Safety
5It is recommended that children travel
on the rear seats of the vehicle:
–

"rearward facing" up to the age of 3,
–

"forward facing" over the age of 3.
Make sure that the seat belt is correctly
positioned and tightened.
For child seats with a support leg, ensure that
the support leg is in firm and steady contact
with the floor.
An incorrectly installed child seat in a vehicle compromises the child's safety 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 harness 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 vehicle seat. If
the passenger seat is adjustable, move it
forwards if necessary.
Remove the head restraint before
installing a child seat with a backrest on 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 once
the child seat has been 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.
Use a booster seat with a backrest, equipped
with a belt guide at shoulder level.
Additional protections
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 sun's rays,
fit side blinds on the rear windows.
As a safety measure, do not leave:
–

A

child alone and unsupervised inside 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.
Child seat at the rear
Forward-facing or rearward-facing



► Move the vehicle's front seat forward and
straighten the backrest so that the legs of the
child in the forward-facing or rearward-facing
child seat itself do not touch the vehicle's front
seat.
►

Check that the backrest of the forward-facing
child seat is as close as possible to the backrest
of the vehicle's rear seat, and ideally in contact
with it.
Centre rear seat
A child seat with a support leg must never be
installed on the centre rear passenger seat .
