Modification and
Add-On Equipment
▼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
▼Immobilizer System
The immobilizer system allows the
engine to start only with a key the
system recognises.

If someone attempts to start the
engine with an unrecognised 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 expert repairer (we recommend an
Authorised Mazda Repairer).
CAUTION
¾Changes or modifications not
expressly approved by the party
responsible for compliance could
void the user's authority to operate
the equipment.
¾To avoid damage to the key, do not:
¾Drop the key.
¾Get the key wet.
¾Expose the key to any kind of
magnetic field.
¾Expose the key to high
temperatures on places such as the
instrument panel or bonnet, under
direct sunlight.
¾If 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 expert repairer (we
recommend an Authorised Mazda
Repairer).

NOTE
xThe 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
Authorised Mazda Repairer.
xAlways keep a spare key in case one
is lost. If a key is lost, consult an
Authorised Mazda Repairer as soon
as possible.
xIf you lose a key, an Authorised
Mazda Repairer will reset the
electronic codes of your remaining
keys and immobilizer system. Bring
all the remaining keys to an
Authorised Mazda Repairer to reset.
Starting the vehicle with a key that
has not been reset is not possible.
▼Operation
NOTE
xThe 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 instrument
panel or in the glove compartment.
Move the key to a location within
the signal range, switch the ignition
off, and then restart the engine.
xSignals 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 expert repairer (we
recommend an Authorised Mazda
Repairer).

Theft-Deterrent System*
▼Theft-Deterrent System
If the theft-deterrent system detects an
inappropriate entry into the vehicle or
the intrusion sensor detects movement
in the vehicle which could result in the
vehicle (with the intrusion sensor) or
its contents being stolen, the alarm
alerts the surrounding area of an
abnormality by sounding the siren/
horn and flashing the hazard warning
lights.

The system will not function unless it's
properly armed. So when you leave the
vehicle, follow the arming procedure
correctly.
Intrusion sensor
*
The intrusion sensor uses ultrasonic
waves to detect movement inside the
vehicle and to raise an alert of an
intrusion into the vehicle.

The intrusion sensor detects certain
kinds of movement inside the vehicle,
however, it may also respond to
phenomenon outside the vehicle such
as vibrations, loud noise, wind, and air
currents.
CAUTION
In order for the intrusion sensor to
operate appropriately, be aware of the
following:
¾Do not hang clothing or objects from
a head restraint or a coat hook.
¾Return the extension sunvisors to
their original positions.
¾Do not blind the intrusion sensor by
covering it or placing objects over it.
¾Do not allow the intrusion sensor to
get soiled or wipe it with a liquid.
¾Do not shock or cause an impact to
the intrusion sensor or the intrusion
sensor bezel.
¾Do not install seats that are not
Mazda genuine products.
¾To prevent obstruction of intrusion
sensor, do not place objects or cargo
near the intrusion sensor that are
higher than the head restraints.

Floor Mat
▼Floor Mat
We recommend the use of Genuine
Mazda
floor mats.
WARNING
Make sure the
floor mats are secured
with the grommets or the retainers to
prevent them from bunching up
under the foot pedals (Driver's side):
Using a
floor mat that is not secured is
dangerous as it will interfere with the
accelerator and brake pedal operation
(driver's side), which could result in an
accident.
Only use a
floor mat which conforms
to the shape of the floor on the driver's
side and make sure it is oriented
correctly.
Secure the floor mat using the
grommets or retainers.
There are various ways to secure floor
mats depending on the type used,
therefore secure the mat according to
the type.
After installing the
floor mat, make
sure that it does not slide from side to
side or back and forth, and that there
is sufficient clearance with the
accelerator and brake pedals on the
driver's side.
After removing the floor mat for
cleaning or some other reason, always
securely reinstall it while paying
attention to the precautions just
mentioned.
Do not install two floor mats, one on
top of the other, on the driver's side:
Installing two floor mats, one on top of
the other, on the driver's side is
dangerous as the retention pins can
only keep one floor mat from sliding
forward.
Loose floor mat(s) will interfere with
the foot pedals and could result in an
accident.
If using an all-weather mat for winter
use always remove the original floor
mat.
When setting a
floor mat, position the
floor mat so that its grommets or
retainers are inserted over the pointed
end of the retention posts.
