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
c
ontrol
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.

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
r
esistance of the pedal and an increase in
b
raking
e
fficiency.
When
braking in an emergency, press
f
irmly without releasing the pressure.
Trajectory control systems
Anti-slip regulation (ASR)
and dynamic stability
control (
d
SC)
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 control acts on the
brake
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

Active City Brake
Active City Brake is a driving assistance system that aims to avoid a frontal collision
o
r reduce the speed of an impact if the driver
d
oes not react sufficiently (inadequate brake
a
pplication). This
system is designed to improve
d
riving safety.
It
remains the driver's responsibility to
c
ontinuously monitor the state of the
t
raffic and to assess the distances and
r
elative speeds of other vehicles.
Active
City Brake can in no
c
ircumstances replace the need for
v
igilance on the part of the driver.
Never
look at the laser sensor through
an o
ptical
in
strument
(
magnifying
g
lass,
m
icroscope...) at a distance of less than
1
0 centimetres: risk of eye injury.Automatic
braking occurs later than if
d
one by the driver, so as to intervene
o
nly when there is a high risk of
c
ollision.Principle
Using a laser sensor located at the top of the windscreen, this system detects a vehicle
r
unning in the same direction or stationary
a
head of your vehicle.
When
necessary, the vehicle's braking system
i
s operated automatically to avoid a collision
w
ith the vehicle ahead.
Conditions for activation
Active City Brake only operates if the following conditions are met:
●
i
gnition on,
●
t
he vehicle is in a for ward gear,
●
s
peed is between about 3 and 18 mph
(5
and 30 km/h),
●
t
he braking assistance systems (ABS,
E
BFD, emergency braking assistance) are
n
ot faulty,
●
t
he trajectory control systems (ASR, DSC)
a
re not deactivated or faulty,
●
t
he vehicle is not in a tight corner,
●
t
he system has not been triggered during
t
he previous 10 seconds.
Safety

Operation
When your vehicle is too close to or
approaches the vehicle ahead too quickly the
s
ystem automatically applies the brakes to
a
void a collision.
The
collision can be avoided automatically if the
d
ifference in speed between your vehicle and the
v
ehicle ahead does not exceed 9 mph (15 km/h).
Above
this threshold, the system will do what
i
s possible to avoid or reduce the accident by
l
owering the speed of impact.
The
automatic braking may bring the vehicle to
a
complete stop if the situation requires it.
In
this case, the vehicle is held stationary
t
emporarily (for about 1.5 seconds) to allow
t
he driver to take back control by pressing the
b
rake
ped
al.
You
are then alerted by the display of a
m
essage.
The
brake lamps on your vehicle come on to
w
arn other road users.
After
an impact, the system is
a
utomatically put out of service: it no
lon
ger
ope
rates.
You
must go to a CITROËN dealer or a
q
ualified workshop to have the system
m
ade operational again.
During
automatic braking, the driver
c
an always obtain a higher rate of
d
eceleration than that controlled by the
s
ystem, by pressing firmly on the brake
ped
al.
The
triggering of the system may cause
t
he engine to stall, unless the driver
d
epresses the clutch pedal quickly
e
nough during automatic braking.
deactivation
The system is deactivated in the vehicle configuration menu, accessible with the ignition
o
n.
Its
state is memorised when the ignition is
s
witched off. When
the system is deactivated, a
m
essage is displayed every time the
i
gnition is switched on, to warn you.
