injury.!
To avoid damaging the seals, do not trans-
port any objects with sharp edges which can
stick out of the tilt/sliding sunroof.
Do not open the tilt/sliding sunroof if there is
snow or ice on the roof, as this could result in
malfunctions.
The tilt/sliding sunroof can be opened or closed
manually should an electrical malfunction occur
(

1Cigarette lighter
Switch on the ignition (
page 37).
Push in cigarette lighter1.
The lighter will pop out automatically
when hot.
Power outlet
The power outlet is located in the rear pas-
senger compartment.
Switch on the ignition (
page 37).
Flip up cover and insert electrical plug
(cigarette lighter type).
!
The lighter socket can be used to accommo-
date 12 V DC electrical accessories (up to a
maximum of 85 W) designed for use with the
standard “cigarette lighter” plug type. Keep in
mind, however, that connecting accessories to
the lighter socket (for example extensive con-
necting and disconnecting, or using plugs that do
not fit properly) can damage the lighter socket.
With the socket damaged, the lighter may no
longer be able to be placed in the heating
(pushed-in) position, or the lighter may pop out
too early with the lighter not hot enough.
To help avoid damaging the cigarette lighter
socket, we recommend connecting 12 V DC
electrical accessories designed for use with a
standard “cigarette lighter” plug type to the 12 V
power outlets in your vehicle whenever possible.
i
The power outlet can be used to
accommodate 12 V DC electrical accessories
(e.g. air pump, auxiliary lamps) up to a maximum
of 180 W.
An additional power outlet is located on the left
side in the cargo compartment.

The Tele Aid system is operational provid-
ing that the vehicle’s battery is charged,
properly connected, not damaged and cel-
lular and GPS coverage is available.
The speaker volume of a Tele Aid call can
be adjusted when using the volume control
on the multifunction steering wheel. To
raise, press buttonæ and to lower,
press buttonçor use the volume knob
on your COMAND headunit.
To activate, press the SOS button, the
Roadside Assistance button• or

ing on the type of response required.
System self-check
Initially, after switching on the ignition,
malfunctions are detected and indicated
(the indicator lamps in the SOS button, the
Roadside Assistance button• and the
Information button¡ stay on longer
than 10 seconds or do not come on). The
message

The SOS button is located above the interior
rear view mirror (
page 295).
The Roadside Assistance button• and the
Information button¡ are located below the
center armrest cover (page 283).

The Tele Aid system utilizes the cellular net-
work for communication and the GPS (Global Po-
sitioning System) satellites for vehicle location. If
either of these signals are unavailable, the
Tele Aid system may not function and if this oc-
curs, assistance must be summoned by other
means.
