Two variants of driver and passenger seat are available; 10-way sports and 16-way luxury. The front seat frames are common to both the coupe and convertible and are equipped with the following
- Seat control switches (door mounted)
- Front seat cushion front height adjustment
- Front seat cushion rear height adjustment
- Front seat backrest adjustment
- Front seat head restraint adjustment
- Lumbar adjustment
- Front seat forward and backward adjustment
- Side air bag module
- Front seat backrest heating
- Front seat cushion heating
- Extendible seat-cushion (luxury variant only)
- Adjustable side bolsters (luxury variant only)
| 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. |
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 has a occupancy sensing system. In both instances the components form an integral part of the air bag Supplemental Restraint System (SRS). Refer to Air Bag Supplemental Restraint System (SRS) article.
The rear seat squabs are conventionally trimmed over a wire frame with a removable center panel allowing access to the auxiliary junction box.

Seat position is monitored by the individual seat modules using seat track position Hall sensors incorporated into the motors. This prevents the seat from being adjusted to a position that will contact the surrounding interior trim or a rear seat passenger causing injury (clash avoidance). Seat memory is standard on both drivers and passenger seats. Each seat memory can be configured for 3 personality positions, which are set using the seat memory switch and stored in the individual seat module.
The switches for electrically adjusting the seats are wired directly to the appropriate control module, which controls the movement of the seat via Local Interconnect Network (LIN) serial communication protocol.
Note. In the event of a control module failure a fly lead behind the seat valance can be used to connect a power source directly to the seat slide motor. This enables the seat to be moved to gain access to the front and rear seat fixings. The seat can then be removed from the vehicle in order to access the control module.

| 1 | Fly lead |
As part of the Pre-Delivery Inspection (PDI) each seat needs to perform a clash avoidance check. This procedure is to ensure there is no contact between the seat trim and rear quarter casing. If there is any contact between the seat trim and rear quarter casing the affected seat must be recalibrated via the seat calibration routine in the Integrated Diagnostic System (IDS). For more information refer to the PDI information.
Scheme 9
| Item Number | Description |
|---|---|
| 1 | Seat back heater |
| 2 | Seat cushion heater |
Operation of the heated seats is controlled by the Automatic Temperature Control (ATC) module. The ATC module receives a request from the Touch Screen Display (TSD) and sends a message to the Central Junction Box (CJB), which then provides a feed to the seat heater elements. Refer to Control Components article.
Scheme 10
| Item Number | Description |
|---|---|
| 1 | Head restraint support |
| 2 | Fabric tape |
| 3 | Headrest movement during rear end collision |
| 4 | Occupant movement during rear end collision |
Both front seats are fitted with mechanical active head restraints that reduce injuries to the spinal column and possible whiplash in the event of a rear collision. The 2 supports of the head restraints inside the seat backrest are joined together with fabric tape. As the seat occupant's back and body weight presses against the fabric tape the head restraint moves upwards and forwards mechanically by means of a pivot point. The movement of the headrest cushions the occupant's head, altering the posture and reducing the relative motion between the body and the head. The head restraint then returns to it's original position using a spring return mechanism.
Scheme 11
| Item Number | Description |
|---|---|
| 1 | Occupancy sensor pad |
| 2 | Harness connector |
| 3 | Control module |
Occupant monitoring provides the Restraints Control Module (RCM) with the occupancy status of the front passenger seat.
The occupant detection system determines if the front passenger seat is occupied or unoccupied. The system consists of a pressure sensor installed between the foam padding and the cover of the front passenger seat cushion. From the occupancy status, and the status of the front passenger safety belt, the instrument cluster determines the seat belt minder status. Refer to Air Bag Supplemental Restraint System (SRS) article.
Scheme 12
| Item Number | Description |
|---|---|
| 1 | Release cable |
| 2 | Release lever |
The front seats tilt forward to allow access to the rear seats. To tilt the seat forward remove the seat belt from the seat belt guide. Lift the lever and push the seat back forwards. The seat back will latch when returned to the normal position. Ensure that the seat belt is returned to the seat belt guide.
