Seats: Description and Operation

The power seat system allows the driver and front seat passenger to electrically adjust their seating positions using the power seat switches located on the outboard seat cushion side shield of each front seat. The power seat system allows the seating position to be adjusted forward, rearward, front up, front down, rear up, or rear down. The power seat system receives battery current through a fuse in the Integrated Power Module, regardless of the ignition switch position. The power seat system includes the following components:
- Driver Power Seat Switch
- Passenger Power Seat Switch
- Driver Power Seat Track
- Passenger Power Seat Track

Some models equipped with the power seat option also feature a manually operated lumbar support in the seat back. The lumbar support allows the user to adjust lower seat back pressure to achieve optimum comfort and support in the lower lumbar region of the spinal column. The lumbar support is controlled by a knob on the outboard side of the seat back assembly.

The power seat system receives battery current through a 50 amp fuse in the Power Distribution Center (PDC) so that the power seats remain operational, regardless of the ignition switch position.

When a power seat switch is actuated, a battery feed and a ground path are applied through the power seat switch contacts to the appropriate motor or motors. The motor and drive unit operate to move the seat in the selected direction until the switch is released, or until the travel limit of the power seat track is reached. When the switch is moved in the opposite direction, the battery feed and ground path to the motor is reversed through the switch contacts. This causes the motor to run in the opposite direction.
