How to open engine bay MERCEDES 17 ton Class 2

How do you open the engine bay on mercedes 17 ton class 2 ?

Most of the class 2 i have driven so far just flip up from the bottom but I was in a 17 ton merc and had no idea how to open it.

Sorry the question is a bit vague

It’s only a half bonnet and you can’t see anything other than the oil filler cap when you do. All your checks are conducted by the computer when you turn the ignition on.

cat remember if there is but
It’ll be a choice .

A push up knob button at the bottom of the Grill

b A pull leaver inside the cab drivers side like in a car / could be in the door frame like Scania did

c there aint one

Sorry long time since i did a MAN

Should be 2 lift up catches each end of the front grill slats to release the bonnet.

No catches on my old 58 plate Axor. Just give the grille a good pull!!
