Best to you.

Principles of Operation
The driver seat module (DSM) is on the controller area network (CAN) communication network. To support several vehicle subsystems, the module permits intermodule and diagnostic tool communications.
The DSM controls the memory driver seat and the passenger memory power exterior mirror. This passenger memory power exterior mirror feature allows the driver to program personalized mirror positions. Once the driver stores a mirror position, the driver can recall the setting by pressing the corresponding memory switch or by using a programmed remote keyless entry (RKE) transmitter. For additional information, refer to Section 501-10 .

Driver Seat Module - Memory Seat
The power driver seat, power outside rear view mirrors and power adjustable pedals are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option. The DSM is located on the driver seat track.
This system allows automatic positioning of the driver seat to 2 programmable positions.

• A power driver seat position can be stored at any time. 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 5 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.
• If no memory switch input is received within the 5-second time limit, the operation is aborted and the memory seat position switch (set switch) LED is turned OFF. This also occurs if one of the following inputs is received during the 5-second programming limit:
  • Driver seat control switch
  • Memory seat position switch (set switch)
  • Power adjustable pedal switch

A programmed seat position can only be recalled when the transmission selector is in PARK or NEUTRAL with the ignition switch in the RUN position. A position may be programmed at any time.

Easy Entry/Easy Exit
The driver power seat easy entry/easy exit feature can be enabled/disabled. Refer to Section 418-01 or the owner's literature.

This may need to be done with a scan tool

See pg. 3-31 in owners manual. Start car in park. Adjust seat, telescoping wheel, and side view mirrors. Pust Mem button and then within 5 sec. push either 1 or 2. That button should light to show memory stored.
From the 2012 Guide (See link)
l"AUTOMATIC DRIVE POSITIONER (if so equipped) Two positions for the driver's seat, steering column and outside mirrors can be stored in the automatic drive positioner memory. Follow these procedures to set the memory positions: • Confirm the shift lever is in the P (PARK) position. • Push the ignition switch to the ON position. • Adjust the driver's seat, steering column and outside mirrors to the desired positions using the adjusting switches for each feature. • Push the SET switch and within 5 seconds, push the memory switch (1 or 2) for at least 1 second. • The indicator light on the memory switch you select will illuminate for approximately 5 seconds. • The driver's seat, steering column and outside mirror positions are now set to your preference. These memorized positions can also be linked to your NISSAN Intelligent Key®. For more information, refer to the "Pre-driving checks and adjustments (section 3)" of your Owner's Manual." https://owners.nissanusa.com/content/techpub/ManualsAndGuides/Murano/2012/2012-Murano-quick-reference-guide.pdf
For added info see whole owners manual.

I am not sure about changing the name as my 2000 park ave. only indicates driver one or driver two. To reset the memory for seat/ mirror position is rather simple: with the ignition on and the car in park, adjust your seat and mirrors to the desired position. Then press and hold the desired button (driver one or two) until you hear a beep, This is the procedure that works on my 2000 park ave. I hope this helps you.

The dirver seat module is attached to the underside of the seat frame. It must be calibrated if replaced. The dealer can use a tool to get failure codes (DTCs) from teh module. 1/2 hour labor charge to extract codes.


Front Seats
The front seats have the following features:

• Driver memory
• Power lumbar (optional)
• Manual lumbar
• Horizontal, vertical front and rear tilt adjustments (driver)
• Horizontal, vertical front tilt adjustment (passenger)
• Power recline
• Climate controlled (optional)

Adjustment of the seat may be accomplished with the seat control switch located on the side of the seat.
--------------------------------------------------------------------
Principles of Operation
Driver Power Seat - Memory
NOTE: The memory power seat track may stall when operating at 0°C (32°F) or below. Once the vehicle's interior temperature rises above 0°C (32°F), normal operation should return.
The driver power seat is controlled by the driver seat module (DSM). The DSM does not need to be configured, however the driver seat does need to be calibrated when the DSM is installed. The driver seat control switch provides voltage to the DSM when activated. The NEUTRAL position of each driver seat control switch position is a ground state through the seat control switch contacts. A voltage input causes the DSM to power the appropriate motor until the input is removed. Ground is the normal state of the motor circuits through the DSM and is not switched to control the motors. The DSM internally switches the appropriate line from ground to power to adjust the motors.
As the seat is adjusted, the DSM constantly monitors the motor position sensors to record the current seat position. The DSM will remove power from the motor upon termination of the seat control switch input or if the DSM does not see movement from the motor by monitoring the position sensor. The DSM must be calibrated to the seat track it is controlling. For additional information, refer to Seat Calibration. Once the DSM is calibrated to the seat track, it will only allow movement within the calibrated range.
Seat Calibration
The DSM is calibrated using a diagnostic tool. The calibration procedure automatically powers the driver power seat through its full range of motion and records the FULL STOP positions by monitoring the motor position sensors. Once the FULL STOP positions or range of the seat have been recorded, the DSM will only operate within the calibrated range. Any input attempting to drive the seat beyond the calibrated range will be ignored. This calibration is used for all seat control functions including manual switch control and memory recall positioning. During the seat calibration, the DSM may identify a function that is inoperative, such as a position sensor not changing. If the DSM identifies a concern that has a related diagnostic trouble code (DTC), the DSM will set the related DTC at the end of the validation procedure.
The calibration procedure powers the seat track adjustments to the end of their travel, which is determined by the DSM sensing a change of state in the motor position sensors. If there is a concern with the seat track or motor position sensor that limits the travel, the DSM will interpret the stopping point as the end of travel and store the position. The DSM is not able to determine if the seat has moved to its FULL TRAVEL position. It is only capable of monitoring and storing the amount of travel seen by the position sensor changing states.
For additional information on carrying out the power seat calibration procedure, refer to the diagnostic tool operating manual.
Memory Seat
Memory seat positioning can be recalled with the memory switches on the driver door panel or a programmed remote keyless entry transmitter. In either case, the DSM receives a memory recall 1 or 2 command from the driver door module (DDM) over the SCP communication network. The memory recall switches are a hardwired input to the DDM. The DDM also receives the remote keyless entry transmitter signals. Once a valid memory recall command is received from the DDM, the DSM moves the driver seat to the position stored in memory by powering the appropriate motors and monitoring the motor position sensors until the position is reached.
This system allows automatic positioning of the driver seat to 2 programmable positions.

• To program position 1, move the driver seat to the desired position using the seat control switch. Depress the set button. Within 5 seconds, depress button 1.
• To program position 2, repeat the previous procedure using the set button and button 2.
• To recall position 1, depress button 1. To recall position 2, depress button 2.

A position can only be recalled when the transmission selector is in PARK or NEUTRAL. A position may be programmed at any time.
Easy Exit/Easy Entry
The easy exit function moves the seat backwards about 2 inches when the ignition key is removed from the ignition switch. The DSM receives a key out command over the SCP communication network and powers the driver seat rearward. This function will not operate if the seat is less than the travel distance to the end of the track, or the function has been deactivated at the message center driver personality settings. The DSM will also cancel this operation if a valid input command is received, such as the seat control switch or memory recall request.
The DSM will record the current seat position before powering the seat for an easy exit function. This recorded position will be used to return the seat to this position on the easy entry operation. During easy entry operation, the seat is returned to the position previous to the easy exit operation. Easy entry operation will be cancelled if a valid input command is received by the DSM.
Passenger Power Seat
The passenger power seat motors are hardwired to the passenger seat control switch. The circuits are normally at ground through the seat control switch. The individual circuit is switched to power when the specific adjustment position is selected.

That is probably because the setting for the mirror had been saved in the memory along with the setting for the driver's seat position (if your model has programmable memory for seat position. Set the mirror in the most convenient position and also the driver's seat. Press and hold the MEM button on your driver's seat and press any of the memory numbers. This will store those settings in the memory so that even if someone else alter these setting, the mirror and the seat will be adjusted to the memorised setting when you use the remote to open the car.

The exterior mirrors:

• are controlled by power controls on the LH front door trim panel.
• are of a foldaway design.
• may contain turn signal indicators.
• may be heated when the heated back window glass is activated.
• may have a programmable recall memory option.

Driver Seat Module
The power driver seat and power exterior mirrors are controlled by the driver seat module (DSM) only when the vehicle is equipped with the programmable/recall memory option.
---------------------------------------------------------------------
Power Exterior Mirror Operation
The power exterior mirrors are controlled by the DSM and are operational all the time, whether the ignition switch is on or off. Using the power exterior mirror switch, the driver can adjust the driver and passenger exterior mirrors four ways.
