WARNING
Fuel-Filler Lid and Cap
Fuel Spray:
Fuel spray is dangerous. Fuel can
burn skin and eyes and cause illness
when ingested. Fuel spray is released
when there is pressure in the fuel
tank and the fuel cap is removed too
quickly. When removing the fuel cap,
loosen the cap slightly and wait for
any hissing to stop. Then remove it.
Fuel Vapor:
Fuel vapor is dangerous. It could be
ignited by sparks or flames causing
serious burns and injuries. Before
refueling, stop the engine, and always
keep sparks and flames away from the
filler neck. Additionally, use of the
incorrect fuel filler cap or not using a
fuel filler cap may result in fuel leak,
which could result in serious burns or
death in an accident.
Always use only a genuine Mazda fuel
cap or an approved equivalent,
available at Authorized Mazda
Dealers. The wrong cap can result in a
serious malfunction of the fuel and
emission control systems. It may also
cause the check engine light in the
instrument cluster to illuminate.

Security System
Form No. 8S18-EA-03I

Maintenance
If you have a problem with the
immobilizer system or the key, consult an
Authorized Mazda Dealer.

Modification and Add-On
Equipment
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.
NOTE
• If the security indicator light comes
on and stays on when the ignition
switch is turned to the ON position,
the engine will not start.
• Signals 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.
• If the security indicator light flashes
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 while the light is flashing
you won ’t be able to restart it.
• Since the electronic codes are reset
when repairing the immobilizer
system, the keys are needed. Bring
all the existing keys to the
Authorized Mazda Dealer.
NOTE
•The 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.
• Always keep a spare key, in case
one is lost. If a key is lost, contact
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.
To avoid damage to your vehicle, do
not modify the system or install any
add-on equipment to it.
