How To Use GMC Seat Massage, Lumbar, Shoulder, And Bolster Support On GMC's 

Hopefully one day I’ll need your tutorial 😂

Very helpful and just the detailed info I needed. TY!

Way to go man! Thank you

It's pretty bad when you have to watch a video to learn about things that should be covered in the owner's manual .

Whats the button do?

Anyone else have a problem with the lumbar and bolster settings not saving? My lumbar inflates fully every time I get in the truck.

Is this option only in the denali ultimate?

Is this come be available on suburban high country 2025?

So you cant use it just from the infotainment center

2024 3500 ultimate, no bottom massage . Seats are uncomfortably . Should have kept my superduty , much more comfortable on trips .

I had a hard time adjusting it. It is not the best designed system.

HATE IT PERIOD. TERRIBLE TRYING TO FIGURE THAT FUNCTION!!!

Wow this is for spoiled people xD 😂
