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
Before Driving
Fuel and Emission
3-30

SCHEDULED MAINTENANCE for the
details.
Refer to Scheduled Maintenance
(Europe) on page 6-3.
Refer to Scheduled Maintenance
(Except Europe) on page 6-6.
CAUTION
¾According to the inspection result of
scheduled maintenance, Mazda
genuine deposit cleaner is to be
used. Neglected deposits in the fuel
system may cause malfunction
indicator light coming on to indicate
an engine malfunction, and if the
vehicle continues to be driven under
this condition, it could result in
problems occurring such as idling
failure and poor acceleration.
¾The Mazda genuine deposit cleaner
is not a guarantee of engine
performance no matter the quality of
the fuel used. When a problem
occurs even though the
specified fuel
is used and the Mazda genuine
deposit cleaner is used according to
the instructions, consult an
Authorised Mazda Dealer.
¾If a deposit cleaner other than the
Mazda genuine product is used, it
could result in damage to the fuel
system or the engine internally;
therefore use only the Mazda
genuine product. Mazda genuine
deposit cleaner: K002 W0 001
¾If cleaning required according to the
inspection result of scheduled
maintenance is not done with the
Mazda genuine deposit cleaner,
repair cost for engine malfunctions
caused by deposits are borne by the
customer.
How to use the cleaner
With the fuel tank full, infuse 1 bottle
of Mazda genuine deposit cleaner
directly into the fuel tank.
NOTE
xInfusing the deposit cleaner when
the fuel tank is full provides the
concentration of cleaner within the
range
effective for removing the
deposits and the best cleaning
results can be obtained by the full
tank of fuel with the infused deposit
cleaner contacting the deposits for a
long period of time until the full tank
of fuel is nearly used up.
▼Fuel Requirements
(SKYACTIV-D
1.8)
The vehicle will operate efficiently on
diesel fuel with specification EN590 or
the equivalent.
CAUTION
¾Never use fuel other than
specification EN590 or the
equivalent for your vehicle. Use of
petrol or paraffin in diesel engines
will result in engine damage.
¾Never 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
When refuelling , always add at least 10
L (2.6 US gal, 2.2 Imp gal) of fuel.

Fuel-Filler Flap and Cap
▼Fuel-Filler Flap and Cap
WARNING
When removing the fuel-filler cap,
loosen the cap slightly and wait for
any hissing to stop, then remove it:
Fuel spray is dangerous. Fuel can burn
skin and eyes and cause illness if
ingested. Fuel spray is released when
there is pressure in the fuel tank and
the fuel-filler cap is removed too
quickly.
Before refuelling, stop the engine,
and always keep sparks and flames
away from the filler neck:
Fuel vapour is dangerous. It could be
ignited by sparks or flames causing
serious burns and injuries.
Additionally, use of the incorrect
fuel-filler cap or not using a fuel-filler
cap may result in a fuel leak, which
could result in serious burns or death
in an accident.
Do not continue refuelling after the
fuel pump nozzle shuts off
automatically:
Continuing to add fuel after the fuel
pump nozzle has shut off automatically
is dangerous because
overfilling the
fuel tank may cause fuel overflow or
leakage. Fuel overflow and leakage
could damage the vehicle and if the
fuel ignites it could cause a fire and
explosion resulting in serious injury or
death.
CAUTION
¾Always use only a designated Mazda
fuel-filler cap or an approved
equivalent, available at an expert
repairer (we recommend an
Authorised Mazda Repairer). The
wrong cap can result in a serious
malfunction of the fuel and emission
control systems.
¾When using an automatic car wash
or a high water pressure car washer,
lock the driver's door. Otherwise,
the
fuel-filler
flap may open
unexpectedly and could be
damaged.
▼Refuelling

CAUTION
When the engine coolant temperature
gauge needle is in the red range, the
engine coolant temperature is
extremely high. Drive slowly to reduce
engine load. If the engine coolant
temperature gauge needle is in the red
range, there is the possibility of
overheating. Park the vehicle in a safe
place immediately and take
appropriate measures.
Refer to Overheating on page 7-44.
NOTE
xIf the engine or engine coolant
temperature is high or low, the
engine output may be restricted to
protect the engine.
xDuring normal driving , the engine
coolant temperature stabilizes at 100
°C (210 °F) or less, and the gauge
indicates a range lower than 100 °C
(210 °F).
▼Fuel Gauge
The fuel gauge shows approximately
how much fuel is remaining in the tank
when the ignition is switched ON. We
recommend keeping the tank over 1/4
full.

1. Full
2. 1/4 Full
3. Empty

If the low fuel warning light illuminates
or the fuel level is very low, refuel as
soon as possible.
If inconsistency in engine performance
or stalling occurs due to low fuel level
conditions, refuel the vehicle as soon
as possible and add at least 10 L (2.7
US gal, 2.2 Imp gal) of fuel.
Refer to Low Fuel Warning Indication/
Warning Light on page 7-58.
NOTE
xAfter refuelling, it may require some
time for the indicator to stabilize. In
addition, the indicator may deviate
while driving on a slope or curve
since the fuel moves in the tank.

▼Outside Temperature Display
When the ignition is switched ON, the
outside temperature is displayed.

NOTE
xUnder the following conditions, the
outside temperature display may
differ from the actual outside
temperature depending on the
surroundings and vehicle conditions:
xSignificantly cold or hot
temperatures.
xSudden changes in outside
temperature.
xThe vehicle is parked.xThe vehicle is driven at low speeds.
Changing the Temperature Unit of the
Outside Temperature Display
The outside temperature unit can be
switched between Celsius and
Fahrenheit.
Settings can be changed by operating
the centre display screen.
Refer to the Settings section in the
Mazda Connect Owner's Manual.
NOTE
When the temperature unit indicated
in the outside temperature display is
changed, the temperature unit
indicated in the engine coolant gauge
display changes in conjunction with it.
Outside Temperature Warning*
When the outside temperature is low,
the indication flashes and a beep
sound is heard to warn the driver of
the possibility of icy roads.
If the outside temperature is lower
than about 4 °C (39 °F), the outside
temperature display and the
mark
flashes for about 3 seconds and a beep
sound is heard once.
NOTE
If the outside temperature is lower
than -20 °C (-4 °F), the beep sound
does not operate. However, the
mark illuminates.
▼Distance-to-empty
This displays the approximate distance
you can travel on the remaining fuel
based on the fuel economy.
The distance-to-empty will be
calculated and displayed every second.

NOTE
xEven though the distance-to-empty
display may indicate a
sufficient
amount of remaining driving distance
before refuelling is required, refuel as
soon as possible if the fuel level is
very low or the low fuel warning light
illuminates.
xThe display will not change unless
you add more than approximately 9
L (2.3 US gal, 1.9 Imp gal) of fuel.
