Driver Memory Seat

PRINCIPLES OF OPERATION - DRIVER MEMORY SEAT

Memory Power Driver Seat Operation
The memory driver seat feature allows the driver to program a personalized seat position that can be recalled using the memory switches or remote entry key fob. The memory feature uses an array of potentiometers to determine the positions of the mirrors, pedals and driver seat. The driver seat module (DSM) can store the settings for up to 2 drivers. When the driver presses the position recall button or uses the remote entry fob to unlock the vehicle, the motors adjust the mirrors, pedals, and the driver seat until the resistance of each potentiometer matches the memorized value.

Easy Entry/Easy Exit
The easy entry/easy exit feature of the driver seat moves the seat 2 inches rearward when the ignition key is removed (if the seat starts out in the most rearward position the easy entry/easy exit feature will not operate).

The easy entry/easy exit feature of the driver seat moves the seat up to 2 inches forward when the key is installed (if the seat had moved 2 inches rearward when the key was removed).

Programming Seat Positions
- A position setting may be recalled if the vehicle is in PARK or NEUTRAL and the ignition switch is not in the START position. After the DSM has initiated the recall, starting the engine or shifting out of PARK or NEUTRAL will not interrupt the process. The driver must move the seat to the desired position using the driver seat switch assembly. The driver must then depress the memory SET switch which activates the memory SET switch light emitting diode (LED). Within seconds (before the LED goes out), the driver must select a memory position. Memory 1 is selected by depressing memory switch 1. Memory 2 is selected by depressing memory switch 2. Memory 3 is selected by depressing both memory switch 1 and memory switch 2 simultaneously.
- If no memory switch input is received within the 5 second time limit, the operation is aborted and the memory SET switch LED is turned off. If one of the following inputs is received during the 5 second programming limit, the operation is aborted and the memory SET switch LED is turned off:
- Power driver seat switch
- Power outside rear view mirror switch
- Memory SET switch
- Power adjustable pedal switch

Recalling a Stored Seat Position

NOTE: A memory recall can be initiated only if the vehicle is in PARK or NEUTRAL gear and the ignition switch is not in START. A memory recall in progress will not be affected by moving the ignition switch to START or by moving the gearshift lever out of PARK or NEUTRAL.

Once the driver has stored the driver seat position, the driver can recall the setting by depressing the corresponding memory switch or by using a programmed remote entry transmitter.

- The driver can recall the desired driver seat position by depressing 1 or both of the memory recall switches. Depressing memory switch 1 will initiate a recall of the power driver seat position stored in memory 1. Depressing memory switch 2 will initiate a recall of the power driver seat position stored in memory 2. Depressing memory switch 1 and memory switch 2 simultaneously will initiate a recall of the power driver seat position stored in memory 3.
- A remote transmitter can be used to recall previously set memory positions. The transmitter that has been assigned with personality 1 is capable of recalling memory position 1 only. Similarly, the personality 2 and 3 transmitters can recall only memory positions 2 and 3, respectively.
- Memory recall occurs when the UNLOCK switch is depressed on the transmitter. The second depression of the UNLOCK switch, which unlocks passenger doors, does not initiate a memory recall.
- A memory recall in progress does not prohibit the initiation of another memory recall; the most recently requested memory recall will be executed.
