Fuel level
The display@ Q page 10, fig. 3 only works
when the ignition is sw itched on . When the
d isplay has reached the reserve mark, the bot­
tom LED wi ll turn red and the
tD indicator
light turns on

computer display.
F or the tank capac ity in yo ur vehicle , refer to
the Tec hnical Data
Q page 288.
CJ) Note
Never d rive until the tank is completely
empty. The irregular supp ly of fuel that re­
sults from that can cause the engine to
misfire. Uncombusted f uel will then enter
the exha ust system. This can cause over­
heating and damage to the catalytic con­
verter .
Coolant temperature indicator
In vehicles without a coolant temperature in­
d icator , an indicator l ight . will turn on
when the coolant temperature is too h igh
Q page 20. Refer to Q Q) .
The coolant temperature ind icator @
c::> page 10, fig . 3 only works when the ignition
is switched on . T o prevent engine damage, ob­
serve the fo llow ing notes about the tempe ra­
ture ranges.
Cold range
If only the LEDs at the bottom of the gauge
turn on, the engine has not reached operat ing
temperature yet . Avoid high engine speeds,
fu ll acce le rat ing and heavy engine loads.
Norm al range
The engine has reached its operating temper­
ature once the LEDs up to the center of the
gauge turn on under normal driving condi­
tions. The L EDs higher up may turn on if the
engine is under heavy load or the o uts ide tern- perature is h
igh. This is not a cause for con­
cern as long as th e . indicator light in the
display does not turn on.
Hot range
If the L EDs in the upper area of the disp lay
and the. indicator light in the instrument
cluster disp lay t urn on , the coo lant tempera ­
ture is too high
c::> page 20.
A WARNING
I-
- Always observe the warn ing in
c::> page 217, before opening the hood
and checking the engine coolant level.
- Never open the eng ine hood if you see or
hear steam, or if you see engine coo lant
dripping from the engine compartment.
You could burn yourse lf . Let the engine
coo l off f irst unti l yo u can no longe r see
or hea r steam or coolan t escap ing.
Q) Note
- In vehicles w ith a boost pressure indica­
to r*, this indicator replaces the tempe ra­
t ur e display. To promote a long engine
service life, avoiding h igh engine speeds,
full acceleration and he avy eng ine lo ads
during approximately the first 15 m i­
nutes when the engine is co ld is recom ­
mended. The amount of time until the
eng ine is warm depends on the outside
temperat ure. Check the engine oil tem­
perature* if necessary.
c::> page 32
- Add itiona l head lights and other compo­
nents in front of the air intake impairs
the cooling effect of t he coolant. This in­
creases the risk of the engine overheat­
ing during high outs ide temperatures
and heavy eng ine load.
- T he front spoiler also he lps to d istr ibute
cooling ai r correctly wh ile driving. If the
spoiler is damaged, the coo ling effect
w ill be imp aired and the risk of the en­
gine overhea ting will increase . See an au­
thorized Audi dealer or autho rized Audi

Many gasoline grades are blended to perform
especially well for winter or summer driving. During seasonal change-over, we suggest that
you fill up at busy gas stations where the sea­ sonal adjustment is more likely to be made in
time.
Q;) Note
- Methanol fuels which do not meet these requirements may cause corrosion and
damage to plastic and rubber compo­ nents in the fuel system .
- Do not use fuels that fail to meet the
specified criteria in this chapter .
- If you are unable to determine whether
or not a particular fuel blend meets the
specificat ions, ask your service station or
i ts fuel supp lier.
- Do not use fuel for which the contents cannot be identified.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the responsibility of Audi and are not
covered under the New Vehicle or the
Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob­
lems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build-up caused by
the type of gasoline you use .
Although gasoline grades differ from one manufacturer to another, they have certain
things in common. All gasoline grades contain substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline
brands include additives to keep engine and
M
N fuel systems clean, they are not equally effec-o
iii tive. ,...., \!) ..,.,

Checking and Filling 211
Audi recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas .com).
After an extended period of using inadequate
fuels, carbon deposit build-ups can rob your engine of peak performance.
CJ) Note
Damage or malfunction due to poor fuel
quality is not covered by the Audi New Ve­
hicle Limited Warranty.
Diesel fuel
App lies to vehicles : wit h diese l eng ine
Always use ULSD (Ultra Low Sulfur Diesel)
No. 2 . The ULSD No. 2 meets the ASTM D975.
Diesel fuel with concentrations of biodiesel
higher than 5
% such as B11, B2O or B1OO are
strictly prohibited.
Service station fuel pumps are labeled with
the correct fuel information for easy recogni­
tion by the user.
If the diesel fuel pump is not
labeled ask the station operator what fuel is
being dispensed before filling up your vehicle.
ULSD No. 2 may not be available outside the
USA and Canada. Be sure to check before trav­
eling to other countries.
ULSD No. 2 can become thicker in very cold
temperatures, and this can impair the en­
gine's starting and running. Depending on the
season, gas stations provide ULSD No . 2 that
flows better in cold temperatures so that you
can continue operating your vehicle as usual.
(D Note
- Your vehicle's diesel engine was de­
signed solely for use with ULSD No. 2.
Therefore, never use gasoline, heating
oil, other fuels or flow improvers. These
contain substances that will severely
damage the fuel system and the engine.
Such damage will not be covered by your
New Vehicle Limited Warranty.

@ Tips
- The oil pre ssure wa rning display. i s
not an indicator of the o il level. Do not
rely on it. Instead , chec k the oil le vel in
your engine at regular inter vals, pref ­
era bly each t ime you r efuel , and always
before going on a long trip .
-If you have the impression your engine
consumes excessive amounts of oi l, we
r ecommend that you consult an author­
iz ed Audi dealer to have the cause of
you r concern properly di ag nose d. Keep in
mind tha t the ac curate measuremen t of
oi l consumption requires great care and
may take some time. An authorized Audi
dealer has instructions about how to measure oil consumption accurately.

page 24.
The oil consumptio n of the engine may be up
to 1/2 q uart per 600 m iles (0.5 liter per
1,000 km), depend ing on d riving style and
cond it io ns. Consump tion may be higher du r­
ing the first 3,000 m iles (5,000 km) . Be ca u se
of this, the eng ine oi l level must be checked
regular ly . It would be best to check each time
you ref uel your vehicle and before long dr ives.

.&_ WARNING
- When add ing o il, do not le t oi l dr ip onto
hot engine components . There could be
risk of a fire .
- You must sec ure the cap on the oil filler
opening correctly so that oil does not
leak out onto the hot engine and exhaust
system when the engine is running, be­
cause this is a fire hazard.
- Always clean skin thoroughly if it comes
into contact w ith eng ine oil.
([) Note
- Applies to vehicles with gasoline en­
gines: The oil level cannot be above the
(!) range¢
page 223, fig. 161, because
th is can ca use damage to the cata lytic
converter or the engine. Contact your au­
thorized Audi dealer or qua lified repair
facil ity to have excess o il extracted if
necessary.
-Applies to vehicles with diesel engines: The oil level must not be in the
0 range
¢
page 223, fig. 162 -The oil must not
be extracted, because this can damage
the engine. Drive to an au thorized A udi
dealer or authorized A udi Service Facility
immediately.
- Do not mix any additiona l lubricants into
the engine o il. Damage cause by such ad­
ditives is not covered by the war ranty.
@) For the sake of the environment
- Oil should never enter the sewer system
or come into contact with the ground .
- Pay a tte ntion to leg al req uirements
when disposing of empty oil containers .
Changing the engine oil
We recommend that have your oil changed by
an authorized Audi dealer or a qualified serv­
ice station.
Before you check anyth ing in the engine com­
partment,
always read and h eed all WARN­
INGS
¢ page 217.
The engine oil must be changed according to
the interva ls specified in your Warranty
&
Maintenance booklet . This is very important
because the lubricat ing propert ies of o il di­
min ish g radually du ring normal vehicle use.
Under some circumstances the engine oil
should be changed more frequently. Change o il more often if you drive mostly short d is­
tances, operate the ve hicle in dusty a reas or
under p redo min ant ly stop-and-go traffic con­
di tions, or have yo ur vehicle where tempera­
tures remain below freezing for extended pe ­
riods .
De te rgent additives in the oil will make fresh
o il look dark after the engine has been run ­
ning for a sho rt time. This is normal and is not
a reason to change the oil more often than
recommended.
Beca use of the p roblem of proper disposal,
along wi th the specia l tools and necessary ex­
pertise req uired, we st rongly recommend that
you have your oil changed by an a uthorized
Audi deale r or a qualified service station.
If you choo se to chan ge your oil your self ,
please note the fo llowing important informa­
tion:
.&_ WARNING
To reduce the risk of personal in jury if you
must change the eng ine oil in your vehicle
yourself:
- Wear eye protect ion.
- To reduce the risk of burns from hot en-
g ine oi l, let the engine cool down to the
touch.
- When removing the o il drain p lug with
your fingers, stay as far away as possible. ..,

M N

Always keep your forearm parallel to the
ground to help prevent hot oil from run­
ning down your arm.
- Drain the oi l into a conta iner designed
for this p urpose, one large eno ugh to
hold at least the total amount of oil in
your engi ne.
- Engine oil is poisono us. Keep it well out
of the reach of c hildren .
- Cont inuo us contact with used engine oil
is harmful to your skin. Always protect
you r sk in by washing oil off thoroug hly
with soap and water .
(D Note
Never mix oil addit ives with your engine
oil. These additives can damage your en­
gine and adversely affect y our Aud i Limit­
ed New Vehicle Wa rra nty .
@ For the sake of the environment
- Before changing your oi l, f irst make sure
you know whe re you can proper ly dispose
of the used o il.
- Always d ispose of used engine oil proper­
l y. Do not dum p it o n ga rden so il, wood ­
ed a reas, into open streams or down
sewage dra ins.
- Recycle used engine o il by taking it to a
u se d engine oil collection facility in your
a rea, or contact a servi ce station .
Cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­
tects the engine from freezing in the winter.
The cooling system is sea led an d generally re ­
q uir es little attention.
The cooling system has been filled at the f ac­
tory with a pe rm anen t coo lan t which does no t
n eed to be changed. The coolant consists of a
mixture of specia lly conditioned water and the
manufacturer's glyco l-based coo lant add i-
tive Gl3 antifree ze with ant icorros ion addi-
Checking and Fillin g 225
tives (50% for USA mode ls; 60% fo r Canadian
models) . This mixture both ass ures the neces­
sary frost protection and protects metal com ­
ponents in the eng ine's cooling system from
corros io n and scaling. It also raises the bo il­
ing point of the coolant .
Do not reduce the concentration of the cool ­
ant in the s ummer by adding p lain water.
The
proportion of coolant additive must be at
least 50°/o but not more than 60 %
to main­
ta in antifreeze protect io n and cool ing eff ic ien­
cy . If the coo lant frost p rotection is too low ,
t he coo lan t could freeze and damage the vehi ­
cl e heating and engine cooling sys tem.
Fo r year- round drivi ng, a ntifreeze is added at
the factory fo r temperatures down to:
- -31 °F
< -3s0c) u sA
- -40°F ( - 40°C) Canada.
If you must ad d coo lant, use a mixture o f wa ­
te r and coolant additive. Mixing the coo lant
additive with dist illed water is recommended.
A WARNING
Before you chec k anything in the engine
compartment, always read and heed all
WARNI NGS
c:> page 217.
-
(D Note
- Before winter sets in, have the coo lant
checked to see if the coolant additive in
your vehicle is sufficient to meet the cli­ mate condit ions. This is especially impor­
t ant if you l ive i n a region where the win-
t er is extremely cold. If necessary, in-
c rea se t he p ropo rtion of coo lant add itive
t o 6 0% .
- Whe n ad d ing coolant addi tiv e to yo ur
c ooling sys te m , reme mbe r:
- We recommend using on ly coo lant ad­
d itive Gl2 ++ or Gl3 (check the labe l)
for your vehicle. This coolant additive is ava ila ble at autho rized Aud i dea le rs .
Othe r ty pes of antifreeze ca n sig nifi­
cantly reduce cor ros io n protec tion . The
r esu lting co rrosion can cause a lo ss of
