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)
4-205
CX-30_8HG6-EA-19I_Edition1_new 2019-6-13 18:45:11

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
7-27.
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.
▼When a tire pressure decreases
If the TPMS warning light turns on, a
tire pressure may be low. Inspect the
tire pressures and adjust them to the
correct inflation pressure.

▼Tires and Wheels
CAUTION
When inspecting/adjusting the tire
pressures, do not apply excessive force
to the air valve of the tire pressure
sensor. Otherwise, the tire pressure
sensor could be damaged.
When changing tires and wheels
When changing the tires or wheels
(such as installing winter tires), it will
be necessary to regi
ster the ID signal
code of the tire pressure sensor to the
TPMS.
Have an Authorized Mazda Dealer do
the registration or register the ID signal
codes of the tire pressure sensors using
the following procedure.
NOTE
The tire pressure sensors on each
wheel have a unique ID signal code.
For the TPMS to operate correctly, the
ID signal codes of the tire pressure
sensors need to be registered to the
system.
1. Wait more than 19 minutes after changing a tire or wheel.
2. After more than 19 minutes have passed, drive the vehicle at a speed
of about 25 km/h (16 mph) or
faster for 3 minutes or longer. While
driving , the ID signal codes of the
tire pressure sensors are
automatically registered.
NOTE
If you drive the vehicle within 19
minutes of changing a tire or wheel,
the TPMS warning light will flash
because the ID signal codes for the tire
pressure sensors were not registered.
In this case, stop the vehicle and
register the ID signal codes of the tire
pressure sensors following the
procedure.
When replacing tires and wheels
CAUTION
When replacing the tires and wheels,
consult an Authorized Mazda Dealer
Otherwise, the tire pressure sensors
could be damaged when replacing
them.
 Do not install non-genuine wheels. If
wheels other than genuine ones are
installed, it may not be possible to
install the tire pressure sensors.
When replacing a tire or wheel, always
install the tire pressure sensor. The
following combinations of tires,
wheels, or tires and wheels are
possible.
The tire pressure sensor from the old
wheel is removed and it is installed
to the new wheel.
Only a tire is replaced without
replacing the tire pressure sensor and
wheel.
A new tire pressure sensor is installed
to a new wheel.
NOTE
When installing a new tire pressure
sensor, the ID signal code for the tire
pressure sensor needs to be registered.
For details on purchasing a tire
pressure sensor and registering the ID
signal of the tire pressure sensor,
consult an Authorized Mazda Dealer.
