GMC XL Automobile User Manual


 
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 GM 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.
See Accessories and Modifications on page 5-3.
Your vehicle has a feature called Retained Accessory
Power (RAP). With RAP, the audio system can be
played even after the ignition is turned off. See Retained
Accessory Power (RAP) on page 2-20 for more
information.
Setting the Time
The 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 appear on
the display for morning or evening hours. Press and
hold the minute button until the correct minute appears
on the display. The time can 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
UPDATED and the clock symbol appear on the
display. If the time is not available from the station,
NO UPDAT will appear on the display.
RDS time is broadcast once a minute. After tuning to an
RDS broadcast station, it may take a few minutes for
the time to update.
