With memory, position sensors are attached to the left seat and to 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, located in the armrest on the left front door trim panel, records and recalls the seat positions. The seat position can be recorded for 2 different drivers. In order to record a seat position, the MEMORY-1 or the MEMORY-2 button of the memory function switch is pressed and held for 3 seconds. A chime acknowledges the input. When the MSM receives a memory set message, the MSM records the feedback voltages from the position sensors for the appropriate driver.

When the MEMORY-1 or the MEMORY-2 button is pressed, a single chime is sounded in order to acknowledge the input. When the memory seat module (MSM) receives the memory recall message, the MSM then 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 (MSM) 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.
