OPERATION
For operation of the factory installed standard and
optional radios with cassette or compact disc player,
refer to the Sound Systems Operating Instructions in
the Owners Manual supplied with the vehicle.
The vehicles are shipped with fuse 13 removed
from the junction block. The fuse replaces the igni-
tion-off draw (IOD) connector. Fuse 13 is a ten amp
fuse. When removed, it prevents the battery from
discharging during storage. For specific wiring and
location, refer to Group 8W, Wiring Diagrams.
4 DISC IN-DASH CD CHANGER
DESCRIPTION
The 4 Disc In-Dash CD Changer (if equipped) is
located in the existing cubby bin. It is a cartridge-
less changer controlled by the radio and allows the
occupants to load up to four discs at one time.
OPERATION
Due to its compact design, the CD changer can
only carry out one operation at a time. For example,
you can not load a new disc while playing another at
the same time. Each operation happens sequentially.
The radio unit provides control over all features of
the CD changer with the exception of the CD load
and eject functions, which are controlled by buttons
located on the front of the CD changer. All features
you would expect, such as Disc Up/Down, Track
Up/Down, Random and Scan are controlled by the
radio, which also displays all relevant CD changer
information on the radio display.
The CD changer contains a Load/Eject button and
an indicator light for each of the four disc positions.
The individual light indicates whether a CD is cur-
rently loaded in that particular chamber of the CD
changer. Pressing the individual Load/Eject button
for a particular chamber will eject a disc currently
present in that chamber. If the chamber is currently
empty, actuating the Load/Eject button will position
that chamber to receive and load a new disc in that
chamber.
INTERFERENCE ELIMINATION
DESCRIPTION
Some components used on the vehicles are
equipped with a capacitor to suppress radio fre-
quency interference/static.
Ground straps are mounted from the engine to
each shock tower. The ground straps should be
securely tightened to assure good metal to metal con-
tact.
OPERATION
Capacitors are mounted in various locations inter-
nal to the generator, instrument cluster and wind-
shield wiper motor.
Ground straps conduct very small high frequency
electrical signals to ground and require clean large
surface area contact. The radio grounds to the floor
pan through a ground strap which bolts to the back
of the radio from the instrument panel wire harness.
REAR WINDOW ANTENNA
DESCRIPTION
The integrated rear window antenna incorporates
the rear window defogger and a electronic module to
receive radio signals. The module is located in the
right C-pillar behind the trim panel.
OPERATION
The AM and FM signals are received via isolated
unheated lines along the top of the rear window.
NOTE: If aftermarket window shading is added, it
cannot be of the metallic type. Metallic type window
shading can cause poor radio reception.
NOTE: If an accessory cellular phone glass mount
antenna is installed, it should only be installed so
as to avoid contact with any of the rear glass grid
lines.
