•
High temperatures, as from exposure to intense sunlight, intens ify
the corrosive effect particularly when humidity is high as well.
Under ce rtain circumstances ,
weekly washing may be necessary .
Under other conditions, a monthly washing and waxing may be
adequate.
After the winter, the
underside of the vehicle should be thoroughly
washed preferably in a professional car wash .
& WARNING
Always read and heed all WARNINGS and the information
=>
page 200 . •
Automatic car wash
The vehicle can be washed in almost any modern auto­
matic 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 design 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 oper­
ator immediately . If necessary, use a different car wash .
The power top does not require specia l precautions before passing
through a car wash.
However, the car must not be treated with hot
wax after the wash cycle!
The wax could adversely affect the power
top and even damage the fabric over a period of time.
The power top do es not have to be washed every time you use a car
wash . The power top can be spared if the car wash facility is
equipped with manually adjustable roof brushes or rollers.
Before going through a car wash, be sure to take the usua l precau ­
tions such as closing the windows. Remove antenna if applicable . If
you have installed additional accessories on the vehicle -such as
spoilers, etc. -it is best to ask the car wash operator if these should
be removed.
& WARNING
Always read and heed all WARNINGS and the information
=> page 200. •
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 ::}
& in "General informa­
tion" on
page 200.
-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 persistent dirt .
- Rinse the car thoroughly with water.
- Use a chamois leather to gently wipe the exterior dry.
Use a separate sponge for cleaning the wheels, door si lls 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 . .,,

Natural leather
Aud i m akes gre at effo rts to maint ain th e pr oper ties,
n atur al look and feel of interi or le ather.
Gener al
We offe r many d ifferent types of leathe r on our vehicles. Mo st are
different types of nappa leather , which has a smooth surface and
comes in various co lo rs.
The intensity o f the color determ ines the visua l characteristics and
appearance. If the surface of the leather has a typical natura l look,
then t he leather is a nappa lea ther that has bee n left in a re latively
natura l condition. This leather offers particu lar ly good comfort and
b reathes well. Fi ne veins, closed g ra ins, insect bites, skin folds, an d
subtle variations in co lor remain visib le. These characteristics
dem onstrate that the mater ial is natural.
Natura l nappa leather is not covered by a co lor finish . It is therefore
more sensitive to soil ing and wear, which is something you need to
consider if chi ldren, animals or other fac tors might prove to be
particularly hard on the leather.
By con trast, leather types that are covered by a colo red fin ish layer
are more durable. This has a positive effect on the leather's resis ­
tance to wea r and s oiling i n daily use . On the ot her hand, the typical
characteristics of natura l leather are barely or not apparent .
However, this does not mean that the leather itself is of inferior
qua lity .
Care and handling
Because of the exclusive nature of the types of leather that Audi
u ses and thei r unique p rope rties (suc h as sens it ivity to oi ls, g rease,
soi ling, etc .), you wi ll need to be somewhat careful w ith these
leathers, and a certain type of care is required. For example, dark .,.

Never mix oil additives with your engine oil. These additives can
damage your engine and adversely affect your Audi Limited New
Vehicle Warranty .
W For the sake of th e environm ent
• Before changing your oi l, first make sure you know where you
can properly dispose of the used oil.
• Always dispose of used engine oil properly. Do not dump it on
garden soil, wooded areas, into open streams or down sewage
drains .
• Recycle used engine oi l by taking it to a used engine oil collec ­
tion fac ility 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 protects the engine from
freez ing in the winter.
The coo ling system is sealed and generally requires little attention.
T he coo ling system has been filled at the factory with a permanent
coolant which does not need to be cha nged . The coolant consists of
a mixture of water and the manufacturer's glycol-basedcoolant
addit ive G 12 + antifreeze with an ticorrosi on addit ives (50% for USA
models; 60% for Canadian models). This mixture both assures the
necessary frost protection and protects metal components in the
engine's cooling system from corrosion and scaling . It a lso raises
the boiling point of the coo lant .
Do not reduce t he concentration of the coolant in the summer by
adding plain water.
The prop ort ion of coolant additi ve mu st be at le
as t 50 % but not more th an 60 %
to maintain antifreeze protection
and co oling effic iency . If the coo lant fros t protect ion is too low, the
coolant could freeze and damage the vehic le heating and engine
coo ling system.
For year-round driving, antifreeze is added at the factory for temper ­
atures down to:
• - 31 °F ( - 35 °C) USA
• -40 °F ( -40 °C) Canada.
You can mix the G12 + coo lant additive with other additives (f or
examp le G11 or G12l. Always check with your authorized Audi
dea ler .
& WARNING
Before you check anything in the engine compartment , alway s
read and heed all WARNIN GS
=:> & in "Working i n the engine
c ompartment " on
page 220.
0 Note
• Before winter sets in, have the coolant checked to see if the
coolant additive in your vehicle is sufficient to meet the climate
conditions . This is especia lly important if you live in a region where
the winter is extremely cold. If necessary, increase the proport ion o f
coo lant additive to 60%.
• When adding coolant additive to your coo ling system,
remember :
- We recommend using only coolant additive G12+ (check the
label) for your vehicle. This coolant additive is avai lable at autho ­
rized Audi dealers. Other types of antifreeze can significantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sea lant to your vehicle's
engine coolant. Adding radiator repair fluid may adverse ly affect the _.,

Unbalanced wheels must be rebalanced to avoid excessive wear on
steering, suspension and tires. A wheel must also be rebalanced
when a new tire is installed.
Incorrect wheel alignment
Incorr ect wheel alignment can cause excessive tire wear, impairing
the safety of the vehicle. If tires show excessive wear, have the
wheel alignment checked by an authorized Audi dealer or qualified
workshop.
All Wheel Drive
Vehicles with quattro ® must always have tires of the same size,
construction and tread type. For details see
=> page 191.
& WARNING
Sudden tire failure can lead to loss of control, a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators .
• Worn tires are a safety hazard, they do not grip well on wet
roads and increase your risk of "hydroplaning" and loss of control .
• Always keep chemicals that can cause tire damage, such as
grease, oil, gasoline and brake fluid away from tires .
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds . Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •
New tires and replacing tires and wheels
New tires and wheels have to be broken in.
