If re-initializing the TPMS was not needed to allow the system to properly recognize the tire orientation, why would the manual say that the system needs to be re-initialized after the tires are rotated?
I think you're right.. we have yet to hear that someone has gotten false information after the rotation as to the wrong tire being reported when they checked and filled.

As I said earlier, I think that could be the result of the fact that tire dealers, Lexus dealers, etc. are making it a part of their normal practice to re-initialize the TPMS as a part of what they do when they do a rotation.

After I read the post about reinitializing the sensors, I remembered that I rotated my tires but never reset them. I went and looked for the button "under the dash"... I couldn't find it! I then went into my 2013 owner's manual and it showed it as under the dash on the left of the wheel. No button...

The button is there, but it is very hard to find.
It is under the dash just a bit to the left of the steering wheel. To find it, you can either get down on your knees on the ground next to the open driver's door and stick your head up under the dash to look for it, or you can take a flash light and a mirror pointed under that part of the dash. Without being able to see it either directly or with a mirror, it is unlikely that you will find it by "feel".

OK thanks. I'll go out and try again with my wife's mirror...
Found it with a mirror and two sore knees... Thanks Les and Gamma...
The first time that I looked for and found it, I used the contortionist method and twisted my body like a pretzel to look under the dash. The result was the sore knees and a sore back.
Wow, I didn't know that programming the tire sensors were that involved and required the dealer or via Techstream. When I was at Costco inquiring about new tires with TPMS, they seem to deal with this all day long and NBD. Maybe I'm a bit naive here.
Or if you have a TPMS tool( I have one from Autel) you can do whatever you want. In my case I have two sets of tires/rims/TPMS I change them myself. With tool I scan 4 TPMS, in this order, LF >> RF >> RR >> LR and connect the tool to OBD II port under dash, register them by just pushing a button. I repeat when I changed tires/rims set for the season. Takes maybe 10 mins.

That must be what the Tire Shops are using.
Does pushing the button while having the TPMS tool (one from Autel) plugged into the OBD2 post, upload the TPMS IDs to the car?

Little more for head up. Actually the tool is TPMS id. scanner and reader giving a reading of id. pressure, used frequency, battery voltage and temperature.
As you trigger the sensors and read id. they're sored in the scatch pad memory of the tool. When you connect the tool to the OBD II port it asks if I want
to register the TPMS ids. in the memory into TPMS memory in the ECU, then just push the button on the tool for Yes. This is how it works. It is also good for trouble
shooting TPMS issues. Tech stream can be used too but there is a time limit to manually enter new TPMS ids.(hexa-decimal numbers) into ECU. If times out,
you have to repeat the process.
