Rear Safety Belt Comfort Guides
Rear shoulder belt comfort guides may provide
added safety belt comfort for older children
who have outgrown booster seats and for some
adults. When installed on a shoulder belt, the
comfort guide positions the belt away from
the neck and head.
There is a guide for each outboard passenger
positions in the second row seat and all passenger
positions in the third row.
Here is how to install a comfort guide to the
safety belt:
1. For the outboard positions, remove the guide
from its storage clip on the interior body.
