Vehicle Damage Warnings
Also, in this book you will find these notices:
Notice:These mean there is something that could
damage your vehicle.
A notice will tell you about something that can damage
your vehicle. Many times, this damage would not be
covered by your warranty, and it could be costly. But the
notice will tell you what to do to help avoid the
damage.
When you read other manuals, you might see
CAUTION and NOTICE warnings in different colors or in
different words.
You’ll also see warning labels on your vehicle. They use
the same words, CAUTION or NOTICE.
Vehicle Symbols
Your vehicle has components and labels that use
symbols instead of text. Symbols, used on your vehicle,
are shown along with the text describing the operation
or information relating to a specific component, control,
message, gage or indicator.
If you need help figuring out a specific name of a
component, gage or indicator, reference the following
topics:
•Seats and Restraint Systems in Section 1

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 first. Figure out which radio you have in your vehicle,
find 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 has 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
Positions on page 2-17.Setting the Time for Radios without

on FM stations that broadcast RDS information.
With RDS, your radio can do the following:
•Seek to stations broadcasting the selected type of
programming
•Receive announcements concerning local and
national emergencies
•Display messages from radio stations
•Seek to stations with traffic announcementsThis system relies upon receiving specific information
from these stations and will only work when the
information is available. In rare cases, a radio station
may broadcast incorrect information that will cause
the radio features to work improperly. If this happens,
contact the radio station.
While you are tuned to an RDS station, the station
name or the call letters will appear on the display instead
of the frequency. RDS stations may also provide the
time of day, a program type (PTY) for current
programming, and the name of the program being
broadcast.
