BRAKING ASSISTANCE SYSTEMS
Group of supplementary systems
which help you to obtain optimum
braking in complete safety in emer-
gency situations:
- anti-lock braking system (ABS),
- electronic brake force distribu-tion (EBFD),
- emergency braking assistance (EBA).
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 surfaces.
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
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. If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multi-function screen,
it indicates a malfunction of the anti-
lock braking system which could re-
sult in loss of control of the vehicle
when braking.
If this warning lamp comes on,
together with the STOP and
ABS warning lamps, accom-
panied by an audible signal
and a message on the multifunction
screen, 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.
In both cases, contact a CITROËN
dealer.
When replacing wheels (tyres and
rims), ensure that they conform to the
manufacturer's recommendations. 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 i n c r e a s e i n b r a k i n g e f fi c i e n c y .
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.

TRAJECTORY CONTROL SYSTEMS
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation (also known
as Traction Control) 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 trajectory required
by the driver.
Activation
These systems are activated auto-
matically each time the vehicle is
started.
They come into operation in the event
of a grip or trajectory problem. T h i s i s i n d i c a t e d b y fl a s h i n g
of this warning lamp on the
instrument panel. Deactivation
I n e x c e p t i o n a l c o n d i t i o n s ( s t a r t i n g a
vehicle which is bogged down, stuck
in snow, on soft ground...), it may be
advisable to deactivate the ASR and
ESP systems, so that the wheels
can move freely and regain grip.
Press the "ESP OFF" button,
located in the centre of the dash-
board. Reactivation
These systems are reactivated au-
tomatically each time the ignition is
switched back on or from 30 mph
(50 km/h).
Press the "ESP OFF" button again
to reactivate them manually.
If this warning lamp comes
on in the instrument panel
and the indicator lamp on the
button comes on, this indi-
cates that the ASR and ESP
systems are deactivated. Operating fault
If this warning lamp comes
on, accompanied by an au-
dible signal and a message
on the multifunction screen,
this indicates a malfunction of these
systems.
Have the systems checked by a
CITROËN dealer.

ceptional safety in normal driving,
but this should not encourage the
d r i v e r t o t a k e e x t r a r i s k s o r d r i v e a t
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.

Dynamic emergency braking
In the event of a failure of the ve-
hicle’s main braking system or in
an exceptional situation (e.g. driver
taken ill, under instruction, etc) a
continuous pull on control A will stop
the vehicle.
The electronic stability programme
(ESP) provides stability during dy-
namic emergency braking.
If the dynamic emergency braking
malfunctions, one of the following
messages will be displayed on the
m u l t i f u n c t i o n s c r e e n :
- "Parking brake faulty".
- "Parking control faulty". If a failure of the ESP sys-
tem is signalled by the ligh-
ting of this warning lamp,
then braking stability is not
guaranteed. In this event, stability
must be assured by the driver by
repeating alternate "pull release" ac-
tions on control A .
The dynamic emergency
braking must only be used in
exceptional circumstances.

Emergency unlocking In the event of the electric parking
brake malfunctioning or the battery
r u n n i n g fl a t , a n e m e r g e n c y m e c h a -
nism can unlock the parking brake.
Immobilise the vehicle, with the
e n g i n e r u n n i n g , b y e n g a g i n g fi r s t
gear (manual gearbox), posi-
tion P (automatic gearbox) or M
or R (6-speed electronic gear-
box).
Switch off the engine, but leave
the ignition on.
If the vehicle cannot be immo- bilised, do not do anything and
contact a CITROËN dealer with-
out delay.
Fetch the vehicle blocks E and
the unlocking tool F (handle)
from the toolbox.
Immobilise the vehicle by placing
blocks E at the front and at the
rear of one of the rear wheels.
Slide the front left-hand seat
back as far as possible.
L i f t u p t h e fl o o r p l u g B
on the
carpet in front of the seat.
Pierce the tab C on the tube D
with the unlocking tool F .
Place the end of the handle F in
the tube D .
Turn the unlocking tool F clock-
wise.
For safety reasons , it is
essential to continue turning the
device as far as it will go or until
you hear a knocking noise. The
parking brake is released.
Remove the unlocking tool F and
store it with the blocks E in the
toolbox.
- The operation of the parking brake reinitialises when the ig-
nition is switched off then on
again. If the reinitialisation of the
parking brake proves impossi-
ble, contact a CITROËN dealer.
- The subsequent time required for application may be longer
than during normal operation.
For safety reasons, after this manoeuvre it is essential to cont act a CITROËN dealer urgently to have the plug
replaced.
Following an emergency unlocking, immobilisation of the vehi cle is no longer guaranteed once the manual emer-
gency unlocking has been deployed and the manual control doe s not allow the re-application of your parking
brake.
Take no action, either on control A , or stopping starting the engine while the unlocking to ol F is engaged.
Take care not to allow moisture or dust in the proximity of th e plug.
