Fuel and Engine Exhaust Precautions
▼Fuel Requirements
Vehicles with catalytic converters or oxygen sensors must use O
NLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.

This vehicle will perform best w ith 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 gaso
line station pumps.
Fuel with a rating lower than 87 octane (91 RON) will negativel y affect the emission control
system performance and could also cause engine knocking and ser ious engine damage.
CAUTION
USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to th e 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 wh en 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 th e emission control system could be damaged.
Consult an Authorized Mazda Dealer for details.
Gasoline blended with oxygenates such as alcohol or ether compo unds 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 conta ining 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 mo re 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 e xhaust emissions
requirements.
WA R N I N G
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 co uld 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 sy stem. All inspections and adjustments must be
made by a qualified technician.
 Do not push-start or pull-start this 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 oper ates while the engine is off.

▼Engine Exhaust (Carbon monoxide)
WA R N I N G
Do not drive your vehicle if you smell exhaust gas inside the vehicle:
Engine exhaust gas is dangerous. This gas cont
ains 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 a ll 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-Filler Lid and Cap
WA R N I N G
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
(U.S.A. and Canada)
Always use only a genuine Mazda fuel-filler
cap or an approved eq uivalent, 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 re
mote fuel-filler lid
release.
To close, press the fuel-filler lid until it
locks securely.

▼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.

Close
CAUTION
(U.S.A. and Canada)
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.

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 the vehicle.
Do not race the engine.
Do not maintain one constant speed,
either slow or fast, for a long period of
time.
Do not drive constantly at full-throttle or
high engine rpm for extended periods of
time.
Avoid unnecessary hard stops.
Avoid full-throttle starts.
Saving Fuel and Protection of the Environment
How you operate your Mazda determines
how far it will travel on a tank of fuel. Use
these suggestions to help save fuel and
reduce CO
2.
Avoid long warm-ups. Once the engine
runs smoothly, begin driving.
Avoid fast starts.
Drive at lower speeds.
Anticipate when to apply the brakes
(avoid sudden braking).
Follow the maintenance schedule (page
6-4) and have an Authorized Mazda
Dealer perform inspections and
servicing.
Use the air conditioner only when
necessary.
Slow down on rough roads.
Keep the tires properly inflated.
Do not carry unnecessary weight.
Do not rest your foot on the brake pedal
while driving.
Keep the wheels in correct alignment.
Keep windows closed at high speeds.
Slow down when driving in crosswinds
and headwinds.
WA R N I N G
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.
