Second row comfort guide
The second row outboard
lap/shoulder belt is equipped with a
belt comfort guide. This guide is
attached to the quarter trim panel
and is used to adjust the comfort of
the shoulder belt for smaller
occupants in the outboard second
row seats.
To adjust the comfort guide:
1. Slip the shoulder belt into the
belt guide. (The portion of the belt
between the latch tongue and the
D-ring, not the portion where the
belt exits from the quarter trim
panel.)
2. Slide the guide up or down along
the webbing so that the belt is
centered on the occupant's shoulder.
WARNING: Position the safety belt comfort guide so that the
belt rests across the middle of your shoulder. Failure to adjust
the safety belt properly could reduce the effectiveness of the safety
belt and increase the risk of injury in a collision.
