Seats - Description and Operation

The front seats are equipped with the following serviceable components:

• Seat tracks
• Seat height adjust handle (driver only)
• Backrest frame
• Manual recliner handle
• Backrest static lumbar support
• Heated seat system components (optional)
• Backrest, cushion and head restraint covers
• Head restraint guide sleeves (on backrest frame)
• Cushion side shields
• Backrest and cushion foam pads
• Occupant Classification System (OCS) (part of passenger seat cushion)
• Seat side air bags (in seat backrests)
• Safety belt buckle and pretensioners (on seat tracks)
• Seat track position sensor (attached to driver seat track)
• Wiring harnesses (on seat tracks)

The 2-door front seat backrests are equipped with a release lever to tip the backrest forward for easy entry to second row seating. On the passenger seat, this lever also releases the seat track to slide the seat forward.

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

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.

The heated seat system includes the following serviceable components:

• Backrest and cushion heater mats (attached to seat cushion and backrest foam pads)
• Heated seat relay (attached underneath each front seat cushion frame)
• Heated seat switches (serviced only as part HVAC module)
• Thermostats (serviced only as part of each cushion heater mat)

The cushion and backrest 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. A heater mat cannot be reused; the 2-way tape adhesive will no longer hold the position on the foam pad causing it to shift or bunch up.

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.

The OCS system is standard equipment on all front outboard passenger seats. For information on diagnosing or servicing the OCS system, refer to Section 501-20B.

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 Section 501-20B.

The safety belt buckle and pretensioner removes excess slack from the safety belt webbing. For information, or if the safety belt buckle and pretensioner has deployed, refer to Section 501-20B.

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 parcel shelf)
• Cushion latches (located underneath cushion front edge attached to floor pan)
• Head restraints and head restraint guides (attached to the backrests)
