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.
2.3-liter engine
Fuel Octane Rating*(Anti-knock index)
Premium unleaded fuel 91 [ (R
M)/2 method] (96 RON) recommended
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
This vehicle is designed to use 91 [ (RM)/2 method] (96RON) or higher gasoline for
best performance. If 91 [ (R
M)/2 method] (96RON) is not available, 87[ (RM)/2
method] (91RON) gasoline can be used. Use of gasoline lower than 91 [ (R
M)/2
method] (96RON) can decrease performance, deteriorate shift quality and cause engine
knocking during its use.
2.5-liter engine
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
ØUSE 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.
ØYour 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.
ØNever 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 Mazda warranty.
lGasohol containing more than 10 % ethanol.

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
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.
ØUSE ONLY UNLEADED FUEL.
ØDo not drive your Mazda with any sign of engine malfunction.
ØDo not coast with the ignition switched off.
ØDo not descend steep grades in gear with the ignition switched off.
ØDo not operate the engine at high idle for more than 2 minutes.
ØDo not tamper with the emission control system. All inspections and adjustments
must be made by a qualified technician.
ØDo 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.
NOTE
While the engine is off, the sound of a valve opening and closing can be heard at the middle rear of
the vehicle, however this does not indicate an abnormality. Your vehicle has a self-checking device
and it operates while the engine is off.

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 your 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 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.
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.

Break-In Period
No special break-in is necessary, but a few
precautions in the first 1,000 km (600
miles) may add to the performance,
economy, and life of your Mazda.
lDo not race the engine.lDo not maintain one constant speed,
either slow or fast, for a long period of
time.
lDo not drive constantly at full-throttle
or high engine rpm for extended
periods of time.
lAvoid unnecessary hard stops.lAvoid full-throttle starts.lDo not tow a trailer.
Money-Saving Suggestions
How you operate your Mazda determines
how far it will travel on a tank of fuel. Use
these suggestions to help save money on
fuel and repairs.
lAvoid long warm-ups. Once the engine
runs smoothly, begin driving.
lAvoid fast starts.lKeep the engine tuned. Follow the
maintenance schedule (page 8-3) and
have an Authorized Mazda Dealer
perform inspections and servicing.
lUse the air conditioner only when
necessary.
lSlow down on rough roads.lKeep the tires properly inflated.lDo not carry unnecessary weight.lDo not rest your foot on the brake
pedal while driving.
lKeep the wheels in correct alignment.lKeep windows closed at high speeds.lSlow down when driving in crosswinds
and headwinds.
WARNING
Never stop the engine when going
down a hill:
Stopping the engine when going
down a hill is dangerous. This causes
the loss of power steering and power
brake control, and may cause
damage to the drivetrain. Any loss of
steering or braking control could
cause an accident.

Floor Mat
WARNING
Make sure the floor mats are hooked
on the retention pins to prevent them
from bunching up under the foot
pedals:
Using a floor mat that is not secured
is dangerous as it will interfere with
the accelerator and brake pedal
operation, which could result in an
accident.
Do not install two floor mats, one on
top of the other, on the driver's side:
Installing two floor mats, one on top
of the other, on the driver's side is
dangerous as the retention pins can
only keep one floor mat from sliding
forward.
In using a heavy duty floor mat for
winter use always remove the
original floor mat.
Loose floor mat(s) will interfere with
the foot pedal and could result in an
accident.
When setting a floor mat, position the
floor mat so that its eyelets are inserted
over the pointed end of the retention
posts.
Rocking the Vehicle
WARNING
Do not spin the wheels at more than 56
km/h (35 mph), and do not allow
anyone to stand behind a wheel when
pushing the vehicle:
When the vehicle is stuck, spinning
the wheels at high speed is
dangerous. The spinning tire could
overheat and explode. This could
cause serious injuries.
CAUTION
Too much rocking may cause engine
overheating, transaxle failure, and
tire damage.
If you must rock the vehicle to free it from
snow, sand or mud, depress the
accelerator slightly and slowly move the
shift lever from D to R.
