The left and the right power seat systems each consist of the following components:

All motors operate independently of each other. The motors are controlled by the seat switch. The seat switch is located on the outboard side of each seat. Both vertical motors run simultaneously in order to move the entire seat up and down. The horizontal motor moves the seat forward and back. The recline motor moves the angle of the seat back. The headrest motor moves the headrest up and down.

The left and the right lumbar systems each consist of the following components:

All motors operate independently of each other. The motors are controlled by the lumbar switch. The lumbar switch is located on the outboard side of each seat. The lumbar horizontal motor located in the seat back moves the lumbar support toward the occupants back. The lumbar vertical motor moves the support up and down along the seat back.

With memory, there are position sensors attached to each of the left seat and the left lumbar motors, with the exception of the left headrest motor. The position sensors are monitored by a memory seat module (MSM). A memory function switch is located in the armrest on the left front door trim panel. The memory function switch records and recalls seat positions. Seat position may be recorded for 2 different drivers. In order to record a seat position, press and hold for 3 seconds the MEMORY-1 or MEMORY-2 button of the memory function switch. A chime will sound in order to acknowledge the input. When the memory seat module receives a memory set message, the module records the feedback voltages from the position sensors for the appropriate driver.

When the MEMORY-1 or MEMORY-2 button is pressed, a single chime sounds in order to acknowledge the input. Then, the memory seat module receives the memory recall message. The MSM applies battery positive voltage to the seat motors until the position sensor feedback voltages equal the feedback voltages stored in memory for the appropriate driver. When a keyless entry transmitter is used in order to unlock the vehicles doors, the remote function actuator (RFA) module communicates the unlock command and which driver performed the command to the MSM via a class 2 message. The driver has a number of personalized recall options when recalling stored seat positions.

In order to move the seat manually, the memory seat module receives the seat manual movement inputs from the left seat switch. When an input is received, the MSM supplies battery positive voltage to the appropriate motor(s) and the seat moves accordingly.

The left and the right heated seats system consists of the following components:

When the heated seat switch is pressed the heated seat module applies battery positive voltage to the seat. The heated seat module monitors the seat surface temperature through a thermistor and maintains a pre-determined temperature. When the heated seat switch is pressed once, the heated seat module will set the seat temperature to high. When the heated switch is pressed a second time, the heated seat module will set the seat temperature to low. After the third press, the heated seat module stops applying battery positive voltage to the heating elements. The heated seat module will also turn off the heated seats whenever the ignition switch has been turned off.
