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.

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.

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

nal equipment battery. Specifications are
listed on the battery housing.
When installing the battery, make sure the
ignition and all electrical consumers are
switched off.
r.Gb. Because of the problem of �proper di
sposal of a battery, we
recommend that you have your au­
thorized Audi Dealer change the
battery for you. Batteries contain
sulfuric acid and lead and must al­
ways be disp osed of properly ob­
serving all environmental regula­
tions. Air
cleaner
A dir ty air cleaner element not only reduces
the engine output and increases fuel con­
sumption considerably but can also cause
premature engine wear.
Normally, it is not necessary to service the
air cleaner more often than recommended
in the Maintenance booklet. If the vehicle is
driven on very dusty roads, the air cleaner
must be serviced more frequently, even dai­
ly.
If your air cleaner element must be
changed mora frequently, we rec­
ommend that you have the air clean­
er serviced by your authorized Audi
Dealer or a qualified workshop.
The air cleaner element must never
be cleaned or soaked with gasoline,
cleaning solvents or oil.
