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).
When braking in an emergency,
press very fi rmly without releas-
ing the pressure.
When replacing wheels (tyres
and rims), ensure that they con-
form to the manufacturer's rec-
ommendations.
When braking in an emergency,
press fi rmly without releasing
the pressure.
Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the sta-
bility and manoeuvrability of your vehi-
cle 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
If this warning lamp comes on,
accompanied by an audible
signal and a message in the
screen, it indicates a malfunc-
tion 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.
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.
In either case, contact a CITROËN
dealer or a qualifi ed workshop.
