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 is active if the

Associated systems which contribute to the directional stability of the vehicle within the limits of the laws of physics:
- t raction control (TCl) ,
-

a
ctive stability control (ASC).
Traction control and active stability control
Traction control optimises traction to prevent
wheel spin, by acting on the brakes of the
driving wheels and on the engine.
Active 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.Activation
These systems are activated automatically
each time the vehicle is started.
The illumination of this warning lamp
in the instrument panel indicates
that the ASC and TCL systems are
deactivated.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground, ...), it may be advisable to deactivate
the ASC system, so that the wheels can move
freely and regain grip.
This is indicated by the flashing of
this symbol on the instrument panel
screen.
Trajectory control systems
F Press this button, located to the left of the steering wheel, until the symbol appears in
the instrument panel screen.

Seat belts
Front seat belts
The front seat belts are fitted with a
pretensioning and force limiting system.
This system improves safety in the front
seats in the event of a front or side impact.
Depending on the severity of the impact, the
pretensioning system instantly tightens the seat
belts against the body of the occupants.
The pretensioning seat belts are active when
the ignition is on.
The force limiter reduces the pressure of the
seat belt on the chest of the occupant,
so improving their protection.

Advice
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.
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 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.
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.
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.
