HICLE OPERATION------------------------
The external conditions
in which you drive also affect your fuel con­
sumption.
The following conditions increase fuel con­
sumption:
• Heavy traffic, especially in large cities
with many traffic lights.
• Stop-and-go driving, especially short dis­
tances so that the engine never warms up
as it should.
• Driving in heavy, slow moving traffic in
low gear so that the engine speed is rela­
tively high when compared to the distance
driven.
� Plan your trips ahaad of time. Or­
� ganizs your trips to include sev­
sral errands and to avoid heavy traf­
fi c.
Of course, there are some conditions that
will affect fuel consumption that you can't
control.
For example, fuel consumption increases in
the winter or under difficult conditions (bad
roads, towing a trailer, etc.).
19 6 The
technical requirements
for optimum fuel consumption and eco­
nomy were ''built" intoyourvehicle. Special
attention was paid to the environment. To
reta in and make use of these characteris­
tics, please note the following points:
riJ Use only unleaded gasoline.
Leaded gasoline causes damage to the cat­
alytic converter and other components of
the emission system.
t:Gh Have your vehicle serviced by an
� Audi Dealar at the specified in­
tervals -see page 228 and your
Main tenance booklet.
Having your vehicle regularly serviced by an
Audi Dealer helps ensure that it runs prop­
erly and economical ly, that it does not dis­
turb the environment, and that it has a long
service life. t:Gh
Check
your tire pressure once a
W month.
Low tire pressure increases fuel consump­
tion and tire wear, and impair s vehicle han­
dling.
�W ARNING
Underinflation and overloading of
tires can lead to tire failure. Sud­
den failur e on the road could cause
a serious or fata l accident. See
page 253 for inflation informa­
tion.
� Do not carry unnecessary items
in the luggage compartment.
Particularly in city traffic where you must
often accelerate, weight influences fuel
consumption.

----------------------VEHICLE
OPERATION
,:lib Remove
supplementary roof
� rack components when not In
use.
At high road speeds, the increased air �e­
sistance caused by the cross bars also In­
creases fuel consumption.
,:lib Switch oH any electrical equip­
� ment when no longer needed.
The more electricity you consume, the
higher the fuel consumption.
,:lib Check your vehicle 's fuel co?­'l!�Sr sumption regularly. Keep a writ­
ten record or use the trip odometer .
Check your fuel consumption ea?h time you
refu el. By doing this, you can d1scov �r a �y
inc onsistencies which could result 1n In­
creased fuel consumption and have these
checked before other problems appear. •
Check your oil each time you fill
your tank
The amount of oil used is related to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a cer­
tain mileage has been driven.
You must drive your vehicle about 3,000
miles (5 000 kilome tres) before you can
properly assess oil consumption.
This also applies to fuel consumption and
engine output.
• The published ENVIRONME NTAL
PROTECTION AGENCY (EPA) and
Tr ansport Canada consumption esti­
mates may not correspond to your
actual consumption on the road.
which will vary depending upon ve­
hicle load and speed. road and
weather conditions. trip length. etc. The
catalytic converter is an efficient
"clean-up" device built into the exhaust
system of the vehicle. The catalyttc convert­
er burns many of the pollutants in the ex­
haust gas before they are released into the
atmosphere.
The exclusive use of unleaded fuel is
critically important fo.r the life of
the catalytic converter and proper
functioning of the engine - see
page 225.
The catalytic converter will be per­
manently damaged by:
• Exc eeding the correct engine oil
level - see page 236;
• Driving until the fuel tank be­
comes completely empty. The en­
gine could misfire. Unburned fuel
could also get into the exhaust sys­
tem and this could cause the catalyt­
ic converter to overheat;

HICL E OPER ATION ------------------------
• Tu rning off the ignition while the
vehicle is movin g-sea page 115 -or
• Other unusual operating condi­
tions.
Do not continue to operate your ve­
hicle under these conditions, as
otherwise fuel can reach the catalyt­
ic converter. This could result in
overheating of the converter, requir­
ing its replacement.
To assure eHiciant operation of the
Emission Control System:
• Have your vehicle maintained
properly and in accordance with the
service recommendations in your
Maintenance booklet.
Lack of proper maintenance as well
as improper usa of the vehicle will
impair the function of the emission
control system and could lead to
damage.
19 8 Cl
Do not alter or remove any com­
ponent of the Emission Control Sys­
ta.m unless approved by the
manufacturer.
• Do not alter or remove any device,
such as heat shields, switches, igni­
tion wires, valves, which are de­
signed to protect your vehicle 's
Emission Control System and other
important vehicle components.
Nota
Do not leave engine idling unat­
tended after starting. If warning
lights should come on to indicate
improper operation, they would go
unheeded. Extended idling also pro­
duces heat, which could result in
overheat ing or other damage to the
vehicle or other property. �W
ARNING
• Parking
Do not park or operate the vehicle
in areas where the hot exhaust sys­
tem may coma in contact with dry
grass, brush, fuel spill or other ma­
terial which can causa a fire.
• Undercoating
Do not apply additional undercoat­
ing or rustproofing on or near the
exhaust manifold, exhaust pipes,
cata lytic converter or heat shields.
During driving, the substance
used for undercoating could over­
heat and causa a fire.

Cleaning and protec tion
Any automobile is subjected to abuse from
indus trial fumes, corrosive road salt, aban­
doned lollipops, muddy dog feet, etc. A well
cared- for Audi can look like new many years
after purchase. Regular and correct care will
contribute to maintaining the beauty and
value of your Audi.
Furthermore. good care may be a
condition for upholding a warranty
claim should corrosion damage or
paint defects occur.
Yo ur Audi Dealer has a variety of vehicle­
care products and can advise you which
ones to use for cleaning the exterior and in­
terior of your vehicle.

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

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'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'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.
