Definitions
Anti-lock braking system (ABS)
and electronic brake force
distribution (EBFD)
This system improves the stability and
manoeuvrability of your vehicle when braking
and contributes towards improved control on
corners, in particular on poor or slippery road
surfaces.
The ABS prevents wheel lock in the event of
emergency braking.
The electronic brake force distribution system
(EBFD) manages the braking pressure wheel
by wheel.
Emergency braking assistance
(EBA)
In an emergency, this system permits the
optimum braking pressure to be reached
more quickly, therefore reducing the stopping
distance.
It is triggered in relation to the speed at which
the brake pedal is pressed. The effect of this is
a reduction in the resistance of the pedal and
an increase in braking efficiency.
Anti-slip regulation (ASR)
The ASR system (also known as Traction
Control) optimises traction in order to limit
wheel slip by acting on the brakes of the driving
wheels and on the engine. It also improves
the directional stability of the vehicle on
acceleration.
Safety

69
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.

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.

Driving recommendations
Observe the driving regulations and remain
vigilant whatever the traffic conditions.
Pay close attention to the traffic and keep your
hands on the wheel so that you are ready to
react at any time to any eventuality.
As a safety measure, the driver should only
carry out any operations that require close
attention when the vehicle is stationary.
On a
long journey, a break every two hours is
strongly recommended.
In difficult weather, drive smoothly, anticipate
the need to brake and increase the distance
from other vehicles.
Never leave the engine running in
an enclosed area without adequate
ventilation: internal combustion engines
emit toxic exhaust gases, such as carbon
monoxide. There is a
risk of poisoning and
death!
In very severe wintry conditions
(temperatures below -23°C), to guarantee
correct operation and the longevity of
the mechanical elements of your vehicle,
engine and gearbox, the engine must be
left running for 4
minutes before driving.
Driving 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.
Important!
If you are obliged to drive through water:
- c heck that the depth of water does not
exceed 15
cm, taking account of waves that
might be generated by other users,
-

d
eactivate the Stop & Start system,
-

d
rive as slowly as possible without stalling.
Under no circumstances exceed 6
mph
(10


km/h),
-

d
o not stop and do not switch off the engine.
On leaving the flooded road, as soon as
circumstances 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.
Never drive with the parking brake
applied – risk of overheating and damage
to the braking system!
Do not park and do not run the engine
with the vehicle stationary, in areas where
substances and combustible materials
(dry grass, leaves, etc.) can come into
contact with the hot exhaust system – risk
of fire!
Never leave a vehicle unsuper vised with
the engine running. If you have to leave
your vehicle with the engine running, apply
the parking brake and put the gearbox into
neutral or position N or P , depending on
the type of gearbox.
To assure the durability of your vehicle and
your safety, remember that certain precautions,
described hereafter, should be taken when
driving your vehicle:

Driving

88
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.
