▼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
fl
ammable:
Parking over or near anything
fl ammable, such as dry grass, is
dangerous. Even with the engine
turned o ff, 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 o ff.
 Do not descend steep grades in gear
with the ignition switched o ff.
 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
quali fied technician.
 Do not push-start or pull-start this
vehicle.
NOTE
Under U.S. federal law, any
modi fication to the
original-equipment emission control
system before the first sale and
registration of a vehicle is subject to
penalties. In some states, such modi fication made on a used vehicle
is also subject to penalties.
While the engine is o ff, 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 o ff.
