2003 JEEP LIBERTY Owners Manual

Position the shoulder belt height adjusters so that
the belt rests across the middle of your shoulder.
Failure to adjust the safety belt properly could
reduce the effectiveness of the seat belt and increase
the risk of injury in a collision.

Using a seat belt extender when not needed can
increase the risk of injury in a collision. Only use
when the lap belt is not long enough when it is worn
low and snug, and in the recommended seating
positions. Remove and store the extender when not
needed.
