Folding the Seatbacks {CAUTION: If the seatback is not locked, it could move forward in a sudden stop or crash. That could cause injury to the person sitting there. Always press rearward on the seatback to be sure it is locked. The seatbacks on the bucket seats may be folded forward to give you more cargo space. On extended models with rear bucket seats, the head restraints need to be removed in order to fold the rear seats. To do this follow these directions: 1. Lift the head restraints up until they stop. 2. Press in the button on the side of the head restraint guide cap and lift up on the head restraint. 3. Do the same for the other cap. The head restraint can be removed and stored in the space provided in the folded up seat cushion. To fold the seatbacks on the bucket seats, do the following: 1. Pull up on the strap loop located at the rear of the seat cushion and pull the seat cushion up. Then fold it forward. 1-20
