The front outboard safety restraints in the vehicle are combination lap
and shoulder belts. The front passenger outboard safety belt has two
types of locking modes described below:
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.
Automatic locking mode (outboard front passenger seating
position only) for use with child safety seats
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
•Any time a child safety seat is installed in a passenger front seat.
Refer to Safety Restraints for Children orSafety Seats for Children
later in this chapter.

Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
front outboard passenger seating positions.
The safety belt pretensioner is a device which removes excess webbing
from the safety belt system. The safety belt pretensioner uses the same
crash sensor system as the front airbag supplemental restraint system
(SRS). When the safety belt pretensioner deploys, webbing from the lap
and shoulder belt is tightened. Refer to theSafety belt maintenance
section in this chapter.
WARNING: The driver and front passenger safety belt system
(including retractors, buckles and height adjusters) must be
replaced if the vehicle is involved in a collision that results in
deployment of front airbags and safety belt pretensioners.
Front safety belt height adjustment
Your vehicle has safety belt height adjustments for the driver and front
passenger. Adjust the height of the shoulder belt so the belt rests across
the middle of your shoulder.
• Regular Cab and four–door Cab
Plus 4
To lower the shoulder belt height, push the button and slide the height
adjuster down. To raise the height of the shoulder belt, slide the height
adjuster up. Pull down on the height adjuster to make sure it is locked in
place. WARNING: Position the safety belt height adjusters so that the
belt rests across the middle of your shoulder. Failure to adjust
the safety belt properly could reduce the effectiveness of the
seat belt and increase the risk of injury in a collision.
