1-8. Safety information STEP 4 Fully extend the shoulder belt and then allow it to retract slightly in order to activate the ALR lock mode. Lock mode allows the seat belt to retract only. STEP 5 While pushing the child restraint system into the rear seat, allow the shoulder belt to retract until the child restraint system is securely in place. After the shoulder belt has retracted to a point where there is no slack in the belt, pull the belt to check that it cannot be extended. STEP 6 If the child restraint has a top tether strap, the top tether strap should be latched onto the top tether strap anchor. (→P. 158) 156 PRIUS v_U (OM47784U)
