Seating and Safety Restraints Pregnant women should always wear their safety belt. The lap belt portion of a combination lap and shoulder belt should be positioned low across the hips below the belly and worn as tight as comfort will allow. The shoulder belt should be positioned to cross the middle of the shoulder and the center of the chest. Vehicle sensitive mode Combination lap and shoulder belts in normal retractor mode allow 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 approximately 5 mph (8 km/h) or more, the combination safety belts will lock to help reduce forward movement of the driver and passengers. Belt sensitive mode Combination lap and shoulder belts can also be made to lock manually by quickly pulling on the shoulder belt. Automatic locking mode When to use the 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. This mode should be used any time a child safety seat (except a booster) 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. 170 2011 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
