Vehicle sensitive mode
Combination lap and shoulder belts in normal retractor mode allow 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.
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
