2020 MAZDA MODEL 3 HATCHBACK tire pressure

Narrow lane roads due to road
construction or lane closures.
The vehicle ahead enters the radar
sensor's blind spot.
The vehicle ahead is running
abnormally due to accident or vehicle
damage.
Roads with repeated up and down
slopes
Driving on poor roads or unpaved
roads.
The distance between your vehicle
and the vehicle ahead is extremely
short.
A vehicle suddenly comes close such
as by cutting into the lane.
To prevent incorrect operation of the
system, use tires of the same specified
size, manufacturer, brand, and tread
pattern on all four wheels. In addition,
do not use tires with significantly
different wear patterns or tire pressures
on the same vehicle (Including the
temporary spare tire).
If the battery power is weak, the system
may not operate correctly.
When driving on roads with little traffic
and few vehicles ahead or obstructions
for the front radar sensor to detect,
“Safety and Driver Support Systems
Temporarily Disabled. Front Radar
Obscured. Drive Safely” may be
temporarily displayed, however, this
does not indicate a problem.
The radar sensors are regulated by the
relevant radio wave laws of the country
in which the vehicle is driven. If the
vehicle is driven abroad, authorization
from the country in which the vehicle is
driven may be required.
Front Side Radar Sensor*
▼Front Side Radar Sensor
Your vehicle is equipped with front side
radar sensor. The following systems also
use the front side radar sensor.
Front Cross Traffic Alert (FCTA)
The front side radar sensor function by
detecting the radio waves reflected off a
vehicle approaching from the front or an
obstruction sent from the radar sensor.
1. Front side radar sensor

The front side radar sensor are installed
inside the front bumper, one each on the
left and right sides.
Always keep the surface of the front
bumper near the front side radar sensor
clean so that the front side radar sensor
operate normally. Also, do not apply items
such as stickers.
Refer to Exterior Care on page 6-44.
CAUTION
If the front bumper receives a severe
impact, the system may no longer operate
normally. Stop the system immediately and
have the vehicle inspected at an
Authorized Mazda Dealer.

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 s
ensors installed on
each wheel via radio signal is received by
the receiver unit in t he 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 Vehic le 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, includ ing 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)
4-216
Mazda3_8HZ1-EA-19G_Edition1_old 2019-5-17 13:49:03

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 Pressu
re 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 tir e 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.
Refer to Tire Pressure Monitoring System
(TPMS) Warning Ind
ication/Warning
Light (Turns on) on page 7-36.
▼ 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 register the ID signal code of
the tire pressure s
ensor 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 havepassed, 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 s ensor 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 se nsor is installed to
a new wheel.
