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.
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.
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 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.
Tyre Pressure Monitoring System
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 sidewalls.
When using tyre chains.
