Audi HD Matrix LED technology provides precise and higher-resolution illumination of the road whilst reducing the disk of dazzling other road users. The Coming and Leaving Home function displays unique animations within the front and rear lights when the car is locked and unlocked. Using information obtained from the vehicle's sensors, camera and MMI Navigation, the HD Matrix LED headlights identify the appropriate lighting required and automatically dip or turn off individual lighting diodes, creating corridors of light on either side of the vehicle or the object in front of it.
