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)” under
Ignition
Positions on page 2-18.
Setting the Time
Press and hold the HR button until the correct hour
appears on the display. Press and hold the MN button
until the correct minute appears on the display. The time
may be set with the ignition on or off.
To synchronize the time with an FM station broadcasting
Radio Data System (RDS) information, press and
hold the hour and minute buttons at the same time until
RDS TIME appears on the display. To accept this
time, press and hold the hour and minute buttons, at the
same time, for another 2 seconds. If the time is not
available from the station, NO UPDAT will appear on the
display.
RDS time is broadcast once a minute. Once you have
tuned to an RDS broadcast station, it may take a
few minutes for your time to update.
