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.

To achieve maximum engine performance, use the specified fuel.
Fuel
Octane Rating*1 (Anti-knock index)
Premium unleaded fuel 91 [(R+M)/2 method] or above (96 RON or above)
Regular unleaded fuel with an octane rati ng from 87 to 90 (91 to 95 RON) can be
used, but this will reduce performance slightly, such as reduced engine output, and
engine knocking.
Fuel with a rating lower than 87 octane (91 RON) will negatively affect the emission
control system performance and could al so cause engine knocking and serious
engine damage.
*1 U.S. federal law requires that octane ratings be posted on gas station pumps.
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 cont ains any methanol. Stop using gasohol of
any kind if your vehicle engine is performing poorly.
 Never add fuel system additives other than a Mazda genuine product, 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 comm on 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.

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.
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.

Warnings and Cautionsfor Using the Emission Control System
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 dama
ge the converter
and cause poor performance.
 USE ONLY UNLEADED FUEL.
 Do not drive your Mazda with any
sign of engine malfunction.
 Do not coast if the vehicle power is
switched OFF.
 Do not descend steep grades in gear
if the vehicle power is 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 this
vehicle.
Warnings and Cautions
for 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.

How to Use the Towing
NOTE
The three main causes of vehicle-trailer accidents are driver error, excessive speed,
and improper trailer loading.
Trailer towing causes higher fuel consumption.The extra weight of the trailer may strain the engine on hot days and on long or
steep upgrades. If the temperature gauge indicates overheating, turn off the air
conditioner, drive safely to the side of the road, park off the right-of-way and wait
for engine to cool.
Verify that your Mazda maintains a near-normal attitude when a loaded or
unloaded trailer is connected. Do not drive if it has an abnormal front-up or
front-down position. Inspect for incorrec t tongue load, worn suspension parts,
and trailer overloading.
Make sure the trailer is properly loaded and the cargo is secure to prevent it from
shifting.
Make sure the mirrors conform to all govern ment regulations. If they do not, install
required rear view mirrors appropriate for towing purposes.
