66AntennaThe antenna for the audio system is integral to the
rear window glass. The AM portion of the antenna
uses the same pattern of lines as the grid for the
rear defroster. The FM portion of the antenna uses
the top three lines on the glass, which are indicated
by the word ªRADIO.ºCommon Radio Reception
ConditionsSeveral conditions prevent FM reception from being
completely clear and noise-free, such as the
following:Distance/StrengthThe strength of the FM signal is directly related to
the distance the signal must travel. The listenable
range of an average FM signal is approximately 24
miles (40 km). Beyond this distance, the radio is
operating in a ªfringeº area and the signal becomes
weaker. Also, ªSignal Modulationº is used by somestations to increase their ªloudnessº relative to other
stations. The difference in loudness can be a result
of signal modulation as well as signal strength.
TerrainThe terrain (hilly, mountainous, tall buildings) of the
area over which the signal travels may prevent the
FM signal from being noise-free.
If there is a building or large structure between the
antenna and station, some of the signal ªbendsº
around the building, but certain spots receive almost
no signal. Moving out of the ªshadowº of the
structure will allow the station to return to normal.
When the radio waves are reflected off objects or
structures, the reflected signal cancels the normal
signal, causing the antenna to pick up noise and
distortion. Cancellation effects are most prominent
in metropolitan areas, but also can become quite
severe in hilly terrain and depressed roadways.

To minimize these conditions, a stereo/mono blend
circuit has been incorporated into this system. This
feature automatically switches a weak stereo signal
to a clearer monaural signal, which improves the
quality of reception.
Several sources of static are normal conditions on
AM frequencies. These can be caused by power
lines, electric fences, traffic lights and
thunderstorms.
Another reception phenomenon isStrong Signal
Capture and Overload. This can occur when
listening to a weak station and when passing
another broadcast tower. The close station may
capture the more distant station, although the
displayed frequency does not change. While passing
the tower, the station may switch back and forth a
few times before returning to the original station.
When several broadcast towers are present
(common in metropolitan areas), several stations
may overload the receiver, resulting in considerablestation changing, mixing and distortion.
Automatic gain control circuitry for both AM and
FM bands has been incorporated into this system to
reduce strong signal capture and overload.
All About Radio FrequenciesThe Federal Communications Commission (FCC)
and the Canadian Radio Telecommunications
Commission (CRTC) establish the frequencies that
AM and FM radio stations may use for their
broadcasts. The allowable frequencies are, AM: 530,
540...1600, 1610 kHz in 10 kHz steps; FM: 87.9,
88.1...107.7, 107.9 MHz in 0.2 MHz steps.
Not all frequencies will be assigned to a given area.
This radio will tune to each of these frequencies
using manual tune and no fine tuning is necessary
as radio stations may not use other frequencies.
Some FM radio stations advertise a ªrounded-offº
frequency which is not the frequency they actually
broadcast on. For example, a radio station that is

68assigned a frequency of 98.7 MHz may call itself
ªRadio 99º even though 99.0 MHz is not an
allowable FM broadcast frequency.Important Warranty and Service

Controls and FeaturesThe Climate Control SystemElectronic Automatic Temperature
Control SystemThe Electronic Automatic Temperature Control
(EATC) module is located at the center of the
instrument panel and operates only when the key is
in the ON position.The EATC feature maintains the temperature you
select and automatically controls the airflow for
your comfort. It also allows you to override the
automatic operation with manual override buttons.

70The automatic temperature control system
To turn your EATC on, push the AUTOMATIC
button or any of the six override buttons along the
bottom of the control.
To turn your EATC off, press the OFF button.
When the system is off, the display window will be
blank (dark).
If you select AUTOMATIC, the system will
automatically determine fan speed and airflow
location. If an override button is selected, your
selection determines airflow location only. Fan
speed remains automatic unless you override it by
rotating the vertical thumbwheel located at the
extreme right of the control panel.
To change the temperature in the display window,
select any temperature between65ÊF(18ÊC) and
85ÊF(29ÊC)using the BLUE (cooler) or RED
(warmer) buttons. The Electronic Automatic
Temperature Control will do the rest.

If you want continuous maximum cooling, push the
BLUE button until60ÊF(16ÊC) isshown in the
display window. Your EATC will cool at maximum
and disregard the60ÊF(16ÊC)setting until you
select a warmer temperature with the RED button.
If you want continuous maximum heating, push the
RED button until90ÊF(32ÊC) isshown in the
display window. Your EATC will provide maximum
heat regardless of the90ÊF(32ÊC)setting until you
select a cooler temperature with the BLUE button.
The display window tells you how the system is
operating. It will indicate the selected temperature
and the operating function you have chosen; AUTO
or one of the six manual overrides. It will also
indicate manual (thumbwheel) control of the fan
speed with the
Hsymbol. The display window
with all possible displays and their positions are
shown here. Normally not all are shown at the
same time but are included here to familiarize you
with the names and symbols.
Automatic operationPush the AUTOMATIC button and select the
desired temperature. The selected temperature and
AUTO will be shown in the display window. The
EATC will automatically heat or cool to achieve the
set temperature. Under normal conditions, your
EATC will need no additional attention.

72When in AUTOMATIC and weather conditions
require heat, air will be sent to the floor. But, a
feature is included in your EATC to prevent
blowing cold air to the floor if the engine coolant is
not warm enough to allow heating. In 3-1/2
minutes or less, the fan speed will start to increase
and the airflow will change to the floor area.
If unusual conditions exist (i.e., window fogging,
etc.), the six manual override buttons allow you to
select special air discharge locations. A thumbwheel
allows you to adjust the fan speed to suit your
needs.
Temperature selectionThe RED and BLUE buttons at the upper left of the
Control are for temperature selection. The RED
Button will increase the set temperature and the
BLUE Button will lower the set temperature.
Pressing a button and releasing it will change the
set temperature one degree. Holding either button
in will rapidly change the temperature setting in
one degree increments to either65ÊF(18ÊC)
(BLUE) or85ÊF(29ÊC)(RED). Then, the set
temperature will jump 5 Ê and stop at either60ÊF
(16ÊC)which is maximum cooling or90ÊF(32ÊC)
which is maximum heating. When you select60ÊF
(16ÊC) or90ÊF(32ÊC), the fanwill go to HI speed
for maximum air flow.
The average temperature range used is between
68ÊF(20ÊC) and78ÊF(26ÊC).Changing the
temperature setting by several degrees outside this
range or overriding to60ÊF(16ÊC) or90ÊF(32ÊC)
will not speed up the heating or cooling process.

Fan speed and thumbwheelYour EATC automatically adjusts the fan speed to
the existing conditions. You must push
AUTOMATIC for automatic fan speed operation. To
control the fan speed yourself, use the thumbwheel
which will cancel the automatic fan speed control.
The thumbwheel is located at the extreme rightside of the EATC control panel. It is a vertical
control marked with a fan symbol. Rotate up for HI
and down for LO speeds.
When you move the thumbwheel, the fan speed
will go to manual control. The display window will
show the
Hsymbol in the upper left corner along
with the selected temperature and operating
function.

74You can override the fan speed at any time. If you
use the thumbwheel to override the fan speed, the
EATC will continue to control the temperature but
you control the fan speed. To return to auto fan
control, press the AUTOMATIC button. If you are
operating in one of the override functions (FLOOR,
MAX A/C, etc.), automatic fan control will
continue unless you rotate the fan thumbwheel. Toreturn to automatic fan control, press the
AUTOMATIC button. The EATC will return to
Automatic operation. If you want to return to any
override function, press the button for that function.
The fan speed will continue to be automatically
controlled.
Manual override buttonsYour EATC has six buttons which allow you to
make special selections. The buttons are located
along the bottom edge of the EATC control and
allow you to determine where the air will be
discharged. Pressing any override button changes
the air discharge location only. It does not affect
the ability of the system to control temperature or
the fan speed. Return to fully Automatic operation
by pushing the AUTOMATIC button.

MAX A/C button
The MAX A/C feature allows for faster cooling
because air is drawn from inside the vehicle. Using
inside air causes the fan to sound louder which is
normal for this selection. The Display window will
change to indicate60ÊF(16ÊC) and MAXA/C. The
fan will run and the airflow will be from the
instrument panel registers. To exit and return to the
previous temperature, push AUTOMATIC or any of
the other five override buttons.
VENT button
Push this button to select outside air through the
instrument panel registers. The display window will
show the set temperature and VENT to the lower
right of the temperature. Your EATC will heat the
air if the temperature you have selected is warmer
than the outside air coming into the vehicle.
However, the air will NOT be cooled regardless of
the temperature setting.PNLOFLR button
Push this button to get air from the floor and
instrument panel registers at the same time. The
display will show the set temperature and the
words PNL and FLR. Depending on the selected
temperature, the air will be automatically heated or
cooled.
FLOOR button
Airflow will be to the floor when the FLOOR
button is pressed. The display window will show
the set temperature and FLR to the left of the
temperature. The air cannot be cooled in the FLR
position, only heated. Fan speed will be automatic
unless manually controlled. If you override the fan
speed and wish to return to automatic fan control,
push AUTOMATIC. Then, again select FLOOR for
airflow to the floor.
