Anti-lock braking system and
electronic brake force distribution
Linked systems which improve the stability
and manoeuvrability of your vehicle when
braking, in particular on poor or slippery
surfaces.
Operation
The anti-lock braking system comes into
operation automatically when there is a risk
of wheel lock.
Normal operation of the ABS may make
itself felt by slight vibration of the brake
pedal accompanied by some noise.
When braking in an emergency
, press
very firmly without releasing the
pressure.
Switching off
These systems cannot be deactivated by
the
driver.
BrAKInG ASSIStA nc E SYS t EMS
Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
-

anti-lock braking system (ABS),
-


electronic brake force distribution

(EBFD),
-

emergency braking assistance (EBA).

Good practice
The ABS system does not provide shorter
braking distances. On very slippery surfaces
(black ice, oil...) the ABS can extend braking
distances. For emergency braking, press the
brake pedal hard and do not release it, even
on a slipper surface; you will then be able to
steer the vehicle and avoid an obstacle.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.Emergency braking assistance
System which, in an emergency, enables
you to obtain the optimum braking pressure
more quickly, thus reducing the stopping
distance.
Operation
It is triggered by 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.
Switching off
This system cannot be deactivated by
the driver.
Operating fault
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 which could result in
loss of control of the vehicle when braking.
For maximum braking efficiency, a
bedding-in period of around 300 miles
(500 kilometres) is needed. During this
period it is recommended that you avoid
harsh, repeated or prolonged braking. If this warning lamp comes on,
together with the ABS warning
lamp, accompanied by a message
in the instrument panel screen,
it indicates a fault with the electronic brake
force distribution which could result in loss
of control of the vehicle when braking. When braking in an emergency, press
firmly without releasing the pressure.
You must stop as soon as it is safe to do so.
In either case, contact a CITROËN dealer or
a qualified workshop.

the
driver.
dynamic stability control
( d S c )
The electronic stability programme acts on
the brake of one or more wheels and on the
engine to keep the vehicle on the trajectory
required by the driver, within the limits of the
laws of physics.
With the DSC system, maintain course
without trying to countersteer.
Operation
The DSC system is activated automatically
each time the vehicle is started. Operating fault
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 a
qualified workshop. Operation
This system is activated automatically every
time the vehicle is started.
In the event of a problem of adhesion or
trajectory, this system comes into play.
Switching off
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow,
on soft ground...), it may be advisable to
deactivate the ASR system, so that the
wheels can spin freely and regain grip.
-

Press this button, located in the

middle of the dashboard, to deactivate
the
system.
Anti-slip regulation (ASr)
Anti-slip regulation (also known as traction
control) optimises traction, avoiding wheel
spin by acting on the brakes of the driving
wheels and the engine.
If the button's warning lamp comes
on, accompanied by a message in the
instrument panel screen, this indicates that
the ASR system is deactivated.
It comes into operation in the
event of a grip or trajectory
problem.
This is indicated by flashing of this warning
lamp in the instrument panel.

reactivation
The ASR system is reactivated automatically
every time the ignition is switched back on.
-

Press this button again to reactivate it

manually.
Operating fault 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 a
qualified workshop. Good practice
The DSC and ASR systems offer exceptional
safety in normal driving, but this should not
encourage the driver to take extra risks or
drive at high speed.
The correct operation of these systems
depend on observation of the manufacturer's
recommendations regarding the wheels
(tyres and rims), the braking components,
the electronic components and assembly
and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a qualified
workshop.Load inertia control
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.
All such variations have an effect on braking,
traction, the behaviour of the vehicle when
cornering and the tendency to overturn.
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 than remains more
securely on its intended trajectory.

Intelligent traction c ontrol
System to improve traction on slippery
surfaces (snow, black ice, mud...)
This system checks for situations of difficult
surface adhesion that could make it difficult
to move off or make progress.
In these situations, Intelligent
t
raction

c

ontrol takes over from the AS r 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.
Press this button, located in the middle of
the dashboard, to activate the system; the
indicator lamp in the button comes on.

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, accompanied by an
increasing audible signal, if the driver has
not fastened their seat belt.
The driver's seat is fitted with a pyrotechnic
pretensioner and a force limiter.
On versions with a passenger's front 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.
Height adjustment
For the driver or outer passenger seat,
squeeze the control at the adjustable top
mounting, slide the assembly, then release
at the desired position to lock it.
The height of the seat belt for the centre

The rear 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.
A carrier is provided at each outer seat to
allow the seat belt buckle to be secured
when not in use.
Good practice
The driver must ensure that passengers use
the seat belts correctly and that they are all
strapped in securely before moving off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
The seat belts are fitted with an inertia reel
which automatically adjusts the length of the
strap to your size.
Do not use accessories (clothes pegs, clips,
safety pins, etc.) which allow the seat belt
straps to fit loosely.
You can unfasten the seat belt by pressing
the red button on the buckle. Guide the seat
belt after unfastening.
Ensure that the seat belt has reeled in
correctly after use.
After folding or moving a seat or a rear
bench seat, ensure that the seat belt has
reeled in correctly and that the buckle is
ready to accommodate the tongue.
The airbag warning lamp also
comes on if the pretensioners are
deployed. Contact a CITROËN
dealer or a qualified workshop.
In the event of an impact
Only for the front seats, and depending on
the nature and seriousness of the impact,
the pretensioning device may be deployed
before and independently of inflation of the
airbags. It instantly tightens the seat belts
against the body of the occupants.
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.
The force limiter reduces the pressure of the
seat belt against the body of the occupants.
The pyrotechnic pretensioners are active
when the ignition is switched on and the
seat belt fastened.
The inertia reels are fitted with a device
which automatically locks the strap in the
event of a collision or emergency braking or
if the vehicle rolls over.

In order to be effective, a seat belt:
-
must restrain one person only
,
-

must not be twisted, check by pulling in

front of you with an even movement,
-

must be tightened as close to the body

as possible.
The upper part of the seat belt should be
positioned in the hollow of the shoulder.
The lap part should be placed as low as
possible on the pelvis.
Do not invert the seat belt buckles as they
will not fulfil their role completely. If the
seats are fitted with armrests, the lap part of
the seat belt should always pass under the
armrest.
Check that the seat belt is fastened correctly
by pulling the strap firmly.r ecommendations for children
Use an appropriate child seat if the
passenger is under 10 years or less than
one and a half metres tall.
Never carry a child on your knees, even with
the seat belt fastened.
For more information on child seats,
refer to the "Safety - Children on board"
section. In accordance with current safety
regulations, your CITROËN dealer can
guarantee all work or any checks, from
testing to maintenance, on your seat belt
equipment.
Have the seat belts checked regularly (even
after a minor impact) by a CITROËN dealer
or a qualified workshop: they must not show
any signs of wear, cutting or fraying and they
must not be converted or modified.
Clean the seat belt straps with soapy
water or a textile cleaning product, sold
by CITROËN dealers.
