conditions the lever be kept in the outside
air position.
Outside air position (
)
Outside air is taken into the vehicle. Use
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.
WARNING
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.

Operating Tips for Audio
System
WARNING
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.
CAUTION
For the purposes of safe driving, adjust
the audio volume to a level that allows
you to hear sounds outside of the
vehicle.
NOTE
lDo not use the audio for long periods
of time while the engine is off.
Otherwise the battery could go dead.
lIf 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.

qRadio 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.
Station 2
Station 1 Ionosphere
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.
(25—30 miles) 40—50 km FM Station
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.
AM wave
FM wave
FM wave
100—200 km (60—120 miles) Ionosphere
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.
