Lexus GS300 1998 Owner's Manual page 192

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.
Failure to do so could reduce the amount of protection in an
accident and cause serious injuries in a collision.
D High–positioned lap belts and loose–fitting belts
both 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 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 you from properly latching the tab and
buckle.
D If the seat belt does not function normally,
immediately contact your Lexus dealer. Do not use
the seat until the seat belt is fixed. It cannot protect
your child from injury.
