qOperation  
l
The engine may not start and the security  
indicator light may illuminate or flash if the  
advanced 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 box. Move the advanced key to  
another place, switch the ignition off, and  
then restart the engine.  
Arming  
The system is armed when the ignition is  
switched from ON to ACC or off. The  
security indicator light in the instrument  
cluster flashes every 2 seconds until the  
system is disarmed.  
l
Signals from a TVor radio station, or from  
a transceiver or a mobile telephone could  
interfere with your immobilizer system. If  
you are using the proper advanced key and  
the engine fails to start, check the security  
indicator light. If the indicator light is  
flashing, switch the ignition to ACC or off  
and wait for a while, then restart the  
engine. If it does not start after 3 or more  
tries, contact an Authorized Mazda Dealer.  
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.  
Since the electronic codes are reset when  
repairing the immobilizer system, the  
advanced key (including auxiliary key) are  
needed. Bring all the advanced keys  
(including auxiliary keys) to an Authorized  
Mazda Dealer.  
Disarming  
The system is disarmed when the ignition  
is switched to ON with the registered  
advanced key.  
The security indicator light illuminates for  
about 3 seconds and goes out.  
l
If the engine does not start with the  
correct advanced key, and the security  
indicator light keeps illuminating or  
flashing, the system may have a  
malfunction. Consult an Authorized  
Mazda Dealer.
