On certain vehicles, the front passenger seat occupant detection mat can fatigue during field usage depending on the seat configuration, vehicle geometry, manner and frequency of front passenger entry/exit. Over time micro cracks could develop in the side flanks of the mat, which could lead to a break of the conductive path and the system will recognize a failure and with exception of head protection system the front passenger air bag will be deactivated. The airbag On/Off lamp will be illuminated to make the occupants aware of the deactivation. Correction: The occupant detection mat will be granted a warranty extension of 10 years.
