Waiting for the answer.
Where are the jump start terminals under the hood on a 2003 e320
If not under the hood or in the trunk it will be located under the back seat passenger side
Under the dash just to the left of the steering wheel. It is a red handle on 04s and 05s.
On my 1998 E320 there are 1. fuses left of the instrument cluster facing the door, 2. fuses near the battery, and 3, under the hood on the driver's side
after you open the inside hood release there is a little black piece of plastic in the grill push it to the left or right or you may have to pull it straight out different years did it different.
Under the driver's side dashboard, just to the right of the hood release lever. It is covered by a hinged plastic door.
The hood release on my 1998 E320 wagon is under the dash next to the drivers door. It is also listed in the Owner's Manual.
On my 2003 e320 it is located just below the steering wheel, on the panel by your knees. It is red!

Open the hood, get to the back of the light, remove the rubber cover and the light is visible. Turn the light bulb housing and pull the bulb out. Installing is the reverse.
