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:o It should be noted that prolonged opera-
tion of the heating system in "recircula-
tion" mode will give rise to fogging 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 "Re-
circulation" mode selected may result in
the air within the passenger compart-
ment becoming excessively dry.
o When the ignition switch is turned "ON"
the air intake control will change to " "
mode (regardless of switch position).
This is normal operation. The air intake
control operates in "AUTO" mode when
turning the ignition to the ON position if
the "AUTO" mode was used before shut-
ting off the engine.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:o It should be noted that prolonged opera-
tion of the heating system in recircula-
tion mode ( ) will give rise to misting
of the windshield and side windows and
the air within the passenger compart-
ment will become stale. In addition, pro-
longed use of the air conditioning with
the recirculation mode ( ) sele-cted
may result in the air within the passenger
compartment becoming excessively dry.
o When the ignition switch is turned "ON",
the air intake control will change to
"Fresh" mode (regardless of switch po-
sition). This is normal operation. The air
intake control operates in "AUTO" mode
when turning the ignition to the ON
position if the "AUTO" mode was used
before shutting off the engine.

CAUTION:
o Replace the filter every 10,000 miles

If the car is being driven in severe condi-
tions such as dusty, rough roads, more
frequent air conditioner filter inspec-
tions and changes are required.
o When the air flow rate is suddenly de-
creased, it must be checked at an autho-
rized dealer.

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

o Fading - As your car moves away from the
radio station, the signal will weaken and
sound will begin to fade. When this occurs,
we suggest that you select another stronger
station.
o Flutter/Static - Weak FM signals or large
obstructions between the transmitter and
your radio can disturb the signal causing
static or fluttering noises to occur. Reducing
the treble level may lessen this effect until the
disturbance clears.o Station Swapping - As an FM signal weak-
ens, another more powerful signal near the
same frequency may begin to play. This is
because your radio is designed to lock onto
the clearest signal. If this occurs, select
another station with a stronger signal.
o Multi-Path Cancellation - Radio signals being
received from several directions can cause
distortion or fluttering. This can be caused by
a direct and reflected signal from the same
station, or by signals from two stations with
close frequencies. If this occurs, select
another station until the condition has passed.
B750B04Y-AATUsing a cellular phone or a two-way radioWhen a cellular phone is used inside the vehicle,
noise may be produced from the audio equip-
ment. This does not mean that something is
wrong with the audio equipment. In such a case,
use the cellular phone at a place as far as
possible from the audio equipment.
WARNING:
Don't use a cellular phone when you are
driving. This could result in loss of control,
and an accident that may cause death,
serious injury, or property damage. You
must stop at a safe place to use a cellular
phone.
