Never, never, never leave children, disabled or elderly adults, or pets in parked, unattended vehicles! Studies have shown that the temperature inside a parked vehicle can rapidly rise to dangerous levels for people and pets. Leaving the windows slightly open does not significantly decrease the heating rate. The effects can be more severe on children because their bodies have not developed the ability to efficiently regulate internal temperature.
