As above: Keyhole in the grille that your ignition key fits unless it's jammed solid with road crud & salt. Turn it one way to 'pop' the bonnet & the other to release it, lifting it as you do so.
At the top of the plastic grille there's a key hole. Etcetera!
Ford seem to enjoy their strange bonnet releases these days. The focus has a keyhole behind the blue oval. Bizarro
