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.
Ø USE ONLY UNLEADED FUEL.
Ø Don't drive your Mazda with any sign of engine malfunction.
Ø Don't coast with the ignition switch turned off.
Ø Don't descend steep grades in gear with the ignition switch turned off.
Ø Don't operate the engine at high idle for more than 2 minutes.
Ø Don't tamper with the emission control system. All inspections and adjustments
must be made by a qualified technician.
Ø Don't 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.
