Rear Safety Belt Comfort Guides
Your vehicle may have rear safety belt comfort guides
for the rear outside positions.
Rear safety belt comfort guides may provide added
safety belt comfort for older children who have outgrown
booster seats and for some adults. When attached to
a shoulder belt, the comfort guide positions the belt
away from the neck and head.
Here is how to attach the comfort guide to the
shoulder belt.
1. Slide the guide off of its storage clip located
between the interior body and the seatback.
