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

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
o
ther
v
ehicle.
Active
City Brakecan in no circumstances replace
t
he need for vigilance 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 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.

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.

163
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
h
eavy rain, snow, fog, hail...), braking
d
istances increase, which can reduce
t
he 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
g
enerate 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).

Seat belts
Front seat belts
The front seat belts are fitted with a pretensioning and force limiting system.
This
system improves safety in the front
s
eats in the event of a front or side impact.
D
epending on the severity of the impact, the
p
retensioning system instantly tightens the seat
b
elts against the body of the occupants.
The
pretensioning seat belts are active when
t
he ignition is on.
The
force limiter reduces the pressure of the
s
eat belt on the chest of the occupant, so
improving
their protection.

The driver must ensure that passengers use the seat belts correctly and that they are all
r
estrained securely before setting off.
Wherever
you are seated in the vehicle,
a
lways 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
p
ermitting automatic adjustment of the length
o
f the strap to your size. The seat belt is
s
towed automatically when not in use.
Before
and after use, ensure that the seat
b
elt 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

In the event of an impact
depending on the nature and
seriousness of the impact , the
pretensioning
device may be deployed
b
efore and independently of the airbags.
D
eployment of the pretensioners is
a
ccompanied 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.
