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.

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.
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.

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

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.

6Starting-switching off the
engine
Ignition switch

STOP position: Anti-theft.
The ignition is off.
MAR position: ignition on.
Certain accessories can be used.
AV V position: starter.
The starter is operated.
Avoid attaching heavy objects to the key or the remote control, which would weigh
down on its blade in the ignition switch and
could cause a malfunction.
Starting the engine
► With the parking brake applied and the
gearbox in neutral, turn the key to the MAR
position.
► Wait until this warning lamp goes out,
then operate the starter (AV V position)
until the engine starts.
The period of illumination of the warning lamp
depends on the climatic conditions.
When the engine is hot, the warning lamp lights
up for a few moments; you can start the engine
immediately.
► When the engine starts, release the key.
Immobiliser warning lamp
If this warning lamp lights up, change key
and have the faulty key checked by a CITROËN
dealer.
Switching off the engine
► Immobilise the vehicle.
► Move the key back to the STOP position.
In low temperatures
In mountainous and/or cold areas, it is
advisable to use a "winter" type fuel suited to
low or minus temperatures.
Battery standby system
If your vehicle is to be out of use for an extended
period of time, such as during winter storage for
example, it is strongly recommended to put the battery in standby mode in order to protect it and
optimise its life.


To put the battery in standby mode:
► Switch the engine off ( STOP position).


► Press the red button, then turn the key to the
BATT position.
The battery goes into standby mode
approximately 7 minutes later.
This time is necessary to:
– allow the user to leave the vehicle and lock the
doors using the remote control.
– ensure that all vehicle electrical systems are
deactivated.

68
Driving
When the battery is in standby mode,
access to the vehicle is only possible by
unlocking the mechanical lock on the driver's
side door.
After a battery standby, the information (time, date, radio stations, etc.) is
memorised.
To remove the battery from standby mode:
► Turn the key to the MAR - ON position.
► Start the vehicle normally ( AV V position).
Parking brake
Application
► Apply the parking brake to immobilise the
vehicle.
► Check that the parking brake is correctly
applied before leaving the vehicle.
Apply the parking brake only when the
vehicle is stationary.
When parking on a slope, turn your
wheels towards the kerb 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.
In the event of a failure of the
hydraulic braking system
While driving , to avoid any accidental
movement of the vehicle, use the parking
brake while depressing the brake pedal.
In this exceptional circumstance, it is
advisable to pull the parking brake up gently
so as not to block the rear wheels - risk of
skidding!
Release

► Pull the lever up gently and press the button
to release the parking brake.
When the vehicle is being driven, this
warning lamp coming on indicates that
the parking brake is still applied or has not been
fully released.
Manual gearbox
To change gear easily, always fully depress the
clutch pedal.
To prevent the mat from becoming caught under
the pedal:
– ensure that the mat is positioned correctly,
– never fit one mat on top of another.
Avoid leaving your hand on the gear knob as
the force exerted, even if slight, may wear the
internal components of the gearbox over time.
Engaging reverse gear

► Lift the ring under the knob to engage reverse
gear.
Never engage it until the vehicle has
come to a complete stop.
The movement must be done slowly to reduce
the noise when engaging reverse gear.
If fitted to the vehicle, the parking
sensors are activated when reverse gear
is engaged; an audible signal sounds.
For more information on the Parking
sensors, refer to the corresponding section.
Gear shift indicator
Depending on version or engine, this system
reduces fuel consumption by recommending a
higher gear change.
Gear shift recommendations should not be
considered compulsory. In fact, the road layout,
the traffic density and safety remain the deciding
factors when choosing the best gear. The driver
therefore remains responsible for deciding
whether or not to follow the indications issued by
the system.
The system cannot be deactivated.
Operation
The information appears in the instrument panel screen in the form of the SHIFT
indicator, accompanied by an upward arrow to
signal to the driver that they can change up.
The system adapts its gear shift recommendation according to the driving
conditions (slope, load, etc.) and the driver’s
requirements (power, acceleration, braking,
etc.).
The system never recommends engaging first
gear or reverse, or changing down.
Stop & Start
The Stop & Start function puts the engine temporarily into standby - STOP mode - during
phases when the vehicle is stopped (red lights,

71
Driving
6This system (also called HHC - Hill Hold
Control), integrated with the dynamic stability
control system, is activated in the following
conditions:
– the vehicle must be stationary, engine running,
foot on the brake,
– the gradient of the road must be steeper than
5%,
– uphill, the gearbox must be in neutral or in a
gear other than reverse,
– downhill, reverse gear must be engaged.
The hill start assist system is a driving
aid. It is not an automatic vehicle parking
function or an automatic parking brake.
Operation

With the brake pedal and clutch pedal pressed,
from the time you release the brake pedal,
without using the parking brake, you have
approximately 2 seconds to move off before the
vehicle starts to roll back.
During the moving off phase, the function is
deactivated automatically, gradually releasing
the braking pressure. During this phase, you
may hear the typical mechanical brake release
noise, signalling the imminent movement of the
vehicle.
Do not leave the vehicle while it is being
held temporarily by hill start assist.
If you need to get out of the vehicle with
the engine running, apply the parking brake
manually then ensure that the parking brake
indicator lamp is on.
Hill start assist is deactivated in the following
situations:
– when the clutch pedal is released,
– when the parking brake is applied,
– when the engine is switched off,
– if the engine stalls.
Malfunction
If a malfunction of the system occurs, this
warning lamp lights up, accompanied by
an audible signal and confirmed by a message
on the display. Have the system checked by a
CITROËN dealer or a qualified workshop.
Tyre under-inflation detection
System which automatically checks the
pressures of the tyres while driving.
The system continuously monitors the pressures
of the four tyres, as soon as the vehicle is
moving.
A pressure sensor is located in the valve of each
tyre (except the spare wheel).
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one or
more tyres.
The under-inflation detection system does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
regularly check the tyre pressures (including
the spare wheel) as well as before a long
journey.
Driving with under-inflated tyres, particularly
in adverse conditions (heavy load, high
speed, long journey):
– worsens road-holding,
– lengthens braking distances,
– causes premature wear of the tyres,
– increases fuel consumption.

72
Driving
The inflation pressures defined for the vehicle can be found on the tyre pressure
label.
Tyre pressures should be checked when the
tyres are "cold" (vehicle stopped for 1 hour or
after a journey of less than 6 miles (10 km) at
moderate speeds). Otherwise, add 0.3 bar to
the pressures shown on the label.
For more information on Identification
markings, including the tyre pressure label,
refer to the corresponding section.
The tyre pressure measurement unit can be configured with the MODE button: in
the "Tyre pressure measurement” menu, select
"psi/bar/kPa".
For more information on Vehicle configuration
(MODE), refer to the corresponding section.
Under-inflation alert
This is signalled by the fixed illumination of this warning lamp, accompanied by an
audible signal and, depending on equipment, the
display of a message.
In the event of an anomaly noted on just one of
the tyres, depending on equipment, the symbol
or the message displayed identifies it.
► Reduce speed immediately, avoid excessive
steering movements and avoid sudden braking.
► Stop the vehicle as soon as it is safe to do
so.
The loss of pressure detected does not always cause visible bulging of the tyre.
Do not rely on just a visual check.
► Using a compressor, such as the one in
the temporary puncture repair kit, check the
pressures of the four tyres when cold.
► If it is not possible to make this check
immediately, drive carefully at reduced speed.
► In the event of a puncture, use the
temporary puncture repair kit or the spare wheel
(depending on equipment).
The alert is kept active until the tyre/tyres concerned is/are reinflated, repaired or
replaced.
Malfunction
The flashing and then fixed illumination of this warning lamp, accompanied by the
illumination of the service warning lamp, and
depending on equipment, the display of a
message, indicates a fault with the system.
In this case, the tyre pressures are no longer
monitored.
This alert is also displayed if at least one wheel is not equipped with a sensor.
Contact a CITROËN dealer or a qualified
workshop to have the system checked or,
following a puncture, to have the original wheel,
equipped with a sensor, refitted.
Pneumatic suspension

If the vehicle is equipped with pneumatic
suspension, it is possible to change the height
of the rear sill, in order to facilitate loading or
unloading.




There is a normal sill level, as well as 3 higher
levels (from +1 to +3) and 3 lower levels (from
-1 to -3). Each level reached is displayed on the
instrument panel display screen.
Loading sill height manual
correction
Adjusting the platform sill up or down
► A quick press on one of the controls selects
the upper or lower level. Each press (diode lit)
increases or decreases by one level.
A long press on one of the controls selects the
maximum corresponding level (-3 or +3).
Returning to the normal sill height
► Press the same number of times in the
opposite direction of the displayed position.
Deactivation/Reactivation
► Press and hold both controls simultaneously
to deactivate/reactivate the system.
Deactivation is confirmed by the lighting of the
control LEDs.
Beyond a speed of 3 mph (5 km/h), the
system reactivates automatically.
Loading sill height
automatic correction
Beyond a speed of 12 mph (20 km/h), the
system automatically restores the rear sill height
to its normal level.
