Vent

When the driver presses the VENT button, the VENT LED illuminates, the air inlet actuator is set to deliver outside air and the system requests that the A/C compressor be turned OFF.

The VENT button has no effect on the system when the FRONT DEFROST mode is selected.

When the Vent button is pressed with the system OFF, the blower and mode are set to automatic control.
