▼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.
WA R N I N G
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 this
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.
▼ Engine Exhaust (Carbon monoxide)
WA R N I N G
Do not drive your vehicle if you smell
exhaust gas inside the vehicle:
Engine exhaust gas is dangerous. This gas
contains carbon mono
xide (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.
