LIGHTING CONTROLS
System for selection and control of the
various front and rear lamps providing
the vehicle's lighting.
Main lighting

The various front and rear lamps of the
vehicle are designed to adapt the driv-
er's visibility progressively according to
the climatic conditions:


- sidelamps, to be seen,

- dipped beam headlamps to see
without dazzling other drivers,

- main beam headlamps to see clearly
when the road is clear.



Additional lighting

Other lamps are installed to fulfi l the
requirements of particular driving con-
ditions:


- rear foglamps,

- front fog lamps with static intersec-
tion lighting,

- directional headlamps for improved
visibility when cornering,

- daytime running lamps to be more
visible during the day,

- guide-me-home and welcome light-
ing to facilitate access to the vehicle,

- parking lamps as vehicle position
markers.



Programming

Various automatic lighting control
modes are also available depending on
whether the following options are fi tted:


- guide-me-home lighting,

- welcome lighting,

- daytime running lamps,

- directional lighting,

- automatic illumination of headlamps.

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

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).

TYRE UNDER-INFLATION DETECTION
System which automatically and continu-
ously checks the pressure of the tyres
while driving.
Sensors fi tted in each valve trigger a
warning in the event of problem (speed
above 12 mph (20 km/h)).
This warning lamp is displayed
on the instrument panel and/or a
message appears in the screen,
accompanied by an audible signal,
to identify the wheel concerned.

Under-infl ated tyre
The STOP
warning lamp
comes on and/or this warn-
ing lamp is displayed on the
instrument panel, accompa-
nied by an audible signal and
a message in the screen iden-
tifying the wheel concerned.


)
Stop as soon as it is safe to do so,
avoiding any sudden movement of
the steering wheel and the brakes.

)
Repair or change the damaged
wheel (punctured or very defl ated
tyre), and have the tyre pressure
checked as soon as possible.

Puncture

Sensor(s) not detected or faulty
A message appears in the screen, ac-
companied by an audible signal, to
identify the wheel or wheels which are
not detected or to indicate a malfunc-
tion in the system.
Contact a CITROËN dealer or a quali-
fi ed workshop to replace the faulty
sensor(s).
This message is also displayed
when one of the wheels is away
from the vehicle (being repaired)
or when one or more wheels
without a sensor are fi tted.
If your vehicle is equipped with
a spare wheel, this is not fi tted
with a sensor. All repairs and changing of tyres
on a wheel fi tted with this sys-
tem must be carried out by a
CITROËN dealer or a qualifi ed
workshop.
If, when changing a tyre, you
install a wheel which is not de-
tected by your vehicle (example:
fi tting of snow tyres), you must
have the system reinitialised by
a CITROËN dealer or a qualifi ed
workshop.
The tyre under-infl ation detec-
tion system is an aid to driving
which does not replace the need
for the driver to be vigilant or to
drive responsibly. This system does not avoid the
need to have the tyre pressures
checked regularly (refer to the
"Identifi cation markings" sec-
tion) to ensure that the optimum
dynamic performance of the ve-
hicle is maintained and prevent
premature wear of the tyres, par-
ticularly in arduous driving condi-
tions (heavy load, high speed).
The tyre pressures must be
checked cold, at least once a
month. Remember to check the
pressure of the spare wheel.
The tyre under-infl ation detec-
tion system may experience
temporary interference due to
electro-magnetic emissions on a
frequency close to that used by
the system.


)
Check the tyre pressures as soon
as possible.
This check must be carried out when
the tyres are cold.
