Manual 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.

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.

Power Reclining Seatback

Driver Seat with Manual Lumbar, Power Seat Control, and Power Recline shown


Object Number: 1684980  Size: B3

The driver seat may have a power reclining seatback. The control used to operate it is located on the outboard side of the seat cushion rear of the horizontal power seat control.

    • Press the control rearward to recline the seatback.
    • Press the control forward to raise the seatback.

Caution: Sitting in a reclined position when the vehicle is in motion can be dangerous. Even when buckled up, the safety belts cannot do their job when reclined like this.

The shoulder belt cannot do its job because it will not be against your body. Instead, it will be in front of you. In a crash, you could go into it, receiving neck or other injuries.

The lap belt cannot do its job either. In a crash, the belt could go up over your abdomen. The belt forces would be there, 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 the safety belt properly.
