(Illuminate)
Tire Pressure Monitoring
System Warning Light *
When the warning light illuminates, and
the warning beep sound is heard (about 3
seconds), tire pressure is too low in one or
more tires.
WARNING If the tire pressure monitoring system
warning light illuminates or flashes,
or the tire pressure warning beep
sound is heard, decrease vehicle
speed immediately and avoid sudden
maneuvering and braking:
If the tire pressure monitoring system
warning light illuminates or flashes,
or the tire pressure warning beep
sound is heard, it is dangerous to
drive the vehicle at high speeds, or
perform sudden maneuvering or
braking. Vehicle drivability could
worsen and result in an accident.
To determine if you have a slow leak
or a flat, pull over to a safe position
where you can check the visual
condition of the tire and determine
if you have enough air to proceed to
a place where air may be added and
the system monitored again by an
Authorized Mazda Dealer or a tire
repair station.
Do not ignore the TPMS Warning Light:
Ignoring the TPMS warning light is
dangerous, even if you know why
it is illuminated. Have the problem
taken care of as soon as possible
before it develops into a more serious
situation that could lead to tire
failure and a dangerous accident. Inspect the tires and adjust to the specified
inflation pressure (page 6-41 ).
NOTE 
Perform tire pressure adjustment when
the tires are cold. Tire pressure will
vary according to the tire temperature,
therefore let the vehicle stand for 1
hour or only drive it 1.6 km (1 mile) or
less before adjusting the tire pressures.
When pressure is adjusted on hot tires
to the cold inflation pressure, the TPMS
warning light/beep may turn on after
the tires cool and pressure drops below
specification.
Also, an illuminated TPMS warning
light, resulting from the tire air
pressure dropping due to cold ambient
temperature will remain illuminated
even if the ambient temperature rises.
In this case, it will also be necessary to
adjust the tire air pressures. If the TPMS
warning light illuminates due to a drop
in tire air pressure, make sure to check
and adjust the tire air pressures. 
Tires lose air naturally over time and
the TPMS cannot tell if the tires are
getting too soft over time or you have
a flat. However, when you find one low
tire in a set of four-that is an indication
of trouble; you should have someone
drive the vehicle slowly forward so you
can inspect any low tire for cuts and any
metal objects sticking through tread or
sidewall. Put a few drops of water in the
valve stem to see if it bubbles indicating
a bad valve. Leaks need to be addressed
by more than simply reinflating the tire
as leaks are dangerous — take it to an
Authorized Mazda Dealer.
