Rear Safety Belt Comfort Guides
This vehicle may have rear shoulder belt comfort guides
for each outside passenger position in the rear seat.
If not, they are available through your dealer. The
guides may provide added safety belt comfort for older
children who have outgrown booster seats and for some
adults. When installed the comfort guide positions the
shoulder belt away from the neck and head.
Here is how to install a comfort guide to the safety belt:
1. Remove the guide from its storage pocket on the
rear side of the seatback.
2. Place the guide over the belt, and insert the two
edges of the belt into the slots of the guide.
