166 Cleaning and protection
sponges to prevent scratches. It is best
to use soapy water .
- You should remove debris (such as in­
sects) from the headlight lenses on a
regular basis, for example when refuel­
li ng your vehicle.
@ For the sake of the environment
On ly wash the vehicle in facilit ies specially
designed for that purpose. This w ill reduce
the risk of d irty water contaminated with
oil from entering the sewer system. In
some areas, washing vehicles outs ide of
these facilities is prohib ited.
Washing your vehicle with a power
washer
Cleaning the exterior of your car with a high­
pressure power washer is safe as long as you
observe a few simple rules.
• Before using the power washe r, make sure
you have read and understood the WARN­
I N GS 9 .&. in General information on
page 1 64.
• Always fo llow the opera ting ins truc tions for
the power washer.
• Make sure that the jet on the spray hose
produces a "fan shaped spray" .
• Do
no t ho ld the spray no zzle too close to
soft materia ls.
Keep a distance from soft materials such as
rubber hoses or insulat ing mater ial as we ll as
sensors and camera lenses.
When clea ning the vehicle wit h a power wash ­
er
always f o llow the operating instructions .
This applies particularly to the operating pres­
sure and the spraying distance. Do not po int
the spray directly at the sea ls around the s ide
windows, a round t he doors, on the rear lid or
on the su nroof* . Likew ise, do not point it di­
r e ctly at t ires, r ubber hoses, insul ation mate ­
rial or sensors. Hold t he sp ray noz zle at least
1.3 ft ( 0.4 m) away from the vehicle.
D o not use a h igh-pressure powe r washer to
r emove snow and i ce. D
o not use a jet which sprays water in a d irect
stream o r one that has a rotating jet .
Water temper ature sho uld n ot ex ceed 140 °F
(6 0 °C).
A WARNING ~ -
N eve r wash t ires wi th a jet that sprays wa­
ter i n a direct stream. This could cause in ­
v is ib le damage to the t ires and weaken
them, even if the spray is from a re lative ly
l ong distance and for a short time. Dam­
aged and weakened tires can fail a nd cause
a ccidents and pe rsonal i njury.
([) Note
To avoid damaging your vehicle, a lways
make sure that there is suffic ient d istance
between the spray head and soft materia ls
like rubber hoses, plast ic pa rts and sound­
deade ning ma ter ia ls as w ell as s ensors
and camera lenses. Neve r aim t he sp ray
head a t the same point fo r a long time.
This also applies to cleaning headligh ts
and painted bumpers. Remembe r: the
closer the nozzle is to the surface of the
materia l, the greater the stress on the ma ­
terial.
Caring for vehicles with matte finish
paint
Applies to vehicles: with matte finish paint
Vehicles with ma tte finish paint require spe­
cial care due to the characteristics of the
paint.
Wa shing by hand
To avoid damaging the paint when washing,
first remove dust and large par ticles from
your vehicle. Insects, grease spots and fi nger­
pri nts are best removed w ith a
special cleaner
for matte finish paint .
Apply the product us ing a microfiber cloth . To
avo id damag ing the pa int surface , do not use
too much pressure . ..,.

170 Cleaning and protection
the rims longer than specified on the label. If
not rinsed off promptly, the acid contained in
some cleaners can attack the threads on the
wheel bolts.
Never use abrasive or metal polishing clean­
ing agents. If the protective coating has been
chipped, e.g. by kicked up road dirt, touch it
up as soon as possible.
A WARNING
-Moisture and ice on brakes may affect
braking efficiency¢
page 153, General
information.
Test the brakes carefully
each time you wash the vehicle.
- Always read and heed all WARNINGS and other information
qpage 164.
Body cavity sealing
The body cavity sealing does not need to be
checked.
-
All body cavities which could be affected by
corrosion have been given thorough protec­
tion at the factory.
This sealing does not require any inspection or
additional treatment. If any wax should seep
out of the cav ity when the ambient tempera­
ture is high, it can be removed with a plastic
scraper and a suitable solvent.
A WARNING
, -
Solvents can be dangerous.
- Benzine is flammable and toxic. If you use benzine for removing the wax, keep
sparks, flame and lighted cigarettes
away. Never dump benzine on the
ground, into open streams or down sew­
age drains.
- Be sure to observe all safety and environ­
mental regulations. Follow all instruc­
tions on the container.
- Always read and heed all WARNINGS and
the information
¢page 164.
Chassis
Have the undercoating checked for damage
from time to time.
The lower body shell of your Audi is also thor­
oughly protected against corrosion.
Any damage to the undercoating caused by
road hazards should be repaired promptly.
A WARNING
-Too much undercoating in the wrong pla-
ces can cause a fire.
- Do not apply additional undercoating or
rustproofing on or near the exhaust
manifold, exhaust pipes, catalytic con­
verter or heat shields. While driving, the
substance used for undercoating could
overheat and cause a fire.
-Always read and heed all WARNINGS and
other information¢
page 164.
Exhaust tail pipes
Road salt and other corrosive materials will
damage the material in the exhaust tail pipes
if they are not cleaned regularly. Do not clean
the tail pipes with wheel cleaner, paint polish, chrome polish or other abrasive cleaners.
Clean the tail pipes with car care products
t h at are suitable for stainle ss steel.
Your authorized Audi dealer can provide clean­ ing products that have been tested and ap­
proved for your vehicle.
Care of interior
Radio-/Navigation* display
.. Clean the display with a soft clean cloth and
an LCD cleaner.
The display can be cleaned with a professio­
nally available "LCD cleaner ". The cloth should
be slightly dampened with the cleaning fluid
to clean the display. .,.

184 Checking and filling
Detergent additives in the o il will make fresh
oil look dark after the engine has been run­
n ing for a short time . This is norma l and is not
a reason to change the oil more often than recommended.
D am ag e o r m alfun ction s due to lack of
m ainten ance
It is essent ial that yo u change your oil at the
recommended intervals using only engine oil
that complies with Audi oi l standard
VW 502 00 . Your Lim ited New Vehicle War­
ranty does not cover damage or malfunctions
due to failure to follow recommended mainte­
nance and use requ irements as set forth in
the Audi Owner's Manual and Warranty
&
M aintenance book let . Your dea ler will have to
deny warranty coverage un less you p resen t to
the dea ler proof in the form of Servi ce or Re­
pa ir Orde rs that all schedu led maintenance
was performed in a timely manner.
Engine oil consumption
The engine in your vehicle depends on an ade­
quate amount of oil to lubricate and cool all
of its moving ports.
I n o rder to prov ide effective lubr ication and
cooling of internal engine components, a ll in­
ternal comb ustion engines consume a certain
amount of oil. Oi l consumption varies from
engine to engine and may change significantly
over the life of the eng ine . Typically, eng ines
with a specif ied break-in per iod (see
c::;, page 159) consume more oil during the
break-in per iod than they consume after oil
consumption has stabilized .
Under normal conditions, the rate of oil con­
sumpt io n 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 cond it io ns. Furthe r fac­
tors are the amo unt of o il d ilution from wate r
condensation or fuel residue and the ox ida­
tion level of the oi l. As any engine is subject to
wear as mileage bui lds up, the oil consump­
tion may increase over t ime until replacement
of worn components may become necessary. Wi
th a ll these variab les coming into p lay, no
standard rate of oil consumption can be es­
tab lished or spec ified. There is no alte rnative
to regular and frequent check ing of the o il lev­
el, see
Note .
If the yellow engine oil leve l warning symbo l
in the instr ument cluster
II lights up, you
sho uld check the oil leve l as soon as possib le
with the oil dipstick c::;, page 185. Top off the
o il at your earliest conven ience
c::;, page 185 .
A WARNING
-Before you chec k anything in the eng ine
compartment, a lways read and heed a ll
WAR NINGS
c::;, .& in Working in the engine
comportment on page 180.
CI) Note
D riving with an insufficient o il level is like­
l y to cause sever e damage to the engine.
(D Tips
- The oil pressure warn ing display. is
not an indicator of the oil level. Do not
re ly on it . Instead, check the oil level in
your engine at regular intervals, pr ef­
erably ea ch time you refu el, and alway s
before going on a long trip.
- If you have the impression yo ur engine
cons umes excessive amoun ts of oil, we
recommend that you consult your Aud i
dealer to have the cause of your concern
properly diagnosed. Keep in mind that
the accurate meas urement of o il con­
sumption requ ires great care and may
take some t ime . Your Audi dea ler has in­
struct ions about how to measure oil con­
sumption acc urately.

This reduces energy consumption and main­
tains starting capability over a longer period

page 156. Some of the convenience func­
tions may not operate, such as the interior
lights or power seat adjustment. The conven­
ience functions will be ava ilable again when
you switch on the ignition and start the en­
g ine .
Winte r oper ati on
During the winter months, battery capacity
tends to decrease as temperatures drop. This
i s because more power is also consumed while
start ing, and the headlights, rear window de­
fogger, etc., are used more often .
Avoid unnecessary power consumption, par­
ticularly in city traffic or when traveling only
short distances . Let your authorized Audi
dealer check the capac ity of the vehicle bat­
tery before winte r sets inc::>
page 193. A we ll
charged ba tte ry w ill no t only prevent starting
prob lems when the weathe r is cold, but will
a lso last longer .
Replacing battery
The new battery must have the same capaci­
ty, vo ltage ( 12 volts), amperage, cons truction
and p lug sealing, as the origina l ba tte ry. Spec­
if ications are listed on the batte ry housing.
Batteries specially developed by A udi fulfill
the maintenance, output, and safety require­
ments.
When insta lling the battery, make sure the ig ­
nition and all electrica l cons umers are switch­
ed off c::>
(i).
We recommen d that yo u use ma intenance­
free or
cy cle- re sis tant /leak-pr oof batteries
according to the standards TL 825 06 (from
April 2008) and VW 7 SO 73 (from Apri l
2010).
Replacing the batte ry should be carried by a
q ua lified workshop. P lease follow the instruc­
tions on the battery cover.
Checkin g and fillin g 191
@ Note
-All work on the battery requires techni­
cal know ledge. Please contact an Audi
dealership or another authorized fac ility
for questions about the battery - danger
of ac id burns and exp losion hazard!
- The battery must not be opened! Do not
try to change the battery 's liquid level,
otherwise detonating gas will escape
from the battery - explosion hazard!
- The AGM battery in the luggage com­
partment cannot leak, because the elec­
t ro lyte for this batte ry is abso rbed into a
special glass mat. This lea k-proof battery
must not be replace with a convent iona l
bat tery.
- Make su re the ventilation hose on t he
side of the ba ttery is connected, othe r­
w ise fumes or battery ac id can leak out.
- Batte ry holder and termin als always
have to be sec ured correc tly.
- Before all work on the batte ry follow the
warning s below c::> .&. in Working on the
battery on page
192 .
@ For the sake of the environment
Because of the p rob lem of proper disposal
of a ba ttery, we recommend your author­
i zed Audi dealer change the bat tery fo r
you. Batteries contain sulfuric acid and l ead and must always be disposed of prop ­
erly in comp liance with a ll environmental
regulat ions. Disposing of vehicle batter ies
i mproperly is very dangerous to the envi­
ro nment. Make sure that the removed bat­
tery cannot overbalance, othe rwise sulfu­
r ic acid might escape!
@ Tips
If your vehicle is left standing for several
weeks at extremely low temperatures, the
vehicle battery shou ld be removed and
stored w here it w ill not freeze. This will
p revent it from be ing dam aged and h aving
to be replaced .

lowing pages if you are not fu lly fam iliar
with these or other procedures with re ­
spect to the vehicle, or are uncertain how
to proceed .
- Do not do any work without the proper
too ls and equipment. Have the necessa ry
work done by your authorized A udi deal­
er or another proper ly equipped and
qualified workshop.
- The engine compartment of any motor
veh icle is a potentially hazardous area.
Never reach into the area around or
touch the radiator fan. It is temperature controlled and can sw itch on suddenly -
even when the engine is off and the igni­
