Active City Brake
Active City Brakeis a driving assistance system that aims to avoid a frontal collision or reduce
t
he speed of an impact if the driver does
n
ot take sufficient action (inadequate brake
a
pplication).
This system is designed to improve driving safety.
I t remains the driver's responsibility to c
ontinuously monitor the state of the traffic and
t
o assess the distances and relative speeds of
other
v
ehicle.
Active City Brakecan in no circumstances replace the need for vigilance on the part of t
he
d
river.
never look at the laser sensor through an optical 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 Brakeonly 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.

Operating limits
The system only detects vehicles that are stationary or moving in the same direction as
y
our vehicle.
It
does not detect small vehicles
(
bicycles, motorcycles), pedestrians or
a
nimals, nor non-reflective stationary
ob
jects. In difficult weather conditions (very
heavy
rain, snow, fog, hail...), braking
d
istances increase, which can reduce
the
ability of the system to avoid a
c
ollision.
The
driver must therefore remain
par
ticularly
v
igilant.
Never
leave accumulations of snow or
a
ny object projecting above the bonnet
o
r in front of the roof: this might fall into
t
he field of vision of the sensor and
generate
a detection.
The
system is not triggered or is interrupted if t
he d river:
-
a
ccelerates strongly
-
o
r turns the steering wheel suddenly
(
avoiding
m
anoeuvre).

Operating faults
In the event of an impact to the windscreen at the sensor, deactivate
the
system and contact a CITROËN
d
ealer or a qualified workshop to have
y
our windscreen replaced.
Never
try to remove, adjust or test
t
he sensor.
on
ly a CITR
oË
N dealer or a qualified
workshop
is able to work on the system.
When
towing a trailer or when the
v
ehicle is being towed, the system must
b
e deactivated.
Do not stick or other wise fix any object on the windscreen in front of the sensor.
Sensor fault
The operation of the laser sensor may suffer inter ference from accumulations of dirt or
m
isting of the windscreen. In this case you are
w
arned by the display of a message.
Use
the windscreen demisting and regularly
c
lean the area of the windscreen in front of the
sensor.
System fault
In the event of a malfunction of the system, you a re warned by an audible signal and the display
o
f the message "Automatic braking system
fault" .
Have
the system checked by a CITROËN
d
ealer or a qualified workshop.

RAcING towbar
Your vehicle cannot be fitted with a
towbar. The space occupied by the
s
port diffuser prevents this.
Ty r e s
F Check the tyre pressures of the towing v
ehicle and of the trailer, observing the
re
commended
p
ressures.
cooling
Towing a trailer on a slope increases the temperature of the coolant.
As
the fan is electrically controlled, its cooling
c
apacity is not dependent on the engine speed.
F
T
o lower the engine speed, reduce your
s
peed.
The
maximum towed load on a long incline
d
epends on the gradient and the ambient
t
emperature.
In
all cases, keep a check on the coolant
t
emperature.
Braking
Towing a trailer increases the braking distance.
T o avoid overheating of the brakes on a long
m
ountain type of descent, the use of engine
b
raking is recommended.
Lighting
F Check the electrical lighting and signalling o
n the trailer.
The
rear parking sensors will be
d
eactivated automatically if a genuine
