Exterior lighting controls

~5min read

Selection and control device for the various front and rear lights providing vehicle lighting.

Main lighting

The vehicle's various front and rear lights are designed to progressively adapt the driver's visibility to weather conditions:

  • position lamps, to be seen,
  • dipped headlamps, to see without dazzling other drivers,
  • main beam headlamps, to see well on clear roads.
Auxiliary lighting

Other lights are fitted to meet particular driving conditions:

  • a rear fog lamp, to be seen from a distance,
  • front fog lamps, to see even better,
  • cornering lamps, to see better through bends,
  • daytime running lights, to be seen in daylight.
Programming

Different automatic lighting control modes are also available according to the following options:

  • follow-me lighting,
  • automatic lighting,
  • cornering lighting.
Under certain climatic conditions (low temperature, humidity), condensation on the inner surface of the front headlamp and rear light lenses is normal; it disappears a few minutes after the lights are switched on. Manual controlsCommandes manuelles

Lighting controls are operated directly by the driver using ring A and stalk B.

In clear or rainy weather, day or night, switching on the front fog lamps and rear fog lamps is prohibited. In these situations, the power of their beams may dazzle other drivers. They must only be used in fog or snowfall. In these conditions, it is your responsibility to switch on the fog lamps and dipped headlamps manually, as the light sensor may detect sufficient light. Remember to switch off the front fog lamps and rear fog lamps as soon as they are no longer needed. Forgetting to switch off the lights

An audible warning sounds when a front door is opened, reminding the driver that the vehicle lights are still on. This applies when the ignition is off and the lights were switched on manually.

In this case, switching the lights off stops the audible warning.

With the ignition off, if the dipped headlamps remain on, they will switch off automatically after thirty minutes to avoid discharging the battery. Daytime running lights

System that switches on specific front lights so that the vehicle can be seen in daylight.

They switch on automatically and permanently, with the engine running, if:

  • The function is activated * in the "General Menu" of the instrument cluster screen.
  • The lighting control is in position 0 or AUTO.
  • All headlamps are off.

You can deactivate * the function in the "General Menu" of the instrument cluster screen.

Manual follow-me lighting

Temporarily keeping the dipped beams on after the vehicle is switched off makes it easier for the driver to leave in low light.

Activation
  • With the ignition off, perform a "headlamp flash" using the lighting control.
  • Another "headlamp flash" stops the function.
Off

The manual follow-me-home lighting switches off automatically after a set time.

Automatic lighting

The parking lights and dipped beams switch on automatically, without driver action, when low external light is detected or in certain cases when the wipers are operated.

When brightness has returned to a sufficient level or after the wipers stop, the lights switch off automatically.

Allumage automatique

Activation
  • Turn ring A to the "AUTO" position. Automatic lighting is accompanied by a message on the instrument cluster screen.
Off
  • Turn ring A to a position other than "AUTO".

    Switching off is accompanied by a message on the instrument cluster screen.

Associated with automatic follow-me lighting

Combined with automatic lighting, follow-me-home lighting offers the following additional options:

  • choice of the lighting duration: 15, 30 or 60 seconds, in the vehicle settings of the configuration menu on the instrument cluster screen,
  • automatic activation of follow-me-home lighting when automatic lighting is on.
Operating fault

If the light sensor malfunctions, the lights switch on, a message appears on the instrument cluster screen and an audible warning sounds.

Consult a CITROËN dealer.

In fog or snow, the light sensor may detect sufficient light, so the lights will not switch on automatically. Do not cover the light sensor, which is combined with the rain sensor and located in the middle of the windscreen behind the interior rear-view mirror; the associated functions would no longer be controlled.
