parking brake when the vehicle is
moving, apply the brake by pulling gently
to avoid locking the rear wheels (risk of
skidding).
If the parking brake is still on or has not
been released properly, this is indicated
by this warning lamp which comes on in
the instrument panel.
When parking on a slope, direct your wheels towards
the pavement and pull the parking brake lever up.
There is no advantage in engaging a gear after
parking the vehicle, particularly if the vehicle is
loaded.
The hazard warning lamps should only
be used in dangerous situations, when
stopping in an emergency or when
driving in unusual conditions.

Good practice
The ABS system does not provide shorter
braking distances. On very slippery surfaces
(black ice, oil...) the ABS can extend braking
distances. For emergency braking, press the
brake pedal hard and do not release it, even
on a slipper surface; you will then be able to
steer the vehicle and avoid an obstacle.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.Emergency braking assistance
System which, in an emergency, enables
you to obtain the optimum braking pressure
more quickly, thus reducing the stopping
distance.
Operation
It is triggered by the speed at which the
brake pedal is pressed.
The effect of this is a reduction in the
resistance of the pedal and an increase in
braking efficiency.
Switching off
This system cannot be deactivated by
the driver.
Operating fault
If this warning lamp comes on,
accompanied by an audible signal
and a message in the instrument
panel screen, it indicates a fault with
the anti-lock braking system which could result in
loss of control of the vehicle when braking.
For maximum braking efficiency, a
bedding-in period of around 300 miles
(500 kilometres) is needed. During this
period it is recommended that you avoid
harsh, repeated or prolonged braking. If this warning lamp comes on,
together with the ABS warning
lamp, accompanied by a message
in the instrument panel screen,
it indicates a fault with the electronic brake
force distribution which could result in loss
of control of the vehicle when braking. When braking in an emergency, press
firmly without releasing the pressure.
You must stop as soon as it is safe to do so.
In either case, contact a CITROËN dealer or
a qualified workshop.

driver.
dynamic stability control
( d S c )
The electronic stability programme acts on
the brake of one or more wheels and on the
engine to keep the vehicle on the trajectory
required by the driver, within the limits of the
laws of physics.
With the DSC system, maintain course
without trying to countersteer.
Operation
The DSC system is activated automatically
each time the vehicle is started. Operating fault
Illumination of this warning lamp,
accompanied by an audible signal
and confirmed by a message
in the instrument panel screen,
indicates a fault with the DSC system.
Have it checked by a CITROËN dealer or a
qualified workshop. Operation
This system is activated automatically every
time the vehicle is started.
In the event of a problem of adhesion or
trajectory, this system comes into play.
Switching off
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow,
on soft ground...), it may be advisable to
deactivate the ASR system, so that the
wheels can spin freely and regain grip.
-

Press this button, located in the

middle of the dashboard, to deactivate
the
system.
Anti-slip regulation (ASr)
Anti-slip regulation (also known as traction
control) optimises traction, avoiding wheel
spin by acting on the brakes of the driving
wheels and the engine.
If the button's warning lamp comes
on, accompanied by a message in the
instrument panel screen, this indicates that
the ASR system is deactivated.
It comes into operation in the
event of a grip or trajectory
problem.
This is indicated by flashing of this warning
lamp in the instrument panel.

Press this button again to reactivate it

manually.
Operating fault
If this warning lamp comes on,


accompanied by an audible signal
and a message in the instrument
panel screen, this indicates a fault
with the ASR system.
Have it checked by a CITROËN dealer or a
qualified workshop. Good practice
The DSC and ASR systems offer exceptional
safety in normal driving, but this should not
encourage the driver to take extra risks or
drive at high speed.
The correct operation of these systems
depend on observation of the manufacturer's
recommendations regarding the wheels
(tyres and rims), the braking components,
the electronic components and assembly
and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a qualified
workshop.Load inertia control
The true total weight of a commercial vehicle
can vary considerably depending on the load
carried. As a result, the centre of gravity of
the vehicle can move, both longitudinally
and in height.
All such variations have an effect on braking,
traction, the behaviour of the vehicle when
cornering and the tendency to overturn.
Load inertia control estimates the true
total weight of the vehicle by analysing its
behaviour under acceleration and braking.
This system then adapts the operation of
the DSC and ASR systems according to the
weight distribution in the vehicle. In critical
situations, your vehicle than remains more
securely on its intended trajectory.

S YS t EM
System which detects the involuntary
crossing of longitudinal traffic lane markings
on the ground (continuous or discontinuous
line).
A camera, fitted at the top centre of the
windscreen monitors the road and detects
lane markings and the position of the vehicle
within them.
With the vehicle running at a speed higher
than 35 mph (60 km/h), it triggers a warning
if the vehicle drifts off line.
This system operates to its full potential in
particular when used on motorways and
main roads.
Operation
The system starts automatically when
moving off. Operating conditions
Once running, the system is only active
when the operating conditions are met:
-

The vehicle is moving forward.
-

No operating fault
is detected in the
vehicle.
-
The vehicle is moving at a speed of at

least 37 mph (60 km/h).
-
The longitudinal lane markings on the

ground are clearly visible.
-
The conditions of visibility are normal.
-

The vehicle is in a straight line trajectory

(or if cornering, the corners are of large
radius).
-

The field of vision is suf
ficiently clear
(the safe distance from the vehicle in
front is observed).
-

If a lane marking is crossed (when

changing lane for example), the
corresponding direction indicator (left or
right) for the manoeuvre, is not used.
-

The vehicle's trajectory matches the

lane markings on the road.
The lane departure warning system
cannot, in any circumstances, replace
the need for vigilance on the part of
the
driver.
If the windscreen is damaged, it is strongly
recommended that you go to a CITROËN
dealer or a qualified workshop for any
replacement or calibration of the camera.
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.

The status of the system remains in the
memory when the ignition is switched off. The system may suffer interference or
not work correctly:
-
When the vehicle is carrying a very

heavy load (even more so if the load is
not evenly spread).
-
When the conditions of visibility are poor

(rain, fog, snow, ...).
-
When the lighting conditions are poor

(dazzling sun, shade, ...).
-
If the windscreen is dirty or damaged

close to the camera.
-
If the
ABS, DSC, ASR or Intelligent
Traction Control systems are out of
service.
The system is automatically deactivated
if the Stop & Start system is active. The
system will restart and check the operating
conditions again when the vehicle moves off.

trAFFIc SIGn rEcOGnItIOn
This system is a driving aid that make
use of a camera located at the top of the
windscreen.
The camera detects the following types of
traffic signs and displays the corresponding
information in the instrument panel:
-
speed limits,
-


no overtaking.
The units for the speed limits (mph or


km/h) depend on the country you are
driving in.
It should be taken into account so that you
observe the speed limit.
For the system to operate correctly when
you change country, the units for speed in
the instrument panel must be those for the
country you are driving in. The automatic reading of traffic signs is
a driving assistance system and does
not always display speed limits correctly.
The speed limit signs present on the road
always take priority over the display by the
system.
The system cannot in any circumstances
replace the need for vigilance on the part of
the driver.
The driver must observe the driving
regulations and must adapt the speed of the
vehicle to suit the weather and traffic.
It is possible for the system to not display
the speed limit if it does not detect a speed
limit sign within a preset period.
The system is designed to detect signs that
conform to the Vienna Convention on traffic
signs. To maintain correct operation of the
system:
- Regularly clean the area in front of the
camera.
-

Do not carry out any repairs to the area

of the windscreen close to the camera
lens.
When replacing headlamp bulbs, you
are strongly recommended to fit genuine
replacement parts.
The use of other bulbs could reduce the
performance of the system.
