Note: Unlike the standard seatbelt, the
inflatable seatbelt's unique lap portion locks

for the shoulder portion of the belt to move
freely is normal, even after the lap belt has
been put into the automatic locking mode.
Note: The lock-off device on some child
restraints may not accommodate the
shoulder portion of the inflatable seatbelt.
Follow all instructions provided by the
manufacturer of the child restraint regarding
the necessary and proper use of the lock-off

have been provided only for use in vehicles
with seatbelt systems that would otherwise
require a locking clip.

to make sure the retractor is in the
automatic locking mode (you should

retractor is not locked, unbuckle the
belt and repeat Steps 5 and 6.
