On the SLK you only have to push the hood up. You can do it with one hand.

he wants it at 90 degrees straight up

Tried before without success, mine is R 172 ( thought I'd damage something)

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 .

On the 170 you just have to push. I am sure. no levers.

I think the r170 has the button to push on the strut to raise it straight up

for r170

Changing your own hood shock or strut is a great and easy way to get started on DIY, or "Do It Yourself" projects. It should take you less than 30 minutes to replace the shock and you could save over a hundred dollars from what a shop might charge. The only thing you really need to worry about is you will need to have a friend hold the hood up or brace the hood in the up position something sturdy. The hood is surprisingly heavy and you do not want it falling on you when you are working.

Begin by raising the hood to the full up and locked, or service position. If the shock is worn out you will need to brace it securely or have someone hold it up for you.

Something to keep in mind then. I can't work on the engine but I often check oil, water, brake fluid, electrical and driving belt.
That's the only thing I can.

I'm not too good at posting links - try this from a previous posting - it refers to accessing the battery but the pic shows that the bonnet / hood is open fully.

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.
