the beginning of this chapter.
Safety Belts for All Passenger Outboard
Seating Positions
Your vehicle is equipped with a dual locking
mode retractor on the shoulder belt portion of
the combination lap/shoulder safety belt for the
front and rear outboard passenger seats.
Dual locking mode retractors operate in two
ways:
Vehicle sensitive (emergency) locking mode
In this operating mode, the shoulder belt
retractor will allow the occupant freedom of
movement, locking tight only on hard braking,
hard cornering or impacts of approximately
5 mph (8 km/h) or more. The retractor can also
be made to lock by pulling/jerking on the belt.
