Air Quality Tips
Check your air quality before you go out. Schedule outdoor activities and yard work in the mornings, particularly if AQI is forecasted to reach orange or red levels. You may also check the National Weather Service Air Quality Forecast Guidance.
Don't top off! Refuel your vehicle in the early morning or evening.
April is National Car Care Month. Car care equals clean air. Visit Reducing Ozone for more information on simple everyday steps you can take to help reduce harmful vehicle emissions.
