If your vehicle is fitted with this camera, it is
located at the rear, next to the third brake
lamp.
It sends images to the screen installed
in the cab. This rear vision is an aid to
manoeuvring.
The reversing camera may be coupled with
rear parking sensors.Screen
The camera sends the images to a 5 inch
LCD colour screen. This screen is also
the one used by the touch screen audio-
telematic system.
Activation and deactivation of the system
is done in the settings menu of the touch
screen audio-telematic system.
Operation
The camera comes into operation when
reverse gear is engaged and remains active
up to approximately 9 mph (15 km/h). It is
deactivated above 11 mph (18 km/h).
The camera also comes on, with the vehicle
stationary, when the rear doors are opened.
Switching off
When a forward gear is engaged, the last
image remains displayed for approximately
5 seconds then switches off.
In the same way, the last image also
remains displayed, with the vehicle
stationary, when the rear doors are closed.
Good practice
With optimum vehicle conditions (position on
the road, loading level) the maximum area of
visibility covered by the camera has a field
depth approximately 3 m long and 5.5
m wide.
The area of visibility may vary depending on
the external weather conditions (brightness,
rain, snow, fog, ...), the load in the vehicle
and the position of the vehicle on the road.
When cleaning the camera and the screen,
avoid using a detergent or a tool which may
scratch the glass.
Use a non-abrasive cloth or a small brush.

If your vehicle is fitted with pneumatic
suspension, you can adjust the height of
the rear of the vehicle to make loading and
unloading easier.
The controls are located alongside the
steering wheel in a MO
d E control panel.
There is a nominal level as well as 6 height
adjustment levels, raising (from +1 to +3)
or lowering (from -1 to -3). The levels are
indicated in the instrument panel screen.
Manual adjustment of the loading

Automatic correction of loading
floor height
Above 12 mph (20 km/h), the system
automatically returns the rear height to its
nominal value.
Operating fault
If a fault occurs with the system,
this warning lamp comes on.
Good practice
Driving with the suspension set too high or
too low risks damaging components under
the body.
The height may be adjusted automatically to
take account of changes of temperature or
loading.
You must avoid using this control in the
following circumstances:
-

when working underneath the vehicle,
-


when changing a wheel,
-


when the vehicle is being transported by

lorry, train, ferry, boat, ...
To avoid damaging the vehicle or injuring
anyone, check that there is nothing or no
person that might be close to or come into
contact with the vehicle, before raising or
lowering the suspension.
Above 3 mph (5 km/h), the system
reactivates automatically.
Have the system checked by a
CITROËN
dealer or a qualified workshop.

Pull the lever up slightly and press the
button to lower the parking brake lever.In the exceptional case of use of the
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.

HOrn
Press the centre of the steering wheel.
Anti-lock braking system and
electronic brake force distribution
Linked systems which improve the stability
and manoeuvrability of your vehicle when
braking, in particular on poor or slippery
surfaces.
Operation
The anti-lock braking system comes into
operation automatically when there is a risk
of wheel lock.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal accompanied by some noise.
When braking in an emergency
, press
very firmly without releasing the
pressure.
Switching off
These systems cannot be deactivated by
the
driver.
BrAKInG ASSIStA nc E SYS t EMS
Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
-

anti-lock braking system (ABS),
-


electronic brake force distribution

(EBFD),
-

emergency braking assistance (EBA).

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.

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.
