Before Driving
Fuel and Emission
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
for details.
NOTE
(Premium unleaded fuel (within E85))
To maintain good engine startability and performance, the following points must be
observed.
 
 Refuelling using the same-type fuel is recommended. 
 Add 16 L (4.2 US gal, 3.5 Imp gal) or more of fuel when refuelling. 
 Drive the vehicle 10 km (6.2 mile) or more just after refuelling to allow the vehicle's
engine control system to learn the ethanol concentration accurately.
Fuel Requirements (SKYACTIV-D 1.5)
The vehicle will operate ef¿ ciently on diesel fuel with speci¿ cation EN590 or the
equivalent.
CAUTION
  Never use fuel other than speci¿ cation EN590 or the equivalent for your vehicle. Use
of petrol or paraf¿ n in diesel engines will result in engine damage.

 Never add fuel system additives. Otherwise, the emission control system could be
damaged. Consult an expert repairer, we recommend an Authorised Mazda Repairer
for details.

Fuel and Emission
NOTE
When refuelling, always add at least 10 L (2.6 US gal, 2.2 Imp gal) of fuel.
Emission Control System (SKYACTIV-G 2.0)
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.
 
 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 quali¿ ed technician.

 Do not push-start or pull-start your vehicle.
