How can I install the Maxi-Cosi Rubi sturdy in my car?
Please follow the red marking on the product, then tension the car belt before locking the top central belt lock. Read the user manual of the Maxi-Cosi Rubi carefully prior to installation to ensure correct fit in your car and see the installation film available o the product page of this website
When can my child switch from an infant seat to the Maxi-Cosi Rubi?
Make sure your baby’s head is generously protected by the (top of the) car seat. Your baby has outgrown his baby car seat when the top of his ears extend past the top of the car seat shell. Do not switch to the Maxi-Cosi Rubi until this time and keep you baby rearward facing for as long as possible in order to protect the fragile neck and head. Note: it is not a problem if the child’s legs extend beyond the edge of the seat.
What should I do if my child opens the buckle on his or her harness belt?
In this case, we recommend, as do all international safety experts, that you stop immediately in a safe place, fasten the buckle once more and tell the child not to open it and the reason for this. It is always a possibility that an inventive, handy or strong child will open the buckle. If the force required to open the buckle were to be considerably increased to make it impossible for the child to open it himself, this would be contrary to the legal safety standards. The position of the buckle, the colour of the button, and the operating or opening force are all laid down in European standards. In the case of an accident, someone providing assistance without any knowledge of car seats must be able to see immediately how to release the child from a car seat in an emergency.
The belts are not the same length. Why is this?
Uneven belts may be caused by the incorrect guiding of the harness system. Check at the back of the car seat that the belts are not twisted and that the pull belt (that runs forward at the bottom of the shell) is in the middle of the system. Also check that the belt can move easily to and fro through the shoulder openings. For smooth movement, the belt buckle should be flapped forward completely. This belt buckle operates by releasing the belt tensioner. If the problem continues after you have checked this, consult your retailer.
Why do Maxi Cosi group 1 car seats have a 5-point safety harness?

All group 1 car seats of Maxi-Cosi have 5 point safety harness with one-pull adjustment. This harness distributes the forces of an impact best over the strong bones of the child and into the seat. Additionally, the 5 point harness allows perfect adjustment of the child and keep him secured in the safest position in the seat.

What is the right position for the headrest of my child car seat?
The child's head has to be totally protected and should not exceed the headrest.
What is the right position/height for the safety harness?

The harness straps should be placed at the level of the shoulders, not coming from above nor below. The headrest should be adjusted in consequence, keeping the harness at the level of the shoulders.

Do I have to adjust the safety harness each time I place my child in the car seat?
Yes. Each time you install your child in the car seat you should fasten the safety harness. This is because the child can wear different clothing. If the harness is correctly tight, you should be able to pass only 1 finger between your child's body and the harness strap.
