If it does, no big deal, right?
Just have the tire shop mount the tires and install?
Car will sync with some touching of the infotainment screen? (I will do some manual reading.)

I've got some Michelin X-Ice's ordered in original size.

If they don't come with TPMS, there'll be the Sturm Und Drang of Toyota vs Amazon, frequency, risks, etc, etc.

I've been looking for steps for getting to the battery and taking the battery apart - but I haven't found anything.

I'm also pretty concerned about the HV. But I'd rather do the work myself.]]> 3 Sat, 14 Feb 2026 02:44:09 +0000 https://priuschat.com/threads/spare.258993/ https://priuschat.com/threads/spare.258993/ invalid@example.com (Milas 13) Milas 13 1 Thu, 12 Feb 2026 14:01:33 +0000 https://priuschat.com/threads/23-le-front-bumper-repair.258702/ https://priuschat.com/threads/23-le-front-bumper-repair.258702/ invalid@example.com (Brian5673) Brian5673 3 Thu, 05 Feb 2026 18:12:42 +0000 https://priuschat.com/threads/snow-tires-for-a-2026-xle-and-17-wheel-size.257903/ https://priuschat.com/threads/snow-tires-for-a-2026-xle-and-17-wheel-size.257903/ invalid@example.com (blfuller) blfuller 49 Wed, 04 Feb 2026 21:59:22 +0000 https://priuschat.com/threads/obtaining-inverter-coolant-temperature-via-obd.258888/ https://priuschat.com/threads/obtaining-inverter-coolant-temperature-via-obd.258888/ invalid@example.com (PrimeDan) PrimeDan
I've tried using both OBD Fusion and Car Scanner with a Bluetooth dongle to no avail. I've attached screenshots of all the temperature readings, but nothing related to the inverter is showing. As you can see, I've correctly selected the Prius Prime profile as well, so I'm not sure what else to try.

I'm stumped!

Although the 26 engine verbage in the manual clearly states 016w may be used for one cycle and then immediately go back to 0w8 consistently.

Strange. Seems to be begging for a larger issue, even if possibly only technical.

Apparently the same engine on non north American sold vehicles with this engine, Prius 5th gen.. always...

"If you don't use any remote services then I suggest googling how to disable the DCM/Telematics unit in the car.

The tacoma forums have good info. I've found that the Prius people are pretty complacent regarding the matter and don't seem to care much.

You'll need to bridge some pins to restore door speaker and microphone (the microphone requires power supplied through the telematics unit to function).

That is if you're...

Next week tire shop is going to put new winter tires on the rims and I asked them to install the TPMS sensors I bought. They want $25 per tire just for programming! I know there is an option in the car menu to add different wheels etc. Do I need to have these programmed of can I just go thru that menu to add these TPMS to the car?]]> 61 Thu, 18 Dec 2025 15:38:31 +0000 https://priuschat.com/threads/teardown-of-a-5th-generation-prius-inverter.258266/ https://priuschat.com/threads/teardown-of-a-5th-generation-prius-inverter.258266/ invalid@example.com (notspam3) notspam3
