Just bought a 2016 GS 350 with 32k miles on it and would like to see what the smog level sensor is set at.Can not find it in the manual.
Any help will be much appreciated. Thanks.
I’m curious to see if this makes a difference for you. In my first GS (2013) it seemed like my car would switch to recirc very quickly if anything smelled bad outside. In my new GS (2017) it seems to switch much later, if at all. I have the sensor set in the infotainment menus to be as sensitive as possible, and I also took it out and cleaned it.

I set mine at number 2 on the least sensitive and it switches over pretty often.
