(D Note
-Methanol f uels which do not mee t these re­
quirements may ca use corrosion and dam­
age to plastic and rubber components in the
fuel system.
-Do not use fuels that fai l to meet the speci­
fied criteria in this chapter.
- If you are unable to determine whether or not a particular fuel blend meets the speci­
fications, ask your service station or its fuel
supplier.
-Do not use fuel for which the contents can­
not be identif ied.
-Fuel system damage and performance prob­
l ems resulting from the use of fue ls differ­
ent from those specified are not the respon­
s ibility of Audi and are not covered under
the New Veh icle or the Emiss ion Control
System Wa rrant ies.
-If you experience a loss of fue l economy or
driveability and performance problems due
to the use of one of these fuel b lends, we
recommend that you switch to unblended
fuel.
Gasoline additives
Applies to: vehicles with gasol ine engine
A majo r concern among many auto manufactur ­
ers is carbon deposit build-up caused by the type
of gasoline you use.
A lthough gasoline grades d iffer from one manu­
facturer to another, they have cer tain things in
common . A ll gasoline grades contain substances
that can cause deposits to collect on vita l engine
parts, such as fue l injectors and intake valves . Al ­
though most gasoline brands include additives to keep engine and fuel systems clean, they are not
equally effective.
Audi recommends using TOP TIER Detergent Gas­
oline. For more informat ion on TOP TIER Deter­
gent Gasoline, please go to the official website (www.toptiergas .com) .
Check ing and Filling
After an extended period o f using inadeq uate
fuels, bui lt-up ca rbon deposits can rob your en­
gine of peak performance.
(D Note
- Damage or malfunction d ue to poor f uel
quality is no t covered by the Audi New Veh i­
cle Lim ited Warranty .
- Do not add af termarket fuel addi tive prod­
u cts to your fue l tank.
Diesel fuel
Applies to: vehicles with diesel engine
Always use U LSD (Ult ra Low Sulfur Diesel) No. 2.
T he ULSD No. 2 meets the AS TM 0975.
D iesel fuel w ith concentrations of b iod iesel h igh­
er than 5
% such as Bl 1, B20 or B100 are st rict ly
prohib ited.
Service station fuel pumps are labeled with the
cor rect fuel i nformation for easy recogn ition by
the user. If the d iesel fue l pump is not labeled
as k t he station operator wha t fuel is being dis­
pensed before fill ing up your vehi cle.
U LSD No . 2 may not be ava ilable outside the USA
and Canada. Be su re to check befo re t raveling to
othe r countr ies.
ULSD No . 2 can become thicker in very cold tem­
peratures, and th is can impa ir the engine's start­
ing and runn ing . Depend ing o n the season, gas
stations provide ULS D No. 2 that flows be tte r in
cold te mpe ra tures so that you can conti nue ope r­
at ing your vehicle as usual.
(D Note
- Yo ur vehicle's diese l eng ine w as designed
so ley for use w ith ULS D No. 2. Therefo re,
never use gasoline, heating oil, other fuels
or flow improvers. These contain s ubstances
that will severely damage the fuel system
and the engine. Such damage will not be
covered by your New Vehicle Limited War­
ranty.

e ngin e oil from Audi Genui ne Part s
Using the proper engine oil is important for the
functionality and service life of the eng ine. Your
engine was factory -filled with a high-quality oil
which can usua lly be used throughout the entire
yea r.
Note
Your Limited New Vehicle Warranty does not
cover damage o r malfunctions due to failure
to follow recommended maintenance and use requirements as set fo rth in the Aud i Owner's
Manual and Warranty
& Maintenance booklet.
- Use only a high q ual ity eng ine oil that ex-
pressly complies with the Aud i oil q uality
standard specified for your vehi cle's engine .
Using any other oil can cause serious engine
damage .
- Do not mix any l ubricants o r other additives
into the engine oil. Doing so can cause en­
gine damage.
(D Tips
If you need to add oil and there is none availa ­
b le that meets the Audi oil quality standard
your eng ine requires, you may add a total of
no more than 0.5 qt (0.5 l) of a h igh-quality
"synthet ic" o il that meets the following speci­
fications .
- Vehicles with gasoline eng ine: ACEA A3 or
API SM with a viscosity grade of SAE OW-30,
SAE 5W -30 or SAE 5W-40 .
- Vehicles with d iesel eng ine : ACEA C3 or
API CF with a v iscosity grade of SAE OW-30
or SAE 5W -30 .

Engine oil consumption
The engin e in your v ehicl e dep ends on an ad e­
quat e amount of oil to lubricate and cool all of
its moving parts.
In order to provide effect ive lub rication and cool­
ing of inte rnal engine components, all inte rnal
combustion engines consume a certain amount
of oil. Oil consumption varies from eng ine to en­
gine and may change significantly over the life of
the engine. Typ ically, engines w ith a specified
break -in period (see
c> page 86) consume more
o il dur ing the break-in per iod than they consume
after oil consumption has stabilized .
Under normal cond itions, the rate of oil con­
sumption depends on the qua lity and viscos ity of
the oil, the RPM (revolutions per m inute) at
which the engine is operated, the amb ient tem­
perature and road condi tions. Further facto rs a re
the amo unt of oil di lution from water co ndensa­
tion or fue l resid ue a nd the oxidation level of the
oi l. As any engine is subject to wear as mileage
builds up, the oi l consumption may increase ove r
time unt il replacement of worn components may
become necessary.
With a ll these variab les coming into play, no
standard rate of oi l consumption can be estab­
lished or spec ified . There is no alternative to reg­
ular and frequent checking of the oi l level, see
Note .
If the y ellow engine oil leve l warning symbo l Bl
in the instrument cluster lights up, you should
check the o il level as soon as possible
c> page 334. Top off the o il at your earliest con­
venience

@ For the sa ke of the env ironment
- Oil should never enter the sewer system or
come into contact with the ground.
- Pay attention to legal requirements when
disposing of empty oil containers.
(D Tips
- The oil level indicator in the display is only
an informational disp lay. If the oil leve l is
too low, a minimum oil warning appears in
the instrument cluster. Add oil and close
the hood. The current oil level is displayed in the instrument cluster the next time the
ignition is switched on .
- The engine oil consumption may be up to
0.5 quart/600 miles (0.5 liter/1,000 km),
depend ing o n driving style and operating
cond itions. Consumption may be higher
during the first 3,000 miles (5,000 km). Be­
ca use of th is, the engine oil level m ust be
checked regularly.
It would be best to check
each time you ref uel your vehicle and before
l ong drives.
Changing the engine oil
We recommend that hove your oil changed by an
authorized Audi dealer or a qualified service sta­ tion .
Before you check anyth ing in the engine compart­
ment,
al ways r ead and h eed all WARNIN GS~ &
in Working in the engine compartment on
page 330.
The engine oil must be changed according to the
intervals specified in your Warranty
& Mainte­
nance booklet . This is very important because the
lubricating properties of oil diminish gradually
during normal vehicle use.
Under some circumstances the engine oi l should
be changed more frequently. Change oil more of­
ten if yo u drive mostly short distances, operate
the vehicle in dusty areas or under predominant ly
stop-and-go traffic condit ions, or have your vehi­
cle where temperatures remain below freezing
for extended periods .
Check ing and Filling
Detergent additives in the oi l will make fresh oil
look dark after the engine has been running for a
short time . This is normal and is not a reason to
change the oi l more often than recommended.
Because of the problem of proper disposal, along
with the specia l tools and necessary expertise re­
quired, we strongly recommend that you have
your o il changed by an authorized
Audi de aler or
a qual ified service stat ion.
If yo u choo se to ch ange your oil yo urself , please
note the following important information:
A WARNING "--
To reduce the risk of persona l injury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protection.
-
-To reduce the r isk of burns from hot engine
oil, let the engine cool down to the touch.
- When removing the oil drain plug w ith your
f ingers, 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 tota l amount of oil in your engine.
- Engine oil is poisonous. Keep it well out of
the reach of children.
- Continuous contact with used engine o il is
harmful to your skin. Always protect your
skin by washing oil off thoroughly with soap
and water .
«I) Note
Never mix oil additives with your engine oil.
These additives can damage your engine and
adversely affect yo ur Audi limited New Vehi­
cle Warranty .
@ For the sake of the environment
-Before chang ing your oil, first make sure
you know where you can properly d ispose of
the used oil.
- Always dispose of used engine o il properly .

areas, into open streams or down sewage
drains.
- Recycle used engine oil by taking it to a used
engine oil collection facility in your area, or
contact a service station .
Cooling system
Coolant
The engine cooling system is filled with a mixture
of pur ified water and coolant addit ive at the fa c­
tory . T his coolant must not be not changed.
The coolant leve l is monitored through
the . in­
d icator
light ~ page 30. Howeve r, we do recom­
mend occasionally check ing the coo lant level
manually.
I f you must add coolant , use a m ixt ure of water
a nd coolant addit ive. M ixing the coolant additive
with d istilled water is recommended .
Coolant additive
The coolant addit ive is made of anti-freez ing and
corros ion protection agents . Only use the fo llow­
ing coolant add it ives . These additives may be
mixed w ith each other.
