When the warning light illuminates, and the
warning beep sound is heard when tire pres-
sure 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 maneu‐
vering 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 moni‐
tored 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 be‐
fore 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 in-
flation pressure (page 6-39).

CAUTION

When replacing/repairing the tires or wheels or
both, have the work done by an Authorized
Mazda Dealer, or the tire pressure sensors may
be damaged.

NOTE



Perform tire pressure adjustment when the tires are
cold. Tire pressure will vary according to the tire tem-
perature, 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 pres-
sure drops below specification.
Also, an illuminated TPMS warning light, resulting
from the tire air pressure dropping due to cold ambi-
ent temperature, may turn off if the ambient tempera-
ture rises. In this case, it will also be necessary to ad-
just 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.



After adjusting the tire air pressures, it may require
some time for the TPMS warning light to turn off. If
the TPMS warning light remains illuminated, drive
the vehicle at a speed of at least 25 km/h (16 mph) for
10 minutes, and then verify that it turns off.



Tires lose air naturally over time and the TPMS can-
not 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 refilling the trouble tire as leaks are
dangerous 

―

 take it to an Authorized Mazda Dealer

which has all the equipment to fix tires, TPMS sys-
tems and order the best replacement tire for your ve-
hicle.

If the warning light illuminates again even after the
tire pressures are adjusted, there may be a tire punc-
ture.
