CA RE-------------------------
If the engine compartment is cleaned at any
time with grease removing solutions 1 ), or if
you have the engine washed, the antK:orr<r
sion treatment is almost always removed
as well. It is therefore essential to ask: for a
long-lasting corrosion protection of all sur­
faces, seams, joints and components in the
engine compartment.
c£> If you must rinse off gasoline, oil
residue or grease while you are
washing your engine, then tha dirty
water should be run through an oil
separator filter. We recommend that
you have your engine washed at a
qualified workshop or service sta­
ti on.
11 Use only
the correct cleaning solutions.
Never use gasoline or Diesel.
220 Chassis
The lower body shell of your Audi is also
thoroughly protected against corrosion.
Any damage to the undercoat ing caused by
road hazards should be repaired promptly.
g WARNING
Do not apply additional undercoat­
ing or rustproofing on or near the
exhaust manifold, exhaust pipes.
catalytic converter or heat shields.
During driving, the substance
used for undercoating could over­
heat and cause a fire. Body
cavity sealing
All body cavities which could be affected by
corro sion have been given thorough protec­
tion at the factory.
This sealing does not require any inspection
or additional treatments. If any wax should
seep out of the cavity when the ambient
temperature is high, it can be removed with
a plastic scraper and a suitable solvent.
c£> If you use benzine for removing
the wax, keep sparks, flame and
ligh ted cigara ttas away. Nsver
dump benzine on the ground, into
open streams or down sewage
dr ains.
Be sure to observe all safety and en­
vi ronmental regulations.

General
notes
• We recommend that you have the engine
compartment and the underside of your ve­
hicle inspected twice a year for any damage
to the protective coating, preferably before
and after the winter season. Have neces­
sary repairs done as soon as possible.
• Also, whenever the lower body sh�ll.
axle, transmission or engine assemblies
have been repaired, any anti-corrosion coat­
ing lost on the affected surfaces should be
reapplied.
• Oil-based protective sprays must not be
applied. Only tar-or wax -based anti-corro­
sion protectors are compatible with the fac­
tory applied corrosion pro tection. Bef_ore ap­
plication, road dirt, salt spray deposits and
oily substances must be removed. Yo
ur authorized Audi Dealer stocks the
cleaning and preservation solutions recom­
mended by the factory for this purpose and
has the equipment necessary to apply
them. Therefore, any additional corrosion
protection work should be perform .ed by an
Audi Dealer. Using incorrect cleamng solu­
tions could damage rubber parts or painted
surfaces.
� WARNING
Use only the correct cleaning solu­
tions. Never use gasoline, Diesel
fuel or solvents which could cause
a fire. VE

Fuel tank
The fuel filler neck is located on the right
rear side panel behind the fuel filler flap.
The central locking system automatically
locks and unlocks the fuel filler flap. If the
central locking system should fail, you can
still open the flap manually- see page 224
for further details.
Open the flap as illustrated above.
The capacity of the tank is:
approx. 18.5 US gallons (70 liters).
-222 When
refueling, hang the fuel tank cap on
the fuel filler flap as illus trated above.
Notes
• Don&#39;t drive until the fuel tank is
completely empty. Gasoline could
get in the exhaust system and dam­
age the catalytic converter.
• If any fuel has spilled onto the car,
it should be removed immediately to
prevent damage the paintwork. �W
ARNING
Under normal operating condi­
tions, never carry additional fuel
containers in your car. Such con­
tainers, full or empty, may leak
and could cause a fire in a colli­
sion. If you must transport fuel to
use for your lawn mower, snow
blower, etc., be very careful and al­
ways observe local and state laws
regarding the use, transportation
and storage of such fuel contain·
ers. Make certain the container
meets industry standards CANSII
ASTM F852-86).

Refu
elling the vehicle
Yo ur vehicle fuel tank has an on-board refu­
elling vapor recovery system. This feature
helps to prevent fuel vapors from escaping
from the tank and polluting the environment
while you refuel your vehicle.
In order to fill your tank properly while pro­
tecting the environment. please follow this
refueling procedure carefully:
• Turn off the engine.
• Remove the fuel filler cap by turning it
slowly counter clockwise allowing fuel
pressure to dissi pate.
• Insert the fuel nozzle from the gasoline
pump into the fuel filler neck as far as it will
go.
Select a medium refuelling rate, when filling
your tank. �W
ARNING
Failure to shut the engine off while
re fueling and I or to insert the
pump nozzle fully into the car&#39;s
filler neck could cause fuel over­
flow and fuel spray which can
cause fire or serious injury.
• Stop refueling when the fuel pump shuts
off automatical ly - do not add more fuel or
&#34;top off&#34;. dih As soon as the correctly oper­� ated nozzle switches off auto­
matically for the first time, the tank
is full. Do not try to add more fuel,
because fuel may spill out. In addi­
tion, the expansion space in the fuel
tank will be filled -causing the fuel
to overflow when it becomes warm
and pollute the environment.
• After filling your tank, turn the fuel filler
cap clockwise until you hear a definite click.
To avoid fuel spilling or evapor ating from the
fue I tank a I ways close fuel filler cap properly
and completely. VE
HICL E CA RE
Notes
• If you cannot fully insert the pump nozzle,
use another fuel pump or change gas sta­
tions.
• Do not refuel your vehicle with the igni­
tion switched on. The fuel gauge may other­
wise not indicate the exact fuel level after
refu elling.

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&#39;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
HICL E CA RE
Octane rating
Octane rating indicates a gasoline&#39;s ability
to resist engine damaging &#34;knock&#34; 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.

VEHICLE
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.

----------------------------------------------------VEHICLE
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&#39;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&#39;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
all scheduled maintenance and necessary
repairs. Your dealer has the facilities, origi­
nal parts and trained specialists to keep your
