TPMS sensor relearn

[Rally Sport]

Does the 2008 Buick Lacrosse cx have a TPMS reset button and if it does where is it located?

It's covered on page 5-74 of owners manual and is not just pushing a button

The only time you should need to 'relearn' the TPMS is when a tire rotation is done and every dealer/tire center is supposed to do that. They often miss that part of the process. But you can also buy a cheap relearn tool, as I did. It worked on my 2013 Cadillac ATS and also works on my 2018 Buick Lacrosse. Read your manual to learn how to relearn using this tool.

To clarify, if the tires are simply rotated, without removal of the valve stems, then a relearn shouldn't even be necessary since the car will recognize and follow each tire's location whichever position it is moved to. I also bought a GM-specific relearn tool just in case - was only about $11 on Amazon when I bought it a few years ago.
