CAUTION
  USE ONLY UNLEADED FUEL.  Leaded fuel is harmful to the catalytic converter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
  The use of E10 fuel with 10 % ethanol in Europe is safe for your vehicle. Damage to
your vehicle may occur when ethanol exceeds this recommendation.
  Never add fuel system additives, otherwise the emission control system could be
damaged. Consult an expert repairer, we recommend an Authorised Mazda Repairer

Emission Control System (SKYACTIV-G 1.3, SKYACTIV-G 1.5)
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 À ammable:
Parking over or near anything À ammable, 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 À ammable. A resulting ¿ re 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.
