2018 Lumbar support?

Miguel Olea · July 4, 2020

I could have sworn my 2018 SLT had dual lumbar adjustments for the back and and seat pad just like my 2006 Yukon. However, today I went to adjust it and realized I only have lumbar adjustments for the back and not the seat cushion. Is this right?

Correct:

Power Lumbar
To adjust the power lumbar support, if equipped: . Press and hold the control forward to increase or rearward to decrease upper and lower lumbar support at the same time. . If equipped, press and hold the control up to increase upper lumbar support and decrease lower lumbar support. Press and hold the control down to increase lower lumbar support and decrease upper lumbar support.

In the OM picture, they are only showing the back of the seat.

so it sounds like it is indeed an option. I thought my SLT with memory seats and heated and cooled would have this. Guess I got gypped.

Don't think it was an option at all with the K2's.

But, let me go check my seat.

Lumbar adjustments are only for the lower back, the seat is where your ass goes. I dont beieve they make butt curvature adjustments yet.

Thanks. Yah, my 06 Yukon has it on the lower seat cushion also. It's kind of neat. It brings the edges of the seat closer to your hips. I guess they call it lower thigh support? Here is an explanation from the 06 manual Thanks for the replies.
