NOTE
lIf the security indicator light comes
on and stays on when the ignition
switch is turned to the ON position,
the engine will not start.
lSignals from a TV or radio station, or
from a transceiver or a mobile
telephone, could interfere with your
immobilizer system. If you are using
the proper key and your engine fails
to start, check the security indicator
light. If it is flashing, remove the
ignition key and wait 2 seconds or
more, then reinsert it and try starting
the engine again. If it doesn't start
after 3 or more tries, contact an
Authorized Mazda Dealer.

continuously while you are driving,
don't shut off the engine. Go to an
Authorized Mazda Dealer and have
it checked. If you shut off the engine

when repairing the immobilizer
system, the keys are needed. Bring
all the existing keys to an Authorized
Mazda Dealer.
qMaintenance
If you have a problem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.
NOTE
lThe keys carry a unique electronic
code. For this reason, and to assure
your safety, obtaining replacement
key requires some waiting time.
They are only available through an
Authorized Mazda Dealer.
lAlways keep a spare key, in case one
is lost. If a key is lost, contact an
Authorized Mazda Dealer as soon as
possible.
lIf 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.

Mazda cannot guarantee the immobilizer
system's operation if the system has been
modified or if any add-on equipment has
been installed to it.
CAUTION
To avoid damage to your vehicle, do
