Nissan ARIYA 2023 Owners Manual
5.3.2.2. Large children
Never allow children to stand or kneel on any seats.
Never allow children in the cargo areas while the vehicle is moving. A child could be seriously injured in an accident or sudden stop.
Children who are too large for a child restraint system should be seated and restrained by the seat belts that are provided.
If the child's seating position has a shoulder belt that fits close to the face or neck, the use of a booster seat (commercially available) may help overcome this. The booster seat should raise the child so that the shoulder belt is properly positioned across the top, middle portion of the shoulder and the lap belt is low on the hips. The booster seat should also fit the vehicle seat. Once the child has grown so that the shoulder belt is no longer on or near the face or neck of the child, use the shoulder belt without the booster seat. In addition, there are many types of child restraint systems available for larger children that should be used for maximum protection.
