Figured it out.What a great feature. Why the hell is it not mentioned in "the book" and why isn't it a standard default thing?.
I'm off to get it activated.
If you try the long coding and all you see it bit0, bit1, bit2, etc. do this:
1. Module #36 Seats
2. Coding
3. Long coding helper (if you get a popup just click ok)
4. Tick Byte 3 Bit 1
5. Tick Byte 9 Bit 6
6. Exit
7. Do it! (Note: Good idea to take a picture of the computer screen first in case something goes wrong)
8. Car Off, Car On
9. Car Menu "Vehicle Settings" Tap "Seats"
10. "Seat Settings, Entry Assistance" Tap "Driver Seat"
It only moves a few inches for me. It will probably move further back if you are 5'5" - 5'10"
