Child safety




Advice on child seats

The incorrect installation of a child seat in avehicle compromises the child's protectionin the event of an accident.
Remember to fasten the seat belts or the child seat harnesses keeping the slack relative to the child's body to a minimum, even for shor t journeys.
When installing a child seat using the seat belt, ensure that the seat belt is tightenedcorrectly on the child seat and that it secures the child seat firmly on the seat of your vehicle. If your passenger seat isadjustable, move it for wards if necessary.
For optimum installation of the "for wards-facing" child seat, ensure that the back of the child seat is in contact with the back of the vehicle's seat and that the head restraint does not cause any discomfort.
If the head restraint has to be removed, ensure that it is stored or attached securely to prevent it from being thrown around the vehicle in the event of sharp braking.
Children under the age of 10 must not travel in the "forwards-facing" position on the front passenger seat, unless the rear seats are already occupied by other children, cannot be used or are absent.
Deactivate the passenger airbag when a "rearwards-facing" child seat is installed on the front seat. Other wise, the child would risk beingseriously injured or killed if the airbag were to inflate.
Installing a booster seat
The chest par t of the seat belt must bepositioned on the child's shoulder without touching the neck.
Ensure that the lap part of the seat belt passes correctly over the child's thighs.CITROËN recommends the use of abooster seat which has a back, fitted with aseat belt guide at shoulder level.

As a safety precaution, do not leave: - a child or children alone and unsuper vised in a vehicle, - a child or an animal in a vehicle which is exposed to the sun, with the windowsclosed, - the keys within reach of children inside the vehicle.To prevent accidental opening of the doors and rear windows, use the "Child lock". Take care not to open the rear windows bymore than one third.To protect young children from the rays of the sun, fit side blinds on the rear windows.

Braking assistance systems
Group of supplementary systems which helpyou to obtain optimum braking in complete safety in emergency situations:
- anti-lock braking system (ABS),
- electronic brake force distribution
(EBFD),
- emergency braking assistance (EBA).

Anti-lock braking system
and electronic brake force
distribution
Linked systems which improve the stability and
manoeuvrability of your vehicle when braking,
in par ticular on poor or slippery surfaces.
Activation
The anti-lock braking system comes into
operation automatically when there is a risk of
wheel lock.
Normal operation of the ABS may make itself
felt by slight vibration of the brake pedal.
When braking in an emergency, pressvery firmly without releasing thepressure.


Operating fault
If this warning lamp comes on,
together with the STOPand ABSwarning lamps, accompanied by an
audible signal and a message in the screen, it
indicates a malfunction of the electronic brake force distribution which could result in loss of control of the vehicle when braking.You must stop as soon as it is safe to do so.

When replacing wheels (tyres andrims), ensure that they conform to themanufacturer's recommendations.
If this warnin
g lamp comes on,
accompanied by an audible signaland a message in the screen, it
indicates a malfunction of the anti-lock brakingsystem which could result in loss of control of
the vehicle when braking.
In either case, contact a CITROËN dealer or a
qualified workshop.
