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.

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.
