Outlet Adjustment Climate Controls Personalization If your vehicle is equipped with the Driver Information Center (DIC), you can store and recall the climate control settings for temperature, air delivery mode and fan speed for two different drivers. The personal choice settings recalled are determined by the transmitter used to enter the vehicle. After the button with the unlock symbol on a remote keyless entry transmitter is pressed, the climate control will adjust to the last settings of the identified driver. The settings can also be changed by pressing one of the memory buttons (1 or 2) located on the driver's door. When adjustments are made, the new settings are automatically saved for the driver. Your vehicle may have rear seat outlets that can be used to adjust the airflow toward either seating area, the floor or upward. Move the control in the center of each outlet in any direction to direct airflow. 3-34
