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
headset usage by children should only occur
with adult supervision.

Multiple users
Simultaneous use of the rear-

operated almost entirely independently from
one another. However, there can be a conflict
in some menus if the two screens are used
simultaneously.
If the rear-compartment disc drive is being
used for both screens simultaneously,
selecting certain menus or settings on one of
the screens also affects the other screen.
The following functions affect both screens:
R changing playback options
R selecting a track (from a track list or folder)
R using the play, pause and stop functions
R fast forwarding/rewinding or scrolling
R calling up the DVD menu and navigating
within it
R setting the language, subtitles and camera

screen:
R audio and video functions as well as picture
settings

CD mode), the current setting is saved. If you
call up this operating mode again later, there
are two possibilities:
R the operating mode has been changed on
the other screen.
R the operating mode has not been changed.
In the first case, the operating mode appears
as it is on the other screen.
In the second case, the setting appears on the
screen as it was when you last exited the
