(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 fl ashes, 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 fl ashes, 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
fl at, 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
speci¿ ed inÀ ation pressure (page 6-42 ).
N O T E
y 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 inÀ ation pressure, the TPMS
warning light/beep may turn on after
the tires cool and pressure drops below
speci¿ cation.
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.
y Tires lose air naturally over time and
the TPMS cannot tell if the tires are
getting too soft over time or you have
a À at. However, when you ¿ nd 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 reinÀ ating the tire
as leaks are dangerous — take it to an
Authorized Mazda Dealer.
