Under-inflation detection
The system monitors the pressures in the four
tyres, once the vehicle is moving.
It compares the information given by the four
wheel speed sensors with reference values,
which must be reinitialised ever y time the
tyre pressures are adjusted or a wheel
changed.
The system triggers an alert as soon as it
detects a drop in the inflation pressure of one
or more tyres. The under-inflation detection system
does not replace the need for vigilance
on the part of the driver.
This system does not avoid the need to
check the tyre pressures (including the
spare wheel) every month as well as
before a long journey.
Driving with under-inflated tyres impairs
road holding, extends braking distances
and causes premature tyre wear,
particularly under arduous conditions
(high loading, high speed, long journey).
System which automatically checks the pressures of the tyres while driving.
The inflation pressures defined for
your vehicle can be found on the tyre
pressure label.
For more information on the
Identification markings, refer to the
corresponding section.
Driving with under-inflated tyres
increases fuel consumption. Checking tyre pressures
This check should be done when the
tyres are "cold" (vehicle stopped for
1
hour or after a journey of less than
6
miles (10 km) at moderate speeds).
Other wise, add 0.3 bar to the pressures
shown on the label.

General safety recommendations
Labels are applied at various
points on your vehicle. They carry
safety warnings as well as vehicle
identification information. Do not
remove them: they form an integral part
of your vehicle.
For any work on your vehicle, use
a qualified workshop that has the
technical information, skills and
equipment required, all of which a
CITROËN dealer is able to provide.We draw your attention to the following points:
- The fitting of electrical equipment or accessories not listed by CITROËN may cause
excessive current consumption and faults and failures with the electrical system of
your vehicle. Contact a CITROËN dealer for information on the range of recommended
accessories.
-

A
s a safety measure, access to the diagnostic socket, used for the vehicle's electronic
systems, is reserved strictly for CITROËN dealers or qualified workshops, equipped
with the special tools required (risk of malfunctions of the vehicle's electronic systems
that could cause breakdowns or serious accidents). The manufacturer cannot be held
responsible if this advice is not followed.
-

A
ny modification or adaptation not intended or authorised by Automobiles CITROËN
or carried out without meeting the technical requirements defined by the manufacturer
would lead to the suspension of the legal and contractual warranties.
Installation of accessory radio communication transmitters
Before installing a radio communication transmitter, you must contact a CITROËN dealer
for the specification of transmitters which can be fitted (frequency, maximum power,
aerial position, specific installation requirements), in line with the Vehicle Electromagnetic
Compatibility Directive (2004/104/EC).
Depending on the legislation in force in the country, certain safety equipment may be
compulsory: high visibility safety vests, warning triangles, breathalysers, spare bulbs, spare
fuses, fire extinguisher, first aid kit, mud flaps at the rear of the vehicle...

Safety

237
The driver must ensure that passengers use
the seat belts correctly and that they are all
fastened 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 fulfill 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 on Child seats, refer
to the corresponding section.
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 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.
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.

Lateral airbags
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. System which protects the driver and front
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.In the event of a minor impact or bump
on the side of the vehicle or if the
vehicle rolls over, the airbags may not
be deployed.
In the event of a rear or front collision,
none of the lateral airbags is deployed.
System contributing towards greater protection
for 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.
Curtain airbags
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.
If this warning lamp comes on in the
instrument panel, you must contact
a CITROËN dealer or a qualified
workshop to have the system checked.
Operating fault
The airbags may no longer be deployed in the
event of a serious impact.
