Front Seats

All front seats are fitted with the following features as standard:

integral side air bags
head restraints
safety belt buckle/pretensioner

The driver and passenger seats, although almost identical, have some unique components fitted. The driver seat has a seat track position

sensor and the passenger seat has a weight sensing system. In both instances the components form an integral part of the occupant
restraint system.
For additional information, refer to:

Seat Position Sensor

(501-20B Supplemental Restraint System, Removal and Installation) /

Occupant Classification Sensor

(501-20B Supplemental Restraint System, Removal and Installation).

The high option front seat has the following features:

electrically adjustable seat positioning
electrically adjustable lumbar support (optional)
heated seat (optional)

The basic option front seat has the following standard features:

electrically adjustable seat height positioning (driver seat only)
heated seat (optional)

Seat Position Memory (Optional)

The seat position memory can be programmed for up to three different driver seat configurations and the seat memory switch, located in
the seat control switch pack, can be used to store and retrieve the programmed configurations.

The seat position memory front seat has the following features:

electrically adjustable seat positioning with three position memory
electrically adjustable lumbar support
heated seat (optional)

Heated Seats (Optional)

The heated seat system comprises:

heated seat module (incorporated in the seat control switch pack on vehicles with seat position memory)
heated seat switches
backrest heater element
cushion heater element and thermostat

The heated seat function permits the electrical heating of the seat back and cushion on the driver and front passenger seats. The heating
system of each seat is selected by separate switches located at the top of the center console.

Pressing the appropriate switch activates the first stage of a three stage operation of the heated seat function:

one press of the switch activates the high setting (providing a seat surface temperature of approximately 42°C).
a second press of the switch activates the low setting (providing a seat surface temperature of approximately 37°C).
a third press of the switch deactivates the heating function.

Once the heated seat function has been activated, it will persist until one of the following conditions have been satisfied:

A fixed period of time has expired (10 minutes).
The engine is not running.
The function is deactivated by pressing the switch for a third time.
A malfunction is detected by the heated seat module.

Confirmation that the heated seat function is active is indicated by the illumination of the relevant switch, a yellow light indicates the low
temperature setting and a red light indicates the high temperature setting.

Heated Seat Module

The heated seat module is located behind the outer side trim panel of the front seat on vehicles without seat position memory, and is
incorporated in to the seat control switch pack on vehicles with seat position memory. The module controls the seat heating function by
providing the appropriate response depending on the status of the heated seat switches.

Power Lumbar Support

The power lumbar is a self-contained unit controlled directly by the seat mounted power lumbar switch. On vehicles with seat position
memory, the power lumbar switch is incorporated in to the recliner switch in the seat control switch pack.

Rear Seats - 4-Door

Depending on the market specification the rear seats will be one of the following:

fixed bench style seat
folding 70/30 split seat

Folding Seatbacks (if equipped)

The rear seatbacks can be folded forward to provide additional luggage space if required. Release handles for each seat back are located in
the luggage compartment under the parcel shelf on 4-door vehicles, and on the top of the each seatback on wagon.

Rear Seats - Wagon

The rear seats on wagon are of the folding type with a 70/30 split, fitted with a folding armrest in the left-hand seat backrest. The
left-hand seat also incorporates the rear centre safety belt retractor, which has a release cable connected to the rear seat backrest latch to
prevent the safety belt from operating if the rear seat backrest is not in the fully latched position.

Head Restraints

The front seat head restraints are adjustable for height and forward and rearward tilt.

The rear seat head restraints can be set to one of two height positions. The optional centre rear seat head restraint (excluding Federal
specification vehicles) can also be set to one of two height positions.

Ski Hatch - 4-Door Vehicles only (if equipped)

Skis or similar objects can be stowed in the vehicle by utilizing the two door hatch fitted to the rear seat. The inner door is accessible after
folding down the armrest, the second door is accessible from inside the luggage compartment. A sack complete with strap is provided for
holding the stored items, the strap connects to the center rear seat belt buckle to secure the sack and contents.
