Main Menu Table Of Contents 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. When the indicator in the dual button is on, the driver's side and passenger's side temperature can be controlled independently (see page 177). When the indicator in the rear button is on, the temperature of the rear passenger compartment can be controlled independently (see page 177). On models with navigation system Dual 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 sun light 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. You can set the temperatures for the driver's side and the passenger's side separately when this button is pressed (indicator is on). When the indicator in the DUAL button is off, the temperatures for both sides are synchronized to the driver's side set temperature. When defrost mode is selected, dual mode operation is canceled. 172 2009 MDX
