� When you sell your vehicle , we urge you to inform the buyer that the vehicle is equipped with seatbelt pretensioners . Also , notify the buyer of the contents in this section . ■ Front seatbelt with Shoulder Belt Pretensioner

The pretensioner sensor also serves as follows .
� Front impact sensors � Side impact sensors � Rollover sensor
If the sensor detects a certain predetermined amount of force during frontal or side collisions or rollover accidents , any seatbelt that has a seatbelt pretensioner is quickly drawn back in by the retractor to take up the slack so that the belt more effectively restrains the seat occupant .
The front seatbelt pretensioner includes a tension reducing device which limits the peak forces exerted by the seatbelt on the occupant in the event of a collision . The front passenger ' s side adaptive force limiter will select a reducing load to suit the body size of the occupant as detected by the occupant detection sensor .
When a seatbelt pretensioner is activated , an operating noise will be heard and a small amount of smoke will be released . These occurrences are normal and not harmful . This smoke does not indicate a fire in the vehicle .
Once the seatbelt pretensioner has been activated , the seatbelt retractor remains locked . Consequently , the seatbelt cannot be pulled out and retracted and therefore must be replaced . ■ System Monitors
A diagnostic system continually monitors the readiness of the seatbelt pretensioner with the ignition switch in the “ ON ” position . The seatbelt pretensioners share the control module with the SRS airbag system . Therefore , if any malfunction occurs in a seatbelt pretensioner , the SRS airbag system warning light will illuminate .
