than a total of 0.5 qt/liter engine oil that does not conform to Audi
oi l specification VW 502 00.
For more information about engine oi l that has been approved for
your vehicle, please contact e ither your authorized Audi dealer or
Aud i Custo mer Relations at 1 (800) 822 -2834 or visit our web site at
www.audiusa.com or www.audicanada.ca. Here you will a lso find a
current list of o ils (manufacture rs, brand names etc.) that con form
to Audi oi l standard VW 502 00.
Changing the engine oil
The engine oil and oil fil ter must be changed according to the
mi leage (kilometers) and time intervals specified in your vehicle's
Warranty & Maintenance booklet. Do not exceed these intervals -
harmful deposits from old engine oil can reduce engine perfor­
mance a nd can lead to expens ive eng ine repairs.
Changing the oil at the recommended intervals is so very important because the lubricating properties of oi l decrease gradual ly during
normal vehicle use. If you are not sure when you have your oil
changed, ask your authorized Audi Service Adviso r.
Under some circumstances the engine oil should even be changed more frequently . Change oil more often if you drive mostly short
distances, ope rate the vehicle in dusty areas or m ostly under stop ­
and -go traffic cond itions, or when you use your vehicle where
temperatu res stay below freezing point for long per iods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not
a reason to change the oi l more o ften than recommended.
Dam age or malfunctions d ue to la ck of ma inten ance
It is essential that you change your oi l a t the recommended in terva ls
using on ly engine oil that complies with Audi oil standard
VW 502 00. Your Limited New Vehicle Warranty does not cover
damag e or ma lfunctions due to failure to follow recommended
maintenance and use requirements as set forth in the Audi Owner's
Manual and War ranty & Mai ntenance booklet. Your dealer wi ll have
to deny warranty coverage unless you present to the dealer proof in the form of Service or Repair Orders that all schedu
led maintenance
was performed in a timely manner. •
Engine oil consumption
The e ngine in your vehicle depends on an adequate
amount o f oil to lubricate and cool all of its moving parts.
In order to provide effective lubrica tion and coo ling of in terna l
engine components, all interna l combustion engines consume a
cer tain amoun t of oil. Oi l consump tion varies from e ngine to engine
and may change significantly over the life of the engine. Typical ly,
engi nes w ith a specified break -in p eriod (see =>
page 243) consume
more o il during the break- in period than they consume after oil
consump tion has stabi lized .
Under normal conditions, the ra te of oil consumpt ion depends on
the quality and viscosity of the oil, the R PM (revolutions per minute)
at which the engine is operated, the ambient temperature and road
conditions. Further factors are the amount of oil di lution from water
con densa tion or fue l residue and the oxi dation leve l of t he oi l. As
any engine is subject to wear as mileage builds up, the oil consump ­
tion may increase over time until replacemen t of wo rn components
may become necessary.
With all these variables coming into play, no standard rate of oi l
consumptio n can be establ ished o r speci fied. There is no alternat ive
to regular and frequent checking of the oil level, see
Note .
If the yel low engine oil l evel warn ing sy mbol in t he instrumen t
cluster ._ lights up, you should check the oil level as soon as
p ossible :::::>

Carefully top off with the appropriate oil in 0.5 liter doses.
- Screw the cap back on the filling hole and close the
engine hood.
- Check the oil level again after two minutes=>
page 275.
-Top off the oil again, if necessary.
& WARNING
• While topping off, the oil must not come in contact with hot
engine parts -fire hazard!
• The oil filler cap must be properly secured to prevent oil from
being sprayed on the hot engine and exhaust system when the
engine is running -fire hazard!
• If your skin has come in contact with the engine oil, you must
subsequently cleanse it thoroughly.
0 Note
• Check the oil level using the radio or MMI*. If the message Please
reduce oil level appears, contact your authorized Audi dealer or
other qualified workshop to have excess oil extracted if necessary.
• Audi does not recommend the use of oil additives. They may
damage the engine and adversely affect your New Vehicle Warranty.
'i> For the sake of the environment
• Under no circumstances can the oil come in contact with the
sewage network or the soil.
• Observe and follow legal regulations when disposing of empty
oil containers. •
Changing the engine oil
We recommend that have your oil changed by an autho­
rized Audi dealer or a qualified service station.
Before you check anything in the engine compartment, always read
and heed all WARNINGS=>
& in "Working in the engine compart­
ment" on
page 271.
The engine oil must be changed according to the intervals specified
in your Warranty
& Maintenance booklet. This is very important
because the lubricating properties of oil diminish gradually during
normal vehicle use.
Under some circumstances the engine oil should be changed more
frequently. Change oil more often if you drive mostly short
distances, operate the vehicle in dusty areas or under predomi­
nantly stop-and-go traffic conditions, or have your vehicle where
temperatures remain below freezing for extended periods.
Detergent additives in the oil will make fresh oil look dark after the
engine has been running for a short time. This is normal and is not
a reason to change the oil more often than recommended.
Because of the problem of proper disposal, along with the special
tools and necessary expertise required, we strongly recommend
that you have your oil changed by an authorized Audi dealer or a
qualified service station .
If you choose to change your oil yourself, please note the following
important information:
& WARNING
To reduce the risk of personal injury if you must change the engine
oil in your vehicle yourself:
• Wear eye protection.
• To reduce the risk of burns from hot engine oil, let the engine
cool down to the touch.

•
& WARNING (continued)
• When removing the oil drain plug with your fingers, stay as far
away as possible. Always keep your forearm parallel to the ground
to help prevent hot oil from running down your arm.
• Drain the oil into a container designed for this purpose, one
large enough to hold at least the total amount of oil
in your engine.
• Engine oil is poisonous. Keep it well out of the reach of children.
• Continuous contact with used engine oil is harmful to your
skin. Always protect your skin by washing oil off thoroughly with
soap and water.
0 Note
Never mix oil additives with your engine oil. These additives can
damage your engine and adversely affect your Audi Limited New
Vehicle Warranty.
<£> For the sake of the environment
• Before changing your oil, first make sure you know where you
can properly dispose of the used oil.
• Always dispose of used engine oil properly. Do not dump it on
garden soil, wooded areas, into open streams or down sewage
drains.
• Recycle used engine oil by taking it to a used engine oil collec­
tion facility in your area, or contact a service station. •
Engine cooling system
Coolant
The engine coolant performs two functions: it keeps the
engine from overheating and it protects the engine from
freezing in the winter.
The cooling system is sealed and generally requires little attention.
The cooling system has been filled at the factory with a permanent
coolant which does not need to be changed. The coolant consists of
a mixture of water and the manufacturer's glycol -basedcoolant
additive G12++ antifreeze with anti corrosion additives (50% for USA
models; 60% for Canadian models). This mixture both assures the
necessary frost protection and protects metal components in the
engine's cooling system from corrosion and scaling. It also raises
the boiling point of the coolant.
Do not reduce the concentration of the coolant in the summer by
adding plain water.
The proportion of coolant additive must be at
least 50% but not more than 60%
to maintain antifree ze protection
and cooling efficiency. If the coolant frost protection is too low, the
coolant could freeze and damage the vehicle heating and engine
cooling system.
For year-round driving, antifreeze is added at the factory for temper­
atures down to:
• -31 °F
! -35 °ci usA
• - 40°F ( - 40°CJ Canada.
You can mix the G12++ coolant additive with other additives (G12 +
or G12) . Always check with your authorized Audi dealer .

Vehicle care I t •

-~_C_ h_e _c _ k_ i_n ...:::g::;...._ a_n_ d_ f_ i_ll _in -'g:::;.._ ___________________________________________ _
Have the battery checked when you take your vehicle in for service.
You are well advised to replace a battery that is older than 5 years.
With certain types of airbag deployment, the battery is discon­ nected from the vehicle electrical system for safety reasons=>
& in
"Repair, care and disposal of the airbags" on
page 202.
Disconnecting the battery terminals
Some vehicle functions (power window 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 electr ical system when absolute ly necessary for repairs .
Vehicles not driven for long periods
If you do not drive your vehicle over a period of several days or
weeks, electrical components are gradually cut back or switched off.
This reduces energy consumption and maintains starting capability
over a longer period=>
page 241.
Take into consideration that when you unlock your vehicle, some
convenience functions, such as the master key remote function or power seat adjustment, may not be available. The convenience
functions will be available again when you turn on the ignition and start the engine .
Winter operation
During the winter months, battery capacity tends to decrease as
temperatures drop . This is because more power is also consumed
while starting, and the headlights, rear window defogger, etc., are
used more often.
Avoid unnecessary power consumption, particularly in city traffic or
when traveling only short distances . Let your authorized Audi dea ler
check the capacity of the vehicle battery before winter sets in
=>
page 284 . A well charged battery will not only prevent starting
problems when the weather is cold, but will also last longer.
[ i ] Tips
If your vehicle is left standing for several weeks at extremely low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. This will prevent it from being damaged and
having to be replaced. •
Working on the battery
Be especially careful when working on or near the battery.
The battery is located in the luggage compartment under
the floor. Before you check anything in the luggage
compartment,
read and heed all WARNINGS =:>& .
Always heed the safety warnings, when working on the vehicle
battery or the vehicle electrical system to prevent injury.
The following WARNINGS are very important when
working on the battery:
Always heed the following WARNING SYMBOLS and safety pre­
cautions when working on the battery.
Always wear eye protection .
Battery acid contains sulfuric acid. Always wear
gloves and eye protection.

& WARNING (continu ed )
• Incorrect tire pressure and /or under inflation can cause
in creased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect t ire pressures and /o r underinflat ion can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing lo ss of vehicle control .
• The driver is respon sible for the correct tire pressures for all
tires on the vehicle. The applicable pre ssure values are located on
a sticker on the driver 's side 8-pillar or on the inside of the fuel
filler flap .
• Only when all tires on the vehicle are filled to the correct pres ­
sure , the tire pressure monitoring system * can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is essential that the driver observe
the specified tire pressure value s for the tires and the correct pres ­
sures for the function of the tire pressure monitoring system *.
• Always inflate tires to the re commended and correct tire pres ­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot resulting in tread separation , sudden tire failure and loss
of control.
• Ex cessive speed and /overloading can cause heat build-up ,
s udden tire failure and lo ss of control .
• If the tire pres sure is too low or too high , the t ires will wear
prematurely and the vehicle will not handle well .
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service station
to check the t ire pressure and add air as required.

& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury !
• Never drive a vehicle when the tread on any tire is worn down
to the wear indicators.
• Worn tires are a safety hazard , they do not grip well on wet
roads and in crease your risk of "hydroplaning " and loss of control.
• Always keep chemicals that can cause tire damage , such as
grease, oil, gasoline and brake fluid away from tires .
• 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 . •

U.S. DOT Tire Identification Number (TIN ) and tire
manufacture date
T his is the tire's "seria l number". It begins with the letters "DOT"
and indicates that the tire meets all federal standards. The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac ­
ture. For example, the numbers 2209 mean that the tire was
produced in the 22nd 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.
Audi Original tire
Tires with the identification "AO" or "RO" have been specially
matched with your Audi. We recommend using only these tires
because they meet the highest standards regarding safety and
driving characteristics when used correctly. Your authorized Audi
dealer will gladly prov ide you with more information.
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 materia ls 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 qual ity grading for treadwear , traction, and
temperature resistance
Tread wear, traction and temperature grades=> page 303.
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 vehic le, make sure the
new rims also have these sensors. The sensors must be compatible
with the tire pressure monitoring system* on your vehic le.
If you instal l rims, which do not have the sensors, or have sensors
which are not compatible, then the tire pressure monitoring
system* wil l 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 secure ly mounted. We
recommend using factory instal led valve stem caps. Ask your autho ­
rized Audi dea ler to replace lost valve stem caps.
The installation of replacement tires with steel cord body p lies 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 vehic le. 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 system*, or some component of the
t ire pressure monitoring system* may be damaged. .._

•
• Never drive without the valve stem cap. The valves could get
damaged.
• If the sensors must be replaced, then the valve must also be
replaced at the same time.
For the sake of the environment
Dispose of old tires in accordance with the local requirements. •
Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C
Quality grades can be found where applicable on the tire side wall
between tread shoulder and maximum section width~
page 299,
fig. 233.
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. •
