CAUTION

A forward±facing child restraint system should be put on
the front seat only when it is unavoidable. Always move the
seat as far back as possible, because the force of a deploying
airbag could cause death or serious injury to the child.

If you must put the convertible seat on the front seat, make
sure the seat belt hanger is secured in raised position. For
details, see page 117 in the ºSeat beltº.

1. Sit the child on a booster seat. Run the lap and shoulder
belt through or around the booster seat and child following the
instructions provided by its manufacturer and insert the tab
into the buckle.
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 ºSeat beltsº on page 115 for details.

COMFORT ADJUSTMENT

CAUTION

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 pr otection in an
accident and cause serious injuries in a collision.

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.

For child's safety, do not place the shoulder belt under
child's arm.

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.

Do not insert coins, clips, etc. in the buckle as this may
prevent you from properly latching the tab and buckle.

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.
