries in garage door
remote control 001C.This increases the
likelihood that garage door remote control
001C will transmit a stronga nd precise signal
to the integrated garage door opene rinthe
rear-view mirror.
R When programming, hold remote control
001C at varying distances and angles from the
button that you are programming. Try
various angles at a distance between 2and
12 inches (5to 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
001C.
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 001Don remote control
001C again before transmission ends.
R Align the antenna cable of the garage door
opener unit. This can improve signal
reception/transmission.

Automatic car wash G
WARNING
Braking efficiency is reduced after washing
the vehicle. There is a risk of an accident.
After the vehicle has been washed, brake
carefully while paying attention to the traffic
conditions until full braking power is restored.
! If DISTRONIC PLUS or the HOLD function
is activated, the vehicle brakes
automatically in certain situations. To
prevent damage to the vehicle, deactivate
DISTRONIC PLUS and the HOLD function in
the following or other similars ituations:
R when towing the vehicle
R in the car wash
! Neve rclean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
! Make sure that:
R the side windows and the sliding sunroof
are fully closed.
R the ventilation/heating is switched off
(the OFF button has been pressed).
R the windshield wiper switch is in position
0.
Otherwise, the vehicle might be damaged.
! In car washes with a towing mechanism,
make sure that the automatic transmission is in transmission position
N, otherwise the
vehicle could be damaged.
R Vehicles with a SmartKey:
Do not remove the SmartKey from the
ignition lock. Do not open the driver's
door or front-passenger door when the
engine is switched off .Otherwise, the
automatic transmission selects park
position Pautomatically and locks the
wheels .You can prevent this by shifting
the automatic transmission to N
beforehand.
R Vehicles with KEYLESS-GO:
Do not open the driver's door or front-
passenger door when the engine is
switched off. Otherwise, the automatic
transmission selects park position P
automatically and locks the wheels.
Observe the following to make sure that the
automatic transmission stays in position N:
X Make sure the vehicle is stationary and the
ignition is switched off.
X Turn the SmartKey to position
2(Y page 157) in the ignition lock.
Use the SmartKey instead of the Start/
Stop button on vehicles with KEYLESS-GO.
X Depress and hold the brake pedal.
X Shift the automatic transmission to
position N.
X Release the brake pedal.
X Release the electric parking brake.
X Switch off the ignition and leave the
