Tire Pressure Warning Reset Switch
2010 Toyota Matrix AWD L4-2.4L (2AZ-FE)SECTION Tire Pressure Warning Reset Switch
TIRE PRESSURE WARNING RESET SWITCH
*By operating the tire pressure warning reset switch, the tire pressure warning ECU can be set to issue a warning at an inflation pressure that corresponds to the standard pressure of the tires fitted to the vehicle.
*Therefore, the warning threshold must be set to the proper value using the Techstream in order to comply with local regulations.
*Operate the tire pressure warning reset switch only after the inflation pressures of all tires have been adjusted on the vehicle.
*To initialize the system, press and hold the tire pressure warning reset switch for 3 seconds or longer with the ignition switch ON. When the system receives the initialization signal, the warning light blinks 3 times (1 second on, 1 second off).
*During initialization, the tire pressure warning valve and transmitter measures the inflation pressure of the tire, and registers the signals that are transmitted into the tire pressure warning ECU at a frequency of once per minute. The initialization process is completed after signals from all the tires have been received. It may take about 2 or 3 minutes until the values are displayed.

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
