If the CD is not playing correctly, for any other
reason, try a known good CD.
If any error occurs repeatedly or if an error cannot
be corrected, contact your dealer. If the radio
displays an error message, write it down and
provide it to your dealer while reporting the
problem.
Using the Auxiliary Input Jack
Your radio system has an auxiliary input jack
located on the lower right side of the faceplate.
This is not an audio output; do not plug the
headphone set into the front auxiliary input jack.
You can however, connect an external audio
device such as an iPod, laptop computer, MP3
player, CD changer, or cassette tape player, etc. to
the auxiliary input jack for use as another source
for audio listening.
Drivers are encouraged to set up any auxiliary
device while the vehicle is in PARK (P). See
Defensive Driving on page 218 for more
information on driver distraction.
