Reinitialisation of the system is done with the ignition on and the vehicle stationary.
From the secondary page of the " Drivingassistance" menu:
)Press " Under-inflation initialisation".
)
Confirm the instruction by pressing "Yes".


The new pressure settings registered are considered to be reference values by the
system.


Operating fault

The flashing and then fixed illumination of the
under-inflation warning lamp accompanied
by illumination of the "ser vice" warning lamp
indicates a fault with the system.
In this case, under-inflation monitorin
g of the
tyres is no longer assured.
Have the system checked by a CITROËN
dealer or a qualified workshop.

Before doing anything to the system,the pressures of the four tyres must bechecked and the system reinitialised.

The under-inflation aler t can only beconsidered reliable if reinitialisation of the system is done with the the four tyrepressures correctly set.



Snow chains
The system does not have to be reinitialised after fitting or removingsnow chains.


Before reinitialising the system, ensure that the pressures of the four tyres arecorrect for the use of the vehicle and inline with the recommendations on thetyre pressure label.
The under-inflation detection systemdoes not give a warning if a pressure isincorrect at the time of reinitialisation.

Safety
Intelligent traction control
s
ystem ("Snow motion")
When this warning lamp comes on,coupled with the STOPwarning lamp,
accompanied by an audible signal and a
message, it indicates that there is a fault
with the electronic brake force distribution(EBFD), which could cause loss of control of the vehicle when braking.

Operation
When this warning lamp comes on,
accompanied by an audible signaland a message, it indicates that there
is a fault with the ABS, which could cause loss of control of the vehicle
when braking.
Your vehicle has a system to help driving onsnow: intelligent traction control.This system detects situations of difficult surface adhesion that could make it difficult to move off or make progress on deep fresh snow
or compacted snow.
In these situations
, the intelligent traction control limits the amount of wheel slip to provide the best traction and trajectory controlfor your vehicle.
In extremely severe conditions (deep snow,mud, ...), when it proves impossible to move off,
it may be useful to temporarily deactivate theESP/ASR systems to allow the wheels to spin
freely and so allow movement of the vehicle.
The use o
f snow tyres is strongly recommended on sur faces offering low levels of adhesion.

Anti-lock braking system (ABS)
and electronic brake force
distribution
(EBFD)

When changing wheels (tyres and rims),make sure that these are approved for your vehicle.
Normal operation of the ABS may make itself felt by slight vibrations of the brake pedal.
In emergency braking, press very firmly without releasing the pressure.
You must stop as soon as it is safe to do so.
In both cases, contact a CITROËN dealer or a qualified workshop.

Dynamic stability control(DSC)


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 obser vation of the manufacturer's recommendationsregarding the wheels (tyres and rims),the braking components, the electronic components and the assembly andrepair procedures used by CITROËNdealers.
After an impact, have the systemchecked by a CITROËN dealer or a qualified workshop.

Safety
The driver must ensure that passengers usethe seat belts correctly and that they are allrestrained 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 isstowed automatically when not in use.
Before and after use, ensure that the seatbelt is reeled in correctly.
The lower par t of the strap must be positioned as low as possible on the pelvis.
The upper par t must be positioned in the hollow of the shoulder.
The inertia reels are fitted with an automatic locking device which comes into operation inthe 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 shor ter 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:


- be tightened as close to the body as possible,


- be pulled in front of you with a smooth movement, checking that it does nottwist,

- be used to restrain only one person,

- not bear any trace of cuts or fraying,

- not be converted or modified to avoidaffecting its per formance.
In the event of an impact
Depending on the nature and seriousness of the impact
, thepretensioning device may be deployedbefore and independently of the airbags.Deployment of the pretensioners isaccompanied by a slight discharge of harmless smoke and a noise, due to theactivation of the pyrotechnic car tridge incorporated in the system. In all cases, the airbag warning lampcomes 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 soapywater or a textile cleaning product, sold byCITROËN dealers.
After folding or moving a seat or rear bench seat, ensure that the seat belt is positioned and reeled in correctly.
