Climate Control System
Windshield Defrosting and Defogging
Press the windshield defroster switch.
In this position, the outside air position
is automatically selected, and the air
conditioner automatically turns on. The
air conditioner will directly dehumidify
the air to the front windshield and side
windows (on Page 5-4 ). Airfl ow amount
will be increased.
WARNING
Set the temperature control to the hot
or warm position when defogging (

position): Using the
position with the
temperature control set to the cold
position is dangerous as it will cause
the outside of the windshield to fog up.
Your vision will be hampered, which
could lead to a serious accident.
NOTE
Use the temperature control dial to
increase the air fl ow temperature and
defog the windshield more quickly.
Sunlight/Temperature Sensor
The climate control system measures
inside and outside temperatures, and
sunlight. It then sets temperatures inside
the passenger compartment accordingly.
CAUTION
Do not obstruct either sensor,
otherwise the climate control system
will not operate properly.

Operating Tips for Audio
System
WARNING
Always adjust the audio while the
vehicle is stopped: Do not adjust the audio control
switches 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.
Even if the audio control switches are
equipped on the steering wheel, learn
to use the switches without looking
down at them so that you can keep
your maximum attention on the road
while driving the vehicle.
CAUTION
For the purposes of safe driving,
adjust the audio volume to a level that
allows you to hear sounds outside of
the vehicle including car horns and
particularly emergency vehicle sirens.
NOTE
 y To prevent the battery from being
discharged, do not leave the audio
system on for a long period of time
when the engine is not running.
 y If a 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.

Interior Features
Audio System
Do not spill any liquid on the audio
system.
Do not insert any objects, other than CDs,
into the slot.
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.
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.
FM Station
40—50km
(25—30 miles)
Signals from an FM transmitter are similar
to beams of light because they do not
bend around corners, but they do refl ect.
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.

Interior Features
Audio System
Multipath noise
Since FM signals can be refl ected by
obstructions, it is possible to receive both
the direct signal and the refl ected 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.
Reflected wave
Direct
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 2
88.3 MHz
Station 1
88.1 MHz

Operating Tips for CD Player
Condensation phenomenon
Immediately after turning on the heater
when the vehicle is cold, the CD or
optical components (prism and lens) in
the CD player may become clouded with
condensation. At this time, the CD will
eject immediately when placed in the unit.
A clouded CD can be corrected simply by
wiping it with a soft cloth. Clouded optical
components will clear naturally in about
an hour. Wait for normal operation to
return before attempting to use the unit.
Handling the CD player
The following precautions should be
observed.
 y The CD revolves at high speed within
the unit. Defective (cracked or badly
bent) CDs should never be used.
 y  Do not use non-conventional discs such
as heart-shaped, octagonal discs, etc.
The disc may not eject resulting in a
malfunction.
 y  If the memory portion of the CD is
transparent or translucent, do not use the
disc.
Transparent
 y  A new CD may have rough edges on its
inner and outer perimeters. If a disc with
rough edges is used, proper setting will
not be possible and the CD player will
not play the CD. In addition, the disc
may not eject resulting in a malfunction.
Remove the rough edges in advance
by using a ball-point pen or pencil as
shown below. To remove the rough
edges, rub the side of the pen or pencil
against the inner and outer perimeter of
the CD.
 y  When driving over uneven surfaces, the
sound may jump.

Audio System
 y The CD player has been designed to
play CDs bearing the identifi cation logo
as shown below. No other discs can be
played.
 y  Use discs that have been legitimately
produced. If illegally-copied discs such
as pirated discs are used, the system may
not operate properly.
 y  Be sure never to touch the signal surface
when handling the CDs. Pick up a CD
by grasping the outer edge or the edge of
the hole and the outer edge.
 y  Do not stick paper or tape on the CD.
Avoid scratching the reverse side (the
side without a label). The disc may not
eject resulting in a malfunction.
 y  Dust, fi nger smudges, and dirt can
decrease the amount of light refl ected
from the signal surface, thus affecting
sound quality. If the CD should become
soiled, gently wipe it with a soft cloth
from the center of the CD to the edge.
 y  Do not use record sprays, antistatic
agents, or household spray cleaners.
Volatile chemicals such as benzine and
thinner can also damage the surface of
the CD and must not be used. Anything
that can damage, warp, or fog plastic
should never be used to clean CDs.
 y  The CD player ejects the CD if the CD
is inserted upside down. Also dirty and/
or defective CDs may be ejected.
 y  Do not insert cleaning discs in the CD
player.
 y  Do not insert any disc with a peel-off
seal affi xed to it.
 y This unit may not be able to play certain
CD-R/CD-RWs made using a computer
or music CD recorder due to disc
characteristics, scratches, smudges, dirt,
etc., or due to dust or condensation on
the lens inside the unit.
 y  Storing CDs in the vehicle exposed to
direct sunlight or high temperature may
damage the CD-R/CD-RWs, and make
them unplayable.
 y  CD-R/CD-RW exceeding 700 MB
cannot be played.
 y  This unit may not be able to play certain
discs made using a computer due to the
application (writing software) setting
used. (For details, consult the store
where the application was purchased.)
 y  It is possible that certain text data, such
as titles, recorded on a CD-R/CD-RW
may not be displayed when musical data
(CD-DA) is playing.
 y  The period from when a CD-RW is
inserted to when it begins playing is
longer than a normal CD or CD-R.
 y  Completely read the instruction manual
and cautions for CD-R/CD-RWs.
 y  Do not use discs with cellophane tape
adhering, partially peeled off labels,
or adhesive material exuding from the
edges of the CD label. Also, do not use
discs with a commercially-available
CD-R label affi xed. The disc may not
eject resulting in a malfunction.
