The front and rear outboard safety restraints in the vehicle are
combination lap and shoulder belts. The front passenger and rear seat
outboard 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 8 km/h (5 mph) or more, the combination safety belts will
lock to help reduce forward movement of the driver and passengers.

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.

When to use the automatic locking mode

Anytime a child safety seat 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.
