WARNING
While the vehicle is moving, children must always be protected with a restraint system which is suited to their age, height and weight. Please refer to the chapter “Child seat categories”.
• Never install a rearward-facing child safety seat on the front passenger's seat unless the front passenger's airbag has been deactivated. This could result in potentially fatal injuries. If you have no alternative but to let a child travel on the front passenger's seat, the front passenger's airbag must be deactivated beforehand.
Please refer to the chapter “Deactivating airbags”.
• Note the important information and warnings concerning the use of child safety seats found in the chapter “Important safety notes when using child safety seats” and in the installation instructions provided by the manufacturer of the child safety seat.
