Headphone 
GWarning!
The driver should not wear a 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.

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

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
