I needed a refresher on how to better use/disable traction control.
TL;DR - At a stop
Been playing in the dirt with 37s and one thing that stands out is when the wheel/tire package deviates so much from stock, traction control can be an annoyance. No surprise as as the stability control is always monitoring vehicle response and with mods, it reacts differently. Things like smaller wheel sizes with more tire sidewall and overall compliance, larger overall tire sizes, suspension geometry, narrow tire fitments, even airing down too far can trip stability control prematurely.
I find that running larger rim sizes and/or using higher inflation pressures can help as they tighten up vehicle response closer to stock even with running large 35s. Using full fat tires help handling traction stay closer to stock with AT tires. Now that I'm down to 18s, and going to 37s, things like even turning right to merge can trip the system.
Note that this assume good zero point calibration, which everyone should do anytime there's alignment or suspension changes.

Going back to the manual, there's really two modes to turning off stability control. There's also multiple traction aids at play including Active TRAC, VSC, Trailer Sway Control, hill-0start assist.
I don't know that this is the exact same behavior for all model years and the LC. I assume it is or very close.

TL;DR - At a stop
- Short press of Trac Off button temporarily turns off Active Trac systems. It will re-enable automatically when speed increases (~40mph)
- Long 3 second press of the Trac Off button turns off Active Trac, VSC, and trailer Sway Control. It will not automatically re-enable.

Zero Point Calibration
It's not talked about on this site, but it's a thing in almost all Toyota/Lexus models - zero point calibration. I have not researched this topic enough to understand it fully, but it's generally recommended after any sort of suspension, alignment, steering rack work, that a zero point...
