slowly return it to the stowing position.
■When installing a child restraint system
You may need a locking clip to install the child restraint system. Follow the instruc-tions provided by the manufacturer of the
system. If your child restraint system does not provide a locking clip, you can purchase the following item from any authorized
Lexus retailer or Lexus authorized repairer, or any reliable repairer: Locking clip for child restraint system (Part
No. 73119-22010)
■ISOFIX rigid anchors (ISOFIX
child restraint system)
Lower anchors are provided for the
each rear seat. (Buttons displaying the
location of the anchors are attached to
the seats.)
WARNING
■When installing a child restraint sys- tem
Observe the following precautions. Failure to do so may result in death or serious injury.
●Do not allow children to play with the
seat belt. If the seat belt becomes twisted around a child’s neck, it may lead to choking or other serious inju-
ries that could result in death. If this occurs and the buckle cannot be unfastened, scissors should be used to
cut the belt.
●Ensure that the belt and plate are securely locked and the seat belt is not twisted.
●Shake the child restraint system left
and right, and forward and backward to ensure that it has been securely installed.
●After securing a child restraint system,
never adjust the seat.
●When a junior seat is installed, always ensure that the shoulder belt is posi-tioned across the center of the child’s
shoulder. The belt should be kept away from the child’s neck, but not so that it could fall off the child’s shoulder.
●Follow all installation instructions pro-
vided by the child restraint system manufacturer.
