Chapter 3 Passenger Protection; Safety System - Audi A6´05 323 Service

Passenger protection

Safety system

A top-level safety system: The performance target is
to increase the existing high safety level of the
current Audi fleet.
The compliance with current laws and the
completion User tests, in which the new
Audi A6´05 was to gain a top position in the rating
scheme, were only a part of the extensive safety
requirements. In many cases, additional Audi
in-house requirements increase the requirements
which have to be met by the development team.
Particular attention was paid to a high protection
potential in the event of an accident and the
compatibility. Audis's policy of designing vehicles
with high safety specifications is supplemented
by scientifically gained knowledge of the
actual accident and its effects.
For this, the AARU (Audi Accident Research Unit*)
examines crashes involving relatively new
Audi vehicles.
The development team's task is to analyse and
reconstruct accidents and to draw up potential
improvements.
In addition to this, the AARU evaluates the relevant
accident databases.
Note
Observe the respective safety instructions
in the repair guide before carrying out
any work on the airbag system!

The safety system in the Audi A6´05 comprises the
following familiar components:
– Airbag control unit
– Driver and front passenger airbags, two-stage
– Front side airbags
– Sideguards (head airbags)
– Sensors for side crash detection
– Front belt tensioners
The Audi A6´05 has the following new components:
– Crash sensors for the front airbag, the so-called
upfront sensors for frontal crash detection
– Battery cut-off relay
– Sensors for side crash detection in the doors
– Switches in the front belt locks
– Seat occupied recognition in the front passenger
seat
The vehicle can be equipped with side airbags at the
rear and a key switch for deactivating the front
passenger airbag with a corresponding warning
lamp (optional).
The safety system in the Audi A6´05 is rounded off
by the active head restraints in the front seats.
The A6´05 thus constitutes a successful example of
an overall vehicle development aimed at protecting
the passengers.
Due to the different demands and legal
provisions which car makers are subject to in
the different markets, the equipment can vary for
the US American market in particular.
