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 symbol. Press the button repeatedly to cycle through the temperature settings of high, medium, low and off. The indicator lights above the button 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 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 button with the words BACK ONLY. An indicator light on the switch will glow 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.
