Fuel and Refueling
Gasoline
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
in formation on TOP TIER Detergent Gasoline,
p lease go to the offic ial website
(www.toptiergas.com).
The recommended gasoline octane rating for
your engine can also be found on a label located
on the inside 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 AKI/91 RON. However, using 87 AKI/91
RON octane fuel w ill slightly reduce engine pe r­
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 gasoline may not be available.
For more information on refueling your vehicle,
see
r=;, page 17 4.
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
help prevent poss ible engine damage and a loss
of eng ine performance.
Gasoline most commonly used in the United
States and Canada has the following octane rat­
ings that can usually be found on the filler pump:
- Premium Grade: 91 - 96 AKI
- Regular Grade: 87 - 90 AKI
Fuel and Refueling
Explanation of the abbreviations :
AKI=
Ant i Knock Index= (R+M)/2 = (RON +MON)/
2
RON = Re search Octane Number
MON= Motor Octane Number.
(D Note
- Do not use any fuel with octane ratings low­
er than 87 AKI or 91 RON otherwise expen­
sive engine damage w ill 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 b lended with al­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixt ure meets the follo wing
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-knock index must be 87 AKI or higher.
- Blend must not conta in more than 15% etha-
nol.
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 iving . Dur­
ing seasonal change-ove r, we suggest that you
fill up at busy gas stations where the seasonal
adjustment is more likely to be made in time. ..,.

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 m ust 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 t hat you have
your authorized Aud i dea le r 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 light s):
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
fied workshop sho uld change the bulbs in
gas discharge lamps. There are parts with
sharp edges on the openings and on the
