Driving Your Mazda
Warning/Indicator Lights and Beep Sounds
NOTE
Perform tire pressure adjustment when the
l
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, may turn
off 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.
After adjusting the tire air pressures, it may
l
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
l
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 refilling the
trouble tire as leaks are dangerous - take it
to an Authorized Mazda Dealer which has
all the equipment to fix tires, TPMS systems
and order the best replacement tire for your
vehicle.

If the warning light illuminates again even
after the tire pressures are adjusted, there
may be a tire puncture. Replace the
punctured tire with the temporary spare
tire (page 7-8).
NOTE
A tire pressure sensor is not installed to the
temporary spare tire. The warning light will
flash continuously while the temporary spare
tire is being used.
Warning light flashes
When the warning light flashes, there may
be a system malfunction. Consult an
Authorized Mazda Dealer.
