Radar Sensors (Rear)*
Your vehicle is equipped with radar sensors (rear). The followi ng systems also use the radar
sensors (rear).
•Blind Spot Monitoring (BSM)
•Rear Cross Traffic Alert (RCTA)
The radar sensors (rear) function by detecting the radio waves reflected off a vehicle
approaching from the rear or an obstruction sent from the radar sensor.
Radar sensors (rear)
The radar sensors (rear) are installed inside the rear bumper, one each on the left and right
sides.
Always keep the surface of the rear bumper near the radar sensors (rear) clean so that the
radar sensors (rear) operate normally. Also, do not apply items such as stickers.
Refer to Exterior Care on page 6-61.
CAUTION
If the rear 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.
NOTE
•The detection ability of the radar sensors (r ear) has limitations. In the following cases,
the detection ability may lower and the system may not operate normally.
•The rear bumper near the radar sensors (rear) has become deformed.
•Snow, ice or mud adheres to the radar sensors (rear) on the rear bumper.
•Under bad weather conditions such as rain, snow and fog.
•Under the following conditions, the radar sensors (rear) cannot detect target objects or it
may be difficult to detect them.
•Stationary objects on a road or a road side such as small, two-wheeled vehicles,
bicycles, pedestrians, animals, and shopping carts.

•Vehicle shapes which do not reflect radar waves well such as empty trailers with a low
vehicle height and sports cars.
•Vehicles are shipped with the direction of the radar sensors (rear) adjusted for each
vehicle to a loaded vehicle condition so that the radar sensors (rear) detect approaching
vehicles correctly. If the direction of the radar sensors (rear) has deviated for some
reason, have the vehicle inspected at an expert repairer, we recommend an Authorised
Mazda Repairer.
•For repairs or replacement of the radar sensors (rear), or bumper repairs, paintwork, and
replacement near the radar sensors, consult an expert repairer, we recommend an
Authorised Mazda Repairer.
•Turn off the system while pulling a trailer or while an accessory such as a bicycle carrier
is installed to the rear of the vehicle. Otherwise, the radio waves emitted by the radar will
be blocked causing the system to not operate normally.
•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.

Tyre Pressure Monitoring System*
The Tyre Pressure Monitoring System (TPMS) monitors the pressure for each tyre.
If tyre pressure is too low in one or more tyres, the system wi ll inform the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Warning Indication/Warning Lights on page 4-42.
Refer to Tyre Inflation Pressu re Warning Beep on page 7-66.

The tyre pressure sensors installed on each wheel send tyre pressure data by radio signal to
the receiver unit in the vehicle.
Tyre pressure sensors
NOTE
When the ambient temperature is low due to seasonal changes, tyre temperatures are also
lower. When the tyre temperature decreases, the air pressure decreases as well. The TPMS
warning light may illumina te more frequently. Visually inspect the tyres daily before driving,
and check tyre pressures monthly with a tyre pressure gauge. When checking tyre pressures,
use of a digital tyre pressure gauge is recommended.

TPMS does not alleviate your need to check the pressure and con dition of all four tyres
regularly.
CAUTION
 Each 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 pressu re telltale when one or more of your tyres is
significantly under-inflated. Accordingly, wh en 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-infla ted tyre causes the tyre to overheat and can
lead to tyre failure. Under-inflation also reduc es fuel efficiency and tyre tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tyre maintenance, and it is the
driver's responsibility to maintain correct ty re 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 wi ll 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 th at prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale af ter 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.
 To avoid false readings, the system samples for a little while before indicating a problem. As
a result it will not instantaneously regi ster a rapid tyre deflation or blow out.
▼System Error Activation
When the warning light flashes, there may
be a system malfunction. Consult an
Authorised Mazda Dealer.
A system error activation may occur in the
following cases:
•When there is equipment or a device
near the vehicle using the same radio
frequency as that of the tyre pressure
sensors.
•When a metallic device such as a
non-genuine navigation system is
equipped near the centre of the
instrument panel, which may block
radio signals from the tyre pressure
sensor to the receiver unit.
•When using the following devices in the
vehicle that may cause radio
interference with the receiver unit.
•A digital device such as a personal
computer.
•A current converter device such as a
DC-AC converter.
•When excess snow or ice adheres to the
vehicle, especially around the wheels.
•When the tyre pressure sensor batteries
are exhausted.
•When using a wheel with no tyre
pressure sensor installed.
•When using tyres with steel wire
reinforcement in the side walls.
•When using tyre chains.

▼Tyres and Wheels
CAUTION
When inspecting or adjusting the tyre air
pressures, do not apply excessive force to
the stem part of the wheel unit. The stem
part could be damaged.
Changing tyres and wheels
The following procedure allows the TPMS
to recognise a tyre pressure sensor's
unique ID signal code whenever tyres or
wheels are changed, such as changing to
and from winter tyres.
NOTE
Each tyre pressure sensor has a unique ID
signal code. The signal code must be
registered with the TPMS before it can
work. The easiest way to do it is to have
an Authorised Mazda Dealer change your
tyre and complete ID signal code
registration.
When having tyres changed at an
Authorised Mazda Dealer
When an Authorised Mazda Dealer
changes your vehicle's tyres, they will
complete the tyre pressure sensor ID
signal code registration.

When changing
tyres yourself
If you or someone else changes tyres, you
or someone else can also undertake the
steps for the TPMS t o complete the ID
signal code registration.
1. After tyres have been changed, switch
the ignition ON, then back to ACC or
OFF.
2. Wait for about 15 minutes.
3. After about 15 minutes, drive the vehicle at a speed of at least 25 km/h
(16 mph) for 10 minutes and the tyre
pressure sensor ID s ignal code will be
registered automatically.
NOTE
If the vehicle is driven within about 15
minutes of changing tyres, the tyre
pressure monitoring system warning light
will flash because the sensor ID signal
code would not have been registered. If
this happens, park the vehicle for about 15
minutes, after which the sensor ID signal
code will register upon driving the vehicle
for 10 minutes.
Replacing tyres and wheels
CAUTION
 When replacing/repairing the tyres or
wheels or both, have the work done by
an Authorised Mazda Dealer, or the tyre
pressure sensors may be damaged.
 The wheels equipped on your Mazda are
specially designed for installation of the
tyre pressure sensors. Do not use
non-genuine wheels, otherwise it may
not be possible to install the tyre pressure
sensors.
Be sure to have the ty re pressure sensors
installed whenever tyres or wheels are
replaced.
When having a tyre or wheel or both
replaced, the follow ing types of tyre
pressure sensor installations are possible.
•The tyre pressure sensor is removed
from the old wheel and installed to the
new one.

•The same tyre pressure sensor is used
with the same wheel. Only the tyre is
replaced.
•A new tyre pressure s ensor is installed
to a new wheel.
NOTE
•The tyre pressure sensor ID signal code
must be registered when a new tyre
pressure sensor is purchased. For
purchase of a tyre pressure sensor and
registration of the tyre pressure sensor
ID signal code, consult an Authorised
Mazda Dealer.
•When reinstalling a previously removed
tyre pressure sensor to a wheel, replace
the grommet (seal between valve body/
sensor and wheel) for the tyre pressure
sensor.

Do not rely completely on the parking sensor system and be sure to confirm the safety around
your vehicle visually when driving.
This system can assist the driver in operat ing the vehicle in the forward and backward
directions while parking. The detection ranges of the sensors are limited, therefore, driving the
vehicle while relying only on the system may cause an accident. Always confirm the safety
around your vehicle visually when driving.
NOTE
•Do not install any accessories within the detection ranges of the sensors. It may affect the
system operation.
•Depending on the type of obstruction and the surrounding conditions, the detection range
of a sensor may narrow, or the sensors may not be able to detect obstructions.
•The system may not operate normally under the following conditions:
•Mud, ice, or snow is adhering to the sensor area (Returns to normal operation when
removed).
•The sensor area is frozen (Returns to normal operation when the ice is thawed).
•The sensor is covered by a hand.
•The sensor is excessively shocked.
•The vehicle is excessively tilted.
