2012 E350 cabriolet tire pressure and USB port

My newly acquired 2012 E350 cabriolet calls for front tire pressure of 35 PSI and back at 36 PSI per sticker on fuel door. That provides a pretty hard ride, particularly at lower speeds on city streets. Any suggestions?

Also, I seem to get no power from the USB port in the center console to charge my iPhone. Dealer claims it is problem with phone but both Apple store and Best Buy have said there is no setting on phone to correct this, that power cord is OK, therefore I have concluded problem is in USB female port in console. I cannot find fuse for this port and so far dealer insists problem is not within car. Any ideas? Thanks.

Does the USB port recognize a USB drive plugged into it with a few MP3s? If so, then the dealer is likely correct.

The USB port probably doesn't supply enough power to make the iPhone happy. You'll probably need a high powered USB cig lighter adapter to charge.

If the USB port fails to recognize the USB drive with media on it then the port may have failed. This is assuming your car works like my 2014 C300 w/ Comand.

Thank you for the answer on the USB report. I'll take it to the dealer and see if that helps them.
