    Anyone able to identify these switches? Have had the car for several years and never noticed them before.

    PCS on/off turns on "Pre-collision system". It applies the brakes if it thinks you are about to crash. Can be tripped by bridge expansion joints, as per the owners manual. If off, a yellow "PCS" appears in the right upper part of the instrument panel.

    The "SET" one has a tyre beside the word, meaning it's the tire pressure warning system pressure setting. Hold it till it beeps (after you have set the pressure in all four tyres to what you think they should be). It will warn you if the pressure in any of the four tyres drops 20%.

    The toggle switch is "aftermarket" home brew. You'll have to trace it to figure out what it does. Or ask the people you bought the car from.

    Did you get a manual? If not, they are available for download on the Toyota website.

    Manual describes the functions but not seeing a reference to these switches. Yes, that one on/off switch looks like a home brew solution but not yet sure where it leads. THANK YOU for the info on the PCS too!

    maybe alarm? the oem switches should be in the cockpit diagrams in the beginning of the manual.
