A WARNING
Damaged safety belts can break in a crash.
- Anything that might damage your safety
belts could mean that you and your pas
sengers would not be adequately pro
tected in an accident.
- Safety belt performance depends on cor
rect installation. Never remove belts
from the vehicle to clean them.
- Do not use chemical cleaning agents,
bleach or dyes. They have corrosive prop
erties which weaken the webbing.
- When cleaning your safety belts, inspect
them for damage . If you discover dam
age, see your authorized Audi dealer.
- Always read and heed all WARNINGS and
the information

Engine compartment
Be especially careful when cleaning the en
gine compartment.
Corrosion protection
The engine compartment and transmission
have been corrosion -protected at the factory .
Good anti-corrosion treatment is very impor
tant, particularly in the winter. If the vehicle
is frequently driven on salt treated roads, the
entire engine compartment and plenum 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
should be washed as well.
If the engine compartment is cleaned at any
time with grease removing solutions
1>, or if
l) Use only the correc t cleaning sol utio ns. Never use gas
oline or diesel fuel.
Cleaning and protection 169
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.
A WARNING
Be aware: The engine compartment of any
motor vehicle is a potentially hazardous
area.
- Before working in the engine compart
ment, be sure to read the information
<=? page 175.
-Before reaching into the front plenum
panel, always remove the ignition key.
Otherwise, the windshield wiper system
could unintentionally be switched on,
possibly causing persona l 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 ignition is
off.
- Do not wash, wax or dry the engine with
the engine running. Moving or hot parts
could injure you.
- 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

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

tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more information on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadequate
fuels, built-up carbon deposits can rob yo ur

-For your safety, we strongly recommend
that you do not travel with a portable
fuel container in your vehicle. The con
tainer, full or empty may leak and could
cause a fire , especially in a crash .
-If, under exceptional circumstances, you
must transport a portable fuel container,
please observe the following:
- Never fill a portable fuel container
while it is anywhere in or on the vehicle (for example, in the luggage compart
ment, or on the trunk) . Static electrici
t y can build up while filling and can ig
nite fuel vapors causing a fire .
- Always place a portable fuel container
on the ground before filling .
- Always keep the filler nozzle complete
ly inside the portable container before
and during filling.
- If filling a portable container made of
metal, the filler nozzle must always be
in contact with the container . This will
help prevent static electricity from dis
charging and cause a fire.
- Never spill fuel inside the vehicle or
luggage compartment. Fuel vapors are
highly flammable.
- Always observe local and state/provin
cial laws regarding the use, storage
and transportation of fuel containers
- Make certain the fuel container meets
industry standards (ANSI/ ASTM
F852-86).
(D Note
I f any fuel has spilled onto the car, it
should be removed immediately to prevent
damage to the paint.
@ For the sake of the environment
As soon as the correctly operated nozzle switches off automatically for the first
time, the tank is full . Do not try to add
more fuel because fuel may spill out. In
addition, the expansion space in the fuel
tank will be filled -causing the fuel to

a) Tips
- Running your engine while refueling may
cause vapors to escape or even fuel to
spill out of the tank. This would then
shut off the fuel nozzle before the tank
is full.
- Do not refuel your vehicle with the igni
tion switched on. The fuel gauge may
otherwise not indicate the correct fuel
level after refueling .

Engine cooling system
Coolant
The coolant provides cooling for the engine.
The percentage of the coolant additive deter
mines the freeze protection of the coolant in the winter.
The cooling system has been filled at the fac
tory with a permanent coo lant which does not
need to be changed. The coolant consists of a
mixture of water and the manufacturer's gly
col-based coolant additive Gl2++ ant ifreeze
with ant icor rosion add itives (SO% fo r USA
models; 60% for Canad ian models).
Checkin g and fillin g 181
Coolant additive
The percentage of the coo lant add itive de
pends on the climatic cond itions in wh ich the
vehicle is operated . If the percentage of
freeze protection i n the coo lant is too low, the
coolant can freeze, leading to a failure o f the
cooling and heating circuit.
T he percentage of coolant addit ive has al
ready been adjusted at the factory for the ve
hicle's climatic conditions.
T he m ix rat io for USA models is SO% wa ter
and SO% coolant addit ive, for Canadia n mod
els 40% water and 60% coolant additive. This
mixture both ass ures the necessary frost pro

General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . T ires are,
however, one of the most important parts of a
vehicle, particularly considering the compara
tively small patch of rubber on each tire that
assures that a ll- important contact between
you, you r vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safely han
d le, avoiding damage from road hazards and
r eg ularly inspect ing t ires for damage i nclud
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid s udden tire failure in
cluding tread separat ion and blowouts.
A voidin g damage
If yo u have to d rive over a curb or similar ob
stacle, drive very slow ly and as close as possi
b le at a right angle to the curb.
A lways keep chemicals incl ud ing grease, o il ,
gasoline and brake fluid off the t ires .
I nspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedde d in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . T his ensures you to
be ab le to mount them correctly when you re
i nstall them .
When removed, the whee ls or t ires should be
sto red in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on r ims, in a horizontal pos it ion if
they are mounted on rims .
