Fuel and Emission
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.
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.

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 system. All inspections and adjustments must
be made by a qualified technician.

Do not 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.

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.
