Air sensor MAZDA MODEL 3 5-DOOR 2013 Owner's Manual

Black plate (196,1)
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.

3. After about 15 minutes, drive thevehicle 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
Ø 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.
Ø The 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.

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.

WARNING
Always securely and correctly tighten
the lug nuts:
Improperly or loosely tightened lug
nuts are dangerous. The wheel could
wobble or come off. This could result
in loss of vehicle control and cause a
serious accident.
Be sure to reinstall the same nuts you
removed or replace them with metric
nuts of the same configuration: Because the wheel studs and lug nuts
on your Mazda have metric threads,
using a non-metric nut is dangerous.
On a metric stud, it would not secure
the wheel and would damage the
stud, which could cause the wheel to
slip off and cause an accident.
5. Store the damaged tire, using the tire hold-down bolt to hold it in place.

7. Check the inflation pressure. Refer to Tires on page 10-12.
8. Have the flat tire repaired or replaced as soon as possible.
WARNING
Do not drive with any tires that have
incorrect air pressure: Driving on tires with incorrect air
pressure is dangerous. Tires with
incorrect pressure could affect
handling and result in an accident.
When you check the regular tires' air
pressure, check the spare tire, too.
NOTE
(With Tire Pressure Monitoring System)
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 (page 5-33).
NOTE
To prevent the jack and tool from rattling, store

CAUTION
Limited-Slip Differential system;
don't use the following:
ØTires not of the designated size
Ø Tires of different sizes or types at
the same time
Ø Tires not sufficiently inflated
If these instructions aren't followed,
the rotation of the left and right
wheels will be different and will thus
apply a constant load on the limited-
slip differential.
This will cause a malfunction.
q Replacing a Tire
WARNING
Always use tires that are in good
condition:
Driving with worn tires is dangerous.
Reduced braking, steering, and
traction could result in an accident.
Replace all four tires at the same time: Replacing just one tire is dangerous.
It could cause poor handling and
poor braking resulting in loss of
vehicle control. Mazda strongly
recommends that you replace all four
tires at the same time.
CAUTION
(With Tire Pressure Monitoring
System)
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
(With Tire Pressure Monitoring System)lWhen tires with steel wire reinforcement in
the sidewalls are used, the system may not
function correctly even with a genuine
wheel.
Refer to System Error Activation on page
5-35.
lBe sure to install the tire pressure sensors
whenever tires or wheels are replaced.
Refer to Tires and Wheels on page 5-35.
If a tire wears evenly, a wear indicator
will appear as a solid band across the
tread.
Replace the tire when this happens.
New tread

Worn tread
You should replace the tire before the
band crosses the entire tread.
NOTE
Tires degrade over time, even when they are
not being used on the road. It is recommended
that tires generally be replaced when they are
6 years or older. Heat caused by hot climates
or frequent high loading conditions can
accelerate the aging process. You should
replace the spare tire when you replace the
other road tires due to the aging of the spare
tire. The period in which the tire was
manufactured (both week and year) is
indicated by a 4-digit number.
