The left button with the fan symbol regulates the fan speed. The right button is used to change the direction of airflow (upper, bi-level or floor) to the rear seat area. To turn the rear climate controls on or off, press the middle button. The rear control will only turn on if the front is on and is not in defrost mode.

Ventilation System

For mild outside temperatures when little heating or cooling is needed, use the panel outlet setting to direct outside air through your vehicle. Air will flow through the instrument panel outlets.

Your vehicle's flow-through ventilation system supplies outside air into the vehicle when it's moving. When the vehicle is not moving, you can get outside air to flow through by selecting any air delivery mode and any fan speed.

Your vehicle has air outlets that allow you to adjust the direction and amount of airflow inside the vehicle. Move the control in the center of each outlet side-to-side to direct the air from the outlet. Use the thumbwheel under the outlet to close the louvers. For the most efficient airflow and temperature control, keep the louvers in the fully opened position.
