Lighting and visibility
4Lighting control
Never look too closely at the luminous
beam of LED lamps: risk of serious eye
injury!
In some weather conditions (e.g. low
temperature or humidity), misting on the
internal surface of the glass of the headlamps
and rear lamps is normal, and will disappear
after the lamps have been on for a few
minutes.
Travelling abroad
Vehicles equipped with halogen
headlamps:
If planning to use your vehicle in a country
that drives on the other side of the road, the
headlamp dipped beams must be adjusted to
avoid dazzling oncoming drivers. Contact a
CITROËN dealer or a qualified workshop.
If one or more lamps fails, a message
asks you to check the lamp or lamps
concerned.

This is confirmed by an audible signal and the
lighting of the corresponding direction indicator
lamp on the instrument panel.
► To switch off the parking lamps, return the lighting control stalk to the central position.
Automatic illumination of
headlamps
When the ring is at the "AUTO" position and
a low level of ambient light is detected by a
sunshine sensor, the number plate lamps, side lamps and dipped beam headlamps are switched
on automatically, without any action on the
part of the driver. They can also come on if
rain is detected, at the same time as automatic
operation of the windscreen wipers.
As soon as the light returns to a sufficient level
or after the windscreen wipers are switched off,
the lamps are switched off automatically.
Operating fault
In the event of a malfunction of the sunshine sensor, the lighting comes on,
this warning lamp is displayed in the instrument
panel accompanied by an audible signal and/or a
message.
Contact a CITROËN dealer or a qualified
workshop.
They operate with the sidelamps or dipped beam headlamps on, in manual or
auto mode.
► Press and rotate the ring:– forwards a 1st time to switch on the front
foglamps.
– forwards a 2nd time to switch on the rear
foglamp.
– backwards a 1st time to switch off the rear
foglamp.
– backwards a 2nd time to switch off the front
foglamps.
When the lamps are switched off automatically
(with AUTO model) or when the dipped beam
headlamps are switched off manually, the
foglamps and sidelamps remain on.
► Rotate the ring backwards to switch the foglamps off; the sidelamps will then switch off.
In good or rainy weather, by day and
night, using the front and rear foglamps
is prohibited. In these situations, the power of
their beams may dazzle other drivers. They
should only be used in fog or falling snow.
In these weather conditions, it is your
responsibility to switch on the foglamps and
dipped beam headlamps manually as the
sunshine sensor may detect sufficient light.
Do not forget to turn off the front and rear
foglamps as soon as they are no longer
necessary.
Switching off of the lamps when the
ignition is switched off
When the ignition is switched off, all of the
lamps turn off immediately, except for dipped
beam headlamps if automatic guide-me-home
lighting is activated.
Switching on the lamps after
switching off the ignition
To reactivate the lighting control, rotate the
ring to the "AUTO" position, then to the
desired position.
If the driver's door is opened, a temporary
audible signal warns the driver that the lamps
are on.
They will go off automatically after a period of
time that depends on the state of charge of
the battery (entering energy economy mode).
Direction indicators

Automatic illumination of headlamps
When the ring is at the "AUTO" position and
a low level of ambient light is detected by a
sunshine sensor, the number plate lamps, side lamps and dipped beam headlamps are switched
on automatically, without any action on the
part of the driver. They can also come on if
rain is detected, at the same time as automatic
operation of the windscreen wipers.
As soon as the light returns to a sufficient level
or after the windscreen wipers are switched off,
the lamps are switched off automatically.

this warning lamp is displayed in the instrument
panel accompanied by an audible signal and/or a
message.
Contact a CITROËN dealer or a qualified
workshop.
Do not cover the sunshine sensor,
integrated with the rain sensor and
located at the top centre of the windscreen
behind the rear view mirror; the associated
functions would no longer be controlled.
In fog or snow, the sunshine sensor may
detect sufficient light. In this case, the
lighting will not come on automatically.
Daytime running lamps /
Sidelamps


The front and rear lamps light up automatically
when the engine starts.
They provide the following functions:
– Daytime running lamps (lighting control stalk
at position "AUTO" with adequate light level).
– Sidelamps (lighting control stalk in "AUTO"
position with low light level or "Sidelamps only”
or "Dipped/main beam headlamps").
In daytime running lamps mode, the
diodes are brighter.
Guide-me-home lighting
Automatic
With the "Automatic illumination of headlamps"
function activated (lighting control stalk at the
AUTO position), under low ambient light, the
dipped beam headlamps come on automatically
when the ignition is switched off.
Activation, deactivation and the duration of the
guide-me-home lighting are set in the vehicle
parameters menu.

Lighting and visibility
• If the "AUTO" and "Main beam" indicator lamps were on, the system changes to dipped beam.
To reactivate the system, flash the headlamps
again.
The system may be disrupted or not work correctly:
– When visibility conditions are poor (snowfall, heavy rain, etc.).– If the windscreen in front of the camera is dirty, misted or obscured (for example, by a
sticker).
– If the vehicle is facing highly reflective signs.
When the system detects thick fog, it
temporarily deactivates the function.
The system is not able to detect:
– Road users that do not have their own lighting, such as pedestrians.– Vehicles whose lighting is obscured (for example, vehicles driving behind a safety
barrier on a motorway).
– Vehicles at the top or bottom of a steep slope, on winding roads, on crossroads.
Clean the windscreen regularly,
particularly the area in front of the
camera.
The internal surface of the windscreen can
also become misted around the camera.
In humid and cold weather, demist the
windscreen regularly.

maximum authorised load
2. Driver only + maximum authorised load
Cornering lighting

If your vehicle is so equipped, this system
makes use of the beam from a front foglamp to
illuminate the inside of a bend, when the main or
dipped beam headlamps are on and the vehicle
speed is below 25 mph (40 km/h) (urban driving,
winding road, intersections, parking manoeuvres,
etc.).
