156 Airbag system
There are some important things you have to
know to make sure that the effectiveness of
the system will not be impaired and that dis­
carded components do not cause injury or pol ­
lute the environment.
A WARNING
Improper care, servicing and repair proce­
dures can increase the risk of personal in­
jury and death by preventing an airbag
from deploying when needed or deploying an airbag unexpectedly:
- Never cover, obstruct, or change the
steering wheel horn pad or airbag cover
or the instrument panel or modify them
in any way.
- Never attach any objects such as cu­
pholders or telephone mountings to the
surfaces covering the airbag units.
- For cleaning the horn pad or instrument
panel, use only a soft, dry cloth or one
moistened with plain water. Solvents or
cleaners could damage the airbag cover
or change the stiffness or strength of the
material so that the airbag cannot de­
ploy and protect properly.
- Never repair, adjust, or change any parts
of the airbag system .
- All work on the steering wheel, instru­
ment panel, front seats or electrical sys­
tem (including the installation of audio
equipment, cellular telephones and CB
radios, etc .) must be performed by a
qualified technician who has the training
and special equipment necessary.
- For any work on the airbag system, we
strongly recommend that you see your
authorized Audi dealer or qualified work­ shop.
- Never modify the front bumper or parts
of the vehicle body.
- Always make sure that the side airbag
can inflate without interference:
- Never install seat covers or replace­
ment upholstery over the front seat­
backs that have not been specifically
approved by Audi . -
Never use additional seat cushions that
cover the areas where the side airbags
inflate.
- Damage to the original seat covers or
to the seam in the area of the side air­
bag module must always be repaired
immediately by an authorized Audi
dealer .
- The airbag system can be activated only
once. After an airbag has inflated, it
must be replaced by an authorized Audi
dealer or qualified technician who has
the technical information, training and
special equipment necessary.
- The airbag system can be deployed only
once . After an airbag has been deployed,
it must be replaced with new replace­
ment parts designed and approved espe­
cially for your Audi model version. Re­
placement of complete airbag systems
or airbag components must be per­
formed by qualified workshops only.
Make sure that any airbag service action
is entered in your Audi Warranty
& Main­
tenance booklet under
AIRBAG REPLACE­
MENT RECORD .
-In accidents when an airbag is deployed,
the vehicle battery separates the alterna­
tor and the starter from the vehicle elec­
trical system for safety reasons with a pyrotechnic circuit interrupter.
- Work on the pyrotechnic circuit inter­
rupter must only be performed by a
qualified dealer -risk of an accident!
- If the vehicle or the circuit interrupter
is scrapped, all applicable safety pre­
cautions must be followed.
@ For the sake of the environment
Undeployed airbag modules and preten­
sioners might be classified as Perchlorate Material -special handling may apply, see
www.dtsc.ca.gov/hazardouswaste/per­
chlorate. When the vehicle or parts of the restraint system including airbag modules
safety belts with pretensioners are scrap­
ped, all applicable laws and regulations
must be observed. Your authorized Audi
1J1-

will have no warning from a sudden in­
crease in engine speed as with a front­
wheel drive vehicle. A lways drive at
speeds wh ich are suited to the road con­
ditions -risk of crash .
Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimizes the
availability of electrical energy for starting
the engine.
If a vehicle with a conventional energy system
i s not driven for a long period of time, the bat­
tery is discharged by idling current consumers
(e.g. immobilizer) . In certain circumstances it
can result in there being insufficient energy
avai lab le to start the engine.
I ntelligen t energy management in your vehi­
cle handles the distribution of electrical ener­
gy . Starting ability is marked ly improved and
the life of the battery is extended .
Basically, energy management consists o f
battery diagnosis, idling current manage­
ment
and dynamic energy management.
Battery diagnosis
Batt ery d iagnosis continuously dete rmines
the state of the battery. Sensors determine
battery voltage, battery current and battery
temperature. This determines the current
state of charge and the power of the battery.
Idling current management
I dling current management reduces energy
consumption while the vehicle is stand ing.
With the ignition switched off, it contro ls the
energy supply to the various electrica l compo­
nents . Data from battery diagnosis is consid­
ered.
Depending on the battery's state of charge,
individual consumers are gradually turned off
to prevent excessive discharge of the battery
and thus mainta in start ing capability.
Intelligent technology 191
Dynamic energy management
While the vehicle is being driven, dynamic en­
ergy management distrib utes the energy gen ­
erated according to the needs of the individ u­
al components. It regulates consumption, so
that more e lectrical energy is not being used
than is being generated and ensures an opti­
mal state of charge fo r the battery .
{!) Tips
- But even energy management cannot
negate the limits of physics. Consider
that the power and life of a battery are
limited .
- If start ing ability is threatened, the indi­
cator light(•] appears¢
page 17.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severe ly taxed in short-distance
driv ing, in city traff ic and during the cold time
of year. Abundant electrical energy is re­
quired, but on ly a little is generated . It is also
c rit ical if the engine is not running and electri­
ca l components are turned on. In this in­
stance ene rgy is be ing consumed but none is
being generated .
It is in precisely these situations that you will
notice energy management actively regulat­
in g the distribution of energy.
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, electr ical compo ­
nents are gradually cut back or switched off .
T h is reduces energy consumption and main­
tains starting capability over a longer period .
Some of the convenience functions may not
operate, such as the interior lights or the
power seat adjustment. The convenience
functions will be available again when you
switch on the ignition and start the engine.

192 Intelligent technology
With the engine turned off
If you listen to the radio, for example, with
the engine turned off or use othe r MMI func­
tions, the battery is being discharged .
If sta rting capability is jeopa rdized due to en­
e rgy consumpt ion, the fo llowing warning ap­
pears in the MMI display:
Please start the engine soon or the system
will be turned off.
The warning ind icates that the system will be
turned off automatically after 3 minutes.
If
you wish to continue using the functions, you
have to start the engine.
With the engine running
Although electrical energy is generated when
the vehicle is be ing driven, the battery can be­
come discharged . This happens most ly when
l ittle energy is be ing generated a nd a great
deal consumed and the battery's state of
cha rge is not optimal.
To br ing the energy balance back into equili­
b rium, consumers which require especially
la rge amounts of energy are tempo rarily cut
back or switched off. Heating sys tems in par­
ticular requi re a great dea l of energy . If you
notice, for example , that the heated seats* or
the heated rear window are not heating, they
have been temporar ily cut back or switched
off. These systems will be ava ilable again as
soon as the energy ba lance has been restored.
You will a lso notice that engine idle speed has
been increased slightly. This is norma l and not
a cause for concern . By increasing engine idle
speed the add itional energy required is gener­
ated and the batte ry is charged.

-Apply the parking brake.
- Move selector lever of automatic trans-
mission to "P" (Park); put manual trans­
mission in Neutral.
- Always let the engine cool down . Hot
components will burn skin on contact.
- To reduce the risk of being burned, never
open the hood if you see or hear steam
or coolant escaping from the engine
compartment . Wait until no steam or
coolant can be seen or heard before care­
fully opening the hood .
- Keep children away from the engine com­
partment .
- Never spill fluids on hot engine compo­
nents. They can cause a fire.
- Never touch the radiator fan. The auxili­
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool­
ant system is pressurized and hot cool­ ant could spray out .
-Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri­
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com­
partment could start a fire.
- Keep an approved fire extinguisher im­
mediately available.
- To avoid electrical shock and personal in­
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
-If you must perform a check or repair
with the engine running:
Checking and filling 217
- First, fully apply the parking brake,
move selector lever of automatic trans­
mission to "P" (Park); put manual
transmission in Neutral.
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get­
ting caught in the radiator fan, V -belts
or other moving parts, or from contact­ ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.
- Minimize exposure to emission and
chemical hazards~,& .

226 Check ing and filling
• Read the brake fluid level from the brake
fluid reservoir ¢
fig. 173, ¢ page 218,
fig . 169.
The brake fluid level must be be ­
tween the "MIN" and "MAX" markings.
The brake fluid reservoir is located at the rear partition of the engine compartment on the
left side ¢
page 218 .
The fluid level may drop slightly after some
time due to the automatic adjustment of the brake pads . This is not cause for alarm .
I f the brake fluid level falls
considerably be­
l ow the "MIN" mark, the brake wa rning/indi­
cator light (U .S . mode ls:
1111 , Canadian
models :. ) will come on
¢ page 15. Do not
continue to operate the vehicle. The complete
brake system should be thoroughly checked
by an authorized Audi dealer or qualified
workshop and the cause corrected . If the
brake fluid level is too low, the brake warn ing/
i ndicato r light w ill illuminate . Contact an au­
thor ized Audi dealer
imm ediat ely .
@ Tips
The brake f luid reservoir is located under­
neath the cove r.
Changing brake fluid
Have the brake fluid changed by an experi­
enced technician .
Brake fluid absorbs moisture from the a ir . If
the water content in the brake fluid is too
h igh, corrosion in the brake system may result
after a per iod of t ime . The bo iling po int of the
b rake fluid w ill also decrease considerably and
decrease braking performance.
Therefore, the brake flu id must be changed
ev ery two years. A lways use new brake fluid
which confo rms to Fede ral Motor Vehicle
S tanda rd "FMVSS 116 DO T 4".
The brake flu id reservoir can be difficult to
reach, therefo re , we recommend that you
have the brake fl uid changed by yo ur au tho r­
ized
Audi d eale r. Your dea le r has the correct tools, the
right brake flu id and the know -how
to do this for you.
A WARNING
'-
- Brake flu id is poisonous. It must be stor-
ed only in the closed or iginal container
out of the reach of children!
- Brake failure can resu lt from o ld or inap­
propriate brake f lu id. Observe these pre­
cautions:
- Use only brake f luid that meets SA E
specifi cation
J 1703 and conforms to
Federa l Motor Vehicle Standard 1 16 .
Always check with your authorized Audi
dealer to make sure yo u are using the
correct brake fluid. The correct type of
brake flu id is also ind icated on the
brake f lu id reservoir.
- The brake fluid must be new. Heavy use
of the brakes can cause a vapor lock if
the brake fluid is left i n the system too
long . This can se riously affect the effi­
c iency of the brakes as well as your
safety . T his could result in an accident.
W Note
Brake fluid will damage the paint of your
vehicle .
@ For the sake of the environment
Because of the prob lem of proper disposal
of brake fluid as well as the spec ial tools
required and the necessary expertise, we
recommend that you have the brake flu id
changed by your autho rized Aud i deale r.
Battery
General information
Under normal operat ing cond itions, the bat­
tery in your Audi does not need any ma inte­
nance. With
high outside temperatures or
long da ily drives we recommend that you have
the e lectrolyte leve l che cked by an autho rized
A udi dealer or qualified workshop. The elec­
trolyte level should also be checked each time
the battery is charged
¢ page 229. ..,_

Have the battery checked when you take your
vehicle in for service. Yo u are well advised to
replace a battery that is older than 5 years.
W ith certa in types o f airbag deployment, the
battery is disconnec ted from the vehicle elec ­
trica l system for safety reasons
c::> &. in Re­
pair, care and disposal of the airbags on
page 156.
Di sconn ecting the battery t erminal s
Some vehicle functions (power w indow regu­
l ators, for example) are lost if the battery ter­
minals are disconnected . These functions have
to be re learned after the battery terminals are
connec ted again. To prevent this, the battery
should only be disconnected from the vehicle
e lectrical system when absolutely necessary
for repairs .
Vehicl es not driven for long p eriod s
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cu t back or switched off .
This reduces energy consumption and main ­
tains starting capability over a longer per iod
c::> page 191.
Some of the conven ience functions may not
operate, such as the inter ior lights or the
power seat adjustment. The conven ience
functions will be ava ilable again whe n you
turn on the ignition and sta rt the eng ine.
Winter operation
During the winter months, battery capacity
tends to decrease as temperatures drop . This
i s because more powe r is also consumed while
start ing , and the head lights, rea r window de­
fogger, etc., are used more often .
Avo id unnecessary power consumption, par­
ticularly in c ity t raffic or when t rave ling on ly
short d istances. Let you r authorized Audi
dea le r che ck t he capacity of the vehicle bat­
t ery before w inte r sets in
