Air outlet
Press this control to activate
extraction of air to the outside; the
LED comes on. Press again to
switch off.
Air intake
Pressing this control activates the
exterior air intake into the passenger
compartment; the LED comes on.
Press again to switch off.
Additional heating
systems
Additional heating
This is passenger compartment heating,
additional to the standard equipment.
It can operate independently of the engine.
Additional heater or
programmable additional
heating
This is an additional, programmable and
separate system which heats the Diesel engine
hot coolant loop to make starting easier.
It improves the demisting and defrosting
per formance and that of the heated seats, if
fitted to the vehicle.
Automatic additional
heating
This is an additional system which starts
automatically when the ignition is switched
on. Its activation depends on the exterior
temperature and the temperature inside the
vehicle.
It switches off automatically once the heating
system is started manually. The passenger compartment heating is brought
up to temperature more rapidly.
This system must be programmed to start up
before you enter the vehicle.
Supplementary heating
On the 2-3 seats model, this is located under
t he seat on the driver's side with air diffusion
directed forwards.
On the 5 -9
seats model, it is
located at the rear. Depending
on the model, the air diffusion
is either direct from the rear
or comes from the rail located
under each of the two rows of
seats.
F

P
ress this control to activate/
deactivate the heating. The
LED comes on if the heating is
activated.
When rapid demisting and defrosting is
required, switch off the control.
Rear heating and/or air
conditioning
If your vehicle is fitted with an additional air
conditioning unit, located in the rear of the
vehicle: the distribution rail located in the
roof and the individual diffusion vents provide
a
per fect diffusion of cold air.

Hazard warning lamps
Visual warning by means of the direction
indicators to alert other road users to a vehicle
breakdown, towing or accident.
F

P
ress this button, the direction indicators
flash.
This can operate with the ignition off.
Electronic stability control
(ESC)
Electronic stability control (ESC) integrating the
following systems:
-

a
nti-lock braking system (ABS) and
electronic brake force distribution (EBFD),
-
em

ergency braking assistance (EBA),
-

w
heel anti-slip regulation (ASR) or traction
control,
-
d

ynamic stability control (DSC).

F Press the central part of the steering wheel.
Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking
and contributes towards improved control on
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
(EBFD) manages the braking pressure wheel
by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system permits the
optimum braking pressure to be reached
more quickly, therefore reducing the stopping
distance.
It is triggered in relation to 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.
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.
Safety

71
Intelligent Traction Control
System to improve traction on slippery sur faces
(snow, ice, mud, etc.)
This system checks for situations of difficult
sur face grip that could make it difficult to move
off or make progress.
In these situations, Intelligent Traction
Control takes over from the ASR system, by
transferring drive to the wheel with the best grip
on the ground to provide the best traction and
trajectory control.
Switching on
On starting the vehicle, this system is
deactivated.
F

P
ress this button to switch the system on;
the warning lamp in the button comes on.
This system is active up to about 19
mph
(30


km/h).
Once the speed exceeds 19
mph (30 km/h),
the system is deactivated automatically, but the
warning lamp in the button stays on. The system is reactivated automatically
as soon as the speed drops below 19
mph
(30

km/h).
Deactivation
F Press this button to deactivate the system;
the warning lamp in the button goes off and
the ASR system is active again.
Malfunction
If a fault occurs with the intelligent
t raction control, this warning lamp
comes on.
Have it checked by a
CITROËN dealer or by
a


qualified workshop.
Load inertia control
All such variations have an effect on braking,
traction, the behaviour of the vehicle when
cornering and the tendency to overturn.
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. 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 therefore remains more securely
on its intended trajectory.
Hill Descent Control
System that provides assistance when
descending on sur faces with poor grip (mud,
gravel, etc.) or on a
steep gradient.
This system reduces the risk of slip or loss of
control of the vehicle while descending a
hill.
It keeps the vehicle at a
steady speed during
a


descent by acting independently and with
varying force on each of the brakes.

Safety

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. Detection may be impeded:
-
i
f the markings on the road are worn,
-
i
f there is little contrast between the
markings on the road and the road
sur face.
The system may suffer inter ference or not
work correctly:
-
w
hen the vehicle is carrying a very
heavy load (even more so if the load is
not evenly spread),
-

w
hen the conditions of visibility are
poor (rain, fog, snow, etc.),
-

w
hen the lighting conditions are poor
(dazzling sun, shade, etc.),
-

i
f the windscreen is dirty or damaged
near the camera,
-

i
f any of the ABS, DSC, ASR or
Intelligent Traction Control systems are
out of service.
Malfunction
If a malfunction occurs, this warning
l amp comes on, accompanied by
an audible signal and confirmed by
a
message in the screen.
Have the system checked by a
CITROËN
dealer or a
qualified workshop.
