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
i

a malfunction of the anti-lock braking
s
ystem
which could result in loss of control of
t
he
vehicle when braking.
In either case, contact a CITROËN dealer or a

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
relative
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
only
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.
