i have a print out from galaxy owners site,there is an allen key headed adjuster at the back of each Xenon lamp which moves the head light to a flat beam suitable for use on either side of the road so you can do it before you go .As Lutz says the headlamp adjustment is critical but you dont have to move this,mine was out anyway and was adjusted at MOT the auto adjustment keeps it to this setting but mine was a little high.Try logging on as it is full of useful info anyway but if you cant then i will type the instructions in here or you
