Signal Warning Action to be taken
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
in À ation pressure (page 6-43 ).
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 in À 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 rein À ating
the tire as leaks are dangerous — take it to
an Authorized Mazda Dealer.
