CAUTION
When installing a child restraint system
If child restraint system regulations exist in the country where you reside,
please contact any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional for the child restraint system installa-
tion.
When a junior seat is installed, always ensure that the shoulder belt is
positioned 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. Failing to do so may result in death or serious injury in the event
of an accident or a sudden braking.
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.
Follow all installation instructions provided by the child restraint system
manufacturer.
To correctly attach a child restraint system to the anchors
When using the lower anchors, be sure that there are no foreign objects
around the anchors and that the seat belt is not caught behind the child
restraint system. Make sure the child restraint system is securely attached,
or it may cause death or serious injury to the child or other passengers in
the event of a sudden braking or an accident.
