Headlight Beam Adjustment

CAUTION:

Turn off the light before adjusting the headlight beam level. If it is necessary to inspect the beam level, do not keep the light on for two minutes or more.
When blocking the light emitted from the headlight, use a light shield or equivalent. Do not apply the tape on the lens or place the cloth over it. It may raise the temperature in the light and cause deformation/bubble formations of the plastic lens.

Before checking the headlight beam level, be sure of the following:
- Check the area around the headlight for any scratches, damage or other type of deformation.
- The vehicle is parked on a level surface.
- The inflation pressure of tires is correct.
- The vehicle does not have load.
- Vehicle's fuel tank is fully filled.
Set the headlight beam leveler switch to "0" position. (Model with manual leveler)
Bounce the vehicle several times to normalize the suspension.
Make certain that someone is seated in the driver's seat.
Measure the distance between the low beam bulb centers and the height of the bulb center.
