Asr is on, 1 month car unused

[drebdy]

hello benz experts, i need your inputs, after having a vacation for a month my car's battery has drained out and it would no longer start, hence i replaced it w/ a new battery and then it started fine but the ASR is now on and acceleration is really bad but when the car hits 60kph it ok and back to normal, engine runs smooth but the acceleration is really bad, could this be caused by the prolonged weak battery in the car, do i need to have the car ressetted at the dealership? or do i have a broken ASR relay, need your inputs help me, thanks in advance,
