-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-

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-
ch lorate. 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
dealer is familiar with these requirements
and we recommend 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 Sys­
tem performs in a crash. For example, using
tire-rim combinations not approved by Audi ,
lowering the vehicle, changing the stiffness of
the suspension, including the springs, suspen­
sion struts, shock absorbers etc. can change
the forces that are measured by the airbag
sensors and sent to the electronic control unit. Some suspension changes can, for

capacity is limited by tire traction. You
should therefore not drive at excessive
speeds on icy or slippery road surfaces.
- On wet road surfaces, be careful not to
dr ive too fast because the front wheels
cou ld beg in to slide on top of the water
(aquaplaning) . If this should occur, you
will have no warning from a sudden in­
crease in engine speed as with a front·
wheel drive vehicle . A lways d rive at
speeds wh ich are suited to the road con­

Energy management
Starting ability is optimized
Energy management controls the distribution
of electrical energy and thus optimi zes the
availabili ty of electrical energy for s tarting
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 current consumers
(e .g . immobilizer) . In certain c ircumstances it
can result in there being insufficient energy
avai lab le to start the engine.
Intell igent energy management in your vehi­
cle hand les the d istribution of electrical ener ·
gy. Starting ab il ity is markedly improved and
the life of the battery is extended .
Basically, energy management consists of
battery diagno sis, idling current manag e­
m ent
and dynamic en erg y manag ement.
B attery diagnosi s
Battery diagnosis continuously determines
the state of the battery. Sensors determ ine
battery vo ltage, battery current and battery
temperature . This determ ines the current
state of charge and the powe r of the battery.
Idling current management
Idling current management reduces energy
consumption while the vehicle is s tand ing.
W ith the ignition switched off, it contro ls the
energy supply to the various electr ica l compo·
Int ellig ent technolog y 177
nents . Data from batte ry diagnos is is cons id ­
ered.
Depend ing o n the ba ttery's state of cha rge ,
individ ua l cons umers are g radually turned off
to prevent excessive discharge of the battery
and t hus maintain sta rting capability.
Dynamic energy management
While t he vehi cle is being d riven, dynamic e n­
ergy ma nagement dis trib utes the energy ge n­
era ted accord ing to the needs of the individ u­
al components. It regulates consumption, so
that more e lectrical energy is not bei ng used
than is being generated and ensures an opti­
mal state of charge for t he battery.
(D Tips
- But even ene rgy 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 (•) ::ippears
¢ page 16.
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. Ab undant electrica l energy is re­
quired, but on ly a little is generated . It is also
critical if the engi ne 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 ge nerated .
It is in precisely these situations that you will
notice energy management active ly regu lat ·
ing the d istribut ion of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, e lectr ica l compo­
nents are gradually cut back or switched off.
This reduces energy consumption and ma in·
ta ins start ing capability over a longer period .
Some of the convenience func tions may not .,.

operate, such as the inter ior lights or the
power seat adjustment. The convenience
functions will be ava ilable again when you
switch on the ignit ion and start the engine.
With th e engine turn ed off
If yo u listen to the radio, for example, with
the engine turned off or use other MMI fu nc­
tions, the battery is being discharged .
I f sta rting capabi lity is jeopa rdized due to en ­
e rgy consumpt ion, the fo llowing warning ap­
pears in the MMI display:
Please start the eng ine soon or th e syste m
will be turned off .
The warning ind icates that the system will be
turned off automatically after 3 m inutes. If
you wish to con tinue us ing t he functions, you
have to s tart the engi ne.
With the engine running
A lthough electrical energy is generated when
the veh icle is be ing dr iven, the battery can be­
come discharged . T his happens most ly when
little energy is be ing generated a nd a great
deal consumed and the battery 's state o f
charge is no t optima l.
To br ing the energy balance back into equili­
b rium, consumers which require especially
l arge amo unts of energy are tempo rari ly cut
back or switched off. Heating sys tems 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 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 itiona l energy required is gener­
ated and the batte ry is charged .

(D Note
-Be aware that just one tank fi lling with
le ad ed fuel will already seriously de­
grade the performance of the catalytic
converter.
- Do not exceed the correct engine oil leve l
c>page 199.
-Do not drive until the fuel tank becomes
complete ly empty. The engine could mis ­
fire. Unburned fuel could also get into
the exhaust system and this could cause
the catalyt ic converter to overheat.
- Do not turn off the ignition while the ve­
hicle is moving .
- Do not continue to operate your vehicle
under these condit ions, as otherwise fuel
can reach the catalytic converter. This
could result in overheat ing of the con­
verter, requ iring its replacement.
- To assure efficient operat ion of the Emis­
s ion Control System:
- Have your vehicle maintained properly
and in accordance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impa ir
the funct ion of the emission control
system and could lead to damage .
@) For the sake of the environment
Even when the Emission Control System is
operating properly, the exhaust gas can
have a sulfur-like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fuel being used.
Using a d ifferent brand of fuel may help,

Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex ­
haust and noise levels.
Fuel economy, environmenta l impact, and
wear on your engine, brakes and tires largely depend on three factors:
- your personal d riving style
- operating conditions
- technical limitat ions
If you ant ic ipate what you need to do next and
drive economically, you can easily cut your
fuel consumpt ion by 10-15 percent . This sec­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook.
(D Tips
The consumption estimates as published
by ENVIRONMENTAL PROTEC TION AGENCY
( E PA) and Transpo rt Canada may not cor re­
spond to your actual consump tion on the
road, which will vary depending upon vehi­
cle load and speed, road and weather con ­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.,. Avoid unnecessary accelerating and braking.
Vehicles use the most f uel when they a re ac­
ce lerat ing. If you ant icipate what is going to
happe n next, you will need to brake less and,
th us, acce lerate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next traff ic light is red.

196 Checking and filling
-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:
- First, fully apply the parking brake,
move selector lever of automatic trans­
mission to "P" (Park). -
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~& .
