The passenger airbag on/off switch is standard equipment on all versions of this model that are equipped with the dual front airbag system, but are not equipped with a rear seat. See Fig 1. This switch is a two-position, resistor multiplexed switch with a single integral red Light-Emitting Diode (LED) and a non-coded key cylinder-type actuator. The switch is located on the passenger side end of the accessory switch bezel near the bottom of the instrument cluster center bezel to make the Off indicator visible to the front passenger seat occupant. When the switch is in its installed position, the only component visible through the dedicated opening of the accessory switch bezel is the key cylinder actuator. A small, tethered, molded plastic cap fits into the key cylinder actuator hole when the switch is not being used. The switch nomenclature and the Off indicator lens are integral to the accessory switch bezel. The text of the "Off" indicator is illuminated in amber when the Off position is selected with the ignition switch in the On position, while the On position of the switch is designated by text imprinted upon the accessory switch bezel, but is not illuminated. The remainder of the switch is concealed behind the accessory switch bezel.

The passenger airbag on/off switch housing is constructed of molded plastic and has three integral mounting tabs. See Fig 2. These mounting tabs are used to secure the switch to the back of the molded plastic accessory switch bezel with three small screws. The accessory switch bezel is secured to the instrument panel with four screws. A molded plastic connector receptacle on the back of the switch housing connects the switch to the vehicle electrical system through a dedicated take out of the body wire harness. The molded plastic harness connector insulator is keyed and latched to ensure proper and secure switch electrical connections. The passenger airbag on/off switch cannot be adjusted or repaired and, if faulty or damaged, the switch must be replaced.
