Fuel and Emission
Fuel and Engine Exhaust Precautions
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.

This vehicle 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) will negatively affect the emission control
system performance and could also cause engine knocking and serious engine damage.
CAUTION




¾ 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.
 


¾ This vehicle can only use oxygenated fuels containing no more than 10 % ethanol by
volume. Damage to the 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.
 


¾ 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".

Vehicle damage and drivability problems resulting from the use of the following may not be
covered by the warranty.
 


y Gasohol containing more than 10 % ethanol.



y Gasoline or gasohol containing methanol.



y Leaded fuel or leaded gasohol.

Fuel and Emission
Emission Control System
This vehicle is equipped with an emission control system (the catalytic converter is
part of this system) that enables the vehicle to comply with existing exhaust emissions
requirements.
WARNING
Never park over or near anything fl ammable:
Parking over or near anything fl ammable, such as dry grass, is dangerous. Even with the
engine turned off , the exhaust system remains very hot after normal use and could ignite
anything fl ammable. A resulting fi re could cause serious injury or death.

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.
 


¾ USE ONLY UNLEADED FUEL.



¾ Do not drive your Mazda with any sign of engine malfunction.



¾ Do not coast with the ignition switched off .



¾ Do not descend steep grades in gear with the ignition switched off .



¾ Do not operate the engine at high idle for more than 2 minutes.



¾ Do not tamper with the emission control system. All inspections and adjustments
must be made by a qualifi ed technician.
 


¾ Do not push-start or pull-start your vehicle.
N O T E




y Under U.S. federal law, any modi¿ cation to the original-equipment emission control
system before the ¿ rst sale and registration of a vehicle is subject to penalties. In some
states, such modi¿ cation made on a used vehicle is also subject to penalties.




y While the engine is off, the sound of a valve opening and closing can be heard at the rear
of the vehicle, however this does not indicate an abnormality. The vehicle has a self-
checking device and it operates while the engine is off.

Before Driving
Fuel and Emission
Engine Exhaust (Carbon monoxide)
WARNING
Do not drive your vehicle if you smell exhaust gas inside the vehicle:
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 the vehicle, keep all windows fully open and contact
an Authorized Mazda Dealer immediately.

Do not run the engine when inside an 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.

Open the windows or adjust the heating or cooling system to draw fresh air when
idling the engine:
Exhaust gas is dangerous. When the 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.

Clear snow from underneath and around your vehicle, particularly the tail pipe, before
starting the engine:
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, it could cause loss of consciousness or
even death to occupants in the cabin.

Fuel and Emission
Fuel-Filler Lid and Cap
WARNING
When removing the fuel-fi ller cap,
loosen the cap slightly and wait for any
hissing to stop, then remove it:
Fuel spray is dangerous. Fuel can
burn skin and eyes and cause illness
if ingested. Fuel spray is released
when there is pressure in the fuel tank
and the fuel-fi ller cap is removed too
quickly.

Before refueling, stop the engine, and
always keep sparks and fl ames away
from the fi ller neck:
Fuel vapor is dangerous. It could be
ignited by sparks or fl ames causing
serious burns and injuries.
Additionally, use of the incorrect fuel-
fi ller cap or not using a fuel-fi ller cap
may result in a fuel leak, which could
result in serious burns or death in an
accident.

Do not continue refueling after the fuel
pump nozzle shuts off automatically:
Continuing to add fuel after the
fuel pump nozzle has shut off
automatically is dangerous because
overfi lling the fuel tank may cause
fuel overfl ow or leakage. Fuel overfl ow
and leakage could damage the vehicle
and if the fuel ignites it could cause a
fi re and explosion resulting in serious
injury or death.

CAUTION
Always use only a genuine Mazda fuel-
fi ller cap or an approved equivalent,
available at an Authorized Mazda
Dealer. 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.

Fuel-Filler Lid
To open, pull the remote fuel-¿ ller lid
release.
To close, press the fuel-¿ ller lid until it
locks securely.

CAUTION
If the check fuel cap warning light
illuminates, the fuel-fi ller cap may not
be properly installed. If the warning
light illuminates, park your vehicle
safely off the right-of-way, remove the
fuel-fi ller cap and reinstall it correctly.
After the cap has been correctly
installed, the fuel cap warning light
may continue to illuminate until a
number of driving cycles have been
completed. A drive cycle consists of
starting the engine (after four or more
hours with the engine off ) and driving
the vehicle on city and highway roads.
Continuing to drive with the check
fuel cap warning light illuminated
could cause the check engine light to
illuminate as well.

Windows
The power window auto function will only
resume on a power window that has been
reset.

1. Switch the ignition ON.
2. Make sure that the power window lock
switch located on the driver's door is
not depressed.
3. Press the switch and fully open the
window.
4. Pull up the switch to fully close the
window and continue holding the
switch for about 2 seconds after the

Jam-safe window
If a person's hands, head or an object
blocks the window during the auto-closing
operation, the window will stop and open
halfway.
WARNING
Make sure nothing blocks the window
just before it reaches the fully closed
position or while holding up the power
window switch:
Blocking the power window just before
it reaches the fully closed position or
while holding up the power window
switch is dangerous.
In this case, the jam-safe function
cannot prevent the window from
closing all the way. If fi ngers are
caught, serious injuries could occur.

N O T E
 


y Depending on driving conditions, a
closing power window could stop and
start opening when the window feels
a shock that is similar to something
blocking it.
  In the event the jam-safe function
activates and the power window cannot
be closed automatically, pull and hold
the switch and the window will close.
 


y The jam-safe window function does not
operate until the system has been reset.

Engine-off power window operation
The power window can be operated for
about 40 seconds after the ignition is
switched from ON to off with all doors
closed. If any door is opened, the power
window will stop operating.
N O T E
For engine-off operation of the power
window, the switch must be held up ¿ rmly
throughout window closure because the
auto-closing function will be inoperable.

Security System
N O T E
 


y The keys carry a unique electronic code.
For this reason, and to assure your
safety, obtaining a replacement key
requires some waiting time. They are
only available through an Authorized
Mazda Dealer.
 


y Always keep a spare key in case one
is lost. If a key is lost, consult an
Authorized Mazda Dealer as soon as
possible.
 


y 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
an Authorized Mazda Dealer to reset.
  Starting the vehicle with a key that has
not been reset is not possible.

Operation
N O T E
 


y The engine may not start and security
indicator light may illuminate or À ash
if the key is placed in an area where it
is dif¿ cult for the system to detect the
signal, such as on the dashboard or in
the glove compartment. Move the key
to a location within the signal range,
switch the ignition off, and then restart
the engine.
 


y Signals from a TV or radio station, or
from a transceiver or mobile telephone
could interfere with your immobilizer
system. If you are using the proper key
and the engine fails to start, check the
security indicator light.

Arming
The system is armed when the ignition is
switched from ON to off.
The security indicator light in the
instrument cluster À ashes every 2 seconds
until the system is disarmed.



Disarming
The system is disarmed when the
ignition is switched ON with the correct
programmed key. The security indicator
light illuminates for about 3 seconds and
then turns off. If the engine does not start
with the correct key, and the security
indicator light remains illuminated or
À ashing, try the following:
Make sure the key is within the
operational range for signal transmission.
Switch the ignition off, and then restart the
engine. If the engine does not start after
3 or more tries, contact an Authorized
Mazda Dealer.
N O T E
 


y If the security indicator light À ashes
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 À ashing, you will
not be able to restart it.
 


y Because the electronic codes are
reset when the immobilizer system
is repaired, the keys are needed.
Make sure to bring all the keys to an
Authorized Mazda Dealer so that they
can be programmed.
