Seat Backrest Latch Release

The front seat backrests are equipped with a latch release and cable assembly to tip the backrest forward for easy entry to second row seating.


Seat Tracks

Manual front seats are equipped with a 2-way manual passenger seat track or 4-way manual driver seat track which includes a height adjust handle that ratchets to raise and lower the seat.

Power seats are equipped with a 6-way power seat track and a seat-mounted control switch to move the seat horizontally and vertically (front and rear height). Seat track motors are part of a power seat track assembly and are not serviceable separately.


Heated Seats

The heated seat system includes the following components:

- Heated seat relays attached under the driver seat cushion frame
- Heated seat switches and indicators located on the instrument panel [part of the Front Controls Interface Module (FCIM)]
- Heater mats attached to the seat cushion and backrest foam pads
- Thermostats (serviced only as part of each cushion heater mat)


Lumbar Support

The lumbar supports are mounted vertically in the backrest frame and provide more lower body displacement for front seat occupants. The adjustable power lumbar switch is attached to the seat cushion side shield.


Manual Recline

The manual recline can be adjusted by a handle mounted on the outboard side of the cushion side shield. The recliners are serviceable only as part of a new backrest frame.


Occupant Classification Sensor (OCS)

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.

The OCS system is standard equipment on all front passenger seats. For information on diagnosing or servicing the OCS system, refer to the appropriate procedure in Restraint Systems.


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 the appropriate procedure in Restraint Systems.
