Maintenance and care Headlamp aiming • Your vehicle is equipped with headlamps designed to meet Visual aim requirements according to FMVSS 108, table 17Ć2. • Your headlamps are marked VOL [visual/optical (aiming) left]. This means that the left side of the light patterns for each low beam headlamp is used to aim the lamp (Fig. 1). • Each headlamp may be properly aimed in the vertical (up/down) direction only. The horizontal (left/right) aim is preset by the headlamp manufacturer and does not need to be reĆaimed. • Turning the headlamp adjusting screws V1 and V2 in the directions indicated by the embedded arrows (Fig. 2) represents a change in vertical aim direction. Turn clockwise for up and counterĆ clockwise for down. It is important that both adjusting screws are turned by an equal number of revolutions or parts of revolutions and are turned as well in the same direction. Turn V1 before V2. Never V2 before V1. Failing this requirement leads to improperly aimed headlamps and may cause glare light for oncoming drivers. For example, if one of your low beam headlamps is aimed too low, you will turn V1 and V2 clockwise an equal number of revolutions until correct aim is achieved.
