My SL600 did that a few times I would have to pull over get out and shut the trunk lid again. Do NOT slam it with a lot of force!! This will almost surely crack your third brake light, which will cost about $150 for a new one and is not a fun job to replace. But you can try closing it with a little weight, that helped mine to realize that it was closed. Once I replaced my third brake light which was slightly cracked when i got the car, I decided not to haul cargo in the trunk and didn't mind since that wasn't what I got the car for anyway. I have other cars for hauling things. But, you can try closing the trunk manually using your weight a bit. just don't slam it.... good luck. If that doesn't work, then maybe replace that switch that tells the car the trunk is shut, don't know the part number or cost...

My 07 SL550 the soft close works, when you click the trunk lid shut a motor pulls it down the last inch or so. But to open it, you click the latch at the back of the car to open the trunk and the lid is very heavy and takes a lot of effort to lift it open. Obviously something is wrong. What could it be? It's like you're lifting against a hydraulic mechanism that doesn't want you to open it. I don't care to fix it if it's going to cost a lot because I don't use my R230's to haul anything; I have a GL450 SUV for carrying groceries or whatever else might fit in there, and also have an S550 with a massively huge trunk, and that car's trunk lid operates perfectly. Closes at the push of a button. My SL600, that car's trunk lid does not fight you when opening but doesn't pull itself shut at the end when closing, has to be closed manually for the entire operation. So, neither of my R230's trunk lids are working the way they were intended! LOL
Both vario roofs work well though.
