To make the belt shorter, pull its free end as shown
until the belt is snug
4. Buckle, position and release the lap-shoulder belt
the same way as the other lap-shoulder belts. If
the belt is not long enough, see Safety Belt
Extender on page 1-42.
Make sure the release button on the buckle is positioned
so you would be able to unbuckle the safety belt
quickly if you ever had to.
Rear Safety Belt Comfort Guides for
Children and Small Adults
Rear safety belt comfort guides will provide added
safety belt comfort for older children who have outgrown
booster seats and for small adults. When installed on
a shoulder belt, the comfort guide better positions
the belt away from the neck and head.
There is a guide available for the center passenger
position in the second row rear seat. To provide added
safety belt comfort for children who have outgrown child
restraints and booster seats and for smaller adults, the
comfort guides may be installed on the shoulder belts.
