Tire Pressure MonitoringSystem (TPMS)
▼Tire Pressure Monitoring System
(TPMS)
The TPMS monitors the air pressure of
each tire and if it decreases below the
specified
value, the system
notifies the
driver by turning on the TPMS warning
light in the instrument cluster and
indicating a message on the
multi-information display.
For the TPMS, the air pressure data
sent from the tire pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tire pressures.
1. Tire pressure sensors

In addition, the current tire pressures
can be checked using the center
display.
Refer to the Vehicle Status Monitor
section in the Mazda Connect
Owner's Manual.
NOTE
When the ambient temperature is
low, the tire temperatures also
decrease. If the tire temperatures
decrease, the air pressure in the tires
will also decrease which could turn
on the TPMS warning light.
Before driving, visually inspect the
tires for abnormalities. Additionally,
inspect the tire pressures monthly. A
digital type air pressure gauge is
recommended for inspecting the tire
pressures.
The TPMS is not a substitute for your
own periodic inspection of the tires.
Always inspect the tires yourself
periodically.
CAUTION
 Each tire, including the spare (if
provided), should be checked
monthly when cold and
inflated to
the inflation pressure recommended
by the vehicle manufacturer on the
vehicle placard or tire inflation
pressure label. (If your vehicle has
tires of a different size than the size
indicated on the vehicle placard or
tire inflation pressure label, you
should determine the proper tire inflation pressure for those tires.)
As an added safety feature, your
vehicle has been equipped with a
tire pressure monitoring system
(TPMS) that illuminates a low tire
pressure telltale when one or more
of your tires is significantly
under-inflated. Accordingly, when
the low tire pressure telltale
illuminates, you should stop and
check your tires as soon as possible,
and inflate them to the proper
pressure. Driving on a significantly
under-inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
When Driving
Tire Pressure Monitoring System (TPMS)
4-229
Mazda3_8KH1-EA-21K_Edition1_new 2021-7-27 16:02:22

Please note that the TPMS is not a
substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tire
pressure telltale.
Your vehicle has also been equipped
with a TPMS malfunction indicator to
indicate when the system is not
operating properly.
The TPMS malfunction indicator is
combined with the low tire pressure
telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then
remain continuously illuminated.
This sequence will continue upon
subsequent vehicle start-ups as long
as the malfunction exists. When the
malfunction indicator is illuminated,
the system may not be able to detect
or signal low tire pressure as
intended. TPMS malfunctions may
occur for a variety of reasons,
including the installation of
replacement or alternate tires or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tires or wheels on your vehicle to
ensure that the replacement or
alternate tires and wheels allow the
TPMS to continue to function
properly.
 To avoid false readings, the system
samples for a little while before
indicating a problem. As a result it
will not instantaneously register a
rapid tire deflation or blow out.▼ If there is a problem with the Tire
Pressure Monitoring System
(TPMS)
If the TPMS warning light flashes, there
may be a problem with the system.
Consult an Authorized Mazda Dealer
to have the system inspected.
Refer to Tire Pressure Monitoring
System (TPMS) Warning Indication/
Warning Light (Flashing) on page
7-33.
In the following cases, the system
cannot recognize the tire pressures
correctly and the TPMS warning light
may
flash.
There is equipment or a device
nearby emitting radio signals the
same as a tire pressure sensor.
A metallic object such as a
non-genuine electronic device is
installed near the center of the
dashboard (obstructs the radio
signals from the tire pressure sensors
to the receiver).
A device such as one of the following
is used in the cabin.
Electronic devices such as a
computer.
Converter devices such as a
DC-AC converter.
There is a large accumulation of
snow or ice around the vehicle tires.
The battery in a tire pressure sensor
is dead.
A wheel not equipped with a tire
pressure sensor is used.
Tires employing steel in the sidewall
of the tire are installed.
Tire chains are used.

Anything which generates ultrasonic waves such as another vehicle's horn, the
engine sound of a motorcycle, the air brake sound of a large-sized vehicle, or
another vehicle's sensors approaches the vehicle.
The vehicle is driven in heavy rain or in road conditions causing water-splash.A commercially-available fender pole or an antenna for a radio transmitter is
installed to the vehicle.
The vehicle is moving towards a tall or square curbstone, or a steep grade.An obstruction is too close to the sensor.The vehicle is moving towards an uneven wall or stairs.There are multiple obstructions.The vehicle is driven in a place with low ceilings.Obstructions under the bumper cannot be detected. Obstructions which are
lower than the sensor or thin may not be detected even though they were
detected once.
The following types of obstructions may not be detected:
Thin objects such as wire, rope or polesThings which absorb sonic waves easily such as cotton or snowAngular shaped objectsVery tall objects, and those which are wide at the topSmall, short objectsAlways have the system inspected at an Authorized Mazda Dealer if any shock is
applied to the bumpers, even in a minor accident. If the sensors are deviated, they
cannot detect obstructions.
The system may have a malfunction if a sound is not activated or the detection
indication is not displayed even when th e parking sensor OFF switch is pressed
and the parking sensor is operable. Have your vehicle inspected by an Authorized
Mazda Dealer.
The system may have a malfunction if the indicator light does not turn on even
when the parking sensor OFF switch is turned on. Have your vehicle inspected by
an Authorized Mazda Dealer.
The system may have a malfunction if a message indicating a system malfunction is
displayed. Have your vehicle inspected by an Authorized Mazda Dealer.
A message may be displayed even when the ambient temperature is extremely
cold, or mud, ice, or snow adheres to the sensor area. Remove any foreign matter
from the sensor area.
When installing a trailer hitch, consult an Authorized Mazda Dealer.If a Mazda genuine trailer hitch is used, the rear side of the parking sensor system
