FULLY automatic climate control air-conditioning is standard across the A4 range and has two "zones" to allow both the front passenger and driver to adjust the temperature according to their personal requirements. Operation of the climate controls is an all-button affair - plus and minus buttons are given for temperature and fan speed, with separate buttons for air distribution, economy mode, recirculation and front and rear demist. Two large vents are positioned on the centre dash, with an additional vent at either end of the dash. There are no vents dedicated for rear-seat passengers.
