Child Restraint

Caution: A child in a rear-facing child restraint can be seriously injured if the right-front passenger's air bag inflates. This is because the back of a rear-facing child restraint would be very close to the inflating air bag. It is always better to secure a child restraint in the rear seat. If a forward-facing child seat is suitable for your child, ALWAYS move the front passenger seat as far back as it will go and then install the child restraint. Be sure the child restraint position does not conflict with any additional requirements provided by the manufacturer. For more information, refer to the vehicle owner's manual and the instructions that came with the child restraint.

The child seat should be installed and secured according to the manufacturer's directions. If the child seat has a top strap it will need to be anchored. Refer to Child Seat Restraint System Belt Kit . Passengers should not be allowed to sit at locations where the seat belts are being used to secure the child seat.
