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 Authorised
Mazda Repairer.
Always keep a spare key in case one is
lost. If a key is lost, consult an
Authorised Mazda Repairer as soon as
possible.
If 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
the Authorised Mazda Repairer 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 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.
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 expert repairer
(we recommend an Authorised Mazda
Repairer).
NOTE
If the security indicator light flashes
continuously while you are driving, do
not shut off the engine. Go to an expert
repairer (we recommend an Authorised
Mazda Repairer), 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 expert repairer (we
recommend an Authorised Mazda
Repairer), so that they can be
programmed.
