2005 MAZDA MODEL 6 HATCHBACK engine

Immobilizer System
The immobilizer system allows the engine
to start only with a key the system
recognizes.
If someone attempts to start the engine
with an unrecognized key, the engine will
not start, thereby helping to prevent the
theft of your vehicle.
CAUTION
lChanges or modifications not
expressly approved by the party
responsible for compliance could
void the user's authority to operate
the equipment.
lTo avoid damage to the key, do not:
lDrop the key.lGet the key wet.lExpose the key to any kind of
magnetic field.
lExpose the key to high
temperatures on places such as the
dashboard or hood, under direct
sunlight.
CAUTION
When starting the engine do not allow
the following, as the engine may not
start due to the electronic signal from
the ignition key not being transmitted
correctly.
lA key ring rests on the key grip.
lMetal parts of other keys or metal
objects touch the key grip.
lSpare keys or keys for other vehicles
equipped with an immobilizer
system touch or come near the key
grip.
lDevices for electronic purchases, or
security passage touch or come near
the key.

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.
lIf 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.
lSince the electronic codes are reset
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.
qModification 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.
CAUTION
To avoid damage to your vehicle, do
not modify the system or install any
add-on equipment to it.

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.
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
lUSE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic converter or the oxygen sensor. The lead will
accumulate on the oxygen sensor and the catalyst inside the converter. This will result
in a malfunction of the emission control system, causing poor performance.
lYour 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.
lNever add fuel system additives. Never add cleaning agents other than those specified
by Mazda. Other cleaning agents and additives may damage the system. Consult an
Authorized Mazda Dealer.
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 ”.
Vehicle damage and drivability problems resulting from the use of the following may not
be covered by the Mazda warranty.
lGasohol containing more than 10% ethanol.
lGasoline or gasohol containing methanol.
lLeaded fuel or leaded gasohol.

Before Driving Your Mazda
Fuel and Engine Exhaust Precautions

Emission Control System
Your vehicle is equipped with an emission control system (the catalytic converter is part of
this system) that enables your vehicle to comply with existing exhaust emissions
requirements.
WARNING
Parking Over Flammable Objects:
Parking over or near anything flammable, such as dry grass, is dangerous. Even with
the engine turned off, the exhaust system could ignite it because the exhaust system
gets very hot during normal use. A resulting fire could cause serious injury or death.
Never park over or near anything flammable.
CAUTION
Ignoring the following precautions could cause lead to accumulate on the catalyst inside
the converter or cause the converter to get very hot. Either condition will damage the
converter and cause poor performance.
lUSE ONLY UNLEADED FUEL.
lDon't drive your Mazda with any sign of engine malfunction.
lDon't coast with the ignition switch turned off.
lDon't descend steep grades in gear with the ignition switch turned off.
lDon't operate the engine at high idle for more than 5 minutes.
lDon't tamper with the emission control system. All inspections and adjustments must
be made by a qualified technician.
lDon't try to push-start or pull-start your vehicle.
NOTE
Under U.S. federal law, any modification to the original-equipment emission control
system before the first sale and registration of a vehicle is subject to penalties. In some
states, such modification made on a used vehicle is also subject to penalties.

NOTE
After driving some distance and turning off the engine, the sound of a valve opening and
closing can be heard at the rear of the vehicle, however this does not indicate an
abnormality. Your vehicle has a self-checking device and it operates after turning off the
engine.

Before Driving Your Mazda
Fuel and Engine Exhaust Precautions

Engine Exhaust (Carbon Monoxide)
WARNING
Carbon Monoxide:
Engine exhaust gas is dangerous. This gas contains carbon monoxide (CO), which is
colorless, odorless, and poisonous. When inhaled, it can cause loss of consciousness
and death. If you smell exhaust gas inside your vehicle, keep all windows fully open
and contact an Authorized Mazda Dealer immediately.
Exhaust Gas in Enclosed Area:
Running the engine inside an enclosed area, such as a garage, is dangerous. Exhaust
gas, which contains poisonous carbon monoxide, could easily enter the cabin. Loss of
consciousness or even death could occur. Don't run the engine when inside an
enclosed area.
Idling with the Windows Closed:
Exhaust gas is dangerous. When your vehicle is stopped with the windows closed and
the engine running for a long time even in an open area, exhaust gas, which contains
poisonous carbon monoxide, could enter the cabin. Loss of consciousness or even
death could occur. Open the windows or adjust the heating or cooling system to draw
fresh air.
Snow Blocking the Exhaust Gas:
Running the engine when a vehicle is stopped in deep snow is dangerous. The exhaust
pipe could be blocked by the snow, allowing exhaust gas to enter the cabin. Because
exhaust gas contains poisonous carbon monoxide, anyone in the cabin could be
injured or killed. Clear the snow from underneath and around your vehicle,
particularly the tail pipe, before starting the engine.
