Dynamic stability control (DSC)
If there is a difference between the path
f ollowed by the vehicle and that required by
the driver, the DSC monitors each wheel and
automatically acts on the brake of one or more
wheels and on the engine to return the vehicle
to the required path, within the limits of the laws
of physics.
Anti-lock braking system
(ABS) and electronic brake
force distribution (EBFD)
If this warning lamp comes on,
accompanied by an audible signal
and a
message in the instrument
panel screen, it indicates a
fault with
the anti-lock braking system (ABS)
which could result in loss of control
of the vehicle when braking.
If these warning lamps come on,
accompanied by a
message in the
instrument panel screen, it indicates
a
fault with the electronic brake force
distribution (EBFD) system which
could result in loss of control of the
vehicle when braking.
You must stop as soon as it is safe to do so.
In both cases, contact a
CITROËN dealer or
a


qualified workshop. For maximum braking efficiency, a
bedding-in period of around 310
miles
(500 kilometres) is needed. During this
period, it is advisable to avoid any sudden,
repeated and prolonged braking.
The ABS does not provide shorter braking
distances. On very slippery sur faces (ice,
oil, etc.) the ABS may extend braking
distances.
When changing wheels (tyres and rims),
make sure that these are approved for
your vehicle.
For emergency braking, press the
brake pedal ver y hard and do not
release it, even on a
slipper y sur face;
you will then be able to continue
steering the vehicle to avoid an
obstacle.
After an impact, have these systems
checked by a
CITROËN dealer or
a


qualified workshop.
Dynamic stability control
(DSC)
Switching on
The DSC system is activated automatically
each time the vehicle is started.
It comes into operation in the event of a grip or
trajectory problem.
This is indicated by this warning
lamp flashing in the instrument
panel.
Deactivation
This system cannot be deactivated by the
driver.
Malfunction
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 by
a


qualified workshop.

Anti-slip regulation (ASR)
Switching on
This system is activated automatically every
time the vehicle is started.
In the event of a grip or trajectory problem, this
system comes into play.
Deactivation
In exceptional conditions (starting a vehicle
w hich is bogged down, stuck in snow, on soft
ground, etc.), it may be advisable to deactivate
the ASR system, so that the wheels can turn
freely and regain grip.
F

P
ress this button to deactivate the system.
The button's warning lamp comes on
accompanied by a
message in the instrument
panel screen, indicating that the ASR system is
deactivated.
Reactivation
The ASR system is reactivated automatically
every time the ignition is switched back on.
F

P
ress this button again to reactivate it
manually.
Malfunction
If this warning lamp comes on,
accompanied by an audible signal
and a
message in the instrument
panel screen, this indicates a
fault
with the ASR system.
Have it checked by a
CITROËN dealer or by
a


qualified workshop. ASR/DSC
These systems offer increased safety
in normal driving, but they should not
encourage the driver to take extra risks or
drive at high speed.
It is in conditions of reduced grip (rain,
snow, ice) that the risk of loss of grip
increases. It is therefore important for your
safety to keep these systems activated in
all conditions, and particularly in difficult
conditions.
The correct operation of these
systems depends on obser vation of
the manufacturer's recommendations
regarding as much the wheels (tyres and
rims), braking and electronic components
as the assembly and repair procedures
used by CITROËN dealers.
To benefit in full from the effectiveness
of these systems in wintry conditions,
the vehicle must be fitted with four snow
tyres, allowing the vehicle to retain neutral
behaviour on the road.
Safety

71
Intelligent Traction Control
System to improve traction on slippery sur faces
(snow, ice, mud, etc.)
This system checks for situations of difficult
sur face grip that could make it difficult to move
off or make progress.
In these situations, Intelligent Traction
Control takes over from the ASR system, by
transferring drive to the wheel with the best grip
on the ground to provide the best traction and
trajectory control.
Switching on
On starting the vehicle, this system is
deactivated.
F

P
ress this button to switch the system on;
the warning lamp in the button comes on.
This system is active up to about 19
mph
(30


km/h).
Once the speed exceeds 19
mph (30 km/h),
the system is deactivated automatically, but the
warning lamp in the button stays on. The system is reactivated automatically
as soon as the speed drops below 19
mph
(30

km/h).
Deactivation
F Press this button to deactivate the system;
the warning lamp in the button goes off and
the ASR system is active again.
Malfunction
If a fault occurs with the intelligent
t raction control, this warning lamp
comes on.
Have it checked by a
CITROËN dealer or by
a


qualified workshop.
Load inertia control
All such variations have an effect on braking,
traction, the behaviour of the vehicle when
cornering and the tendency to overturn.
The true total weight of a

commercial vehicle
can vary considerably depending on the load
carried. As a

result, the centre of gravity of the
vehicle can move, both longitudinally and in
height. Load inertia control estimates the true total
weight of the vehicle by analysing its behaviour
under acceleration and braking.
This system then adapts the operation of the
DSC and ASR systems according to the weight
distribution in the vehicle. In critical situations,
your vehicle therefore remains more securely
on its intended trajectory.
Hill Descent Control
System that provides assistance when
descending on sur faces with poor grip (mud,
gravel, etc.) or on a
steep gradient.
This system reduces the risk of slip or loss of
control of the vehicle while descending a
hill.
It keeps the vehicle at a
steady speed during
a


descent by acting independently and with
varying force on each of the brakes.

The driver must ensure that passengers use
the seat belts correctly and that they are all
fastened before setting off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
Do not interchange the seat belt buckles as
they will not fulfil their role fully.
The seat belts are fitted with an inertia reel
permitting automatic adjustment of the length
of the strap to your size. The seat belt is
stowed automatically when not in use.
Before and after use, ensure that the seat belt
is reeled in correctly.
The lower part of the strap must be positioned
as low as possible on the pelvis.
The upper part must be positioned in the
hollow of the shoulder.
The inertia reels have an automatic locking
device at the time of a collision, during
sudden braking or if the vehicle turns over.
You can release the device by pulling the
strap firmly and then releasing it so that it
reels in slightly.
Advice
In order to be effective, a seat belt must:
- b e tightened as close to the body as
possible,
-

b
e pulled in front of you with a smooth
movement, checking that it does not
twist,
-

b
e used to restrain only one person,
-

n
ot show any signs of cuts or fraying,
-

n
ot be converted or modified to avoid
affecting its performance.
In accordance with current safety
regulations, for all repairs on your vehicle's
seat belts, go to a
qualified workshop with
the skills and equipment needed, which
a
CITROËN dealer is able to provide.
Have your seat belts checked regularly by
a
CITROËN dealer or a qualified workshop,
particularly if the straps show signs of
damage.
Clean the seat belt straps with soapy
water or a
textile cleaning product, sold by
CITROËN dealers.
After folding or moving a
seat or rear bench
seat, ensure that the seat belt is positioned
and reeled in correctly. Recommendations for children
Use a
suitable child seat if the passenger is
less than 12
years old or shorter than one and
a
half metres.
Never use the same seat belt to secure more
than one person.
Never allow a
child to travel on your lap.
For more information on Child seats , refer to
the corresponding section.
In the event of an impact
Depending on the nature and seriousness
of the impact , the pyrotechnic device may
be deployed before and independently of the
airbags. 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 belts
system checked and, if necessary, replaced,
by a
CITROËN dealer or a qualified
workshop.
Safety

75
AirbagsThe 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.
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:
-

i

n the event of a

serious collision, the
airbags are deployed instantly and
contribute towards better protection of
occupants of the vehicle; immediately after
the impact, the airbags deflate rapidly so as
not to hinder visibility or a

potential exit by
the occupants,
-

i

n 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. 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 which protects the driver and
passenger(s) in the event of a serious front
impact in order to limit the risk of injury to the
head and thorax.
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.
Malfunction
If this warning lamp comes on,
contact a CITROËN dealer to have
the system checked.
Lateral airbags and curtain
airbags
If your vehicle is fitted with lateral airbags,
these are fitted to the front seat backrests on
the door side.
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.
Malfunction
If this warning lamp comes on,
contact a CITROËN dealer to have
the system checked.

76
Advice
For the airbags to be fully effective,
observe the safety recommendations
below.
Adopt a normal and upright sitting position.
Fasten your seat belt, ensuring it is positioned
c o r r e c t l y.
Do not leave anything between the occupants
and the airbags (a child, pet, object, etc.), nor
fix or attach anything close to the inflation
trajectory of the airbags; 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 or broken into, have the airbag systems
checked.
All work on the airbag system must be carried
out by a
CITROËN dealer or a qualified
workshop.
Even if all of the precautions mentioned
are obser ved, a risk of injury or of minor
burns to the head, chest or arms when an
airbag is deployed cannot be ruled out. The
bag inflates almost instantly (within a


few
milliseconds) then deflates within the same
time discharging the hot gas via openings
provided for this purpose. Front airbags
Do not drive holding the steering wheel by its
spokes or resting your hands on the centre
part of the wheel.
Passengers must not place their feet on the
dashboard.
Do not smoke as deployment of the airbags
can cause burns or the risk of injury from
a
cigarette or pipe.
Never remove or pierce the steering wheel or
hit it violently.
Do not fit or attach anything to the steering
wheel or dashboard, this could cause injuries
with deployment of the airbags.
Lateral airbags
Use only approved covers on the seats,
compatible with the deployment the lateral
airbags. For information on the range of seat
covers suitable for your vehicle, you can
contact a
CITROËN dealer.
Do not attach anything to or hang anything
from the seat backrests (clothes, etc.) as
this could cause injuries to the thorax or arm
when the lateral airbag is deployed.
Do not sit with the upper part of the body any
nearer to the door than necessary. Curtain airbags
Do not attach anything to or hang anything
from the roof, as this could cause head
injuries when the curtain airbag is deployed.
If fitted on your vehicle, do not remove the
grab handles installed on the roof, they play
a


part in securing the curtain airbags.

General points relating to
child seats
The regulations on carrying children are
specific to each country. Refer to the
legislation in force in your country.
For maximum safety, please obser ve the
following recommendations:
-

i

n accordance with European regulations,
all children under the age of 12
or less
than one and a
half metres tall must
travel in approved child seats suited to
their weight , on seats fitted with a
seat belt
or ISOFIX mountings,
-

s
tatistically, the safest seats in your
vehicle for carr ying children are the rear
seats,
-

a c
hild weighing less than 9 kg must
travel in the rear ward facing position
both in the front and in the rear. It is recommended
that children travel in
the rear seats of your vehicle:
-
re
arward facing
up to the age of 3,
- fo rward facing
over the age of 3.
Child seat at the rear
"Rearward facing"
When a "rear ward facing" child seat
is installed on a
rear passenger
seat , move the vehicle's front seat
for ward and straighten the backrest
so that the "rear ward facing" child
seat does not touch the vehicle's
front seat.
" Forward facing "
When a "for ward facing" child seat
is installed on a
rear passenger
seat , move the vehicle's front seat
for wards and straighten the backrest
so that the legs of the child in the
"for ward facing" child seat do not
touch the vehicle's front seat. Ensure that the seat belt is correctly
tensioned.
For child seats with a
support leg, ensure
that the latter is in firm contact with the
floor. If necessary, adjust the front seat of
the vehicle.
