Filling a portable fuel container
in excep tional cases
�W ARNING
To reduce the risk of fire and per­
sonal injury when filling a fuel con­
tainer for a lawn mower or snow
blower, etc. please remember:
• Never fill a portable fuel con­
tainer leaving It still in the luggage
compartment or on top of the car.
Static electricity can build up
while filling and can ignite fuel va­
pors causing a fire. Always place a
portable fuel container on the
ground before filling.
224 ��
WARNING continued
• Never spill fuel inside the lug­
gage compartment or vehicle inte­
rior. Fuel vapors are highly flam­
mable and can cause fire and seri­
ous bums.
• Always observe local and state
(provincaU laws regarding the use,
storage and transportation of such
containers. ·
• Make certain the fuel container
meets industry standards (ANSI/
ASTM F852-86). Emergency
unlocking of the
fuel filler flap
If the !?ower locking system should fail, you
can still open the flap manually:
o Open the rear lid.
• Remo ve cover from the right-hand trim
panel.
• To release the fuel filler flap, pull the ac­
tuator in the direction of arrow (see illustra­
tion).
• Open the fuel filler flap.

Fuel supply
..:lib Use only unleaded fuel in your
�v ehicle.
Fuel Recommendation
The fuel recommended for your ve­
hicle is unleaded premium grade
gasoline with a minimum octane rat­
ing of 91 AK PI/9 5 RON or higher.
The recommended gasoline octane rating
for your engine can also be found on a label
lo �ated on the inside of the fuel filler flap.
Th1s rat1ng may be specified as AKI or RON.
Yo ur vehicle may also be operated using un­
leaded regular gasoline with a minimum oc­
tane rating of 87 AKI /91 RON. However,
using 87 AKI I 91 RON octane fuel will lead
to a cert ain loss of engine power.
1l =(R+ Ml/2 Notes
• Do not usa any fuel with octane
ratings lower than 87 AKI or 91 RON
otherwise expansive engine damage
will occur.
• Do not use leaded gasoline!
The use of leaded gasoline will se­
verely damage your vehicle's cata­
lytic converter and its ability to con­
trol exhaust emissions.
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 avail­
able. VE

Octane rating
Octane rating indicates a gasoline's ability
to resist engine damaging "knock" caused
by pre-ignition and detonation. Therefore
�uying the correct grade of gasol ine is ve r-{
Important to help prevent possible engine
damage and a loss of engine performance.
Gasolines most commonly used in the
Uni ted States and Canada have the follow­
ing octane ratings that can usually be found
on the filler pump:
Premium Grade: 91 - 96 AKI
Regular Grade: 87 -90 AKI
Explanation of the abbreviations:
AKI = Anti Knock Index =
(R+M) I 2 = (RON+MON) I 2
RON = Research Octane Number
MON = Motor Octane Number.

CARE-------------------------
Use of gasoline containing alcohol
or MTBE (methyl tertiary butyl
ether)
You may use unleaded gasoline blended
with alcohol or MTBE (commonly referred
to as oxygenates) if the blended mixture
meets the following criteria:
Blend of gasoline methanol (wood
alcohol or methyl alcohol)
Anti-knock index must be 87 AKI or
hig her.
Blend must contain no more than 3%
methanol.
- Blend must contain more than 2% CO­
solvents.
226 Note
Methanol
fuels which do not meet
these requirements may cause cor­
rosion and damage to plastic and
rubber components in the fuel sys-
tem. ·
Blend of gasoline and ethanol (grain
alcohol or ethyl alcohol)
Ant i-knock , index must be 87 AKI or
high er.
Blend must not contain more than 1 0%
ethanol.
Blend of gasoline and MTBE
- Anti-knock index must be 87 AKI or
hig her.
Blend must contain not more than 15%
MTBE. Notes
• Do not use fuels that fail to meet
the specified criteria in this chapter.
• If you are unable to dete rmine
whether or not a particular fuel
blend meets the specifications, ask
your service station or its fuel sup­
plier.
• Do not use fuel for which the con­
tents cannot be identified.
• Fuel system damage and perfor­
mance 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 drivea bility and perfor­
mance problems due to the use of
one of these fuel blends, we recom­
mend that you switch to unblended
fuel.

CARE
Seasonally adjusted gasoline
Many gasolines are blended to perform es­
pecially well for winter or summer driving.
During seasonal change-over , we suggest
that you fill up at busy gas stations where
the seasonal adjustment is more likely to be
made in time. Gasoline
additives
A major concern among many auto
manufacturers is carbon deposit build-up
caused by the type of gasoline you use.
Although gasolines differ from one
man ufacturer to another, they have certain
things in common. All gasolines contain
properties that can cause deposits to col­
lect on vital engine components, such as
fuel injectors and intake valves. Although
most gasoline brands include additives to
keep engine and fuel systems clean, they
are not equally effective.
After an extended period of using inade­
quate fuels, built-up carbon deposits can
rob your engine of peak performance. Note
Damage or malfunction due to poor
fuel quality is not covered by the
Audi New Vehicle Limited Warranty.

CARE---------------------------------------------------
Maintenance
Yo ur vehicle has been designed to help
keep maintenance requirements to a mini­
mum.
However. a certa in amount of regular main­
tenance is still necessary to assure your ve­
hic le's safety, economy and reliabili ty.
c£> By regularly maintaining your
vehicle, you help make sure that
emission standards are maintai ned,
thus minimizing adverse effects on
the envir onment.
For detailed vehicle maintenance consult
your Maintenance booklet.
Under difficult operating condi­
tions, for example at extremely low out­
side temperatures, in very dusty regions,
when towing a trailer very frequently, etc.,
some service work should be performed
between the intervals specified.
This applies particularly to:
• oil changes, and
• cleaning or replacing the air filter.
228 Important
considerations for
you and your vehicle:
The increasing use of electr onics, sophisti­
cated fuel injection and emission control
systems, and the generally increasing tech­
nical complexity of today's automobiles,
have steadily reduced the scope of mainte­
nance and repairs which can be carried out
by vehicle owners. Also, safety and en­
vironmental concerns place very strict
limi ts on the nature of repairs and adjust­
ments to engine and transmission parts
which an owner can perform . Main
tenance, adjustments and repairs usu­
ally require special tools, testing devices
and other equipment available to specially
trained workshop personnel in order to as­
sure proper performance, reliability and
safety of the vehicle and its many systems.
Impr oper maintenan ce, adjustments and
repairs can impair the operation and reliabil­
ity of your vehicle and even void your ve­
hicle warranty. Therefore, proof of servicing
in accordance with the maintenance
schedule may be a condition for upholding
a possible warranty claim made within the
warranty period.
Above all, operational safety can be ad­
versely affected, creating unnecessary
risks for you and your passengers.

---------------------------------------------------VEHICLE CARE
If in doubt about any servicing, nave 1t done
by your authorized Audi Dealer or any other
properly equipped and qualif ied workshop.
We strongly urge you_ to give your autho­
rized Audi Dealer the opportunity to perform
