Adjustable Headrests WARNING: B080C02Y To recline the seatback, lean forward to take your weight off it, then pull up on the recliner control lever at the outside edge of the seat. Now lean back until the desired seatback angle is achieved. To lock the seatback into position, release the recliner control lever. To minimize risk of severe injury in the event of a collision or a sudden stop, both the driver and passenger seatbacks should always be in an upright position while the vehicle is in motion. The protection provided by the seat belts and airbags may be reduced significantly when the seatbacks are reclined. There is greater risk that the driver and passenger will slide under the seat belt which may result in serious injury if a crash occurs when the seatbacks are reclined. The seat belt cannot provide full protection to an occupant if the seat back is reclined. Lock Knob HXG200J Headrests are designed to help reduce the risk of neck injuries. To raise the headrest, pull it up. To lower it, push it down while pressing the lock knob. If equipped with a horizontally adjustable type of headrest, pull on the top.
