In addition to the standard specification, numerous optional extras provide scope for numerous different versions so that each S4 can be designed individually and in keeping with the customer's personal taste. Here are just a few examples:
Audio systems, with 6 CD changer in the glove box and BOSE sound system as an option, provide a musical contrast to the sporty sound of the engine and, depending on features, traffic information using RDS technology.
Audi telematics provides an additional advantage in terms of information. The latest traffic information can be called up in accordance with the driver's personal needs for a specific region or route and, if a navigation system is fitted, converted into graphic warnings about traffic hold-ups. Audi telematics also includes a service and emergency call function.
Seats and trims can be ordered as an option in a combination of Alcantara/leather or in Silk Nappa leather.
The basic car phone, radio and navigation functions can be operated at the optional 4-spoke multifunction steering wheel - which can also be supplied as a heated version if required. Voice control for operating the most important navigation, audio and car phone functions provides additional convenience and even greater operating reliability.
Insulating glass and the solar sunroof for supplying power to the car's ventilation system when the ignition is turned off ensure a particularly high standard of comfort in high outside temperatures. At the same time, a coolbox in the glove compartment keeps refreshing drinks at a pleasant temperature.
