Inspect the tyres and adjust to the specified inflation pressure (page 6-47).
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 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, 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 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 refilling 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
fix 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.
