Braking assistance systems
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 sur faces.
Activation
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.
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.
If this warning lamp comes on,
together with the STOP and ABS
warning lamps, accompanied by an
audible signal and 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.
Emergency braking assistance
System which, in an emergency, enables you
to obtain the optimum braking pressure more
quickly, thus reducing the stopping distance.
Activation
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.
Group of supplementary systems which help
you to obtain optimum braking in complete
safety in emergency situations:
-

a

nti-lock braking system (ABS),
-

e

lectronic brake force distribution (EBFD),
-

e

mergency braking assistance (EBA).
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.When braking in an emergency, press
firmly without releasing the pressure.
When braking in an emergency,
press very firmly without releasing
the

pressure. You MUST stop as soon as it is safe to do so.
In both cases, contact a CITROËN dealer or a
qualified workshop.

Trajectory control systems
Anti-slip regulation (ASR) and dynamic stability
control (DSC)
Activation
This is indicated by flashing of this
warning lamp in the instrument panel.
Your vehicle has a system to improve traction
on snow: intelligent traction control
.
This system detects situations of low adhesion
that might make moving off and progress
difficult on deep fresh snow or compacted
snow.
In these situations the intelligent traction
control system regulates the amount of wheel
slip to optimise the traction and trajectory
control of your vehicle.
For vehicles with Hydractive III + suspension,
manual adjustment of ground clearance to
the intermediate position improves further the
ability to make progress in deep snow (see the
relevant paragraph).
The anti-slip regulation (also known as traction
control) optimises traction to prevent skidding
of the wheels, by acting on the brakes of the
driving wheels and on the engine.
The electronic stability control 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.
Intelligent traction control
system ("Snow motion")
These systems are activated automatically
each time the vehicle is started.
They come into operation in the event of a grip
or trajectory problem.
The use of snow tyres is strongly
recommended on sur faces with low
adhesion.

The indicator lamp in the button
comes on.
Contact a CITROËN dealer or a qualified
workshop to have the system checked.
The DSC and ASR systems no longer act
on the operation of the engine and on the
brakes in the event of a involuntary change of
trajectory.
F

P

The indicator lamp in the button
goes
off.
The systems are reactivated automatically
each
time the ignition is switched back on or
from 30
mph (50 km/h).
Below 30 mph (50 km/h), you can reactivate
them manually:
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate
the DSC and ASR, so that the wheels can turn
freely and regain grip.

The DSC and ASR 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, black ice) that the risk of loss of grip
increases. It is therefore important for your safety to keep the DSC and ASR systems
activated in all conditions, and particularly in difficult conditions.
The correct operation of these systems depends on observation 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 the DSC and ASR systems in wintry conditions,
the vehicle must be fitted with four snow tyres, allowing the vehicle to retain neutral
handling on the road.After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.

This system improves safety in the front seats
in the event of a front impact.
Depending on the seriousness of the impact,
the pretensioning system instantly tightens the
seat belt against the body of the occupant. The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of the
seat belt against the chest of the occupant,
so increasing his protection.

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 bear any trace of cuts or fraying,
-

n
ot be converted or modified to avoid
affecting its performance.
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 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.
In the event of an impact
Depending on the nature and seriousness
of the impact , the pretensioning 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.
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 fulfill 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 are fitted with an automatic
locking device which comes into operation in
the event of a collision, emergency braking
or if the vehicle rolls over. You can release
the device by pulling the strap firmly and
then releasing it so that it reels in slightly.

Airbags
System designed to contribute towards
improving the safety of the occupants (with
the exception of the rear centre passenger)
in the event of a violent collision. The airbags
supplement the action of the force-limiting
seat belts.
If a collision occurs, the electronic detectors
record and analyse the front and side impacts
sustained in the impact detection zones:
-

i
n the case of a serious impact, the airbags
are deployed instantly and contribute
towards best protecting the occupants of
the vehicle (with the exception of the rear
centre passenger); immediately after the
impact, the airbags deflate rapidly so that
they do not hinder visibility or the exit of the
occupants,
-

i
n the case of a minor or rear impact or in
certain roll-over conditions, the airbags
may not be deployed; the seat belt alone
contributes towards your protection in
these situations.
Impact detection zones
A. Front impact zone.
B. S ide impact zone.
The airbags do not operate when
the ignition is switched off.
This equipment will only deploy once.
If a second impact occurs (during
the same or a subsequent accident),
the deployment of airbag will not be
triggered again. Deployment of one or more airbags
is accompanied by a slight emission
of smoke and a noise, due to the
activation of the pyrotechnic cartridge
incorporated in the system.
This smoke is not harmful, but sensitive
individuals may experience slight
irritation.
The noise of the detonation related to
the deployment of one or more airbags
may result in a slight loss of hearing for
a short time.
