(Turns on)
Tire Pressure Monitoring
System Warning Light
*
When the warning light illuminates, and
the warning beep sound is heard when 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
fi
ed
in
fl
ation 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
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
fl
ation
pressure, the TPMS warning light/beep may turn
on after the tires cool and pressure drops below
speci
fi
cation.
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 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
cannot tell if the tires are getting too soft over time
or you have a
fl
at. However, when you
fi
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 re
fi
lling
the trouble tire as leaks are dangerous — take it
to an Authorized Mazda Dealer which has all the
equipment to
fi
x 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.
