Power Seat System
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 available driver and passenger side eight-way power seat includes a six-way adjustable seat cushion track and a two-way power seat back. The power seats can be adjusted up, down, front up, front down, forward, rearward, recliner forward, and recliner rearward. An available two-way power lumbar support can be adjusted forward and rearward. The power seat system is also available with a memory seat option that automatically positions the power seat for two different drivers.
The power seat adjuster contains two reversible motors that are connected to worm-drive gearboxes that move the seat adjusters through screw-type drive units. These motors are the height adjust motor and the front tilt motor. The third motor on the power seat adjuster is responsible for the fore and aft movement of the power seat. The fore/aft motor is a reversible motor that is connected through two flex drive cables to a worm-drive gearbox that moves the seat adjuster through a screw-type drive unit. Each motor contains a self-resetting circuit breaker to protect it from overload. Consecutive or frequent resetting of the circuit breakers may damaged the motors.
The power seat adjuster assembly includes the following major components:
- Front Tilt Motor - located on the upper power seat adjuster assembly. Controls the up and down movement of the seat front only. Is available as a service part and if inoperative or damaged can be replaced.
- Height Adjust Motor - located on the rear of the lower power seat adjuster assembly. Controls the up and down movement of the entire seat. Is available as a service part and if inoperative or damaged can be replaced.
- Fore/Aft Motor - located on the upper power seat adjuster assembly. Controls the fore and aft movement of the power seat. Is a reversible motor that is connected through two flex drive cables to a worm-drive gearbox that moves the seat adjuster through a screw-type drive unit. Is available as a service kit that includes the flex drive cables and if inoperative or damaged can be replaced.
The power seat back assembly includes the two following major components:
- Power Lumbar Motor - located on the inboard side of the seat back. Controls the in and out movement of the lumbar support.
- Power Seat Recliner Motor - located on the outboard side of the seat back. Controls the up and down movement of the seat back.
The power lumbar support and power seat recliner cannot be adjusted or repaired and if inoperative or damaged, the entire seat back must be replaced as an assembly.
The front power seat is controlled by the two following switches located on the outboard seat cushion side shield.
- Power Seat Switch (1) - has paddle-type levers. Vehicles may be equipped with driver only, or driver and passenger power seat switches. One seat switch is used for each front seat. Movement of the seat cushions and backs mimics the action of the switch paddles. The driver power seat switch type (memory or non-memory) can be identified by the color of the switch electrical connector receptacle. Memory switches have a light gray connector receptacle and non-memory have a black receptacle.
- Power Lumbar Switch (2) - is a four way switch. Press front of switch and lumbar protrudes out of the seat back. Push rear of switch and lumbar recedes into the seat back. Same concept applies for up and down buttons.
Auto Advance 'n Return ™
Both front seats feature the optional Auto Advance 'n Return ™ system. The driver and front passenger seats can be moved with the push of a button to make room for people to get into the 2nd row. A one-touch Auto Advance 'n Return button is located on the B-pillar trim panel, just in front of the power sliding door.
The button is only functional when the power sliding door is open and the vehicle is in PARK. If the door is not open or the vehicle is not in PARK when the button is pushed, the front seat will not move and a message will be displayed in Instrument Panel Cluster (IPC). If the power sliding door is closing when the button is pushed, the front seat will not move and a message will be displayed in the IPC.
The Auto Advance 'n Return system includes obstacle detection. When the system detects an obstacle, the seat will stop, reverse direction, and return to the previous location. A message will be displayed in the IPC indicating that an obstacle has been detected.
If calibration of the front seat is lost, the seat will automatically calibrate when the Auto Advance 'n Return button is pushed. This may result in the seat cushion moving forward and downward, before moving to the location that will allow space for the second row Stow 'n Go seat movement.
