Warning
When the warning light illuminates, and
the warning beep sound is heard (about 3
seconds), 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.
Action to be taken
Inspect the tyres and adjust to the specifi ed
infl ation pressure (page 6-40 ).
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 will remain illuminated
even 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.
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 reinfl ating the tyre as leaks
are dangerous — take it to an expert
repairer, we recommend an Authorised
Mazda Repairer.
