Tire Pressure Monitoring System
The Tire Pressure Monitoring System (TPMS) monitors the pressure for each tire.
If tire pressure is to o low in one or more tires, the system will inform the driver via the
warning light in the instrument cluster and by the warning beep sound.
Refer to Contact Authorized Mazda Dealer and Have Vehicle Inspected on page 7-28.
Refer to Taking Action on page 7-35.
Refer to Tire Inflation Pressu re Warning Beep on page 7-48.

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

TPMS does not alleviate your need to check the pressure and con dition of all four tires
regularly.
CAUTION
 Each tire, including the spare (if provided), should be checked monthly when cold and
inflated to the
inflation pressure recommended by the vehi
cle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle has tires of a different size than the
size indicated on the vehicle placard or tire inflation pressure label, you should determine
the proper tire inflation pressure for those tires.)

Mazda6_8JN3-EA-20H_Edition1_old 2020-6-18 17:31:27

As an added safety feature, your vehicle has been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire pre ssure telltale when one or more of your tires is
significantly under-inflated. Accordingly, when th e low tire pressure telltale illuminates, you
should stop and check your tires as soon as possible, and inflate them to the proper
pressure. Driving on a significantly under-in flated tire causes the tire to overheat and can
lead to tire failure. Under-inflation also reduce s fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire maintenance, and it is the
driver's responsibility to maintain correct ti re pressure, even if under-inflation has not
reached the level to trigger illumination of the TPMS low tire 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 tire 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 tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, including the installation of replacement
or alternate tires or wheels on the vehicle th at prevent the TPMS from functioning properly.
Always check the TPMS malfunction telltale after replacing one or more tires or wheels on
your vehicle to ensure that the replacement or alternate tires 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 tire deflation or blow out.
▼System 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
near the vehicle using the same radio
frequency as that of the tire pressure
sensors.
When a metallic device such as a
non-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 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 tire pressu re sensor batteries
are exhausted.
When using a wheel with no tire
pressure sensor installed.
When using tires with steel wire
reinforcement in the sidewalls.
When using tire chains.
