High safety standards
With a thoroughly optimised body design and
comprehensive safety equipment, the new
Audi A4 is able to comply with all current valid
safety standards, throughout the world.
Crash sensors for the front airbags integrated
directly into the bumper bar, improve occu-
pant protection.
Finely-tuned aerodynamics
Despite the greater frontal area and the cool-
ing air current for the air conditioner (stand-
ard), it was possible to improve the C
D

value
by 5 %, in comparison to its predecessor,
to 0.28.
A special feature is the so-called aero-floor,
which provides for optimal airflow on the
underside of the vehicle.
Communication centre on wheels
With regard to infotainment, the new
Audi A4 leaves nothing to be desired.
4 different audio systems, 2 differently config-
ured Navigation systems and a car phone
with voice operation are on offer.
Electronic stability programme (ESP)
including brake assistant
For the latest ESP generation, the hydraulic
brake assistant is an integral part of the
standard equipment.
It is intended to assist the driver by automati-
cally increasing the brake pressure during
emergency braking.

The system comprises driver/passenger air-
bags, front side airbags, optional rear side
airbags, SIDEGUARDS
®

, three point front seat
belts with ball tensioners and belt force limit-
ers, three point rear outer seat belts, centre
lap belt (for fixed rear seat bench), Isofix pre-
paration in rear of vehicle, and a total of 6
non-central accelerometers:
– 2 front impact crash sensors
– 2 driver/passenger side airbag crash sen-
sors, (in the B-pillar for side impact)
– 2 driver/passenger rear side airbag crash
sensors, (on the C-pillar for side impact) To complement the comprehensive body
modifications, occupant protection has been
improved through the further development of
the familiar 8.4 airbag system.
The new generation bears the designa-
tion 8.4 E, where the E stands for
"extended".
The position of the sensors is selected so that
they are installed as near as possible to the
outer structure of the vehicle.
This enables quicker deceleration detection in
the event of an impact.The external sensors deliver digitised acceler-
ation data to the airbag control unit, which is
then evaluated in the control unit and which
triggers the relevant restraint system compo-
nents.

Crash signal processing
There are two separate crash signal outputs:
One crash signal is output via the conven-
tional wiring and triggers the following func-
tions:
– Transmitting an emergency call via the
control unit for telephone/telematics J526
(optional)
– unlocking the vehicle,
– Switch on interior light
(switch must be set to door contact),
– switching on hazard warning lights via the
central convenience electronics J393.
The auxiliary heater J162 (optional) is
switched off by the central convenience
electronics J393 via a CAN convenience
message.
The second crash signal output functions via
the convenience CAN bus, which switches off
the engine fuel supply via the engine control
unit J220.

CAN data bus
The Audi A4 is equipped with a widely
extended CAN data bus system.
Due to the ever increasing number of control
units installed in the vehicle and the associ-
ated requirement for data exchange, the
importance of the CAN data bus system
increases significantly.For communication between the
installed control units and the diagnos-
tic tester, two diagnosis wires (K and L)
are available.
The newly developed adapter VAS 6017 ena-
bles communication with all control units.

Navigation IV and Navigation Plus-D
The new Navigation System IV and Navigation
System Plus-D are equipped with the dynamic
routing system.
The following traffic hold-ups are taken into
account during route planning:
– closed roads
– tailbacks and
– slow-moving traffic.
The system’s sources of information are the
traffic information from the radio stations via
the Travel Message Channel and from the
telematics
®

(optional) via the telephone
connection.
Once it is switched on, the navigation system
takes account of the traffic messages within a
radius of approx. 50 km around the vehicle.
If the route planning is activated, any hold-
ups are taken into consideration.
New hold-ups which arise are immediately
accounted for in the routing and the driver is
re-routed.
Data transfer of the traffic data is by
– Travel Message Channel data from the
radio
– Telephone data from the telematics control
unit J526
to the navigation system via the data bus
information system.

Menu

Within the menu structure of the navigation
system, the driver is able to
– switch the dynamic routing on and off,
– select the source of traffic information,
– manually exclude route sections from the
route planning.
For further information, please refer to the
operating instructions.
Travel Message Channel (TMC)
The TMC is a component of the Radio Data
System (RDS), which is transmitted by the
radio stations.
The information in the TMC includes the loca-
tion, type and duration of traffic hold-ups
reported by the police, automobile associa-
tions and government authorities in a coded
form standard throughout Europe.
The TMC data is not currently transmitted by
all radio stations.
This requires the use of a second tuner in the
radio or in the interface of the Navigation
System Plus.
As only the symphony II radio is equipped
with a second tuner, the use of TMC data for
dynamic routing is only possible with this
version.
Dynamic routing in conjunction with the
chorus II and concert II radios is only possible
by means of the traffic messages via tele-
phone with telematics

The navigation system diagnostics is interro-
gated via the L-wire.

Multi-communication bar (MCB)
The Audi A4 Saloon features the multi-com-
munication bar in the top part of the rear win-
dow for the first time.
The
– aerial module,
– aerial for navigation system (GPS),+
– and aerial for telephone (GSM)
are fitted in the MCB.
The
– aerial diversity,
– aerial amplifier for the four radio aerials
(FM1-4, AM),
– 4 aerial amplifiers for the TV aerials 1-4,
– aerial for radio remote control, central lock-
ing (RCL),
– and the aerial for the telestart function (TS)
of the auxiliary heating
are integrated in the aerial module.
The aerial conductor is located in the rear
window. The electrical connection between
the aerial amplifier and the conductor on the
rear window is made by means of spring
contacts.
Both the GPS and the GSM aerials are also
fitted in the top edge of the rear window, but
these are not connected by means of conduc-
tors in the rear window.
Thanks to this compact arrangement, no
aerials are visible from outside.
The emergency aerial for the telematics is
located at the rear bumper.
