Waxing and Polishing
W axin g
A good wax coating protects the vehicle paint
to a large extent against the environmental
factors listed under¢
page 194, Washing and
even against slight scratches.
You can use a liquid car wax to protect your
paint as soon as one week after your vehicle
has been delivered.
Even if you regularly use a
w axin g process in
automatic car washes, we recommend that
you manually apply a coat of wax to give the
paint extra protection, part icularly if water no
longer beads on the clean paint .
Protect plastic body parts with car wax in the
same way as the vehicle
body.
During warm weather dead insects tend to
collect on the front bumper and on the for­
ward area of the hood . They are much easier
to remove from pa int that is waxed
often.
Polishing
Polish yo ur vehicle only if the paint has lost its
shine and the gloss cannot be brought back
with wax .
If the polish used does not conta in preserva­
tive compounds, the paint must be waxed af­
terwards.
A WARNING
A lways read and heed all WARNINGS and
other information ¢

(D Note
Do not use car wax on
- matte o r anodized meta l trim
- rubber or rubber-like t rim .

Trim strips
Metal trim needs special care.
For environmenta l reasons, Audi fabricates
the br ight trim strips and trim pieces from
pure chromium-free aluminum.
Dirt and marks on the trim strips should be
removed with a
pH -b ala nced cleaning agent
(do not use a chrome cleaner). Authorized
Aud i dealers carry clean ing products w hich
have been tested for use on your veh icle and
are not harmful to the env ironment .
To avoid corros ion on the exterior trim str ips,
only a pH-balanced solution should be used
for the w indshield washer .
A WARNING
Always read and heed all WARNINGS and
other information ¢

200 Cleaning and protec tio n
The best way to remove snow from windows
and mirrors is to use a brush. Use a non-abra­
sive
plas tic ice scraper -better still, a spray
de icer -to remove
ic e from windows and mir­
rors.
The windows must not be cleaned with insect remover or wax s ince these can interfere with
the function of the windshield wiper blades (chatter).
Oi l, grease, or silicone residue can be removed
with
gl ass clea ner or silic on e remo ver. How­
ever, wax residue requires the use of a special­ ly formulated solvent. Please contact your au­
thor ized Audi dealer for adv ice on safe prod­
ucts for wax removal.
W indows shou ld also be cleaned on the inside
at regular intervals.
Never dry windows with the same chamois
that you use to dry painted surfaces. Wax resi­
due on the chamois can impair vision through
the w indows.
.&_ WARNING
- Always read and heed all WARNINGS and
other information ~
page 194.
-The windshie ld must not be treated with
water-repellent materials . They can in­
crease glare under poor visib ility condi­
tions such as wetness, darkness, or when
the sun is low on the hori zon. In addi­
t ion, they can cause the win dshield wip­
ers to chatter.
(D Note
- Never use warm or hot water to remove
snow and ice from windows and mirrors.
This cou ld cause the g lass to cra ck.
- To preven t damage to the wi res of the
rear defogger, do not place any adhe sive
stickers on the inside of the rear window
ove r the wires .
- To he lp prevent d irt from sc ratch ing the
window, always scrape in a forward di ­
rection -pushing the scraper away from
you -never back and fo rth. -
Water leaking from the ins ide of the rear
windows may damage sensitive electrical components located either under the
rear parcel shelf or in the rear trunk area.
Always ensure that water never leaks
through the body section of the vehicle.
You can do th is by us ing waterproof pro­
tection over the vehicle's electrical com­
ponents (e.g. when install ing window
tinting) .

Natural leather
App lies to vehicles: with natura l leather
Audi makes great efforts to maintain the
properties, natural look and feel of interior
leather.
G ene ra l
We offer many different types of leather on
our veh icles. Most are different types of nappa
leather, which has a smooth surface and
comes in various co lors.
The intensity of the color determines the visu ­
al characteristics and appearance . If the sur­
face of the leather has a typical natural look,
then the leather is a nappa leather that has
been left in a relatively natural condition. This
leather offers particularly good comfort and
breathes well. F ine veins, closed grains, insect
b ites, skin folds, and subtle variations in co lor
remain visible. These cha racte ristics demon­
strate that the mater ia l is na tural.
Natural nappa leather is not covered by a col­
or finish.
It is therefore more sensitive to so il­
ing and wear, wh ich is something you need to
consider if ch ild ren, an imals o r othe r factors
m ight prove to be particularly hard on the
l eather .
By contrast, leather types that are cove red by
a co lored finish laye r are more durable. This
h as a posit ive effect on the leather's resist­
ance to wear and soiling in daily use . On the
other hand, the typical characteristics of natu­
ra l leather are bare ly or not apparent. Howev­
er, this does not mean that the leather itself
is of infer ior quality.
Ca re 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-
Cleaning and protec tion 203
ful with these leathers, and a ce rtain type of
care is required. For example, dark clothing
mater ia ls can disco lor leather seats (especia l­
l y if such clothing is damp and was not dyed
correctly). Dust and dirt particles in pores,
folds, and seams can have an abrasive 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 relat ively
long time, your leather seats will acqu ire a
rich aged fin ish. This is a character istic of nat­
ural leathe r and a s ign of true quality.
In order to maintain the value of this natural
product over the life of your ve hicle, you
shou ld follow the recommendat ions below:
CD Note
- To keep your leather from b leac hing out,
do not allow it to be exposed to bright
sunlight for long periods of time. If you
have to leave the veh icle parked outside
for long per iods, cover the leather to
protect it from direct exposure to s un­
light.
- Sharp objects on clothing, such as zip­
pers, rivets or sharp pieces on belts can
leave permanent sc ratches or scrape
marks on the surface of the leather .
{i) Tips
-After each time you clean the leather and
at regular intervals, use a leather preser­
vative cream that contains UV-b lockers
and that works into the leather. Th is
cream will nour is h and mo isturize the
leather, helping it to breathe and stay
supple. It also helps to build up a protec­
tive coating on the surface .
- Clean the leather every 2 - 3 months,
and clean any 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 us ing a special colored leather care
cream to touch up areas of uneven color. •

Engine oil
· Engine oil specifications
The engine oil used in your Audi needs the
right kind of oil.
The eng ine in your Audi is a sophist icated
power plant that was b uilt to exacting specifi­
cations . Th is engine needs the right k ind of
engi ne oil that meets specifica tions regard ing
quality a nd v iscosity so that it can run
smooth ly and reliab ly. Choosing the rig ht o il
and changing oil within the t ime and mile age
i n tervals prin ted in you r vehicle's Warr anty
&
Maintenance booklet matters a lot more to ­
day tha n it did years ago . Aud i has deve loped
a spec ia l quality standard for engine oil that
will help assure that your vehicle 's engine w ill
get the lubr ication it needs for proper opera-
t ion . ..,_

216 Check ing and filling
temperatures stay below freezing point for
long periods.
Detergent addit ives in the o il w il l make fresh
oil look dark after the eng ine has been run­
ning for a short time . This is norma l and is not
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. Your 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 combustion 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 187) 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
sumption depends on the quality and viscosity
of the oil, the RPM (revolutions per minute) 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
I! in the instrument cluster lights up, you
