Fuel and Refueling
Fuel and Refueling
Fuel
Fuel supply
Using the right fuel helps keep the environment
clean and prevents engine damage.
Fuel recommendation
The fuel recommended for your vehicle is unlead­
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rating of 91 AKI (95 RON). For more
information on TOP TIER Detergent Gasoline,
p lease go to the official website
(www.toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label located
on the ins ide of the fuel filler flap . This rating
may be specified as AKI or RON.
Your vehicle may also be operated using unlead­
ed regular gasoline with a minimum octane rat­
ing of 87 AKl/91 RON . However, using 87 AKI/91
RON octane fuel w ill slightly reduce engine per­
formance.
Use unleaded gasoline only. Unleaded gasoline
is available throughout the USA, Canada, and in
most European countries . We recommend that
you do not take your vehicle to areas or countries
where un leaded gaso line may not be available.
For more information on refueling your vehicle,
see
r::;, page 190.
Octane rating
Octane rating indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . Therefore, buy ing
the correct grade of gasoline is very important to
he lp prevent poss ible engine damage and a loss
of engine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
i n gs that can usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
- Regular Grade: 87 -90 AKI
188
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON +MON)/
2
RON = Research Octane Number
MON= Motor Octane Number.
CJ) Note
- Do not use any fue l with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage will occur.
- Do
not use leaded gasoline. The use of lead­
ed gasoline will severely damage your vehi­
cle's catalytic converter and its ability to
control exhaust emissions.
Blended gasoline
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixt ure meets the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock index must be 87 AKI or higher.
- Blend must contain no more than 3% metha-
nol.
- Blend must contain more than 2% co-solvents.
Blend of gasoline and ethanol (grain alcohol or
ethyl alcohol)
-Anti-knoc k index must be 87 AK I or higher.
- Blend must not contain more than 15% etha-
nol.
- Vehicles with flexib le fue l eng ine: blend must
not contain more than 85% ethanol.
Blend of gasoline and MTBE
-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 es­
pecially well for winter or summer dr iv ing . Dur-
i ng seasonal change-ove r, we suggest that you .,.

fill up at busy gas st ations where the season al
adjustment is more likely to be made in time .
(D Note
-Fu els con taining a high pe rcentage of etha­
no l such as ESQ and EBS may only be used in
vehicles with flexible fuel engines. Using high ethanol f uel in veh icles not equ ipped
with flexib le fue l engines can cause severe
engine damage.
- Methanol fuels which do not meet these re­ quirements may ca use corros ion and dam­
age to plast ic and rubber components in the
fuel system.
- Do not use fuels that fail to meet the spec i­
fied criter ia in this chapter.
- If you are unable to determine whether or
not a particular fuel blend meets the spec i­
fications, ask your service station o r its fuel
supplier.
- Do not use fue l for wh ich the contents can­
not be identif ied.
- Fuel system damage and performance prob­
lems result ing from the use of fuels differ­
ent from t hose specif ied a re not the respon­
s ibility of Audi and are not covered under
t h e New Veh icle o r the Emiss io n Control
System Wa rra nt ies.
- If yo u experience a loss of fue l economy o r
driveability an d pe rform ance prob le m s du e
to t he use of one of these fuel blends we
,
recommend that you switch to unb lended
fuel.
Ethanol fuel (Bio-ethanol)
Applies to: ve hicles with flex ible fuel engine
You can recognize vehicles wi th a flexible fuel
engine by looking at the label on the inside of the fuel filler flap.
Ve hicl es w ith flex ible f uel engines may be oper­
ated w ith b io -e thanol fuels such as EBS (85%
ethano l and 15% gasoline) or with un leaded gas­
oline (91 AKI/ROZ 95) . The ve hicle may a lso be
a:, operated with a mixture of these fuels. a:, ...... N r--. N ...... 0

Fuel and R efueling
Your fuel consumpt ion w ill increase when using
bio-ethano l fue ls due to the lower amount of en­
ergy conta ined per un it vol ume in ethanol.
Warming up the flexible fuel engine in low
temperature s
Due to the chemica l composition of b io -ethanol,
a certa in amount of fue l ends up in the engine o il
when driving short distances in very low temper­
atures. This fuel evaporates again when the en­
gine is warmed up.
II Please warm up eng ine .
If the drive r message appears in the instr ume nt
cluster disp lay, drive with a warm engine to re ­
duce the oil leve l.
(D Note
- N ever fill wi th metha no l o r with a higher
percentage of b io -ethanol than 85% (E85).
A highe r percentage of bio-ethanol in the
fuel can cause damage to the engine or to the fuel system.
- If you use on ly E85, it is recommende d to
fill the fue l tank complete ly w ith unleaded
premium g rade gasoline every 5,000 mi les.
- If you expe rience starting, rough id le or hes ­
itat ion d riveab ility prob lems, f ill the fuel
tank complete ly w ith unleaded p remium
grade gaso line and drive it norma lly until
t he gaso line is used. See your author ized
Audi dea ler if the problem persists.
- Inform your author ized Audi dealer that you
are ope rating o r have operate d the vehicle
w ith EBS.
- Read and follow the i nformat ion and tips
abou t gasoli ne

(D Tips
It may take longer to start the engine when
the outs ide temperat ure is very cold. If possi­
ble, use w inte rize d fue l if tempe ratures are
below free zing.

Fuel and R efue li ng
Gasoline additives
A major concern among many auto manufactur­
ers is carbon deposit build-up ca used by the type
of gasoline you use .
Although gasoline grades d iffer from one manu­
facturer to another, they have certain things in
common. All gasoline grades contain substances
that can cause deposits to collect on v ita l engine
parts, such as fue l injectors and intake valves . Al­
though most gasoline brands include addit ives to
keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more information on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas.com).
After an extended period of using inadequate
fue ls, built-up carbon deposits can rob your en­
g ine of peak performance.
CD Note
- Damage or ma lfunction due to poor fuel
quality is not covered by the Audi New Vehi­
cle Limited War ranty.
- Do not add afterma rket fuel add it ive prod­
ucts to yo ur fuel tank.
Refueling
Fuel filler neck
The fuel filler neck is located on the r ight rear
side panel behind the fuel f iller flap .
If the power locking system should fail, you can
still open the flap manually -for detailed instruc­
tions see
c:> page 192 .
You can find the fuel tank capacity of your vehicle
in
c:>page 244 .
The label on the inside of the fuel filler flap tells
you the correct fue l for your vehicle. For more in­
formation about fuel specifications , see
c:>page 188 .
Your veh icle fuel tank has an on-board refuelling
vapor recovery system . This feature he lps to pre­
vent fuel vapors from escaping from the tank and
190
po lluting the environment whi le you refuel your
veh icle. In order to fill the tank proper ly while
protecting the env ironment, please follow th is
refueling procedure carefully.
A WARNING
Under normal operating conditions, never car­
ry additional fuel containers in your car. Gas
can isters and other containers used to trans­
port fue l can be dangerous. Such containers,
f ull or empty, may leak and could cause a fi re
in a co llision.
If you mus t transport fuel to
use for your lawn mower , snow blower, etc.,
be very careful and always observe local and
state laws regarding the use, transportation
and storage of such fuel containers. Make cer­
tain the container meets industry standards
(ANSI/ASTM F852 -86) .
CD Note
Never drive your vehicle until the fuel tank is
complete ly empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter the exhaust system and damage the catalytic
converte r.
