Washing your vehicle with a power washer
C le aning the exterior of y our car wit h a hi gh-pressur e
p ower washe r is s afe as long as you observe a few simple
r ul es .
- Before using t he power washer, make su re yo u have read
and und ers tood th e WARNI NGS =:::>
& in "General in for­
mation" o n
page 270. -
Always fo llow t he operat ing inst ructio ns for the power
washer .
- Make su re that t he jet o n th e sp ray hose produces a "fan
s ha ped spr ay".
- Do
not hold the spray nozz le too close to soft ma terials.
W hen cleaning the vehicle with a power washer always fo llow the
operat ing in str uctio ns. T his appli es p art icu larly to t he
operating
pressure
and the spraying distance . Maintain a suffic ient distance to
so ft ma ter ia ls s uch as rubbe r hoses an d so und/v ibration deaden ing
materials (part icular ly on the unde rside o f the engine hood) . Do not

0 Note
To avoid damaging your vehicle, always ma ke su re that there is suffi­
cien t dista nce between the spr ay head and sof t mate ria ls like r ubber
hoses, p lastic parts and sound-deadening mater ials. Never aim the
spr ay he ad at the s ame po int for a long t ime . This also ap plies to
cleaning headlights and pai nted b umpe rs. Remember : the close r the
noz zle is to the surfa ce of the mate rial, t he greate r the stress on the
material. •

Plastic and vinyl
Plastic needs special care.
Use a clean, damp cloth or sponge to remove dust and light surface
dirt. For other soil, use a lukewarm all-purpose cleaning solution or a
mild saddle soap for vinyl trim . Remove water spots and traces of
soap with a clean, damp cloth or sponge. Use a clean, soft cloth to rub
dry.
Grease, tar or oil stains can be removed with a clean cloth or sponge
soaked with all-purpose cleaner or with a solvent designed especially
to clean vinyl.
Occasionally apply a colorless vinyl or leather preservative to retain
the material 's luster and pliability.
& WARNING

Touch-up paint
Minor paint damages should be touched up immediately.
- Use either a touch-up paint stick or spray paint to cover
minor scratches and nicks.
Your Audi dealer has touch-up paint for minor scratches and stone
chips . Scratches should be touched up soon after they occur to
prevent corrosion.
If a spot starts to rust, however, a simple touch-up job will not be
enough. The affected surface must be sanded smooth and coated
with an anti-rust primer before the painted finish can be restored.
The number for the original vehicle paint can be found on the vehicle identification label=>

Care of interior
MMI display
- Clean the MMI display with a soft clean cloth and an LCD
cleaner .
The MMI display can be cleaned with a professionally available "LCD
cleaner". The cloth should be slightly dampened with the cleaning
fluid to clean the d isp lay .
0 Not e
To avoid scratching the MMI display, you should never clean it dry. •
MMI terminal
- First clean the MMI terminal with a brush to remove dust
from the housing.
- Then wipe the MMI terminal with a clean, soft, slightly
damp c loth .
The MMI te rmi nal shou ld be cleaned with a b rush first so that no di rt
is trapped between the buttons and the housing. We recommend
giving the MM I termina l a final wipe w ith a cloth moistened with
water and dish wash ing detergent .
0 Note
To prevent damage, make sure that no fluid ever gets into the MMI
terminal. •
Safety first
Aluminum trim
Use only neutral-pH products to remove spots and deposits from
al uminum surfaces. Ch rome care prod ucts and al kaline cleaners w ill
attack aluminum surfaces and can damage them over t ime .
& WARNING
Alw ay s re ad and heed all WARNING S and other information
~ page 2 70. •
Fabrics and fabric coverings
Fabrics and fabr ic coverings (e .g . seats, door trim panels, etc.) should
be clean ed at regular interva ls with a vacuum cl eaner . T his removes
surfa ce di rt pa rt icl es which co uld become embedded in the fabr ic
through use . Steam cleaners should not be used, because the steam
tends to push the d irt deeper into the f abric and lock it there.
Norm al clean ing
Genera lly, we recommend using a soft sponge or a li nt-free
microfiber cloth to the clean fabric. Brushes should on ly be used for
ca rpets and floor mats , since other fab ric surfaces could be ha rmed
by brushes.
No rma l sur face sta ins can be cleaned us ing a commercially avai lab le
foam cleaner. Spread the foam on the surface of the fabr ic with a soft
sponge and work it in gently . Do not saturate the fabric. Then pat the
foam dry using absorbent , dry cloths (e .g. microfiber cloth) and
vacuum it after it has dried comp letely.
Clean ing stains
Sta ins caused by beverages (e .g. coffee, fruit juice, etc.) can be
treated with a mild detergent solut ion. Apply the detergent solut ion
with a sponge . In the case of stubborn stains, a detergent paste can
be applied directly to the stai n and worked into the fabric . After­
wards, use copious amounts of clean water to remove the remaining .,.

consider if childre n, animals or other factors might prove to be partic­
ularly hard on the leathe r.
By contrast, leather types that are covered by a colored fin ish layer
are more durable . This has a positive effect on the leath er's resistance
to wear and so iling in daily use. On the othe r hand, the typical charac­
teristics of natura l leathe r are barely or not apparent . However, this
does not mean that the leathe r itself is of infer io r quality.
C are and handling
Because of the exclusive nature of the types of leather that Audi uses
and the ir unique p roperties (such as sensitivity to oils, grease, so iling,
etc.), yo u will need to be somewhat ca refu l with these leat he rs , a nd
a certain type of care is required. For example, dark clothing mate­
r ials ca n disco lor leather seats (especially if such clothi ng is d amp and
was not dyed correctly) . Dust and dirt particles in pores, folds, and
seams can have an abrasive effect and c an damage the le athe r
surface as well as weaken seams .
The leather s houl d be cleaned regularly as needed . After having been
used for a relatively long time, your leather sea ts w ill acquire a rich
aged finis h. This is a characteristic of natura l leather and a sign of
true quality.
I n order to maintain the value of this natural product over the life of
your vehicle, you sho uld fo llow the recommendations below :
0 Note
• To keep you r leather from b leaching out, do not allow it to be
exposed to bright sunl ight for long periods of time . If you have to
leave t he veh icle parked outside for long pe riods, cover the leather to
protect it from direct exposure to sunlig ht.
• Sharp objects on clothing, such as zippers, rivets or sha rp pieces
on belts can leave permanent scratches or scrape marks on the
s u rface of the leather.
Safety first
(I] Tips
• After each time you clean the leathe r and at regular inte rvals , u se
a leather preservative creme that contains UV-blockers and that
works into the leather. This creme will nou rish and mo istur ize the
leather, helping it to breathe and stay supp le. It also helps to build up
a p ro tect ive coa ting on the surfa ce.
• Clean the leather every 2 -3 months, and clean any areas that get
soiled.
• Remove fresh marks made by ballpoint pens, ink, lipstick, shoe
polish, etc. as soon as poss ible.
• Preserve the color of t he leather as needed by using a specia l
co lored leather ca re creme to touch up areas of uneven color .•

Cleaning and caring for leather upholstery
and trim
Natural leather requires special care and attention.
Normal cleaning
- Clean so iled areas wit h a slightly mois tened cotton or
woolen cloth .
More stubborn dirt
-More stubborn d irt can be removed using a clot h satu­
rated w ith a mild soap solution (2 ta blespoons m ild liq ui d
soap) .
- Never allow the soap solution to saturate the leather, and
make certa in that no water soaks i nto the seams .
- Wipe off the soap solution w ith a soft, dry c loth. .,,

Engine oil consumption
Th e e ngin e in your v ehi cle dep ends on an ad equate
amount of oil to lubricate and cool a ll of its movin g parts.
In order to p rovide e ffect ive lubric ation and cooling of inter na l
eng ine components, all internal combust ion eng ines consume a
c ert ain a mo unt o f oil. Oil co nsump tion va ries from e ngine to eng ine
and may change sign ifican tly over the li fe of the engine . Typically,
eng ines w ith a sp ecifie d brea k-in period (s ee =>
page 261) co nsum e
more o il dur ing the break -in period t han they cons ume a fter oil
cons umption has stabilize d.
Under norm al cond itions, th e ra t e of oil con su mp tio n depe nds on t he
quality and v iscosi ty of the oil, the RPM ( revolutions pe r minute) at
w hich the engi ne i s op erate d, the ambie nt te m pe ratu re and r oad
conditions. Further factors are the amount of oi l di lution from water
co ndens ation or f uel re sidue and th e oxid ation level of the oil. As any
eng ine is s ubject to wear as mileage builds up, the oil consumption
may increase over time until replacemen t of wo rn components may
become necessa ry .
With all these varia bles comin g into play, no stan dar d rate of oil
