Fuel Requirements
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.
MZR 2.3 DISI Turbo
Your Mazda will perform best with fuel listed in the table.
FuelOctane Rating*(Anti-knock index)
Premium unleaded fuel 91 [ (R
M)/2 method] or above (96 RON or above)
* U.S. federal law requires that octane ratings be posted on gasoline station pumps.
This vehicle is designed for and requires use of premium unleaded fuel. If 91 octane fuel [
(R
M)/2 method] (96RON) is not available, gasoline as low as 87 octane [ (RM)/2
method] (91RON) can be used temporarily for emergency purposes. Use of gasoline lower
than 91 octane [ (R
M)/2 method] (96RON) can decrease performance during its use.
Refueling the vehicle with the correct octane fuel a couple of times will restore vehicle
performance.
SKYACTIV-G 2.0, MZR 2.0 and MZR 2.5
Your Mazda 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 ratings be posted on gasoline station pumps.
Fuel with a rating lower than 87 octane (91 RON) could cause the emission control system
to lose effectiveness. It could also cause engine knocking and serious engine damage.
CAUTION
Ø 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.
Ø Your vehicle can only use oxygenated fuels containing no more than 10 % ethanol
by volume. Damage to your vehicle may occur when ethanol exceeds this
recommendation, or if the gasoline contains any methanol. Stop using gasohol of
any kind if your vehicle engine is performing poorly.
Ø Never add fuel system additives. 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 ”.

Break-In Period
No special break-in is necessary, but a few
precautions in the first 1,000 km (600
miles) may add to the performance,
economy, and life of your Mazda.
lDo not race the engine.lDo not maintain one constant speed,
either slow or fast, for a long period of
time.
lDo not drive constantly at full-throttle
or high engine rpm for extended
periods of time.
lAvoid unnecessary hard stops.lAvoid full-throttle starts.
Money-Saving Suggestions
How you operate your Mazda determines
how far it will travel on a tank of fuel. Use
these suggestions to help save money on
fuel and repairs.
lAvoid long warm-ups. Once the engine
runs smoothly, begin driving.
lAvoid fast starts.lKeep the engine tuned. Follow the
maintenance schedule (page 8-4) and
have an Authorized Mazda Dealer
perform inspections and servicing.
lUse the air conditioner only when
necessary.
lSlow down on rough roads.lKeep the tires properly inflated.lDo not carry unnecessary weight.lDo not rest your foot on the brake
pedal while driving.
lKeep the wheels in correct alignment.lKeep windows closed at high speeds.lSlow down when driving in crosswinds
and headwinds.
WARNING
Never stop the engine when going
down a hill:Stopping the engine when going
down a hill is dangerous. This causes
the loss of power steering and power
brake control, and may cause
damage to the drivetrain. Any loss of
steering or braking control could
cause an accident.

Windshield Wipers and
Washer
The ignition must be switched ON.
WARNING
Use only windshield washer fluid or
plain water in the reservoir:Using radiator antifreeze as washer
fluid is dangerous. If sprayed on the
windshield, it will dirty the
windshield, affect your visibility, and
could result in an accident.
Only use windshield washer fluid
mixed with anti-freeze protection in
freezing weather conditions: Using windshield washer fluid
without anti-freeze protection in
freezing weather conditions is
dangerous as it could freeze on the
windshield and block your vision
which could cause an accident.
In addition, make sure the
windshield is sufficiently warmed
using the defroster before spraying
the washer fluid. NOTE
Because heavy ice and snow can jam the wiper
blades, the wiper motor is protected from
motor breakdown, overheating and possible
fire by a circuit breaker. This mechanism will
automatically stop operation of the blades, but
only for about 5 minutes.
If this happens, turn off the wiper switch and
park off the right-of-way, and remove the snow
and ice.
After 5 minutes, turn on the switch and the
blades should operate normally. If they do not
resume functioning, consult an Authorized
Mazda Dealer as soon as possible. Drive to
the side of the road and park off the right-of-
way. Wait until the weather clears before trying
to drive with the wipers inoperative.

Operating Tips
qOperating the Climate Control
System
Operate the climate control system with
the engine running.
NOTE
To prevent the battery from being discharged,
do not leave the fan control dial on for a long
period of time with the ignition switched ON
when the engine is not running.
qClearing the Air Inlet
Clear all obstructions such as leaves,
snow and ice from the hood and the air
inlet in the cowl grille to improve the
system efficiency.
qFoggy Windows
The windows may fog up easily in humid
weather. Use the climate control system to
defog the windows.
To help defog the windows, operate the
air conditioner to dehumidify the air.
NOTE
The air conditioner may be used along with the
heater to dehumidify the air.
qParking in Direct Sunlight
If the vehicle has been parked in direct
sunlight during hot weather, open the
windows to let warm air escape, then run
the climate control system.
qNot Using for a Long Period
Run the air conditioner about 10 minutes
at least once a month to keep internal
parts lubricated.
qCheck the Refrigerant before the
Weather Gets Hot
Have the air conditioner checked before
the weather gets hot. Lack of refrigerant
may make the air conditioner less
efficient. Consult an Authorized Mazda
Dealer for refrigerant inspection.
The air conditioner is filled with
HFC134a (R134a), a refrigerant that will
not damage the ozone layer.
If the air conditioner is low on refrigerant
or has a malfunction, consult an
Authorized Mazda Dealer.
qReplacement of the Cabin Air
Filterí
Your vehicle is equipped with an air filter
for the air conditioner. It is necessary to
change the filter periodically as indicated
in scheduled maintenance (page 8-4).
Consult an Authorized Mazda Dealer for
replacement of the cabin air filter.
