Never leave your child in an unattended car, even with the windows down. Always make sure that all child passengers have left the car. Make sure you check the temperature of the car seat surface and safety belt buckles before restraining your children in the car. Use a light covering to shade the seat of your parked car. Consider using windshield shades in front and back windows.
Car trunks can be especially hazardous.
Kids get in but can't always get out. In very hot weather, heat stroke may result and could lead to permanent disability or even death in a matter of minutes. Keep the trunk of your car locked at all times, especially when parked in the driveway or near the home. Keep the rear fold-down seats closed to help prevent kids from getting into the trunk from inside the car. Put car keys out of children's reach and sight.
