With this system, use the LATCH system instead of the vehicle's safety belts to secure a child restraint. {CAUTION: If a LATCH-type child restraint is not attached to its anchorage points, the restraint will not be able to protect the child correctly. In a crash, the child could be seriously injured or killed. Make sure that a LATCH-type child restraint is properly installed using the anchorage points, or use the vehicle's safety belts to secure the restraint following the instructions that came with that restraint, and also the instructions in this manual. To assist you in locating the lower anchors for this child restraint system, each seating position with the LATCH system has a label on the seatback at each lower anchor position. The labels are located on the inboard and outboard positions of the rear seats. 1-54
