How to adjust the height of Audi headlights
Recently, the topic of Audi vehicle headlight adjustment has sparked heated discussions on major automotive forums and social media. Many car owners report that the illumination angle of the headlights is not good when driving at night, which affects driving safety. This article will introduce in detail the adjustment method of Audi headlight height, and attach relevant data for reference.
1. Why should we adjust the headlight height?
The correct headlight height ensures clear vision when driving at night and avoids glare to oncoming vehicles. According to traffic regulations, the irradiation range of headlights should be within a reasonable range.
| car model | Standard irradiation distance (meters) | regulatory requirements |
|---|---|---|
| Audi A4L | 50-70 | GB 4785-2019 |
| Audi Q5 | 60-80 | GB 4785-2019 |
| Audi A6L | 55-75 | GB 4785-2019 |
2. Steps to manually adjust the headlight height
1. Prepare tools: Phillips screwdriver, level, tape measure
2. Park the vehicle on flat ground, about 5 meters away from the wall
3. Turn on the headlights and observe the position where the light shines
4. Locate the adjustment screw on the rear of the headlight (usually marked "UP/DOWN")
5. Use a screwdriver to slowly rotate the adjustment screw and observe the light changes.
6. After adjusting to the appropriate height, test the actual driving effect.
| Adjustment direction | Screw rotation direction | light changes |
|---|---|---|
| rise | clockwise | Move the irradiation point upward |
| lower | Counterclockwise | Move the irradiation point downward |
3. Description of automatic adjustment system
Some new Audi models are equipped with an automatic headlight height adjustment system, which works as follows:
1. The system monitors the vehicle attitude through the body height sensor
2. Automatically adjust the headlight angle according to the load condition and road gradient.
3. No manual intervention required to ensure optimal lighting effects
| System type | Applicable models | Adjustment accuracy |
|---|---|---|
| dynamic steering lighting | A8L/Q7 etc. | ±0.5° |
| Basic automatic adjustment | A4L/A6L etc. | ±1° |
4. Frequently Asked Questions
Q: What should I do if the lighting is still not ideal after adjustment?
A: It is recommended to go to a 4S store for professional calibration, which may require the use of special equipment.
Q: How to adjust the headlight height on rainy days?
A: On rainy days, the road surface is highly reflective. You can lower the headlight height appropriately to avoid glare.
Q: Do I need to readjust the headlights after modification?
A: It must be readjusted. The modified headlight’s lighting position is different from the original one.
5. Safety tips
1. Please wear goggles when adjusting and avoid looking directly into strong light.
2. It is recommended that two people cooperate with the operation, one to adjust and the other to observe.
3. Be sure to conduct a road test after completing the adjustment.
4. If you are not sure how to operate, it is recommended to seek professional help.
Through the above detailed introduction, I believe you already know how to correctly adjust the headlight height of your Audi vehicle. Reasonable headlight settings can not only improve night driving safety, but also reflect civilized driving qualities. It is recommended that car owners regularly check the angle of headlight illumination to ensure driving safety.
