Tahoe Heated Seat Control Switch (What Do THOSE Buttons Do??)

[Z71Tahoe2004]

Does anyone know what the EXIT, 1, and 2 buttons on the top picture control, as opposed to the bottom picture, which doesn't have those buttons? These switches are for Tahoes up to 2002, so it looks like the top is the driver side and the bottom is the passenger side, but wondering what the extra buttons on the driver side do. Any help or insight is appreciated!

#1 #2 are for memory seat positions.
The exit should be the save memory button for the seat positions.

1 and 2 are memory seats

Exit puts the seat down and back for climbing in and out of the vehicle if you have limited mobility
