Black plate (135,1)
qOperation
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.
Disarming
The system is disarmed when the ignition
is switched ON with the registered
advanced key.
The security indicator light illuminates for
about 3 seconds and goes out.
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. NOTE
lThe 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.
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 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
switch the ignition 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.
lIf 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.
lSince 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.

Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.
MZR 2.3 DISI Turbo
Your Mazda will perform best with fuel listed in the table.
FuelOctane Rating*(Anti-knock index)
Premium unleaded fuel 91 [ (R
M)/2 method] or above (96 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
This vehicle is designed for and requires use of premium unleaded fuel. If 91 octane fuel [
(R
M)/2 method] (96RON) is not available, gasoline as low as 87 octane [ (RM)/2
method] (91RON) can be used temporarily for emergency purposes. Use of gasoline lower
than 91 octane [ (R
M)/2 method] (96RON) can decrease performance during its use.
Refueling the vehicle with the correct octane fuel a couple of times will restore vehicle
performance.
SKYACTIV-G 2.0, MZR 2.0 and MZR 2.5
Your Mazda will perform best with fuel listed in the table.
Fuel Octane Rating*(Anti-knock index)
Regular unleaded fuel 87 [ (R
M)/2 method] or above (91 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
Fuel with a rating lower than 87 octane (91 RON) could cause the emission control system
to lose effectiveness. It could also cause engine knocking and serious engine damage.
CAUTION
Ø USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter and oxygen sensors and will lead
to deterioration of the emission control system and or failures.
Ø Your vehicle can only use oxygenated fuels containing no more than 10 % ethanol
by volume. Damage to your vehicle may occur when ethanol exceeds this
recommendation, or if the gasoline contains any methanol. Stop using gasohol of
any kind if your vehicle engine is performing poorly.
Ø Never add fuel system additives. Otherwise, the emission control system could be
damaged. Consult an Authorized Mazda Dealer for details.
Gasoline blended with oxygenates such as alcohol or ether compounds are generally
referred to as oxygenated fuels. The common gasoline blend that can be used with your
vehicle is ethanol blended at no more than 10 %. Gasoline containing alcohol, such as
ethanol or methanol, may be marketed under the name “Gasohol ”.
