A/C switch
Push the switch to turn the air conditioner
on. The indicator light on the switch will
illuminate when the fan control dial is on.
Push the switch once again to turn the air
conditioner off.Air intake selector
This lever controls the source of air
entering the vehicle.
It is recommended that under normal
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.
NOTE
The air conditioner may not function
when the outside temperature
approaches 0
°C ( (32 ° F).
The Recirculated Air Position:
Using the position in cold or
rainy weather will cause the glass 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.

Audio System

Power Antenna
The antenna automatically rises when the
radio is turned on, and lowers when it is
turned off.
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.
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.
Antenna
• To prevent damaging the antenna,
retract it before entering a car wash
facility or passing beneath a low
overhead clearance.
• Make sure no one is near the
antenna before turning on the radio
to prevent injury or damage to the
antenna.

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.
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.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.
Operating Tips for Cassette Tape
Player
Cleaning the cassette tape player
The tape head, capstans, and pinch rollers
will gather oxide residue from cassette
tapes. This can cause weak or wavering
sounds and damage to the cassette tapes
and player. Use a good quality head-
cleaning tape or a liquid cleaner cassette
tape to remove it.
Should the unit not operate normally,
consult an Authorized Mazda Dealer.
Never attempt to repair it or insert a
screwdriver or anything else.
Handling the cassette tape player
The following precautions should be
observed.
• Do not spill any liquid on the audio
system.
• Do not insert any objects, other than
cassette tape, into the slot.
