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.
Fuel Octane 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
ØUSE 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.
ØYour 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.
ØNever 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”.

Before Driving Your Mazda
Fuel and Engine Exhaust Precautions

Tire Pressure Monitoring Systemí
The tire pressure monitoring system (TPMS) monitors the pressure for each tire.
If tire pressure is too low in one or more tires, the system will inform the driver via the
warning light in the instrument panel and by the warning beep sound.
The tire pressure sensors installed on each wheel send tire pressure data by radio signal to
the receiver unit in the vehicle.
Tire pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tire temperatures are also lower.
When the tire temperature decreases, the air pressure decreases as well. The TPMS warning light
may illuminate more frequently. Visually inspect the tires daily before driving, and check tire
pressures monthly with a tire pressure gauge. When checking tire pressures, use of a digital tire
pressure gauge is recommended.
TPMS does not alleviate your need to check the pressure and condition of all four tires
regularly.
Driving Your Mazda
Starting and Driving
5-31íSome models.

Adjust the tire pressure to the correct tire
pressure. Refer to the specification charts
(page 10-12).
CAUTION
When replacing/repairing the tires or
wheels or both, have the work done
by an Authorized Mazda Dealer, or
the tire pressure sensors may be
damaged.NOTE
lPerform tire pressure adjustment when the
tires are cold. Tire pressure will vary
according to the tire temperature, therefore
let the vehicle stand for 1 hour or only drive
it 1.6 km (1 mile) or less before adjusting
the tire pressures. When pressure is
adjusted on hot tires to the cold inflation
pressure, the TPMS warning light/beep may
turn on after the tires cool and pressure
drops below specification.
Also, an illuminated TPMS warning light,
resulting from the tire air pressure dropping
due to cold ambient temperature, may turn
off if the ambient temperature rises. In this
case, it will also be necessary to adjust the
tire air pressures. If the TPMS warning
light illuminates due to a drop in tire air
pressure, make sure to check and adjust the
tire air pressures.
lAfter adjusting the tire air pressures, it may
require some time for the TPMS warning
light to turn off. If the TPMS warning light
remains illuminated, drive the vehicle at a
speed of at least 25 km/h (16 mph) for 10
minutes, and then verify that it turns off.
lTires lose air naturally over time and the
TPMS cannot tell if the tires are getting too
soft over time or you have a flat. However,
when you find one low tire in a set of four-
that is an indication of trouble; you should
have someone drive the vehicle slowly
forward so you can inspect any low tire for
cuts and any metal objects sticking through
tread or sidewall. Put a few drops of water
in the valve stem to see if it bubbles
indicating a bad valve. Leaks need to be
addressed by more than simply refilling the
trouble tire as leaks are dangerous - take it
to an Authorized Mazda Dealer which has
all the equipment to fix tires, TPMS systems
and order the best replacement tire for your
vehicle.

If the warning light illuminates again even
after the tire pressures are adjusted, there
may be a tire puncture. Replace the
punctured tire with the temporary spare
tire (page 7-9).
NOTE
A tire pressure sensor is not installed to the
temporary spare tire. The warning light will
flash continuously while the temporary spare
tire is being used.
Warning light flashes
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
qSystem Error Activation
When the TPMS warning light flashes,
there may be a system malfunction.
Consult an Authorized Mazda Dealer.
A system error activation may occur in
the following cases:
lWhen there is equipment or a device
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
lWhen using the following devices in
the vehicle that may cause radio
interference with the receiver unit.
lA digital device such as a personal
computer.
lA current converter device such as a
DC-AC converter.
lWhen excess snow or ice adheres to
the vehicle, especially around the
wheels.
lWhen the tire pressure sensor batteries
are exhausted.
lWhen using a wheel with no tire
pressure sensor installed.
lWhen using tires with steel wire
reinforcement in the side walls.
lWhen using tire chains.
qTires and Wheels
CAUTION
When inspecting or adjusting the tire
air pressures, do not apply excessive
force to the stem part of the wheel
unit. The stem part could be
damaged.
Changing tires and wheels
The following procedure allows the
TPMS to recognize a tire pressure sensor's
unique ID signal code whenever tires or
wheels are changed, such as changing to
and from winter tires.
NOTE
Each tire pressure sensor has a unique ID
signal code. The signal code must be
registered with the TPMS before it can work.
The easiest way to do it is to have an
Authorized Mazda Dealer change your tire and
complete ID signal code registration.
When having tires changed at an
Authorized Mazda Dealer
When an Authorized Mazda Dealer
changes your vehicle's tires, they will
complete the tire pressure sensor ID signal
code registration.
When changing tires yourself
If you or someone else changes tires, you
or someone else can also undertake the
steps for the TPMS to complete the ID
signal code registration.
1. After tires have been changed, switch
the ignition ON, then back to ACC or
OFF.
2. Wait for about 15 minutes.
Driving Your Mazda
Starting and Driving
5-35

3. After about 15 minutes, drive the
vehicle at a speed of at least 25 km/h
(16 mph) for 10 minutes and the tire
pressure sensor ID signal code will be
registered automatically.
NOTE
If the vehicle is driven within about 15 minutes
of changing tires, the tire pressure monitoring
system warning light will flash because the
sensor ID signal code would not have been
registered. If this happens, park the vehicle for
about 15 minutes, after which the sensor ID
signal code will register upon driving the
vehicle for 10 minutes.
Replacing tires and wheels
CAUTION
ØWhen replacing/repairing the tires
or wheels or both, have the work
done by an Authorized Mazda
Dealer, or the tire pressure sensors
may be damaged.
ØThe wheels equipped on your
Mazda are specially designed for
installation of the tire pressure
sensors. Do not use non-genuine
wheels, otherwise it may not be
possible to install the tire pressure
sensors.
Be sure to have the tire pressure sensors
installed whenever tires or wheels are
replaced.
When having a tire or wheel or both
replaced, the following types of tire
pressure sensor installations are possible.
lThe tire pressure sensor is removed
from the old wheel and installed to the
new one.
lThe same tire pressure sensor is used
with the same wheel. Only the tire is
replaced.
lA new tire pressure sensor is installed
to a new wheel.
NOTE
lThe tire pressure sensor ID signal code
must be registered when a new tire pressure
sensor is purchased. For purchase of a tire
pressure sensor and registration of the tire
pressure sensor ID signal code, consult an
Authorized Mazda Dealer.
lWhen reinstalling a previously removed tire
pressure sensor to a wheel, replace the
grommet (seal between valve body/sensor
and wheel) for the tire pressure sensor.

Blind Spot Monitoring (BSM) Systemí
The Blind Spot Monitoring (BSM) system is designed to assist the driver by monitoring
blind spots on both sides of the vehicle to the rear in certain situations such as when
changing lanes on roads and freeways.
The BSM system monitors the detection areas on both sides of the vehicle to the rear when
the vehicle speed is about 32 km/h (20 mph) or more, and notifies the driver of vehicles in
the detection area by illuminating the BSM warning light.
If the turn signal lever is operated in the direction the BSM warning light is illuminated, the
system warns the driver of the vehicle in the detection area with a beep sound.
Detection areas
WARNING
Do not rely completely on the BSM system and be sure to look over your shoulder
before changing lanes:
The BSM system can assist the driver in confirming the safety of the surroundings
but is not a complete substitute. The driver is responsible for assuring lane changes
and other maneuvers. Always pay attention to the direction in which the vehicle is
traveling and the vehicle's surroundings.
NOTE
lThe BSM system does not operate when the vehicle speed is lower than about 32 km/h (20 mph).lThe radar sensors are equipped inside the rear bumper. (page 5-40)lThe radar sensors do not detect human, animal, or static objects such as fences. In addition, the
system pauses when the selector lever is shifted to the R position. (The system resumes
automatically when the selector lever is shifted from the R position.)
Driving Your Mazda
Starting and Driving
5-37íSome models.

lThe detectability of the radar sensors has its limitations. The BSM system may not operate
properly under the following conditions:
lIce, snow, or soil adheres to the rear bumper surface around the radar sensors.lDuring adverse weather conditions such as rain or snow, or under conditions where water is
sprayed.
lThe rear bumper area around the radar sensors is blocked by foreign material (such as
stickers or a bicycle carrier).
lThe radar sensors may not detect all types of vehicles around your vehicle, especially the
following types of vehicles:
lMotorcycleslVehicles with body shapes that radar may not reflect such as a flatbed trailer with no cargo.lVehicles with lower body height such as sports cars.lHave the radar sensors inspected at an Authorized Mazda Dealer if any shock is applied to the
rear bumper, even in a minor accident. If the vehicle is driven with a damaged radar sensor, the
system may not operate properly resulting in an accident.
lFor repairs or paintwork around the radar sensors, or replacement of the bumper, consult an
Authorized Mazda Dealer.
lThe radar sensors of the BSM system may be regulated under the radio wave related laws of the
country where the vehicle is driven. The sensors in this system are approved for use in the U.S.A.
(including territories), Canada, and Mexico. If a vehicle with a BSM system is driven in a country
other than the U.S.A., Canada, or Mexico, the system has to be turned off using the BSM OFF
switch.
lThe detection area of the system has been determined based on the lane width of general
freeways. Therefore on a road with a narrower lane width, the system may detect vehicles on a
lane next to the adjacent lane and operate the warning light/beep. On a road with wider lane
width, the system may not detect vehicles on the adjacent lane and may not operate the warning
light/beep.
lOperation of the warning light/beep may be delayed or the system may not operate the warning
light/beep under the following conditions:
lThe vehicle accelerates from a standing-start with a vehicle alongside.lA vehicle moves from a lane two lanes over to the adjacent lane.lThe difference in vehicle speed between your vehicle and another vehicle is larger when
passing or being passed, and the vehicle passes the detection area within a short period of
time.
lOn a steep incline, or when there is a difference in height between lanes.lImmediately after the system has been activated by pressing the BSM OFF switch again after it
has been turned off (BSM OFF indicator light in instrument panel illuminates) by pressing the
switch.
lAlthough the system may detect objects on the road side such as parked vehicles or guardrails and
operate the warning light/beep, it does not indicate a malfunction.
lIf the vehicle is driven on a road with less traffic and few vehicles that the radar sensors can
detect, the system may pause (The BSM OFF indicator light in the instrument panel flashes).
However, it does not indicate a malfunction.
