-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
especially well for winter or summer driving. During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea
sonal adjustment is more likely to be made in
time.
(D Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in veh icles with flex ible fuel* en
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l* engines
can cause severe engine damage .
- 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
specifications, ask your service station or
its fuel supplier.
- 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 respons ibility of Audi and are not
covered under the New Veh icle or the
Emission Control System Warranties.
- If you experience a loss of fuel economy
or driveability and performance prob
l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Fuel supply and filling your fuel tank 223
Ethanol fuel (Bio-ethanol)
Applies to veh icles: w it h flex ible fue l en gin e
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flap .
Vehicles with flexible fuel engines may be op
erated with bio -ethanol fuels such as E85
(85% ethanol and 15% gasoline) or with un
leaded gasoline (91 AKI/ROZ 95) . T he vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption will increase when us
ing bio-ethanol fue ls due to the lower amount
of energy contained per unit volume in etha
nol.
Warming up the flexible fuel engine in
low temperatures
Due to the chemical composition of b io-etha
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in ve ry
low temperatures. This fuel evaporates again
when the engine is warmed up.
D Please warm up engine.
If the driver message appears in the instru
ment cluster disp lay, drive with a warm en
gine to reduce the oil level.
(D Note
- Never fill with methanol or with a higher
percentage of b io-ethanol than 85%
(E85). A h igher percentage of bio-etha
nol in the fuel can cause damage to the
engine or to the fue l system.
- If you use only E85, it is recommended
to fill the fue l tank complete ly w ith un
leaded premium grade gaso line every
5,000 miles.
- If you experience starting, rough id le or
hesitation driveability problems, fill the
fuel tank comp letely with unleaded pre
mium grade gasoline and dr ive it nor
mally until the gasoline is used. See your
authorized Audi dealer if the problem
pers ists.

coolant can be seen or heard before care
fully opening the hood.
- Keep children away from the engine com partment.
- Never spill fluids on hot engine compo
nents. They can cause a fire.
- Never touch the radiator fan. The auxili
ary electric fan is temperature controlled
and can switch on suddenly.
- Never open the coolant reservoir cap
when the engine is still warm. The cool
ant system is pressurized and hot cool ant could spray out .
- Protect your face, hands and arm from
steam or hot engine coolant by placing a
thick rag over the cap when you open the
coolant reservoir .
- Do not remove the engine cover under
any circumstances. This increases the
risk of burns.
- If work on the fuel system or the electri
cal system is necessary:
- Always disconnect the battery.
- Never smoke or work near heaters or
open flames. Fluids in the engine com
partment could start a fire.
- Keep an approved fire extinguisher im
mediately available.
- To avoid electrical shock and personal in
jury while the engine is running or being
started, never touch:
- Ignition cables
- Other components of the high voltage
electronic ignition system.
- If you must perform a check or repair
with the engine running: -
First, fully apply the parking brake,
move selector lever of automatic trans
mission to P (Park).
- Always use extreme caution to prevent
clothing, jewelry, or long hair from get
ting caught in the radiator fan, V-belts
or other moving parts, or from contact ing hot parts. Tie back hair before
starting, and do not wear clothing that
will hang or droop into the engine.

according to the m ileage (kilomete rs) and
time inte rva ls specified in yo ur vehicle's War
ranty
& Maintenance booklet. Do not exceed
these intervals -harmful deposits from old
engine oil can reduce engine performance and
can lead to expensive eng ine repairs.
Changing the o il at the recommended inter
va ls is so very important because the lubricat
ing properties of oi l decrease gradually during
norma l vehicle use . If you are not sure when
you have your oi l changed, ask your author
ized Audi Service Advisor.
Under some circ umstances the engine oi l
should even be changed more frequently .
Change o il more often if you drive mostly
short distances, operate the vehicle in dusty
areas or mostly under stop-and -go traffic con
d itions, or when you use your veh icle where
temperatures stay below freezing point for l ong periods.
Detergent addit ives in the o il w ill make fresh

· 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 prov ide effective lubrication and
cooling o f inte rna l engine components, all in
ternal combustion engines consume a certain
amount of oil. Oil consumpt ion varies from
engine to engine and may change sign ificantly
over the life of the engine. Typically, engines
with a spec ified break-in period (see
Q page 205) consume more oil during the
break-in pe riod than they consume after o il
consump tion has stabilized.
Under normal cond itions, the rate of oi l con
sumption depends on the quality and viscos ity
of the oil, the RP M (revolut ions per minute) at
which the engine is operated, the ambient
tempe rature a nd road conditions. Furt her fac
tors are the amount of oil dilut ion from wa ter
condensation or fue l residue and the oxida
tion level of the oi l. As any engine is subject to
wear as mi leage builds up, the oil consump
tion may increase over time until replacement
of worn components may become necessary.
With a ll these variab les coming into p lay, no
standard rate of oil consumpt ion can be es
tablished or spec ified. There is no alternative
to regular and frequent check ing of the o il lev
el, see
Not e.

Engine 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 and generally re
q ui res little attention .
The cooling system has been filled at the fac
tory with a pe rmanent coolant which does not
need to be changed. The coolant consists of a
mixture o f spec ia lly condi tioned water and the
manufacturer's glycol -basedcoolant addi -
tive G l3 antifreeze with anticorrosion addi
tives (50% for USA models ; 60% for Canadian
models). This mixture both assures the neces
sary frost protection and protects metal com
ponents in the engine's cooling system from
corrosion and scaling . It also raises the boil
i ng po int of the coo lant .
Do not red uce the concentration of the coo l
ant in the summer by adding plain water.
The
proportion of coolant add iti ve mu st be at
least 50 % but not more than 60 %
to main
tain antifreeze protection and cooling efficie n
cy.
If t he coolant frost protect io n is too low,
the coo lant cou ld freeze and damage the veh i
cle heating and engine cooling system. F
or year -ro und driving, antifreeze is added a t
the factory for temperatures down to :
- -31°F(-35° C)USA
- -40°F ( -40°C) Canada.
If you must add coolant, use a mixture of wa
ter and coolant additive . Mix ing the coo lant
additive with distilled water is recommended .

- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from tires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
