Are you sure your car hasn't got the auto-level mechanism? This is generaly the case if you have the HID light option. These types have a self-leveling mechanism, located at the rear wheels. I believe a dash warning light should warn, when this mechanism fails. Check this first pls.
In case you have standard lighting, there's also a manual levelknob in the car. There should be two knobs available near the bulbs. If I recall correct, the one closest adjust height, the other sideways.
Fog lights are not required to see the mainbeam, as they beam under fog-particles. However, some 'adjust' them to fill the gap between headlights and car, but you should def. be able to see a beam on the road from the main headlights.
