Heated Seats Your vehicle may have heated seats. If it does, the heated seat switches are located in the instrument panel switchbank. Reclining Seatbacks This feature will quickly heat the lower cushions and lower back of the driver's and front passenger's seat. The left switch is for the driver's seat and the right switch is for the front passenger's seat. Press the top of the switch to turn the heater on. Press the bottom of the switch to turn the heater off. The heated seat switch will turn off when the ignition is turned to OFF and will resume operation when the ignition is turned to ON, unless the switch is turned off To adjust the seatback, pull up on the lever located on the outboard sides of both the driver's and the front passenger's seats. It is easier to recline the seat if you lean forward, taking your weight off the seatback. 1-6
