When the battery is jumped, why do certain features stop working?
What is your question?
I just purchased this low mileage(~49,000 miles)SL320 and noticed that the top control button was on and the soft top, roll bar, radio did not work. The dealer told me they would look into it and what they found was some "codes that had to be reset"; this seemed to take care of the problems. The car sat in my garage for two days and when I tried to start it everything was dead. Figuring it was a dead battery, I jumped it, started the car and noticed that the same problems, as I found at the dealership, had returned: the radio, the top button is lit, the roll bar does not work. Is this typical when a battery is jumped or changed? Am I doing something wrong? I have the code for the radio but, I have no idea what to do for the top, roll bar and any other functions that might be nonfunctional. Thank you for your time.

These cars don't like to be jumped. Especially not at the battery. After you've made all the necessary repairs to the charging system then several modules will have to be checked and damaged components replaced. Many vehicles have rolled through the doors that needed large repairs after the tow truck driver tried to jump the vehicle...s
