Child-Restraint System Types
In this owner's manual, explanation of child-restraint systems is provided for the following three types of popular child-restraint systems: infant seat, child seat, booster seat.
-
Installation position is determined by the type of child-restraint system. Always read the manufacturer's instructions and this owner's manual carefully.

Before purchasing a child-restraint system, it should be tested in the specific vehicle seating position (or positions) where it is intended to be used. If a previously purchased child-restraint system does not fit, you may need to purchase a different one that will.
