To fasten the rear lap/shoulder belt:
1. Grasp the buckle and tongue plate.
2. Slowly pull the lap/shoulder belt out.

open end of the buckle (2) until an

4. Position the lap portion (1) of the belt
across your lap as LOW ON THE HIPS
as possible to reduce the risk of sliding
under it during an accident. Adjust the
belt to a SNUG FIT by pulling up on
the shoulder portion (2) of the safety
belt. The belt retractor is designed to
take up excess webbing automatically
and to maintain tension on the belt. For
your safety do not put any excess
slack into the safety belt.
