Security System
Modification and Add-On
Equipment
Mazda cannot guarantee the immobilizer
and the theft-deterrent systems' operation
if the system has been modified or if any
add-on equipment has been installed.
CAUTION
To avoid damage to the vehicle, do
not modify the system or install any
add-on equipment to the immobilizer
and the theft-deterrent systems or the
vehicle.
Immobilizer System
The immobilizer system allows the
engine to start only with a key the system
recognizes.
If someone attempts to start the engine
with an unrecognized key, the engine
will not start, thereby helping to prevent
vehicle theft.
If you have a problem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.
CAUTION
 Radio equipment like this is governed by
laws in the United States.
Changes or modifications not expressly
approved by the party responsible
for compliance could void the user's
authority to operate the equipment.
 To avoid damage to the key, do not:
 Drop the key. Get the key wet. Expose the key to any kind of
magnetic field. Expose the key to high temperatures
on places such as the dashboard or
hood, under direct sunlight.
 If the engine does not start with the
correct key, and the security indicator
light keeps illuminating or flashing, the
system may have a malfunction. Consult
an Authorized Mazda Dealer.

Before Driving
Security System
NOTE
 The keys carry a unique electronic code.
For this reason, and to assure your
safety, obtaining a replacement key
requires some waiting time. They are
only available through an Authorized
Mazda Dealer.
 Always keep a spare key in case one
is lost. If a key is lost, consult an
Authorized Mazda Dealer as soon as
possible.
 If you lose a key, an Authorized Mazda
Dealer will reset the electronic codes of
your remaining keys and immobilizer
system. Bring all the remaining keys to
an Authorized Mazda Dealer to reset.
Starting the vehicle with a key that has
not been reset is not possible.
Operation
NOTE
 The engine may not start and security
indicator light may illuminate or flash
if the key is placed in an area where it
is difficult for the system to detect the
signal, such as on the dashboard or in
the glove compartment. Move the key
to a location within the signal range,
switch the ignition off, and then restart
the engine.
 Signals from a TV or radio station, or
from a transceiver or mobile telephone
could interfere with your immobilizer
system. If you are using the proper key
and the engine fails to start, check the
security indicator light.
Arming
The system is armed when the ignition is
switched from ON to off.
The security indicator light in the
instrument cluster flashes every 2 seconds
until the system is disarmed.
Disarming
The system is disarmed when the
ignition is switched ON with the correct
programmed key. The security indicator
light illuminates for about 3 seconds and
then turns off. If the engine does not start
with the correct key, and the security
indicator light remains illuminated or
flashing, try the following:
Make sure the key is within the
operational range for signal transmission.
Switch the ignition off, and then restart the
engine. If the engine does not start after
3 or more tries, contact an Authorized
Mazda Dealer.
NOTE
 If the security indicator light flashes
continuously while you are driving,
do not shut off the engine. Go to an
Authorized Mazda Dealer and have it
checked. If the engine is shut off while
the indicator light is flashing, you will
not be able to restart it.
 Because the electr onic codes are
reset when the immobilizer system
is repaired, the keys are needed.
Make sure to bring all the keys to an
Authorized Mazda Dealer so that they
can be programmed.

When Driving
Start/Stop Engine
ON
This is the normal running position after
the engine is started. The indicator light
(amber) turns off. (The indicator light
(amber) illuminates when the ignition
is switched ON and the engine is not
running.)
Some indicator lights/warning lights
should be inspected before the engine is
started (page 4-20).
NOTE
When the push button start is pressed to
ON, the sound of the fuel pump motor
operating near the fuel tank can be heard.
This does not indicate an abnormality.
Starting the Engine
WARNING
Radio waves from the key may affect
medical devices such as pacemakers:
Before using the key near people who
use medical devices, ask the medical
device manufacturer or your physician
if radio waves from the key will affect
the device.
NOTE
 The key must be carried because the key
carries an immobilizer chip that must
communicate with the engine controls at
short range.
 The engine can be started when the
push button start is pressed from off,
ACC, or ON.
 The push button start system functions
(function which can start the engine
by only carrying the key) can be
deactivated to prevent any possible
adverse effect on a user wearing a
pacemaker or other medical device. If
the system is deactivated, you will be
unable to start the engine by carrying
the key. Consult an Authorized Mazda
Dealer for details. If the push button
start system functions have been
deactivated, you can start the engine by
following the procedure indicated when
the key battery goes dead.
Refer to Engine Start Function When
Key Battery is Dead on page 4-8.
