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.

Children 12 years old and under should be properly restrained in the rear seat whenever possible.
