Question about Cars & Trucks
The short answer is you do not and mostly don't need to. It is a lifetime fluid. There isn't even a dipstick to check the level. This is after all a well engineered German Machine unlike any Domestic or Asian Go cart that passes for an auto these days. The long answer is you can either go to a competent independent shop or dealer to have them check and add fluid; or for the mechanically inclined you can try it yourself. You have to make sure the transmission is at operating temperature (but not too hot, about 90-100F). There is a Allen head socket bolt on the bottom or side of the transmission pan depending on the transmission you have. Some have both and only one is right so make sure its the right one. Most are on the bottom which doesn't seem right because you would think the fluid would just pour out, but it doesn't because there is an internal funnel. The one on the side is actually the drain. So, remove the lower bolt, (trust me) then you have to pump the fluid from the bottle through a tube into the pan. The pumps are sold at every auto parts store. When the fluid begins to overflow the hole, then the level is good. Just put the plug back in and your done. There it wasn't easy, but no one said it would be. That's why they don't mention how to do this in the owner's manual, they dot expect the owner to do it. Oh, yes, one more thing, put in the correct fluid or the transmission is unlikely to survive for long. You generally can't use off the shelf oil, except for one and only one brand. It is Valvoline in the red bottle which specifically states for BMW and Mercedes. Its expensive 5-8$ per quart but until recently we were paying 26$ a quart for the ESSO brand the dealer sells. Do NOT use anything else or the transmission life will be measured in weeks. Trust me.

SOURCE: Where do I add the
The fill drain plug I believe is on the left side of the transmission about 1in above where the oil pan bolts on. I think it is a 7mm allen bolt.If you are topping off the fluid make sure to check the fluid level at the fill hole while the engine temp is still cold. It should trickle out while the engine is in park and running. Make sure to tighten to spec and use approved oil. There should be a label on the transmission pan itself listing the part number for the fluid to use.

Either hook the jumper cables to the battery in the trunk or hook the postive to the postive stud under the hood( passenger side near the firewall) and the ground to the block.

On the driver side of the transmission pan there is a fill plug. The car must be in the air and level. With the car running fluid will run out of the plug hole when it is full. This is no fun without a lift.
