165Child safety
Advice on child seats
The incorrect installation of a child seat in a
vehicle compromises the child's protection
in 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 tightened
correctly on the child seat and that it
secures the child seat firmly on the seat
of your vehicle. If your passenger seat is
adjustable, 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 discomfor t.
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 "for wards-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
"rear wards-facing" child seat is installed on
the front seat.
Other wise, the child would risk being
seriously injured or killed if the airbag were
to inflate.
Installing a booster seat
The chest par t of the seat belt must be
positioned 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 a
booster seat which has a back, fitted with a
seat 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 windows
closed,
- 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 by
more 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 help
you 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 sur faces.
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, press
very firmly without releasing the
pressure.
Operating fault
If this warning lamp comes on,
together with the STOP
and ABS
warning 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 and
rims), ensure that they conform to the
manufacturer's recommendations.
If this warning lamp comes on,
accompanied by an audible signal
and a message in the screen, it
indicates a malfunction of the anti-lock braking
system which could result in loss of control of
the vehicle when braking.
In either case, contact a CITROËN dealer or a
qualified workshop.
