Warnings and Cautionsfor Using the FuelRequirements
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
other than a Mazda genuine
product, otherwise the emission
control system could be damaged.
Consult an Authorized Mazda Dealer
for details.
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.

Winter Driving
Carry emergency gear, including tire
chains, window scraper, flares, a small
shovel, jumper cables, and a small bag
of sand or salt.
Ask an Authorized Mazda Dealer to
check the following:
Have the proper ratio of antifreeze in
the radiator.
Refer to Inspecting the Coolant on
page 9-14.
Inspect the battery and its cables.
Cold reduces battery capacity.
Use an engine oil appropriate for the
lowest ambient temperatures that
the vehicle will be driven in (page
9-18).
Inspect the ignition system for
damage and loose connections.
Use washer fluid made with
antifreeze―but do not use engine
coolant antifreeze for washer fluid
(page 9-17).
When driving on ice or in water, snow,
mud, sand, or similar hazards:
Be cautious and allow extra distance
for braking.
Avoid sudden braking and sudden
maneuvering.
Do not pump the brakes. Continue
to press down on the brake pedal.
Refer to Antilock Brake System (ABS)
on page 5-84.
If you get stuck, select a lower gear
and accelerate slowly. Do not spin
the rear wheels.
For more traction in starting on
slippery surfaces such as ice or
packed snow, use sand, rock salt,
chains, carpeting, or other nonslip
material under the rear wheels.
NOTE
Remove snow before driving. Snow
left on the windshield is dangerous
as it could obstruct vision.
Do not apply excessive force to a
window scraper when removing ice
or frozen snow on the mirror glass
and windshield.
Never use warm or hot water for
removing snow or ice from windows
and mirrors as it could result in the
glass cracking.
Drive slowly. Braking performance
can be adversely affected if snow or
ice adheres to the brake
components. If this situation occurs,
drive the vehicle slowly, releasing the
accelerator pedal and lightly applying
the brakes several times until the
brake performance returns to
normal.
