There's probably an official way, but you might be lucky enough to push a
screwdriver between the bonnet and the top of the grille. There a three
cross-head screws holding the grille to the car. Remove these, pop the
grille off and then using some long nose pliers, open then inside the bonnet
latch mechanism - if all goes well, the bonnet will pop up.

Good luck,
