Seats: Description and Operation

Seats

Front Seats

The front seats are equipped with the following serviceable systems:

- 2-way seat track (passenger only)
- 4-way seat track (driver only)
- Manual recliners (serviced with backrest frame)
- Heated seats (if equipped)
- Occupant Classification System (OCS) (passenger seat only, if equipped)
- Seat side air bags (in seat backrests) (if equipped)
- Safety belt buckles
- Seat track position sensors (if equipped)

Seat Backrests

The recliner mechanism is part of the seat backrest frame and is not serviced separately.

Seat Tracks

Front seats are equipped with a 2-way manual passenger seat track and 4-way manual driver seat track which includes a height adjust handle that ratchets to raise and lower the seat. Both seat tracks are serviced as complete assemblies which include the cushion frames and seat mounting feet.

Heated Seats

The heated seat system includes the following serviceable components:

- Cushion heater mats (attached to seat cushion foam pads)
- Heated seat relays (located in the Central Junction Box (CJB))
- Heated seat switches (located on the instrument panel)
- Thermostats (serviced only as part of each cushion heater mat)
- Body Control Module (BCM)

NOTE: If a new heater mat is needed on a front passenger seat cushion equipped with an Occupant Classification System (OCS) system, install a new OCS service kit with a heater mat already adhered to the cushion foam pad.

The cushion heater mats are serviceable separately. A heater mat can be peeled away from a foam pad and a new one adhered in its place providing excessive foam is not removed from the foam pad. If excessive foam is removed during removal, a new foam pad must be installed. A heater mat cannot be reused; the 2-way tape adhesive will no longer hold the heater mat position on the foam pad causing it to shift or bunch up.

Occupant Classification System (OCS) System

NOTE: OCS system components [seat wiring harness, seat cushion foam pad, bladder with pressure sensor and Occupant Classification System Module (OCSM)] are calibrated to each other and are serviced as an assembly. If new OCS system components are needed, an OCS system service kit must be installed as an assembly.

For information on diagnosing or servicing the OCS system, refer to Supplemental Restraint System Testing and Inspection.

Seat Side Air Bags

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 deployed, refer to Supplemental Restraint System Testing and Inspection.

Rear Seats

The rear seat cushion and 60/40 fold flat backrests are equipped with the following serviceable components:

- Backrest and cushion trim covers and foam pads
- Backrest hinges (attached to floor pan)
- Backrest latches (attached to backrest frame)
- Backrest latch strikers (attached to quarter panel)
- Cushion latches (located underneath cushion front edge attached to floor pan)
