We recommend that you use maintenance -free or cyc le- resis­
tant /leak -pr oof
batteries according to the standards TL 825 06 (from
December 1997) and VW 7 50 73 (from Augus t 2001 ).
Replacing the battery should be carried by a qualified workshop.
P lease follow the instructions on the battery cover.
0 Note
• All work on the battery requires technical knowledge. Please
contact an Audi dealership or another authorized facility for ques­
tions about the battery- danger of acid bu rns and explosion hazard!
• The battery must not be opened! Do not try to change the
battery's liquid level, otherwise detonat ing gas wil l escape from the
battery - explosion ha zard!
• The AGM battery in the luggage compartment cannot leak,
because the electrolyte for this battery is absorbed into a special
g lass mat . This leak-proof battery must not be rep lace with a
conventiona l battery .
• Make sure the ventilation hose on the side of the battery is
connected, otherwise fumes or battery acid can leak out.
• Battery holde r and terminals always have to be secured correctly .
• Before al l wo rk on the battery follow the
warning s below :::> & in
" Working on the battery" on page
232.
~ For the sake of the environment
Because of the problem of proper d isposal of a battery, we recom­
mend your authorized Audi dea ler change the battery fo r you.
Batteries contain sulfur ic acid and lead and must always be
disposed of properly in compliance with all environmental regula ­
t ions . Di sposing of vehicle batteries i mproper ly is very dangerous to
the environment. Make sure that the removed battery cannot over ­
ba lance, otherwise sulfur ic acid migh t escape!
[ i ] Tips
If your ve hic le is left standing for several weeks at extremely low
temperatures, the vehicle battery should be removed and stored
where it will no t free ze. This will preven t it from being damaged and
having to be replaced. •
Working on the battery
Be especially care ful w hen wor king o n or nea r the

& WARN ING (continued )
• Driving with underinflated tires bend more , letting them get
too hot re sulting in t read separation , sudden t ire failure and loss
of control.
• Excessive speed and /overloading can cau se heat bu ild-up ,
sudden tire failure and lo ss of control.
• If the tire pressure is too low or too high , the tires 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 che ck the tire pres sure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
va lves. To prevent this, always ma ke sure that fact ory insta lled valve
stem caps on all whee ls are securely mounted on the valve .
<£> For the sake of the environment
Underinflated tires will also increase the fue l consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle and
any tire can carry. A vehicle that is overloaded will not handle well
and is more difficu lt to stop. Overload ing can not only lead to loss
of vehicle contro l, but can a lso damage important parts of the
veh ic le an d ca n lead to sudden t ire fa ilu re , inc lud ing a bl owout a nd
sudden deflation that can cause the vehicle to crash.
Yo ur saf ety a nd that of you r passenge rs also de pends on making
sure that load limits are not exceeded . Vehicle load includes every ­
body and eve ryt hing in and on the vehic le . Th ese load limi ts are technica
lly referred to as the vehicle's
Gross Vehicle We ight Rating
("GVWR").
Th e "GVWR" includes the weight of the basic vehicle, all factory
insta lled accessories, a ful l tank of fuel, oil, coolant and other f luids
p lus max imum load. The ma ximu m load inc ludes the numbe r of
passengers that the vehicle is intended to carry ("seating capacity")
w it h an assu med we ight o f 150 lbs (68 kg) for eac h pass enger at a
designated seating position and the total weight of any luggage in
t he vehicle.
T he
Gross Axle Weight Rating ("GAWR"l is the maximum load that
can be a pplied a t eac h of the vehic le's two a xles .
T he Gross Veh icle Weigh t Rat ing a nd the Gross A xle We igh t R ating
are listed on the safety comp liance stic ker label located on the
dr iver's s ide B -p illar . You r Aud i has 2 sea ting pos it io n s. Eac h seating
posit ion has a safety belt=>
page 137, "Safety belts".
T he fact that the re is a n up per lim it to yo ur vehicle's G ross Veh ic le

ca rried in the ve hicle is lim ited. The mo re pas se ngers in the vehic le
or passe ngers w ho ar e heav ier t han th e sta ndard weights assumed
mean that less weight can be carried as luggage.

& WARNING
Overloading a vehicle can cause loss of vehicle control , a crash or
other accident, serious personal injury , and even death .
• Carrying more weight than your vehicle was des igned to carry
will prevent the vehicle from handling properly and increase the risk of the loss of vehi cle control .
• The brakes on a vehicle that has been overloaded may not be
able to stop the vehicle within a safe distance. .,_

Wheel bolts
W heel b olts mus t al wa ys be tigh te n ed to t he cor rect
to rqu e.
The design of wheel bolts is matched to the factory instal led rims . If
d ifferen t rims are fitted, the co rrect w heel bo lts wit h th e rig ht length
and correctly shaped bolt heads m ust be used. This ensures that
w hee ls are fitt ed s ecure ly a nd th at t he brake sys te m funct ions
correctly .
I n certain circums tances, yo u may no t use w heel b olts fr om a
differ ent vehicle -even if it is the same model::::;,
page 296.
&_ WARNING
Improperly tightened or maintained wheel bolts can become loose
causing loss of control , a collision and serious personal injury.
• Always keep the wheel bolts and the threads in the wheel hubs
clean so the wheel bolts can turn easily and be properly tightened.
• Never grease or oil the wheel bolts and the threads in the wheel
hubs. They can become loose while driving if greased or oiled,
even if tightened to the specified torque .
• Only use wheel bolts that belong to the rim being installed.
• Never use different wheels bolts on your vehicle.
• Always maintain the correct tightening torque for the wheel
bolts to reduce the risk of a wheel loss. If the tightening torque of
the wheel bolts is too low , they can loosen and come out when the
vehicle is moving . If the tightening torque is too high, the wheel
bolts and th reads can be damaged and the wheel can become
loose .
0 Note
The specified torque for the wheel bolts is 90 ft lb (120 Nm) with a
t ole ranc e of ± 7,4 ft lb(± 1 0 Nm). To rque whee l bolts diag onally.
After changing a wheel, the torque must be checked as soon as possible with a to
rque wrench -preferab ly by an authorized Audi
dea ler o r qu alif ied wo rksh op.•
Low aspect ratio tires
Yo ur Audi is fac tory-equip ped wi th l ow asp ect rati o tires. Th ese tires
have been thorough ly tested and been selected specifically for your
mod el for thei r su per b p erfo rma nce, road feel an d handl in g u nder
a variety of driving conditions . Ask your author ized Aud i dea ler for
mo re deta ils.
T he low aspec t ra tio o f th ese t ires is ind icate d by a numera l o f 55 or
less in the t ire's size designation. The numera l represents the ratio
of the ti re's s idewa ll height in re la ti on to its tread w idth e xpress ed
in percentage. Conventiona l tires have a height/width ratio of 60 or
mo re .
The performan ce of low -aspect -ratio t ires is part icularly sensitive to
improper inflation pressure . It is therefore important that low
aspect ratio tires are inflated to the specified pressure and that the
inflation pressure is regularly checked and maintained. Tire pres­
sures should be checked at least once a month and alway s before a
long trip::::;,
page 244, "Checking tire p ressure".
What you can do to a void tire and rim damage
L ow a spect ratio tires can be damaged more easi ly by impact with
potho les, curbs, gull ies or ridges on the road, particularly if the t ire
is underinflated.
In orde r to minimi ze the occurrence o f im pact da mage to th e tire s
of your vehicle, we recommend that you observe the fo llowing
p reca utions:
• Always ma intain reco mm ende d inflat io n pressu res . C heck your
tire p ressure every 2, 000 miles (3 ,000 km) and add ai r if neces sary .
• D rive car eful ly on roads with potholes, deep gullies or ridges.
Th e impact from d riving th ro ugh o r ove r such o bstac les can
dama ge you r tires . Impact w ith a curb may also cause da mage to
your tires . .,_

Taking the wheel off
Follow these instructions step-by-step for changing the
wheel.
Fig . 176 Wheel
change : using the
screwdriver handle
(with the blade
removed) to turn the
bolts
Fig. 177 Wheel
change : alignment pin
inside the top hole
After you have loosened all wheel bolts and raised the
vehicle off the ground, perform the following steps to
remove and replace the wheel:
Removing the wheel Use the hexagonal socket in the screwdriver handle to
completely turn out the topmost wheel bolt and set it
as ide on a
clean surface => fig. 176. ~

What do I do now? -
----------------
•
-Screw the threaded end of the alignment pin from the
tool kit hand-tight into the now vacant bolt hole
=:> page 270, fig. 177.
- Then completely unscrew the other wheel bolts as
described above.
- Take off the wheel leaving the alignment pin in the bolt
hole.
Putting on the wheel
- Lift the spare wheel and carefully slide it over the align­
ment pin to guide it in place.
- Use the hexagonal socket in the screwdriver handle to
screw in and tighten all wheel bolts slightly.
- Unscrew the alignment pin and insert and tighten the
remaining wheel bolt slightly like the rest.
- Turn the jack handle counter -clockwise to lower the
vehicle until the jack is fully released.
- Use the wheel bolt wrench to tighten all wheel bolts
firmly =:> page 268. Tighten them crosswise, from one
bolt to the (approximately) opposite one, to keep the
wheel centered.
[ i J Tips
Never use the hexagonal socket in the handle of the screwdriver to
loosen or tighten the wheel bolts.
• Pull the reversible blade from the screwdriver before you use the
hexagonal socket in the handle to turn the wheel bolts.
• When mounting tires with
unidirectional tread design make sure
the tread pattern is pointed the right way~
page 272.
• The wheel bolts should be clean and easy to turn. Check for dirt
and corrosion on the mating surfaces of both the wheel and the
hub . Remove all dirt from these surfaces before remounting the
wheel. •
Notes on wheel change
Please read the information~ page 249, "New tires and replacing
tires and wheels", if you are going to use a spare tire which is
different from the tires on your vehicle.
After you change a tire:
• Check the tire pressure on the spare immediately after
mounting.
• Have the wheel bolt tightening torque checked with a torque
wrench as soon as possible by your authorized Audi dealer or a qualified service station .
• With steel and alloy wheel rims, the wheel bolts are correctly
tightened at a torque of 90 ft lb (120 Nml.
• If you notice while changing a tire that the wheel bolts are
corroded and difficult to turn, then they should be replaced before
you check the tightening torque.
• Replace the flat tire with a new one and have it installed on your
vehicle as soon as possible. Remount the wheel cover.
Until then, drive with extra care and at reduced speeds.
& WARNING
• If you are going to equip your vehicle with tires or rims which
differ from those which were factory installed, then be sure to read
the information
~ page 249, "New tires and replacing tires and
wheels".
• Always store the tools securely in luggage compartment.
Otherwise, in an accident or sudden maneuver they could fly
forward, causing injury to passengers in the vehicle.
