208 Fuel supply and filling your fuel tank
-Anti -knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE .
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well 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.
CD Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in vehicles with flex ible fuel en­
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l eng ines
can cause severe engine damage.
- Methanol fuels which do not mee t these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel for which the contents
cannot be identif ied.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility 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 driveab ility and performance prob­
le ms due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (B io-ethanol)
App lies to veh icles : w ith flex ible fue l en g in e
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flap.
Vehicles with flexible fuel engines may be op­
erated with bio -ethanol fuels such as E85
(85% ethanol and 15% gasoline) or with un­
leaded gasoline (91 AKI/ROZ 95) . The vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption w ill increase when us­
ing bio-ethanol fue ls due to the lower amount
of energy contained per unit volume in etha­
nol.
Warming up the flexible fuel engine in
low temperatures
Due to the chemical composition of b io-etha­
nol , a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures. This fue l evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru­
ment cluster display, drive with a warm en­
gine to reduce the o il level.
CD Note
- Never fill with methanol o r with a higher
percentage of b io-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fue l system.
- If you use only E85, it is recommended
to fill the fuel tank complete ly with un­
leaded premium grade gaso line every
5,000 miles.
- If you experience starting, rough id le or
hesitation driveability problems, fill the
fue l tank comp letely with unleaded pre­
m ium grade gasoline and dr ive it nor­
mally until the gasoline is used. See your
authorized Audi dealer if the problem
persists .

216 Check ing and filling
temperatures stay below freezing point for
long periods.
Detergent addit ives in the o il w il l make fresh
oil look dark after the eng ine has been run­
ning for a short time . This is norma l and is not
a reason to change the oi l more often than
recommended.
D am age or m alfunc tions du e to lack of
m ainten ance
It
is essential that you change your oil at the
recommended in tervals using only engine o il
that complies with Audi oi l standard
VW 502 00. Your Limited New Vehicle War­
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
Maintenance book let . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re­
pa ir Orders that all scheduled ma intenance
was performed in a t imely manner.
Eng ine 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
cool ing of internal engine components, a ll in­
ternal combustion eng ines consume a certa in
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typica lly, engines
with a specif ied break-in period (see
¢
page 187) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con­
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road condit ions . Further fac­
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to wear as mi
leage builds up, the oil consump­
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev ­
el, see
Note .
If
the yellow engine oil leve l warning symbo l
I! in the instrument cluster lights up, you
shou ld check the oil leve l as soon as possib le
¢
page 217. Top off the oil at your earliest
convenience ¢
page 217.
A WARNING '"---
Before you check anythi ng in the engine
compartment, always read and heed all
WARNINGS¢
A in Working in the engine
compartment on page 212.
(D Note
Driving w ith an insufficient o il level is like­
ly to cause severe damage to the engine .
(D Tips
-The oil pressu re warn ing display . is
not an indic ator of the oil l evel. Do not
r el y on it . In stea d, check th e oil l eve l in
y our engin e at regular inter val s, pref ­
erably ea ch time you r efu el, and alwa ys
before go ing on a long trip .
-If you have t he impression yo ur engine
consumes excessive amoun ts of o il, we
recommend that you consu lt an author­
ized Aud i dea ler to have the cause of
your concern properly diagnosed. Keep in m ind that the accurate measu rement of
oil consumption requ ires great care and
may take some time. An authorized Aud i
dealer has instructions about how to
measu re oil consumption accurately.

218 Check ing and filling
@ 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 regu lations
when disposing of empty oil containers.
Changing the engine oil
We recommend thot hove your oil changed by
an authorized Audi dealer or a qualified serv­
ice station.
Before you check anything in the engine com­
partment,
a lways r ea d and heed all WARN­
ING S ¢ & in Working in the engine compart­
ment on page 212.
The engine oil must be changed according to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di­
minish gradually during normal vehicle use .
Under some circ umstances the engine oi l
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 ­
d itions, or have your veh icle where tempera­
tures remain below freez ing fo r extended pe­
riods.
Detergent addit ives in the o il w ill make fresh
oil look dark after the eng ine has been run­
n ing fo r a short time. This is norma l and is not
a reason to change the oil mo re often than
recommended.
Because of the problem of proper disposal ,
a long w ith the special tools and necessary ex­
pertise required, we strong ly recommend that
you have your o il changed by an authorized
Audi de ale r or a qualified service station.
If you cho ose t o c han ge your oil yours elf ,
please note the following important informa­
tion :
A WARNING
To reduce the risk of personal injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en- gine oil, let the engine cool down to the
touch.
- When removing the o il dra in 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
n ing down you r arm.
- Dra in the oil into a container designed
for this purpose, one large enough to hold at least the tota l amount of oil in
your engine.
- Engine oil is poisonous. Keep it we ll out
of the rea ch of childre n.
- Continuous contact with used eng ine o il
is harmfu l to your sk in. Always protect
your skin by washing oil off tho ro ughly
with soap and wate r.
@ Note
Neve r mix oil additives with your engine
oi l. These additives can damage your en­
g ine and adversely affec t you r A ud i L imit­
ed New Veh icle War ranty.
@ For the sake of the environment
- Before changing your oil, first make su re
you know where you can prope rly dispose
o f the used oil.
- Always dispose of used eng ine oi l proper ­
ly. Do not dump it on garden soil, wood­
ed areas, into open streams o r down
sewage drains.
- Recycle used engi ne oil by taking it to a
used engine oil collection facility in you r
area, or contact a service station.

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

pair, care and disposal of the airbags on
page 154.
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 185.
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
