Driving Your Mazda
Starting and Driving
If the warning light illuminates again even
after the tire pressures are adjusted, there
may be a tire puncture. Replace the
punctured tire with the temporary spare
tire (page 7-8).
NOTE
A tire pressure sensor is not installed to the
temporary spare tire. The warning light will
flash continuously while the temporary spare
tire is being used.
Warning light flashes
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
qSystem Error Activation
When the 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 large metallic object (e.g. a
l
large electric household appliance or a
desk-top computer) is placed on the
right side of the rear seat, 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.
5-30
When the tire pressure sensor batteries
l
are exhausted.
When using a wheel with no tire
l
pressure sensor installed.
When using tires with steel wire
l
reinforcement in the side walls.
When using tire chains.

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.
