designate the level of heat selected: three for high, two
for medium and one for low. 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 button with the
words BACK ONLY. An indicator light on the switch will

power seat control described earlier allows the seatback
to recline.
