Default Two buttons that most LS owners might not know about

Two buttons that probably most LS owners don't know about (I have owned one 2007 LS 460l and three ls 600HLs and I have never heard of these two buttons)....

1. PCS on/off.
2. There TPMS button right next to the preceding button.

These two buttons are just above the accelerator pedal. If you lean into the well, you will see them side by side.

Wow I'll have to go and take a look when I get home. The TPMS one sounds interesting.

But come to think of it, I think I recall vaguely that my prior LS models (pre 2007, which had tpms but not the pressure reading - just a light) also had tpms off button in the same location. I am not sure.. may be I just forgot about it..

1. TPMS on/off. I actually need this because I don't want to spend $228 for 3 months that I put snow tires on. My dealer charges me $114 to program tmps of my snow tires and another $114 to program the summer tires back in spring.
2. There is a reset button right next to the preceding button. This resets the PCS malfunction light. It worked for me.

These two buttons are just above the accelerator pedal. If you lean into the well, you will see them side by side.
I can't speak to what is on the LS600 but the LS460s don't have a TPMS On/Off switch. And they don't have a TPMS Reset switch. They have a TPMS Set switch. The Set switch is used to set the low pressure warning thresholds in the car's electronics. Injudicious operation of the Set switch can compromise the safety features provided by the TPMS and cause nuisance false alarms.

I stand corrected. I guess the ls460 didn't have a tpms off switch. Anyway, the two switches on the ls600hl are in the same location as in your pictures.

Cant help notice that just to the left of the TMPS button, theres a blank tap. Might be a possible location for on/off on the 600.

You need a picture? Its easy to see, if you have the car.. The picture of the ls 430 actually pretty much shows it.. its the same on the 460 also.

The TPMS is a NHTSA mandated safety system on all cars sold in the US beginning in 2008. I believe that it is illegal to do anything to disable it. There probably is no personal legal jeapordy for disabling it but a functioning TPMS is probably required or will be required for state safety inspections.

Hey, guess I lucked out for once. My dealer only charges $58 to swap the four mounted tires and reset the TPMS codes.

I had an '06 GS430 that had a switch above the passenger foot well that would remember two different TPMS codes, sure was nice.

I want a picture of your car buttons. I have an 460L that's loaded but I don't have the buttons that you mention.

With about 99% certainty. .you have the same buttons as the pics above. Just reach down under your dash just above accelerator. .I promise you they are there. I think those who have the little box of infrared leds on the steering column for advanced pcs will have that pcs button in that dummy panel..I think when our radar cruise is working is when our pcs system works
