A WARNING
1
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 cup
holders 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
Airbag system 123
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 authori zed 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
t enance booklet under
AIRBAG REPLACE
MENT RECORD .
-For safety reasons in severe accidents,
the alternator and s tarter are separa ted
from the vehicle battery with a pyrotech
nic 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/hazard o u swaste/ per-
ch [orate . When the vehicle or parts of the
restraint system including airbag modules
and safety belts with pretensioners are
scrapped, all applicable laws and regula
tions must be observed. Your authorized
Audi dealer is familiar with these require
ments and we recommend that you have
your dealer perform this service for you.

146 Intellig ent technolog y
Other road users must not be put at risk -
yo u may cause an acc ident!
- Before descending a steep grade, reduce
speed and shift transmission into a lower
gear or lower driving position . Do not
ride the brakes or ho ld the pedal down
too long or too often . This cou ld cause
the brakes to get hot and d iminish brak
ing efficiency .
- Do not "ride the brakes" by resting your
foot on the pedal when you do not intend
to brake . Thi s may cause the b rakes to
overheat, premature wea r and inc reased
stopp ing distance.
- Under certain climat ic and operating
condit ions such as passing through wa
ter, driving in heavy ra in or after wash ing
the vehicle, the effectiveness of the
brakes can be reduced . In winter, ice can
accumulate on the brake pads, linings,
discs and drums. Cautiously apply brakes
for a test . Brakes will dry and ice coat
ings w ill be cleaned off after a few cau
t ious brake applications .
- Driv ing for an extended period of time on
salt-covered roads w ithout us ing your
brakes can also affect braking efficiency .
Clean off accumulated salt coating from
brake discs and pads w ith a few cautious
brake applicat ions.
- If you damage the front spoiler, or if you
ins tall a different spoiler, be su re the air
flow to the front brakes is not obstruct
ed. Otherwise the brake system co uld
overheat red ucing the effectiveness of
the ent ire brake system.
- Failure of one brake circuit will impair
braking capab ility, resulting in increased
stopp ing distance. Avoid driv ing the vehi
cle and have it towed to the nearest au
thorized Aud i dealer or qualified work
shop .
- Never let the vehicle roll to a stop w ith
the engine shut off .
- If the brake booster is not working, for
example when tow ing your vehicle, or
because the b rake booste r has somehow
been damaged, the brake pedal must be pressed considerably harder to make up
for the lack of booster assistance .
Power steering
When the engine is running, power steering
makes i t easier for the driver to s teer .
Power steering helps the driv er steer the vehi
cle with litt le physica l effort.
If the engine is not running, the power steer
ing system is also not working . In this case ,
you wi ll find it extremely d ifficu lt to turn the
steering wheel.
If you turn the steering fully to the left or
rig ht when the vehicle is stationary, you p lace
a very heavy load on the power steering sys
tem. Turning the steering wheel fully to the left or right will cause noise in the system. It
also reduces engine id le speed.
(D Note
Do not hold the steering t urned fu lly to
the left or r ight for more than 10 seconds
when the engine is running . There is a r isk
of damage to the power steering system .
(D Tips
-In the event of a power steering system
failure, or if the engine is not running
(while being towed), you will still be ab le
to steer the vehicle. However, you will re
quire more effort to do so .
- If the powe r stee ring system has a leak
or is defect ive , you should immediately
contact a qualified wor kshop .
- The power steer ing system req uires a
special hydraulic fl uid. The power steer
ing fluid reservoir is located in t he en
gine comp artment. The co rrect hydrauli c
fluid level is important for proper opera
tion of the power steering system. The
power steering fluid level is checked ac
cording to the Audi maintenance service
schedule.

-Have you r vehicle maintained properly
and in accordance with the service rec
ommendat ions in your Warranty
& Main
tenance booklet.
- Lack of proper maintenance as well as
improper use of the vehicle will impair
the function of the Emission Control Sys
tem and could lead to damage.
Sporty driving
Warming up and cooling down
By carefully warming up and cooling down
your vehicle, you can he lp ensure that it is not
overstressed unnecessarily during sporty driv
ing.
When warming up, the vehicle is driven at a maximum engine speed of 6000 RPM
(Vl0 engine) or 7000 RPM (V8 engine) in or
der to raise the engine oil temperature to a minimum of 140 °F (60 °(). The tires also on
ly reach their full road holding capability once
they have warmed up.
The cooling fan can continue to run in your ve hicle after the engine is switched
off. H owev
er, driving the vehicle to cool it down is part ic
ularly important. During sporty driving, the
engine and brakes, the exhaust system, and
the t ransm ission all become extreme ly hot.
Before you park the vehicle, you shou ld d rive
it for a few mi les/kilometers at light load in
the low rpm range to allow it to coo l down .
Driving on a track
Before you take your vehicle out on a track,
ensure that it is in perfect condition. For ex
ample, you should check the tire tread and the brake pads . It is best to increase t ire pressure
by about 0 .3 bar .
When driving on a track, oil consumption may be somewhat higher than in "normal" opera
tion
¢ page 17 4 .
You shou ld definitely inspect your vehicle af
ter subjecting it to severe condit ions. Are the
brake pads OK? Is there anything unusual
Dri vin g and en vironm ent 151
about the ti res, including the inner and outer
sidewa lls (e.g . tread, blistering)? Are the air
intakes free of leaves and tire dust? Is the o il
l evel OK?
Your authorized Audi dea ler or qua lified work
shop will be happy to undertake an inspection
before and after use on the race track.
_& WARNING
-
Some race tracks (e.g. steeply banked
turns) may affect the response of the ESC.
(D Tips
- Review the track requirements and con
ditions before you start driving.
- When driven on a race track, all vehicle
parts are severe ly stressed. This can re
sult in increased wear.
Operation and maintenance
Fuel economy, env ironmenta l impact, and
wear on your eng ine, brakes and tires la rgely
depend on three facto rs:
- your personal driving style
- operating conditions
- technical limitations
By havi ng your ve hicle reg ularly se rviced by an
a uthorized Aud i dea le r helps to ens ure that i t
runs properly and economica lly. The condition
of your vehicle not only affects its safety and
ability to ho ld its va lue, it a lso affects
f u el
consumption .
The amount of oi l used is re lated to engine
load and speed .
It is normal for the oil consump tion of a new
engine to reach its lowest value after a certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before yo u can p rope rly
assess oil consumpt io n.
Th is also app lies to fue l consumption and en-
gine o utp ut.

Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and

The engine oil and oil filter must be changed
according to the mi leage (kilometers) and
time interva ls specified in your vehicle's War

& Maintenance booklet. Do not exceed
t hese intervals -harmful deposits from old
engine o il can reduce engine performance and
can lead to expensive engine repairs .
Changing the o il at the recommended inter
vals is so very important because the lubricat
ing properties of oil decrease gradually during
norma l vehicle use . If you are not sure when
you have your oi l changed, ask your author
i zed A udi Service Advisor.
Under some circumstances the engine o il
should even be changed more frequently .
Change o il more often if you drive mostly
short distances, ope ra te the vehicle in dusty
areas or mostly under s top -and-go traffic con
d itions, or when yo u use your vehicle whe re
temperatures stay below freezing point for
l ong periods.
D etergen t additives i n the o il w il l make fresh
oil look dark after the eng ine has been run

Engine oil consumption
The engine in your vehicle depends on an ade
quate amount of oil to lubricate and cool all
of its moving parts .
In order to provide effective lubrication and
cooling of interna l eng ine components, all in
te rnal combust io n engines consume a certain
amount of oil. Oil consumpt io n va ries from
engine to engine and may change sig nifican tly
ove r the life of the engine. Typically, engines
with a spec ified break -in pe riod (see
¢
page 150) consume more oil duri ng the
break-in pe riod than they consume afte r oi l
consumption has stabili zed.
U nder normal cond itions , the rate of oi l con
s u mption depends on t he q uality and viscos ity
of the oil, the RP M (revolut ions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac
tors are the amount of oil dilut ion from water
condensa tion or fue l residue a nd the oxida
tion level of the oi l. As any eng ine is subject to
wear as mileage builds up, t he oil co nsump
t ion may incre ase over time until repla cement
of wo rn components may be come necessary.
With a ll these va riab les coming into p lay, no
standard rate of oil consumpt io n can be es

178 Checking and filling
Brake fluid
Hove the brake fluid changed by an experi
enced technician .
Brake fluid absorbs moisture from the air. 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
brake fluid w ill also decrease considerably and
decrease b rak ing performance .
Therefore, the brake f lu id must be changed
every two years . Always use new brake fluid
which conforms to Federal Motor Vehicle
Standard "FMVSS 1 16 DOT 4".
Brake fl uid is rep laced according to the Audi
maintenance service schedule. Your author
ized Audi dealer is equipped with the necessa
ry special tools and replacement parts, has
the necessary expe rtise, and can d ispose of
the used fluid .
.&_ WARNING
- Brake fluid is po iso nous. It mus t be s to r
ed on ly in the closed orig inal con taine r
o ut o f th e reac h of children!
- Br ake f ailure can resul t from old o r in ap
propr iate brake fluid. Observe these pre
caut ions:
- Use o nly brake fluid that meets SAE
specification
J 1703 and co nfo rms to
Federal Motor Vehicle Sta ndard 116 .
A lways check wi th you r a uthori zed Aud i
dealer to m ake sur e you are u sing the
correct br ake f luid. The co rrec t type of
b rake fluid is a lso indica ted on the
b rake fluid reservoir .
- The brake flui d must be new. Heavy use
of the brakes can ca use a vapor loc k if
the brake fl uid is left in t he system too
l o ng. This can ser io usly affect the effi
ciency of the brakes as well as yo ur
safety. This could result in an acc ident.
Brake fluid will damage the paint of your
veh icle.
{® For the sake of the environment
Because of the p rob lem of proper disposal
of brake fluid as well as the spec ia l too ls
required and the necessary expertise, we
recommend that you have the brake flu id

Battery
General information
All work on the ba ttery requires technical
knowledge.
The battery is located be hind the cov er in the
l u ggage compa rtment. Remove the cover by
pu shing i t to the left an d lift ing it o ut.
The battery is practically maintenance-free
and is checked as pa rt of your ve hicle's main
tenance se rv ices .
You are we ll advised to replace a battery that
i s older tha n 5 yea rs .
Disconnecting the battery terminals
Some vehicle f unctions (power window reg u
l ators, for example) are lost if the battery te r
mina ls are disconnected. T hese functions have
to be relearned after the battery termina ls are
co nn ected aga in . T o p revent th is, t he battery
shou ld only be disconnected from the ve hicle
elect ric al sy stem w hen abso lutely ne cessary
f or rep airs.
Vehicles not driven for long periods
The battery becomes d ischarged due to quies
cent current consume rs even when the vehicle
is not used. With extended pe riods of non-use
in t he
cold season, yo u should have t he ve hi
cle b attery removed by an autho riz ed Aud i
dealer or qualif ied workshop and stored in an
frost-free place. T his prevents the battery
from "freezing" and thereby being destroyed.
D uring the
warme r seasons it is enough to
disco nnect the battery negat ive terminal. Oc-
cas ionally charge a disconnected battery.
