Using Your Vehicle to Stay Warm
If you are going to use your vehicle to charge your phone or heat up, make sure you are in a well ventilated area.
Do NOT run your vehicle in your garage or any other enclosed spaces.
If you are in a parking lot where others are doing the same, use the recirculate function like you would during traffic.
Make sure your tailpipe is not being obstructed. This could cause the emissions to be redirected.
It's always so heartbreaking to hear stories where people have passed away due to carbon monoxide poisoning in their vehicle as a result of trying to stay warm.
