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
Fuel supply and filling your fuel tank 177
fuel systems clean, they are not equally effec ­
tive .
A udi recommends using TOP TIER Detergent
Gasoline. For more info rmation on TOP TIER
Detergent Gasoline, please go to the official
website (www.toptiergas.com).
After an extended period of using inadeq uate
fuels, built-up carbon deposits can rob yo ur
engine of peak performance.

Be especially careful whenever you work in
the engine compartment!
Wheneve r you must pe rform any wo rk in the
eng ine compartment, for e xample chec king
and filling the different fluids, ther e is a risk
of injury, burns and a ccident s. To prevent
p ers onal injury al ways obs erv e the following

A WARNING
To he lp avoid injury, before yo u check any­
thing under the hood:
- Sw itch off the engine .
- Remove the ignition key.

@ For the sake of the environment
- Before changing your oil, first make sure
you know where you can properly dispose of the used oil.
- Always dispose of used engine oil proper­
l y. Do not dump it on garden soi l, wood­
ed areas, into open streams or down
sewage drains.
- Recycle used engine oil by taking it to a
used engine oil collection facility in your
area, or contact a service station.
Engine cooling system
Coolant
The engine coolant performs two functions: it
keeps the engine from overheating and it pro­
tects the engine from freezing in the winter.
The cooling system is sea led and generally re­
qu ires little at tention.
The cooling system has been filled at the fac ­
tory with a permanent coolant which does not n eed to be changed. The coolant consists of a
mixture of wa ter and the man ufacturer's g ly ­
col-based coolan t addi tive Gl3 ant ifree ze
with ant icorrosion add itives (50% for USA
models; 60% for Canadian models) . This mix­
ture both assures the necessary frost protec ­
tion and protects metal components in the
engine's cooling system from corrosion and
scaling. It also raises the boiling po int of the
coolant.
Do not reduce the concentration of the coo l­
ant in the summer by adding plain water.
The
proportion of coolant add itive must be at
lea st 50°/4 but not more than 60°/4
to ma in­
tain antifreeze protection and cooling efficien­ cy. If the coolant frost pro tect io n is too low,
the coolant cou ld freeze and dam age the veh i­
cle heating and eng ine cooling system.
For year-round driving, antifreeze is added at
the facto ry for temperatures down to:
- -31°F( -35°C)USA
- -40 °F ( -40 °C) Canada.

A WARNING
Before you c heck anything in the engine
compartment, always read and heed all
W ARNI NGS~ &.
in Working in the engine
comportment on page 180.
(D Note
- Before winter sets in, have the coolant
checked to see if the coolant additive in
your v ehicle is sufficient to meet the cli­
mate conditions. This is especia lly impo r­
t an t if you live in a region where t he win­
t er is ex treme ly cold. If ne cessary, in­
cr ease t he p ro portion of coo lant add itive
to 60%.
- Whe n adding cool ant additive to yo ur
c ooling sys tem, remember:
- We recommend us ing on ly coolant ad­
d itive Gl2++ or Gl3 (check the labe l)
for your veh icle. This coolant additive is
ava ilable at autho rized Aud i dea le rs.
Othe r types of antifree ze can sig nifi­
cantly reduce cor ros io n protec tion. The
res ulting co rrosion can cause a loss of
coolant an d serio us en gine damage.
- Do not add any type of rad iator le ak seal­
ant to yo ur vehicle 's eng ine coolant .

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 . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that a ll-impo rtant contact between
you, your 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 safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
Avoiding damage I f you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one side, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the sid ewa ll, that po int in the direc­
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.
For more information
¢page 227.
A WARNING
-New tires or tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
be broken in . To reduce the risk of losing
control, a co llision and ser ious personal
in jur ies, d rive w ith special ca re fo r the
fi rst 350 m iles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fl ation, c rashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- T ires age even if they are not being used
an d can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.

-Never mount used tires on yo ur vehicle if
yo u are not sure of their "previous histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al­
ways stop as soon as it is safe to do so
and check the wheels and tires for dam­
age .
