208 Fuel supply and filling your fuel tank
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 stations where the sea­
sonal adjustment is more likely to be made in
time.
CD Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only be used in vehicles with flexible fuel en­
gines. Using high ethanol fuel in vehicles not equipped with flexible fuel 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 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.
Ethanol fuel (Bio -ethanol)
App lies to vehicles: with flexible fuel e ngi ne
You con 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 (8S% ethanol and
15% gasoline) or with un­
leaded gasoline (91 AKI/ROZ 95). The vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption will increase when us­
ing bio-ethanol fuels 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 bio-etha­
nol, a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures . This fuel evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru­
ment cluster display, drive with a warm en­
gine to reduce the oil level.
CD Note
- Never fill with methanol or with a higher
percentage of bio-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fuel system .
-If you use only E85, it is recommended
to fill the fuel tank completely with un­
leaded premium grade gasoline every
5,000 miles .
- If you experience starting, rough idle or
hesitation driveability problems, fill the
fuel tank completely with unleaded pre­ mium grade gasoline and drive it nor­
mally until the gasoline is used. See your
authorized Audi dealer if the problem
persists.
- Inform your authorized Audi dealer that
you are operating or have operated the
vehicle with E85.
- Read and follow the information and tips
about gasoline

Using the proper engine oil is important for
the functionality and service life of the en­
g ine. Your engine was factory -filled with a
h igh-quality oil which can usually be used
t h roughout the entire year.
Your Limited New Vehicle Warranty does not cover damage or ma lf u nctions due to
fa ilure to follow recommended mainte­
nance and use requirements as set forth in
the Audi Owner's Manual and Warranty
&
Ma intenance booklet .
- Use only a high quality eng ine oil that ex­
pressly complies w ith the Audi o il quality
sta ndard specified for your veh icle's e n­
gine . U sing any other oil can cause seri­
ous eng ine dam age.
- Do not m ix any l ubrica nts o r othe r addi­
tives into the eng ine oi l. Doing so can
ca use eng ine damage.
I f you need to add oil and there is no ne
availab le tha t mee ts the Audi o il qua lity
s t andard your engine requires, yo u may
add a tota l of no more than 0 .5 quart/ liter
of a high -quality "synthetic"oil t hat meets
the following specifications.
- Vehicles with gaso line engine: ACEA A3
or API S M with a viscosity grade of
SAE 0W-30, SAE SW-30 or SA E SW-40.
- For more information abo ut eng ine oil
that has been app roved for your vehicle,
please contact either your a uthori zed
Audi dealer or Audi Customer Relations

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
cooling of inte rnal engine components, all in-
~ ternal combustion eng ines consume a certai n ,....,
Checking and fillin g 215
amoun t of oil. Oil consumpt ion varies from
engine to engine and may change significantly
over the life of the engine . Typically, engines
with a spec ified break-in period (see
¢
page 193) consume more oil during the
break -in period than they consume after o il
consumption has stabilized .
U nder normal cond itions, the rate of oil con ­
sumption depends on the quality and viscos ity
of the oil, the RPM (revolutions per minute) at
which the engine is operated, the ambient
temperature and road conditions. Further fac­
tors are the amount of oil dilut ion from water
condensa tion or fue l resid ue an d the oxida­
t ion level of the o il. As any engine is subject to
wear as mi leage b uilds 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 consumption can be es ­
tablished or specified. There is no alternative
to regular and frequent check ing of the o il lev ­
el, see
Note .
If the yellow engine oil leve l warning symbo l
El in the instrument cl uster lights up, you
sho uld check the oil leve l as soon as possib le

(D Tips
- The oil pressure warning display. is
not an indicator of the oil level. Do not
rely on it. Instead, check the oil level in
your engine at regular intervals , pref­
erably ea ch time you r efuel, and alway s
before going on a long trip . .,.

216 Checking and filling
-If you have the impression your engine
consumes excessive amounts of oi l, we
recommend that you consult an author­
ized Audi dealer to have the cause of
your concern properly diagnosed. Keep in
mind that the accurate measurement of
oil consumption requires great care and
may take some time . An authorized Audi
dealer has instructions about how to
measure oil consumpt ion accurately.

258 Tires and wheels
Accordingly, when the low tire pressure tell­
tale illuminates, you should stop and check
your tires as soon as possible, and inf late
them to the proper pressure. Driving on a sig­ nificantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-in­
flation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han­
dling and stopp ing ability.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
er's responsib ility to ma inta in correct tire
pressu re, even if under- inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined with
the low tire pressure telltale . When the sys­
tem detects a malfunction, the te lltale will
f lash for approximately one minute and then
remain cont inuous ly illuminated. This se­
quence will continue upon subsequent vehicle
start-ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is illuminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended. TPMS
malfunctions may occur for a variety of rea­
sons, includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from functioning
p rop erly. Always check the TPM S malf unct ion
tellta le after replacing one o r more t ires or
wheels on your vehicle to ensure that the re­ p lacement or a lternate tires and wheels allow
the TPMS to continue to function properly. Tire pressure indicator appears
App lies to vehicles : wi th tire p ress ure mo nito rin g system
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction .
Fig. 194 Display: u nde rinfla tion warning
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
dividua l tires.
If the pressure decreases in one
or more t ires, this is indicated in the instru­
ment cluster with a
RI] war ning symbol and a
message¢
fig . 194 . The driver message in the
display goes out afte r 5 seconds . The driver
message can be displayed again by pressing
the
ISETI button. If o nly one tire is affec ted,
the display will ind icate its position.
The tire pressure monitoring system must be
reset via rad io or MMI* each time the pres­
sures are adjusted (e.g. when switching be­
tween partial and full load pressure) or after
changing or replacing a tire on your ve hicle
¢
page 259. The TPMS indicator only moni ­
tors the tire pressure that you have previous ly
stored. You can find the recommended tire
pressures for your vehicle on the label on driv­
er's side 8-pillar ¢
page 234.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure
warning if:
- the tire pressure in one or more tires is too
low,
- the tir e has structural damage,
- the tir e pressure was changed, wheels rotat-
ed or rep laced but the TPMS was not reset
