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).
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 is active if the
vehicle speed is higher than 6 mph (10 km/h).
It is deactivated when the vehicle speed falls
below 3 mph (5 km/h).
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
When the vehicle is stationary
If this warning lamp comes on, accompanied by
the indication on the instrument panel screen, it
indicates a malfunction of the anti-lock braking
system which could result in a loss of control of
the vehicle when braking.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or a qualified workshop as
soon as possible.
When braking in an emergency, press
very firmly without releasing the
pressure. The warning lamp comes on for a few
seconds when the ignition is switched on
(ON position). If it does not switch off or
does not come on, contact a CITROËN
dealer or a qualified workshop.
Safety

143
When the vehicle is moving
If this warning lamp comes
on continuously it indicates a
malfunction of the anti-lock braking
system which could result in a loss of
control of the vehicle on braking.
The two warning lamps comes on at the
same time and the two warnings are
displayed alternately in the instrument
panel screen.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations.
The vehicle retains normal braking.
Drive carefully at moderate speed and contact
a CITROËN dealer or qualified workshop as
soon as possible.
If these two warning lamps come on, linked
with the warnings on the instrument panel
screen, they indicate a malfunction of the
electronic brake force distribution which could
result in a loss of control of the vehicle on
braking.
You must stop as soon as it is safe to do so.
Contact a CITROËN dealer or a qualified
workshop.

Associated systems which guarantee 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 flashing of this
symbol on the instrument panel
screen.
Trajectory control systems
F Press this button, located to the right of the steering wheel, until the symbol appears in
the instrument panel screen.
Operation
They operate when the vehicle speed is higher
than 10 mph (15 km/h).
They come into operation in the event of a grip
or trajectory problem.
Safety

145
ReactivationOperating fault
The illumination of one of these warning lamps
accompanied by a message in the instrument
panel screen indicates a malfunction of these
systems.
Contact a CITROËN dealer or a qualified
workshop to have the ASC/ TCL systems
checked. The ASC/ TCL 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 functioning of these
systems depends on observation of the
manufacturer's recommendations on:
-

w
heels (tyres and rims),
-

b
raking components,
-
el

ectronic components,
-

a
ssembly and repair procedures.
After an impact, have these systems
checked by a CITROËN dealer or a
qualified workshop.
F

P

ress this button again to reactivate
the

ASC and TCL systems.
When the warning lamp goes off, this indicates
the reactivation of the ASC and TCL systems.

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.
