Braking assistance systems
Group of supplementary systems which help you to obtain optimum braking in complete
s
afety in emergency situations:
-
a
nti-lock braking system (ABS),
-
e
lectronic brake force distribution (EBFD),
-
e
mergency 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,
i
n particular on poor or slippery sur faces.
Activation
The anti-lock braking system comes into operation automatically when there is a risk of
w
heel lock.
Normal
operation of the ABS may make itself
f
elt by slight vibration of the brake pedal.
When
braking in an emergency, press
v
ery firmly without releasing the
p
ressure.
Operating fault
If this warning lamp comes on, together with the STOP and ABS
warning
lamps, accompanied by an
a
udible
signal and a message in the screen, it
i
ndicates
a malfunction of the electronic brake
f
orce 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
r
ims), ensure that they conform to the
ma
nufacturer's
r
ecommendations.
If
this warning lamp comes on,
a
ccompanied by an audible signal
a
nd a message in the screen, it

t
he
vehicle when braking.
In either case, contact a CITR
oË
N dealer or a
qualified
w
orkshop.

Emergency braking assistance
System which, in an emergency, enables you to obtain the optimum braking pressure more
q
uickly, 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
e
fficiency.
When
braking in an emergency, press
f
irmly without releasing the pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and electronic stability
programme (ESP)
The anti-slip regulation (also known as Traction Control) optimises traction to prevent skidding
o
f the wheels, by acting on the brakes of the
d
riving wheels and on the engine.
The
electronic stability programme acts on the
b
rake of one or more wheels and on the engine
t
o keep the vehicle on the trajectory required
b
y the driver, within the limits of the laws of
p
hysics.Activation
These systems are activated automatically each time the vehicle is started.
They
come into operation in the event of a grip
o
r
t
rajectory

blem.
This
is indicated by flashing of this
w
arning lamp in the instrument panel.
