SAFETY
BRAKING ASSISTANCE SYSTEMS
Group of supplementary systems which
help you to obtain optimum braking in
complete safety in emergency situations:
- 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 or a qualifi ed workshop.
If this warning lamp comes on,
accompanied by an audible
signal and a message in the
screen, it indicates a malfunction of the
anti-lock braking system 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
in the 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.
When replacing wheels (tyres
and rims), ensure that they
conform to the manufacturer's
recommendations.
Emergency braking assistance
System which, in an emergency, en-
ables 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.
EMERGENCY OR ASSISTANCECALL
This system allows you to make an
emergency or assistance call to the
emergency services or to the dedicated
CITROËN service.
For more information on the use of this
function, refer to the "Audio and tele-
matics" section.

SAFETY
TRAJECTORY CONTROLSYSTEMS
Anti-slip re
gulation (ASR) and
electronic stability programme (ESP)
The anti-slip regulation (also known
as Traction Control) optimises traction
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, within
the limits of the laws of physics.
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 in the instru-
ment panel.
Deactivation
In exceptional conditions (starting a ve-
hicle which is bogged down, stuck in
snow, on soft ground...), if you are un-
able to make progress, it may be ad-
visable to temporarily deactivate these
systems, so that the wheels can spin
freely and allow the vehicle to move.
)
Press the "ESP OFF"
button, located
near the steering wheel.
If this warning lamp comes on
in the instrument panel and
the indicator lamp in the button
comes on, this indicates that
these systems are deactivated.
It is recommended that the systems be
reactivated as soon as possible.
Reactivation
These systems are reactivated automa-
tically 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
signal and a message in the
screen, this indicates a fault
with these systems.
Have it checked by a CITROËN dealer
or a qualifi ed workshop.
The trajectory control systems
offer increased safety in normal
driving, but this should not en-
courage the driver to take extra
risks or drive at high speed.
The correct functioning of these
systems is assured provided
that manufacturer's recommen-
dations are observed on:
- wheels (tyres and rims),
- braking components,
- electronic components,
- assembly and repair proce-
dures.
After an impact, have these sys-
tems checked by a CITROËN
dealer or a qualifi ed workshop.
