Placing your vehicle out
of service
If you wo uld like to take yo ur vehicle out of serv­
ice for a longer time, contact your authorized
Audi dealer or qualified repair facility . They will
advise you of important measures ., such as ..,.

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,
please go to the official website
(www.toptiergas.com).
The recommended gasoline octane rating for
your eng ine 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 AKl/91
RON octane fue l will s lightly reduce eng ine 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 unleaded gasoline may not be available.
For more informat ion on refueling your vehicle,
see
~page 192.
Octane rating
Octane rating ind icates a gasoline's ability to re­
sist engine damaging "knock" caused by prema­
ture ignition and detonation. Therefore, buying
the correct grade of gasoline is very important to
he lp prevent possible eng ine 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
190
Explanation of the abbreviations:
AKI= Anti Knock Index= (R+M)/2 = (RON+MON)/
2
RON = Re search Octane Number
MON= Motor Octane Number.
CJ) Note
- Do not use any fuel 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 a l­
cohol or MTBE (commonly referred to as oxygen­
ates) if the blended mixture mee ts the following
criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti-knock index must be 87 AKI or h igher .
- 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 h igher.
- Blend must not contain more than 1S% etha-
nol.
- Veh icles with flex ible fuel engine: 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-over, we suggest that you ""

Checking and F ill in g
Using the proper engine o il is important for the
functionality and service life of the engine. Your
engine was factory-fi lled w ith a high-quality o il
which can usually be used throughout the ent ire
year.
@) Note
Your L imited New Vehicle Warranty does not
cover damage or malfunctions due to failure
to follow recommended ma intenance and use
requ irements as set forth in the Audi Ow ne r's
Manual and Wa rranty
& Ma intenance booklet .
- Use only a high quality eng ine oil t hat ex-
pressly comp lies w ith the Audi o il quality
standard specified for your vehicle's e ngine .
Using a ny other oil can cause se rious engine
damage.
- Do not mix any lubricants o r othe r addit ives
i nto the engine oil. Doing so can cause en ­
g ine damage.
(D Tips
If you need to add oil and there is none availa­
ble that meets the Audi o il quality standard
y o ur eng ine requires, you m ay add a total of
no more than 0.5 quart/li ter o f a h igh-quali ty
"synthet ic"oil that meets the fo llowing speci ­
fications .
- V ehicles wi th gasoline engine: AC EA A3 o r

Engine 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
i n g of in ternal engine components, all interna l
combustion engines consume a certai n amount
of oil. O il consumption var ies from engine to en­
g ine and may change significant ly ove r the life of
198
the engine. Typically, eng ines with a specif ied
break-in period (see
¢ page 177) consume mo re
o il dur ing the b reak -in per iod than they consume
after oil consumption has stabili zed.
U nder normal cond itions , the rate of oi l con ­
s u mption depends on t he qu ality and viscosity of
the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient tem ­
perature and road condit ions. Further factors are
the amount of o il di lution from water condensa ­
tion or fuel residue and the ox idat ion level of the
o il. As any engine is s ubject to wear as mileage
builds up, t he oil consump tion may inc rease ove r
t ime unt il rep lacement of wo rn component s may
become necessary.
With a ll these va riab les coming into p lay, no
sta ndard ra te of oil consumpt ion can be estab­
li shed or spe cified . There i s no altern ative to reg­
u la r and freq uent checking o f the oil leve l, see
Note .
If the yellow e ngine oi l leve l wa rning symbo l El
in the instr ument cluster lights up, yo u should
chec k the o il level as soon as possible
¢ page 199 . Top off the oil at your ear liest con ­
venience ¢page 199.
A WARNING
Before you chec k anything in the eng ine com­
partment, always read and heed a ll WARN­
INGS¢ .&. in Working in the engine compart­
ment on page 195 .
@ Note
Driving with an insufficient oi l level is likely to
cause severe damage to the engine.
(D Tips
- The oil pressu re warning display. is not
an indicator of the oil level. Do not rely on
it . Instead, check the oil level in your en­
gine at regular intervals, preferably each
time you refuel, and always before going on a long trip.
- If you have the impression yo ur engine con­
sumes excessive amounts of oil, we r ecom-
mend that yo u consult an au tho rized Audi .,.

specially conditio ned water an d the manu fa ctu r­
er's glycol-basedcoolant additive Gl3 antifreeze
with anticorrosion additives (50% for USA mod­
els; 60% for Canadian models). This m ixture both
assures the necessary frost protection and pro­
tects meta l components in the engine's cooling
system from corrosion and scal ing . It also raises
the boiling point of the coolant.
Do not reduce the concentration of the coolant in
the summer by adding plain water .
The p ropor­
tion of coolant addit ive must be at l east 50 %
but n ot mor e th an 60 %
to maintain antifreeze
protection and cooling efficiency. If the coolant
frost protection is too low, the coolant cou ld
freeze and damage the vehicle heating and en­
gine cooling system.
F or yea r-round driving, antifreeze is added at the
factory fo r temperatures dow n to:
- -31°F(-35°C)USA
- -40 °F ( - 40 °C) Canada.
If you must add coo lant, use a mixture of water
and coolant addit ive. Mixing the coolant additive
with distilled water is recommended.
A WARNING
Before you check anything in the engine com­
partment, always read and heed all WARN­
INGS
¢ &. in Working in the engine compart­
ment on page 195.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant addit ive in your
vehicle is suffic ient to meet the cli mate con­
dit ions. This is especially important if you
li ve in a region where the win ter is extreme­
l y co ld. If ne cessary, i ncrease the proport ion
of coo lant add itive to 60%.
- When adding coolant a ddit ive to you r cool ­
i ng system, remember:
- We recommend using only coolant addi­
tive Gl2++ or Gl3 for your ve hicle. This
coolant additive is ava ilable at authorized
Audi dea lers. Other types of ant ifreeze can
significant ly reduce co rrosion protection.
Checking and Fillin g
The resulting corrosion can ca use a loss o f
coolant and serious engine damage.
- Do not add any type of rad iator le ak sealan t
to your vehicle's engine coolant. Adding ra­
diator repai r fluid may adverse ly affect the
function and performance of your cooling
system and could result in damage not cov­
ered by your New Vehicle Lim ited Warranty.
Checking the engine coolant level
The engine coolant level can be checked with a
quick glance.

blink until you add coo lant and the level has been
restored to normal. Even though there is an e lec­
tr ic coo lant level sensor, we still recommend you
check the coo lant level from t ime to time.
Coolant los s
Coolant loss may indicate a leak in t he cooling
system. In the event of coolant loss, the cooling
system should be inspected immediately by your
authorized Audi dealer. It is not enough merely
to add coolant.
I n a
s e a led system, losses can occur only if the
boiling point of the coo lant is exceeded as a re­
sult of overheating.
A WARNING
The cooling system is under pressure and can
get very hot. Reduce the risk of scalding from
hot coolant by following these steps .
- Turn off the engine and allow it to coo l
down .
- Protect your face, hands and arms from es­
caping fluid and steam by covering the cap
with a large, thick rag .
-Turn the cap slowly and very carefully in a
counter-clockw ise d irection while applying
light, downward pressure on the top of the
cap.
- To avoid being burned, do not spill ant i­
freeze or coolant on the exhaust system or hot eng ine parts . Under ce rtain conditions,
the ethy lene g lycol in engine coolant can
catch fire.
{il) Note
Do not add any type of rad iator leak sealant
to your veh icle's engine coolant . Adding radia­
to r repair f lu id may adverse ly affect the func­
tion and performance of your cooling system
and could resu lt in damage not covered by
