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.

104
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.

106
Airbags
Deactivating the passenger's front airbag
When OFF is selected, the passenger's front
airbag will not be triggered in the event of an
impact.
As soon as the child seat is removed, select ON to
re-activate the airbag and thus ensure the safety
of your passenger in the event of an impact. Lateral airbags and curtain airbags
If your vehicle is fitted with lateral airbags,
these are fitted to the front seat backs on
the door side.
The curtain airbags are fitted to the door
pillars and the upper part of the passenger
compartment, in the roof over the front cab
seats.
They inflate between the occupant and the
glazed area.
They are deployed independently of each
other depending on which side the collision
occurs.
To ensure the safety of your child, it is
essential to deactivate the passenger's
front airbag when you install a rearward
facing child seat on the front passenger
seat. Otherwise, the child would risk being
killed or seriously injured if the airbag were
to inflate.
If your vehicle is not fitted with this facility:
do not install a rearward facing child seat. Deactivation check
This is confirmed by the
illumination of this warning lamp,
accompanied by a message in
the display screen, every time the
engine is started.
Operating fault If this warning lamp comes on,
contact a CITROËN dealer to
have the vehicle checked.
Refer to the "Technology on board -
Vehicle configuration" section.
The setting is made using the "
MODE "
button: in the "Passenger airbag" menu,
select " OFF ".

Transport solutions
ACCESSORIES
Distribution of loads: distribute the load in
the trailer so that the heaviest objects are as
close as possible to the axle and the nose
weight is close to the maximum authorised
without, however, exceeding it.
Driving advice
A towed vehicle must free wheel: gearbox in
neutral.
Cooling: towing a trailer on a slope
increases the coolant temperature.
As the fan is electrically controlled, its
cooling capacity is not dependent on the
engine speed.
On the contrary, use a high gear to lower the
engine speed and reduce your speed.
In all cases, pay attention to the coolant
temperature. Tyres: check the tyre pressures of the
towing vehicle and of the trailer, observing
the recommended pressures.
Fitting a towbar
We recommend the use of genuine
CITROËN towbars and their harnesses,
which have been tested and approved from
the design stage of your vehicle and that
the fitting of this equipment is entrusted to a
CITROËN dealer.
These genuine towbars are compatible with
the operation of the rear parking sensors
and the reversing camera, if fitted to your
vehicle.
If this equipment is not fitted by a CITROËN
dealer, it must be fitted in line with the
manufacturer's instructions.
Good practice
In certain cases of particularly arduous
use (towing the maximum load up a steep
slope in high temperatures), the engine
automatically limits its power. In this
case, the automatic cutting off of the air
conditioning allows the engine power to be
recovered.
If the coolant temperature
warning lamp comes on, stop the
vehicle and switch off the engine
as soon as possible.
Refer to the "Checks - Levels and
checks" section.
Brakes: towing increases the braking
distance. Drive at a moderate speed,
change down early and brake gradually. Side wind: sensitivity to side wind is
increased. Drive smoothly and at a
moderate speed.
ABS: the system only controls the vehicle,
not the trailer.
Rear parking sensors: the system does not
operate while the vehicle is towing.
Refer to the "Technical data -
Identification markings" section.

Levels and checks
Used products
Avoid prolonged contact of used oil or fluids
with the skin.
Most of these fluids are harmful to health or
indeed very corrosive.
Do not discard used oil or fluids into sewers
or onto the ground.
Take used oil to a CITROËN dealer or
a qualified workshop (France) or to an
authorised waste disposal site.
LEVELS
These regular maintenance operations
will keep your vehicle in good running
order. Ask for advice at a CITROËN dealer
or consult the maintenance and warranty
guide contained in the handbook pack.
To maintain the reliability of engines and
emission control systems, the use of
additives in engine oil is prohibited.

CHECKS
Levels and checks
Cooling system
Only use the fluid recommended by the
manufacturer. Otherwise, you risk seriously
damaging your engine. When the engine
is warm, the temperature of the coolant is
controlled by the engine fan. As this fan can
operate with the ignition key removed and
because the cooling system is pressurised,
wait for at least one hour after the engine
has stopped before carrying out any work.
Slacken the cap by 1/4 of a turn to release
the pressure to prevent any risk of scalding.
When the pressure has dropped, remove the
cap and top up the level with coolant.
Power steering fluid level
The vehicle must be parked on level ground
with the engine cold. Unscrew the cap
integrated with the gauge and check the
level which must be between the MIN and
MAX marks.
For access to the reservoir filler cap, remove
the protective cover by removing its three
fixing screws, then remove the second cover
fitted to the cap. Topping up
The level must be between the MIN and
MAX marks on the expansion bottle. If
more than 1 litre of fluid is required to top
up the level, have the system checked by a
CITROËN dealer or a qualified workshop.
Windscreen wash and headlamp wash level
Capacity of the reservoir: approximately
5.5 litres.
For access to the reservoir filler cap, pull on
the telescopic filler pipe and unscrew the
cap a quarter of a turn.
For best quality cleaning and to prevent
freezing, this fluid must not be topped up or
replaced with plain water.
In wintry conditions, the use of an alcohol or
methanol based fluid is recommended.
For access to the header tank filler cap,
remove the protective cover by removing its
three fixing screws.
If fluid has to be added frequently, this
indicates a failure which must be checked by
a CITROËN dealer or a qualified workshop
as soon as possible.

126
Levels and checks

The presence of this label, in particular
with the Stop & Start system, indicates the
use of a specific 12 V lead-acid battery
with special technology and specification.
The involvement of a CITROËN dealer
or a qualified workshop is essential when
replacing or disconnecting the battery. These operations will keep your vehicle
in good running order. Ask for advice
from a CITROËN dealer or refer to the
maintenance and warranty guide included in
the handbook pack.
CHECKS
Battery
At the start of winter, have your battery
checked by a CITROËN dealer or a qualified
workshop.
Bleeding water from the Diesel filter
If this warning lamp comes on,
bleed the filter, or bleed regularly
each time the engine oil is
changed.
To drain the water out, unscrew the bleed
screw or the water in Diesel sensor, located
at the base of the filter. Leave open until
all of the water has been drained out. Then
tighten the bleed screw or the water sensor.
Air filter and passenger compartment filter
A clogged passenger compartment filter
may reduce the performance of the
air conditioning system and generate
undesirable odours. The replacement
intervals for these components are given in
the maintenance and warranty guide.
Depending on the environment (dusty
atmosphere...) and the use of the vehicle
(urban driving...), change them twice as
often if necessary.
Refer to the "Checks - Under the
bonnet" section.
HDi engines use advanced technology.
All work requires a special qualification
which is guaranteed by a CITROËN dealer
or a qualified workshop.
