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.

(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.
