Gasoline grade
A pplies to: ve hicles with gasoline engines
The correct gasoline grade is stated on the inside
of the fuel filler door .
The vehicle is equipped with a catalytic converter
and must only be driven with
unleaded gasoline .
Audi recommends using TOP TIER Detergent Gas­
oline. Additiona l information on TOP TIER Deter­
gent Gasoline can be found on the official web­
site (www .topt iergas.com).
The individual gasoline grades are differentiated
by
octane ratings. T his value is given with (R +M)/
2 equating to AKI or in RON.
The following headings match the corresponding
sticker in the fuel fi ller door.
UNLEADED FUEL ONLY MIN. (R+M)/2 87
Regular/ MIN. RON 91 Regular
Use regu lar gasoline with minimum 87 AKI/
91 RON
i::> (@ .
The maximum engine power is only reached if
premium gasoline 91 AKI/ 95 RON is used.
UNLEADED FUEL ONLY PREMIUM MIN . (R
+M)/2 91 / SUPER MIN. RON 95
Using premium gasoline with minimum 91 AKI/
95 RON is recommended.
If premium gasoline is not available, you can also
use regular gasoline 87 AKI/ 91 RON . However
this does reduce the engine power slightly.
({D) Note
-Fill in g the tank just one time with leaded
fuel or other metallic additives will cause
permanent deterioration to the catalytic
converter function.
- When gasoline with an octane rating that is
too low is used, high speeds or heavy engine
load can lead to eng ine damage.
Checking and Filling
(D Tips
The vehicle may be filled with fuel that has a
higher octane rating than what is required by
the engine .
Blended gasoline
Applies to : vehicles wi th gasoli ne e ngi ne
Use of gasoline containing alcohol or MTBE
(methyl tertiary butyl ether)
You may use unleaded gasoline blended with al ­
coho l or MTBE (commonly referred to as oxygen­
ates) if the blended mixture 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-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 not contain 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-over, we suggest that you
fill up at busy gas stat ions where the seasonal
adjustment is more likely to be made in time .
@ Note
-Methanol fuels which do not meet these re­
quirements may cause corrosion and dam­
age to plast ic and rubbe r components in the
fuel system.
- Do not u se fuels that fail to meet the speci-
fied criteria in this chapter.

(UJ) Note
The engine oil leve l mus t not be unde r the

engine damage.
(D Tips
The o il level indica tor in the disp lay is on ly an
informationa l display. If the o il level is too
low, a minimum oi l warning appears in the in ­
strument cluster. Add oil and close the hood.
The current oil level is d isplayed in the Info­
tainment system the next t ime the ignition is
sw itched on.
(D Tips
The engine oil consumption may be up to
0.5 quart/600 m iles (0.S liter/1,000 km), de­
pending on driving style and operating condi­
tions. Consumpt ion may be h igher during the
first 3,000 miles (5,000 km). Because of this,
the eng ine oil level m ust be checked regu lar­
ly. I t is best to chec k each t ime yo u refuel
your veh icle and befo re long d rives .
Ch eck ing and F illing
-In order to prov ide effective lubrication and
cooling of interna l engine components, a ll
internal comb ustion engines consume acer ­
tain amount of oil. Oi l consumption var ies
from engine to engine and may change sig­
nificantly over the life of the engine . Typi­
cally, eng ines with a specified break-in peri­
od consume mo re o il du ring the break-in pe­
r iod than they consume afte r oil cons ump­
t ion has s tabilized.
-Under norma l co ndit io ns, the rate of oil
cons umption depe nds on the q ual ity and
vis cos ity of the oil , the R PM (revo lutions per
m inute) a t which the engine is operated, the
ambient temperature and road conditions .
Further factors are the amount of oi l di lu­
tion from water condensat ion or fue l resi­
due and the oxidation level of the oil. As any
eng ine is subject to wear as m ileage builds
up, the oil consumption may increase over
t ime until replacement of worn components
may become necessa ry.
-With all these var iables com ing into play,
no sta ndard rate of o il consumption can be
established o r specified. There is no a lter na­
ti ve to c hec king the oil leve l reg ularly and
frequently.
-If you have the impress ion your e ngine co n­
sumes excessive amo unts o f oil, we recom ­
mend that you consult an author ized Audi
dea ler to have the cause of your concern
properly diagnosed . Keep in mind that t he
acc urate measurement of o il cons umption
requires great care and may take some
time . An authorized Aud i dealer has instruc­
tions about how to measu re o il consump­
tion accurate ly.

cle where temperatures remain below freezing
for extended periods.
Detergent additives in the oil will make fresh oil
l ook dark after the engine has been running for a
short time. This is norma l and is not a reason to
change the oil more often than recommended.
Because of the problem of proper disposa l, along
with the special tools and necessary expertise re­
quired, we strong ly recommend that you have
your oil changed by an authorized
Audi dealer or
a qualified service station .
If you choose to change your oil yourself, please
note the following important information:
A WARNING
To reduce the risk of personal injury if you
must change the engine oil in your veh icle
yourself:
- Wear eye protection.
- To reduce the risk of burns from hot engine
o il, let the eng ine cool down to the touch.
-
-When removing the oil drain plug with your
fingers, stay as far away as possible. Always
keep your forearm parallel to the ground to
help prevent hot oil from running down your
arm.
- Drain 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 well out of
the reach of children.
- Cont inuous contact w ith used engine oil is
harmful to your sk in. Always protect your
sk in by washing oil off thoroughly w ith soap
and water.
@ Note
Never mix oil addit ives with your engine o il.
These additives can damage your eng ine and
adversely affect your Audi Limited New Vehi­
cle Warranty.
Checking and Filling
@) For the sake of the environment
-Before changing your oi l, first make sure
you know where you can properly dispose of
the used oil.
- Always dispose of used engine oi l properly.
Do not dump it on garden soil, wooded
areas, into open streams or down sewage
drains.
- Recycle used engine o il by tak ing it to a used
eng ine oil collection fac ility in your area, or
contact a service station .
Cooling system
Coolant
The engine cooling system is filled wit h a mixture
of purified water and coolant additive at the fac ­
tory. This coolant must not be not changed.
T he coolant level is monitored through
the . in­
dicator light
r=:>poge 13. However, we do recom­
mend occasionally checking the coolant leve l
manua lly.
If you must add coolant, use a mixture of water
and coolant additive. Mixing the coo lant additive
with distilled water is recommended.
Coolant additive
The coolant additive is made of anti-freezing and
corrosion protection agents. Only use the follow­
ing coolant additives. These additives may be
mixed with each other .
Coolant additive Specification
Gl2evo
TL 774 L
Gl2++ TL 774 G
Gl3 TL 774
J
The amount of coolant additive that needs to be
mixed with water depends on the climate where
the vehicle wi ll be operated .
If the coolant addi ­
tive percentage is too low, the coolant can freeze
and damage the engine.
