Toyota RSCA Button

My 2016 LC has a button that many Toyotas now have.  It's labeled "RSCA OFF".  My drive on the 4wd trails around the cinder cones last week was the first time that I've used that button.

RSCA means Rollover Side Curtain Airbag.  These aribags are activated by some inclinometer in the vehicle.  If it detects that the truck has tipped over too far (e.g., a rollover), then they are inflated.

Toyota provides the button so that this system can be intentionally deactivated by the driver when driving in "extreme off road" conditions.  Here's a screencap from the 2016 LC manual.


This prevents the system from activating simply because the truck is tipped over a lot in pitch or roll.  During my drive in the desert, my truck was tilted a lot.  Not as much as I've done in the past in a Land Rover.  But I didn't want to take any chances.

Maybe RSCA means Roll Sensing Curtain Airbag?
I honestly don't know.
