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

Safety
5Airbags

The airbags have been designed to optimise the
safety of the occupants in the event of a serious
collision; they work in conjunction with the force
limiting seat belts.
In the event of a serious collision, electronic
detectors record and analyse any abrupt
deceleration of the vehicle:
– if there is a violent impact, the airbags deploy
instantly and help better protect occupants of the
vehicle; immediately after the impact, the airbags
deflate rapidly in order not to hinder the visibility
or the possible exit of the occupants.
– in the case of a minor or rear impact or in
certain rollover conditions, the airbags are not
deployed; the seat belt alone contributes towards
ensuring your protection in these situations.
The airbags do not operate when the
engine is not running.
This equipment will only deploy once. If a
second impact occurs (during the same or a
subsequent accident), the airbag will not be
deployed again.
Deployment of the airbags is
accompanied by a slight discharge of
smoke and a noise, resulting from activation
of the pyrotechnic charge incorporated in the
system.
Although this smoke is not harmful, sensitive
individuals may experience slight irritation.
The noise of the detonation may result in a
slight loss of hearing for a short time.
Front airbags
System that protects the driver and front
passenger(s) in the event of a serious front
impact, in order to limit the risk of head and
chest injury.
The driver's airbag is fitted in the centre of the
steering wheel; the front passenger(s) airbag is
fitted in the dashboard above the glove box.
Lateral airbags and curtain
airbags
If fitted to your vehicle, the lateral airbags are
built into the backrests of the front seats, on the
side by the door.
The curtain airbags are built into the pillars and
the upper passenger compartment area, in the
roof above the front seats.
They inflate between the occupant and the
window.
They deploy on one side only (the side where
the collision occurs).
Malfunction
If this warning lamp comes on, contact a
CITROËN dealer to have the system
checked.
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal upright sitting position.
Fasten the seat belt ensuring it is correctly
positioned and adjusted.
Do not leave anything between the occupants
and the airbags (a child, pet, object, etc.), nor
fix or attach anything close to or in the way of
the airbag release trajectory; this could cause
injuries during their deployment.
Never modify the original definition of your
vehicle, particularly in the area directly around
the airbags.
After an accident or if the vehicle has been
stolen, have the airbag systems checked.
All work on the airbag systems must only
be performed by a CITROËN dealer or a
qualified workshop.
Even if all of the precautions mentioned
are observed, a risk of injury or of minor
burns to the head, chest or arms cannot be
ruled out when an airbag is deployed. The
airbag inflates almost instantly (within a few
milliseconds) then deflates within the same

Safety
5Installing a booster seat
The chest part of the seat belt must be
positioned on the child's shoulder without
touching the neck.
Ensure that the lap part of the seat belt
passes correctly over the child's thighs.
Use a booster seat with backrest, equipped
with a belt guide at shoulder level.
Additional protections
To prevent accidental opening of the
doors and rear windows, use the "Child lock".
Take care not to open the rear windows by
more than one third.
To protect young children from the rays of the
sun, fit side blinds on the rear windows.
As a safety precaution, do not leave:
– a child alone and unattended in a vehicle,
– a child or an animal in a vehicle which is
exposed to the sun, with the windows closed,
– the keys within reach of children inside the
vehicle.
Child seat at the rear

"Forward facing" or "Rearward
facing"




► Move the vehicle's front seat forward and
straighten the backrest so that the legs of the
child in the "forward facing" child seat or the
"rearward facing" child seat itself do not touch
the vehicle's front seat.
► Verify that the backrest of the "forward facing"
child seat is as close as possible to the backrest
of the vehicle's rear seat, and is ideally in contact
with it.
Child seat at the front

► Adjust the front passenger seat to the
highest and intermediate longitudinal
position , with the backrest straightened.
"Forward facing"
You must leave the front passenger
airbag active.
"Rearward facing"
The front passenger airbag must be deactivated before installing a rearward
facing child seat. Otherwise, the child risks
being seriously injured or killed if the
airbag is deployed .


Warning label - Front passenger airbag
You must comply with the following instruction,
reminded by the warning label on both sides of
the passenger sun visor:
NEVER use a rearward facing child restraint
on a seat protected by an ACTIVE AIRBAG in
front of it, DEATH or SERIOUS INJURY to the
CHILD can occur.

Safety
"ISOFIX" mountings

If fitted on the vehicle, the regulation ISOFIX
mountings are identified by labels.
The mountings comprise three rings for each
seat:

Deactivating the front
passenger airbag


Passenger airbag OFF
To guarantee the safety of your child, the
front passenger airbag must be
deactivated when a "rear facing" child seat is
installed on the front passenger seat.
Otherwise, the child risks being seriously
injured or killed if the airbag is deployed.
Vehicles not equipped with a
deactivation control
Installing a “rear facing” child seat on the front
passenger seat or bench seat is expressly
prohibited! Doing so would expose the child to
the risk of death or serious injury in the event
of airbag deployment.
Deactivating / Reactivating the front
passenger airbag
► Press this button and then, in the
"Passenger airbag" menu, select "OFF" to
deactivate the airbag.
► Select “ON” to reactivate it.When the ignition is switched on, this
warning lamp comes on accompanied by
a message in the display screen to indicate the
deactivation.
For more information on Vehicle
configuration (MODE) , refer to the
corresponding section.
Depending on version, it can also be deactivated
or reactivated via the touch screen audio and
telematics system.
Locations for child seats secured using the seat belt
In accordance with European regulations, this table indicates the options for installing child seats secured using a seat belt and universally approved
according to the weight of the child and the seating position in the vehicle.

65
Driving
6Effective 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.
On leaving the flooded road, as soon as safety
conditions allow, make several light brake
applications to dry the brake discs and pads.
If in doubt about the state of your vehicle,
contact a CITROËN dealer or a qualified
workshop.
In case of towing
Driving with a trailer places greater
demands on the towing vehicle and
requires extra care from the driver.
Respect the maximum towable weights.
At altitude: reduce the maximum load by
10% per 1,000 metres of altitude; the density
of the air decreases with altitude and the
performance of the engine reduces.
New vehicle: do not pull a trailer before
having driven at least 620 miles (1,000
kilometres).
If the outside temperature is high, let the
engine idle for 1 to 2 minutes after the
vehicle comes to a stop, to help it to cool.
Before setting off
Nose weight
► Distribute the load in the trailer so that the
heaviest items are as close as possible to the
axle and the nose weight (at the point where it
joins your vehicle) approaches the maximum
permitted without exceeding it.
Tyres
► Check the tyre pressures of the towing
vehicle and of the trailer, observing the
recommended pressures.
Lighting
► Check the electrical signalling on the trailer
and the headlamp beam height of your vehicle.
If a genuine CITROËN towing device is
used, the rear parking sensors will be
deactivated automatically to avoid the audible
signal.
When driving
Cooling
Towing a trailer uphill increases the temperature
of the coolant. The maximum towable load
depends on the gradient and the exterior
temperature. The cooling capacity of the fan
does not increase with engine speed.
► Reduce speed and lower the engine speed,
so as to limit the heating-up.
In all cases, pay attention to the coolant
temperature.
If this warning lamp and the STOP
warning lamp come on, stop the vehicle
and switch off the engine as soon as possible.

66
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.
