Solar Angle

This screen graphically displays the sun's position as determined by GPS. The HVAC system uses the navigation systems sun's angle, along with the sunlight sensor to control the driver/passenger A/C airflow. The heat that the climate control unit removes varies, depending on the angle of the sun entering the vehicle. This screen is for factory use only, and should not be adjusted.

• The screen shows a circular diagram of the sky oriented in the direction that the vehicle is pointing. During daylight hours a red dot is shown, representing the direction and elevation of the sun. The outer circle represents the horizon (0 degrees elevation). The middle circle is 30 degrees, the center circle is 60 degrees, and the very center is directly overhead (90 degrees).
• The manual tuning button should always be OFF.
• The Angle is the angle that the sun (shown with red dot) is above the horizon.
• The vehicle value represents the angle, clockwise from North, to the direction that the vehicle position (VP) icon is pointing (always points straight up).
• The direction value is the angle, measured clockwise from the VP (straight up) to the suns position.
• The reliability ranges from 1 to 3, and represents the accuracy of the Vehicle Position relative to the sun.
