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 maneuver‐
ing 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 sud‐
den 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 acci‐
dent.

Inspect the tires and adjust to the specified in-
flation pressure (page 6-38).

NOTE



Perform tire pressure adjustment when the
tires are cold. Tire pressure will vary accord-
ing to the tire temperature, therefore let the ve-
hicle stand for 1 hour or only drive it 1.6 km (1
mile) or less before adjusting the tire pres-
sures. 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, re-
sulting from the tire air pressure dropping due
to cold ambient temperature will remain illu-
minated 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 pres-
sure, 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 side-
wall. 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 sim-
ply reinflating the tire as leaks are dangerous
