Essential Safety Equipment Seats Never allow a passenger to sit or stand on the folded seatback while the vehicle is moving: Driving with a passenger on the folded seatback is dangerous. Allowing a child to sit up on the folded seatback while the vehicle is moving is particularly dangerous. In a sudden stop or even a minor collision, a child not in a proper seat or child-restraint system and seat belt could be thrown forward, back or even out of the vehicle resulting in serious injuries or death. The child in the baggage area could be thrown into other occupants and cause serious injury. Never give the car keys to children and do not allow them to play in the vehicle (4 Door): Playing with the folding rear seats is dangerous. The folding rear seatbacks cannot be folded down from inside the trunk. Once the seatbacks are back up, a child in the trunk would not be able to get out the way they had entered. If you have small children, keep the seatbacks locked. Always leave your car locked and keep the car keys safely away from children: Leaving your car unlocked or the keys in reach of children is dangerous. Children who find their way into the trunk through an unlocked rear seatback or an open trunk can become accidentally locked in the trunk. This could result in death or brain damage from heat prostration, particularly in the summer. Always lock the doors and the trunk, and as an added measure, keep the rear seatbacks locked, whether you have children in your home or not. Do not leave the key in your vehicle with children and keep them in a place where your children will not find or play with them: Leaving children in a vehicle with the key is dangerous. This could result in someone being badly injured or even killed. Children may find these new kinds of keys to be an interesting toy to play with and could cause the power windows or other controls to operate, or even make the vehicle move. NOTE When returning a rear seat to its original position, also replace the seat belt to its normal position. Verify that the seat belt pulls out and retracts. 2-10
