BRAKING ASSISTANCE SYSTEMS
Group of supplementary systems which
help you to obtain optimum braking in
complete safety in emergency situations:
- the anti-lock braking system (ABS),
- the electronic brake force distribu-tion (EBFD),
- the emergency braking assistance (EBA).
Anti-lock braking system and electronic brake force distribution
Linked systems which improve the sta-
bility and manoeuvrability of your vehi-
cle when braking, in particular on poor
or slippery surfaces.
When braking in an emergency,
p r e s s v e r y fi r m l y w i t h o u t r e l e a s i n g
the pressure. When replacing wheels (tyres and
rims), ensure that they conform to
the manufacturer’s recommenda-
tions.
Operating fault
If this warning light comes on,
accompanied by an audible
signal and a message on the
multi-function display, it indicates
a malfunction of the anti-lock braking sys-
tem which could result in loss of control of
the vehicle when braking.
If this warning light comes on,
together with the STOP and
ABS warning lights, accompa-
nied by an audible signal and a
message on the multifunction display, it
indicates a malfunction of the electronic
brake force distribution which could
result in loss of control of the vehicle
when braking.
You must stop as soon as it is safe
to do so.
Emergency braking assistance
System which, in an emergency, ena-
bles you to obtain the optimum braking
pressure more quickly, thus reducing
the stopping distance.
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. 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
i n b r a k i n g e f fi c i e n c y .
In both cases, contact a CITROËN
dealer. When braking in an emergency,
p r e s s fi r m l y w i t h o u t r e l e a s i n g t h e
pressure.

The ESP/ASR systems offer ex-
ceptional 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 recommen-
dations regarding the wheels (tyres
and rims), the braking components,
the electronic components and the
CITROËN assembly and operation
procedures.
After an impact, have these systems
checked by a CITROËN dealer.
Disarming
In exceptional conditions (starting a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to disarm the ASR and ESP
systems, so that the wheels can move
freely and regain grip.
Press the "ESP OFF" button, locat-
ed in the centre of the fascia.
If this warning light comes on on
the instrument panel and the in-
dicator light on the button comes
on, this indicates that the ASR
and ESP systems are disarmed.
Reactivation
These systems are reactivated automat-
ically each time the ignition is switched
b a c k o n o r f r o m 3 0 m p h ( 5 0 k m / h ) .
Press the "ESP OFF" button again
to reactivate them manually. Operating fault
If this warning light comes on,
accompanied by an audible sig-
nal and a message on the multi-
function display, this indicates a
malfunction of these systems.
Have the systems checked by a
CITROËN dealer.
TRAJECTORY CONTROL SYSTEMS
Activation
These systems are activated automati-
cally each time the vehicle is started.
They come into operation in the event
o f a g r i p o r t r a j e c t o r y p r o b l e m .
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation optimises trac-
tion to prevent skidding of the wheels,
by acting on the brakes of the driving
wheels and on the engine.
The electronic stability programme acts
on the brake of one or more wheels and
on the engine to keep the vehicle on the
