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,
press very fi rmly without releasing
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 increase in braking effi ciency.

When braking in an emergency, press fi rmly without releasing the 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. This is indicated by fl ashing
of this warning lamp on the
instrument panel. Deactivation
In exceptional conditions (starting 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.
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.

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
multifunction screen:
- "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.
