Seat Recall Functionality
A GIANT thank you is going out to PAmotorman the most comprehensive & proper explanation as to the operation, functionality, & logic for the seat operations. I would like mention how disgusted I am with GM & this perpetual withholding of information such as this... It's ridiculous & has to stop. PAmotorman's message is here, in it's entirety:

Power Memory Seat Operation
March 24, 2014
The power driver’s seat with memory recall and Easy Exit recall operations (Fig. 8) on some 2014 Corvettes (with the Memory Package, RPO AAB) may seem to operate erratically or intermittently. To help with diagnosis, it’s necessary to become familiar with the operational characteristics of this all-new system.
Fig 8
Some common comments include:
• The seat won’t recall when entering the vehicle
• The seat only moves when holding one of the memory buttons (button 1, 2 or the Exit button)
• The seat stops moving when releasing a memory button
• Sometimes the seat moves completely to the stored position by pressing and releasing a memory button
Seat Travel Limit Switches
The new Bulkhead Limit Switch, located on the left and right body harness conduit (Fig. 9), is used in both seating positions and acts to prevent damage to the body harness and seatback covers when the seat or seatback is moved in a rearward direction. When this switch is active (any time pressure is detected against the rear bulkhead/carpet area directly behind the seats), power seat movement is limited to movements that will bring the seat/seatback forward.
Fig 9
The new Seatback Unlock Switch, located inside the seatback assembly at the recliner mechanism, is used in both seat positions to prevent the seat from moving further rearward to ensure that the seatback can return to the normal upright position. When this switch is active (any time the seatback is manually folded forward), power seat movement is limited to movements that will bring the seat/seatback forward.
Both of these switches are viewable with the GDS2 scan tool. Common reasons for the Bulkhead Limit Switch being active are if the Easy Exit setting is stored in a position that applies pressure to the rear bulkhead or if an object is behind the seatback.
Supervised and Unsupervised Movements
Unlike prior models, the new system features unsupervised and supervised modes.
Unsupervised movement occurs when the operator has pressed and released, within 1/2 second, a memory button, which allows the seat to move on its own to a previously stored position.
TIP: Pressing any power seat button or memory button during unsupervised movement stops the seat. To resume recall operation, press and release, within 1/2 second, the desired memory button again.
Depending on transmission type, unsupervised movement will occur if:
• Automatic transmission – The vehicle ignition is on, the transmission is in Park, and the Bulkhead Limit Switch Seatback and Unlock Switch are both inactive.
• Manual transmission – The vehicle igntion is on, the clutch is depressed, the Parking Brake is applied, and the Bulkhead Limit Switch and Seatback Unlock Switch are both inactive.
Supervised movement occurs when a memory button is actively pressed and held, which allows the seat to move only while the operator is supervising the seat movement. Releasing the memory button will stop the seat movement. Only supervised memory recall operation can occur when the vehicle ignition is not in the On/Run Position. If the Bulkhead Limit Switch or Seatback Unlock Switch is active, either no operation will occur or supervised operation will occur, depending on which switch is active and the requested direction of seat travel.
Auto Memory Recall
The new memory seat system allows the operator to enable or disable the Auto Memory Recall operation of the seat. Auto Memory Recall is when the seat moves to a previously stored position either when opening the driver’s door or when the vehicle igntion is turned on. In order for auto recall to function, the feature must be turned on in the Settings menu of the infotainment system.
The operation of Auto Memory Recall is based on transmission type:
• Automatic transmission; At Driver’s Door Open – When the vehicle ignition is off and the Unlock key fob button is pressed, auto recall will occur if the driver’s door is opened with four minutes. The seat position will be recalled to the set position if the Bulkhead Limit Switch or Seatback Unlock Switch is inactive. If the driver’s door is already open, pressing the Unlock key fob button will cause the seat to recall to the desired position if the Bulkhead Limit Switch or Seatback Unlock Switch is inactive.
• Automatic transmission; At Ignition On – When the vehicle ignition button is pressed, the seat position will be recalled to the set position without a memory button being pressed if the Bulkhead Limit Switch or Seatback Unlock Switch is inactive.
• Manual transmission – The only available selection is on or off. If turned on, when the vehicle ignition is off and the driver’s door is opened, the seat position will be recalled to the set position if the Bulkhead Limit Switch or Seatback Unlock Switch is inactive.
Easy Exit
The new memory system also allows the operator to enable or disable the Easy Exit Automatic Recall operation of the driver’s seat. This feature recalls the current driver’s previously stored Exit button position when exiting the vehicle. In order for the Easy Exit feature to function, it must be turned on in the Settings menu of the infotainment system.
Easy Exit recall automatically activates when one of the following occurs:
• The vehicle is turned off and the driver’s door is opened within a short time.
• The vehicle is turned off with the driver’s door open.
• The Exit button is pressed.
TIP: Similar to Auto Memory Recall, the operation of the Easy Exit recall will differ based on Transmission type. Refer to the Supervised/Unsupervised Movements section.

Great, a detailed explanation of the ridiculous Auto Memory Recall operation
Manual transmission – The only available selection is on or off. If turned on, when the vehicle ignition is off and the driver’s door is opened, the seat position will be recalled to the set position if the Bulkhead Limit Switch or Seatback Unlock Switch is inactive.

The only thing they left out is what happens if the puck crosses the blue line before the bowler advances towards the wicket, and the player holding the ball has run more than three paces without bouncing it on the ground?

Mods please! This needs to be a sticky!! I and others have posted all of this info previously in ancient threads, but the confusion continues to arise. All of these details are essential.
One other tip for M7 cars. Program easy exit and memory1 to the same position if that is the key you are using. Program position 2 to the driving position. Then the seat etc will stay in the easy exit position when you open the door. Use button 2 with above precautions to set driving position with either supervised or unsupervised technique. Do the reverse for your other key.

Great write up by PAmotorman.
Sad that the functionality is non existent for M-7 cars.
The press and release works intermittently with my M-7 car. I have moved the easy exit forward a little to make sure I am not on the limit switch. Still works intermittently.
Sad that in my 06 GMC truck memory seats work great, or in the 07 Impala I got for my daughter memory seats work great, a cheep 21K car. My my 70K car by the same company they are the worst memory seats of any car I have ever been in.

Press and release always works for me.....IF BOTH the clutch is fully depressed AND the E brake is engaged. When it does not work I find that one or the other has not been done. Cumbersome and silly, but that is the design.
(And, of course, the seat rear travel limiter switch cannot be engaged or reached at any point during seat travel).
Heh heh...also be sure not to touch your nose with your left elbow..

I still don't understand why they would design this feature that puts a person in a awkward, unsafe position (sitting on the front of the seat) just to reach and push the clutch in to use the one touch. Move the seat before you start the car!!!!!!!!!!

One month old 2016 A8, Z51, 3LT. I have owned new C5 and C6 Vette's. The seat worked perfect 100% of the time on both cars. Get in -- start the car---seat/ mirror/ wheel moves. This new car is driving me crazy. I have set both FOB's to different settings. The entry recall is totally intermittent. It is set to ignition on.
The system works fine for 2-3 cycles then stops. The exit position always works. It seems that if anything alters a normal entry procedure, the system will not work. If I open the hatch, open the passenger door first, sit in the drivers seat for a minute....the entry memory system will not work. Dead. Even pressing and holding the #1 or #2 button has no effect. I have re-set both FOB 1 & 2 numerous times. I have had to reset #1 while out driving and stop to exit the car numerous times. 1800 miles!!!
I am really loosing patience. Any help?

I have a 2016 A8 Z51 2LT.
There's a Video showing how to set the seats.
Says to Shut Off Memory seats in Infotainment.
Then set the seat/wheel etc for Driving position and press the farthest Left button on the door and #1 button .. BOTH at the same time and hold until you hear 3 Beeps.
Then set the seat/wheel etc for Exit position and press the farthest Left button on the door and Exit button .. BOTH at the same time and hold until you hear 3 Beeps.
Then go back to Infotainment screen and Turn On Memory seats.
I did that and it didn't work, seats went where ever they felt like going.
So I went back in the Infotainment screen and Shut Off Memory seats.
Now, the Exit position works perfect and the seat moves to the Exit position I had previously set it to Automatically when I shut off the car and Open the door
When I got back in and started the car the seat did Not move to the Drivers Position.
So I Pushed and "Held" the #1 button and the seat Moved to the Drivers position I had previously set it at
And, the engine doesn't need to be running for it to go to the Drivers Position, as long as I hold the #1 button.
It's been working perfectly ever since
Yeah, I know it doesn't move to the Drivers Position Automatically, but I actually like it that way.
And I figured I'd leave well enough alone
Hope this helps someone

With all those words it does not address 2014 M7 owner's like myself (September 2013 build) issue of needing the clutch depressed before the car will start or having the alternate software installed (available end 2014.) I call that the "Push the start key twice option!"I learned in the year before the "optional software was introduced" to operate mine with a multitask approach and decided to stick with it.
I use two hands! While pulling the belt over to buckle with my right hand I hold my seat button in with a finger on my left! Then depress the clutch and the Start Button Once!
Since it's a DD it is a faster way to start the car. It also makes it easier to to use my right hand to grab the belt with the seat all the way back and not waste that movement pushing the Start Button to get the seat to move!
To each his own.

Seems like a a system that needs some tweaking. The memory function in my C5 has always worked perfectly - wonder why they made things more complicated for the C7?

2014, A6. Had trouble initially and, thanks to the Forum, finally understood the bulkhead switch and got the seat working. When I start the car the seat moves forward to a set position. But that position is one I set when I first got the car. Later I got a better driving position and saved it. But it still reverts to the old position when I start the car. But when I press the 1 button it goes to my preferred position. No problem, but it is weird. There is nothing I can do to make it forget that old setting. Perhaps disconnect the battery but I am not prepared to do that. It's just weird that it has two setting saved.
