The system also regulates each temperature based on the information of the sun light sensor and the sun position which is updated automatically by the navigation's global positioning system (GPS). For example, if the driver's side of the vehicle getting too much sun, the system will adjust to a lower temperature. When you turn the ignition switch to the ON (II) position, the temperature of the rear passenger compartment is synchronized to the driver's side set temperature. You will see SYNC on the system display of the rear control panel. Changing the temperature of the rear passenger compartment takes the system out of synchronized mode. This causes the word SYNC in the display to go out and displays the rear temperature in the front display. When you turn the ignition switch to the ON (II) position and see LOCK on the system display of the front and rear control panels, the temperature of the rear passenger compartment is not synchronized to the driver's side set temperature.
