airbag is off. SeeFront passenger sensing systemin theAirbag
supplemental restraint system (SRS)section of this chapter.
Front safety belt usage sensors
The front safety belt usage sensors detect whether or not the driver and
front outboard passenger safety belts are fastened. This information
allows your Personal Safety System to tailor the airbag deployment and
safety belt pretensioner activation depending upon safety belt usage.
Refer toSafety belt usage sensorslater in this chapter.
Front outboard safety belt pretensioners
The safety belt pretensioners at the front outboard seating positions are
designed to tighten the safety belts firmly against the occupant’s body
during frontal collisions, and in side collisions and rollovers. This helps
increase the effectiveness of the safety belts. In frontal collisions, the
safety belt pretensioners can be activated alone or, if the collision is of
sufficient severity, together with the front airbags.
Front outboard safety belt energy management retractors
The front outboard safety belt energy management retractors allow
webbing to be pulled out of the retractor in a gradual and controlled
manner in response to the occupant’s forward momentum. This helps
reduce the risk of force-related injuries to the occupant’s chest by
limiting the load on the occupant. Refer toEnergy management
retractorssection in this chapter.
Determining if the Personal Safety System is operational
The Personal Safety System uses a warning light in the instrument
cluster or a back-up tone to indicate the condition of the system. Refer
to theWarning lights and chimessection in theInstrument Cluster
chapter. Routine maintenance of the Personal Safety System is not
required.
The Restraints Control Module (RCM) monitors its own internal circuits
and the circuits for the airbag supplemental restraints, crash sensor(s),
safety belt pretensioners, front safety belt buckle sensors, and the driver
seat position sensor. In addition, the RCM also monitors the restraints
warning light in the instrument cluster. A difficulty with the system is
indicated by one or more of the following.
•The warning light will either flash or stay lit.
•The warning light will not illuminate immediately after ignition is
turned on.
•A series of five beeps will be heard. The tone pattern will repeat
periodically until the problem and warning light are repaired.

Safety belt systems equipped with an energy management retractor must
be replaced if they were in use during a frontal collision which resulted
in deployment of the frontal airbags. Refer to theSafety belt
maintenancesection in this chapter.
Safety belt locking modes
All safety restraints in the vehicle are combination lap and shoulder
belts. The driver safety belt and the optional front center seat’s safety
belt have the first locking mode only. All outboard passenger and 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 approximately 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 seat’s center safety belt.
When to use the automatic locking mode
This mode should be usedany timea child safety seat is installed in a
front outboard passenger seating position in a Regular Cab / SuperCab /
SuperCrew or any rear seating position of a SuperCab or SuperCrew. The
optional front seat’s center safety belt has a cinch mechanism. Refer to
Safety belt with cinch tongue earlier in this chapter. Children 12 years
old and under should be properly restrained in a rear seat whenever
possible. Refer toSafety restraints for childrenorSafety seats for
childrenlater in this chapter.

Safety belt pretensioner
Your vehicle is equipped with safety belt pretensioners at the driver and
right front passenger seating positions.
The safety belt pretensioner removes some slack from the safety belt
system at the start of a crash. The safety belt pretensioner uses the
same crash sensor system as the front airbags and Safety Canopy
System. When the safety belt pretensioner deploys, the lap and shoulder
belt are tightened.
When the Safety CanopySystem and/or the front airbags are activated,
the safety belt pretensioners for the driver and right front passenger
seating positions will be activated when the respective seatbelt is
properly buckled.
WARNING:The driver and the right 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 or Safety CanopySystem and safety belt
pretensioners.
WARNING:Failure to replace the safety belt assembly under
the above conditions could result in severe personal injuries in
the event of a collision.
Refer to theSafety belt maintenancesection in this chapter.
Safety belt usage sensors
The driver and front outboard passenger safety belt buckles are
equipped with sensors that detect if the safety belts are fastened. The
sensors provide information to the Personal Safety Systemwhich can
then adapt the airbag deployment or safety belt pretensioner activation
based upon safety belt usage.
WARNING:The Personal Safety Systemprovides the most
benefit to belted occupants. The system monitors and tailors the
airbag deployment based upon safety belt usage. Failure to properly
wear your safety belt will increase your risk of injury.
