headlight adjustment
Proper adjustment of the headlights of the Transporter T4 is important both for road safety and for driving comfort at night, especially when driving on the highway.
The direction of the flow of light from the headlights should provide illumination of a sufficiently long section of the roadway, but not blind the drivers of oncoming vehicles. Accurate, “by science”, headlight adjustment is possible only with the help of special devices. Therefore, the following describes where the adjusting elements are located and the conditions for adjusting. Tires must be inflated with air at normal pressure.
The car must be loaded with only 75 kg (weight of one person) located on the driver's seat.
The fuel tank must be filled.
Park the vehicle on a level, preferably level ground.
Push the front of the car hard down a few times so that the front wheel suspension springs are firmly in their working position.
After that, roll the car a few meters. Set the headlight range adjustment knob to "O".
The headlights are adjusted only in low beam mode. The size of the deviation of the optical axis of the main headlights is 12 cm at a distance of 10 m, and fog lights at the same distance - 20 cm. See fig. 525 and 528.
