Notes
• Do not wash the vehicle in direct sun­
light.
• If the vehicle is rinsed with a hose, do not
direct the water into the lock cylinders -
otherwise they may freeze up in the winter.
�W ARNING
• Do not wash, wax or dry the ve­
hicle with the engine running.
• Do not clean the underside of
chassis, fenders, wheel covers,
etc. without protecting your
hands and arms. You may cut your­
self on sharp-edged metal parts.
• Moisture and ice on brakes may
affect braking efficiency. Test the
brakes carefully after each vehicle
wash.
214 Washing
your vehicle with a power
washer
If you use a power washer, please note the
following:
• Always follow the operating instructions
for the power washer -especially for pres­
sure and spraying distance.
• Make sure that the jet on the spray hose
produces a "fan shape" spray. Do not use
a jet which sprays the water out in a direct
stream or one that has a rota ting jet.
• Water temperature should not exceed
140 °F (60 °C).
�W ARNING
Never wash tires with a jet that
sprays the water out in a direct
stream. This could invisibly dam­
age and weaken the tires, even if
they are sprayed from a relatively
long distance for a vary short
amount of time. Damaged and
weakened tires can fail and cause
accidents and personal injury. Headli
ghts
Do not clean your headlights with a dry
towel or sponge. They must be cleaned
with a moistened towel.
Never use a sponge designed for removing
dried-on insects, a kitchen scrubber or any
other similar product since the lens surface
can be damaged by scrat ching and scour­
ing.
When using high-pressure washing equip­
ment or steam-cl eaning units, never spray
the vehicle with the nozzle close the vehicle
surface and never aim the spray at the same
point for a relatively long period of time.
Polishing Please refer to the imp ortant information on
page 212.
Polish your vehicle only if the paint has lost
its shine and the gloss cannot be brought
back with wax. If the polish used doesn't
contain preservative compounds, the paint
must be waxed afterwards.
Do not treat matte- pain�ed and plas­
tic parts with polish or wax.

possibly causing personal injury
from the moving wiper linkage.
• Do not wash. wax or dry the en�
gine with the engine ru!'l'! ing. Mov­
ing or hot parts could 1n1ure you. ,Al
WARNING continued
e Do not clean the underside of
the chassis, fenders. wheel cov­
ers. or other hard to reach parts
without protecting your hands and
arms. You may cut yourself on
sharp-edged metal parts.
• Moisture and ice on brakes may
affect braking efficiency. Test the
brakes carefully after each vehicle
wash.
The engine compartment and transmission
have been corrosion protected at the facto­
ry.
Remove leaves from the plenum panel in
front of the windshield under the engine
hood. This prevents the water drain holes
from becoming blocked, and it prevents de­
bris from entering the vehicle interior
throug h the heating and ventilation ducts. Good
anti-corrosion treatment is very im­
porta nt, particularly in the winter. If the ve­
hicle is frequently driven on salted roads,
the entire engine compartment and plenum
panel should be thor oughly cleaned at the
end of winter and retreated to prevent salt
damage. At the same time, the underside of
the vehicle should be washed as well.
�W ARNING
Never touch the radiator fan. The
auxiliary electric fan can switch on
suddenly and injure you-
Always switch off the ignition be­
fore cleaning the engine _

VEHICL E
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 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

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'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
"top off". 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.
223

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
HICL E CA RE
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.

----------------------------------------------------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.

VEHICLE
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
all scheduled maintenance and necessary
repairs. Your dealer has the facilities, origi­
nal parts and trained specialists to keep your
vehicle running properly.
