Does any one know how to adjust the headlights on a 2011 GS350 with AFS? The left (driver) side is lower than the right (passenger) side quite a bit. Is it normal for the left side to be lower than the right? I see a silver adjusting screw at the back of the light and tried to turn it (clockwise) to raise it up with no result. The bubble doesn't move at all. What did I do wrong? Any help is greatly appreciated.
