OVERVIEW
Two variants of driver and passenger seat are available
- Low line seat with 8-way adjustment finished in Blenheim leather
- High line seat with 10-way adjustment finished in Oxford leather

| Item | Part Description |
|---|---|
| 1 | Low line front seat |
| 2 | High line front seat |
The front seats are fitted with the seat belt bolted to the seat rail. The frames are common to both variants and are equipped with the following
- Seat control switches
- Cushion front height adjustment
- Cushion rear height adjustment
- Cushion front tilt adjustment (high line only)
- Backrest adjustment
- Head restraint adjustment
- Lumbar adjustment
- Seat forward and rearward adjustment
- Side air bag module
- Backrest heating
- Cushion heating
- Seat climatic control (available as an option on the high line version)
| WARNING | WARNING: Prior to removal of the front seats and before disconnecting the front seat wiring harness electrical connectors (which includes the side air bag module electrical connectors), the battery ground cable should be disconnected and a period of at least 1 minute allowed to elapse. The same amount of care should be taken when handling and storing the front seats, as would be taken when handling and storing air bag modules. |
Both variants of the front seats are fitted with a manually adjustable folding armrest on the inboard side of the seat. The memory recall functions are also available on higher specification vehicles.
The driver and passenger front seats, although almost identical, have some unique components. The front driver seat has a seat position sensor and the front passenger seat, for North American Specification (NAS) vehicles, has a seat occupant classification system, where as Rest Of the World (ROW) vehicles, except Australia, has a seat occupancy detection system. In both instances the components form an integral part of the Supplemental Restraint System (SRS). For additional information, refer to: Air Bag and Safety Belt Pretensioner Supplemental Restraint System (SRS) - Description & Operation.
The rear bench seats are designed to fold forward to increase the rear load space. a 60:40 split gives the owner increased flexibility when loading the vehicle with large objects. All rear seats are equipped with 3-point seat belts and adjustable head restraints. High line specification vehicles are also fitted with seat cushion heaters in both outboard seats.

PRINCIPLE OF OPERATION
For a detailed description of the seating systems and operation, refer to the relevant Description and Operation instructions of the workshop information. Refer to Seats..
PINPOINT TEST G: HEATING AND COOLING - NOISY OPERATION
Pinpoint Test G
- Check the Climate Controlled Seat Module for stored DTC's.
- WARNING: Before work is carried out, make the air bag supplemental restraint system safe. For additional information, refer to Standard Workshop Practices instructions of workshop information.
- NOTE: The Climate Controlled Seat's (heat and cool) function will only operate when the vehicle's engine is running.
- NOTE: If a fault is identified and repaired, check for correct operation of the driver and front-passenger climate controlled seat (heat and cool) functions.
- There is a known issue which effects a limited number of vehicles where under acceleration of the vehicle the occupant of seat can deform the suspension mat (snake wire) which then presses on the casing of the seat backrest climate assembly, this causes the casing to distort and the noise issue to occur. If contact has occurred there will be a witness mark on the casing. Carry out visual inspection of the seat backrest climate assembly that has been identified as noisy by the customer.
- Operate the heat and cool function of the seat. Listen for a 'WAH WAH' noise (the fan speeds up and slows down repeatedly).
- Compare the noise level of the suspect climate seat assembly to another climate seat assembly.
PINPOINT TEST I: HEATING AND COOLING - HEAT OR COOL OPERATION SLOW
Pinpoint Test I
- Check the Climate Controlled Seat Module for stored DTC's.
- WARNING: Before work is carried out, make the air bag supplemental restraint system safe. For additional information, refer to Standard Workshop Practices instructions of information.
- NOTE: The Climate Controlled Seat's (heat and cool) function will only operate when the vehicle's engine is running.
- NOTE: If a fault is identified and repaired, check for correct operation of the driver and front-passenger climate controlled seat (heat and cool) functions.
- Check the heat and cool function at the cushion.
- Check the condition of the bellows.
- Check the security of the bellows duct.
- Check the security of the bellows.
- Compare the operation of the suspect climate seat assembly to another climate seat assembly.
PINPOINT TEST J: HEATING AND COOLING - INTERMITTENT OPERATION
Pinpoint Test J
- Check the Climate Controlled Seat Module for stored DTC's.
- WARNING: Before work is carried out, make the air bag supplemental restraint system safe. For additional information, refer to Standard Workshop Practices instructions of information.
- NOTE: The Climate Controlled Seat's (heat and cool) function will only operate when the vehicle's engine is running.
- NOTE: If a fault is identified and repaired, check for correct operation of the driver and front-passenger climate controlled seat (heat and cool) functions.
- Identify from customer concern or stored DTC's which Seat Climate Assembly is operating intermittently and confirm the harness connector is fully connected.
PRINCIPLES OF OPERATION
Heated seats incorporate heater elements in the cushion and the backrest of the seat. Each cushion heater element has a thermal sensor, which supplies a feedback temperature signal to the related seat heater module. The backrest heater elements do not have a thermal sensor, and are regulated at the same temperature as the cushion heater elements.
For a detailed description of the seat heater mat, refer to the relevant Description and Operation instructions in the information. Refer to Seats..
