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.
xFront 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 sensors are
installed inside the front bumper, one
on each side.
Always keep the surface of the front
bumper near the front side radar
sensors clean so that they operate
normally. Also, do not apply items such
as stickers.
Refer to Exterior Care on page 6-54.
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 expert repairer (we
recommend an Authorised Mazda
Repairer).

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.

Ty re s
▼Ty re s
For reasons of proper performance,
safety, and better fuel economy, always
maintain recommended tyre
inflation
pressures and stay within the
recommended load limits and weight
distribution.
WARNING
Using
Different Ty re Ty p e s :
Driving your vehicle with different
types of tyres is dangerous. It could
cause poor handling and poor braking;
leading to loss of control.
Except for the limited use of the
temporary spare tyre, use only the
same type tyres (radial, bias-belted,
bias-type) on all four wheels.
Using Wrong-Sized Tyres:
Using any other tyre size than what is
specified for the vehicle (page 9-10)
is dangerous. It could seriously affect
ride, handling, ground clearance, tyre
clearance, and speedometer
calibration. This could cause you to
have an accident. Use only tyres that
are the correct size specified for the
vehicle.
▼Tyre Inflation Pressure
WARNING
Always inflate the tyres to the correct
pressure:
Overinflation or underinflation of tyres
is dangerous. Adverse handling or
unexpected tyre failure could result in
a serious accident.
Refer to Tyres on page 9-10.
Use only a Mazda-genuine tyre valve
cap:
Use of a non-genuine part is
dangerous as the correct tyre air
pressure cannot be maintained if the
tyre valve becomes damaged. If the
vehicle is driven under this condition,
the tyre air pressure will decrease
which could result in a serious
accident. Do not use any part for the
tyre valve cap that is not a
Mazda-genuine part.
Inspect all tyre pressures monthly when
the tyres are cold. Maintain
recommended pressures for the best
ride, handling, and minimum tyre
wear.
Refer to the specification charts (page
9-10).
NOTE
xAlways check tyre pressure when
tyres are cold.
xWarm tyres normally exceed
recommended pressures. Do not
release air from warm tyres to adjust
the pressure.
xUnderinflation can cause reduced
fuel economy, uneven and
accelerated tyre wear, and poor
sealing of the tyre bead, which will
deform the wheel and cause
separation of tyre from rim.
xOverinflation can produce a harsh
ride, uneven and accelerated tyre
wear, and a greater possibility of
damage from road hazards.
Keep your tyre pressure at the correct
levels. If one frequently needs
inflating, have it inspected.
