Kia Optima: Restraint / Seat Belt Pretensioner (BPT)
Description and operation
The Seat Belt Pretensioners (BPT) are installed inside center pillar (LH & RH).
When a vehicle crashes with a certain degree of frontal impact, the pretensioner
seat belt helps to reduce the severity of injury to the front seat occupants by
retracting the seat belt webbing. This prevents the front occupants from thrusting
forward and hitting the steering wheel or the instrument panel when the vehicle
crashes.

Never attempt to measure the circuit resistance of the Seat Belt
Pretensioner (BPT) even if you are using a specified tester. If
the circuit resistance is measured with a tester, the pretensioner
will be ignited accidentally. This will result in serious personal
injury.
