The Tire Pressure Monitoring System, or TPMS, uses pressure sensors and transmitters in each wheel to alert you when the air pressure in one or more of your tires is critically low. Space-saver spare tires are not included in the system.
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 the full-size spare, if you have one. 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.
- Turn the engine on.
- Find the TPMS reset button below and to the left of the steering wheel on the instrument panel.
- Press and hold the button until the TMPS indicator light blinks slowly three times.
- Wait for several minutes, with the engine running, and then turn the vehicle off.
If the light comes on and blinks for one minute, then stays on, it indicates the system is not working properly and needs to be serviced by a trained Toyota technician.
Don’t turn the engine on! Turn the key to the “on” position.
What if you have automatic push to start and not a key ignition?
Hey Mark. After owning my 2018 Sienna for 3 years I figured out by accident that if you are – push button start button – turn the van off – press the button once to use the radio, press it again and it is like turning the ignition to on without starting. Then you can operate the power windows or wipers without starting the van everytime while you are sitting waiting in the van sometimes. The dealers should be telling people this and I even ASKED my dealer and they didn’t know about this. One time I happened to push the start button twice without foot on the brake and it goes to the on “position”. I hope this helps.
