E::::I Alternator/vehicle battery
• Electrical system: malfunction! Battery is
not being charged
There is a malfunction in the alternator or the ve­
hicle electrical system .
Drive to an authorized Audi dealer or authorized
Audi Service Facility immediately. Because the ve­
hicle battery is discharging, turn off all unneces­
sary electrical equipment such as the radio. See
an authori zed Audi dealer or authori zed Audi
Service Facility if the battery charge level is too
low .
r•j low battery: Battery will be charged while
driving
The starting ability may be impaired.
If this message turns off after a little while, the
vehicle battery charged enough while driving.
If the message does not turn off, have an author­
ized Audi dealer or authorized Audi Service Facili­
ty repair the malfunction .
~ Engine stop while driving
• Engine stopped: No power steering and
brake support.
There is a malfunction in the engine or in the fuel
supply system.
More force is needed to steer and brake the mov­
ing vehicle when the engine is stopped . If the ve­
hicle is rolling, try to bring it to a stop off to the
side from moving traffic. See an authorized Audi
dealer or authorized Audi Service Facility for as­
sistance.
_& WARNING
If the engine stops while driving, you will
need to use more force to brake the vehicle.
This increases the risk of an accident. There
will still be power steering if the ignition is

Airbag system
must be performed by qualified workshops
only. Make sure that any airbag service ac­
tion is entered in your Audi Warranty
&
Maintenance booklet under AIRBAG RE·
PLACEMENT RECORD .
-For safety reasons in severe accidents, the
alternator and starter are separated from
the vehicle battery with a pyrotechn ic circuit
interrupter.
- Work on the pyrotechnic circuit interrupt­
er must only be performed by a qualified
technicians who have the experience, in­
formation and special tools necessary to
perform the work safely.
- If the vehicle or the circuit interrupter is
scrapped, all applicable safety precautions
must be followed .
@ For the sake of the environment
Undeployed airbag modules and pretension­
ers might be classified as Perchlorate Materi­
al
-special handling may apply , see
www .dtsc.ca.gov/hazardouswaste/perchlo ­
rate . When the vehicle or parts of the re­
straint system including airbag modules and
safety belts w ith pretensioners are scrapped,
all applicable laws and regulations must be
observed . Your authorized Audi dealer is fa­
miliar with these requirements and we recom­
mend that you have your dealer perform this
service for you.
Other things that can affect Advanced
Airbag performance
Changing the vehicle's suspension system can
change the way that the Advanced Airbag System
performs in a crash. For example, using tire-rim
comb inations not approved by Audi, lower ing the
vehicle, chang ing the stiffness of the suspension,
including the springs, suspension struts , shock
absorb ers etc . can change the forces that are
measured by the airbag sensors and sent to the
electronic control unit . Some suspension changes
can, for example, increase the force levels meas­
ured by the sensors and make the airbag system
deploy in crashes in which it would not deploy if
the changes had not been made. Other kinds of
162
changes may reduce the force levels measured by
the sensors and prevent the airbag from deploy­
i ng when it should .
& WARNING
Changing the vehicle's suspension including
use of unapproved tire-rim combinations can
change Advanced Airbag performance and in­
crease the risk of serious personal injury in a
crash .
- Never install suspension components that do not have the same performance charac­
teristics as the components origina lly instal­
led on your vehicle.
- Never use tire-rim combinations that have
not been approved by Aud i.
Knee airbags
Description of knee airbags
Applies to: vehicles with knee airbags

the driver's and passenger's knees and upper and lower thigh areas and supplements the protec­
tion prov ided by the safety belts .
If the front airbags deploy, the knee airbags also
deploy in frontal coll is ions when the deployment

Checking and Filling
belt, alternator and radiator fan) and from
the high-voltage ignition system.
- Do not under any circumstances give gas in­
advertently (for example, by hand from the
engine compartment) if the vehicle is sta­
tionary but the engine is running and a gear
is engaged. Otherwise, the vehicle will start
to move immediately and this could result
in an accident.
- Pay attention to the following warnings list­
ed when work on the fuel system or on the
electrical equipment is required.
- Do not smoke.
- Never work near open flames.
- Always have a working fire extinguisher
nearby.
- All work on the battery or electrical system
in your vehicle can result in injuries, chemi­
cal burns, accidents or burns. Because of
this, all work must be performed
only by an
authorized Audi dealer or authorized Audi
Service Facility.
- To reduce the risk of electric shock and in­
jury, never touch the following components when the engine is running or is being start­
ed:
- Ignition cable
- Other components in the electronic high-
voltage ignition system
- If you must check or perform work on the
engine while it is running:
- Set the parking brake and place the selec­ tor lever in the P (park) position first.
- Always proceed with extreme caution so that clothing, jewelry or long hair do not
become caught in the radiator fan, fan
belt or other moving components or do
not come into contact with hot compo­
nents. Tie back long hair before beginning
work and do not wear clothing that can
hang down into the engine.
- Limit your exposure to exhaust and chemi­
cals to as short a time as
possible~ &..
