•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.

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.
