Door Locks
WA R N I N G
Always take all children and pets with you
or leave a responsible person with them:
Leaving a child or a pet unattended in a
parked vehicle is dangerous. In hot
weather, temperatures inside a vehicle can
become high enough to cause brain
damage or even death.
Do not leave the key in your vehicle with
children and keep them in a place where
your children will not find or play with
them:
Leaving children in a vehicle with the key is
dangerous. This could result in someone
being badly injured or even killed.
Keep all doors locked when driving:
Unlocked doors in a moving vehicle are
dangerous. Passengers can fall out if a
door is accidentally opened and can more
easily be thrown out in an accident.
Always close all the windows and
moonroof, lock the doors and the liftgate
and take the key with you when leaving
your vehicle unattended:
Leaving your vehicle unlocked is dangerous
as children could lock themselves in a hot
vehicle, which could result in death. Also, a
vehicle left unlocked becomes an easy
target for thieves and intruders.
After closing the doors and the liftgate,
always verify that they are securely closed:
Doors and the liftgate not securely closed
are dangerous, if the vehicle is driven with
a door and the liftgate not securely closed,
the door and the liftgate could open
unexpectedly resulting in an accident.
Always confirm the safety around the
vehicle before opening a door and the
liftgate:
Suddenly opening a door and the liftgate is
dangerous. A passing vehicle or a
pedestrian could be hit and cause an
accident.
CAUTION
Always confirm the conditions around
the vehicle before opening/closing the
doors and the liftgate and use caution
during strong winds or when parked on
an incline. Not being aware of the
conditions around the vehicle is
dangerous because fingers could get
caught in the door and the liftgate or a
passing pedestrian could be hit, resulting
in an unexpected accident or injury.
NOTE
Always stop the engine and lock the
doors. In addition, to prevent theft of
valuables, do not leave them inside the
cabin.

Liftgate
WA R N I N G
Never allow a person to ride in the luggage
compartment:
Allowing a person to ride in the luggage
compartment is dangerous. The person in
the luggage compartment could be
seriously injured or killed during sudden
braking or a collision.
Do not drive with the liftgate open:
Exhaust gas in the cabin of a vehicle is
dangerous. An open liftgate in a moving
vehicle will cause exhaust gas to be drawn
into the cabin. This gas contains CO
(carbon monoxide), which is colorless,
odorless, and highly poisonous, and it can
cause loss of consciousness and death.
Moreover, an open liftgate could cause
occupants to fall out in an accident.
Do not stack or leave loaded luggage
unsecured in the luggage compartment:
Otherwise, the luggage may move or
collapse, resulting in injury or an accident.
In addition, do not load luggage higher
than the seatbacks. It may affect the side or
rear field of view.
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

Do not modify or replace the liftgate
damper stay. Consult an Authorized
Mazda Dealer if a liftgate damper stay is
deformed or damaged for reasons such
as a collision or if there is some other
problem.

Fuel and Engine Exhaust Precautions
▼Fuel Requirements (SKYACTIV-G 2.0, SKYACTIV-G 2.5, SKYACTIV-G 2.5T)
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.

This vehicle will perform best with fuel listed in the table.
Fuel
Octane Rating* (Anti-knock index)
Regular unleaded fuel 87 [(R
M)/2 method] or above (91 RON or above)
U.S. federal law requires that octane ra
tings be posted on gasoline station pumps.
Fuel with a rating lower than 87 octane (91 R ON) will negatively affect the emission control
system performance and could also cause engine knocking and serious engine damage.
CAUTION
USE ONLY UNLEADED FUEL.
Leaded fuel is harmful to the catalytic co nverter and oxygen sensors and will lead to
deterioration of the emission control system and or failures.
 This vehicle can only use oxygenated fuels containing no more than 10 % ethanol by
volume. Damage to the vehicle may occur when ethanol exceeds this recommendation, or
if the gasoline contains any methanol. Stop us ing gasohol of any kind if your vehicle engine
is performing poorly.
 Never add fuel system additive s, otherwise the emission control system could be damaged.
Consult an Authorized Mazda Dealer for details.
Gasoline blended with oxygenates such as alcohol or ether compounds are generally
referred to as oxygenated fuels. The common gasoline blend that can be used with your
vehicle is ethanol blended at no more than 10 %. Gasoline containing alcohol, such as
ethanol or methanol, may be marketed under the name "Gasohol".

Vehicle damage and drivability problems resulting from the use of the following may not be
covered by the warranty.
Gasohol containing more than 10 % ethanol.
Gasoline or gasohol containing methanol.
Leaded fuel or leaded gasohol.

▼Fuel Requirements (SKYACTIV-D 2.2)
The vehicle will operate efficiently on diesel fuel with specification Ultra-Low Sulfur Diesel
(ULSD, 15 ppm sulfur or less) fuel that meets the ASTM D975 standard or the equivalent.
Fuel grade labels are visible on fuel-filler lid, therefore, verify the fuel grade before
refueling. If the fuel grade cannot be verified, ask the gas station attendant.
CAUTION

Never use fuel other than specification Ultra-Low Sulfur Diesel (ULSD, 15 ppm sulfur or less)
fuel that meets the ASTM D975 standard or the equivalent for your vehicle. Use of gasoline
or kerosene in diesel engines will resu lt in fuel system and engine damage.
 Never use diesel fuel with concentrations of methyl ester bio-diesel higher than 5 % (B5),
such as B20 or B100.
 Never add fuel system additives. Otherwise, the emission control system could be damaged.
 If any type of incorrect fuel is accidently pu mped into the fuel tank, do not turn on the
engine and drive the vehicle, and co nsult an Authorized Mazda Dealer.
Turning on the engine or driving the vehicle with the incorrect fuel could cause damage to
the fuel pump and fuel injectors.
 Do not mistake the refueling port for the DEF filler port. If fuel was added to the DEF filler
port by mistake, do not turn on the engine and drive the vehicle, and consult an Authorized
Mazda Dealer.
Turning on the engine or driving the vehicle with fuel in the DEF filler port could cause
damage to the emission control system.

Low outside temperatures
When the outside temperature is low, diesel fuel (light oil) may freeze and clog the fuel
pipe, leading to problems such as the engine not starting. When driving to a cold region, add
winter grade diesel fuel as soon as possible.
WA R N I N G
Never use engine starting assist additives:
Using engine starting assist additives is dangerous because they may cause a vehicle
explosion or a vehicle runaway condition, leading to serious injury or death.
▼ Emission Control System (SKYACTIV-G 2.0, SKYACTIV-G 2.5, SKYACTIV-G
2.5T)
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.
WA R N I N G
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.
 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.

About the SCR system
WA R N I N G
Be careful not to allow the DEF to run out. If the DEF completely runs out, the SCR system will
not operate normally:
If the vehicle runs out of DEF, the vehicle speed is restricted in steps to prevent contaminants
from being exhausted. When the remaining dist ance-to-empty reaches 0 km (0 miles) in the
final stage, the engine is forced
to idle. For replenishment of the DEF supply, consult an
Authorized Mazda Dealer.
CAUTION
Use a Mazda genuine product or a product conforming to ISO22241-1 for DEF. If
incompatible DEF is used, the SCR system may not operate normally. For the recommended
DEF, consult the nearest Authorized Mazda Dealer.
NOTE
When the remaining distance-to-empty is 640 km (400 miles) or shorter while the DEF
warning indication is displayed, the SCR warning light turns on and the vehicle speed is
restricted. In addition, if there is a problem with the SCR system/DEF and the remaining
distance-to-empty is 200 km (125 miles) or sh orter, the SCR warning light flashes and the
vehicle speed is restricted.
DEF needs to be replenished periodically according to the scheduled maintenance
information. If a warning message is displa yed in the multi-information display or the
SCR warning light flashes, consult an Authorized Mazda Dealer.
Normally, the vehicle can be driven about 12,000 km (7,500 miles) before the DEF needs
to be replenished.
