Waxing
Wax protects the vehicle's paint.
~ Use a manually app lied car wax occasiona lly
to protect the paint.
A good wax coating protects the vehicle paint
to a large extent against the environmental
factors listed under ¢ page 206, Washing and
even against slight scratches.
You can use a liquid car wax to p rotect your
paint as soon as one week after your ve hicle
has been de livered.
E ven if yo u regularly use a
waxing process in
automatic ca r washes, we recommend that
you man ua lly app ly a coat of wax to give the
pa int extra protection, particularly if water no
l onger beads on the clean paint.
Protect p lastic body pa rts with car wax in the
same way as the vehicle body.
D uring wa rm weat her dead insec ts tend to
collect on the front bumper and on the for­
ward area o f the hood. They are much easier
to remove from paint that is waxed o~en.

Fabrics and fabric coverings
Fabr ics and fab ric cover ings (e.g . seats, door
trim pa ne ls, etc.) sho uld be cleaned at regular
intervals wit h a vacuum cleaner . This removes
s ur face dirt particles which cou ld become em­
bedded in the fabric throug h use. Steam
cleaners should not be used, because the
steam tends to push the dir t deeper into the
fabric a nd lock it the re . ..,_

Normal cleaning
Generally, we recommend using a soft sponge
or a lint -free microfiber cloth to the clean fab­
ric . Brushes should only be used for carpets
and floor mats, since other fabric surfaces
could be harmed by brushes.
Normal surface stains can be cleaned using a
commercially available foam cleaner. Spread
the foam on the surface of the fabric with a
soft sponge and work it in gent ly. Do not sat u­
rate the fabric. Then pat the foam dry using
absorbent, dry cloths (e.g . microfiber cloth)
and vacuum it after it has dr ied completely.
Cleaning st ain s
Stains caused by beverages (e.g. coffee, fruit
juice, etc.) can be treated with a mild deter­
gent solution. Apply the detergent solution
with a sponge. In the case of stubbor n stains,
a detergent paste can be applied directly to
the stain and worked into the fabric. After­
wards, use copio us amounts of clea n water to
remove t he remain ing detergent. Apply the
water with a damp cloth or 5ponge and pat
the fabric d ry with an absorbent, dry cloth.
Stains from chocolate o r make up s hou ld have
dete rgent paste (e.g . ox-gall soap) r ubbed in­
to them. Afterwards, remove the soap w ith
water (damp sponge).
A lcohol can be used to t reat stains from
grease, oi l, lipstic k or a ballpo int pen. Me lted
grease or dye must be patted
off using ab ­
sorbent materia l. It may be necessary to re ­
treat the areas with dete rgent paste and wa­
ter.
I n the case of genera l so iling of the uphols­
tery and cover materia l, we recommend hiring
a specialist that has the equ ipment to clean
the seat covers and other fabric surfaces by
shampooing and spray extraction.

Natural leather

General
We offe r ma ny d iffe ren t types o f leathe r o n
our vehicles. Most are diffe rent types o f nappa

214 Cleaning and protection
leathe r, whi ch has a smooth surface and
comes in various co lors .
The intensity of the color determines the v is u ­
a l charac ter istics and appearance. If the sur­
face of the leather has a typical natu ral look,
then the leather is a nappa leather that has been left in a relatively natural cond ition. This
leather offers particularly good comfort and
breathes well. F ine veins, closed grains, insect
b ites, skin folds , and subtle var iations in co lor
remain visible . These c haracteristics demon­
strate that the mater ia l is natural.
Natural nappa leather is not covered by a col­
or fi nish . It is therefore more sensitive to soil ­
i ng and wear, w hich is something you need to
consider if ch ild ren , an ima ls or othe r factors
might prove to be particular ly hard on the
l eathe r.
By contrast, leat her types that are covered by
a co lored finish layer a re mor e durable . This
has a posit ive effect o n the leather's resist­
a nce to wear and soil ing in daily use. On the
o ther hand , the typical characteris tics of na tu­
ra l leather a re barely or not apparent. Howev ­
e r, this does not mean that the leather itself
is of infer ior quality.
Care and handling
Because of the exclusive na ture of the types of
l eather that Audi uses and the ir 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 ce rtain type of
care is required. For examp le, dark clot hing
materials can d iscolor leather sea ts (especial­
ly if such clot hing is damp and was not dyed
correctly) . Dust and d irt part icles in po res,
folds , and seams can have a n ab ras ive effect
and can damage the leathe r sur face as well as
weaken seams.
The leather should be cleaned regula rly as
needed. After havi ng been used for a re lative ly
l ong time, yo ur leather sea ts will acqui re a
ri ch aged finish. This is a charac ter istic of n at­
u ra l lea ther and a sign o f true quality . In order to maintain the val
ue of this nat ural
product over the life of your vehicle, you
sho uld follow the recommendat ions be low :
(D Note
- To keep your leather from b leaching o ut,
do not allow it to be exposed to b right
sunlight for long periods of time . If you
have to leave the ve hicle parked outside
for long per iods, cover the leather to
protect it from direct exposure to sun ­
light .
- Sharp objects on cloth ing, such as zip­
pers, rivets or sharp pieces on belts can
leave permane nt sc ratches or sc rape
ma rks on the su rface of the leather.
(0 Tips
- After each time you clean the leather and
at regular intervals, use a leathe r preser­
vative c reme that contains UV-b locke rs
and tha t works into the leat he r. Thi s
c reme will nour ish a nd moistu rize the
leather, helping it to breathe and stay
supple. It a lso helps to build up a p rotec­
tive coating on the surface.
- Clean the leat her every 2 -3 months,
and clean any a reas that get soi led .
- Remove fresh ma rks made by ballpo int
pe ns, ink, lipstick, shoe polish, etc. as
soon as poss ible.
- P reserve the color o f the leather as need ­
ed by using a specia l co lore d leathe r care
creme to touch up areas of uneven color .

t h e cleane r from the leathe r care kit if the
spot has not yet penetrated into the surface
of the leather.
"'U se an oil/grease dissolving spray, if
oil/
grease spots have d ried on.
"' Remove spec ific kinds of spots (ballpoint
pen, felt marker, fingernail polish , water­
based paint, shoe polish, etc.) with a spot
remover specifically formulated for leather .
Leather care
"'Every half year use an approved leather care
product (available from your Audi dealer) to
care for the leather.
"' Apply the product very sparingly.

Plenum panel
Remove leaves from the plenum panel in front
of the w indshield under the eng ine compart ­
ment . This prevents the wate r drain holes
from becom ing b locked, and it preve nts de­
br is from entering the vehicle inte rior through
the heat ing and ven tilat ion duc ts.
Corrosion protection
The eng ine compartment and transmission
have been corrosion-protected at the factory .
ll-

Good anti-corrosion treatment is very impor­
tant, particularly in the winter . If the vehicle
is freq uent ly driven on salt treated roads, the
entire engine compartment and plenum panel
should be thoroughly cleaned at t he end of
winter and retreated to prevent salt damage.
At the same time, the underside of the veh icle
should be washed as we ll.
If the engine compartment is cleaned at any
time with grease removing solut ions
1>, 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
l as ting co rrosion protection reapp lied to all
surfaces, seams, joints and components in the
engine compartment.
~ WARNING
