(0 Note
Do not leave engine idling unattended af­
ter starting . If warning lights should come
on to indicate improper operation, they
would go unheeded. Extended idling also
produces heat, which could 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 serv iced at regular inter-
vals.
By having your vehicle regularly serviced by an
author ized Audi dealer he lps to ensure that it
runs properly and economically. The condition
of your vehicle not only affects its safety and
ab il ity to hold its value, it also affects
fu el
con sump tion .
C heck your oil each time you fill your tank.
The amount of oil used is related to engine
l oad and speed.
I t is normal for the oil consumption o f a new
engine to reach its lowest val ue after a certain
mileage has been driven.
You mus t drive yo ur vehicle abo ut 3,000 miles
(5,000 kilometers) be fo re yo u can properly
assess oi l consumption.
This a lso applies to fuel consumption and en­
g ine output.
(]) Note
-Have yo ur vehicle maintai ned properly
and in accordance with the service re c­
ommendations in your War ran ty
& Mai n­
tenance bookle t. Lack of proper mainte ­
nance as well as imp roper use of the
ve­
hicle will impair the function of the
emission control system and could 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 shie lds, switches, ignition w ires,
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 w ith a
cold engine.
The engine and cata lytic converter have to
reach their opt imal
oper ating temperature to
reduce fuel consumpt ion and nox ious em is­
s ions effectively.
Just after starting, a co ld engine in a mid-size
car on ly achieves a fuel economy of 6-8 m iles
per gallon (30-40 l/100 km). After about a
half a mile, fuel economy climbs to 12 mpg
(20 l/100 km) . After about
2 .5 miles (4 km),
the engine is at its prope r operating tempera­
tu re and fuel economy has reached a normal
level. So you can see that yo u should avo id
short trips whenever poss ible.
T he
outside temperatur e is also cr it ical in t his
regard. Your car consumes more fue l in the
winter tha n in the s umme r.

Your author ized Audi dealer has a variety of
d ed ica ted vehicl e-ca re product s and can ad ­
vise which ones to use for cleaning the exter i­
or and inte rior of your vehicle .
Whether you use products recommended by
Aud i or other commercially ava ilable clean ing
agents, please make sure you apply them cor­
rectly .
A 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 pol ish remover or other volati le
fluids. They may be toxic, flammab le or
haza rdous in other ways. Do not wash,
wax or dry the vehicle with the ignit ion
on or the engine running.
- Do not clean the undersides of chassis,
fenders, wheel covers, etc. without pro­
tecting your hands and arms. You may
c u t yourself on sharp-edged metal parts . -
Moisture and ice on brakes may impair
brak ing eff ic iency
c::> page 181. Test the
brakes carefully each time you wash the
veh icle.
@ For the sake of the environment
Select on ly environ mentally friendly clean­
i ng products. Leftover cleaning products
should not d isposed of in the househo ld
waste .
Care of exterior
Washing
Frequent washing protects the vehicle .
The best protection against environmental in ­
fluences is
frequent washing and waxing . How
often this 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 seasona l 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 destr uctive ef­
fects wi ll be . High temperatures caused by ex­
pos ure 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, preferably in a professional car wash.

196 Cleaning and protection
-Never use sponges designed to remove
insects, or any kitchen scouring sponges
or similar products. They can damage
your paint finish .
- 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.
- 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
Only wash the vehicle in facilities specially
designed for that purpose. This will reduce
the risk of dirty water contaminated with
oil from entering the sewer system. In
some areas, washing vehicles outside of
these facilities is prohibited.
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you
observe a few simple rules.
.. Before using the power washer, make sure
you have read and understood the WARN­
INGS¢
A in General information on
page 194 .
• Always follow the operating instructions for
the power washer .
• Make sure that the jet on the spray hose
produces a "fan shaped spray".
• Do
not hold the spray nozzle too close to
soft materials.
Never use a power washer to clean the power
top itself.
Keep a distance from soft materials such as
rubber hoses or insulating material as well as
sensors and camera lenses. When cleaning the vehicle with a power wash­
er
always follow the operating instructions.
This applies particularly to the operating pres­
sure and the spraying distance. Do not point
the spr ay directly at the seals around the side
windows, around the doors, on the rear lid or on the power top . Likewise, do not point it di­
rectly at tires, rubber hoses, insulation mate­
rial or sensors
¢page 198. Hold the spray
nozzle at least 1.3 ft (0 .4 m) away from the
vehicle.
Do not use a high-pressure power washer to
remove snow and ice .
Do not use a jet which sprays water in a direct
stream or one that has a rotating jet.
Water temperature should not exceed 140 °F
(60 °().
A WARNING "'--
Never wash tires with a jet that sprays wa -
ter in a direct stream . This could cause in­
visible damage to the tires and weaken
them, even if the spray is from a relatively
long distance and for a short time. Dam­
aged and weakened tires can fail and cause
accidents and personal injury.
(D Note
- Never use a power washer to clean the
power top itself.
- To avoid damaging your vehicle, always
make sure that there is sufficient dis­
tance between the spray head and soft
materials like rubber hoses, plastic parts
and sound-deadening materials as well
as sensors and camera lenses. Never aim
the spray head at the same point for a
long time . This also applies to cleaning
headlights and painted bumpers. Re­
member: the closer the nozzle is to the
surface of the material , the greater the
stress on the material.

oline or d iese l fuel.
Cleaning and protec tion
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
A lw ays switch o ff the ign it ion before cle an ­
i ng the eng ine
c> ,& .
Plenum pan el
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 debris from enter ing
the vehicle interior through the heating and
vent ilat ion ducts.
Co rro sio n protect ion
The engine compartment and transmission
have been corrosion-protected at the factory.
Good anti -corrosion treatment is very impor­
tant, partic ularly in the winter.
If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and p lenum panel
should be thoroughly cleaned at the end of
winter and retreated to prevent salt damage.
At the same time, the underside of the vehicle
shou ld be washed as well.
If the engine compartment is cleaned at any
time with grease remov ing solutions
1> , or if
you have the engine washed, the anti-corro­
s ion treatment is almost always removed as
well.
It i s therefo re essentia l to have a long­
lasti ng cor rosion pro tect ion reapplied to all
surfaces, seams, joints and components in the
engine compartment .
A WARNING
Be aware: The engine compartment of any
motor vehicle is a potentially hazardous
area.
- Before work ing in the engine compart­
ment, be sure to read the information

Blended gasoline
U se of gasoline containing alcohol or
MTBE (methyl tertiary butyl ether)
You may use unleaded g asoline blende d with
a lcohol o r MTBE (commonly re fer red to as
oxygenates) if the blende d mixture meets the
fo 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% meth-
anol.
- Blend must co ntain more than 2% co-sol-
vents .
Blend of gasoline and ethanol (grain alcohol
or ethyl alcohol)
- Anti -knoc k index must be 87 A KI or higher.
- Blend must not conta in mo re tha n 10%
ethanol.
- Ve hicl es w ith flex ible f uel engine : blend

208 Fuel supply and filling your fuel tank
-Anti -knock index must be 87 AKI or higher.
- Blend must contain not more than 15%
MTBE .
Seasonally adjusted gasoline
Many gasoline grades are blended to perform
especially well 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.
CD Note
- Fuels containing a high percentage of
ethanol such as ESO and E85 may only
be used in vehicles with flex ible fuel en­
gines. Using high ethano l fuel in vehicles
not equipped with flexib le fue l eng ines
can cause severe engine damage.
- Methanol fuels which do not mee t these
requirements may cause corrosion and
damage to plastic and rubber compo­
nents in the fuel system.
- Do not use fuels that fail to meet the
specified criteria in this chapter.
- If you are unable to determine whether
or not a particular fuel blend meets the
specifications, ask your service station or
its fuel supplier.
- Do not use fuel for which the contents
cannot be identif ied.
- Fuel system damage and performance
problems resulting from the use of fuels
different from those specified are not
the respons ibility 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 driveab ility and performance prob­
le ms due to the use of one of these fuel
blends, we recommend that you switch
to unblended fuel.
Ethanol fuel (B io-ethanol)
App lies to veh icles : w ith flex ible fue l en g in e
You can recognize vehicles with a flexible fuel
engine by looking at the label on the inside of
the fuel filler flap.
Vehicles with flexible fuel engines may be op­
erated with bio -ethanol fuels such as E85
(85% ethanol and 15% gasoline) or with un­
leaded gasoline (91 AKI/ROZ 95) . The vehicle
may also be operated with a mixture of these
fuels.
Your fuel consumption w ill increase when us­
ing bio-ethanol fue ls due to the lower amount
of energy contained per unit volume in etha­
nol.
Warming up the flexible fuel engine in
low temperatures
Due to the chemical composition of b io-etha­
nol , a certain amount of fuel ends up in the
engine oil when driving short distances in very
low temperatures. This fue l evaporates again
when the engine is warmed up.
II Please warm up engine.
If the driver message appears in the instru­
ment cluster display, drive with a warm en­
gine to reduce the o il level.
CD Note
- Never fill with methanol o r with a higher
percentage of b io-ethanol than 85%
(E85). A higher percentage of bio-etha­
nol in the fuel can cause damage to the
engine or to the fue l system.
- If you use only E85, it is recommended
to fill the fuel tank complete ly with un­
leaded premium grade gaso line every
5,000 miles.
- If you experience starting, rough id le or
hesitation driveability problems, fill the
fue l tank comp letely with unleaded pre­
m ium grade gasoline and dr ive it nor­
mally until the gasoline is used. See your
authorized Audi dealer if the problem
persists .

-Inform your authorized Audi dealer that
you are operating or have operated the vehicle with E85.
- Read and follow the information and tips
about gasoline
¢ page 207.
(D Tips
It may take longer to start the engine
when the outside temperature is very cold.
If possible, use winterized fuel if tempera­
tures are below freezing.
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
fuel systems clean, they are not equally effec­
tive.
Aud i recommends using TOP TIER Detergent
Gasoline . For more information on TOP TIE R
Detergent Gasoline, please go to the official
website (www.toptiergas .com) .
After an extended pe riod of using inadequate
fuels, built-up carbon deposits can rob your
engine of peak performance.
(D Note
- Damage or malfunction due to poor fuel
quality is not covered by the Audi New
Vehicle Limited Warranty.
- Do not add aftermarket fuel addit ive
products to your fuel tank.

The labe l on the inside of the fuel fi ller flap
tells you the correct fuel for your veh icle. For
more information about fuel specifications,
see¢page207.
Your vehicle fuel tank has an on-board refuel­
ling vapor recovery system. This feature helps
to prevent fuel vapors from escaping from the
tank and polluting the environment while you
refue l your vehicle. In order to fi ll the tank
properly while protecting the environment,
please follow this refueling procedure careful­
ly.
A WARNING
Under normal operating conditions, never
carry addit ional fuel conta iners in your car .
Gas canisters and other containers used to
transport fuel can be dangerous. Such con­
tainers, full or empty, may leak and could
cause a fire in a collision. If you must
transport fuel to use for your lawn mower,
snow b lower, etc., be very careful and al­
ways observe loca l and state laws regard­
ing the use, transportation and storage of
such fuel containers. Make certain the con­
tainer meets industry standards (ANSI/
ASTM F852 -86) .
(D Note
Never drive your vehicle until the fuel tank
is completely empty. The irregular supply
of fuel can cause m isfiring . Gasoline could
enter the exhaust system and damage the
catalytic converter .
