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 min\
imum.
This vehicle will perform best with fuel listed in the table.
FuelOctane Rating* (Anti-knock index)
Premium unleaded fuel91 [(RM)/2 method] or above (96 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline stat\
ion pumps.
You may use a regular unleaded fuel with an Octane Rating from 87 to 90 (91 to 95 RON)
but this will slightly reduce performance, such as reduced engine output\
, and engine
knocking.
CAUTION
 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. 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. 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.
 Gasohol containing more than 10 % ethanol. Gasoline or gasohol containing methanol. Leaded fuel or leaded gasohol.

Before Driving
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 e\
xhaust emissions
requirements.
WARNING
Never park over or near anything flammable:
Parking over or near anything flammable, 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 flammable. A resulting fire 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.
 USE ONLY UNLEADED FUEL. Do not drive your Mazda with any sign of engine malfunction. Do not coast with the ignition switched off. Do not descend steep grades in gear with the ignition switched off. Do not operate the engine at high idle for more than 2 minutes. Do not tamper with the emission control system. All inspections and adjustments
must be made by a qualified technician. Do not 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. 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.

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-filler 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-filler cap is removed too
quickly.
Before refueling, stop the engine, and
always keep sparks and flames away
from the filler neck:
Fuel vapor is dangerous. It could be
ignited by sparks or flames causing
serious burns and injuries.
Additionally, use of the incorrect fuel-
filler cap or not using a fuel-filler 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
overfilling the fuel tank may cause
fuel overflow or leakage. Fuel overflow
and leakage could damage the vehicle
and if the fuel ignites it could cause a
fire and explosion resulting in serious
injury or death.
CAUTION
Always use only a genuine Mazda fuel-
filler 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
When the fuel-filler lid end is pressed with
the doors unlocked, the fuel-filler lid rises.
The fuel-filler lid operates in conjunction
with the door locking/unlocking
mechanism.
Make sure to lock both the doors when
leaving the vehicle.
Refer to Door Locks on page 3-10.
To close, press the fuel-filler lid until a
click sound is heard.
NOTE
Lock the doors after closing the fuel lid.
If the fuel lid is closed after locking the
doors, the fuel lid cannot be locked.

Fuel-Filler Cap
To remove the fuel-filler cap, turn it
counterclockwise.
Attach the removed cap to the inner side
of the fuel lid.
To close the fuel-filler cap, turn it
clockwise until a click is heard.
OpenClose
CAUTION
If the check fuel cap warning light
illuminates, the fuel-filler cap may not
be properly installed. If the warning
light illuminates, park your vehicle
safely off the right-of-way, remove the
fuel-filler 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.
