Has anyone noticed two buttons under the steering wheel on their RX330? One says set and the other I forgot. What do they do?

 

on page viii of your manual, there is a labelled diagram of the instrument panel with the page number where you can read all about that switch function. I didnt realize we had all these extra switches, like traction control (on/off), height control and a few others. No wonder why the manual is so thick.

 

No, its UNDER the steering wheel, about 4 inches to the right of the OBD-II connector.

 

I believe that is the set/program button for the tire pressure sensors and the other is the on/off dor the traction control.
