I cannot fit the Maxi Cosi Priori car seat properly in my car. Am I doing something wrong?
It does happen that in spite of the instructions on the stickers and in the user instructions people still place the diagonal or shoulder belt in the two red belt clamps. This will not work. Loosen the Maxi Cosi Priori and install it again and this time exactly according to the user instructions, with the shoulder belt only attached in a red belt clamp on one side where the belt goes up to the roll-up mechanism. Close this clamp and then pull the shoulder belt tight. Check the attachment. Although there is still always a small amount of movement, the seat should now be fixed firmly in the car.
