Energy management retractors

Your vehicle has a safety 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.
Safety 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 airbags. Refer to the Safety belt
maintenance section in this chapter.
The front and rear safety restraints in the vehicle are combination lap
and shoulder belts. The front passenger outboard and rear outboard seat
safety belts have two types of locking modes described below:

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.
The front outboard safety belts can also be made to lock manually by
quickly pulling on the shoulder belt. Rear safety belts (if equipped) can
also be made to lock up by pulling quickly on the belt.

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, or
the Regular Cab center safety belt.
