The Tire Pressure Monitoring System, or TPMS, uses pressure sensors and transmitters in each mounted wheel to alert you when the air pressure in one or more of your tires is critically low.
If the system detects low air pressure, the TPMS icon will appear in the instrument display and stay on. If the indicator comes on, check all four mounted tires and refill or replace the low tire or tires. After rotating tires, changing tire inflation pressures, loading heavy cargo or changing tire sizes, you may need to reinitialize the system.
- Begin by parking the vehicle in a safe place, setting the parking brake and switching the ignition off.
- Make sure all tire pressures are correct according to the owner’s manual.
- Put your foot on the brake and press the power button to turn the system on.
- Press and hold the TPMS reset button located below the steering wheel until the TPMS indicator light flashes slowly three times.
- Wait for a few minutes and then turn the vehicle off.
- If the light comes on, blinks for one minute, then stays on, it indicates the system isn’t working properly and needs to be serviced by a trained Toyota technician.
Where is the Tpms button? Would help if you showed a visual of that
The TPMS reset button for Prius is located right under the steering wheel column, as shown in this picture.
