CITROEN DS5 Owner's Handbook Manual page 143

Lighting left on audible
signal
An audible signal when a front door
is opened warns the driver that the
vehicle's exterior lighting is on, with the
ignition off and in manual lighting mode.
In this case, switching off the lighting
stops the audible signal.
With the ignition off, if the dipped
headlamps remain on, the vehicle goes
into "ECO" mode to avoid discharging
the battery.
The lighting goes off when you switch
off the ignition, but you can always
switch it on again using the lighting
control stalk.
In some weather conditions (e.g. low
temperature or humidity), the presence
of misting on the internal surface of the
glass of the headlamps and rear lamps
is normal; it disappears after the lamps
have been on for a few minutes.
Daytime running lamps
(LEDs)
They come on when the engine is started.
Depending on the country of sale or where
required by regulations, they are used for:
- daytime running lamps in day mode and
sidelamps in night mode (they are brighter
when daytime running lamps),
or
- sidelamps in day and night mode.
