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.

Driving
the whole manoeuvre, in particular using the
mirrors.
Radar
The operation of the radar as well as the
associated functions may be impaired through
the accumulation of dirt (mud, frost, etc.), in
certain difficult weather conditions (very heavy
rain, snow) or if the bumper is damaged.
If the front bumper is to be repainted, contact
a CITROËN dealer or a qualified workshop;
certain types of paint could interfere with the
operation of the radar.
Driving aids camera
This camera and its associated functions
may be impaired or not work if the windscreen
area in front of the camera is dirty, misty,
frosty, covered with snow, damaged or
masked by a sticker.
In humid and cold weather, demist the
windscreen regularly.
Poor visibility (inadequate street lighting,
heavy rain, thick fog, snowfall), dazzle
(headlamps of an oncoming vehicle, low sun,
reflections on a damp road, leaving a tunnel,
alternating shade and light) can also impair
detection performance.
In the event of a windscreen replacement,
contact a CITROËN dealer or a qualified
workshop to recalibrate the camera;
otherwise, the operation of the associated
driving aids may be disrupted.
Other cameras
The images from the camera(s)
displayed on the touch screen or on the
instrument panel may be distorted by the
relief.
In the presence of areas in shade, or in
conditions of bright sunlight or inadequate
lighting, the image may be darkened and with
lower contrast.
Obstacles may appear further away than they
actually are.
Sensors
The operation of the sensors as well as
the associated functions may be disturbed
by sound interference such as that emitted
by noisy vehicles and machinery (e.g. lorries,
pneumatic drills), by the accumulation of
snow or dead leaves on the road or in the
event of damaged bumpers and mirrors.
When reverse gear is engaged, an audible
signal (long beep) indicates that the sensors
may be dirty.
A front or rear impact to the vehicle can
upset the sensors’ settings, which is not
always detected by the system: distance
measurements may be distorted.
The sensors do not systematically detect
obstacles that are too low (pavements, studs)
or too thin (trees, posts, wire fences).
Certain obstacles located in the sensors’ blind
spots may not be detected or may no longer
be detected during the manoeuvre.
Certain materials (fabrics) absorb sound
waves: pedestrians may not be detected.
Maintenance
Clean the bumpers and door mirrors and
the field of vision of the cameras regularly.
When washing your vehicle at high pressure,
direct the spray from at least 30 cm away
from the radar, sensors and cameras.
Mats
The use of mats not approved by
CITROËN may interfere with the operation of
the speed limiter or cruise control.
To avoid any risk of jamming the pedals:
► ensure that the mat is secured correctly,
► never fit one mat on top of another.
Units of speed
Ensure that the units of speed displayed
on the instrument panel (mph or km/h) are
those for the country you are driving in.
If this is not the case, when the vehicle is
stationary, set the display to the required
units of speed so that it complies with what is
authorised locally.
In case of doubt, contact a CITROËN dealer
or a qualified workshop.
Speed Limit recognition
and recommendation
Refer to the General recommendations on the
use of driving and manoeuvring aids .
Using the camera located at the top of the
windscreen, this system detects the following
types of signs and displays the corresponding
information on the instrument panel:
– the maximum authorised speed,
– no overtaking,
– the end of the previous limitations /
restrictions.

Driving
6Operation
The system starts automatically when moving
off.
A check of the operating conditions takes place: these two indicator
lamps come on in the instrument panel.
When these conditions are met, these two
indicator lamps go off. The system is activated.
If the operating conditions are not met, the
system is activated but is no longer effective.
This is signalled by the fixed illumination of these
two warning lamps in the instrument panel.
Operating conditions
Once engaged, the system is active only when
these operating conditions are met:
– The vehicle is moving forwards.
– No malfunction of the vehicle is detected.
– The speed of the vehicle is equal to or greater
than approximately 37 mph (60 km/h).
– The longitudinal marking of the traffic lanes is
clearly visible.
– The visibility conditions are clear.
– The trajectory is in a straight line (or in the
case of bends, they are wide).
– The field of vision is sufficiently clear (the
safety distance with the vehicle ahead is
respected).
– In the event of a lane departure, the direction
indicator corresponding to the direction (right or
left) of the departure has not been operated. –
The trajectory of the vehicle is consistent with
the road layout.
Deactivation / Reactivation
► Press this button to deactivate / reactivate the
function.
Deactivation is signalled by the illumination of
the button indicator lamp.
Upon reactivation, the two instrument panel
indicator lamps remain lit and fixed until the
speed reaches 37 mph (60 km/h).
The state of the system stays in the memory
when switching off the ignition.
Detection
If a deviation in direction is detected on
the left or the right, the indicator lamp on
the corresponding side flashes in the instrument
panel, accompanied by an audible signal.
No warning is transmitted while the direction
indicator is activated and for approximately 20
seconds after the direction indicator is switched
off.
A warning may be transmitted if a direction
marking (arrow) or non-standard marking
(graffiti) is crossed.
The detection may be impeded: – if the markings on the road are worn,
– if there is little contrast between the
markings on the road and the road surface.
The system is automatically deactivated if the Stop & Start function is active. The
system will restart and re-enable recognition
of the operating conditions after the vehicle is
started.
The system may suffer interference or not work correctly:
– when the vehicle is carrying an excessive
load (even more so if it is poorly balanced);
– under poor visibility conditions (rain, fog,
snow, etc.);
– under poor light conditions (dazzling
sunlight, darkness, etc.);
– if the windscreen is dirty or damaged near
the camera;
– if the ABS, DSC, ASR or Intelligent Traction
Control systems are out of order.
Malfunction
When a malfunction occurs, this warning
lamp lights up, accompanied by an
