Starting and Driving
Warning light illuminates/Warning
beep sounds
If the tire pressures decrease extremely
after the TPMS warning light has
illuminated, or if a tire is punctured, the
flat tire warning light also illuminates, and
a beep sound will be heard for
approximately 30 seconds.
Refer to Vehicle with run-flat tires on
page 7-3.
qSystem Error Activation
When the TPMS warning light flashes,
there may be a system malfunction.
Consult an Authorized Mazda Dealer.
A system error activation may occur in
the following cases:
When there is equipment or a device
l
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
When a metallic device such as a non-
l
genuine navigation system is equipped
near the center of the dashboard, which
may block radio signals from the tire
pressure sensor to the receiver unit.
When using the following devices in
l
the vehicle that may cause radio
interference with the receiver unit.
A digital device such as a personal
l
computer.
A current converter device such as a
l
DC-AC converter.
When excess snow or ice adheres to
l
the vehicle, especially around the
wheels.
When the tire pressure sensor batteries
l
are exhausted.
When using a wheel with no tire
l
pressure sensor installed.

qTires and Wheels
CAUTION
When inspecting or adjusting the tire air
pressures, do not apply excessive force
to the stem part of the wheel unit. The
stem part could be damaged.
Changing tires and wheels
The following procedure allows the
TPMS to recognize a tire pressure sensor's
unique ID signal code whenever tires or
wheels are changed, such as changing to
and from winter tires.
NOTE
Each tire 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 Authorized Mazda Dealer change
your tire and complete ID signal code
registration.
When having tires changed at an
Authorized Mazda Dealer
Tire pressure sensor ID signal code
registration is completed when an
Authorized Mazda Dealer changes your
vehicle's tires.
