Using Tire Pressure Monitoring System Set Switch

WARNING: This page is about a different car, the 2017 Mazda 3. However, it is still accessible from the selected car via links, so may be relevant.

Park the vehicle on safe, level ground.
Adjust all four tire pressures to the specification while the tires are cold. (See WHEEL AND TIRE SPECIFICATION .)
CAUTION:
- Cold tires means leaving the vehicle for 1 h or, if the vehicle is driven, do so within 1.6 km {0.99 mile}.
Switch the ignition ON (engine off or on).
Press and hold the tire pressure monitoring system set switch.
