Child Seat Restraint System

Caution: A child in a rear-facing child restraint can be seriously injured if the right-front passengers air bag inflates. This is because the back of a rear-facing child restraint would be very close to the inflating air bag. NEVER use a rear-facing child restraint in this vehicle. If a forward-facing child restraint 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 owners manual and the instruction 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. This applies for seats designed with a top strap provision and for vehicles sold in Canada. Refer to Child Restraint Tether Anchor Replacement .

Rear-Facing infant seats must only be used the REAR seat. This type of restraint faces the rear so that the infants head, neck and body can have the support they need in a frontal crash. Rear-facing restraints are designed for infants up to about 20 lbs. (9 kg) and about one year of age.

Some vehicles are equipped with rear-facing seats. Do not use a child seat on a rear-facing seat.

Do not allow passengers to sit at locations where the seat belts are being used in order to secure the child seat.
