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.
Airbag system 171
-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.

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
is not driven for a long period of time , the bat
tery is discharged by idling cu rrent consumers
(e.g. immobilizer). In ce rtain c ircumstances it
can result in there being insuff icient ene rgy
avai lab le to s tart the engine .
I ntelligent energy management in your vehi
cle hand les the d ist ribution of electrical ener
gy. Starting ab ility is marked ly imp roved and
the life of the battery is extended.
Basically , energy management consists of
b atter y dia gno sis, idling curr ent manag e
m ent
and dynami c en ergy m anag emen t.
Battery diagnosis
Battery d iagnosis continuously determ ines
the state of the battery . Sensors determ ine
battery vo ltage, battery curren t and battery
temperature. This dete rm ines the current
state of charge and the power of the battery .
Idling current management
Idling current management reduces energy
consumpt ion wh ile the veh icle is stand ing .
W ith the ignition switched off, it cont ro ls the
energy s upply to the va rio us electr ical compo
nents. Data from battery diagnosis is consid
ered.
D epending on the batte ry's state of charge,
i nd ividual consumers are grad ua lly turned off
to p revent excessive discharge of the battery
and thus maintain starting capability .
Dynamic energy management
W hil e the vehicle is being driven, dynamic en
e rgy management dist ributes t he energy gen-
Int ellig ent technolog y 203
erated according to the needs of the individ u
al components. It regulates consumption, so
that more electrical energy is not being used
than is being generated and ensures an opti
mal state of charge for the battery.
(D 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 t hreatened, the indi
cator light(•] appears¢
page 34 .
What you should know
The highest priority is given to maintaining
star ting capability.
The battery is severe ly taxed in short-distance
driving, in city traff ic and during the cold time
of year. Abundant elect rical energy is re
quired, but only a lit tle is generated . It is also
crit ical if the engine is not running and electri
cal components are turned on. In this in
stance ene rgy is be ing consumed but none is
being genera ted .
It is in precisely these situations that you will
not ice energy management actively regulat
ing the d istribution of ene rgy.
Vehicle stand s for an e xtended period
If you do not drive your vehicle over a period
of several days or weeks, e lectr ical compo
nents are gradually cut back or switched off.
This reduces energy consumption and ma in
ta ins start ing capability over a longer pe riod .
Some of the convenience func tions may not
opera te , such as the interior ligh ts or the
power seat adjustment. The convenience
funct ions w ill be available again when you
switch on the ignition and start the engine.
With the en gine turn ed off
If you listen to the radio, for exam ple, w ith
the engine turned off or use other MMI* func-
tions, the battery is being discharged .

204 Intelligent technology
If starting capability is jeopa rdized due to en
ergy consumption, the following warning ap
pears in the radio or MMI* display:
Please start engine, otherwise system will
switch off in 3 minutes.
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 . Thi s happens mostly when
little ene rgy is being generated and a great
deal consumed and the battery's state o f
charge is not optima l.
To bring the energy balance back into equili
brium, consumers which require especially
l arge amounts of energy are temporarily cut
back or switched off. Heating systems in par
ticular require 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 balance has been restored.
You will also notice that engine idle speed has been increased slightly. This is normal and not
a cause for concern . By increas ing engine idle
speed the add it iona l energy required is gener
ated and the battery is charged.

A WARNING
- While topping off, the oil must not come in contact with hot engine parts - fire
hazard!
- The oil filler cap must be properly se cured to prevent oil from being sprayed
on the hot engine and exhaust system
when the engine is running - fire hazard!
- If your skin has come in contact with the
engine oil, you must subsequently
cleanse it thoroughly .
(D Note
-Check the oil level using the radio or the

Audi dealer or other qualified workshop
to have excess oil extracted if necessary.
-Audi does not recommend the use of oil
additives. They may damage the engine
and adversely affect your New Vehicle
Warranty.
@ For the sake of the environment
- Under no circumstances can the oil come
in contact with the sewage network or
the soil.
- Observe and follow legal regulations
when disposing of empty oil containers.
Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv
ice station .
Before you check anything in the engine com
partment,
always read and heed all WARN
INGS
c::> .&. in Working in the engine compart
ment on page 231.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance booklet. This is very important
because the lubricating properties of oil di
minish gradually during normal vehicle use.
Checking and filling 237
Under some circumstances the engine oil
should be changed more frequently. Change
oil more often if you drive mostly short dis
tances, operate the vehicle in dusty areas or
under predominantly stop-and-go traffic con
dition s, or have your vehicle where tempera
tures remain below freezing for extended pe
riods.
Detergent addi tives in the oil will make fresh
oil look dark after the engine has been run
ning for a short time . This is normal and is not
a reason to change the oil more often than recommended.
Because of the problem of proper disposal,
along with the special tools and necessary ex
pertise required, we strongly recommend that
you have your oil changed by an authorized
Audi dealer or a qualified service station.
If you choose to change your oil yourself ,
please note the following important informa
tion:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your vehicle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot en-
gine oil, let the engine cool down to the
touch.
- When removing the oil drain plug with
your fingers, stay as far away as possible.
Always keep your forearm parallel to the
ground to help prevent hot oil from run ning down your arm.
- Drain the oil into a container designed
for this purpose, one large enough to
hold at least the total amount of oil in
your engine.
- Engine oil is poisonous. Keep it well out
of the reach of children.
- Continuous contact with used engine oil
is harmful to your skin. Always protect
your skin by washing oil
off thoroughly
with soap and water.

-Always follow the operating instructions
provided by the battery charger manu
facturer when charging your battery.
- Never charge a frozen battery.
It may ex
plode because of gas trapped in the ice.
Allow a frozen battery to thaw out first.
- Do not reuse batteries which were fro
zen. The battery housing may have
cracked and weakened when the battery
froze.
- Charge the battery in a well ventilated
area. Keep away from open flame or elec
trical spark. Do not smoke . Hydrogen gas
generated by the battery is explosive.
- To reduce the danger of explosion, never
connect or disconnect charger cables
while the charger is operating.
- Fast charging a battery is dangerous and
should only be attempted by a compe
tent technician with the proper equip
ment.
- Battery acid that may spill during charg
ing should be washed off with a solution
of warm water and baking soda to neu
tralize the acid.
(D Note
Never use a fast charger as a booster to
start the engine. This will seriously dam
age sensitive electronic components, such
as control units, relays, radio, etc., as well
as the battery charger.
Battery replacement
The new battery must have the same specifi
cations and dimensions as the original equip
ment battery.
Intelligent energy management in your vehi
cle is responsible for distributing the electri
cal energy throughout your vehicle
¢ page 203. The intelligent energy manage
ment system will keep the engine battery
charged better then vehicles without this sys
tem . To make sure the additional electrical en
ergy is available once again after you have
changed the battery, we recommend that you
Checking and filling 245
install batteries of the same type and manu
facture only (the same as those installed at
the time your vehicle was delivered). Specifi cations are listed on the battery housing . Your
authorized dealer must code the battery in
the energy management system to enable you
to use the energy management functions cor
rectly after replacing the battery .
If it is not possible to use a battery of this
type , the new battery must have the same ca
pacity, voltage (12 volts), amperage, con
struction and plug sealing .
When installing the battery, make sure the ig nition and all electrical consumers are turned
off .
(D Note
-Make sure the ventilation hose on the
side of the battery is connected, other
wise fumes or battery acid can leak out .
- Vehicles with the Start-Stop-System* are
equipped with a special cycle-proof AGM
battery. Installing a different type of
battery can cause problems in the vehi
cle electrical system. When replacing the
vehicle battery, always install one with
the same specifications as the original
battery.
@ For the sake of the environment
Because of the problem of proper disposal
of a battery, we recommend your author
ized Audi dealer change the battery for
you. Batteries contain sulfuric acid and
lead and must always be disposed of prop
erly in compliance with all environmental
regulations. Disposing of vehicle batteries
improperly is very dangerous to the envi
ronment. •

248 Tire s and whee ls
- Never mount used tires on yo ur vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when driving, al
ways stop as soon as it is safe to do so and check the wheels and tires for dam
age.
