Memory System

NOTE: Vehicle transmission must be in Park position and seat belt unlatched to recall memory positions.

Memory system is an optional feature that consists of driver's power seat (except lumbar), both outside mirrors and radio station presets. Memory module for seat is mounted under driver's seat. Memory seat is available with or without heated seat option. Memory Seat Module (MSM) stores position of driver's seat and driver/passenger's seat heaters (if equipped). Driver's Door Module (DDM) stores position of driver's mirror and Passenger's Door Module (PDM) stores position of passenger's mirror. Radio station presets are stored in radio. Memory switch is located on driver's door panel. When memory switch is pressed, DDM sends signal along PCI bus to other modules to recall set memory locations. If Remote Keyless Entry (RKE) transmitter is used to recall memory positions, PDM will send signal to other modules for memory recall.
