ANTI-LOCK BRAKING SYSTEM
(ABS - EBFD)
The ABS and EBFD (electronic brake
force distribution) systems improve the
stability and manoeuvrability of your
vehicle on braking, in particular on
poor or slippery surfaces.
The ABS prevents locking of the
wheels, the EBFD provides control of
the braking pressure wheel by wheel. If this warning lamp comes
on, accompanied by an
audible signal and a message
in the screen, it indicates a
malfunction of the ABS which
could result in a loss of control of the
vehicle on braking.
If this warning lamp comes
on, together with the brake
and STOP warning lamps,
accompanied by an audible
signal and a message in the
screen, it indicates a malfunction of
the electronic brake force distribution
which could result in a loss of control of
the vehicle on braking.
EMERGENCY BRAKING
ASSISTANCE SYSTEM (EBA)
In an emergency, this system enables
the optimum braking pressure to be
reached more quickly, press the pedal
fi rmly without releasing it.
It is triggered by the speed at which the
brake pedal is activated.
This alters the resistance of the brake
pedal under your foot.
To prolong the operation of the
emergency braking assistance system:
keep your foot on the brake pedal.
Good practice
The anti-lock braking system comes
into operation automatically when
there is a risk of wheel lock. It does not
reduce the braking distance.
On very slippery surfaces (ice, oil,
etc...) the ABS may increase the
braking distance. When braking in
an emergency, do not hesitate to
press the brake pedal fi rmly, without
releasing the pressure, even on a
slippery surface, you will then be able
to continue to manoeuvre the vehicle
to avoid an obstacle.
Normal operation of the ABS may be
felt by slight vibration of the brake
pedal.
When changing wheels (tyres
and rims), ensure that these are
recommended by CITROËN. Stop as soon as it is safe to do so.
In both cases, contact a CITROËN
dealer or a qualifi ed workshop.

ANTI-SLIP REGULATION (ASR)
AND DYNAMIC STABILITY
CONTROL (DSC)
These systems are linked and
complement the ABS.
The ASR system is very useful for
maintaining optimum drive and
avoiding losses of control of the vehicle
on acceleration.
The system optimises drive to prevent
the wheels skidding, by acting on the
brakes of the drive wheels and on the
engine. It also allows the directional
stability of the vehicle to be improved
on acceleration.
Use the DSC to hold your course
without attempting to countersteer.
If there is a variation between the
trajectory followed by the vehicle and
that required by the driver, the DSC
system automatically acts on the
engine and the brake of one or more
wheels, in order to put the vehicle back
on course.
Deactivating the ASR/DSC
systems
In certain exceptional conditions
(starting the vehicle when stuck in mud
or snow, or on loose ground...), it could
prove useful to deactivate the ASR and
DSC systems to make the wheels spin
and regain grip. Operating check
Good practice
The ASR/DSC systems offer increased
safety during normal driving, but
should not incite the driver to take risks
or to drive at high speed.
The operation of these systems is
ensured if the recommendations
of the manufacturer regarding
the wheels (tyres and rims), the
braking components, the electronic
components and the fi tting and repair
procedures within the CITROËN
network are observed.
After an impact, have these systems
checked by a CITROËN dealer or a
qualifi ed workshop.
Operation of the ASR and
DSC systems
The LED fl ashes when the
ASR or DSC is triggered.
They engage again:
- automatically above 30 mph (50 km/h), When a malfunction of the
systems occurs, the warning
lamp comes on, accompanied
by an audible signal and a
message in the screen.
Contact a CITROËN dealer or a
qualifi ed workshop to have the system
checked.
The warning lamp may also come on if
the tyres are under-infl ated. Check the
pressure of each tyre.
- Press the button or turn the dial to the DSC OFF
position (depending on
model).
- The warning lamp comes on: the ASR and DSC systems no longer
come into play.
- manually by pressing the button again or by turning
the dial to this position
(depending on model).
