LOL, I guess I would not make a good eye witness. In my head I pictured 4 blue lights but you are correct, there are only 3.
Tonight in NJ Carbon Monoxide: Not from a car in this case but 400 people in the US every year. Sucks the O2 out of your blood so even if you get to fresh air, normal respiration may not be enough. Carbon monoxide leak kills teen, sickens 41 others in New Jersey — RT US News
I remember back in the Prius early days remote starters were a no no. A remote starter, are you crazy, do you know what that will do to your gas mileage, you can't be a real tree hugger. Just having fun. Lol
I work at a Poison Control Center. We have several CO poisonings each year. Most are from home appliances or generators. All combustible engines produce carbon monoxide, including diesel engines. In a large enough exposure, it does cause effects. Please do not think that it is "safe" with a newer vehicle because of the emission controls/catalytic converter. From Iowa State UniversityDepartment of Agricultural and Biosystems Engineering: How can CO poisoning occur if the engine has a catalytic converter? Exhaust gas that leaks out before the catalytic converter has high CO concentrations. Out-of-tune or misfiring engines produce elevated concentrations of carbon monoxide and unburned fuel that can destroy the catalytic converter. During cold starts the catalytic converter is ineffective. And if there is insufficient oxygen (caused by operation in a closed building or with a defective oxygen system), there will not be enough oxygen for oxidizing the CO to CO2. Concerning CO, from Poisondex, a product from Micromedex: A) SOURCES: Odorless, colorless gas produced by the incomplete combustion of any carbon containing substance. Common sources include household fires, home furnaces, stoves and water heaters, and vehicle exhaust. Another potential source is methylene chloride (often used as a paint stripper or degreaser) that is absorbed through inhalation, ingestion, or dermal contact and is subsequently metabolized by the liver to carbon monoxide. B) PHARMACOLOGY: Binds to hemoglobin with an affinity approximately 250 times greater than that of oxygen. C) TOXICOLOGY: Impairs oxygen delivery, producing cellular hypoxia and ischemia. D) EPIDEMIOLOGY: Common poisoning; one of the leading toxicologic causes of death.
I use the pre- condition (AC button on fob) every morning and start feeling heat immediately upon drive off. However when shutting the car off for the night, you must leave it in your desired preset temp for morning. This should be about a half hour before drive off. Works in Ca, but perhaps not in Buffalo.
