Manual Lumbar
Your vehicle may have this feature. This control is
located on the outboard side of the seat.
Turn the knob counterclockwise to increase lumbar
support and clockwise to decrease lumbar support.
Power Lumbar
Your vehicle may have this feature. The driver's and
passenger's seatback lumbar support can be adjusted
by moving a single control located on the outboard
side of the seat cushions. 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
To heat the entire seat, press the horizontal button with
the heated seat symbol. Press the button repeatedly
to cycle through the temperature settings of high,
medium, low and off. The indicator lights will glow to
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.
Your vehicle may have
heated front seats. The
buttons used to control this
feature are located on
the front door armrests.
The engine must be
running for the heated seat
feature to work.
