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 air bag deployment and

safety belt pretensioner activation depending upon safety belt usage.

Refer to Safety restraints section in this chapter.

Front 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 when the

vehicle is equipped with the Safety Canopy娂 system. This maximizes 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 air bags.

Front 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 to Safety restraints section 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 the Warning lights and chimes section in the Instrument 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 air bag 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 the 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.
