GENERAL INFORMATION
INTRODUCTION
An audio system is standard factory-installed
equipment on this model, unless the vehicle is
ordered with an available radio delete option. Refer
to 8W-47 Audio System in Group 8W - Wiring Dia-
grams for complete circuit descriptions and diagrams.
NOTE: This group covers both Left-Hand Drive
(LHD) and Right-Hand Drive (RHD) versions of this
model. Whenever required and feasible, the RHD
versions of affected vehicle components have been
constructed as mirror-image of the LHD versions.
While most of the illustrations used in this group
represent only the LHD version, the diagnostic and
service
procedures
outlined
can
generally
be
applied to either version. Exceptions to this rule
have been clearly identified as LHD or RHD, if a
special illustration or procedure is required.
AUDIO SYSTEM
Several
combinations
of
radio
receivers
and
speaker systems are offered on this model. The stan-
dard equipment audio system includes an AM/FM
(RAL sales code) receiver, and speakers in two loca-
tions.
Following are general descriptions of the major
components in the standard and optional factory-in-
stalled audio systems. Refer to the owner’s manual in
the vehicle glove box for more information on the fea-
tures, use and operation of each of the available
audio systems.
DESCRIPTION AND OPERATION
RADIO
Available factory-installed radio receivers for this
model include an AM/FM (RAL sales code), an
AM/FM/cassette (RAS sales code), and an AM/FM/
CD/cassette/3-band
graphic
equalizer
(RAZ
sales
code). All factory-installed radio receivers are stereo
Electronically Tuned Radios (ETR), and include an
electronic digital clock function.
The radio can only be serviced by an authorized
radio repair station. Refer to the latest Warranty Pol-
icies and Procedures manual for a current listing of
authorized radio repair stations.
For more information on radio features, setting
procedures, and control functions refer to the owner’s
manual in the vehicle glove box.
IGNITION-OFF DRAW FUSE
All vehicles are equipped with an Ignition-Off
Draw (IOD) fuse that is removed when the vehicle is
shipped from the factory. This fuse feeds various
accessories that require battery current when the
ignition switch is in the Off position, including the
clock and radio station preset memory functions. The
fuse is removed to prevent battery discharge during
vehicle storage.
When removing or installing the IOD fuse, it is
important that the ignition switch be in the Off posi-
tion. Failure to place the ignition switch in the Off
position can cause the radio display to become scram-
bled when the IOD fuse is removed and replaced.
