Maintenance
If you have a problem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.

Modification and Add-On
Equipment
Mazda cannot guarantee the immobilizer
system’s operation if the system has been
modified or if any add-on equipment has
been installed to it.
NOTE
•If the warning light comes on and
stays on when the ignition switch is
turned to the ON position, the
engine will not start.
•Signals from a TV or radio station,
or from a transceiver or a mobile
telephone, could interfere with your
immobilizer system. If you are
using the proper key and your
engine fails to start, check the
warning light. If it is flashing,
remove the ignition key and wait 2
seconds or more, then reinsert it and
try starting the engine again. If it
doesn’t start after 3 or more tries,
contact an Authorized Mazda
Dealer.
•If the warning light flashes

The tire pressure monitoring system
(TPMS) monitors the pressure for each
tire.
If tire pressure is too low or too high in
one or more tires, the system will inform
the driver via the warning light in the
instrument panel and by the warning beep
sound.
The tire pressure sensors installed on each
wheel send tire pressure data by radio
signal to the receiver unit in the vehicle.
TPMS does not alleviate your need to
check the pressure and condition of all
four tires before you drive each day.
Tire Pressure Monitoring
System*
Tire pressure sensors
•When the tire pressure monitoring
system warning light is lit, one or
more of your tires is significantly
under-inflated. You should stop and
check your tires as soon as possible,
and inflate them to the proper
pressure as indicated on the
vehicle’s tire information placard.
Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and
may affect the vehicle’s handling
and stopping ability. Each tire,
including the spare, should be
checked monthly when cold and set
to the recommended inflation
pressure as specified in the vehicle
placard and owner’s manual.
•To avoid false readings, the system
samples for a little while before
indicating a problem. As a result it
will not instantaneously register a
rapid tire deflation or blow out.
NOTE
This device complies with part 15 of
the FCC Rules. Operation is subject to
the following two conditions: (1) This
device may not cause harmful
interference, and (2) this device must
accept any interference received,
including interference that may cause
undesired operation.

Warning light flashes
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.

System Error Activation
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
A system error activation may occur in the
following cases:
•When there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
•When a large metallic object (e.g. a
large electric household appliance or a
desk-top computer) is placed on the
right side of the rear seat, which may
block radio signals from the tire
pressure sensor to the receiver unit.
•When using the following devices in
the vehicle that may cause radio
interference with the receiver unit.
A digital device such as a personal
computer.
A current converter device such as a
DC-AC converter.
•When excess snow or ice adheres to the
vehicle, especially around the wheels.
•When the tire pressure sensor batteries
are exhausted.•When using a wheel with no tire
pressure sensor installed.
•When using tires with steel wire
reinforcement in the side walls.
•When using tire chains

Tires and Wheels
Changing tires and wheels
The following procedure allows the
TPMS to recognize a tire pressure
sensor’s unique ID signal code whenever
tires or wheels are changed, such as
changing to and from winter tires.
When having tires changed at an
Authorized Mazda Dealer
Tire pressure sensor ID signal code
registration is completed when an
Authorized Mazda Dealer changes your
vehicle’s tires.
When changing tires yourself
If you or someone else changes tires, you
or someone else can also undertake the
steps for the TPMS to complete the ID
signal code registration.
1. After tires have been changed, turn the
ignition switch to the ON position, then
turn it back to the ACC or LOCK
position.
NOTE
A tire pressure sensor is not installed
to the temporary spare tire. The
warning light will flash continuously
while the temporary spare tire is being
used.
NOTE
Each tire pressure sensor has a unique
ID signal code. The signal code must
be registered with the TPMS before it
can work. The easiest way to do it is to
have an Authorized Mazda Dealer
change your tire and complete ID
signal code registration.

Operating Tips for Audio
System
Do Not Adjust Audio 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. Always adjust the
audio while the vehicle is stopped.
For the purposes of safe driving, adjust
the audio volume to a level that allows
you to hear sounds outside of the
vehicle.
NOTE
•Do not use the audio for long
periods of time while the engine is
off. Otherwise the battery could go
dead.
•If a digital 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.

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.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.
