When I turn off the drivers seat moves backwards and does the reverse when I start up.
Does anybody know how to stop this feature?

[/B]Simply turn the selector switch on the left side of the steering column from center (Auto) to Pedal or Column.

What I do is position the switch as per the advice, and in addition, move the seat back a bit and enter this into the 2nd memory setting. When I exit the car I can then move the seat back myself if I want to. I found that the seat moves too far back if you let the auto feature work. This gets round that excessive movement.

Disconnecting the battery, will erase any seat memory setting on either of mine. Just adjust seat where you like it, & leave it alone. That was what was done to mine, found out after working on it early on, as i had to disconnect the battery.
