Some customers may comment about 5 slow chimes, with no obvious reason. If the customerwould check the PPS display, they would notice the passenger seat belt indicator isilluminated. Dealers should be aware that when certain conductive objects are placedon the front passenger seat, the front passenger airbag indicator may illuminate.The seat belt reminder light/chime may also be activated. Examples of objects thatcould enable theairbag include:
Computers, Electronic TabletsCharging and Audio CablesCell PhonesTech 2®Large Container of LiquidGroceriesAn electronic device does not necessarily need to be turned on to cause this condition.
Because this vehicle is equipped with low risk passenger airbags, the PPS system isdesigned to turn the airbag on for most front seat occupants and turn the airbag offfor small children in child seats. The system works by detecting the capacitance ofthe object on the seat, not the objects weight; and certain conductive objects willenable the airbag. The passenger seat belt reminder system is active when the passengerairbag is on.
