DVD function can be viewed from the front
passenger side.
Use the SPLITVIEW remote control to operate
COMAND from the front passenger side.
Points to remember:
RYour vehicle may be equipped with
SPLITVIEW. The use of SPLITVIEW is
currently not permitted in the following
states: AL, CO, IL, LA, MA, MD, NH, PA, VA,
VT, WA, WI, and WV as well as in the
Canadian provinces Manitoba,
Newfoundland, New Brunswick, and Prince
Edward Island. The driver is responsible for
complying with ALL regional laws. If your
vehicle is registered in a state or province
where SPLITVIEW is not permitted, this
function must be deactivated. Please
consult an authorized Mercedes-Benz
center to verify if the use of SPLITVIEW is
permitted in your state/province.
RThe SPLITVIEW remote control can be used
to adjust the volume of the front-passenger
side headphones. Before putting on the
headphones, make certain that the volume
has not been set too high.
RYou can only use media from the driver's
and front-passenger sides separately if the
media are from different sources. Example:
on the driver's side, an audio CD is being
played on the DVD changer. This means
that on the front-passenger side, the DVD
changer cannot be used to play a different
medium, for instance a video DVD.
However, other media can be used at the
same time on the front-passenger side,
including radio, memory card, MUSIC
REGISTER, Media Interface, USB or AUX.
RIf you use the same medium on both sides,
you can both carry out the respective
settings.
RThere must be clear line of sight between
the headphones and the display so that
COMAND can optimally transmit music and
speech via the infrared signal on the front-
passenger's headphones. For this reason,
please also observe that the headphones
have left and right sides, and use them
correctly.
RUsing SPLITVIEW you can only use
entertainment functions separately, such
as audio and video functions.
RThe multifunction steering wheel can only
used for functions which relate to the
driver's side.
