strong enough to inÀ ate the air bags,
all the doors and the liftgate are
automatically unlocked after about 6
seconds have elapsed from the time
of the accident.
 The doors and the liftgate may not
unlock depending on how an impact
is applied, the force of the impact,
and other conditions of the accident.

Before Driving
Doors and Locks
CAUTION
  Before opening the liftgate, remove
any snow and ice accumulation on
it. Otherwise, the liftgate could close
under the weight of the snow and ice
resulting in injury.
  Be careful when opening/closing
the liftgate during strong winds. If a
strong gust blows against the liftgate,
it could close suddenly resulting in
injury.
  Fully open the liftgate and make
sure that it stays open. If the liftgate
is only opened partially, it could
slam shut by vibration or wind gusts
resulting in injury.
  When loading or unloading luggage
in the luggage compartment, turn
off the engine. Otherwise, you could
get burned by the heat of the exhaust
gas.
  Be careful not to apply excessive
force to the damper stay on the
liftgate such as by putting your hand
on the stay. Otherwise, the damper
stay may bend and affect the liftgate
operation.
Damper stay

CAUTION
  Do not modify or replace the
liftgate damper stay. Consult an
expert repairer, we recommend an
Authorised Mazda Repairer if a
liftgate damper stay is deformed
or damaged for reasons such as a
collision or if there is some other
problem.

Fuel and Emission
Fuel and Engine Exhaust Precautions
Fuel Requirements (SKYACTIV-G 2.0)
Vehicles with catalytic converters or oxygen sensors must use ONLY UNLEADED FUEL,
which will reduce exhaust emissions and keep spark plug fouling to a minimum.

The vehicle will perform best with fuel listed in the table.

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

3–26
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.

Before Driving
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.
