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.

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.

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, the vehicle must remain within the
m aximum 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.
Drive the vehicle in a prudent
a nd 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.
In case of towing
Driving with a trailer places greater
d emands on the towing vehicle and
requires extra care from the driver.
Distribution of loads
F Distribute the load in the trailer so that the heaviest items are as close as possible to
the axle and the nose weight approaches
the maximum permitted without
exceeding it.
Air density decreases with altitude, thus
reducing engine performance. The maximum
towed load must be reduced by 10% for every
1,000
metres of altitude.
For more information on the Technical
data of your vehicle and particularly on
towable loads, refer to the corresponding
section.
Side wind
F Take into account the increased sensitivity to wind.
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.
Driving

Cooling
Towing a trailer on a slope increases the
t emperature of the coolant.
As the fan is electrically controlled, its cooling
capacity is not dependent on the engine speed.
F

T
o lower the engine speed, reduce your
speed.
The maximum towable load on an incline
depends on the gradient and the exterior
temperature.
In all cases, keep a
check on the coolant
temperature.
F

I
f this warning lamp and the
STOP warning lamp come on,
stop the vehicle and switch off
the engine as soon as possible.
New vehicle
Do not pull a
trailer before having driven at
least 620
miles (1,000 kilometres).
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes, the use of
engine braking is recommended.
Ty r e s
F Check the tyre pressures of the towing vehicle and of the trailer, observing the
recommended pressures.
Lighting
F Check the electrical lighting and signalling on the trailer and the headlamp beam height
of your vehicle.
For more information on Headlamp
beam height adjustment , refer to the
corresponding section.
The rear parking sensors will be
deactivated automatically to avoid the
audible signal if a
genuine CITROËN
towbar is used.
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.
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.
Note the number of the keys carefully; in
case of loss, inter vention by the CITROËN
dealer will be more efficient and quicker
if you present this number and the
confidential card.
When the ignition switch is turned on, a
dialogue is set up between the key and the
electronic immobiliser.
Do not make any modifications to the
electronic immobiliser system.
Operating the remote control, even when it
is in your pocket, may result in involuntary
unlocking of the doors.
The simultaneous use of other high
frequency equipment (mobile telephones,
domestic alarms, etc.), may inter fere
with the operation of the remote control
temporarily.
The remote control does not operate
while the key is in the ignition, even if the
ignition is off, except for reinitialisation.

Driving with the doors locked may make
access to the passenger compartment by
the emergency services more difficult 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:
-

e
nsure that you are given the
confidential card,
-

h
ave the keys recorded by a CITROËN
dealer to ensure that the keys in your
possession are the only ones which
can start the vehicle.
Confidential card
It contains the identification code necessary for
any work carried out by a CITROËN dealer on
the electronic immobiliser system. This code is
hidden by a
film, which should be removed only
if 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 it with you along
with your personal papers.
