How to Reset Mercedes Transmission to Factory Settings?
1 Answers
First, insert the Mercedes key into the key slot, then turn it one notch to the right to reach the power-on but not started state. Then, press the Mercedes accelerator pedal all the way down and hold it for about 5 to 10 seconds without releasing. Next, turn the Mercedes key one notch to the left and wait until the engine turns off, but do not remove the key. Release the Mercedes accelerator pedal and wait for about 2 minutes. When you hear a slight 'click' sound, the transmission reset is complete.
