Off Mode

Selecting the OFF mode will cancel all blower, A/C and recirculation requests. When the vehicle is moving, air flowing over the vehicle increases the air pressure just ahead of the windshield. This forces air into the HVAC air inlet and out through any desired mode setting. The HVAC air temperature can be adjusted, but since the A/C compressor is not running, the incoming air may be warmed but not cooled.
