Heated Seats
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.
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. The indicator lights above the button will
come on to designate the level of heat selected:
three for high, two for medium, and one for low.
The low setting warms the seatback and seat
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 button will come on to
designate that only the seatback is being heated.
Additional presses will cycle through the heat
levels for the seatback only.
The feature will shut off automatically when the
ignition is turned off.
