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.

Pyrotechnic pretensioning
This system improves safety in the event of a
frontal or side impact.
Depending on the severity of the impact, the
pyrotechnic pretensioning system instantly
tightens the seat belts against the body of the
occupants.
The pyrotechnic pretensioning seat belts are
enabled when the ignition is on.
Force limiter
This system reduces the pressure of the seat
belt on the chest of the occupant, thus improving
their protection.
In the event of an impact
Depending on the nature and
seriousness of the impacts, the pyrotechnic
device may trigger before and independently
of airbag deployment. Deployment of the
pretensioners is accompanied by a slight
discharge of harmless smoke and a noise,
due to the activation of the pyrotechnic
cartridge incorporated in the system.
In all cases, the airbag warning lamp comes
on.
Following an impact, have the seat belt
system checked, and if necessary replaced,
by a CITROËN dealer or a qualified
workshop.
Front seat belts
The driver's seat is fitted with a pyrotechnic
pretensioner and a force limiter.
On versions with a front passenger airbag, the
passenger's seat is also fitted with a pyrotechnic
pretensioner and a force limiter.
The front bench seat is fitted with two seat belts.
If you install a front bench seat as an
accessory, it must be fitted with approved
seat belts.
Seat belts not fastened warning lamp
When the vehicle is started, this warning
lamp comes on, accompanied by an
increasing audible signal, if the driver and/or the
front passenger has not fastened their seat belt.
This alert works equally well for versions with an
individual passenger front seat as for versions
with a two-seat front bench seat.
Height adjustment

► On the driver's side or the side passenger
seat side, squeeze the control with the belt

Driving
Driving recommendations
► Observe the driving regulations and remain
vigilant whatever the traffic conditions.
► Monitor your environment and keep your
hands on the wheel to be able to react to
anything that may happen any time.
► Drive smoothly, anticipate the need for
braking and maintain a longer safety distance,
especially in bad weather.
► Stop the vehicle to carry out operations that
require close attention (such as adjustments).
► During long trips, take a break every two
hours.
Important!
Never leave the engine running in a
closed space without sufficient
ventilation. Internal combustion engines emit
toxic exhaust gases such as carbon
monoxide. Danger of poisoning and death!
In severe wintry conditions (temperature
below -23°C), let the engine run for 4
minutes before moving off, to ensure the
correct operation and durability of the
mechanical components of your vehicle
(engine and gearbox).
Never drive with the parking brake
applied . Risk of overheating and
damage to the braking system!
Do not park the vehicle or leave the
engine running on a flammable
surface (dry grass, dead leaves, etc.). The
exhaust system of your vehicle is very hot,
even several minutes after the engine stops.
Risk of fire!
Never leave a vehicle unattended with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P (depending on the
type of gearbox).
Never leave children inside the vehicle
unsupervised.
To assure the durability of your vehicle and your safety, remember that certain precautions,
described hereafter, should be taken when
driving your vehicle :
Manoeuvre cautiously, at low speed
The dimensions of your vehicle differ from those
of a light vehicle, in width, in height, as well as in
length, and some obstacles will be more difficult
to notice.
Manoeuvre slowly.
Before turning, check that there are no obstacles
at mid-height along the sides.
Before reversing, check that there are no
obstacles, particularly at high level behind the
vehicle. Be aware of the external dimensions, if ladders
are fitted.
Load the vehicle correctly
With a load carried, the vehicle must remain
within the maximum authorised weight, the
Gross Vehicle Weight.
To avoid upsetting the balance of the vehicle,
the load should be centred and the heaviest part
placed on the floor in front of the rear wheels.
It is inadvisable to place heavy loads on a roof
rack.
Loading also implies adherence to the maximum
load of the roof bar anchor points. Adhere to
the maximum permissible weight, according to
CITROËN dealer specifications.
Loads must be securely lashed down.
A load that is not properly secured inside the
vehicle may affect vehicle handling and create a
risk of accident.
If your vehicle is fitted with a drop-side back, the
height and width of the load must remain within
the overall dimensions of the vehicle.
Drive the vehicle in a prudent and efficient
way
Take corners gently.
Anticipate the need to brake as the stopping
distance is increased, particularly on wet or icy
roads.
Be aware of the effect of side winds on the
vehicle.
Effective eco-driving saves fuel; accelerate
progressively, anticipate the need to slow down
and adapt your speed to suit the situation.
Indicate changes of direction well in advance so
that you are seen by other road users.
Take care
The tyres must be inflated to at least the
pressures indicated on the label, even over-
inflated by 0.2 to 0.3 bar for long journeys.
On flooded roads
We strongly advise against driving on flooded
roads, as this could cause serious damage to
the engine or gearbox, as well as to the electrical
systems of your vehicle.


If you are obliged to drive on a flooded road:
► check that the depth of water does not
exceed 15 cm, taking account of waves that
might be generated by other users,
► deactivate the Stop & Start function,
► drive as slowly as possible without stalling. In
all cases, do not exceed 6 mph (10 km/h),
► do not stop and do not switch off the engine.

Driving
Brakes
Braking distances are increased when towing a
trailer. To avoid overheating of the brakes, the
use of engine braking is recommended.
Side wind
Bear in mind the increased susceptibility to the
wind that the vehicle will have.
Anti-theft protection
Electronic immobiliser
The keys contain an electronic immobiliser
device.
This device locks the engine supply system. It
activates automatically when the key is removed
from the ignition.
When the ignition switch is turned on, a dialogue
is set up between the key and the electronic
immobiliser.
This warning lamp goes off after the key has been recognised, the ignition is
switched on and the engine can be started.
If the key is not recognised, the engine
cannot be started. Use another key and
have the faulty key checked by a CITROËN
dealer.
Carefully note the key number. In case of
loss, the intervention of a CITROËN
dealer will be faster and more efficient if you
provide this number and the confidential card.
Do not make any modifications to the
electronic immobiliser system.
Operating the remote control, even in your
pocket, may cause the doors to be unlocked
accidentally.
The simultaneous use of other high-frequency
devices (mobile phones, home alarms, etc.),
may temporarily disturb the operation of the
remote control.
Except for reinitialisation, the remote control
cannot operate while the key is in the ignition
switch, even when the ignition is off.
Driving with the doors locked could make
it more difficult for the emergency
services to enter the vehicle in an emergency.
As a safety precaution (with children on
board), remove the key from the ignition when
leaving the vehicle, even for a short time.
When purchasing a second-hand
vehicle:
– check that you are in possession of the
confidential card,
– have the keys memorised by a CITROËN
dealer, to be sure that the keys in your
possession are the only ones that allow the
vehicle to be started.
Confidential card

It is given to you upon delivery of your vehicle
with the duplicate key.
It contains the identification code required for
any intervention by a CITROËN dealer on the
electronic engine immobiliser system. This code
is hidden by a film, which is to be removed only
when necessary.
Keep your card in a safe place, never inside the
vehicle.
When undertaking a long trip or journey
however, it is advisable to take this card with you
along with your personal papers.
