this position for normal ventilation and
heating.
Recirculated air position ( )
Outside air is shut off. Air within the
vehicle is recirculated.
This position can be used when driving on
a dusty road or in similar conditions. It
also helps to provide quicker cooling of
the interior.

Heating
1. Set the mode selector dial to the
position.
2. Set the temperature control dial to the hot position.
3. Set the fan control dial to the desired speed.

Cooling (With Air Conditioner)
1. Set the mode selector dial to the
position.
2. Set the temperature control dial to the cold position.
3. Set the fan control dial to the desired speed.
4. Turn on the air conditioner.
5. Adjust the fan control dial and temperature control dial to maintain
maximum comfort.
The Recirculated Air Position:
Using the position in cold or
rainy weather will cause the windows
to fog up. Your vision will be
hampered, which could lead to a
serious accident. Do not use the
position in cold or rainy weather.
NOTE
•If the windshield fogs up easily, set
the mode selector dial to the
position.
• If cooler air is desired at face level,
set the mode selector dial at the
position and adjust the temperature
control dial to maintain maximum
comfort.
• The air to the floor is warmer than
air to the face (except when the
temperature control dial is set at the
extreme hot or cold position).
• In the position, air conditioning
is automatically turned on to defrost
the windshield (however, the
indicator light does not illuminate)
and the position is
automatically selected.
WARNING
When using the air conditioner while
driving up long hills or in heavy traffic,
closely monitor the temperature gauge
(page 5-29).
The air conditioner may cause engine
overheating. If the gauge indicates
overheating, turn the air conditioner
off.

Foggy Windshield:
Using the position with the
temperature control set to the cold
position will cause the outside of the
windshield to fog up. Your vision will
be hampered, which could lead to a
serious accident. Set the temperature
control to the hot or warm position
when using the position.
NOTE
•For maximum defrosting, set the
temperature control dial to the

Operating Tips for Audio
System
Do Not Adjust Audio While Driving
the Vehicle:
Adjusting the audio while driving the
vehicle is dangerous as it could
distract your attention from the
vehicle operation which could lead to
a serious accident. Always adjust the
audio while the vehicle is stopped.
For the purposes of safe driving, adjust
the audio volume to a level that allows
you to hear sounds outside of the
vehicle.
NOTE
•
Do not use the audio for long
periods of time while the engine is
off. Otherwise the battery could go
dead.
• If a digital cellular phone or CB
radio is used in or near the vehicle,
it could cause noise to occur from
the audio system, however, this does
not indicate that the system has
been damaged.

Radio Reception
AM characteristics
AM signals bend around such things as
buildings or mountains and bounce off the
ionosphere. Therefore, they can reach
longer distances than FM signals. Because
of this, two stations may sometimes be
picked up on the same frequency at the
same time.
FM characteristics
An FM broadcast range is usually about
40
—50 km (25 —30 miles) from the
source. Because of extra coding needed to
break the sound into two channels, stereo
FM has even less range than monaural
(non-stereo) FM. Signals from an FM transmitter are
similar to beams of light because they do
not bend around corners, but they do
reflect. Unlike AM signals, FM signals
cannot travel beyond the horizon.
Therefore, FM stations cannot be received
at the great distances possible with AM
reception.
Atmospheric conditions can also affect
FM reception. High humidity will cause
poor reception. However, cloudy days
may provide better reception than clear
days.
Multipath noise
Since FM signals can be reflected by
obstructions, it is possible to receive both
the direct signal and the reflected signal at
the same time. This causes a slight delay
in reception and may be heard as a broken
sound or a distortion. This problem may
also be encountered when in close
proximity to the transmitter.

Flutter/Skip noise
Signals from an FM transmitter move in
straight lines and become weak in valleys
between tall buildings, mountains, and
other obstacles. When a vehicle passes
through such an area, the reception
conditions may change suddenly,
resulting in annoying noise.
Weak signal noise
In suburban areas, broadcast signals
become weak because of distance from
the transmitter. Reception in such fringe
areas is characterized by sound breakup.Strong signal noise
This occurs very close to a transmitter
tower. The broadcast signals are
extremely strong, so the result is noise and
sound breakup at the radio receiver.
Station drift noise
When a vehicle reaches the area of two
strong stations broadcasting at similar
frequencies, the original station may be
temporarily lost and the second station
picked up. At this time there will be some
noise from this disturbance.
Station 1
88.1 MHz
Station 2
88.3 MHz
