General points relating to child seats
Although one of CITROËN main criteria when designing your vehicle, the safety of your children
also depends on you.
For maximum safety, please observe the
following recommendations:
- in accordance with European regulations,
all children under the age of 12 or less
than one and a half metres tall must
travel in approved child seats suited to
their weight , on seats fitted with a seat
belt or ISOFIX mountings * ,
- statistically, the safest seats in your
vehicle for carrying children are the
rear seats,
- a child weighing less than 9 kg must
travel in the "rearwards-facing"
position both in the front and in the
rear.
CITROËN recommends that children
should travel on the rear seats of your
vehicle:
- "rearward-facing" up to the age
of 3,
- "forward-facing" over the age of 3.
* The rules for carrying children are specific to
each country. Refer to the legislation in force
in your country.
