Warning/Indicator Lights and Warning Sounds
Signal
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
Tire
speeds, or perform sudden maneuvering
Pressure
or braking. Vehicle drivability could worsen

and result in an accident.
System
To determine if you have a slow leak or a
Warning
fl at, pull over to a safe position where you

Light
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.

Warning Action to be taken
Inspect the tires and adjust to the specifi ed
infl ation pressure (page 6-42 ).
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 infl ation pressure, the TPMS warning
light/beep may turn on after the tires cool and
pressure drops below specifi 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.
Tires lose air naturally over time and the TPMS
cannot tell if the tires are getting too soft over
time or you have a fl at. However, when you
fi 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 reinfl ating
the tire as leaks are dangerous — take it to an
Authorized Mazda Dealer.
Verify the reason why the warning light is
illuminated on the center display (page 7-24 ).
If the reason why the warning light is
illuminated is due to a dirty windshield, clean
the windshield.
If the warning light is illuminated because of a
dirty radar sensor, clean the front emblem.
For any other reasons, have the vehicle
inspected at an Authorized Mazda Dealer.
