Here's another green tip from Richmond Auto Mall on how you can do your part for the environment.
Stay cool the cool way by going green. When its warm outside use the vents and windows before turning on the A/C. Using your air conditioner increases fuel consumption, nitrous oxide emissions in some vehicles, and involves environmentally damaging fluids.
We all know shades are cool so try parking in the shade or using a windshield shade in the heat.
Going green has never been easier!
