sources, such as on analog AM radio or
in Weather Band.
R In the event of poor radio reception
quality, e.g. inside a tunnel, you should
switch off Logic 7 ®
, as a dynamic switch
from Stereo to Mono could occur,
resulting in temporary sound distortion.
R With some stereo recordings, the
resulting sound may deviate from
conventional stereo playback.

SPLITVIEW enables the driver and front
passenger to use separate COMAND
functions at the same time. Two different
displays appear in the COMAND screen. For
example, a Navigation display is only viewable
form the driver’s seat while a DVD Video
display is only viewable from the front
passenger’s seat.
COMAND is operated via SPLITVIEW from the
front passenger seat using the SPLITVIEW
remote control and the special wireless,
infrared headphone. You may also use a wired
headphone via the 3.5 mm socket in the front
passenger footwell.
For information about using the remote
control, see ( Y page 81).
For information about using the headphone,
see ( Y page 82).
Depending on the production date of your
vehicle, it may be equipped with SPLITVIEW.
At the time of this printing, the use of
SPLITVIEW is NOT allowed in the following US
states (AL, AZ, CO, IL, LA, MA, MD, NH, PA,
VA, VT, WA, WI, and WV) or Canadian
provinces (Manitoba, Newfoundland, New
Brunswick, and Prince Edward Island).
SPLITVIEW must NOT be operated in these
states or provinces. The driver is responsible
for observing ALL local statutory provisions.
If your vehicle is registered in a non-approved
state or province, then the feature will need
to be deactivated. Contact your authorized
Mercedes-Benz dealer to verify if SPLITVIEW
is allowed in your state or province.

control. Make sure the volume is not set
too high before putting on a headphone.
RThe DVD changer can playback only one
media source at a time. Example: if the
driver is playing an audio CD, the front
passenger can not play a different medium
(e.g. DVD video) from the DVD changer.
However, it is possible for the front
passenger to play media from radio,
memory card, MUSIC REGISTER, media
interface, USB, AUX or Rear Seat
Entertainment System.
RWhen driver and front passenger are using
the same medium, each can select
individual settings for that medium.
RCOMAND transmits music and voice to the
wireless headphone for the front passenger
side via infrared signal. The headphone and
the display must have visual contact. This
provides best possible transmission of the
infrared signal to the headphone. Please
note that the headphone has a left and right
side and must be used accordingly.
RWhen SPLITVIEW is on, the front passenger
can operate audio or video functions only.
RThe multifunction steering wheel lets you
operate functions for the driver’s side only.

Rear Seat Entertainment SystemGObserve Safety notes, see page 76.GWarning!
The driver should not wear a Rear Seat
Entertainment headphone while operating the
vehicle under any circumstances. The use of
a headphone while driving the vehicle could
drastically impair the ability to react to audible
traffic conditions (e.g. emergency sirens from
police/fire/ambulance, another car’s horn,
etc.).
GWarning!
When not in use, headphones or external
video sources should be stored in a safe
location (e.g. one of the vehicle’s storage
compartments) so that they are not loose
within the passenger compartment during
braking, vehicle maneuvers or a traffic
accident. Objects moving within the
passenger compartment could cause serious
personal injury to vehicle occupants.
GWarning!
Due to a potential choking hazard, wired
headphone usage by children should only
occur with adult supervision.
You can operate the Rear Seat Entertainment
System via the remote controls ( Y page 81)
that come with the vehicle.
The playback of audio and video sources with
the Rear Seat Entertainment System is
identical to playback with the COMAND to a
large extent.
The COMAND and the Rear Seat
Entertainment System can be operated
simultaneously almost independent of each
other. However, some menus may cause
conflicts when the systems are used by
multiple users. Conflicts can occur between
the rear screens as well as COMAND and the
Rear Seat Entertainment System.
Remote controls for Rear Seat
Entertainment System
The Rear Seat Entertainment System
contains two remote controls for the rear
passenger compartment.
For information on using the remote controls,
see ( Y page 81).
Headphones for Rear Seat
Entertainment System
The Rear Seat Entertainment System
contains two headphones for the rear
