uuChild Safety uSafety of Larger Children
Safe DrivingIf a lap/shoulder seat belt cannot be used
properly, position the child in a booster seat in
the rear seat. For the child’s safety, check that
the child meets the booster seat
manufacturer’s recommendations.
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:
• Make sure you read and fully understand the instructions and safety information
in this manual.
• Move the front passenger seat as far back as possible.
• Have the child sit upright and well back in the seat.
• Check that the seat belt is properly positi oned so that the child is secure in the
seat.
■Monitoring child passengers
We strongly recommend that you keep an eye on child passengers. Even older, more
mature children sometimes need to be remi nded to fasten their seat belts and sit up
properly.
■Booster Seats1 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. 6 years or 60
lbs). Be sure to check current laws in the state or
province, or territory where you intend to drive.
