may not work on r172/newer cars
Tried before without success, mine is R 172 ( thought I'd damage something)On the SLK you only have to push the hood up. You ca do it with one hand.
Will have to investigate if there are any levers of the sort, I had 190 model which had these but did not seem to find anything similar on the R 172 .
It's the same on our SLK250. The front one is easy to see. The rear ones are more visible if you put the hood in "service" position - just keep pushing it open farther and it rests at a second, wider opening.
