Occupant Classification Sensor

CAUTION: If installing only the front passenger seat cushion trim cover, the occupant classification sensor must be rezeroed.

The occupant classification sensor is found only on the front passenger seat and was not equipped on all vehicles. A white tag having the letters "OCS" (Occupant Classification Sensor) will appear under the front of the passenger seat identifying a seat equipped with an occupant classification sensor.

Lumbar Support
The optional lumbar support system consists of the following components:
- lumbar seat control switch
- front seat backrest pad adjuster

Power Recliner
The optional power recliner is a modular design and incorporated into the inertia front seat backrest latch. The individual components cannot be repaired or installed new.

The power recliner tilts the seat backrest backward or forward and is controlled by the seat regulator control switch.

The power recliner cannot be repaired separately. If the power recliner needs to be repaired, the entire front seat backrest latch must be installed new.

Heated Seat
Each heated seat is controlled by a switch on the door trim panel.

The heated seat system:
- will only operate with the ignition switch in RUN.
- will operate with battery voltage as low as 9 volts.
- will maintain a temperature automatically once it is selected.
- will heat to the selected temperature each time the ignition switch is turned to RUN if the heated seat is not switched OFF.

Seat side air bag
Optional driver and passenger seat side air bags are attached to the seat backrest frame. For diagnostic information or if the seat side air bag has been deployed, refer to Air Bag Systems.

Front seat backrest trim covers installed on seats with seat side air bags cannot be repaired. The front seat backrest trim covers are to be installed new. Cleaning is permissible.

If a seat side air bag deployment took place, a new seat back pad, trim cover and seat side air bag module must be installed. Install a new seat back frame, if necessary.
