Power Lumbar
If your vehicle has this
feature, the power lumbar
control is located on
the outboard side of each
front seat. Use the
power seat control first to
get the proper position.
Then continue with
the lumbar adjustment.
To reshape the lower seatback, press the lumbar
control forward to increase support and rearward to
decrease support. Press the control up or down to raise
or lower the support mechanism.
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.
If you have the independent front cushion moved down
as far as it will go, you may feel the lumbar support
higher in your back. Readjust the location of the cushion
until you are comfortable. You may also want to
adjust the seatback for maximum comfort.
Heated Seats
If your vehicle has this
option, the heated front
seat controls are located
on the instrument
panel under the climate
controls.
Push ON once for the HI setting or twice for the LO
setting. The lights above the button will come on
to indicate which setting has been activated. Push OFF
to turn the heated seat off. The LO setting warms
the seatback and cushion until the seat approximates
body temperature. The
HI
setting heats the seatback
and cushion to a slightly higher temperature.
The heated seats can only be used when the ignition is
turned on. The heating elements in the seats
automatically turn off when the vehicle's ignition is
turned off.
