Modification and Add-OnEquipment
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 syste m 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.

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 fla shes 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 d oes 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 electronic 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.

This is the normal running position after
the engine is started. The indicator light
(amber) turns off. (The indicator light

Starting the Engine
WA R N I N G
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.
