¾The front radar sensor includes a
function for detecting soiling of the
radar sensor's front surface and
informing the driver, however,
depending on the conditions, it may
require time to detect or it may not
detect plastic shopping bags, ice or
snow. If this occurs, the system may
not operate correctly, therefore
always keep the front radar sensor
clean.
¾Do not install a grille guard.
¾If the front part of the vehicle has
been damaged in a vehicle accident,
the position of the front radar sensor
may have moved. Stop the system
immediately and always have the
vehicle inspected at an expert
repairer (we recommend an

¾Do not use the front bumper to push
other vehicles or obstructions such
as when pulling out of a parking
space. Otherwise, the front radar
sensor could be hit and its position
deviated.
¾Do not remove, disassemble, or
modify the front radar sensor.
¾For repairs, replacement or paint
work around the front radar sensor,
consult an expert repairer (we
recommend an Authorised Mazda
Repairer).¾Do not modify the suspensions. If
the suspensions are modified, the
vehicle's posture could change and
the front radar sensor may not be
able to correctly detect a vehicle
ahead or an obstruction.

Tyre Pressure Monitoring
System (TPMS)
*
▼Tyre Pressure Monitoring System
(TPMS)
The TPMS monitors the air pressure of
each tyre 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 tyre pressure sensors
installed on each wheel via radio signal
is received by the receiver unit in the
vehicle to monitor the tyre pressures.
1. Tyre pressure sensors

In addition, the current tyre pressures
can be checked using the centre
display.
Refer to the Vehicle Status Monitor
section in the Mazda Connect
Owner's Manual.
NOTE
xWhen the ambient temperature is
low, the tyre temperatures also
decrease. If the tyre temperatures
decrease, the air pressure in the tyres
will also decrease which could turn
on the TPMS warning light.
xBefore driving, visually inspect the
tyres for abnormalities. Additionally,
inspect the tyre pressures monthly. A
digital type air pressure gauge is
recommended for inspecting the tyre
pressures.
The TPMS is not a substitute for your
own periodic inspection of the tyres.
Always inspect the tyres yourself
periodically.
CAUTION
¾Each tyre, 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 tyre
inflation
pressure label. (If your vehicle has
tyres of a different size than the size
indicated on the vehicle placard or
tyre inflation pressure label, you
should determine the proper tyre
inflation pressure for those tyres.)
As an added safety feature, your
vehicle has been equipped with a
tyre pressure monitoring system
(TPMS) that illuminates a low tyre
pressure telltale when one or more
of your tyres is
significantly
under-inflated. Accordingly, when
the low tyre pressure telltale
illuminates, you should stop and
check your tyres as soon as possible,
and inflate them to the proper
pressure. Driving on a significantly
under-inflated tyre causes the tyre to
overheat and can lead to tyre failure.
Under-inflation also reduces fuel
efficiency and tyre tread life, and may
affect the vehicle's handling and
stopping ability.
When Driving
Tyre Pressure Monitoring System (TPMS)
4-232*Some models.

Please note that the TPMS is not a
substitute for proper tyre
maintenance, and it is the driver's
responsibility to maintain correct tyre
pressure, even if under-inflation has
not reached the level to trigger
illumination of the TPMS low tyre
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 tyre 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 tyre pressure as
intended. TPMS malfunctions may
occur for a variety of reasons,
including the installation of
replacement or alternate tyres or
wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more
tyres or wheels on your vehicle to
ensure that the replacement or
alternate tyres and wheels allow the
TPMS to continue to function
properly.
¾To avoid false readings, the system
samples for a little while before
indicating a problem. As a result it
will not instantaneously register a
rapid tyre deflation or blow out.▼If there is a problem with the Tyre
Pressure Monitoring System
(TPMS)
If the TPMS warning light flashes, there
may be a problem with the system.
Consult an expert repairer (we
recommend an Authorised Mazda
Repairer) to have the system inspected.
Refer to Tyre Pressure Monitoring
System (TPMS) Warning Indication/
Warning Light (Flashing) on page
7-57.
In the following cases, the system
cannot recognise the tyre pressures
correctly and the TPMS warning light
may flash.
xThere is equipment or a device
nearby emitting radio signals the
same as a tyre pressure sensor.
xA metallic object such as a
non-genuine electronic device is
installed near the centre of the
instrument panel (obstructs the radio
signals from the tyre pressure sensors
to the receiver).
xA device such as one of the following
is used in the cabin.
xElectronic devices such as a
computer.
xConverter devices such as a
DC-AC converter.
xThere is a large accumulation of
snow or ice around the vehicle tyres.
xThe battery in a tyre pressure sensor
is dead.
xA wheel not equipped with a tyre
pressure sensor is used.
xTyres employing steel in the sidewall
of the tyre are installed.
xTyre chains are used.
