Maintenance and care AIMING THE HEADLAMPS Your vehicle is equipped with a Vehicle Headlamp Aim Device (VHAD) on each headlamp body. Each headlamp may be properly aimed in the horizontal direction (left/right) and the vertical position (up/down). A non-zero bubble reading does not necessarily indicate out-of-aim headlamps. If your vehicle is not positioned on a level surface, the slope will be included in the level indicator. Therefore, vertical headlamp adjustment should be performed only when beam direction appears to be incorrect. The horizontal aim must be adjusted first. You will need one 4 mm wrench or socket to make the adjustments. If the vehicle has been in an accident, the vehicle's front structure should be properly aligned before aiming the headlamps. Horizontal aim adjustment 1. Park the vehicle on a level surface. 2. With the hood open, remove the protective cover, then locate the horizontal indicator and the adjusting screw. 3. Use a 4 mm wrench or socket to turn the horizontal adjusting screw until the end of the shaft within the clear tube lines up with the "0" reference mark on the indicator when viewed directly from above. 240 IN OUT
