Your authorized Audi dealer can provide cleaning products that have
bee n tested and approved for your veh icle. •
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 .•

-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
co nsum ption can be establis hed o r spe cified. Th ere is no alte rnative
to regular and frequent chec kin g of the o il level, see
Note .
If the yellow e ngine oil leve l w arning symbol in the ins trumen t
cl uster · .. lights up, yo u should chec k the o il lev el as soon as possible
with the oil dipstick=> page 293 . Top off the oil at yo ur earliest

[ i ] Tips
• The oil pressure warn ing display 'e.::1; is not an indicator of the oil
level. Do not rely on it . Instead, check the oil level in your engine at
regular intervals, preferably each time you refuel, and always
before going on a long trip .
• If you have the impression your eng ine consumes excessive
am ounts of o il, we recom mend that you cons ult your Audi dea le r to
have the cause of your concern properly d iagnosed. Keep i n m ind that
t he accurate meas urement of oil co nsum ption re quires great care
and may take some t ime. Your Audi dealer has instruct io ns about how
t o meas ure o il cons umption a ccu ra tely .•

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 especially important if you live in a region where
the winter is extremely cold. If necessary, increase the proportion of
coo lant additive to 60% .
• When adding coolant additive to your cooling system, remember:
-We recommend using only coolant additive G12++ (check the
label) for your vehicle. This coolant additive is available at autho­
r iz ed Audi dealers. Other types of antifreeze can s ignificantly
reduce corrosion protection. The resulting corrosion can cause a
loss of coolant and serious engine damage.
• Do not add any type of radiator leak sealant to your vehicle 's
eng ine coolant. Adding radiator repair fluid may adversely affect the
function and performance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty. •
Checking the engine coo lant level
The engine coolant level can be checked with a quick
glance.

Before you check anything in the engine compartment,
always read and heed all WARNINGS=> & in "Working in
the engine compartment" on
page 289.
- Turn off the ignition.
- Read the engine coolant level from the coolant expansion
tank=> fig. 247 . With a cold engine, the coolant level
should be between the "min" and "max" markings. When
the engine is warm, the level may be slightly above the
"max'' marking .
The locat ion of the coolant expans ion tank can be seen in the engine
compartment illustration=>
page 290.
To obtain an accurate reading, the engine must be switched off.
The expansion tank in your vehicle is equipped with an electric coolant level sensor .
When the coolant level is too low, the warn ing light in the Auto-Check
System =>
page 29 will blink until you add coolant and the level has
been restored to normal. Even though there is an electric coolant
level sensor, we still recommend you check the coolant level from
time to time.
Coolant loss
Coolant loss may indicate a leak in the cooling system. In the event of
coolant loss, the cooling system should be inspected immediately by
your authorized Audi dealer .
It is not enough merely to add coolant.
In a
sealed system, losses can occur only if the boiling point of the
coo lant is exceeded as a result of overheating.
& WARNING
The cooling system is under pressure and can get very hot. Redu ce
the risk of scalding from hot coolant
by following these steps.
• Turn off the engine and allow it to cool down.

ethylene glycol in engine coolant can catch fire.
0 Note
Do not add any type of radiator leak sealant to yo ur vehicle's engine
coo lant. Adding radiator repair fluid may adverse ly affect the func­
t ion and perfo rmance of your cooling system and could result in
damage not covered by your New Vehicle Limited Warranty .
[ i J Tips
On vehicles with the 12-cylinder engine, the expansion tank is located
unde r a cover. •
Adding coolant
Be very careful when adding engine coolant.
Before you check anything in the eng ine compartment,
always read and heed all WARNINGS~ & in "Working in
t h e e ngine compar tment" on
page 289 .
-Tur n off the eng ine.
- Let t he engi ne cool down. -

- Add coo lant.
- Tw ist t he cap on agai n
tightly.
Replacement eng ine coolant must conform to exact specificat ions
=> p age 2 96, "Coolan t". Even in an emergency, if coolan t ad di tive
Gl2 ++, Gl2+ or Gl2 is not available, do
not use a d ifferent addit ive.
Use plain water instead until you can get the correct additive a nd can
restore the correct ratio . This s hou ld be done as soon as possible .
If you have lost a conside rable amount of coolant , then you sho uld
add co ld a ntifree ze a nd cold water only when t he e ngine is cold .
Always use
new engine coo lant when refilling.
Do not fill coolant above t he "MAX" mark. Excess coo lant wi ll be
forced out t hrough the p ressure relief va lve in the cap w hen the
eng ine becomes hot.
& WARNING
• The cooling system is under pressure and can get very hot.
Reduce the risk of scalding from hot coolant by following these
steps.
- Turn off the engine and allow it to cool down .
- Protect your 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 while applying light, downward pressure on the top
of the cap.
- To avoid being burned , do not spill antifreeze or coolant on
the exh aust system or hot engine parts. Under certain condi-
tions, the ethylene gly col in engine coolant can catch fire. .,
