@ Tips
- But even energy management cannot
negate the limits o f physics. Consider
that the power and life of a battery are
li mited.
- If starting ab ility is threatened, you are
i nformed by a warning
¢ page 157,
Driver notification in the instrument
cluster display.
What you should know
The highest priority is given to maintaining
starting capability.
The battery is severely taxed in short-distance
driving, in city traffic and during the co ld time
of year. Abundant e lectrica l energy is re­
quired, but only a litt le is generated. It is also
cr itical if the engine is not run ning and electri­
cal components are turned on. In th is in­
stance energy is being consumed but non e is
be ing gene rated.
It is in precisely these situations that you w ill
notice energy management actively regulat ­
in g the distribution of energy .
Vehicle stands for an extended period
If you do not drive your vehicle over a period
of several days or weeks, electrical compo­
nents are gradually cut back or switched off.
This reduces energy consumption and mai n­
tains sta rting capab ility over a longer per iod.
Take into consideration that when you un lock
your ve hicle, some co nvenience functions,
such as the remote key or power seat adjust ­
ment, may not be available . The convenience
f u nctions w ill be ava ilable again whe n you
turn on the igni tion and star t the eng ine.
With the engine turned off
If you listen to the radio, for example, with
the eng ine turned off, the battery is being dis­
charged .
Intellig ent technolog y 157
If starting capability is jeo pardi zed d ue to en ­
ergy consumption, a message appears in the
drive r information d isplay .
You have to start t he engine to charge the
batte ry .
With the engine running
Although e lectrical energy is generated when
the ve hicl e is being driven, t he battery can be­
c ome disc harged. This happe ns mostly when
li ttle energy is being generated and a g reat
deal consumed and t he battery's sta te of
c h arge is not optimal.
T o b ring the energy b alance b ack into equili ­
br ium, consumers which requ ire espe cially
la rge amounts of energy a re temporari ly cut
back or switched off . Heating systems in pa r­
ticu lar require a great deal of energy. If yo u
notice, for example, that the heated seats* or
the heated rear window are not heating, they
have been temporarily cut back or sw itched
off . These systems w ill be available again as
soon as the ene rgy balance has been restored.
You w ill also notice that engine id le speed has
been increased slightly . T hi s is normal and not
a cause for conce rn . By i ncreas ing eng ine id le
speed the additional energy r equired is gene r­
ated and the battery is charged.
Driver notification in the instrument
cluster display
If battery power drops into the range where it
can limit the ability of the engine to start, this
is shown in the instrument cluster display
with the following driver message:
(•) Low battery charge: battery will be
charged while driving
T his no tificat ion reminds yo u that the star ting
capability of the engine may be lim ited . As
soon as you sta rt dr iving again, the battery
will be recharged and the not ificat ion w ill go
out. •

Automatic car wash
The vehicle can be washed in almost any
modern automatic car wash .
The vehicle paint is so durable that the vehicle
can normally be washed without problems in
an automatic car wash. However, the effect on
the paint depends to a large extent on the de­
sig n of the fac ility, the filtering of the wash
water, the type of wash and care mater ial , etc.
If the paint has a dull appearance afte r go ing
through the car wash or is scratched, bring
this to the attention of the operator immedi­
ately. If necessary, use a different car wash.
Before going through a ca r wash, be s ure to
take the usual precautions such as closing the
windows. Remove antenna if applicable .
If you have installed additional accessories on
the vehicle -such as spoilers, e tc. -it is best to
ask the car wash operator i f these should be
removed .
A WARNING

- 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 . ..,.

168 Cleaning and protection
Do not use car wax on
- matte or anodized metal trim
- rubber or rubber-like trim.
Trim strips
Metal trim needs special care.
For environmental reasons , Audi fabricates
the bright trim strips and trim pieces from pure chromium-free aluminum.
Dirt and marks on the trim st rips should be
removed with a
pH-balanced cleaning agent
(do not use a chrome cleaner). Audi dealers
carry cleaning products which have been test­
ed for use on your vehicle and are not harmful
to the environment .
To avoid corrosion on the exterior trim strips,
only a pH-balanced solution should be used
for the windshield washer .
.&_ WARNING
Always read and heed all WARNINGS and
other information
c> page 164.
Plastic and vinyl
Plastics 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 soap traces 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
Always read and heed all WARNINGS and
the information
c> page 164.
Aluminum trim '
Use only neutral-pH products to remove spots
and deposits from aluminum surfaces.
Chrome care products and alkaline cleaners
will attack aluminum surfaces and can dam­
age them
over time.
A WARNING
Always read and heed all WARNINGS and
the information

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 pre­
vent corrosion.
The number for the original vehicle paint can
be found on the vehicle identification label

Windows
Clear vision to all sides .
Clean all windows regularly to remove road
film and carwash wax buildup.
.. Remove snow from windows using a brush .
.. Use a plas tic ice scraper to remove ice from
windows and mirrors .
.. Remove other residue on the windows with
a spray-on glass cleaner.

~ Wipe the windows dry with a clean piece of
cloth or kitchen paper towel.
The best way to remove snow from windows
and mirrors is to use a brush. Use a non-abra­
sive
plastic ice scraper -better still, a spray
deicer -to remove
ice from windows and mir­
rors.
The windows must not be cleaned with insect
remover or wax since these can interfere with
the function of the windshield wiper blades
(chatter).
Oil, grease or silicone residue can be removed
with
glass cleaner or silicone remover. How­
ever, wax residue requires the use of a special­
ly formulated solvent. Please contact your
Audi dealer for advice on safe products for
wax removal.
Windows should 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 windows.
A WARNING
-The windshield must not be treated with
water-repellent materials. They can in­
crease glare under poor visibility condi­
tions such as wetness, darkness, or when
the sun is low on the horizon. In addi­
tion, they can cause the windshield wip­
ers to chatter.
- Always read and heed all WARNINGS and
other information
¢page 164.
(D Note
-Never use warm or hot water to remove
snow and ice from windows and mirrors.
This could cause the glass to crack.
- To prevent damage to the wires of the
rear defogger, do not place any adhesive
stickers on the inside of the rear window
over the wires.
- To help prevent dirt from scratching the
window, always scrape in a forward di-
Cleaning and protection 169
rection -pushing the scraper away from
you -never back and forth.
· Steel wheels
Applies to vehicles : with steel wheels
The wheels also have to be cleaned.
~ Always include the hub caps and wheel rims
when washing your vehicle to remove road
dirt, salt sprays and brake dust.
If necessary, use a commercial wheel cleaner
to remove accumulated brake dust.
The wheel rims are easier to keep clean if they
are regu larly coated with liquid wax.
Paint scratches should be touched up as soon
as possible to prevent corrosion

information.
Test the brakes carefully af­
ter each vehicle wash.
- Always read and heed all WARNINGS and
the information
¢page 164.
Cast (light) alloy wheels
Applies to vehicles: with Cast alloy wheels
Cast (light) alloy wheels require special care.
~ Wash the wheels with a sponge or hose
brush every other week.
~ For deep cleaning afterwards, use only a
dedicated
acid-free cast alloy wheel cleaner .
~ Rub a coat of liquid wax onto the rims every
three month. Be sure to reach and treat all
parts of the rim.
To preserve the decorative appearance of the
cast alloy wheels, some special care is neces­ sary. In addition to road dirt and salt, brake
dust is also corrosiv e. If left on for too long,
brake dust can cause pitting.

Battery
General information
Your vehicle is equipped with a specia l bat ­
tery, an
ACM battery. This battery is located
in the luggage compartment and must be re­
placed with an origina l equipment battery .
U nder normal opera ting condit ions, the bat­
te ry is
maintenance-fr ee .
Have the battery checked when you take your
vehicle in for serv ice . You a re well advised to
replace a battery that is o lde r th an 5 years .
Disconnecting the battery terminals
Some vehicle functions (power window reg u­
lators, for example) are lost if the battery te r­
mina ls are disconnected . T hese functions have
to be relearned after the battery termina ls are
connected again . T o p revent t his, t he battery
shou ld only be disconne cted from the veh icle
elect ric a l sys tem when abso lutely ne cessary
f or rep air s.
Vehicles not driven for long periods
If you do not drive your vehicle ove r a period
of seve ral days o r weeks , e lectr ica l compo-
nents a re g radually cut back or switched off.
Ill-

This reduces energy consumption and main­
tains starting capability over a longer period
c::>
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.

@ 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

@ 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 .
