No.. This is something related to the TeleAid system. if they works in your E430, when you press the "i" button you got some operator (via phone call) to help you with any "I"NFO, when you press the "wrench" button your call are re-directed to the Mercedes-Benz 24H Service center (if you need a tow or something like that).
This works when they are propperly programed and you have the phone service working too
Best look my friend
Also this buttns are located inside the little compartment in the center console, not in the IC
