If you pop the bonnet and look at the top of your headlights, you should see the letters U - D (Up & down) and L - R (Left & Right) with arrows showing which way to turn to adjust. You should then see little slots where you can put a long philips screw driver in to turn the dials. The one just behind the high beam adjusts the light Up and down. The one towards the side fender adjusts it left and right.
The little metal thing is what the slots should lead your screwdriver to, the head of the screwdriver will meet with the teeth of the metal thing and you just turn to adjust.
