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.

NOTE

Installation position is determined by the type of child-restraint system. Always read the manufacturer's instructions and this owner's manual carefully.
