   • Make sure all other windows are shut.
   • Turn the fan on your heating or cooling system to its highest speed and select the control setting that will force outside air into your vehicle. See Climate Control System .
   • If you have air outlets on or under the instrument panel, open them all the way. See Engine Exhaust .
