VE
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.

Engine compartment
�W ARNING
• Before working in the engine
compartment. be sure to read the
information on page 232.
I) Before reaching into the front
plenum panel. always re!"ove the
ignition key. Otherw1se. the
windshield wiper system could
unin tentionally be switched on.
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 _

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.

CLE CARE
J'4 WARN ING continued
• If you must work underneath
the vehicle with the wheels on the
ground, always make sure the ve­
hicle is on level ground. that the
wheels are always securely
blocked and that the engine can­
not be started. Always remove the
ignition key before anyone gets
under the vehicle.
Always make sure the transmis­
sion selector lever (automatic
transmission) is in "P" (Park posi­
tion) and the hand brake is firmly
applied.
• Always be extremely careful
when working on the vehicle. Al­ways follow commonly accepted safety practices and general com­
mon sense. Never risk personal in­
jury.

Changing the engine settings
will adversely aHect emission
levels. This Is detrimental to the en­
vi ronment and increases fuel con­
sumption.
Always observe environmental reg­
ulations when disposing of old en­
gine oil. used brake fluid, dirty en­
gine coolant, spent batteries or
worn out tires.

Engine compartment
�W ARNING
To help avoid injury, before you
check anything under the hood:
• Switch off the engine. Remove
the ignition key.
• Set the parking brake fully.
Move the selector lever toP (Park).
• Always let the engine cool
down. Hot components will burn
skin on contact.
• Never spill fluids on hot engine
components. They can cause a
fire.
• Never touch the radiator fan.
The auxiliary electric fan can
switch on suddenly and injure you.

WARNING continued
• If work on the fuel system or the
electrical system is necessary:
- Always disconnect the battery.
Never smoke or work near heat­
ers or open flames. Fluids in the
engine compartment could start
a fire.
Keep an approved fire extin­
guisher immediately available.
• To avoid electrical shock and
personal injury while the engine is
running or being started, never
touch:
- Ignition cables
- Other components of the high
voltage electronic ignition system. M
WARNING continued
• If you must perform a check or
repair with the engine running:
First, fully apply the parking
brake, move selector lever to
P (Park).
Always use extreme caution to
prevent clothing, jewelry, or
long hair from getting caught in
the radiator fan, V-belts or other
moving parts, or from contact­
ing hot parts. Tie back hair be­
fore starting, and wear no cloth­
ing that will hang or droop into
the engine.

-------------------------VEHICL E CA RE
Do not disconnect the vehicle bat­
tery when the ignition is switched
on or when the engine is running.
Otherwise, you will damage elec­
tronic components in the electrical
system.
When working on the engine, pro­
tect the battery housing from ultra
violet (UV) rays by not parking the
vehicle in direct sunlight. Winter
operation
During the winter months, battery capacity
tends to decrease as temperatures drop.
More power is also consumed while start­
ing, and the headli ghts, rear window defog­
ger, etc., are used more often.
Av oid unne cessary power consumption,
particularly in city traffic or when trave:ling
only short distances. Let your authonzed
Audi Dealer check the capacity of the ve­
hicle battery before winter sets in. A well
charged battery will not only prevent start­
ing problems but will also last longer.
If your vehicle is left standing for
several weeks at extremely low tem­
peratures, the vehicle battery
should be removed and stored
where it will not freeze. This will
prevent it from being damaged. Location
of vehicle battery
g Always heed all WAR NINGS

The vehicle battery is located under a cover
in the plenum chamber at the back of the
engine compartment. To remove the cover,
press the straps (arrows ), swing up and re­
move.
