Roadside Emergencies

swallowed, call a physician immediately, even if no symptoms are
immediately apparent. The toxic effects of fuel may not be visible for
hours.
²Avoid inhaling fuel vapors. Inhaling too much fuel vapor of any kind
can lead to eye and respiratory tract irritation. In severe cases,
excessive or prolonged breathing of fuel vapor can cause serious
illness and permanent injury.
²Avoid getting fuel liquid in your eyes. If fuel is splashed in the eyes,
remove contact lenses (if worn), flush with water for 15 minutes and
seek medical attention. Failure to seek proper medical attention could
lead to permanent injury.
²Fuels can also be harmful if absorbed through the skin. If fuel is
splashed on the skin and/or clothing, promptly remove contaminated
clothing and wash skin thoroughly with soap and water. Repeated or
prolonged skin contact with fuel liquid or vapor causes skin irritation.
²Be particularly careful if you are taking ªAntabuseº or other forms of
disulfiram for the treatment of alcoholism. Breathing gasoline vapors,
or skin contact could cause an adverse reaction. In sensitive
individuals, serious personal injury or sickness may result. If fuel is
splashed on the skin, promptly wash skin thoroughly with soap and
water. Consult a physician immediately if you experience an adverse
reaction.
WARNING: When refueling always shut the engine off and
never allow sparks or open flames near the filler neck. Never
smoke while refueling. Fuel vapor is extremely hazardous under
certain conditions. Care should be taken to avoid inhaling
excess fumes.
WARNING: The flow of fuel through a fuel pump nozzle can
produce static electricity, which can cause a fire if fuel is
pumped into an ungrounded fuel container.
Use the following guidelines to avoid static build-up when filling an
ungrounded fuel container:
²Place approved fuel container on the ground.
²DO NOT fill a fuel container while it is in the vehicle (including the
cargo area).

²Keep the fuel pump nozzle in contact with the fuel container while
filling.
²DO NOT use a device that would hold the fuel pump handle in the fill
position.
Fuel Filler Cap
Your fuel tank filler cap has an indexed design with a 1/8 turn on/off
feature.
When fueling your vehicle:
1. Turn the engine off.
2. Carefully turn the filler cap counterclockwise 1/8 of a turn until it
stops.
3. Pull to remove the cap from the fuel filler pipe.
4. To install the cap, align the tabs on the cap with the notches on the
filler pipe.
5. Turn the filler cap clockwise 1/8 of a turn until it stops.
ªCheck Fuel Capº illuminates when the ignition is turned to the ON
position to ensure your bulb is working. When this light turns on, check
the fuel filler cap. Continuing to operate the vehicle with the Check Fuel
Cap light on, can activate the Service Engine Soon warning. When the
fuel filler cap is properly re-installed, the light(s) will turn off after a
period of normal driving.It may take a long period of time for the
system to detect an improperly installed fuel filler cap.
If you must replace the fuel filler cap, replace it with a fuel filler
cap that is designed for your vehicle. The warranty may be void
for any damage to the fuel tank or fuel system if the correct
genuine Mazda fuel filler cap is not used.
WARNING: The fuel system may be under pressure. If the fuel
filler cap is venting vapor or if you hear a hissing sound, wait
until it stops before completely removing the fuel filler cap.
Otherwise, fuel may spray out and injure you or others.
Maintenance and Specifications
253

WARNING: If you do not use the proper fuel filler cap,
excessive pressure or vacuum in the fuel tank may damage the
fuel system or cause the fuel cap to disengage in a collision,
which may result in possible personal injury.
Choosing the right fuel
Use only UNLEADED FUEL. The use of leaded fuel is prohibited by law
and could damage your vehicle.
Do not use fuel containing methanol. It can damage critical fuel system
components.
Your vehicle was not designed to use fuel or fuel additives with metallic
compounds, including manganese-based compounds containing MMT.
Repairs to correct the effects of using a fuel for which your vehicle was
not designed may not be covered by your warranty.
Octane recommendations
Your vehicle is designed to use
ªRegularº unleaded gasoline with
pump (R+M)/2 octane rating of 87.
We do not recommend the use of
gasolines labeled as ªRegularº that
are sold with octane ratings of 86 or lower in high altitude areas.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized Mazda
dealership to prevent any engine damage.
Fuel quality
If you are experiencing starting, rough idle or hesitation driveability
problems during a cold start, try a different brand of ªRegularº unleaded
gasoline. ªPremiumº unleaded gasoline is not recommended (particularly
in the United States) because it may cause these problems to become
more pronounced. If the problems persist, see your authorized Mazda
dealership.
It should not be necessary to add any aftermarket products to your fuel
tank if you continue to use high quality fuel of the recommended octane
rating. Aftermarket products could cause damage to the fuel system.
87(R+M)/2 METHOD
Maintenance and Specifications
254

Repairs to correct the effects of using an aftermarket product in your
fuel may not be covered by your warranty.
Many of the world's automakers
issued the World-wide Fuel Charter
that recommends gasoline
specifications to provide improved
performance and emission control
system protection for your vehicle.
Gasolines that meet the World-wide
Fuel Charter should be used when
available. Ask your fuel supplier
about gasolines that meet the
World-wide Fuel Charter. In Canada,
look for fuels that display theAuto Makers' Choiceylogo.
Cleaner air
Mazda endorses the use of reformulated ªcleaner-burningº gasolines to
improve air quality.
Running out of fuel
Avoid running out of fuel because this situation may have an adverse
affect on powertrain components.
If you have run out of fuel:
²You may need to cycle the ignition from OFF to ON several times after
refueling, to allow the fuel system to pump the fuel from the tank to
the engine.
²Your ªCheck Engineº indicator may come on. For more information on
the ªCheck Engineº indicator, refer to theInstrument Cluster
chapter.
Fuel Filter
For fuel filter replacement, see your authorized Mazda dealership. Refer
to the service maintenance section for the appropriate intervals for
changing the fuel filter.
Replace the fuel filter with an authorized Mazda part. The
customer warranty may be void for any damage to the fuel system
if an authorized Mazda fuel filter is not used.

ESSENTIALS OF GOOD FUEL ECONOMY
Measuring techniques
Your best source of information about actual fuel economy is you, the
driver. You must gather information as accurately and consistently as
possible. Fuel expense, frequency of fillups or fuel gauge readings are
NOT accurate as a measure of fuel economy. We do not recommend
taking fuel economy measurements during the first 1, 600 km (1, 000
miles) of driving (engine break-in period). You will get a more accurate
measurement after 3, 000 km±5, 000 km (2, 000 miles-3, 000 miles).
Filling the tank
The advertised fuel capacity of the fuel tank on your vehicle is equal to
the rated refill capacity of the fuel tank as listed in theRefill capacities
section of this chapter.
The advertised capacity is the amount of the indicated capacity and the
empty reserve combined. Indicated capacity is the difference in the
amount of fuel in a full tank and a tank when the fuel gauge indicates
empty. Empty reserve is the small amount of fuel remaining in the fuel
tank after the fuel gauge indicates empty.
The amount of usable fuel in the empty reserve varies and should
not be relied upon to increase driving range. When refueling your
vehicle after the fuel gauge indicates empty, you might not be
able to refuel the full amount of the advertised capacity of the
fuel tank due to the empty reserve still present in the tank.
For consistent results when filling the fuel tank:
²Turn the engine/ignition switch to the off position prior to refueling,
an error in the reading will result if the engine is left running.
²Use the same filling rate setting (low Ð medium Ð high) each time
the tank is filled.
²Allow no more than 2 automatic click-offs when filling.
²Always use fuel with the recommended octane rating.
²Use a known quality gasoline, preferably a national brand.
²Use the same side of the same pump and have the vehicle facing the
same direction each time you fill up.
²Have the vehicle loading and distribution the same every time.
Your results will be most accurate if your filling method is consistent.
