how do you change the clock on the Mercedes GL 450.

SOURCE: where do you add transmission

This is only a guess. I don't know anything about Mercedes. try the transmission dipstick hole. Generally all cars use the transmission dipstick hole to add transmission fluid. That is why the tranny dipstick is slightly larger than the oil dipstick. Good luck and thanks for your question and I hope my suggestions help. burdfrenzy

even I am seeing the same issue on my GL450 AND I bought Certified Pre Owned in March 2010 same model as yours. Last time when I had this MB service updated software but that didn't fix it. Now they cannot reproduce the same so couldn't apply any fix. Please let me know if you were able to get it fixed

This light is telling you that there is an electronic fault that only a "scan" tool can decipher. Ask your friends who their mechanic is, have it scanned, and have it serviced. Problems like this cannot be repaired over the internet.
