B970C01NF-AATAutomatic OperationThe FATC (Full Automatic Temperature Con-
trol) system automatically controls heating and
cooling as follows:
1. Push the "AUTO" switch. The indicator light
will illuminate confirming that the Face, Floor
and/or Bi-Level modes as well as the blower
speed and air conditioner will be controlled
automatically.
And, the air conditioning will operate if ambi-
ent temperature is higher than 34.7°F(1.5°C)
and automatically turns off if the ambient
temperature drops below 33.08°F(0.6°C).2. Turn the "TEMP" knob to set the desired
temperature.
The temperature will increase to the maxi-
mum "HI" by turning the knob clockwise.
The temperature will decrease to the mini-
mum "LO" by turning the knob counter-
clockwise.

With the "Fresh" mode selected, air enters the
vehicle from the outside and is heated or cooled
according to the function selected.
With the "Recirculation" mode selected, air from
within the passenger compartment will be drawn
through the heating system and heated or
cooled according to the function selected.
NOTE:It should be noted that prolonged opera-
tion of the heating system in "recirculation"
mode will give rise to fogging of the wind-
shield and side windows and the air within
the passenger compartment will become
stale. In addition, prolonged use of the air
conditioning with the "Recirculation" mode
selected may result in the air within the
passenger compartment becoming exces-
sively dry.Recirculation mode :
Air from witin the passenger compartment will
be drawn through the heating system and heated
or cooled according to the function selected.
Exhaust gas cutoff mode :
Air enters the vehicle from the outside.
But if exhaust gas enters the vehicle from the
outside, the exhaust gas cutoff mode ( ) is
automatically converted to the ( ) mode, to
prevent exhaust gas from entering the vehicle.
NOTE:It should be noted that prolonged opera-
tion of the heating system in recirculation
mode (
) will give rise to misting of the
windshield and side windows and the air
within the passenger compartment will
become stale. In addition, prolonged use of
the air conditioning with the recirculation
mode ( ) sele-cted may result in the air
within the passenger compartment becom-
ing excessively dry.

CAUTION:
o Replace the filter every 10,000 miles

frequent climate control air filter inspec-
tions and changes are required.
o When the air flow rate is suddenly de-
creased, the system should be checked
at an authorized dealer.

ANTENNAB870D01Y-AATGlass AntennaWhen the radio power switch is turned on while
the ignition key is in either the "ON" or "ACC"
position, your car will receive both AM and FM
broadcast signals through the antenna in the
rear window glass.
HNF2189-A
CAUTION:
o Do not clean the inner side of the rear
window glass with an abrasive type of
glass cleaner or use a scraper to remove
foreign deposits from the inner surface
of the glass as this may cause damage to
the antenna elements.
o Avoid adding metallic coatings to the
rear window glass, such as Ni, Cd, etc.
These can disturb receiving AM and FM
broadcast signals.

B880A01NF-AATSatellite Antenna (If Installed)The satellite antenna is installed on the roof of
your car to listen to a satellite radio broadcast.
This antenna is fixed by nut and it can not be
removed.NOTE:In the place like a tunnel where the satellite
broadcast signal can not be reached, the
ability of broadcast signal reception can be
affected and downed.

STEREO SOUND SYSTEMB750A02A-AATHow Car Audio Works
AM broadcasts can be received at greater
distances than FM broadcasts. This is because
AM radio waves are transmitted at low frequen-
cies. These long, low frequency radio waves
can follow the curvature of the earth rather than
travelling straight out into the atmosphere. In
addition, they curve around obstructions so that
they can provide better signal coverage. AM and FM radio signals are broadcast from
transmitter towers located around your city.
They are intercepted by the radio antenna on
your car. This signal is then received by the
radio and sent to your car speakers.
When a strong radio signal has reached your
vehicle, the precise engineering of your audio
system ensures the best possible quality repro-
duction. However, in some cases the signal
coming to your vehicle may not be strong and
clear. This can be due to factors such as the
distance from the radio station, closeness of
other strong radio stations or the presence of
buildings, bridges or other large obstructions in
the area.FM broadcasts are transmitted at high frequen-
cies and do not bend to follow the earth's
surface. Because of this, FM broadcasts gen-
erally begin to fade at short distances from the
station. Also, FM signals are easily affected by
buildings, mountains, or other obstructions.
These can result in certain listening conditions
which might lead you to believe a problem exists
with your radio. The following conditions are
normal and do not indicate radio trouble: Ionosphere
