GM Chevrolet Avalanche - Manual (Page 11)

The low setting warms the seatback and cushion until
the seat temperature is near body temperature. The
medium and high settings heat the seatback and seat
cushion to a slightly higher temperature. You will be able
to feel heat in about two minutes.
To heat only the seatback, press the vertical button with
the heated seatback symbol. An indicator light on the
seatback button will glow to designate that only the
seatback is being heated. Additional presses of
the seatback button will cycle through the heat levels for
the seatback only. Press the horizontal button again
to heat the whole seat.
The heated front seats will shut off automatically when
the ignition is turned off.
Reclining Seatbacks
If you have manual reclining seatbacks, the lever is
located on the outboard side of the seat cushion.
To adjust the front seatback, lift the lever. Release the
lever to lock the seatback where you want it. Lift
the lever without pushing on the seatback and the
seatback will go to an upright position.
If your vehicle has power seats with a power recliner,
see Power Seats on page 1-2 for further information on
how to operate the reclining seatback feature.
