Adjusting the headlights on a Toyota 4Runner is a straightforward task, but it does require some precision to make sure the lights are aimed correctly for optimal visibility and to avoid blinding other drivers.

Note: Make sure the gas tank is full, tires are properly inflated and vehicle has no heavy loads.

Tools you will need: 25-Feet Tape Measure, Carpenter’s Tape and a Flat Screwdriver

Steps:

Park your vehicle on a level surface. Make sure you park on a flat, level surface facing a wall. Front bumper is at least 25 feet away from the wall. Turn off the engine, but leave the lights on to low beam mode.

Locate the centerpoint of the headlights. Usually a tiny circle or square-shaped mark on the center indicates the centerpoint of the headlight.

Measure centerpoint height. Measure the height from ground to centerpoint of the headlight.

Centerpoint height to wall. Measure the same height on the wall and mark it with a carpenter’s tape.

Adjusting the headlights. Locate the vertical adjustment screw which is usually located on the headlight assembly. This will allow you to raise (counterclockwise) or lower (clockwise) the headlight beam. The top of the light beam should be aimed on the top of the tape on the wall.
