Look on the centre console area around the radio area, I think its either on left or right side of the radio or just below it. You’ll see a picture of a seat with 3 or 4 curvy lines thru the seat. Below this should be a thumb wheel switch with numbers printed on it, the higher the number the hotter the seat becomes. The switch closest to the left side of the vehicle (console or drivers seat) is for the left frnt seat, the switch closest to the right side is for the right frnt seat. In some years, the seats may not come on until the interior temperature drops below 45 f or so.

Please note, it will take a while for the seats to warm up; you may want to check with the dealership to see if your vehicle is subject to the heated seat recall (the elements were getting so hot that they burned the seat and also some people’s bottom!). Also, if the recall is done to your vehicle, you should know that the seat won’t get as hot as it previously did; the heated element replacement for the seat is limited in the temperature output.

Hope this helps, a car nut.
