Waxing and Polishing
Wa xing
A good wax coating protects the vehicle paint
to a large extent against the environmental
factors listed under¢
page 204, Washing and
even against slig ht scratches.
You can use a liq uid ca r wax to protect your
paint as soon as one week after your vehicle
has been delivered.
Even if you regularly use a
wax ing process in
automatic ca r washes, we recommend that
you manua lly app ly a coat of wax to give the
pa int extra protection, particularly if water no
longer beads o n the clean paint.
Protect p lastic body pa rts with car wax in the
same way as the vehicle body.
D uring wa rm weather dead insec ts tend to
collect on the front bumper and on the for­
ward area of the hood . They are much easier
to remove from paint that is waxed
often.
P olish ing
P olish you r vehicle on ly if the pa int has lost its
shine and the g loss cannot be brought back
with wax.
If the po lish used does not conta in prese rva­
tive compounds , the paint must be waxed af­
terwa rds .

Natural leather
Appl ies to vehicles: with natural leather
Audi makes great efforts to maintain the
properties, natural look and feel of interior
leather .
General
We offe r ma ny d iffe rent types of leathe r o n
ou r vehicles. Most are diffe rent types of nappa
l eather, which has a smooth surface and
comes in various colo rs .
T he intensity of the co lor determ ines the visu­
al cha racteristics and appea ran ce. If the su r­
f a ce of the leather has a typ ica l na tural look,
then the leather is a nap pa lea ther that has
been left in a relative ly natura l condition . This
leather offers particularly good comfort and
breathes well. Fine veins, closed grains, insect
bites, sk in fo lds, and subt le variations in color
rema in v isible. These character istics demon­
strate that the mate rial is natural.
Natura l nappa leather is not covered by a co l­
or finish. It is therefore more sens it ive to soil­
ing and wear, which is someth ing you need to
conside r if ch ildren, animals or other factors
might prove to be part icu larly hard o n the
leat her .
By contrast, leather types that are covered by
a colo red finish layer are more durable. This
has a positive effect on the leather 's resist­
an ce to wea r and soiling in da ily use. On the
othe r hand, the typica l charac teristics of natu­
ral leathe r are barely or not appa ren t. Howev­
er, this does not mean that the leathe r itse lf
is of infe rior quality. •

212 Cleaning and protec tio n
Care and handling
Because of the exclusive nat ure of the types of
l eather that Audi uses and their unique prop ­
erties (such as sensitivity to oils, grease, soi l­
ing, etc.), you will need to be somewhat care­
fu l w ith these leathers, and a certain type of
care is required. For examp le, dark cloth ing
materials can d iscolor leather seats (especial­
ly if such cloth ing is damp and was not dyed
correctly). Dust and dirt part icles in pores,
folds, and seams can have an ab ras ive effect
and can damage the leather surface as well as
weaken seams.
The leather should be cleaned regularly as
needed. After having been used for a re latively
long t ime, your leather sea ts will acquire a
rich aged finish. This is a characteristic of nat­
ura l leather and a sign of true quality .
I n o rder to maintain the va lue of t his natura l
p rod uct over the life of your vehicle, you
should follow the recommendations below :
(D Note
-To keep you r leather from bleaching out,
do not a llow it to be exposed to bright
sunl ight for long periods of time. If you
have to leave the vehicle parked o utside
for long periods, cover the leather to
protect it from d irect exposure to sun­
li ght.
- Sharp objects on clothing, such as zip­
pers, rivets or sharp pieces on be lts can
l eave permanent scratches or scrape
marks on the surface of the leather.
- After each t ime you clean the leather and
at regu lar intervals, use a leather preser­
vat ive creme that conta ins UV-blockers
and that works into the leather. This
creme wi ll nourish and moistur ize the
l eather, helping it to b reath e and stay
supple.
It also helps to bu ild up a protec­
tive coat ing on the s urface.
- Clean t he leather every 2 -3 mont hs,
and clean a ny areas that get soiled. - Remove fresh marks made by ballpo
int
pens, ink, lipstick, shoe polish, etc. as
soon as poss ible.
- Preserve the color of the leather as need­
ed by using a specia l co lored leather care
creme to touch up areas of uneven color.
Cleaning and caring for leather
upholstery and trim
Applies to vehicles: with natural leather
Natural leather requires special care and a t­
tention .
Normal cl eaning

grease or oil -based spots
(such as butte r, mayonnaise, chocolate) with
an absorbent cloth or paper towel, or use
the cleaner from the leather care kit if the
spo t has no t yet penetrated i nto t he surface
of the leathe r .
.. Use an oil/grease d issolving spray, if
oil /
grea se spot s ha ve d ried on.
.. Remove specific k inds of spots (ballpoint
pen, fe lt marker, fingerna il polish, water­

214 Cleaning and protection
-When cleaning your safety belts, inspect
them for damage.
If you discover dam­
age, see your Audi dealer .
- Always read and heed all WARNINGS and
other information
c> page 204.
Engine compartment
Be especially careful when cleaning the en­
gine compartment.
Always switch off the ignition before clean­
ing the engine
c> .&..
Plenum panel
Remove leaves from the plenum pane l in front
of the windsh ield under the engine compart­
ment. This prevents the water dra in ho les
from becoming blocked, and it prevents de­
bris from entering the vehicle interior through
the heating and venti lation ducts .
Corrosion protection
The engine compartment and transmission
have been corrosion -protected at the factory.
Good ant i-corrosion treatment is very impor­
tant, particularly in the winter. If the veh icle
is frequent ly driven on salt treated roads , the
enti re engine compartment and plenum panel
should be tho roughly cleaned at the end of
winter and retreated to prevent sa lt damage.
At the same time, the underside of the vehicle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solutions
1l, or if
you have the engine washed, the anti-corro­ sion treatment is a lmost 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 .
1l Use o nly the co rrect cle anin g so lu ti on s. Ne ver use gas­
o lin e or d ie se l fuel.
A WARNING
Be aware: The eng ine compartment of any
motor vehicle is a potentially hazardous
area .
- Before work ing in the engine compart­
ment, be sure to read the information
c> page 220.
-Before reach ing into the front panel, al ­
ways sw itch off the ignition . Otherwise,
the windshield wiper system could unin­
tentionally be switched on, possibly
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 sw itch
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.

a reason to change the oi l more often than
recommended.
D am age or m alfunc tions du e to lack of
m ainten ance
It is essential that you change your oil at the recommended in tervals using only engine o il
that complies with Audi oi l standard
VW 502 00. You r Limited New Vehicle War­
ranty does not cover damage or malfunctions
due to fail ure to fo llow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty &
Maintenance book let . Your dealer will have to
deny warranty coverage unless you present to
the dea ler proof in the form of Service or Re­
pa ir Orders that all scheduled ma intenance
was performed in a t imely manner.
Eng ine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving parts.
In order to provide effective lubrication and
cool ing of internal engine components, a ll in­
ternal comb ustion eng ines consume a certa in
amount of oil. O il consumption varies from
engine to engine and may change significantly
over the life of the engine. Typica lly, engines
with a specif ied break-in period (see
¢
page 196) consume more oil during the
break-in period than they consume after oil
consumption has stabilized.
Under norma l conditions, the rate of oil con­
sumpt ion depends on the quality and viscosity
of the oil, the RPM (revolutions per m inute) at
which the engine is operated, the ambient
temperature and road condit ions . Further fac­
tors are the amount of oil d ilution from water
condensat ion or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to wear as mi
leage builds up, the oil consump­
tion may increase over time until replacement of worn components may become necessary.
With a ll these variab les coming into play, no
standard rate of oil consumption can be es­
tablished or specified. There is no alternative
to regu lar and frequent check ing of the o il lev ­
el, see Note.
If the yellow engine oil leve l warning symbo l
in the instrument cluster
II! lights up, you
shou ld check the oil leve l as soon as possib le

cold engine, the coo lant level should be be ­
tween the "min" and "max" markings. When
the engine is warm, the level may be s light ly
above the "max" marking.
The location of the coolant expansion tank
can be seen in the engine compartment illus­
tration
r:::;, page 222.
To obtain an accurate reading, the engine
must be switched
off.
The expansion tank in you r vehicle is equipped
with an e lectric coolant level sensor.
When the coolant level is too low, the warning light in the Auto-Check System
r:::;, page 16 will
i l lum ina te unti l you add coolant and the level
has been restored to normal. Even though
there is an electric coolant level senso r, we
still recommend you check the coolant leve l
from time to time.
Coolant los s
Coolant loss may indicate a leak in the cool ing
system. In the event of coolant loss, the cool ­
ing system should be inspected immediately
by your authorized Audi dealer. It is not
enough merely to add coolant.
I n a
sea led system, losses can occur only if
the boiling point of the coolant is exceeded as
a result of overheat ing.
A WARNING
The cooling system is under pressure and
can get very hot. Reduce the risk of scald­
ing from hot coolant by following these
steps.
- Turn
off the engine and allow it to cool
down.
- Protect yo ur face, hands and arms from
escaping fluid and steam by covering the
cap with a large, thick rag.
- Turn the cap slowly and very carefully in
a counter-clockwise direction wh ile ap­
plying light, downward pressure on the
top of the cap.
- To avoid be ing burned, do not spill ant i­
freeze or coolant on the exhaust system
'
or hot engine parts. Under certain cond i­
tions, the ethylene glycol in engine coo l­
ant can catch fire.
(D Note
Do not add any type of radiator leak sea l­
ant to your vehicle's engine coolant. Add­ i ng radiator repa ir fl uid may adverse ly af­
fect the funct ion and performance of your
cooling system and could result in damage
not covered by your New Veh icle L imited
War ranty.
Adding coolant
Be very careful when adding engine coolant.
Before you check anyth ing in the eng ine com­
partment,
always read and heed all W ARN­
