Safety  
Advice  
The incorrect installation of a child seat in a  
vehicle compromises the child's protection  
in the event of an accident.  
Ensure that there is no seat belt or seat belt  
buckle under the child seat, as this could  
destabilise it.  
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 short 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 forwards if necessary.  
For optimum installation of the forward  
facing child seat, ensure that the back of  
the child seat is as close as possible to the  
backrest of the vehicle's seat, in contact if  
possible.  
You must remove the head restraint before  
installing a child seat with backrest to a  
passenger seat.  
Ensure that the head restraint is stored or  
attached securely to prevent it from being  
thrown around the vehicle in the event of  
sharp braking. Refit the head restraint when  
the child seat is removed.  
Installing a booster seat  
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:  
-
a child or children alone and  
unsupervised in a vehicle,  
a child or an animal in a vehicle which  
is exposed to the sun, with the windows  
closed,  
-
Children at the front  
The legislation on carrying children on the  
front passenger seat is specific to each  
country. Refer to the legislation in force in  
your country.  
Deactivate the passenger's front airbag  
when a rearward facing child seat is  
installed on the front passenger seat.  
Otherwise, the child risks being seriously  
injured or killed if the airbag is deployed.  
-
the keys within reach of children inside  
the vehicle.  
At rear seating positions, always leave  
sufficient space between the front seat and:  
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.  
-
-
a rearward facing child seat,  
the child's feet for a child seat fitted  
forward facing.  
To do this, move the front seat forwards  
and, if necessary, move its backrest into the  
upright position.
