Headlamp height adjustment: load changes tilt

In a few sentences

In brief

Manual and automatic systems have different controls.

Useful to know

The load and inclination of the compartment change the direction of the headlights. HELLA distinguishes manual adjustment and automatic systems, including dynamic acceleration and braking reactions. [1]

Do not take the brief headlight movement at start as a complete test of correct setting. Basic regulation and automatic compensation are related but different tasks. When repairing, the specific performance and the required procedure must be established. The number button itself does not explain which setting is correct for each load; see vehicle directions.
