Energy management retractors

Your vehicle has a seat belt system equipped with energy management
retractors at the driver and front outboard passenger seating positions.
An energy management retractor is a device which pays out webbing in a
controlled manner. This feature is designed to help further reduce the
risk of force-related injuries to the occupant.
Seat belt systems equipped with an energy management retractor must
be replaced if they were in use during a frontal collision which resulted
in deployment of the frontal air bags. Refer to the Safety belt
maintenance section in this chapter.

Vehicle sensitive mode

The vehicle sensitive mode is the normal retractor mode, allowing 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.
