Vehicle with run-À 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 À 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 À 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 À 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 speci¿ ed inÀ ation
pressure (page 6-34 ).
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 inÀ ation pressure,
the TPMS warning light/beep may turn on after the
tyres cool and pressure drops below speci¿ 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 À at. However, when you ¿ 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 re¿ 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 ¿ 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.
