information early in the crash event on the severity of the impact. This

allows your Personal Safety System to distinguish between different

levels of crash severity and modify the deployment strategy of the

dual-stage air bags and safety belt pretensioners.

Driver’s seat position sensor

The driver’s seat position sensor allows your Personal Safety System to

tailor the deployment level of the driver dual-stage air bag based on seat

position. The system is designed to help protect smaller drivers sitting

close to the driver air bag by providing a lower air bag output level.

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 Belt section in this chapter.

Front safety belt pretensioners

The front outboard safety belt pretensioners are designed to tighten the

safety belts of the driver and front ouboard passenger firmly against the

occupant’s body during a collision. This maximizes the effectiveness of

the safety belts and helps properly position the occupant relative to the

air bag to improve protection. The safety belt pretensioners can be either

activated alone or, if the collision is of sufficient severity, together with

the 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 Belt 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 Light 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),
