Switching off the lighting when
switching off the ignition
When the ignition is switched off,
all of the lamps switch off immedi-
ately, except for the dipped beam
headlamps if automatic guide-
me-home lighting is activated.
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

Daytime lighting, compulsory in certain
countries, which comes on automati-
cally when the engine is started making
the vehicle more visible to other users.
Manual guide-me-home lighting
Temporarily keeping the dipped beam
headlamps on after the vehicle's igni-
tion has been switched off makes the
driver's exit easier when the light is poor.

Switching on


)
With the ignition off, "fl ash" the
headlamps using the lighting stalk.

)
A further "headlamp fl ash" switches
the function off.


Switching off

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



This function is assured:


- in countries where it is imposed by
regulations,
by illumination of the dipped beam
headlamps with the sidelamps and
number plate lamps; this function
cannot be deactivated.

- for other countries where it is pro-
vided,
by the use of dedicated lamps; this
function can be activated or deac-
tivated via the vehicle confi guration
menu.


The instruments and controls (instru-
ment panel, multifunction screen, air
conditioning control panel, ...) are not
illuminated, except in night mode with
manual or automatic illumination of
headlamps.

Switching on the lighting
when switching on the ignition
To reactivate the lighting control stalk, turn the ring A
to position "0"
- lighting off, then to the position of
your choice.
If the lighting is switched on manu-
ally after switching off the ignition,
there is an audible signal when a
front door is opened to warn the
driver that they have forgotten to
switch off the vehicle's lighting, with
the ignition off.
They switch off automatically after a
period which depends on the state
of charge of the battery (entry to en-
ergy economy mode).

these components in accordance with
the Maintenance and Warranty Guide
and according to your engine.
Otherwise, have them checked by a
CITROËN dealer or a qualifi ed workshop.


Battery

The battery does not require
any maintenance.

However, check that the ter-
minals are clean and correctly
tightened, particularly in sum-
mer and winter.
When carrying out work on the battery,
refer to the "Practical information" sec-
tion for details of the precautions to be
taken before disconnecting the battery
and following its reconnection.

the engine oil is changed.
Refer to the Maintenance and
Warranty Guide for details of
the replacement interval for
this component.
Particle emission filter (Diesel)

According to your version of instrument
panel, the start of saturation of the par-
ticle emissions fi lter is indicated by:


- fi xed illumination of the par-
ticle emissions fi lter warning
lamp, accompanied by an au-
dible signal and a message
that there is a risk of blockage
of the particle emissions fi lter,






The presence of this label, in particular
with the Stop & Start system, indicates
the use of a specifi c 12 V lead-acid bat-
tery with special technology and speci-
fi cation, for which the involvement of a
CITROËN dealer or a qualifi ed work-
shop is required when replacing or dis-
connecting the battery.
Failure to observe this recommendation
may shorten the life of the battery.

Depending on the environment (e.g.
dusty atmosphere) and the use of the
vehicle (e.g. city driving), replace them
twice as often if necessary
(refer to
the "Engines" section).
A clogged passenger compartment fi l-
ter may have an adverse effect on the
performance of the air conditioning sys-
tem and generate undesirable odours.
As soon as the traffi c conditions per-
mit, regenerate the fi lter by driving at a
speed of at least 40 mph (60 km/h) until
the warning lamp goes off.
If the warning lamp stays on, refer to
the "Additive level" section.
Following prolonged operation
of the vehicle at very low speed
or at idle, you may, in excep-
tional circumstances, notice the
emission of water vapour at the
exhaust on acceleration. This
does not affect the behaviour of
the vehicle or the environment. or

-
temporary illumination of
the service warning lamp,
accompanied by an audible signal and a message that
there is a risk of blockage of
the particle emissions fi lter.
