2005 E320 Consol between the seats buttons
 

Inside this console there are two buttons, one has a wrench symbol and the other a "i" symbol. My manual does not discuss their functions, does anyone know what they are for?

The buttons are for the Tele-Aid/Emergency Call system. The wrench button is for Roadside Assistance, the "i" button is for INFO. You probably don't have an active subscription for this service, but since your system is digital, your dealer can activate it for you. I'm not sure what the subscription will cost, but it's probably a couple hundred bucks per year.

Thanks for the info, we do not use this.

And it is in your manual: go to index and look up tele aid.
