In order to use the system, you need either a forward-facing child restraint that has attaching points (A) at its base and a top tether anchor (B), or a rear-facing child restraint that has attaching points (A), as shown here. CAUTION: If a LATCH-type child restraint isn't attached to its anchorage points, the restraint won't be able to protect a child sitting there. 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. See "Securing a Child Restraint in the Center Rear Seat Position (Extended Cab) and (Crew Cab)" or "Securing a Child Restraint in the Right Front Seat Position" in the Index for information on how to secure a child restraint in your vehicle using the vehicle's safety belts. With this system, use the LATCH system instead of the vehicle's safety belts to secure a child restraint. 1-56
