qEmission 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
lUnder 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.
lWhile the engine is off, the sound of a valve opening and closing can be heard at the rear of the
right side 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.

qEngine 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.

Fuel-Filler Lid and Cap
WARNING
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 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
equivalent, 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.
qFuel-Filler Lid
To open, pull the remote fuel-filler lid
release.

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.
