Press the "OFF" button to stop the operation of
the heating and cooling system.
Recirculation mode :
Air from within 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 winds-hield and side windows
and the air within the passenger com-
partment will become stale. In addition,
prolonged use of the air conditioning
with the recirculation mode ( ) selec-
ted may result in the air within the pas-
senger compartment becoming exces-
sively dry.o When the ignition switch is turned "ON"
the air intake control will change to ( )
mode except for turning "OFF" the igni-
tion switch in A.Q.S mode ( ). It is
normal operation. The air intake control
is operated in "AUTO" mode when turn-
ing the ignition to the "ON" position if
the "AUTO" mode was used before shut-
ting off the engine.

position.
CAUTION:If the windows fog up with the Recircula-
tion or A.Q.S mode selected, set the air
intake control to the Fresh air position or

if the ambient temperature drops below 38.3°F.The air filter is located in front of the blower unit
behind the glove box.
It operates to decrease pollutants from entering
the car and to filter the air.

CAUTION:o Replace the filter every 12,000 miles
(20,000 km) or once a year. If the car is
being driven in severe conditions such
as dusty, rough roads, more frequent air
filter inspections and changes are re-
quired.
o When the air flow rate is decreased, it
must be checked at an authorized dealer.
o If your vehicle is not equipped with this
filter, it can be installed by your dealer.
Check with your dealer for details.

FM reception
B750A01L
Obstructed areaIron bridges
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: 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.
B750A02A-AAT
How Car Audio Works
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.Ionosphere

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. 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.
B750B02Y-AAT
Using a cellular phone or a two-way radio
When 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.
CAUTION:When using a communication system such
a cellular phone or a radio set inside the
vehicle, a separate external antenna must
be fitted. When a cellular phone or a radio
set is used with an internal antenna alone,
it may interfere with the vehicle's electrical
system and adversely affect safe operation
of the vehicle.
WARNING:Don't use a cellular phone when you are
driving. Stop at a safe place to use a cellular
phone.
