KeysWARNINGDo not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the
key is dangerous. This could result in
someone being badly injured or even
killed. Children may find these keys to
be an interesting toy to play with and
could cause the power windows or
other controls to operate, or even make
the vehicle move.
CAUTION 
Because the key (transmitter) uses
low-intensity radio waves, it may not
function correctly under the following
conditions: 
The key is carried with
communication devices such as
cellular phones. 
The key contacts or is covered by a
metal object. 
The key is near electronic devices such
as personal computers. 
Non-Mazda genuine electronic
equipment is installed in the vehicle. 
There is equipment which discharges
radio waves near the vehicle. 
The key (transmitter) may consume
battery power excessively if it receives
high-intensity radio waves. Do not place
the key near electronic devices such as
televisions or personal computers. 
To avoid damage to the key
(transmitter), DO NOT: 
Drop the key. 
Get the key wet. 
Disassemble the key. 
Expose the key to high temperatures
on places such as the dashboard or
hood, under direct sunlight. 
Expose the key to any kind of
magnetic field. 
Place heavy objects on the key. 
Put the key in an ultrasonic cleaner. 
Put any magnetized objects close to
the key.
A code number is stamped on the plate
attached to the key set; detach this plate
and store it in a safe place (not in the
vehicle) for use if you need to make a
replacement key (auxiliary key).
Also write down the code number and
keep it in a separate safe and convenient
place, but not in the vehicle.
If your key (auxiliary key) is lost, consult
your Authorized Mazda Dealer and have
your code number ready.

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.

3 –48 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.
OperationNOTE 
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. 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 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.
