Control Switches

●

When the mode is set to

with the fan control dial in a posi-

tion other than 0 and the temperature control dial in the maximum cold posi-
tion, the air intake selector switches to the recirculated air position and the
A/C turns on automatically. If A/C is not desired, press the A/C switch to turn
it off.

●

The mode selector dial can be set at the intermediate positions (

)

between each mode. Set the dial to an intermediate position if you want to
split the airflow between the two modes.

●

For example, when the mode selector dial is at the

position between

the

and

positions, airflow from the floor vent is less than that of

the

position.

●

The air conditioner may not function when the outside temperature
approaches 32 °F (0 °C).

WARNING

■

Do not use the recirculated air position in cold or rainy weather:
Using the recirculated air position in cold or rainy weather is dangerous as it

The antenna is embedded into the window glass.

Embedded Type (if equipped)

NOTICE

When washing the inside of the window which has an antenna, use a soft
cloth dampened in lukewarm water, gently wiping the antenna lines. Use of
glass cleaning products could damage the antenna.

●

To prevent damage to the antenna, remove it before entering a car wash
facility or passing beneath a low overhead clearance.

●

Be careful around the antenna when removing snow from the roof. Other-
wise the antenna could be damaged.

Operating Tips for Audio System

Do not spill any liquid on the audio
system.

Do not insert any objects, other
than CDs, into the slot.

●

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.

●

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.

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.

NOTICE

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.

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.

Ionosphere

Station 2

Station 1

■

FM characteristics

An FM broadcast range is usually about 25 - 30 miles (40 - 50 km)
from the source. Because of extra coding needed to break the
sound into two channels, stereo FM has even less range than mon-
aural (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.

Obstruction

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.

Direct

Reflected wave

● Flutter/Skip noise

Signals from an FM transmit-
ter move in straight lines and
become weak in valleys
between tall buildings, moun-
tains, 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 charac-
terized by sound breakup.

● Strong signal noise

This occurs very close to a
transmitter tower. The broad-
cast 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 broad-
casting at similar frequencies, the original station may be tempo-
rarily lost and the second station picked up. At this time there will
be some noise from this disturbance.

Station 1
88.1 MHz

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.

● Do not use deformed or

cracked CDs. The disc may
not eject resulting in a mal-
function.

● Do not use non-conventional

discs such as heart-shaped,
octagonal discs, etc.
The disc may not eject result-
ing in a malfunction.

● If the memory portion of the

CD is transparent or translu-
cent, do not use the disc.

Transparent

-------------------------------------------------------------------------------------------------------------------------------------------------------------

iA_OM_OM99M17z_(U)

251

● 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.

● When driving over uneven

surfaces, the sound may

jump.

● CDs bearing the logo shown

in the illustration can be

played. No other discs can

be played.

● Use discs that have been legitimately produced. If illegally-cop-

ied discs such as pirated discs are used, the system may not

operate properly.

-------------------------------------------------------------------------------------------------------------------------------------------------------------

252

iA_OM_OM99M17z_(U)

● 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.

● 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.

● Dust, finger smudges, and dirt can decrease the amount of light

reflected 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.

● 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. Any-
thing that can damage, warp, or fog plastic should never be used
to clean CDs.

● The CD player ejects the CD if the CD is inserted upside down.

Also dirty and/ or defective CDs may be ejected.

● Do not insert cleaning discs in the CD player.
● Do not insert any disc with a peel-off seal affixed to it.
● This unit may not be able to play certain CD-R/CD-RWs made

using a computer or music CD recorder due to disc characteris-
tics, scratches, smudges, dirt, etc., or due to dust or condensa-
tion on the lens inside the unit.

● Storing CDs in the vehicle exposed to direct sunlight or high tem-

perature may damage the CD-R/CD-RWs, and make them
unplayable.

● CD-R/CD-RW exceeding 700 MB cannot be played.
