Operating Tips
qOperating the Climate Control
System
Operate the climate control system with
the engine running.
NOTE
To prevent the battery from being discharged,
do not leave the fan control dial on for a long
period of time with the ignition switched ON
when the engine is not running.
qClearing the Air Inlet
Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
qFoggy Windows
The windows may fog up easily in humid
weather. Use the climate control system to
defog the windows.
To help defog the windows, operate the
air conditioner to dehumidify the air.
NOTE
The air conditioner may be used along with the
heater to dehumidify the air.
qParking in Direct Sunlight
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then run
the climate control system.
qNot Using for a Long Period
Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
qCheck the Refrigerant before the
Weather Gets Hot
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient. Consult an Authorized Mazda
Dealer for refrigerant inspection.
The air conditioner is filled with
HFC134a (R134a), a refrigerant that will
not damage the ozone layer.
If the air conditioner is low on refrigerant
or has a malfunction, consult an
Authorized Mazda Dealer.

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.
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.

lThe CD player/In-dash CD changer has
been designed to play CDs bearing the
identification logo as shown below. No
other discs can be played.
lUse discs that have been legitimately
produced. If illegally-copied discs such
as pirated discs are used, the system
may not operate properly.
lBe 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.
lDo 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.
lDust, 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.
lDo 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.
lInsert discs one by one. If two discs are
inserted at the same time, the system
may not operate properly.
lThe CD player/In-dash CD changer
ejects the CD if the CD is inserted
upside down. Also dirty and/or
defective CDs may be ejected.
lDo not insert cleaning discs in the CD
player/In-dash CD changer.
lDo not insert any disc with a peel-off
seal affixed to it.
lThis 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.
lStoring CDs in the vehicle exposed to
direct sunlight or high temperature may
damage the CD-R/CD-RWs, and make
them unplayable.
lCD-R/CD-RW exceeding 700 MB
cannot be played.
lThis 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.)
lIt 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.
lThe period from when a CD-RW is
inserted to when it begins playing is
longer than a normal CD or CD-R.
