lumbar support GMC SIERRA CLASSIC 2007 Owners Manual

Power Lumbar
Your vehicle may have this feature.
The control is located
on the outboard side of
the seat cushion.
To increase or decrease support, hold the control
forward or rearward. Keep in mind that as your
seating position changes, as it may during
long trips, so should the position of your lumbar
support. Adjust the seat as needed.
Heated Seats
If your vehicle has this
feature, the buttons are
located on the front
doors. The engine must
be running for the
heated seats to work.
To heat the entire seat, press the horizontal button
with the heated seat and seatback symbol.
Press the button to cycle through the temperature
settings of high, medium and low and to turn
the heated seat off. Indicator lights will come on to
designate the level of heat selected: three for
high, two for medium, and one for low.
