• Front and rear seats
The front outboard and rear safety restraints in the vehicle are
combination lap and shoulder belts. The front outboard passenger and
rear seat safety belts have three types of locking modes described as
follows:
Vehicle sensitive mode
This is the normal retractor mode, which allows 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.
Webbing extraction sensitive mode
The webbing sensitive locking mode locks the webbing and prevents
more belt from being pulled out if the belt is pulled out too quickly. The
belt will unlock when you stop pulling on it.
