What light adjust buttons, can't even find those. Handbook is totally silent. Headlamps were OK on "0" but after first service the dash says they are now on "2" and they just point at the ground in front of the car, dangerousMy car has original Xenon projector lights that seem to be aimed too low for my taste. The light adjust buttons on the instrument panels don't seem to work. Is there a way to adjust the aim manually? I really need it to be aimed higher. please help.
