CLIMATE control air-conditioning is standard on the B4 and it's the same system as used in Liberty RX and Heritage models, so the controls are clearly marked and easy to use. There is a rotary dial for temperature adjustment with a range of 18 to 32 degrees (moving in 0.5 degree intervals), while all other functions are controlled via buttons surrounding the LCD display, including an outside temperature indicator. A cabin air temperature sensor is located on the right-hand side of the control panel, sending information to the auto function to control the four-speed fan and maintain the set temperature. No air vents are provided for rear seat occupants although ducts channel air to the back of the cabin from under the front seats.
