SAFETY
BRAKING ASSISTANCE
SYSTEMS
Group of supplementary systems which
help you to obtain optimum braking in
complete safety in emergency situa-
tions:
- anti-lock braking system (ABS),
- electronic brake force distribution (EBFD),
- emergency braking assistance (EBA).
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the sta-
bility 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.
When braking in an emergency,
press very fi rmly without releas-
ing the pressure. Operating fault
In either case, contact a CITROËN dealer.
If this warning lamp comes on,
accompanied by an audible sig-
nal and a message on the mul-
tifunction screen, 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 lamp comes on,
together with the STOP and

ABS warning lamps, accompa-
nied by an audible signal and a
message on the multifunction screen, it
indicates a malfunction of the electron-
ic 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.
When replacing wheels (tyres
and rims), ensure that they
conform to the manufacturer's
recommendations. 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
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.

SAFETY
TRAJECTORY CONTROL
SYSTEMS
Anti-skid regulation (ASR) and
electronic stability programme
(ESP)
The anti-skid regulation (also known as
Traction Control) optimises traction to
prevent skidding of the wheels, by act-
ing 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 automati-
cally 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 instru-
ment panel. Deactivation
In exceptional conditions (starting a ve-
hicle which is bogged down, stuck in
snow, on soft ground...), it may be ad-
visable to deactivate the ASR and ESP
systems, so that the wheels can move
freely and regain grip.

 Press the "ESP OFF" button, located
on the left below the steering wheel.
If this warning lamp comes on in
the instrument panel and the in-
dicator lamp on the button comes
on, this indicates that the ASR and
ESP systems are deactivated.
Reactivation
These systems are reactivated automat-
ically 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. Operating fault
If this warning lamp comes on,
accompanied by an audible sig-
nal and a message on the mul-
tifunction 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 proce-
dures.
After an impact, have these sys-
tems checked by a CITROËN
dealer.
