Reset Tire Pressure Warning Light

[DED NoNev]

On our 2025 Subaru Outback the tire warning light came on. I added air where necessary to get the proper tire pressure but the warning light remains on. The Yellow !. I cannot find a way to make it go off. The warning just wants me to go to the dealer who is 45 miles away. I cannot find in the manuals how to reset the warning. I made sure it is set to PSI.

Drive the car for about a mile and it should reset. This is in also in the manual under tires/warning light.

The TPS sensors do not turn on until the tires have been in motion for a mile or so. If they didn't do that the batteries would die in short order. Fill the tires to recommend pressure then go drive the car a mile or two and they should go off. If not it's probably a dead battery in a wheel sensor. If that's the case, I'd have a tire shop replace all the tire sensors.

Subarus (at least through 2024 - the last year I checked) have only four memory slots for the TPMS IDs, so when you switch to snow tires, you have to reprogram the system to recognize the tires. I bought an Autel unit to both check the tire pressure (it reads the TPMS from each tire) and reprogram the car. If you have to take it to the dealer, it's $$. My F150 has eight slots, so swapping snows needs no extra work.

I think if i were you i will buy a codes reader to check if any issues with your tires i bought a XTOOL D5S compatible with the Subaru vehicle it help me to check to my Outback 2020 if i don't have any issues with codes i got an issues
my with my wife's car a Honda Civic and i check it because she as a warning Engine light was on i check for codes it gave me some codes
that i print it out and bring to the Honda dealer guess what the dealer got the same code. these day some dealers will try to trick you with something else to make $$$ than we gave the code to them and they said they have the same codes issues or issues was the gasoline cap wasn't close correctly and let air getting in the system and make the yellow engine light come on and we have to replaced a device to the system. by the way the device will show you all codes issues if they are present you will know in advance before you go to the dealer.

Doubt the Subie system actually has batteries, but there is a question how the sensors talk to the unit. Our first car with TPMS sensed pressure by, essentially, measuring tire diameter (less air/smaller diameter). Installing winters, on rims, didn't require any re-set.
The current system, in the Beemers, demands a re-set when I install the winter tires, and the sensors sometimes change with a new model year....kept the winters that had been on our old car, and it required new ones.
So the Outback is a mystery; the dealer rotated the tires at a recent service, using the spare in the rotation...I did have to drive a mile or two before the sensors resumed working.

They do indeed have a battery powered sender unit in each wheel. Otherwise, how do you think it works? They activate after the wheel has spun for while otherwise the batteries would die much much sooner than they do. The good news is that it isn't necessary for the car to run and you can just forget all about it. After all we all drove around with out TPMS, happy as pigs in mud long before TPMS was crammed down all of our throats.

I'm old fashioned enough to check mine once a month, and to compensate for temperature change. For awhile, we didn't bother with the sensors for the winter rims, and just let the light on all winter.
But TPMS is a handy backup, and I'll check it pretty often when driving. The reported temps don't always correspond to what the handheld gauge found. The Beemer's system tells you tire temperature as well.

The TPMS system was designed with my wife in mind. Bless her, she drove five-miles from downtown to home on a flat tire. Destroyed the Subaru rim that left a continuous gouge in the street and all the way into my garage. The tire was barely intact. True story!
