The TJA may not be able to detect a
vehicle ahead depending on the type
of vehicle ahead and its conditions,
the weather conditions, and the road
conditions. Additionally, the system
might be unable to decelerate
sufficiently if a vehicle ahead applies
the brakes suddenly, another vehicle
cuts into the driving lane, or the difference in vehicle speed between
your vehicle and the vehicle ahead is
larger, which could result in an
accident. Check the surrounding
conditions and always drive carefully
while keeping a safe distance from
vehicles ahead and on-coming
vehicles.

For the purposes of safety, switch the
TJA off when it is not being used.
Leaving the TJA turned on when it is
not in use is dangerous as it could
operate unexpectedly, resulting in an
accident.

Do not use the TJA under the
following conditions. Otherwise, it
may result in an accident.
 General roads other than
expressways or highways (Driving
under these conditions using the TJA
is not possible.)
 Roads with sharp curves and where
vehicle traffic is heavy with
insufficient space between vehicles,
or roads where frequent and
repetitive acceleration and
deceleration occur (Driving under
these conditions using the TJA is not
possible). When entering and exiting
interchanges, service areas, and
parking areas of expressways (If you
exit an expressway while headway
control is in use, the vehicle ahead
will no longer be tracked and your
vehicle may accelerate to the set
speed).
 Slippery roads such as icy or
snow-covered roads (Tires could spin
causing you to lose vehicle control,
or the stop hold control may not
operate.)
 Long, descending slopes (to
maintain distance between vehicles,
the system automatically and
continuously applies the brakes
which could result in the loss of
brake power.)
 Two-wheeled vehicles such as
motorcycles or bicycles are ahead.
 (Automatic transmission vehicle)
Slopes with a steep gradient (The
vehicle ahead may not be detected
correctly, your vehicle may slip while
stopped by the stop hold control, or
it may accelerate suddenly after it
starts moving.)
 Driving under bad weather
conditions (rain, fog , and snow).
 The vehicle is driven on slippery
roads such as icy or snow -covered
roads and unpaved roads (Tires
could spin causing you to lose
vehicle control, or the stop hold
control may not operate.)
 Tires of a different specified size are
used, such as a temporary spare tire.
 Tires with insufficient tread are used.
 The tire pressures are not adjusted to
the
specified pressure.
 The vehicle is being used to tow a
camper or boat trailer.

Lane-keep Assist System(LAS)
*
▼Lane-keep Assist System (LAS)
The LAS provides steering assistance to
help the driver stay within the vehicle
lane if the vehicle might be deviating.
The forward sensing camera (FSC)
detects the white lines (yellow lines) of
the vehicle lane in which the vehicle is
traveling and if the system determines
that the vehicle may deviate from its
lane, it operates the electric power
steering to assist the driver’s steering
operation. The system also alerts the
driver by displaying an alert on the
multi-information display and the
active driving display. Use the system
when you drive the vehicle on roads
with white (yellow) lines such as
expressways and highways.
1. Forward sensing camera (FSC)
WARNING
Do not rely completely on the LAS:

The LAS is not an automated driving
system. In addition, the system is not
designed to compensate for a
driver’s lack of caution, and
over-reliance on the system could
lead to an accident.
The functions of the LAS have
limitations. Always stay on course
using the steering wheel and drive
with care.
 Do not use the LAS under the
following circumstances, otherwise it
may result in an accident.
 The vehicle is driven on slippery
roads such as icy or snow-covered
roads, and unpaved roads.
 Tires of a
different
specified size
are used, such as a temporary
spare tire.
 Tires with
insufficient tread are
used.
 The tire pressures are not adjusted
to the
specified pressure.
 The vehicle is being used to tow a
camper or boat trailer.
 Tire chains are used.
 The vehicle is driven on roads with
lane lines other than white (yellow)
lines, such as an expressway.
CAUTION
Heed the following cautions so that
the LAS can operate normally.
Do not modify the vehicle's
suspensions.
 Always use tires of the specified type
and size for the front and rear
wheels. Consult an Authorized
Mazda Dealer for tire replacement.

NOTE
When the vehicle is driven on roads
in which there is an elevated road on
one side, the front radar sensor
function may be restricted
temporarily.
Under the following conditions, the
front radar sensor may not be able to
detect vehicles ahead or obstructions
correctly and each system may not
operate normally.
The rear surface of a vehicle ahead
does not reflect radio waves
effectively, such as an unloaded
trailer or an automobile with a
loading platform covered by a soft
top, vehicles with a hard plastic
tailgate, and round-shaped
vehicles.
Vehicles ahead with low vehicle
height and thus less area for
reflecting radio waves.
Visibility is reduced due to a
vehicle ahead casting off water,
snow, or sand from its tires and
onto your windshield.
The luggage compartment is
loaded with heavy objects or the
rear passenger seats are occupied.
Ice, snow, or soiling is on the front
surface of the front emblem.
During inclement weather such as
rain, snow, or sand storms.
When driving near facilities or
objects emitting strong radio
waves.
Under the following conditions, the
front radar sensor may not be able to
detect vehicles ahead or
obstructions.
The beginning and end of a curve.Roads with continuous curves.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 your 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.

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)
4-213
CX-30_8JP5-EA-20K_Edition1_new 2020-7-22 15:50:09

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
7-28.
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.
Refer to Tire Pressure Monitoring
System (TPMS) Warning Indication/
Warning Light (Turns on) on page
7-32.
▼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.

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.
