Checking and Filling
Gasoline
Fuel supply
Using the right fuel helps keep the environment
clean and prevents engine damage .
Fuel recommendation
The fuel recommended for your veh icle is unlead­
ed premium
grade gasoline. Audi recommends
using TOP TIER Detergent Gasoline with a mini­
mum octane rat ing of 91 AKI (95 RON). For more
in fo rmation on TOP TIER Detergent Gasoline,
p lease go to the offic ial website
(www.toptiergas.co m).
The recommended gasoline octa ne rating for
your eng ine can a lso be fo und o n a label located
on the inside of the fue l filler flap. Th is rat ing
m ay be s pec ified as A KI or RON.
Your ve hicle may also be operated us ing unlead­
ed regular gasoline with a minimum octane rat­ in g of 87 AKI/9 1 RO N. However, using 8 7 AKI/9 1
RO N octa ne f uel w ill slightly reduce engi ne pe r­
f o rm an ce.
Use unleaded gasoline only. Unleaded gasoline
i s available throug hout t he USA, Canada, and in
m ost European co untr ies . We recom mend that
you do not t ake your veh icle t o area s or co untries
w here un leaded gaso line m ay not be av a ila ble.

Octane rating
Octane rati ng indicates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignit ion and detonation . The refore, buy ing
the co rrect grade of gasoline is ve ry important to
h e lp p revent poss ible e ngine damage and a loss
of eng ine pe rforma nce.
Gasoline mos t commonly used in the United
S tates a nd C anada has the following octane ra t­
in gs that ca n usually be fo und o n the filler pump:
- Premium Grade: 91 - 96 AKI
- Regular Grade: 87 - 90 A KI
Checking and Filling
Explanation of the abb reviations:
A KI=
A nti K nock Index= ( R+ M )/2 = (R ON+M ON )/
2
RON = Resea rch Octa ne Number
MON= Motor Octane Number.
(D Note
- Do not use any f uel w ith octane ratings low ­
er than 87 A KI or 9 1 RO N ot herwise e xpe n­
sive engine damage w ill occur.
- Do
not use lea ded gasoline . T he use of lead ­
ed gasoline will severe ly damage you r vehi­
cle's catalyt ic converter and its ability to
cont rol exhaust emissions .
Blended gasoline
Use of gasoline containing alcohol or MTBE (methyl tertiary butyl ether)
You may use unlead ed gasoli ne b le nded with al­
c o hol o r MTB E (commonly referre d to as oxyge n­
ates) if the blende d m ix tu re meets the fo llow ing
c rit e ri a:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knoc k 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)
- An ti- kno ck index mus t be 87 A KI or hi gher.
- Blend must not co nta in mo re than 15% etha-
nol.
Blend of gasoline and MTBE
- Anti -knock index must be 87 AKI or h igher.
- Blend must contain not mo re than 15% MTBE .
Seasonally adjusted gasoline
Many gasoline grades a re blended to perform es­
pecially well for w in ter o r su mmer dr iv ing . D ur ­
i ng seasonal cha nge-ove r, we sugges t that yo u
fill up a t busy gas st at io ns w here the seasonal
adjus tme nt is mo re li kely to be made in t ime. ..,.

(D Note
Never drive your vehicle until the fuel tank is
completely empty. The irregular supply of
fuel can cause misfiring. Gasoline could enter
the exhaust system and damage the catalytic
converter.
Fueling procedure
Fig. 135 R ight rear side of the vehicle: opening the fue l
f iller door
Fig. 136 Fu el fil ler door w ith attached fuel cap
The fuel filler door is unlocked or locked by the
central locking system.
Opening the fuel cap
"" Press on the left side of the fuel filler door to
open ¢
fig. 135.
""Unscrew the tank cap counterclockw ise.
"" Place the cap from above on the open fuel filler
door ¢
fig. 136.
Closing the fuel cap
""Screw the tank cap on to the right on the filler
neck until it cannot turn any farther.
""Then press on the left side of the tank door un­
ti l it latches .
Checking and Filling
Once the pump nozzle switches off, the fuel tank
is "full". Do not fill the tank more . Otherwise the
expansion space in the tank will be filled.
The correct fuel type for your vehicle can be
found on a label located on the inside of the fuel
filler door. For additional information on fuel,
see
¢ page 155.
The fuel tank capacity of your vehicle is listed in
the
Technical Data section¢ page 216.
To avo id fuel spilling or evaporat ing from the fuel
tank always close fuel cap properly and com­
pletely. An improperly closed fuel filler cap may
also cause the MIL lamp¢
page 17 to come on.
A WARNING
Not paying attention when fueling or han­
dling fuel incorrectly can lead to fires, explo­
sions or serious injuries.
- Fuel ignites easily and can cause serious
burns and other injuries.
-
-If you do not switch the engine off when fu­
eling and/or do not insert the fuel nozzle
completely into the tank opening, fuel can
leak out or run over. Leaked fuel can ignite
and start a fire.
- Do not use the telephone while fueling. The
electromagnetic rays can cause sparks,
which can ignite fuel vapors and start a fire .
- Do not sit in your vehicle while fueling. If
you must make an exception and enter your
veh icle aga in while fueling, close the door
and touch metal to discharge static electric­
ity before touching the fuel nozzle. Static
electricity can create sparks, which can ig­
nite vapors when fueling.
- Do not smoke or have an open flame in the
area when fueling your vehicle or filling a
fuel container because this increases the
risk of an explosion.
- For your safety, carrying fuel containers in
your vehicle is not recommended. Whether
full or empty, the container can leak and
cause a fire in the event of an accident.
- If you must make an exception and trans­
port a fuel container, note the following:

Bulbs
Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for
you .
It is becoming increasingly more and more diffi­
cult to replace vehicle light bulbs since in many
cases, other parts of the car must first be re­
moved before you are able to get to the bulb .
T his applies especially to the light bulbs in the
front of your car which you can only reach
through the engine compartment .
Sheet metal and bu lb holders can have sharp
edges that can cause serious cuts, pa rts must be
correctly taken apart and then properly put back
together to help prevent breakage o f parts and
long term damage from water that can enter
housings that have not been properly resealed.
For your safety, we recommend that you have
your authorized Aud i dea ler rep lace any bulbs fo r
you, since your dealer has the proper tools, the
correct bulbs and the expertise.
Gas di schar ge la mps (Xe no n ligh ts):
Due to the high electr ical voltage, have the bulbs
rep laced by a qualified technician. Headlights
with Xenon light are identified by the hig h volt­
age st icker.
LED headlights* require no maintenance . Please
contact your authorized Audi dea ler if a bulb
needs to be replaced.
_&. WARNING
Changing Xenon lamps wi thout the necessary
equipment can cause serious personal injury .
- Bulbs are pressu rized and can explode when
be ing changed. Potent ial ris k of injury!
- On veh icles equipped with gas disc harge
bu lbs (Xenon light) life-threatening injuries
can resu lt from improper handling of the
high-vo ltage portions of such lamps!
- Only your authorized A udi dealer or quali­
f ied workshop sho uld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
