Yes, it should light up and go off as a power on test. Heres the exact details from the manual:
The Passenger Airbag Disable (PAD) Indicator Light (an amber light located in the center of the instrument panel) tells the driver and front passenger when the front passenger airbag is turned off. The “PAD Indicator Light” illuminates the words PASS AIR BAG OFF� to show that the passenger airbag will not inflate during a collision requiring airbags. When the right
front passenger seat is empty or when very light objects are placed on the seat, the passenger airbag
will not inflate even though the “PAD Indicator Light” is not illuminated. The “PAD Indicator Light” should not be illuminated
when a adult passenger is properly seated in the front passenger seat. In this case, the airbag is ready to be inflated if a collision requiring an airbag occurs. For occupants classified into the “child” size category, the “PAD Indicator Light” will be illuminated indicating that the front passenger airbag is turned off and will not inflate. If the “PAD Indicator Light” is not illuminated, DO NOT assume the airbag is turned off and move the child restraint to the rear seat. A deploying passenger
airbag can cause death or serious injury to a child in a rear facing infant seat.
