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.
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
vehicle
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
lowering
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
temporarily
(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
message.
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
system,
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.

The driver must ensure that passengers use the seat belts correctly and that they are all
restrained
securely before setting off.
Wherever you are seated in the vehicle,
always fasten your seat belt, even for short
journeys.
Do
not interchange the seat belt buckles as
t
hey will not fulfil their role fully.
The seat belts are fitted with an inertia reel
permitting
automatic adjustment of the length
o
f the strap to your size. The seat belt is
s
towed automatically when not in use.
be
fore and after use, ensure that the seat
belt
is reeled in correctly.
The
lower part of the strap must be
p
ositioned as low as possible on the pelvis.
The
upper part must be positioned in the
h
ollow of the shoulder.
The
inertia reels are fitted with an automatic
l
ocking device which comes into operation in
t
he event of a collision, emergency braking
o
r if the vehicle rolls over. You can release
t
he device by pulling the strap firmly and then
r
eleasing it so that it reels in slightly.In
order to be effective, a seat belt must:
- b e tightened as close to the body as
p
ossible,
-
b
e pulled in front of you with a smooth
m
ovement, checking that it does not
t
wist,
-
b
e used to restrain only one person,
-
n
ot bear any trace of cuts or fraying,
-
n
ot be converted or modified to avoid

r
egulations,
f
or all repairs on your vehicle's seat belts, go
t
o a qualified workshop with the skills and
e
quipment needed, which a CITROËN dealer
i
s able to provide.
Have
your seat belts checked regularly by
a
CITROËN dealer or a qualified workshop,
p
articularly if the straps show signs of
d
amage.
Clean the seat belt straps with soapy water or
a
textile cleaning product, sold by CITROËN
d
ealers.
After
folding or moving a seat or rear bench
s
eat, ensure that the seat belt is positioned
and
reeled in correctly.Recommendations for
children
Use a suitable child seat if the passenger is less than 12 years old or shorter than one
and
a half metres.
Never
use the same seat belt to secure
m
ore than one person.
Never
allow a child to travel on your lap.

ction.
In the event of an impact
depending on the nature and seriousness
of the impact ,
the pretensioning device may
b
e deployed before and independently of the
airbags.
Deployment of the pretensioners
i
s accompanied by a slight discharge of
h
armless smoke and a noise, due to the
a
ctivation of the pyrotechnic cartridge
i
ncorporated in the system.
In
all cases, the airbag warning lamp comes on.
Following
an impact, have the seat belts
s
ystem checked, and if necessary replaced,
b
y a CITR
oË
N dealer or a qualified
workshop.

Airbags
System designed to contribute towards improving the safety of the occupants (with
t
he exception of the rear centre passenger)
i
n the event of violent collisions. The airbags
s
upplement the action of the force-limiting
s
eat belts (with the exception of the centre rear
p
assenger).
If a collision occurs, the electronic detectors
record
and analyse the front and side impacts
s
ustained in the impact detection zones:
-
i
n the case of a serious impact, the airbags
a
re deployed instantly and contribute
towards better protection of the occupants
of
the vehicle (with the exception of the
r
ear centre passenger); immediately after
t
he impact, the airbags deflate rapidly so
t
hat they do not hinder visibility or the exit
o
f the occupants,
-
i
n the case of a minor or rear impact or in
c
ertain roll-over conditions, the airbags
m
ay not be deployed; the seat belt
a
lone contributes towards ensuring your
p
rotection in these situations. This
equipment will only deploy once.
I
f a second impact occurs (during the
s
ame or a subsequent accident), the
a
irbag will not be deployed again.
Impact detection zones
A. Front impact zone.
B. S ide impact zone.
Deployment
of one or more of the
a
irbags is accompanied by a slight
e
mission of smoke and a noise, due
t
o the activation of the pyrotechnic
cartridge
incorporated in the system.
This
smoke is not harmful, but sensitive
i
ndividuals may experience slight
ir
ritation.
The noise of detonation related to the
deployment
of one or more airbags
m
ay result in a slight loss of hearing for
a
short time.
The airbags do not operate when the
ignition is switched off.
Safety

For the airbags to be fully effective, observe the following safety rules:Front airbags
Do not drive holding the steering wheel by its spokes or resting your hands on the centre
p
art of the wheel.
Passengers
must not place their feet on the
das
hboard.
Do
not smoke as deployment of the airbags

an cause burns or the risk of injury from a
c
igarette or pipe.
Never
remove or pierce the steering wheel or
h
it it violently.
Do
not fit or attach anything to the steering
w
heel or dashboard, this could cause injuries
w
ith deployment of the airbags.
Lateral airbags
Use only approved covers on the seats,
compatible with the deployment the lateral
a
irbags. For information on the range of seat
c
overs suitable for your vehicle, you can
contact
a CITROËN dealer.
Refer
to the "Accessories" section.
Do
not fix or attach anything to the seat
b
acks (clothing...). This could cause injury
t
o the chest or arms if the lateral airbag is
d
eployed.
Do not sit with the upper part of the body any
nearer
to the door than necessary.
curtain airbags
Do not fix or attach anything to the roof. This could cause injury to the head if the
c
urtain airbag is deployed.
If
fitted on your vehicle, do not remove the
g
rab handles installed on the roof, they play
a
part in securing the curtain airbags.

General points relating to child seats
Although one of CITROËN main criteria when designing your vehicle, the safety of your children also depends on you.
cI
TROËN recommends that children
should travel on the rear seats of your
vehicle:
-
"rearward-facing" up to the age of 3,- "forward-facing" over the age of 3.
For maximum safety, please observe the f
ollowing r ecommendations:
-
i
n accordance with European regulations,
a
ll children under the age of 12 or less
than one and a half metres tall must
travel in approved child seats suited to
their weight , on seats fitted with a seat
belt
or ISOFIX mountings*,
-
s
tatistically, the safest seats in your
vehicle for carr ying children are the
rear seats,
-
a c
hild weighing less than 9 kg must
travel in the "rear ward facing" position
both in the front and in the rear.
*
T
he regulations on carrying children are
s
pecific to each country. Refer to the
l
egislation in force in your country.
