Lighting and visibility
4Automatic illumination of headlamps
If your vehicle is fitted with this function, the
dipped beam headlamps are switched on
automatically if the light is poor.
In fog or snow, the sunshine sensor may
detect sufficient light. In this case, the
lighting will not come on automatically. If
necessary, you must switch on the dipped
beam headlamps manually.
They are switched off when the light returns
to a sufficient level.
Do not cover the sunshine sensor at the top
centre of the windscreen.
You can adjust the sensitivity of the sunshine sensor.
For more information on Vehicle
configuration , refer to the corresponding
section.
Activation
► Turn the ring to this position.
The lamps go out automatically when the ignition
is switched off.
Guide-me-home lighting
If your vehicle is equipped: when you leave your
vehicle, the dipped beam headlamps remain on
for the selected period of time (e.g. leaving a car
park).
With the ignition off or the
key in the STOP position
► Within 2 minutes of switching off the engine,
turn the ignition key to the STOP position or
remove the key.
► Pull the lighting control stalk towards the
steering wheel.
This indicator lamp lights up on the
dashboard.
Each action on the lighting control stalk, pulled
towards the steering wheel, extends the
guide-me-home lighting by 30 seconds up to
approximately 3 minutes. Once this time has
elapsed, the lamps go out automatically.
Deactivate this control by holding the control
stalk pulled towards the steering wheel for more
than 2 seconds.
Automatic headlamps
System which automatically changes to main
beam according to the ambient light level and
the driving conditions, using a camera located at
the top of the windscreen.
This system is a driving aid. The driver remains responsible for
the vehicle's lighting, its correct use for the
prevailing conditions of light, visibility and
traffic, and observation of driving regulations.
Activation
► Turn the lighting control stalk ring to
this position.
► Set the function by pressing the
MODE button: select "ON" in the
"Automatic main beam" menu.
For more information on Vehicle
configuration , refer to the corresponding
section.
► Flash the headlamps (going beyond the point
of resistance) to activate the function.
Operation

48
Lighting and visibility
Once the function is activated, the system
operates as follows:
If the brightness is sufficient and/or if the traffic
conditions do not allow illumination of the main
beam headlamps:
– The dipped beam headlamps will
remain on: this indicator lamp lights up on
the instrument panel.
If the brightness is very low and the traffic
conditions allow:
– The main beam headlamps
come on automatically: these
indicator lamps light up on the instrument panel.
If the situation requires a change of headlamp
beam, the driver can take over at any time.
Flashing the headlamps again pauses the
function and the lighting system changes to
"automatic illumination of headlamps" mode.
At a speed lower than approximately 9 mph (15
km/h), the function deactivates automatically.
If the main beam headlamps are still needed,
flash the headlamps again; the main beam
headlamps then remain on fixed until the vehicle
reaches a speed of approximately 25 mph (40
km/h).
Above 25 mph (40 km/h), the function is
reactivated automatically (provided that you have
not flashed the headlamps again to turn off the
main beam headlamps during this interval).
Deactivation
► Turn the lighting control stalk ring to
the "Dipped beam" position.
The system may suffer interference or not work correctly:
– under conditions of poor visibility (falling
snow, heavy rain or thick fog, etc.),
– if the windscreen in front of the camera is
dirty, misted or obscured (by a sticker, etc.),
– if the vehicle is facing highly reflective
signs.
The system is not able to detect: – road users that do not have their own
lighting, such as pedestrians,
– vehicles whose lighting is obscured, such
as when running behind a safety barrier on a
motorway, for example,
– vehicles at the top or bottom of a steep
slope, on twisty roads, on crossroads.
Parking lamps
This system allows you to leave the lamps on
when parked; with the ignition off, and the key in
the STOP position or removed.


► Move the lighting control stalk ring to position
O, then to dipped beam headlamps or main
beam headlamps.
This indicator lamp comes on in the
dashboard.
The lamps will stay on for the duration of your
parking.
Extended lighting can significantly reduce
the vehicle's battery charge.
Headlamp beam height
adjustment
To avoid inconvenience to other road users,
the height of the halogen headlamps should be
adjusted according to the load in the vehicle.
This function can be accessed in dipped beam
and main beam headlamp positions.


Successive presses on these
controls adjust the headlamps.
An indicator lamp on the display indicates the
selected setting position (0, 1, 2, 3).

Safety
5General safety
recommendations
Do not remove the labels attached in
different places on your vehicle. They
include safety warnings as well as
identification information for the vehicle.
For all work on your vehicle, use a
qualified workshop that has the technical
information, skills and equipment required, all
of which a CITROËN dealer is able to
provide.
Depending on country regulations,
certain safety equipment may be
mandatory: high visibility safety vests,
warning triangles, breathalysers, spare bulbs,
spare fuses, fire extinguisher, first aid kit, mud
flaps at the rear of the vehicle, etc.
Installing electrical accessories:
– The fitting of electrical equipment or
accessories not approved by CITROËN may
cause excessive current consumption and
faults and failures with the electrical system
of your vehicle. Contact a CITROËN dealer
for information on the range of approved
accessories.
– As a safety measure, access to the
diagnostic socket, used for the vehicle's
electronic systems, is reserved strictly for
CITROËN dealers or qualified workshops,
equipped with the special tools required (risk
of malfunctions of the vehicle's electronic
systems that could cause breakdowns or
serious accidents). The Manufacturer cannot
be held responsible if this advice is not
followed.
– Any modification or adaptation not intended
or authorised by CITROËN or carried out
without meeting the technical requirements
defined by the Manufacturer will result in the
suspension of the commercial warranty.
Installation of accessory radio
communication transmitters
Before installing a radio communication
transmitter with an external aerial, you must
without fail contact a CITROËN dealer for
the specification of transmitters which can
be fitted (frequency, maximum power, aerial
position, specific installation requirements),
in line with the Vehicle Electromagnetic
Compatibility Directive (2004/104/EC).
Declarations of conformity for radio
equipment
The relevant certificates are available on the
http://service.citroen.com/ACddb/ website.

Safety
Dynamic stability control
(DSC)
Switching on
The DSC system is activated automatically every
time the vehicle is started.
It comes into operation in the event of a grip or
trajectory problem.
This is indicated by the flashing of this warning lamp on the instrument panel.
Deactivation
This system cannot be deactivated by the driver.
Malfunction
The lighting of this warning lamp, accompanied by an audible signal and
confirmed by a message on the instrument panel
display, indicates a malfunction of the DSC
system.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Anti-slip regulation (ASR)
Deactivation / Reactivation
The ASR system is activated automatically every
time the vehicle is started.
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
Electronic stability control
(ESC)
Electronic stability control (ESC: Electronic
Stability Control) integrating the following
systems:
– anti-lock braking system (ABS) and electronic
brake force distribution (EBFD),
– emergency braking assistance (EBA),
– wheel anti-slip regulation (ASR) or traction
control,
– dynamic stability control (DSC).
Definitions
Anti-lock braking system (ABS) and
Electronic brake force distribution
(EBFD)
This system improves the stability and handling
of your vehicle when braking and contributes
towards improved control on bends, in particular
on poor or slippery road surfaces.
ABS prevents wheel locking in the event of
emergency braking.
EBFD manages the braking pressure wheel by
wheel.
Emergency braking assistance (EBA)
In an emergency, this system enables you
to reach the optimum braking pressure more
quickly and therefore reduce the stopping
distance. It is triggered in relation to the speed at which
the brake pedal is depressed. The effect of this
is a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip, by acting on the brakes of the driving
wheels and on the engine. It also improves the
directional stability of the vehicle on acceleration.
Dynamic stability control (DSC)
If there is a difference between the path followed
by the vehicle and that required by the driver, the
DSC monitors each wheel and automatically acts
on the brake of one or more wheels and on the
engine to return the vehicle to the required path,
within the limits of the laws of physics.
Anti-lock braking system (ABS) and electronic brake
force distribution (EBD)
If this warning lamp comes on,
accompanied by an audible signal and a
message in an instrument panel screen, it
indicates a fault with the anti-lock braking system
(ABS) which could result in loss of control of the
vehicle when braking.
If these warning lamps come on,
accompanied by a message in the
instrument panel screen, it indicates a fault with
the electronic brake force distribution (EBFD)
system which could result in loss of control of the
vehicle when braking.
You must stop as soon as it is safe to do so.
In both cases, contact a CITROËN dealer or a
qualified workshop.
For maximum braking efficiency, a
bedding-in period of around 300 miles
(500 kilometres) is needed. During this
period, it is advisable to avoid any sudden,
repeated and prolonged braking.
The ABS does not provide shorter braking distances. On very slippery
surfaces (ice, oil, etc.) the ABS may extend
braking distances.
When changing wheels (tyres and rims),
ensure that these are approved for your
vehicle.
For emergency braking, press the
brake pedal very hard and do not
release it, even on a slipper surface; you
will then be able to continue steering the
vehicle to avoid an obstacle.
After an impact, have these systems checked by a CITROËN dealer or a
qualified workshop.

Safety
5Dynamic stability control
(DSC)
Switching on
The DSC system is activated automatically every
time the vehicle is started.
It comes into operation in the event of a grip or
trajectory problem.
This is indicated by the flashing of this warning lamp on the instrument panel.
Deactivation
This system cannot be deactivated by the driver.
Malfunction
The lighting of this warning lamp, accompanied by an audible signal and
confirmed by a message on the instrument panel
display, indicates a malfunction of the DSC
system.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Anti-slip regulation (ASR)
Deactivation / Reactivation
The ASR system is activated automatically every
time the vehicle is started.
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip.
Reactivate the system as soon as the level of
grip permits.



ASR

► Press this button to deactivate / reactivate the
function.
The illumination of the button indicator lamp,
accompanied by a message on the instrument
panel display screen, indicates that the ASR
system is deactivated.
The ASR system is automatically reactivated
every time the ignition is switched off
Malfunction
The lighting of this warning lamp, accompanied by an audible signal and
confirmed by a message on the instrument panel
display, indicates a malfunction of the ASR
system.
Have the system checked by a CITROËN dealer
or a qualified workshop.
ASR / DSC
These systems offer increased safety in
normal driving, but they should not encourage
the driver to take extra risks or drive at high
speed.
It is in conditions of reduced grip (rain, snow,
ice) that the risk of loss of grip increases. It
is therefore important for your safety to keep
these systems activated in all conditions, and
particularly in difficult conditions.
The correct operation of these systems
depends on observation of the manufacturer's
recommendations regarding as much
the wheels (tyres and rims), braking and
electronic components as the assembly and
repair procedures used by CITROËN dealers.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain neutral
behaviour on the road.
Intelligent Traction Control
Traction assistance system on roads with low
grip (snow, ice, mud, etc.).
This system makes it possible to detect the
situations of precarious grip which can make the
starting and the progress of the vehicle difficult.
In these situations, the Intelligent Traction
Control system overrides the ASR system by
transferring the driving force to the wheel with
the greatest contact with the ground to optimise
traction and trajectory tracking.

54
Safety
Engage a gear corresponding to the speed to
prevent the engine stalling.
► To manually deactivate the system, press the
button; the indicator lamp goes out.
The function may be unavailable if the brakes overheat. Wait a few minutes for
them to cool down before trying again.
Malfunction
When a malfunction of the Hill Assist
Descent Control system occurs, this
warning lamp lights up.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Seat belts
Inertia reel
The seat belts are equipped with an inertia reel
which allows the strap length to automatically
adjust to your shape. The seat belt returns to its
storage automatically when it is not used.
The inertia reels are fitted with a device which
automatically locks the strap in the event of a
collision, emergency braking or if the vehicle rolls
over. It can be released by pulling the strap firmly
and then releasing it so that it reels in slightly.
Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Activation/Deactivation
When starting the vehicle, this system is
deactivated.




► Press this button to activate/deactivate the
system.
When the button indicator lamp comes on, the
system is activated.
This system is active up to approximately 19
mph (30 km/h).
Above approximately 19 mph (30 km/h), the
system is automatically deactivated but the
button indicator lamp remains on.
The system is automatically reactivated as soon
as the speed returns below approximately 19
mph (30 km/h).
Malfunction
When a malfunction of the intelligent
traction control system occurs, this
warning lamp lights up.
Have the system checked by a CITROËN dealer
or a qualified workshop.
Load inertia control
The actual total weight of a commercial vehicle
can vary considerably depending on its load.
The centre of gravity of the vehicle can therefore
move in the longitudinal direction and even in
height.
Each of these variations has repercussions
on braking, traction, cornering behaviour and
overturning.
The load inertia control estimates the actual total
weight of the vehicle by analysing its behaviour,
during acceleration and braking phases.
This system then adapts the intervention of the
DSC and ASR systems according to the weight
distribution of the vehicle. In critical situations,
your vehicle therefore remains more safely on its
trajectory.
Hill Assist Descent
Control
Descent assistance system on roads with low
grip (mud, gravel, etc.) or with a steep gradient.
This system reduces the risk of the vehicle
slipping or running out of control as it moves
downhill.
It maintains the vehicle at a constant speed
during a descent by acting independently and
differentially on the brakes.
Activation / Deactivation
When starting the vehicle, the system is
deactivated.




► With the speed below 19 mph (30 km/h),
press this button to activate the system; the
button indicator lamp lights up.
When the vehicle begins its descent, you can
release the accelerator and brake pedals; the
button indicator lamp flashes.
The brake lamps automatically light up when the
function is activated.
If the speed exceeds 19 mph (30 km/h), the
system is automatically deactivated but the
button indicator lamp remains on.
The system is automatically reactivated as soon
as the speed returns below 19 mph (30 km/h).
You can depress the accelerator or brake pedal again at any time.
For the system to activate, the slope
must be greater than 8%.
Do not use the system with the gearbox in
neutral.
