Volvo recommends that P3-1220 Symbol AUTO in light switch module mode is used when the car is driven.

Warning

The car's audio system is not able to determine when daylight is too weak or sufficiently strong, e.g. in fog and rain, in all situations.

The driver is always responsible for ensuring that the car is driven with a beam pattern suitable for the traffic situation and in accordance with applicable traffic regulations.

Display and instrument lighting

Different display and instrument lighting is switched on depending on key position; see Key positions - functions at different levels.

The display lighting is automatically subdued in darkness - the sensitivity is set with the thumbwheel.

The intensity of the instrument lighting is adjusted with the thumbwheel.

Headlamp levelling

The load in the car changes the vertical alignment of the headlamp beam, which could dazzle oncoming motorists. Avoid this by adjusting the height of the beam. Lower the beam if the car is heavily laden.

Leave the engine running, or have the car's electrical system in key position I.

Roll the thumbwheel up/down to raise/lower beam alignment.

Cars with active Xenon headlamps* have automatic headlamp levelling and are therefore not equipped with the thumbwheel.
