The Audi A3 '04 features a range of details that were previously exclusive to higher-end cars, such as pre-fitted components for mobile phone installation with voice control. This allows drivers to keep both hands on the wheel. The A3 '04 also provides an advanced sound system with a center loudspeaker for enhanced acoustics and natural sound reproduction. The standard of control unit networking has been elevated to that of mid-range vehicles, with more than twice the number of interconnected control units compared to the previous model. This enables a wide range of high-quality functions in the compact class.

Safety systems

The safety system in the Audi A3 ’04 has been revised and adapted accordingly to meet with current and future demands in terms of occupant safety.

The system essentially consists of the familar components: Airbag control unit, driver's and front passenger's airbag, front side airbags, front belt tensioners, sideguards (head airbags) and side impact recognition sensors.

New features are the external front airbag crash sensors (so-called upfront sensors for detection of head-on collisions) and battery deactivation in the event of a crash on vehicle models with the battery fitted in the luggage compartment.

Vehicles can optionally be equipped with a key switch for front passenger's airbag deactivation and the corresponding warning lamp.

The Audi A3 ’04 safety system is rounded off by the active head restraints in the front seats.

For the first time use is made in the Audi A3 `04 of airbag modules which are not subject to any replacement intervals.

Always heed the corresponding safety regulations outlined in the Workshop Manuals before working on the airbag system.
