FORD 2003 F-550 v.1 - Manual (Page 70)

The front and rear outboard safetyrestraints in the vehicle are
combination lap and shoulder belts. The front passenger and rear seat
outboard safetybelts have two types of locking modes described below:
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 suddenlyor turns a corner
sharply, or the vehicle receives an impact of approximately 8 km/h (5
mph) or more, the combination safetybelts will lock to help reduce
forward movement of the driver and passengers.
On SuperCab and CrewCab models, the front seat belt system can also
be made to lock manuallybyquicklypulling on the shoulder belt.
Rear seat belts (if equipped) cannot be made to lock up bypulling
quicklyon the belt.
Automatic locking mode
The automatic locking mode is not available on the driver safetybelt.
When to use the automatic locking mode
In this mode, the shoulder belt is automaticallypre-locked. The belt will
still retract to remove anyslack in the shoulder belt. The automatic
locking mode is not available on the driver safetybelt.
This mode should be used any time a child safetyseat is installed in a
passenger front or outboard rear seating position (if equipped). Children
12 years old and under should be properly restrained in the rear seat
whenever possible. Refer to Safety restraints for children or Safety
seats for children later in this chapter.
How to use the automatic locking mode
