Fuel with a lower rating will negatively affect the emission control system
performance and could also cause engine knocking and serious engine damage.

CAUTION
¾USE 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.
¾The 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.
¾Never add fuel system additives other than a Mazda genuine product, 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.
xRefuelling using the same-type fuel is recommended.xAdd 16 L (4.2 US gal, 3.5 Imp gal) or more of fuel when refuelling.xDrive 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.
▼Deposit Cleaner
To get the best performance out of our
newest-technology SKYACTIV petrol
engines, cleaning of deposits adhering
to the fuel related system, such as fuel
injectors, may be required by using a
Mazda genuine deposit cleaner in the
specified countries. Refer to

▼Emission Control System
(SKYACTIV-G 2.0, SKYACTIV-G
2.5, SKYACTIV-X 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
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.
¾USE ONLY UNLEADED FUEL.
¾Do not drive your Mazda with any
sign of engine malfunction.
¾Do not coast with the ignition
switched off.
¾Do not descend steep grades in gear
with the ignition switched off.
¾Do not operate the engine at high
idle for more than 2 minutes.
¾Do not tamper with the emission
control system. All inspections and
adjustments must be made by a
qualified technician.
¾Do not push-start or pull-start this
vehicle.
