202 Fuel supply and filling your fuel tank
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 stations 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 flexible fuel en­
gines. Using high ethanol fuel in vehicles not equipped with flexible fuel engines
can cause severe engine damage.
- 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 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 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
lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (Bio -ethanol)
App lies to vehicles: with flexible fuel e ngi ne
You con 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 (8S% 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 will increase when us­
ing bio-ethanol fuels 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 bio-etha­
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures . This fuel 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 oil level.
CD Note
- Never fill with methanol or with a higher
percentage of bio-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fuel system.
- If you use only E85, it is recommended
to fill the fuel tank completely with un­
leaded premium grade gasoline every
5,000 miles.
- If you experience starting, rough idle or
hesitation driveability problems, fill the
fuel tank completely with unleaded pre­ mium grade gasoline and drive it nor­
mally until the gasoline is used. See your
authorized Audi dealer if the problem
persists.
- Inform your authorized Audi dealer that
you are operating or have operated the
vehicle with E85.
- Read and follow the information and tips
about gasoline

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
Ill in the instrument cl uster lights up, you
shou ld check the oil leve l as soon as possib le

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,
a lw ays rea d an d h eed all WARN­
INGS c::> .& in Working in the engine compart­
ment on page 206.
The engine oil must be changed accord ing to
the intervals specified in your Warranty
&
Maintenance book let. This is very important
because the lubricating properties of oil di­
minish gradua lly during normal vehicle use .
Under some ci rcumstances the engine oi l
should be changed more frequently. Change
oil more often if you drive most ly short dis­
tances, operate the vehicle in dusty areas or under predominantly stop-and-go traffic con­
ditions, or have your vehicle where tempera­
tures remain below freezing for extended pe ­
riods .
Detergent addit ives in the oil w ill make fresh
oil look dark after the engine has been run­ n ing 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 w ith the special tools and necessary ex ­
pertise required , we strongly recommend that
you have your o il changed by an authorized
Audi de ale r or a qual ified servi ce station.
If y ou choo se to c hang e y our oi l y our self,
please note the followi ng 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 run­n ing down you r arm.
- Dra in 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 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 roughly
with soap and wate r.
@ Note
Never mix oil additives with your engine
oi l. These additives can damage your en­
g ine and adversely affect you r A ud i Limit­

@ 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 or 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.

Battery
General information
Under normal operating conditions, the bat­
tery in your Audi does not need any mainte ­
nance. With
high outside temperatures or
long daily dr ives we recommend that you have
the electro lyte level checked by an authorized
Aud i dealer or qualified workshop . The elec­
trolyte leve l should also be checked each time
the battery is charged ¢
page 219.
Have the battery checked when you take your
ve hicle in for service . Yo u are well adv ised to
replace a battery that is older than 5 yea rs .
W ith certa in types of a irbag deployment, t he
b attery is d isconnected from the vehicle elec­
tr ica l system for safety reasons¢.&.

Disconnecting the battery terminals
Some vehicle functions (power w indow regu­
lators , for example) are lost if the battery ter­
m inals a re d isconnected. These func tions have
to be re lea rned after the batte ry term inals a re
connected agai n. T o prevent this , the bat tery
should only be d isconnec ted from the vehicle
e lec tric al system when absolu tely necessa ry
for repairs .

Tires and vehicle load limits
There are limits to the amo unt of load or
weight that any vehicle and any t ire can carry .
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overloading
can not only lead to loss of vehicle contro l,
but c an also damage import ant parts of the
vehicle and can lead to sudde n tire failure, in­
cluding a blowout and sudden deflation that
can cause t he veh icle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded . Vehicle load includes everybody
and everyth ing in and on the vehicle. These load lim
its are technically referred to as the
vehicle's
Gro ss Vehicle Weight R ating
("GVWR").
T he "GVWR" includes t he weight of the basic
vehicle , a ll f actory installed accessories, a f ull
tank of fuel, oi l, coo lant and other f luids plus
maximum load. The max imum load incl udes
the number of passengers that the vehicle is
intended to carry ("seat ing capac ity ") wi th an
assumed we ight of 150 lbs . (68 kg) for each
passenger at a designated seating posit ion
and the total weight of a ny luggage in the ve­
hicle. If you tow a trai le r, the we ight of the
t ra ile r hi tc h and the tongue we ight of the
l oaded tra iler mus t be include d as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating ("GAWR ") is
the max imum load that can be applied a t each
of the veh icle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weig ht Ra ting are listed on the
sa fety comp lian ce s ticke r label loca ted on the
driver's side B-pillar. Yo ur Audi has 4 seat ing
pos itions , 2 in the front and 2 in the rea r fo r
total seati ng capacity of 4. Each seating posi­
t ion has a seat belt c:>
page 132, Safety belts.
T he fact that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
t h at the total weight of whatever is being car­
ried in the vehicle ( includ ing the weight of a
trailer hitch and the tongue weight of the
loaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier tha n the sta ndard we igh ts assumed
mean that less we ight can be carried as lug­
gage.

Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv·
ing style.

_____ ___,.J)
Fig. 185 Rotating tires for more even wear
Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c:> fig. 184 running across the tread. Depend·
ing on the make , there will be six to eight of
them evenly placed around the tire. M ar ks on
the tire sidewall (for example "TWI" or other
symbols) indicate the positions of the tread
wear indicators. Worn tires must be replaced. Different
figures may apply in other countries
c:>& .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden tire blow-out. For this
reason, tire pressure must be checked at least
once a month
c:> page 228.
Driving style
Driving fast around curves, heavy acceleration
and hard braking increase tire wear .
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota­
tion intervals. Please remember the follow­
ing :
- Tire rotation intervals may differ from the
vehicle service intervals outlined in your
Maintenance and Warranty Booklet .
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufacturer's suggested
tire rotation intervals.
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com­
pa red to all wheel drive (quattro).
- Please rotate tires as shown
c:>fig. 185.
- Extra care must be taken when rotating di-
rection-specific tires
c:> page 249 .
Wheel balancing
The wheels on new vehicles are balanced .
However, various situations during everyday
driving can cause them to become unbal­
anced, resulting in vibrations you can usually
feel through the steering wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A wheel must also be rebalanced
when a new tire is installed. .,.

256 Emergency situations
@ Tips
The discharged battery must be properly
connected to the vehicle's electrical sys­
tem. When jump starting or charging the
battery, never connect the negative
ground cable to the battery negative post
because the batte ry manager system must
be able to detect the battery 's state of
charge. Always connect the negative
ground cab le to the negative ground post
of the battery manager control unit.
