Audio Systems

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. 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" in the Index.

Setting the Time

Your radio may have a button marked with an H or HR
to represent hours and an M or MN to represent minutes.
Press and hold the hour button until the correct hour
appears on the display. AM or PM will also appear.
Press and hold the minute 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 for two seconds until RDS TIME appears on the
display. To accept the RDS time and to update the radio,
press the hour and minute buttons at the same time for
longer than two seconds. If the time is not available
from the station, NO UPDATE or NO UPDAT will
appear on the display instead.
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.
