ADDITIONAL HEATING SYSTEMS
Supplementary heating
On the 2-3 seats version, this is located
under the seat on the driver's side with air
diffusion directed forwards.
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 duct located in
the roof and the individual diffusion vents
provide a perfect diffusion of cold air.
The warm air diffused at the floor, from the
front air conditioning unit, is distributed at
the feet of the rear passengers of rows 2
and 3.
A warm air diffusion vent, located on the rear
left wheelarch, may complete the assembly
for the feet of the rear passengers of row 3.
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
performance and that of the heated seats, if
fitted to the vehicle.
The passenger compartment heating is
brought up to temperature more rapidly.
This system must be programmed to start up
before you enter the vehicle. On the 5-9 seats version, it is
located at the rear. Depending
on the model version, the air
diffusion is either direct from the
rear or comes from the rail located under
each of the two rows of seats.
Press this control to activate/
deactivate the heating. The LED
is on if the heating is activated.
When rapid demisting and
defrosting is required, switch off the control.

PROGRAMMABLE ADDITIONAL HEATING
If your vehicle is fitted with separate
programmable heating: it gradually brings
the engine up to a good temperature to
facilitate starting. An integrated clock permits programming of
its start time. The passenger compartment
will be heated more quickly. Heating cycle indicator lamp

Cancelling the programming
Press this button briefly to clear
the programmed start time.
The screen illumination and the
pre-selection number (e.g. 1) are
switched off.
Good practice
To avoid any risk of poisoning or
asphyxiation, the additional heating must
not be used, even for short periods, in
an enclosed space such as a garage or
workshop which is not fitted with an exhaust
gas extraction system.
The additional heating is supplied by the
vehicle's fuel tank.
Ensure that the fuel gauge indicator lamp is
not at reserve.
Always switch off the additional heating
when filling with fuel to avoid any risk of fire
or explosion.
Do not park the vehicle on an inflammable
surface (dry grass, dead leaves, paper…),
there is a risk of fire.
The temperature near the heater must not
exceed 120 °C. A temperature higher than
this (for example in the case of painting in
an oven) could damage the components of
the electronic circuits.
The additional heating system is fitted with
a temperature limiter which cuts off the
combustion in the event of overheating due
to a lack of coolant.
Top up the coolant, then press the
programme selection control before
switching the heating on again. Have the additional heating system
checked at least once a year at the
beginning of winter. Maintenance and
repairs should only be carried out by a
CITROËN dealer.
Use only genuine replacement parts.
Recalling one of the pre-selected start times
Press this button as many times
as necessary until the number
corresponding to the required
pre-selected start time (e.g. 2)
appears.
After ten seconds, the time is cleared but
remains stored for as long as the number
(e.g. 2) and the screen remain on.
Switching off the heating
Press this button.
The heating cycle indicator lamp
and the screen are switched off.
Two different types of equipment
The additional heating is separate and
programmable. Before you enter the vehicle,
it gradually increases the temperature of the
engine to make starting easier.
This also facilitates passenger compartment
heating, demisting and defrosting.
The additional passenger compartment
heating system supplements the
standard equipment. Its operation may be
independent of the engine.
Switching on of the heating may be
programmable.

Driving safely
TRAJECTORY CONTROL SYSTEMS
Switching off
This system cannot be deactivated by
the driver.
Dynamic stability control (DSC)
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.

Seat belts
CAB SEAT BELTS
The front seats are fitted with pre-tensioners
and force limiters.
The bench rear seat is fitted with two seat
belts.
If you install a bench seat after handover, it
must be fitted with seat belts.
REAR SEAT BELTS
The seats/bench seats are fitted with three-
point seat belts and inertia reels.
The centre seat has a seat belt guide and
inertia reel, solid with the seat back.
Height adjustment
Squeeze the control with the return and slide
the assembly on the driver's seat side and
on the side passenger seat side.
The height of the seat belt associated with
the centre seat cannot be adjusted.
Fastening
Pull the strap in front of you, with an even
movement, ensuring that it does not twist.
Secure the buckle in its housing.
Check that the seat belt is fastened securely
and that the automatic locking system is
operating correctly by pulling the strap
rapidly.
Unfastening
Press the "red" button on the buckle
housing, the seat belt rolls up automatically
but you are advised to guide it. As a safety precaution, these
operations should not be carried out
while the vehicle is moving.
Driver's seat belt not fastened warning lamp
CREW CAB
Each rear seat is fitted with a three-point
inertia reel seat belt.
Use the seat belt to restrain one person only
per seat.
If the driver's seat belt is unfastened,
START mode of Stop & Start will not be
invoked. Engine restarting is only possible
with the ignition key. When the vehicle is started, this warning
lamp comes on if the driver has not fastened
their seat belt.

Improved safety and security
Impact resistance
Your vehicle has been designed to limit
the forces on the passenger compartment
as much as possible in the event of a
collision, the engine compartment adopts
a progressive deformation structure and
the front doors have been reinforced to
contribute to the rigidity of the whole.
Anti-theft protection
Your vehicle, in the van version, comprises
two zones with separate locking: the cab
and the load space.
Depending on the way in which it is used,
this function provides increased protection
both for your personal belongings and for
your merchandise.
An exterior protection alarm with anti-tilt
detection is available (as standard or as an
option) in certain countries. Details of these functions are given
in the "Ready to go - Front and rear
doors" section.
