I remember that from the previous post, someone asked dealer how to do reset service indicator and they did not answer. Actually I found that there is an official video how to do this in MBUSA website.

There are many useful videos there.
Okay, after I watched one of videos, I have a question about Pre-safe function. They say this function will change the front seat positions automatically in a way that the damage is minimized. However, to do this, the passenger seats memory have to be installed.

Now, my question is that if the driver seat only has the memory function and the passenger seat does not have it, Pre-safe functions only apply to the driver seat?
If so, the memory function for both front seats must be the standard option. As we know, for 2012 ML, this option is included in the pre-wire entertainment option, but for 2013 they did separate the option.
