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 
seats in the event of a front or side impact. 
Depending on the severity of the impact, the 
pretensioning system instantly tightens the seat 
belts against the body of the occupants.
The pretensioning seat belts are active when 
the ignition is on.
The force limiter reduces the pressure of the 
seat 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 
they will not fulfil their role fully.
The seat belts are fitted with an inertia reel 
permitting automatic adjustment of the length 
of the strap to your size. The seat belt is 
stowed automatically when not in use.
Before and after use, ensure that the seat 
belt is reeled in correctly.
The lower part of the strap must be 
positioned as low as possible on the pelvis.
The upper part must be positioned in the 
hollow of the shoulder.
The inertia reels are fitted with an automatic 
locking device which comes into operation in 
the event of a collision, emergency braking 
or if the vehicle rolls over. You can release 
the device by pulling the strap firmly and then 
releasing it so that it reels in slightly.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 
more than one person.
Never allow a child to travel on your lap.
For more information, refer to the "Child 
seats" section.
Advice
In order to be effective, a seat belt must:
- b e tightened as close to the body as 
possible,
-
 
b
 e pulled in front of you with a smooth 
movement, checking that it does not 
twist,
-
 
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 
affecting its performance.
In accordance with current safety regulations, 
for all repairs on your vehicle's seat belts, go 
to a qualified workshop with the skills and 
equipment needed, which a CITROËN dealer 
is able to provide.
Have your seat belts checked regularly by 
a CITROËN dealer or a qualified workshop, 
particularly if the straps show signs of 
damage.
Clean the seat belt straps with soapy water or 
a textile cleaning product, sold by CITROËN 
dealers.
After folding or moving a seat or rear bench 
seat, ensure that the seat belt is positioned 
and reeled in correctly.
In the event of an impact
depending on the nature and 
seriousness of the impact , the 
pretensioning device may be deployed 
before and independently of the airbags. 
Deployment of the pretensioners is 
accompanied by a slight discharge of 
harmless smoke and a noise, due to the 
activation of the pyrotechnic cartridge 
incorporated in the system.
In all cases, the airbag warning lamp 
comes on.
Following an impact, have the seat belts 
system checked, and if necessary replaced, 
by a CITROËN dealer or a qualified 
workshop.

Airbags
general information
System designed to contribute towards 
improving the safety of the occupants (with 
the exception of the rear centre passenger) 
in the event of violent collisions. The airbags 
supplement the action of the seat belts fitted 
with force limiters (all except the centre rear 
passenger belt).
If a collision occurs, the electronic detectors 
record and analyse the front and side impacts 
sustained in the impact detection zones:
- 
i
 n the case of a serious impact, the airbags 
are deployed instantly and contribute 
towards better protection of the occupants 
of the vehicle (with the exception of the 
rear centre passenger); immediately after 
the impact, the airbags deflate rapidly so 
that they do not hinder visibility or the exit 
of the occupants,
-
 
i
 n the case of a minor or rear impact or in 
certain roll-over conditions, the airbags 
may not be deployed; the seat belt 
alone contributes towards ensuring your 
protection in these situations. The airbags do not operate when the 
ignition is switched off.
This equipment will only deploy once. 
If a second impact occurs (during the 
same or a subsequent accident), the 
airbag will not be deployed again.
Impact detection zones
A. Front impact zone.
B. S
ide impact zone.
Deployment of one or more of the 
airbags is accompanied by a slight 
emission of smoke and a noise, due 
to the activation of the pyrotechnic 
cartridge incorporated in the system.
This smoke is not harmful, but sensitive 
individuals may experience slight 
irritation.
The noise of detonation related to the 
deployment of one or more airbags 
may result in a slight loss of hearing for 
a short time.

Front airbags
System which protects the driver and front 
passenger in the event of a serious front impact 
in order to limit the risk of injury to the head and 
thorax.
The driver's airbag is fitted in the centre of the 
steering wheel; the front passenger's airbag is 
fitted in the dashboard above the glove box.deployment
The airbags are deployed, except the 
passenger's front airbag if it is deactivated, in 
the event of a serious front impact to all or part 
of the front impact zone A, in the longitudinal 
centreline of the vehicle on a horizontal plane 
and directed from the front to the rear of the 
vehicle.
The front airbag inflates between the thorax 
and head of the front occupant of the vehicle 
and the steering wheel, driver's side, and the 
dashboard, passenger's side to cushion their 
for ward movement.

passenger in the event of a serious side impact 
in order to limit the risk of injury to the chest, 
between the hip and the shoulder.
Each lateral airbag is fitted in the seat backrest 
frame, door side.deployment
A lateral airbag is deployed unilaterally in the 
event of a serious side impact applied to all or 
part of the side impact zone B, perpendicular 
to the longitudinal centreline of the vehicle on a 
horizontal plane and directed from the outside 
towards the inside of the vehicle.
The lateral airbag inflates between the hip and 
shoulder of the front occupant of the vehicle 
and the corresponding door trim panel.

Curtain airbags
System which contributes towards improving the 
protection of the driver and passengers (with the 
exception of the rear centre passenger) in the 
event of a serious side impact in order to limit 
the risk of injury to the side of the head.
Each curtain airbag is built into the pillars and 
the upper passenger compartment area.
deployment
The curtain airbag is deployed at the same 
time as the corresponding lateral airbag in the 
event of a serious side impact applied to all or 
part of the side impact zone B, perpendicular 
to the longitudinal centreline of the vehicle on a 
horizontal plane and directed from the outside 
towards the inside of the vehicle.
The curtain airbag inflates between the front or 
rear occupant of the vehicle and the windows.

Advice
Front airbags
Do not drive holding the steering wheel by its 
spokes or resting your hands on the centre 
part of the wheel.
Passengers must not place their feet on the 
dashboard.
Do not smoke as deployment of the airbags 
can cause burns or the risk of injury from a 
cigarette or pipe.
Never remove or pierce the steering wheel or 
hit it violently.
Do not fit or attach anything to the steering 
wheel or dashboard, this could cause injuries 
with deployment of the airbags.
Lateral airbags
Use only approved covers on the seats, 
compatible with the deployment the lateral 
airbags. For information on the range of 
seat covers suitable for your vehicle, you 
can contact a CITROËN  dealer.
For more information on accessories, refer 
to the corresponding section.
Do not fix or attach anything to the seat 
backs (clothing...). This could cause injury 
to the chest or arms if the lateral airbag is 
deployed.
Do not sit with the upper part of the body 
any nearer to the door than necessary.
Sit in a normal upright position.
Wear a correctly adjusted seat belt.
Do not leave anything between the occupants 
and the airbags (a child, pet, object...), nor 
fix or attach anything close to the inflation 
trajectory of the airbags; this could cause 
injuries during their deployment.
Never modify the original definition of your 
vehicle, particularly in the area directly 
around the airbags.
After an accident or if the vehicle has been 
stolen or broken into, have the airbag 
systems checked.
All work on the airbag system must be 
carried out by a CITROËN dealer or a 
qualified workshop.
Curtain airbags
Do not fix or attach anything to the roof. 
This could cause injury to the head if the 
curtain airbag is deployed.
If fitted on your vehicle, do not remove the 
grab handles installed on the roof, they play 
a part in securing the curtain airbags.
Even if all of the precautions mentioned 
are observed, a risk of injury or of minor 
burns to the head, chest or arms when an 
airbag is deployed cannot be ruled out. The 
bag inflates almost instantly (within a few 
milliseconds) then deflates within the same 
time discharging the hot gas via openings 
provided for this purpose.
For the airbags to be fully effective, observe the safety recommendations below:
