If Trouble Arises
Warning/Indicator Lights and Warning Sounds
Vehicle with run-fl at tyres
Warning Action to be taken
When the warning light illuminates, and the warning
beep sound is heard when tyre pressure is too low in
one or more tyres.
WARNING
If the tyre pressure monitoring system warning
light illuminates or fl ashes, or the tyre pressure
warning beep sound is heard, decrease vehicle
speed immediately and avoid sudden manoeuvring
and braking:
If the tyre pressure monitoring system warning
light illuminates or fl ashes, or the tyre pressure
warning beep sound is heard, it is dangerous to
drive the vehicle at high speeds, or perform sudden
manoeuvring 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 tyre and determine if you
have enough air to proceed to a place where air
may be added and the system monitored again by
an expert repairer, we recommend an Authorised
Mazda Repairer or a tyre 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 tyre failure and a dangerous accident.
Inspect the tyres and adjust to the specifi ed infl ation
pressure (page 6-36 ).
CAUTION
When replacing/repairing the tyres or wheels or
both, have the work done by an Authorised Mazda
Repairer, or the tyre pressure sensors may be
damaged.
NOTE
Perform tyre pressure adjustment when the tyres are cold.
Tyre pressure will vary according to the tyre temperature,
therefore let the vehicle stand for 1 hour or only drive it
1.6 km (1 mile) or less before adjusting the tyre pressures.
When pressure is adjusted on hot tyres to the cold infl ation
pressure, the TPMS warning light/beep may turn on after
the tyres cool and pressure drops below specifi cation.
Also, an illuminated TPMS warning light, resulting
from the tyre 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 tyre air
pressures. If the TPMS warning light illuminates due to a
drop in tyre air pressure, make sure to check and adjust the
tyre air pressures.
After adjusting the tyre 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.
Tyres lose air naturally over time and the TPMS cannot tell
if the tyres are getting too soft over time or you have a fl at.
However, when you fi nd one low tyre 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
tyre 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 refi lling the trouble tyre
as leaks are dangerous — take it to an expert repairer, we
recommend an Authorised Mazda Repairer which has all
the equipment to fi x tyres, TPMS systems and order the
best replacement tyre for your vehicle.
If the warning light illuminates again even after the tyre
pressures are adjusted, there may be a tyre puncture.
