FORD 2014 Mustang v.3 - Manual (Page 38)

WARNING: The belt and retractor assembly must be replaced if
the safety belt assembly automatic locking retractor feature or
any other safety belt function is not operating properly when checked
by an authorized dealer. Failure to replace the belt and retractor
assembly could increase the risk of injury in crashes.
All safety restraints in the vehicle are combination lap and shoulder
belts. The driver safety belt has the first type of locking mode. The front
outboard passenger and rear seat safety belts have both types of locking
modes described as follows:
Vehicle Sensitive Mode
This is the normal retractor mode, which allows free shoulder belt length
adjustment to your movements and locking in response to vehicle
movement. For example, if the driver brakes suddenly or turns a corner
sharply, or the vehicle receives an impact of about 5 mph (8 km/h) or
more, the combination safety belts will lock to help reduce forward
movement of the driver and passengers.
In addition, the retractor is designed to lock if the webbing is pulled out
too quickly. If this occurs, let the belt retract slightly and pull webbing
out again in a slow and controlled manner.
Automatic Locking Mode
In this mode, the shoulder belt is automatically pre-locked. The belt will
still retract to remove any slack in the shoulder belt. The automatic
locking mode is not available on the driver safety belt.
When to Use the Automatic Locking Mode
This mode should be used any time a child safety seat, except a booster,
is installed in passenger front or rear seating positions. Children 12 years
old and under should be properly restrained in a rear seating position
whenever possible. See the Child Safety chapter.
