Where is the external circulation button on the Hyundai ix35?
1 Answers
The external circulation button is a single-point bidirectional switch, whose main function is to replenish fresh air into the vehicle. The external circulation button uses the heater fan to draw fresh air from outside the vehicle into the interior, with the fan's air source coming from outside. Even when the fan is not turned on, fresh air will still be drawn into the vehicle while driving. Here is additional information: Correct usage of internal and external circulation: Turn on internal circulation during traffic jams and external circulation on highways. During long highway drives, the air inside the vehicle can become stale, so the external circulation function can be used to draw in fresh air. The primary purpose of turning on the air conditioning is to lower the temperature inside the vehicle, so external circulation should not be activated; however, external circulation can be turned on periodically to refresh the air.
