Heated Seats If your vehicle has this feature, the controls are located on the outboard side of the front seats. Reclining Seatbacks To adjust a manual seatback, lift the lever on the outboard side of the seat. This feature will quickly heat the lower cushion and lower back of the driver's and front passenger's seats for added comfort. Press the lower part of the switch to turn the heater on low. Press the upper part of the switch to turn the heater on high. Put the switch in the center position to turn the heater off. The passenger's safety belt must be engaged for the heated seat feature to work on the passenger's seat. Release the lever to lock the seatback where you want it. To return the seat to an upright position, pull up on the lever without pushing on the seatback. If your vehicle is equipped with the vertical power seat control described in Power Seats on page 1-3, pressing it rearward allows the seatback to recline. 1-5
