Note: It is very important that the headlights are installed correctly. Incorrect adjustment may result in blinding the driver of an oncoming vehicle or insufficient illumination of the roadway. Headlight beams should be adjusted every 12 months, when replacing bulbs or after any work on the front of the vehicle. Please note that the adjustment described below is only a temporary measure. Fine adjustment of headlights should be carried out at a specialized service station.
1. Each headlight has two adjustment screws. On the Probe model, these screws can only be accessed after removing the headlight trim (see Figure 14.4). On the Mazda MX-6 model, one of the screws is accessed from the rear of the headlight, and the second one is accessed from the front. In the Mazda 626 model, the adjusting screws are located on the top (figure 15.1).
2. The Mazda 626 model is equipped with a headlight adjustment device. If the direction of the headlights remains unsatisfactory after adjustment, this may be due to damage to the front of the body. Headlight adjustment is described below.
3. For adjustment you will need a level surface and a vertical wall. Place the car perpendicular to the wall. Draw a vertical line on the wall that goes through the center of the car and vertical lines that go through the centers of the headlights (figure 15.3).
4. Draw a horizontal line on the wall, the height of which is equal to the height of the centers of the headlights above the floor.
Note: To make it easier to mark the wall, park the car as close to the wall as possible.
5. Park the vehicle at a distance of B meters from the wall and make sure that the fuel tank is half full and there are no foreign objects in the vehicle.
6. Turn on the low beam headlights. The maximum brightness zone should be located 5 cm below and 5 cm to the right of the headlight centers. The headlights are adjusted by turning the adjusting screws. When the screw is turned clockwise, the headlight rises, and when it is turned counterclockwise, it falls. The headlight is adjusted horizontally in a similar manner.
7. Turn on the high beam headlights. The area of maximum brightness should be located directly below the horizontal line passing through the centers of the headlights.
Note: You may not be able to adjust both the low beam and high beam headlights at the same time. In this case, you should adjust the low beam more carefully, since it is used much more frequently and is more important for traffic safety.
8. After adjustment, try to contact the service station as soon as possible to perform a fine adjustment.
