Hi, Arnel which tool are you using? Which Ml 500? Is it a 164.175 4matic or the 164.172
4Matic anyway never the less if you are using the MaxiSys pro go to information and
communication page click and on your far right top corner you will see IC-instrument
cluster click on it and see if you will find what your looking for there. I myself I haven't
used that feature but i will be looking at it. Good luck.

Hi Arnel
I have checked this provision using an S500 2009 model 221.171and i did see any
provision using the MaxiSys pro where you can disable the buzzer. I will research more
to this issue and once again i will let you know.

Hi, this can adjusted through the instrument cluster. The vehicle is in a winter setting for when winter tyres are fitted. Adam

 No need a scanner to do this.Go to the instrument cluster on the car and factory re-setting hold for 3sec R baton on the dash scroll down and set .
