If Trouble Arises
Warning/Indicator Lights and Warning Sounds
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 flashes, 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 flashes, 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 flat, 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 specified inflation pressure (page 6-42).
NOTE
Perform tyre pressure adjustment when the tyres are cold. Tyre pressure will vary according to the tyre tem‐
perature, 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 inflation pressure, the TPMS warning light/
beep may turn on after the tyres cool and pressure drops below specification.
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 neces‐
sary 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 flat. However, when you find 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 reinflating the tyre as leaks are dangerous ―
take it to an expert repairer (we recommend an Authorised Mazda Repairer).
