1. Sit the child on a booster seat. Run the lap and shoulder belt
through or around the booster seat and across the child
following the instructions provided by its manufacturer and
insert the tab into the buckle taking care not to twist the belt.
Make sure the shoulder belt is correctly across the child's
shoulder and that the lap belt is positioned as low as possible
on child's hips. See "Seat belts" on page 101 for details.

CAUTION
D Always make sure the shoulder belt is positioned
across the center of child's shoulder. The belt should
be kept away from child's neck, but not falling off
child's shoulder. Otherwise, the child may be killed
or seriously injured in the event of sudden braking or
a collision.
D Both high-positioned lap belts and loose-fitting
belts could cause death or serious injuries due to
sliding under the lap belt during a collision or other
unintended event. Keep the lap belt positioned as
low on a child's hip as possible.
D For child's safety, do not place the shoulder belt
under child's arm.
D 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.
D Do not insert coins, clips, etc. in the buckle as this
may prevent your child from properly latching the tab
and buckle.
D If the seat belt does not function normally, it cannot
protect your child from death or serious injury.
Immediately contact your Lexus dealer. Do not put
the child restraint system on the seat until the seat
belt is fixed.
