HID or Stock?
STOCK.
Make sure the fuel tank is at least half full, then park the vehicle on a level surface about 6 inches from a vertical surface -- the driveway and garage door often work well for this. Turn on the low beams and mark the center of the "hot spot" from each headlight with a masking tape "+" on the wall or door. Back the vehicle straight back about 25 feet, and check where the hot spot from each headlight now falls. They should be about 2 inches below and 2 inches to the right of each "+" on the wall. Adjust accordingly.
HID: same procedure.. but aim about 1-2" lower.
Also you will need a torx bit (T5 or T7 dont remember which size).
