| ACC | The adaptive cruise control (ACC) is an advanced cruise control system which maintains the correct distance to the vehicle in front within certain system limits. |
| ASR | The traction control system (ASR) prevents the wheels from spinning under acceleration.

| CAN | A controller area network (CAN) is a serial data bus with a transmission rate of up to 1,000,000 bit/s. |
| ESP | The electronic stabilisation program (ESP) enhances the control over the vehicle in critical handling situations. |
| CCS | The cruise control system (CCS) is an electronic aid for controlling the driving speed. |
| EBC | The engine braking control (EBC) prevents the driven wheels from slipping on a smooth road surface if the driver releases the accelerator pedal or changes down a gear too quickly. |
| MMI | The Multi Media Interface (MMI) is an integrated operating concept used by Audi for easy, logical and intuitive operation of on-board car systems and infotainment components. |
| RADAR | Radar is an acronym for radio detection and ranging and is the designation for various detection and direction finder systems which use electromagnetic waves in the radio frequency range. |
