the catalytic converter to overheat.
- Do not turn off the ignition while the ve ­
hicle is moving .
- Do not continue to operate yo ur vehicle
under these conditions, as otherwise fuel
can reach the cata lytic converter. This
could result in overheating of the con­
verter, requ iring its replacement.
- To assure efficient operation of the Emis­
sion Control System:
- Have your veh icle ma inta ined properly
and in acco rdance with the service rec­
ommendations in your Warranty
&
Ma intenance booklet.
- Lac k of proper maintenance as well as
improper use of the vehicle will impa ir
t he funct ion of the emission control

@ For the sake of the environment
Even when the Emission Contro l System is
operating p roperly, the exhaust gas can
have a s ulfu r- like exhaust gas smell under
some operating states. This depends on
the s ulfur content of the fue l being used.
Using a different brand of fuel may help,
or filling the tank w ith lead-free super
grade gasoline .
Operate your vehicle
economically and
minimize pollution
General
Your personal style of driving will determine
the economy of your vehicle, as well as ex­
haust and noise levels .
Fuel economy, environmental impact, and
wear on your engine, brakes and t ires largely
depend on three factors :
- your personal driving style
- operating conditions
- technical lim itations
I f you anticipate what you need to do nex t and
d rive economically, you can eas ily cut your
Dri vin g and en vironm ent 215
fuel consumption by 10 -15 percent. Th is sec ­
tion w ill give you some tips on how you can
help the env ironment and your pocketbook .
(D Tips
The cons umption estimates as published
by ENVIRONME NTAL PROTEC TION AGENCY
(EPA) and Transport Canada may not corre­
spond to your actual consumption on the road, which will vary depending upon vehi­
cle load and speed, road and weather con­
dit ions, trip length, etc.
Drive smoothly and keep a lookout
ahead
Vehicles use the most fuel when they are ac­
celerating.
.. Avo id unnecessary accelerating and brak ing .
Vehicles use the most fuel when they are ac­
ce lerat ing . If you ant icipate what is going to
happe n next, you will need to brake less and,
t hu s, accele rate less . Let the vehicle coast
whenever possible -for examp le when you see
that the next t raff ic light is red.
Avoid full throttle
Driving at moderate speeds saves fuel and
improves your mileage.
.. Try and keep well below your car's maxi -
mum speed .
Accelerat ing gently reduces fuel consump­
tion, eng ine wear, and does not disturb the
environment.
Fuel consumpt ion, exhaust emiss ions and en­
gine noise increase disproportionately at high
speeds. If you drive at approximately three
quarte rs of top speed, fuel consumption w ill
be reduced by one half. Never drive faster
t h an the posted speed limit and weathe r con­
ditions perm it.

216 Driving and environment
Reducing unnecessary idling
Even when your car is just idling it burns up
fuel.
.,. Shut the engine off when you are not driv­
ing the vehicle.
.,. Do not warm up the vehicle by letting the
engine run at idle .
It makes sense to shut off the engine in traffic
jams, when waiting for trains to pass at rail ­
road crossings, or at traff ic lights that have
l ong wa its on red. Turning the engine off for
just 30-40 seconds saves more fue l than is
burned starting the eng ine again .
It takes a long time for the engine to warm up
fully when it is running at idle. However , wear
and noxious emissions are especially high
when the engine is warming up. So you should
drive away as soon as you start the engine and
avoid running at high rpms while the engine is
still warming up .
(D Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
wou ld go unheeded. Extended idling also
produces heat, which cou ld result in over­
heating or other damage to the vehicle or
other property .
Regular maintenance
A badly tuned engine unnecessarily wastes a
lot of fuel .
... Have your vehicle serviced at regular inter-
vals.
By having your vehicle regularly serviced by an
authorized Audi dealer helps to ensure that it runs properly and economically . The condition
of your vehicle not only affects its safety and
ability to hold its value, it also affects
fuel
consumption .
Check your oil each time you fill your tank.
The amount of oi l used is re lated to engine
load and speed.
It is normal for the oil consumption of a new
engine to reach its lowest value after a certa in
mileage has been driven.
You must drive your veh icle about 3,000 m iles
(5,000 kilometers) before you can properly
assess oil consumpt ion.
This also app lies to fue l consumption and en­
gine output.
(D Note
- Have your veh icle ma inta ined properly
and in accordance with the service rec­
ommendations in your Warranty
& Main­
tenance booklet . Lack of proper mainte­
nance as well as improper use of the ve­
hicle will impair the function of the
emission contro l system and cou ld lead
to damage.
- Do not alter or remove any component of
the Emission Control System unless ap­
proved by the manufacturer.
- Do not alter or remove any device, such
as heat shields, switches, ignition wires,
valves, which are designed to protect
your vehicle's Emission Control System and other important vehicle compo­
nents.
Fewer short trips
Fuel consumption will always be relatively
high on short trips .
.,. Try to avoid driv ing short distances with a
cold engine .
The engine and cata lytic converter have to
reach their optimal
operating temperature to
reduce fuel consumpt ion and noxious emis­
s ions effectively .
Just after starting, a co ld engine in a mid-size
car only achieves a fuel economy of 6-8 mi les
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy cl imbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km), ll>

the engine is a t its proper ope rat ing tempera ­
ture and fue l economy has reached a no rma l
l eve l. So y ou can see that you sho uld avoid
short trips whenever poss ib le.
The
outside temperature is a lso critica l in this
regard. Yo ur car cons umes more fuel in the
winter than in t he summer .

Your authorized Audi dealer has a variety of
dedic ated veh icle-car e products and can ad ­
vise which ones to use for cleaning the exter i­
or and interior of your vehicle.
Whether you use products recommended by
Aud i or other commercially available clean ing
agents, please make sure you apply them cor­
rectly .
.&, WARNING
-Cleaning agents may be poisonous. Keep
them out of the reach of children.
- Heed all caut ion labels.
- Always read directions on the container
before using any product. Follow the di­
rect ions carefu lly.
- Most chemical cleaners are concentrated
and have to be diluted .
- Use spot removing fluids only in well
ventilated areas.
- Do not use gasoline, kerosene, d iesel
fuel, nail polish remover or other volatile
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ign it ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, e tc. w ithout pro­
tecting your hands and arms. You may c u t yourself on sharp -edged metal parts .
Cleaning and protec tion 221
- Moisture and ice on brakes may impair

information.
Test the brakes carefully
each time you wash the vehicle.
@) For the sake of the environment
Select on ly environmentally friend ly clean­
i ng products . Leftover cleaning products
should not d isposed of in the household
waste.
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental i n­
fluences is
frequent washing and waxing . How
often t his is required depends on:
- How much the veh icle is used
- Where the veh icle is parked (garage, in the
open under trees, etc.)
- The seasonal and weather conditions
- Environmental infl uences
T he longer b ird droppings, insects, tree resin,
road and indus tria l gr ime, ta r, soot, road salt
and other materials remain on the vehicle body, the more lasting their destructive ef­
fects wi ll be . High temperatures caused by ex­
posure to intense sun light intens ify the corro­
s ive effect, particularly when humid ity is high
as well.
Under certain circumstances,
weekl y washing
may be necessary. Under other cond itions, a
monthly washing and waxing may be ade­
quate .
After the winter, the underside of the vehicle
should be thoroughly washed, preferab ly in a
professional car wash .

222 Cleaning and protection
Automatic car wash
The vehicle can be washed in almost any
modern automatic car wash.
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash. However, the effect on
the paint depends to a large extent on the de­
sign of the facility, the filtering of the wash
water, the type of wash and care material, etc. If the paint has a dull appearance after going
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a car wash, be sure to
take the usual precautions such as closing the
windows and the roof. Factory installed an­
tennas must not be removed.
If you have installed additional accessories on
the vehicle - such as spoilers, roof rack, etc. -
it is best to ask the car wash operator if these
should be removed.
A WARNING
Always read and heed all WARNINGS and
other information
c;, page 221.
Washing the vehicle by hand
A lot of water is needed when washing a vehi­cle by hand.
., Before you start washing, make sure you
have read and understood the WARNINGS
r:::;, A in General information on page 221.
., First soak all dried dirt until it is soft, then
rinse it off.
., As you clean your vehicle, start with the
roof and work your way down to the bottom,
using a sponge, a sponge glove or a clean
brush.
., Rinse the sponge or the sponge glove often,
flushing it clean each time.
., Use special car shampoo only for very per­
sistent dirt.
., Rinse the car thoroughly with water .
., Use a chamois leather to gently wipe the ex­
terior dry. Use
a separate sponge for cleaning the
wheels, door sills and other regions exposed
to road dirt. In this way, you will not scratch
the paint with coarse particles imbedded in
the sponge the next time you wash the car.
A WARNING
---Do not clean the underside of the chas­
sis, fenders, wheel covers, or other hard
to reach parts without protecting your
hands and arms. You may cut yourself on
sharp-edged metal parts.
- Always read and heed all WARNINGS and
other information
c;, page 221.
0 Note
- Never try to remove dirt, mud or dust if
the surface of the vehicle is dry. Never
use a dry cloth or sponge, since this
could scratch your vehicle's paint or win­
dows.
- Never wash your car in bright sunlight.
Drops of water act as magnifying lenses
and may damage your paint.
-When you wash your car in the winter: if
you rinse your vehicle with a hose, be
careful not to aim the stream of water
directly at locks, or at door or hatch
openings - they can freeze shut.
- Never use sponges designed to remove
insects, or any kitchen scouring sponges
or similar products. They can damage
your paint finish .
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
ing your vehicle. Never use a dry cloth or
sponge to clean the headlights. Only use
wet cloths or sponges to prevent
scratches. It is best to use soapy water.
@ For the sake of the environment
In the interest of the environment, the ve­
hicle should only be washed in special
wash bays .

If the engine compartment is cleaned at any
time with grease removing solutions
1>, or if
you have the engine washed, the anti-corro­
sion treatment is almost always removed as
well. It is therefore essential to have a long­
lasting corrosion protection reapplied to all
surfaces , seams, joints and components in the
engine compartment .
.8, WARNING
Be aware: The engine compa rtment of any
motor vehicle is a potentially hazardous
area .
- Before working in the engine compart­
ment, be s ure to read the informat ion
~ page 237 .
-Before reaching into the front plenum
pane l, always remove the ignition key .
Otherwise, the windshield wiper system
cou ld unintentiona lly be switched on,
poss ibly causing personal injury from the
moving wiper linkage.
- Never reach into the area around or
touch the radiator fan. The auxiliary fan
is temperature controlled and can switch
on suddenly- even when the ign it ion is
off .
- Do not wash, wax or dry the engine w ith
the engine running . Moving or hot parts
could inju re you .
- Do not clean the underside of the chas­
sis, fenders, wheel covers, or other hard
to reach parts w ithout protecting your
hands and arms. You may cut yourse lf on
s harp-edged metal parts .
- Always read and heed all WARN INGS and

Blended gasoline
Use of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded g asoline blende d with
alcohol o r MTBE (commonly re ferred to as
oxygenates) if the blende d mixture meets t he
f o llow ing criteria:
Blend of gasoline methanol (wood alcohol or
methyl alcohol)
- Anti -kno ck index mus t be 87 A KI or higher.
- Blend must contain no mor e than 3% me th-
anol.
- Blend must contain more than 2% co-sol-
ve nts .
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti -knoc k index must be 87 AKI or higher .
- Blend must not conta in mo re than 10%
ethanol.
Blend of ga soline and MTBE
- Anti-knoc k index must be 87 AKI or high er. ll-

-Blend must contain not more than 15%
MTBE.
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
espec ially we ll for winter or summer driving.
During seasonal change-over, we suggest that
you fill up at busy gas stat ions where the sea­
sonal adjustment is more likely to be made in
time .
(D Note
-Methanol fuels which do not meet these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system .
- Do not use fue ls that fail to meet the
specified criter ia in this chapter.
- If you are unable to determine whether
or not a particular fue l blend meets the
specifications, ask your service station or
its fuel supp lier.
- Do not use fuel for which the contents
cannot be identified.
- Fuel system damage and performance
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 driveability and performance prob­ l ems due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Gasoline additives
A major concern among many auto manufac­
turers is carbon deposit build- up caused by
the type of gasoline you use.
Although gasoline grades differ from one manufacturer to another , they have certain
things in common. All gasoline grades contain
substances that can cause deposits to collect
on vital engine parts, such as fuel injectors
and intake valves. Although most gasoline brands include additives to keep engine and
