When the ignition is switched to ACC or
ON, the vehicle lock-out prevention
feature prevents you from locking
yourself out of the vehicle.
Both doors and the fuel-filler lid will
automatically unlock if they are locked
using the power door locks with any
door open.
If both the doors are closed even though
the trunk lid is open, both the doors and
the fuel-filler lid will lock.
The vehicle lock-out prevention feature
does not operate while the ignition is

The horn sound is heard twice to notify
the driver that the key has been left in
the vehicle.
(Door unlock (control) system with
collision detection)
This system automatically unlocks the
doors and the fuel-filler lid in the event
the vehicle is involved in an accident to
allow passengers to get out of the
vehicle immediately and prevent being
trapped inside. While the ignition is
switched ON and in the event the vehicle
receives an impact strong enough to
inflate the air bags, both the doors and
the fuel-filler lid are automatically
unlocked after about 6 seconds have
elapsed from the time of the accident.
The doors and the fuel-filler lid may not
unlock depending on how an impact is
applied, the force of the impact, and
other conditions of the accident.

malfunctioning, the doors and the
fuel-filler lid will not unlock.
When opening a door, the power
windows open a little automatically.
When closing the door, the power
windows close automatically. This is a
function for improving the sealability,
and it does not mean there is a problem.
If the vehicle battery is disconnected for
vehicle maintenance or other reasons,
the power windows will not open or
close automatically. If the power
windows do not open or close, the
automatic open/close mechanism for the
windows must be reset.

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
the 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. 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.
