Cleaning the Video Screen
When cleaning the video screen,
use only a clean cloth dampened
with clean water. Use care when
directly touching or cleaning the
screen, as damage could result.
Rear Seat Audio (RSA)
System
Vehicles with this feature allow the
rear seat passengers to listen to
and control any of the music
sources: radio, CDs, DVDs, or other
auxiliary sources. The rear seat
passengers can control the same
music sources the front seat
passengers are listening to (dual
control, is available depending upon
radio) or a different source. For
example, rear seat passengers can
control and listen to a CD through
the headphones, while the driver
listens to the radio through the
speakers. The rear seat passengers
have control of the volume for each
set of headphones.
The radio functionality is controlled
by both the RSA and the front radio.
Only one band can be tuned to at
one time. Changing the band on the
RSA or the front radio will change
the band on the other system,
if they are both sourced to the radio.
The RSA can be used even when
the main radio is off. The front audio
system will display the headphone
icon when the RSA is on, and will
disappear from the display when it
is off.
Audio can be heard through wired
headphones (not included) plugged
into the jacks on the RSA. If the
vehicle has this feature, audio can
also be heard on Channel 2 of the
wireless headphones.
To listen to an iPod or portable
audio device through the RSA,
attach the iPod or portable audio
device to the front auxiliary input (if
available), located on the front audio
system. Turn the iPod on, then
choose the front auxiliary input with
the RSA SRCE button.
