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).

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
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

your seat belts checked regularly by
a
CITROËN dealer or a qualified workshop,
p
articularly if the straps show signs of

amage.
Clean the seat belt straps with soapy water or
a
textile cleaning product, sold by CITROËN
d

After
folding or moving a seat or rear bench

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.

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

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.

Front airbags
System which protects the driver and front passenger in the event of a serious front impact
i
n order to limit the risk of injury to the head and
c
hest.
The
driver's airbag is fitted in the centre of the
s
teering wheel; the front passenger's airbag is
f
itted in the dashboard above the glove box.deployment
The airbags are deployed, except the passenger's front airbag if it is deactivated,
i
n the event of a serious front impact applied
t
o all or part of the front impact zone A, in
the
longitudinal centreline of the vehicle on a
h
orizontal plane and directed from the front to
t
he rear of the vehicle.
The
front airbag inflates between the head-
thorax
of the front occupant of the vehicle
an
d the dashboard to cushion their forward
movement.
