Your vehicle has a rear seat where children can be properly restrained. If you ever have to carry a group of children, and a child must ride in front:
Monitoring child passengers
We strongly recommend that you keep an eye on child passengers. Even older, more mature children sometimes need to be reminded to fasten their seat belts and sit up properly.
Booster Seats
When installing a booster seat, make sure to read the instructions that came with it, and install the seat accordingly.
There are high- and low-type booster seats. Choose a booster seat that allows the child to wear the seat belt correctly.
Some U.S. states, and Canadian provinces and territories require children to use a booster seat until they reach a given age or weight (e.g. six years or 60 lbs). Be sure to check current laws in the state or province, or territory where you intend to drive.
