Make sure your child's safety seat and safety belt buckles aren't too hot before securing your child in a safety restraint system, especially when your car has been parked in the heat.
Never leave your child unattended in a vehicle, even with the windows down.
Teach children not to play in, on or around cars.
Always lock car doors and trunks even at home and keep keys out of children's reach.
Always make sure all children have left the car when you reach your destination. Don't leave sleeping infants in the car ever!
