Lexus 2003 LS Owner's Manual page 181

A Both high–positioned lap belts and loose–fitting
belts could cause serious injuries due to sliding
under the lap belt during a collision or other
unintended result. Keep the lap belt positioned as
low on child's hip as possible.
A For child's safety, do not place the shoulder belt
under child's arm.
A After inserting the tab, make sure the tab and buckle
are locked and that the lap and shoulder portions of
the belt are not twisted.
A Do not insert coins, clips, etc. in the buckle as this
may prevent your child from properly latching the tab
and buckle.
A If the seat belt does not function normally,
immediately contact your Lexus dealer. Do not use
the child restraint system until the seat belt is fixed.
It cannot protect your child from injury.
