Children at the rear
At rear seating positions, always leave 
sufficient space between the front seat 
and:
- 
t
 he "rear ward facing" child seat,
-
 
t
 he child's feet for a   child seat fitted 
"forward facing".
To do this, move the front seat for wards 
and, if necessary, straighten its backrest.
For optimal installation of the "forward 
facing" child seat, verify that its backrest is 
as close as possible to the backrest of the 
vehicle seat, if possible in contact with it.
A child seat with ISOFIX or i-Size 
mountings must never be installed on the 
centre rear passenger seat.
Children at the front
Deactivate the front passenger airbag 
when a "rear ward facing" child seat is 
installed on the front passenger seat.
Otherwise, the child would risk being 
seriously injured or killed if the airbag 
were deployed. 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.
We recommend using a
  booster seat with 
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 rays 
of the sun, fit side blinds on the rear 
windows.
As a
  safety precaution, do not leave:
-
 
a c
 hild or children alone and 
unattended 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.Child seat at the front
When a child seat is installed on the 
f ront passenger seat , adjust this seat 
to the highest position , in the rearmost 
longitudinal position , with the backrest 
straightened .
"Rearward facing "
The front passenger airbag must be 
deactivated. Otherwise, the child risks 
being seriously injured or killed if the 
airbag is deployed .
"Forward facing "
You must leave the front passenger airbag 
active.
