Title says it all, left of steering wheel where traction control button is, I have an extra space for a button. What was supposed to go there? Anyone have all three filled?
2013 RDX AWD Tech

 

Honda uses the same buttons in all of their line up.
Copy, paste. Copy, paste. Copy, Paste.

one of their models use an extra button.
and instead of deleting it, they just put a empty do-nothing button, place holder

 

I wish it was for passenger ejection seat.

 

On the '16, there are two gangs of two buttons in that location. They are:

Vehicle Stability Assist (VSA) OFF
Lane Departure Warning (LDW)
Collision Mitigation Braking System (CMBS) OFF
Parking Sensor system
