Air-Conditioning System

Operating Tips

Operate the air-conditioning system with

the engine running.

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.

(With i-stop)

The air

À ow amount may decrease

slightly while the i-stop function is
operating.

Clear all obstructions such as leaves,

snow and ice from the bonnet and the
air inlet in the cowl grille to improve the
system ef

¿ ciency.

Use the air-conditioning system to defog

the windows and dehumidify the air.

The recirculate mode should be used

when driving through tunnels or while in
a traf

¿ c jam, or when you would like to

shut off outside air for quick cooling of
the interior.

Use the outside air position for

ventilation or windscreen defrosting.

If the vehicle has been parked in direct

sunlight during hot weather, open the
windows to let warm air escape, then
run the air-conditioning system.

Run the air conditioner about 10 minutes

at least once a month to keep internal
parts lubricated.

Have the air conditioner checked before

the weather gets hot. Lack of refrigerant
may make the air conditioner less
ef

¿ cient.

The refrigerant speci

¿ cations are

indicated on a label attached to the
inside of the engine compartment. Check
the label before re

¿ lling the refrigerant.

If the wrong type of refrigerant is used,
it could result in a serious malfunction
of the air conditioner.

For details, consult an expert repairer,

we recommend an Authorised Mazda
Repairer.

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.

/:A

5–15

Interior Features

Audio System

NOTE

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.

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)

/:A

5–16

Interior Features

Audio System

Signals from an FM transmitter are similar
to beams of light because they do not
bend around corners, but they do re

À 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.

Multipath noise

Since FM signals can be re

À ected by

obstructions, it is possible to receive both
the direct signal and the re

À 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 characterised by sound breakup.

/:A

5–17

Interior Features

Audio System

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.

Do not use deformed or cracked CDs.

The disc may not eject resulting in a
malfunction.

Do not use non-conventional discs such

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