Lane departure warning system
System which, using a camera which
recognises solid or broken lines, detects the
involuntary crossing of longitudinal traffic lane
markings on the ground.
To provide safe driving, the camera analyses
the image then, if the driver's attention drops,
triggers a warning if the vehicle drifts over a
lane marking (speed higher than 50 mph
(80 km/h)).
This system is particularly useful on motor ways
and main roads.
Activation
F Press this button, the indicator lamp comes on.
The lane departure warning system
cannot, in any circumstances replace
the need for vigilance on the part of the
driver.
deactivation
You are warned by the vibration of the driver's
seat cushion:
-
o
n the right-hand side, if the marking on
the ground has been crossed on the right,
-
o
n the left-hand side, if the marking on the
ground has been crossed on the left.
No warning is transmitted while the direction
indicator is active and for approximately
20 seconds after the direction indicator is
switched
off.
detection - Alert Operating fault
The detection may be impeded:
-
i f the markings on the ground are
worn,
-
i
f there is little contrast between the
markings on the ground and the
road surface,
-
i
f the windscreen is dirty,
-
i
n certain severe weather
conditions: fog, heavy rain, snow,
bright sunlight or direct exposure
to the sun (low sun, leaving a
tunnel,
...) and shade.
F
P
ress this button again, the
indicator lamp goes off. In the event of a fault, the indicator lamp in the
button flashes.
Contact a CITROËN dealer or a qualified
workshop.
The status of the system remains in the
memory when the ignition is switched off. It is necessary to observe the driving
regulations and to take a break every
two hours.

difference of less than 6 mph (10 km/h),
-
w
hen a vehicle overtakes you with a speed
difference of less than 15 mph (25 km/h),
-
t
he traffic must be flowing normally,
-
i
n the case of an overtaking manoeuvre,
if this is prolonged and the vehicle being
overtaken remains in the blind spot,
-
y
ou are driving on a straight or slightly
curved road,
-
y
our vehicle is not pulling a trailer, a
caravan... No alert will be given in the following situations:

(parked vehicles, barriers, street lamps,
road signs...),

very long vehicle (lorry, coach...) which is
at the same time detected at the rear in the
blind spot angle and present in the driver's
forward field of vision,

-
d
irectional headlamps for improved
visibility when cornering.
Additional lighting
Other lamps are installed to fulfil the
requirements of particular driving conditions:
-
r
ear foglamps to better signal the presence
of the vehicle in foggy conditions,
-
f
ront foglamps for better visibility in foggy
conditions and to improve lighting at
intersections and when parking,
-
d
aytime running lamps for better visibility of
the vehicle by day.
Lighting function settings

situations, the power of their beams
may dazzle other drivers. They should
only be used in fog or falling snow.
In these weather conditions, you should
switch on the foglamps and dipped
beam headlamps manually, as the
sunshine sensor may detect sufficient
light.
Do not forget to switch off the front and
rear foglamps when they are no longer
necessary.

Switching off the lighting
when switching off the ignition
When the ignition is switched off, all of the
lamps switch off immediately, 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 sur face of the
glass of the headlamps and rear lamps
is normal; it disappears after the lamps
have been on for a few minutes.
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 manually 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 energy economy mode).
daytime running lamps /

When a low level of ambient light is detected
by a sunshine sensor, the number plate
lamps, sidelamps 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 brightness returns to a sufficient
level or after the windscreen wipers are switched
off, the lamps are switched off automatically.

light the dipped beams headlamps come on
automatically when the ignition is switched off.
Operating fault
In the event of a malfunction of the
sunshine sensor, the lighting comes

in the instrument panel and/or a
message appears in the screen,
accompanied by an audible signal.
In fog or snow, the sunshine sensor
may detect sufficient light. In this
case, the lighting will not come on
automatically.
Do not cover the sunshine sensor,
coupled with the rain sensor and
located in the centre of the windscreen
behind the rear view mirror; the
associated functions would no longer
be controlled.
