Tire Pressure Monitoring
System (TPMS)

Tire Pressure Monitoring System
(TPMS)
The TPMS monitors the air pressure of
each tire and if it decreases below the
specified value, the system notifies the
driver by turning on the TPMS warning
light in the instrument cluster and
indicating a message on the
multi-information display.
For the TPMS, the air pressure data sent
from the tire pressure sensors installed on
each wheel via radio signal is received by
the receiver unit in the vehicle to monitor
the tire pressures.
1. Tire pressure sensors
In addition, the current tire pressures can
be checked using the center display.
Refer to the Information section in the
Mazda Connect Owner's Manual.
NOTE

When the ambient temperature is low,
the tire temperatures also decrease. If
the tire temperatures decrease, the air
pressure in the tires will also decrease
which could turn on the TPMS warning
light.

Before driving, visually inspect the tires
for abnormalities. Additionally, inspect
the tire pressures monthly. A digital type
air pressure gauge is recommended for
inspecting the tire pressures.
The TPMS is not a substitute for your own
periodic inspection of the tires. Always
inspect the tires yourself periodically.
CAUTION

Each tire, 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
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.)
As an added safety feature, your vehicle
has been equipped with a tire pressure
monitoring system (TPMS) that
illuminates a low tire pressure telltale
when one or more of your tires is
significantly under-inflated. Accordingly,
when the 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-inflated tire causes
the tire to overheat and can lead to tire
failure. Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
