How do you open the front hood on your 1999 ML320?

Check for a hood release down by your feet when you get in the car. I believe this one is bit hidden from view but it should be down at the bottom of your dashboard. It may look like a handle or a ring. It just needs a little tug and you should hear a pop of your hood. Now go to the hood and feel around the newly created finger width opening and there should be a lever to push up a bit and the release should give way for you to open the hood the rest of the way.

Actuallly it is true you must pull the inside release by your left knee, but then you must go to the front grill where the large Mercedes emblem is. Put your hand inside the emblem and you will find your hood latch!!! I too had that problem when I bought mine. ;-)
