It's a 2004 Volkswagen Passat. It has 3 memory buttons and one red "Memory Reset" button. The red button can be toggled on and off. I set the seat in position and held button 1 until the car made a beep. Then, I changed the position of the seat and pressed button 1, but nothing happened. I tried this with all 3 buttons. Also, how do you change the clock and see the average mpg? The car did not come with an owners manual.
