Seats and Restraint System The ignition must be on for the heated seat feature to work. The seat will heat to the last setting if the ignition has been turned off and then turned back on. For the heated seat feature to work on the passenger seat the safety belt must be fastened. 1-5 Reclining Seatbacks { CAUTION You can lose control of the vehicle if you try to adjust a manual driver's seat while the vehicle is moving. The sudden movement could startle and confuse you, or make you push a pedal when you do not want to. Adjust the driver's seat only when the vehicle is not moving. The seats have manual reclining seatbacks. The lever used to operate them is located on the outboard side of the seats. If the controls are located on the center console, press the button to turn the heated seat and seatback on or off. Each time the button is pressed, the temperature settings change from high, to low, to off. Indicator lights on the button show the level of heat selected: two for high, and one for low. { CAUTION If either seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always push and pull on the seatbacks to be sure they are locked. To recline the seatback: 1. Lift the recline lever and move the seatback to the desired position, then release the lever to lock the seatback in place. 2. Push and pull on the seatback to make sure it is locked.
