# Service bulletin B720417

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Acoustic and visual warnings indicate that the front passenger seat is occupied, and the safety belt is not fastened when the seat is actually unoccupied. If the situation is currently present, sit in the seat and move the seat to a slightly different position. The POL \(Passenger Occupancy Light\) light should now function correctly. In some cases, the air bag Warning Light was illuminated. Advanced Crash Safety Module \(ACSM\) fault "930A1C \- Front passenger seat occupancy detection transmitting fault \(moisture\)" is stored.
