{CAUTION:
This system provides you with a far greater
access to audio stations and song listings.
Giving extended attention to entertainment
tasks while driving can cause a crash and
you or others can be injured or killed.
Always keep your eyes on the road and
your mind on the drive — avoid engaging
in extended searching while driving.
Keeping your mind on the drive is important for
safe driving. Here are some ways in which you can
help avoid distraction while driving.
While your vehicle is parked:
Familiarize yourself with all of its controls.
Familiarize yourself with its operation.
Set up your audio system by presetting your
favorite radio stations, setting the tone, and
adjusting the speakers. Then, when driving
conditions permit, you can tune to your favorite
radio stations using the presets and steering
wheel controls if the vehicle has them.Notice:Before adding any sound equipment to
your vehicle, such as an audio system, CD
player, CB radio, mobile telephone, or two-way
radio, make sure that it can be added by
checking with your dealer. Also, check federal
rules covering mobile radio and telephone
units. If sound equipment can be added, it is
very important to do it properly. Added sound
equipment may interfere with the operation of
your vehicle’s engine, radio, or other systems,
and even damage them. Your vehicle’s systems
may interfere with the operation of sound
equipment that has been added.
Notice:The chime signals related to safety
belts, parking brake, and other functions of
your vehicle operate through the radio/
entertainment system. If that equipment is
replaced or additional equipment is added to
your vehicle, the chimes may not work. Make
sure that replacement or additional equipment
is compatible with your vehicle before installing
it. SeeAccessories and Modifications on
page 380.

The CD player can play the smaller 3 inch (8 cm)
single CDs with an adapter ring. Full-size CDs

handled. There may be an increase in skipping,
difficulty in nding tracks, and/or difficulty in loading
and ejecting. If these problems occur, check the

in the CD player. If a CD is recorded on a
personal computer and a description label is
needed, try labeling the top of the recorded CD
with a marking pen.Notice:If you add any label to a CD, insert
more than one CD into the slot at a time, or
