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 in
relation to the child's body to a minimum,
even for short journeys.
For optimum installation of the for ward
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.
Advice on child seats
Installing a booster cushion
The chest part 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:
-

o
ne or more children alone and
unsupervised in a vehicle,
-

a c
hild or an animal in a vehicle which
is exposed to the sun, with the windows
closed,
-

t
he keys within reach of children inside
the vehicle.
Children at the front
The legislation on carrying a child on the
front passenger seat is specific to each
country. Refer to the legislation in force in
your country.
Deactivate the passenger's airbag when a
rear ward 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.
To prevent accidental opening of the doors,
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.
