Operating fault
If this warning lamp comes on,
accompanied by an audible signal
and a message in the screen, it
indicates a malfunction of 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
screen, it indicates a malfunction of
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.
In either case, contact a CITR
oËn

dealer or a
qualified workshop. When braking in an emergency, press
firmly without releasing the pressure.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.
You must stop as soon as it is safe to do so.

the dashboard.
If this warning lamp comes on in the
instrument panel and the indicator
lamp on the button comes on, this
indicates that the
d
S
C and a
S
R
systems are deactivated.
Reactivation
These systems are reactivated automatically
each time the ignition is switched back on or

P
ress the button again to reactivate them
manually.
Operating fault
If this warning lamp comes on,
accompanied by an audible signal
and a message in the multifunction
screen, this indicates a malfunction
of these systems.
Trajectory control systems
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.
Anti-slip regulation (ASR)
and dynamic stability
control (DSC)
This is indicated by flashing of this
warning lamp in the instrument panel.
Activation
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
d
S
C/
aS
R 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 depends on observation of
the manufacturer's recommendations
regarding wheels (tyres and rims),
braking components, electronic
components and assembly and repair
procedures.

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.

Never allow a child to travel on your lap.
For more information, refer to the "Child
seats" section.
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.
d
ep
loyment 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 CITR
oËn

dealer or a qualified
workshop.
The driver must ensure that passengers use
the seat belts correctly and that they are all
restrained securely before setting off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
do n

ot 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.
be

fore 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.

airbags
Front airbags
System which protects the driver and front
passenger in the event of a serious front impact
in order to limit the risk of injury to the head and
chest.
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.
Deployment
The airbags are deployed, except for the
passenger's front airbag if it is deactivated,
in the event of a serious front impact applied
to all or part of the front impact zone A, in
the longitudinal centreline of the vehicle on a
horizontal plane and directed from the front to
the rear of the vehicle.
The front airbag inflates between the front
occupant of the vehicle and the dashboard to
cushion their for ward movement.
Impact detection zones
A. Front impact zone.
B. S ide impact zone.
System designed to contribute towards
improving the safety of the occupants (with
the exception of the rear centre passenger)
in the event of violent collisions. The airbags
supplement the action of the force-limiting
seat belts (with the exception of the centre rear
passenger).
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 better protection of 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 ensuring your
protection in these situations.
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
airbag will not be deployed again.
de

ployment of one or more of the
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 detonation related to the
deployment of one or more airbags may
result in a slight loss of hearing for a
short time.
