dea ler. •
Battery
General information
Your vehicle is equipped with a specia l battery, an AGM battery. This
ba ttery is loca ted in the luggage compar tment and must be
replaced with an original equipment battery. Under normal oper­
ating conditions, the battery is
ma inten anc e-free .
Have the battery checked when you take your vehicle in for service .
You a re well advised to replace a battery that is o lder than 5 years .
Disconn ecting th e batt ery te rmin als
Some vehicle functions (power w indow regulators, for example) are
lost if the battery terminals are disconnected. These functions have
to be relearned after the battery terminals are connected again. To prevent this, the battery should only be disconnected from the
vehic le electrical sys tem when abso lutely necessary for repairs .
Vehi cles not dri ven for lo ng p eriods
If you are going to let your vehic le stand for a long time and n ot
drive it, you should remember there are e lectrica l components
whic h are still functioning and they will draw energy from the
battery and drain it, for example, the engine immobilizer. To prevent
t his, you can eithe r charge the batte ry occasionally to keep it in
good working condition or you can disconnect the negative cable
on the battery.
W int er op erati on
During the winter months, batte ry capacity tends to decrease as
temperatures drop . This is because more power is also consumed
whi le starting, and the headlights, rear window defogger, etc ., are
used more often.
Avoid unnecessary power consumption, particularly in city traffic or
when trave ling o nly short distances . Let your authorized Audi dealer
check the capacity of the vehicle battery before winter sets in
~ page 232. A we ll charged battery will not only preven t starting
problems when the weather is cold, but will also last longer.
Repla cing batter y
The new battery must hav e the same capacity, voltage ( 12 volts),
amperage, construction and p lug sea ling, as the orig inal battery .
Specifications are listed on the battery housing. Batteries specia lly
developed by Aud i fulfill the main tenance, output, and safe ty
requirements. ...,

The tires and rims are essential parts of the vehicle's design. The
tires and rims approved by Audi are special ly matched to the char ­
acteristics of the vehicle and can make a major contribution to good
road ho lding and safe hand ling when in good cond ition and prop ­
erly inflated
~ & .
We recommend that all work on tires and wheels be performed by
an authorized Audi dealer . They are familiar with recommended
procedures and have the necessary special too ls and spare parts as
well as the proper facilities for disposing of the old tires.
Authorized Audi dea lers have the necessary information about tech ­
n ical requirements for insta lling or changing tires and rims .
Replacing tires and wheel s
Tires should be replaced at least in pairs and not individual ly (for
example both front tires or both rear tires together) .
Be sure to read and heed the information to the tire pressure moni ­
toring system *~ page
248 .
Always buy replacement radial tires tha t have the same specifica ­
tions as the tires approved for your vehicle by Audi . Replacement
tires must always have the same load rating specification as the
original equipment or approved optiona l tires listed in the table
~ page 238.
Audi -app roved specification tires are specially ma tched to your
vehic le and its load limits, and can contribute to the important road-~

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
ture. For example, the numbers 2209 mean that the tire was
produced in the 22th week of 2009. The other numbers are
marketing codes that may or may not be used by the tire manufac­
turer. This information is used to contact consumers if a tire defect
requires a recall.
Tire ply composition and materials used
The number of plies indicates the number of layers of rubber-coated
fabric in the tire. In general, the greater the number of plies, the
more weight a tire can support. Tire manufacturers also must indi­
cate the materials in the tire, which include steel, nylon, polyester,
and others .
Maximum Load Rating
This number indicates the maximum load in kilograms and pounds
that can be carried by the tire.
Tire quality grading for treadwear, traction, and
temperature resistance
Tread wear, traction and temperature grades => page 249.
Maximum Permissible Inflation Pressure
This number is the greatest amount of air pressure that should ever
be put in the tire under normal driving conditions.
Replacing tires or rims on vehicles equipped with tire
pressure monitoring system*
The wheels on your vehicle are equipped with a sensor which
constantly monitors the air pressure inside the tire, and then trans­
mits this information to the tire pressure monitoring system *. If you
are going to replace the wheel rims on your vehicle, make sure the
new rims also have these sensors . The sensors must be compatible
with the tire pressure monitoring system * on your vehicle.
If the sensors are to be installed on different rims , the seal, washer ,
and valve cap for each sensor must be replaced.
If you install rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring system* will not work properly.
In this case, the tire pressure moni­
toring system * would not be able to monitor the tire pressure or
warn you if it is necessary .
• The battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the valve stem caps securely mounted. We
recommend using factory installed valve stem caps. Ask your autho­
rized Audi dealer to replace lost valve stem caps.
The installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction of the tire pressure moni­
toring system*, and is not recommended (cord material information
in molded on the tire sidewall) .
Always check your tire pressure monitoring system* indicator after
replacing one or more tires on your vehicle. If the tire pressure
monitoring system* indicator flashes, or is on, your system is not
working properly. Your replacement tire might be incompatible with
your tire pressure monitoring sys tem* , or some component o f the
tire pressure monitoring system* may be damaged.
& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combinations can lead to loss of control, collision
and serious personal injury.
• Always use tires, rims and wheel bolts that meet the specifica­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
especially at high speeds. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speeds.
• Never mount used tires on your vehicle if you are not sure of
their "previous history." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. .,_

Quality grades can be found where applicable on the tire side wall
between tread shoulder and maximum section width
=> page 246,
fig. 152.
For example: Tread wear 200, Traction AA, Temperature A.
All passenger car tires must conform to Federal Safety Require­
ments in addition to these grades .
Tread wear
The tread wear grade is a comparative rating based on the wear rate
of the tire when tested under controlled conditions on a specified
government test course .
For example, a tire graded 150 would wear one and one half (1 1/2)
times as well on the government course as a tire graded 100 .
The relative performance of tires depends upon the actual condi ­
tions of their use, however, and may depart significantly from the
norm due to variations in driving habits, service practices and differ ­
ences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, Band C .
Those grades represent the tire's ability to stop on wet pavement as
measured under controlled conditions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance
=> &.
Temperature
The temperature grades are A (the highest), B, and C, representing
the tire's resistance to the generation of heat and its ability to dissi ­
pate heat when tested under controlled conditions on a specified
indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure=>& .
The grade C corresponds to a level of performance which all
passenger car tires must meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades Band A represent higher levels of
performance on the laboratory test wheel than the minimum
required by law.
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is
properly inflated and not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separately or in combination, can
cause heat buildup and possible tire failure. •
Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires.
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread. These tires
should only be used in pairs and be installed on all four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
I f your vehicle is equipped with all-wheel drive *, this will improv e
traction during winter driving, even with the standard tires.
However, we strongly recommend that you always equip all four
wheels on your vehicle with correctly fitted winter tires or all-season
tires, when winter road conditions are expected. This also improves
the vehicle's braking performance and reduces stopping distances.
Summer tires provide less grip on ice and snow.

dea ler or qua lified workshop. •
Low aspect ratio tires
Your Audi is factory-equipped with low aspect ratio tires. These t ires
have been thorough ly tested and been selected specifically for your
model for their superb performance , road feel and hand ling under
a variety of driving conditions . Ask your authorized Audi dealer for
more deta ils.
The low aspect rat io of these t ires is indicated by a numera l of
5 5 or
les s
in the tire's si ze designation. The numeral represents the ratio
of the tire's sidewa ll height in relation to its tread wid th expressed
in perc entage. Conv entiona l tires have a h eight/width ratio of 60 or
more .
The p erform an ce of lo w-aspe ct-r a tio tire s is pa rti cula rly sen siti ve to
improp er inflation pre ssure . It i s ther efore important that low
a spect ratio tir es are inflat ed to the sp ec ified pre ssure and th at the
i nflation pr es su re is regularl y checked and mainta ined . Tire pr es­
s ure s should be che cked at le ast once a month and alw ay s before a
long tr ip :::;, page
247, "Checking tire pressure".
What you can d o to av oid tire and rim d amage
Low aspect ratio tires can be damaged more easi ly by impact with
potholes, curbs, gul lies or r idges on the road, particularly i f the t ire
is underinflated.
In order to min imize the occurrence of impact damage to the tires
of your vehicle , we recommend that you observe the following
precautions:
• Always maintain recommended inflat ion pressures . Check your
tire pressure every 2 ,000 miles (3,000 km) and add air if necessary.
• Drive carefully on roads with potholes , deep gullies or ridges.
The impact from driving through or over such obstacles can
damage your t ires. Impact with a curb may also cause damage to
your tires . •
After any impact , immediately inspect your tires or have them
inspected by the neares t authorized Audi dea ler . Replace a
damaged tire as soon as possib le.
• Inspec t you r tires every 2,000 miles (3,000 km) for damage and
wear . Damage is not always easy to see. Damage can lead to loss of
air and underin flation, which cou ld eventua lly cause tire fai lure. If
you be lieve that a tire may have been damaged , replace the tire as
soon as possible .
• These tires may wear more quickly than others.
• Please also remember that, while these tires de liver responsive
handling, they may ride less comfortably and make more noise than
other choices.
R edu ced p erform an ce in w int er/c old sea son
c ondition s
All tires are designed for c ertain purposes . The low aspect ratio,
ultra h igh performance tires origina lly instal led o n your vehic le are
intended for maximum dry and wet road performance and hand ling.
They are no t sui table for cold, snowy or icy weather conditions . If
you drive under those circumstances , you should equip your vehic le
with al l- season or winte r ti res, which offer better tract ion under
those conditions . We suggest you use the recommended snow or
all -season tires specified for your vehicle, or their equiva lent.

[ i) Tips
• In the case of an intentional loss of air pressure, for example,
when re -adjusting tire pressure, this has to be stored again after ­
wards=>
page 256.
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air tempera ture.
• The yellow symbol disappears, when the tire pressure is
correc ted and the new pressure is stored in the system=>
page 256.
• After changing a wheel or replacing a wheel with the spare tire
you have to adjust the tire pressures on all wheels. In addition , you
must then initialize the new tire pressures in the tire pressure moni ­
toring system*=>
page 257. •
Ap plies to vehicles: w ith tir e pressure monitor in g system
Storing tire pressures
Correct storage of specified pressure is the basic require ­
ment for reliable tire pressure monitoring.
Fig. 154 SET-button :
Tire pressure moni­
toring system
In order for the tire pressure monitoring system* to operate
appropriately, you have to re-save the specified pressures
whenever you adjust tire pressures, for example when the
load condition of your vehicle changes . Proceed as follows:
Correcting tire pressure
Check the pressure in the tires.
Adjust air pressure as needed to comply with the infor­ mation on the label located on the driver's side B -pillar
(vis ible when the door is open).
Saving tire pressures
Turn on the ignition.
Press the button=> fig. 154 for app roximately 5 seconds.
You will hear a beep and the symbol in the instrument
cluster flashes three times.
All pressure warning indicators in the display will be canceled.
Following each intentional change in specified pressures, tire pres­
sures must be resaved.
After the pressures are saved, the tire pressure monitoring system* measures the current tire pressures and saves them as the new
specified pressures.
[ i J Tips
• The tire pressure is shown on the tire pressure label. The tire
pressure label is located on the driver's side B-pillar (visible when
the door is open). The tire pressure label lists the recommended cold tire inflation pressures for the vehicle at its maximum capacity
weight and the tires that were on your vehicle at the time it was
manufactured . For recommended tire pressures for normal load
conditions, please see chapter
=> page 238. .,_

& WARNING (continued)
• Never drive with run-flat tires if heat build-up causes the tire to
give off smoke .
• Never drive with run-flat tires if the vehicle shakes or vibrates
severely.
• Never drive with a run-flat tire that develops sidewall cracks or
other damage while in use .
0 Note
Run-flat tires have specia l characteristics and requirements, that are
very different from conventional tires. Run-flat tires require special
rims for run-flat use and cannot be used on conventional wheel
rims.
[ i] Tips
• I f you are not able to continue driving with run -flat tires, please
seek professional assistance.
• Please contact your authorized Audi dealer or Audi of America,
Inc . if you have questions about tires and rims. •
Applies to vehic les: with Run-flat t ires
Driving with run-flat tires
Handling characteristics change when tire pressure is
low.
Driving on tires with low tire pressure changes the way a
vehicle handles, particularly when cornering and braking.
The handling characteristics of run-flat tires do not seem to
change a lot even when driving on low pressure or in the
run-flat mode. Nevertheless you must still take special
precautions when operating a vehicle on run-flat tires when
tire pressure is low or the tire(s) is flat: The
Electronic Stabilization Program (ESP) must be
switched on.
- Never drive faster than 50 mph (80 km/h)~
&-
Plan ahead when driving and anticipate what you will
have to do considering traffic and road conditions up
ahead.
- Accelerate carefully.
- Avoid unnecessary and sudden steering and braking
maneuvers.
Reduce your speed in plenty of time before intersections,
curves and other places where you may have to react
quickly.
Please see:=> page 258, "When it is not possible to continue driving,
even with run -flat tires?"
Handling characteristics change when driving with
low air pressure or with flat tires even with special run­
flat tires
A low pressure or flat front tire affects vehicle handling characteris ­
tics by pulling the vehicle slightly to the side where the tire is
mounted and reduces braking performance.
A low pressure or flat rear tire also affects driving characteristics by
pulling to the side where the tire is mounted and also reduces
braking performance. The effect on vehicle handling is most notice ­
able when driving around curves.
& WARNING
Changed vehicle handling characteristics when driving in the run­
flat mode can cause loss of vehicle control, a crash and serious personal injury. .,,,

Maintenance book let.
Und er di ffi cult ope rating cond ition s, for example at extremely low
outside temperatures, in very dusty regions, etc ., some service work
should be performed between the intervals specified. This app lies
particularly to:
• oil changes, and
• cleaning or replacing the air filter.
By regularly maintaining your vehicle, you help make sure that emis­

the environment. •
Important considerations for you and your
vehicle
The increasing use of electronics, sophisticated fuel injection and
emission control systems, and the general ly increasing technical
complexity of today's automobi les, have steadi ly reduced the scope
of maintenance and repa irs which can be carried out by vehicle
owners.
Al so, sa fety a nd e nvironment al concerns p lace very strict
limi ts on the na ture of repairs a nd adjustments to engine and trans ­
mission parts which an owner can perform.
Maintenance, adjustments and repairs usually require special tools,
testing dev ices and other equipment ava ilable to specially trained
workshop personnel in order to assure proper performance, reli ­
abil ity and safety of the vehicle and its many systems.
Improper maintenance, adjustments and repairs can impair the
ope ration and re liability of your vehic le and even void your vehic le
warranty. Therefore, proof of servicing in accordance with the main­
tenance schedu le may be a condition for upholding a pos sible
warranty claim made within the warranty period. Above all, operational safety can be adversely affected, creating
unnecessary r isks for you and your passengers .
If in doubt about any servicing, have it done by your authorized Audi
dea ler or any other properly equipped and qualified workshop. We
strongly urge you to give your authorized Audi dealer the opportu­
nity to perform all scheduled maintenance and necessary repairs.
Your dealer has the fac ilities, origina l parts and trained spec ial ists
to keep your vehicle running proper ly.
