Must Lexus Adjust Tire Pressure Monitor frequently?
Just bought a new GX 470, and my salesperson, who seems to be pretty knowlegable about the car, told me that LEXUS needed to fill the tires with air in order to "register" the tire monitors properly.
I was surprised -- "You mean -- if a tire is low -- I need to bring it in to Lexus Service?!"
"Yes. Otherwise, they won't report accurately."
After reading the GX 470 Owner's Manual, it seem like Lexus absolutely didn’t care if you fill your tires yourself, and in fact, recommend you check and maintain tire pressure. No warning about Lexus Service needing to "register" or adjust each monitor.
I understand the need to "register" new tires with different batches of monitors. That makes sense.
Has anyone EVER heard this before? Is there anything about this issue (like a TSIB) from Lexus? Where could I refer this salesperson if she is misinformed?

SHE told you if a tire needs air on the GX, to bring it in to have Lexus service add air to the tire. If so, SHE is misinformed.
Wonder where I could point her to in order to get her back on track?

Misinformed isn't the word...
The TPMS sensors are "asleep" when the dealer gets them in order to save the battery. To wake them up, the dealer has to rapidly deflate each tire and then refill it to a proper pressure. That's probably what she means.
Once you drive it off the lot and the TPMS dashboard light is off, then the system is fine. The light won't come on until one of the tires drops below 27 psi or a tire disappears. Since the TPMS checks the spare as well, the light would start blinking if one of the tires was not communicating, i.e. the spare was stolen.
I've heard of Lexus dealers trying to push Lexus services, but Lexus air takes the cake!
So, yes, you can put air in yourself!

you shouldnt have to go to lexus to fill your tires with air, i know with audis all you have to do in the case your tire(s) get low is fill them up, and in the trip computer or nav system, all you do is click store tire pressures and it will save the new pressures, if you get new tires or sensors they will mostlikely have to reprogram the sensors.
