Audio System(s)
Notice:Before you add any sound equipment to
your vehicle – like a tape player, CB radio, mobile
telephone or two-way radio – be sure you can add
what you want. If you can, it’s 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 improperly.So, before adding sound equipment, check with
your dealer and be sure to check federal rules
covering mobile radio and telephone units.
Your audio system has been designed to operate easily
and to give years of listening pleasure. You will get
the most enjoyment out of it if you acquaint yourself with
it rst. Figure out which radio you have in your vehicle,
nd out what your audio system can do and how to
operate all of its controls to be sure you’re getting the
most out of the advanced engineering that went into it.
Your vehicle may have a feature called Retained
Accessory Power (RAP). With RAP, you can play your
audio system even after the ignition is turned off.
See “Retained Accessory Power (RAP)” underIgnition
