Safety Belt Locking Modes
WARNING: After any vehicle crash, all safety belts should be
checked for proper function.
All safety restraints in the vehicle are combination lap and shoulder
belts. The driver safety belt and the optional front and rear center seat
safety belt have the first locking mode described below only. All outboard
passenger and outboard rear safety belts have both 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 about 5 mph (8 km/h) or
more, the combination safety belts will lock to help reduce forward
movement of the driver and passengers.
In addition, the retractor is designed to lock if the webbing is pulled out
too quickly. If this occurs, let the belt retract slightly and pull webbing
out again in a slow and controlled manner.
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 optional
front or rear center safety belt.
When to Use the Automatic Locking Mode
This mode should be used any time a child safety seat is installed in a
front outboard passenger seating position or any outboard rear seating
position (if equipped). The optional front and rear seat center safety belt
have a cinch mechanism. Children 12 years old and under should be
properly restrained in a rear seating position whenever possible. See the
Child Safety chapter.
