Displays
The indicator in the instrument cluster confirms that the selected lighting is on.
A lamp fault is indicated by this warning light staying on, together with a message and an audible signal.
Rear fog light
They only work when the dipped or main beam headlights are on.

► Turn the ring forwards / backwards to switch them on / off.
When the lights switch off automatically ("AUTO" position), the fog lamps and dipped beam headlights stay on.
Front fog lamps / Rear fog lamps
They work with the parking, dipped or main beam lights on.

► Turn the ring forwards:
- once to switch on the front fog lamps,
- a second time to switch on the rear fog lamps.
► Proceed in the reverse order to switch off.
When the lights switch off automatically ("AUTO" position) or when the dipped beam headlights are switched off manually, the fog lamps and parking lights stay on.
► Turn the ring backwards to switch off the fog lamps; the parking lights will then switch off.
In clear or rainy weather, day or night, do not switch on the fog lamps. In these conditions, the power of their beams may dazzle other drivers. They must be used only in fog or snowfall (regulations may vary by country).
Do not forget to switch off the fog lamps as soon as they are no longer needed.
Lights on after switching off the ignition
To reactivate the lighting control, turn the ring to the "AUTO" position, then to the desired position.
When the driver's door is opened, a temporary audible signal reminds you that the lights are on.
They will switch off automatically after a time that depends on the battery charge state (energy-saving mode).
Lights off when switching off the ignition
When the ignition is switched off, all lights switch off immediately, except the dipped beam headlights if automatic follow-me-home lighting is activated.
Under certain climatic conditions (low temperature, humidity), condensation may appear on the inner surface of the front headlamp and rear lamp lenses; this is normal and disappears a few minutes after the lights are switched on.
Never look closely at the light beam of LED lamps - Risk of serious eye injury!

Travelling abroad
To drive in a country where the side of traffic is different from that of the vehicle's country of sale, adjust the dipped beam headlamp setting so as not to dazzle oncoming drivers. Consult a CITROËN dealer or a qualified workshop.
Daytime running lights / Position lights
These LED lights switch on automatically when the engine starts, at the front and at the rear.
They perform the following functions:
- Daytime running lights (lighting control in the "AUTO" position with sufficient brightness).
- Position lights (lighting control in the "AUTO" position with low brightness, or "Position lights only" or "Dipped / main beam headlights").
