Under-inflation alertReinitialisation
Before reinitialising the system, ensure
that the pressures of the four tyres are
correct for the use of the vehicle and in
line with the recommendations on the
tyre pressure label.
The under-inflation detection system
does not give a warning if a pressure is
incorrect at the time of reinitialisation.
This is given by fixed illumination of
this warning lamp, accompanied by
an audible signal and the display of a
message.
It is necessary to reinitialise the system every
time one or more tyre pressure is adjusted, and
after changing one or more wheels.
A label attached to the middle pillar, driver's
side, gives a reminder of this.

Dynamic stability control (DSC)
and anti-slip regulation (ASR)The DSC system offers exceptional
safety in normal driving, but this should
not encourage the driver to take extra
risks or drive at high speed.
The correct operation of the system
depends on observation of the
manufacturer's recommendations
regarding the wheels (tyres and rims),
the braking components, the electronic
components and the assembly and
repair procedures used by CITROËN
dealers.
After an impact, have the system
checked by a CITROËN dealer or a
qualified workshop.
Activation
These systems are activated automatically
each time the vehicle is started.
As soon as they detect a problem of grip or
trajectory, these systems act on the operation if
the engine and brakes.
Deactivation
In exceptional conditions (starting a vehicle
which is bogged down, stuck in snow, on soft
ground...), it may be advisable to deactivate
the DSC system, so that the wheels can move
freely and regain grip.
This is indicated by flashing of this
warning lamp in the instrument panel.

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 firmly on the strap and
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.
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,
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.
