Climate Control System When you set the temperature to its lower limit ( ) or its upper limit ( ), the system runs at full cooling or heating only. It does not regulate the interior temperature. When you press a fan control button, the fan is taken out of AUTO mode. On vehicles with navigation system SYNC Button In the Auto mode, the vehicle's interior temperature is independently regulated for the driver, front passenger, and rear passengers according to each adjusted temperature. The system also regulates each temperature based on the information of the sunlight sensor and the sun's position which is updated automatically by the navigation's global positioning system (GPS). For example, if the driver's side of the vehicle is getting too much sun, the system will adjust to a lower temperature. When you press this button, the indicator in the button comes on, and the passenger's side temperature and the rear passenger compartment is synchronized to the driver's side set temperature. Changing the passenger's side temperature or pressing any control button for the rear passenger compartment makes the indicator go off, and takes the system out of SYNC mode. Features 2011 Odyssey 227
