I'm driving a 2009 ML-500 and it works fine for me but something is going weird while using the cruise control feature...
whenever the speed is under 120 Km/h I can set the cruise control to the speed I like either above, below or equal to the current speed just 'til I reach the limit of 120 where the alarm of the "maximum speed reached" starts to beep... From now 'til I disable the cruise control by moving the CC stick forward or pressing the brake I won't be able to activate or control my speed unless I get back to the 120 KM/H....

You can imagine how annoying it is to drive on the high ways at the speed of 140-150 KM/H and for any reason,I have to press the brakes to get lower than 120 KM so I can re-activate the cruise control again...

I dunno what's wrong as I'm sure this is not normal... can you suggest what should I do order to solve it ?

 

Any suggestion ?!!

 

Read this PDF and see if you can get anything out of it. See if you can cancel Distronic for the time being.

 

Please UPDATE YOUR PROFILE in USER CP to include the year of your ML and where you live.

 

Done ! Just for the record my car is ML500 - 2009 and I'm living in Dubai

thx in advance

 

Hey, I wanted to ask you did you fix your problem because I have the exact same problem with my car and it’s so annoying
