To switch the retractor from the emergency
locking mode to the automatic locking mode,
perform the following steps:
1. Buckle the lap/shoulder combination belt.
2. Grasp the shoulder portion of the belt and
pull downward until all of the belt is
extracted and, when allowed to retract, a
clicking sound is heard. At this time, the belt
retractor is in the automatic locking mode
(child restraint mode).
3. A clicking sound will continue to be heard
as the belt is allowed to retract.
NOTE: When the combination lap/shoulder
belt is unbuckled and allowed to
retract completely, the retractor will
switch back to the vehicle sensitive
(emergency) locking mode. See the
detailed instructions under Safety Seats
for Children in this chapter.

cornering or impacts of approximately 5 mph
(8 km/h) or more. The retractor cannot be made
to lock by pulling on the belt.
