You'll also see warning labels on your vehicle. They use the same words, CAUTION or NOTICE.

The power seat controls are located on the outboard side of the front seat cushions. The horizontal control adjusts the seat cushion and the vertical control adjusts the seatback. Lift up or push down on the center of the seat control to move the entire seat up or down. To move the seat forward or rearward, slide the seat control forward or rearward. To recline the seatback, press the vertical control rearward. To raise the seatback, press the vertical control forward. Power Lumbar Your vehicle may have this feature. The driver's and passenger's seatback lumbar support can be adjusted by moving a control located on the outboard side of the seat cushions. To increase or decrease support, hold the control forward or rearward. Keep in mind that as your seating position changes, as it may during long trips, so should the position of your lumbar support. Adjust the seat as needed. Move the front of the seat control up or down to adjust the front portion of the cushion. Move the rear of the seat control up or down to adjust the rear portion of the cushion. 1-2 Heated Seats 1 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 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 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 inabout two minutes. To heat only the seatback, press the button with the words "BACK ONLY". An indicator light on the seatback switch will glow to designate that only the seatback is being heated. Additional presses will cycle through the heat levels for the seatback only. Press the horizontal button again to heat the whole seat. The feature will shut off automatically when the ignition is turned off. Power Reclining Seatbacks The vertical power seat control described earlier allows the seatback to recline. Sitting in a reclined position whel.;our vehicle is in motion can be dangerous. Even if you buckle up, your safety belts can't do their job when you're reclined like this. The shoulder belt can't do its job. In a crash, you could go into it, receiving neck or other injuries. The lap belt can't do its job either. In a crash the belt could go up over your abdomen.The belt forces would bethere, not at your pelvic bones. This could cause serious internal injuries. For proper protection when the vehicle is in motion, have the seatback upright. Then sit well back in the seat and wear your safety belt properly. But don't have a seatback reclined if your vehicle is moving. 1-4 Head Restraints Adjust your head restraint so tha ...
