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. ...,

When instal ling the battery, make sure the ignition and all electrica l
consumers are switched off~
0.
We recommend that you use maintenance -free or c yc le-re sis­
tant/leak -proof
batteries according to the standards TL 825 06 (from
December 1997) and VW 7 50 73 (from August 2001 ) .
Rep lacing the battery should be carried by a qualified workshop .
Please follow the instruct ions on the battery cover.
0 Note
• All work on the battery requ ires technical knowledge . Please
contact an Audi dealership or another authorized facility for ques ­
t ions about the battery -dange r of acid burns and explosion hazard!
• T he battery must not be opened! Do not try to change the
battery 's liquid level, otherwise detona ting gas will escape from the
battery -explosion hazard I
• The AGM battery in the luggage compartmen t cannot lea k,
because the electrolyte for this battery is absorbed into a special
glass mat. Th is leak -proof battery must not be replace with a
conventional battery .
• Make sure the ventilation hose on the side of the battery is
connected, otherwise fumes or battery acid can leak out.
• Battery holder and term inals a lways have to be secured correctly.
• Before all work on the battery follow the
warnings below ~ & in
"Wor king on the battery" on
page 229 .
ci' For the sake of the environment
Because of the proble m of proper d isposal of a battery, we recom ­
mend your authorized Audi dealer change the battery for you.
Batteries contain sul furic acid and lead and m ust always be
disposed of properly in compliance with all environmenta l regula ­
t ions. Disposing of vehic le batteries improperly is ve ry dangerous to
the environment . Make sure that the removed battery cannot over­
balance, otherwise su lfur ic ac id might escape!
[ i ] Tip s
If your vehic le is left standing for severa l weeks at extreme ly low
temperatures, the vehicle battery should be removed and stored
where it will not freeze. Th is will prevent it from being damaged and
having to be replaced .•

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

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. .,_
