The little red pieces you see sit between the circuit board and the button to negate being able to push it depending on the function you have. Pop off the button corresponding to the feature, remove the red pieces, and you'll be good to go.
Well thank you for the info that really helps. So I can buy the switch with the heated seats, front PDC and rear shade and I can transfer the Hill Assist from my current one and I would have everything working. The only thing is the Hill Assist has an LED light above the button.
Thanks again for sharing
