The correct tire pressure for the spare wheel i s
located on a label on the driver's side 8-pillar.
Because technical changes may be made to
ve hicle equipment during the model year, al­
ways compare the tire size designation on the
tire pressure labe l on your vehicle w ith the
tires on your vehicle. Make sure that the tire
size information on the veh icle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be­
lo ngs to someone else or you bought the veh i- cle
with different rims/tires or you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas ­
sengers also depends on making sure that
l oad lim its are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle. These load limits are techn ically refer­
red to as the veh icle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at eac h of the vehicle's two axles .
T he Gross Vehicle Weight Rating and the .,.

Gross Axle Weight Rating are listed on the
safety compliance sticker label located on the
driver's side B-pi llar . The tire pressure label on
your Aud i lists the maximum combined
weight of all of the occupants and luggage or
other cargo that the vehicle can carry . For the
locat io n of the tire pressure label¢
fig. 182 .
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a cras h or other accident, se­
r ious personal inj ury, and eve n death.
- Carry ing more weight than yo ur vehicle
was designed to ca rry will p revent the
vehicle from hand ling properly and in­
crease the risk of a loss of veh icle con ­
t ro l.
- T he bra kes on a veh icle that has bee n
overloaded may no t be a ble to stop the
vehicle within a safe distance .
- T ires on a vehicle that has been overload ­
ed can fail suddenly causing loss of con­
tro l and a crash.
- Always make sure that the tota l load be ­
ing transported - including the weight of
a trai le r hitch and the tongue weight of a
loaded trailer -does not make the veh i­
cle heav ier than the veh icle's Gross Vehi­
cle Weight Rating .
A WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious o r fatal acci­
dent .
- Incorrect tire pressures and/or underin­
flation cause increased tire wea r and can
affect the handli ng of the vehicle.
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowo ut and sudde n de­
fla tion, causing loss of vehicle control.

Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure label located on driver's side 8-pil­
lar.
The recommended tire pressures are on the
ti re pressu re label and in the table
¢ page 231, Cold tire inflation pressure.This
mea ns tha t the pressu re m ust be chec ked and
adjus ted when the t ire has not been dr iven fo r
more than a couple of miles (kilometers) a t
low speeds d uring the previous three ho urs.
Air in the tires expands when the tire heats up
as a result of interna l frict ion as it flexes in
u se. The tire pressure is higher when the tire
has warmed up than whe n it is "cold ."
It is the inflation pressure in a "co ld" t ire that
counts. Therefore, you should never let a ir o ut
of a warm tire to match "Cold t ire inflat ion
pressure" recomme ndat io ns¢
page 231 . The
ti res wou ld then be unde rinflated and could
fail suddenly .
The t ire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
max imum capac ity for the new, orig inal
equipment tires that were on your ve hicle at
the time it was ma nufactu red. For the lo ca­
t ion of the labe l
¢fig. 182.
Most tires lose air natura lly ove r time . They
can a lso lose some air if you d rive over a pot­
hole or hit a curb while par king.
It is usually
not po ss ible to see whethe r the rad ia l t ires
u sed today are underinflated just by loo king
at them .
T he refore, be sure to check t ire p ress ures at
l east once a mo nth and a lways befo re goi ng
on a long t rip. M ake s ure to ta ke the n umber
of peop le and the amount o f luggage into ac ­
count when adjusting tire pressure for a trip -
even one that yo u wou ld not conside r to be
"long." See ¢
page 2 3 5, Tires and vehicle
load limits
for mo re important information .
A lways use an acc urate tire pressure ga uge
when checking and ad justing inflation pres­
s u res. Check a ll of the tires and be sure not to ..,. •

234 Tire s and wheel s
forget the spare tire. If the pressure in any tire
is too h igh when the tire is "cold", let air out
of the tire slowly with the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is correct for the
load (passengers and luggage) and kind of
driving you plan to do .
If the pressure in any tire is too low, note the
d ifference between the pressure in the cold
tire and the pressure you need and add the a ir
that you need to reach the correct pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as listed on the on
your veh icle and in this manua l and the kind
of dr iving you p lan to do .
Never exceed th e ma ximum inflati on pres­
s ur e list e d on th e tir e s idewall f or an y re a ­
so n.
Remembe r that the vehicle manufacturer, not
the tire manufactu rer , determ ines the correct
tire pressure for the t ires on your vehicle .
It is important to check the tire pressure when
the tires a re cold .
- Read the requ ired t ire pre ssure from the tire
pressure label. The tire pressure label is lo­
cated on the driver's side 8 -p ill ar . The tire
pressure label lists the recommended cold
t ire inflat ion pressures for the vehicle at its
maximum capacity we ight a nd the tires that
were on yo ur vehicle at the time it was man­
u factured. Fo r recommended tire press ures
for normal load conditions, please see chap ­
ter
¢ page 231 .
-Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve.
- The tire pressures should only be chec ked
and adjus ted when the tires are cold . The
s li ghtly raised pressures of warm tires must
not be reduced .
- Adjust the tire pressure to the load you are
carrying .
- Re insta ll the va lve stem cap o n the valve .
When should I check th e tir e pre ssure ?
The correct tire pressu re is especially impor­
tant at high speeds. The pressu re should
therefore be checked at least once a month
and always before starting a jo urney . Do not
forget to check the tire pressure for the spare
wheel.
When should I adju st the ti re pre ssures?
Adjust the tire pressure to the load you are
carrying . After changing a whee l
or replacing
whee ls you have to adjust the tir e pressur es
on all wheels. In addition, you m ust then initi­
a lize the new tire pressures in the t ire pres­
sure monitoring system*¢
page 245.
A WARNING
-Incorrect tire pressures and/or underinfla-
tion can lead sudden tire fa ilure, loss of
control, collision, se rious pe rsonal injury
or even dea th.
- When the
[IJ wa rning symbol appears in
the instrument cluster, stop and inspect
the t ires.
- Inco rrect tire pressure and/or underinfla­
tion can cause increased tire wea r and
can affect the handling of the vehicle and
stopping abi lity.
- Incorrec t tire pressures and/or underin­
flation can a lso lead to s udden t ire fail ­
ure, including a blowout and sudden de­
flation, ca using loss of vehicle contro l.
- The driver is responsible for the correct
tire pressures for all tires on the vehicle .
The applicable pressure values are locat ­
ed on a sticker on the dr iver's s ide 8-pil­
lar.
- Only when all tires on the vehicle are fil­
led to the correct pressure, the t ire pres­
sure mon itor ing system* can work cor­
rectly .
- The use of incorrect tire pressure values
can lead to acc idents or other damage .
Therefore it is essential that the drive r
observe the spec ified t ire pressu re val ues
for the tires and the correct pressures for
II),

th e f unct ion of the tire pressure monitor­
ing system*.
- Always inflate tires to the recommended
and correct tire pressure before driving
off.
- Driving with under inflated tires bend
more, letting them get too hot resu lting
in tread separation, sudden t ire failure
and loss of control.
- Excessive speed and/overloading can
cause heat build-up, sudden tire fail ure
and loss of control.
- If the t ire pressure is too low or too high,
the tires w ill wea r prematurely and the
vehicle will not hand le we ll.
- If the t i re is not flat and you do not have
to change a w heel immed iate ly, dr ive at
reduced speed to the nearest serv ice sta­
t ion to check the tire pressure and add
air as requi red.

Tires and vehicle load limits
There are l imits to the amo un t of load or
weight that any vehicle and any tire can carry .
A veh icle that is overloaded w ill not handle
w ell and is more difficult to stop. Overload ing
can not only lead to loss of vehicle contro l,
but c an a lso damage import ant parts of the
ve hicle and can lead to sudden tire failure, in­
cluding a blowout and sudden deflation that
can cause the ve hicle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are n ot exceeded. Vehicle load includes everybody
and everyth ing in and on the vehicle . Th ese
Tire s an d wheel s 235
load lim its are technically referred to as the
vehicle's
Gross Vehicle Weight Rating
("GVWR").
T he "GVWR" incl udes the weight of the basic
vehicle, a ll factory installed accessories, a f ull
tan k of fuel, oi l, coo lant and other fluids plus
max imum load. The max imum load incl udes
the n umber of passengers t hat the vehicle is
intended to carry ("seat ing capac ity") with an
ass umed we ight of 150 lbs . (68 kg) for eac h
passenger at a designated seating posi tion
and the tota l weight of a ny luggage i n the ve­
hicle. If you tow a tra ile r, the we igh t of the
tra iler hi tch and the tongue we igh t of t he
loaded tra iler mus t be included as part of the
vehicle load .
T he
Gro ss Axle Weight Rating (" G AWR ") is
the max imum load th at can be appl ied a t each
of the veh icle's two axles .
T he Gross Vehicle Weight Rat ing and t he
G ross Ax le Weig ht Ra ting are listed on the
sa fe ty comp lian ce sti cke r la bel lo cate d on the
driver's side B-pillar. Audi has
4 seating pos i­
tions, 2 in the front an d 2 in the rear fo r total
seating capacity of 4 . Eac h seati ng position
has a seat belt
q page 132, Safety belts.
T he fac t that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­ ried in the vehicle ( includ ing the weight of a
trailer hitch and the tongue weight of the
loaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers w ho are
heavier than the sta ndard we ights assumed
mea n that less we ight can be ca rried as lug­
gage.

236 Tires and wheels
-Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
vehicle within a safe distance.
- Tires on a vehicle that has been overload­
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total load be­
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer - does not make the vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi­
cle's placard (tire inflation pressure label)
¢fig. 182.
2. Determine the combined weight of the driver and pas- sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and pas­sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢fig. 182.
4. The resulting figure equals the available amount of car­
go and luggage load capaci­
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five 150
lbs. passengers in your vehi­
cle, the amount of available
cargo and luggage load ca­
pacity is 650 lbs. (1400-7 SO
(5
X 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely exceed the available cargo
and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­ duces the available cargo

and luggag e load c apaci ty of
y our vehicle.
.,. Check the tire sidewall
(c:::> fig . 18 6) to d etermine th e
de sign ated load rating f or a
s p ecific tir e.
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balan cing , correc t tire pressure and driv­

Rotating tires for more even w ear
For all four tires on your vehicle to have the
same service life , we recommend that the
front and rear t ires a re rotated a ccording to
the tire man ufactur er's suggested tire ro ta­
tion intervals . Please remember the follow­
ing:
- Tire rotation in tervals may differ from the
veh icle servi ce inte rv al s o utli ned in your
Ma intenance and Warranty Boo klet.
- The longer one tire is used in one lo cation
on t he veh icle, the more it wears a t cer tain
points ; the re fore, we recommend that you
follow the tire man ufact urer's suggested
tire rotation intervals .
- Vehi cles w ith front-wheel dr ive experience
more tread wear on the front wheels com­
pared to a ll wheel drive (quattro ®).
- Please rotate tires as shown¢

anced, resulting in vib rat ions you ca n usually
feel through the steer ing whee l.
Un balanced wheels must be rebalanced to
avo id excessive wear on steering, s uspension
and t ires. A whee l m ust also be reba lanced
when a new tire is insta lled .
Incorrect wheel alignment
Incor rect wheel alignment can cause exc es­
s ive tire wear, impa iring the safe ty of the vehi-
cle. If tires show excessive wear, have the

wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All wheel dri ve
Vehicles w ith quattro ® must always have tires
of the same size, construction and tread type. F or detai ls see

.8, WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a veh icle when the tread on
any tire is worn down to the wear indica­
tors.
- Worn tires are a safety hazard, they do not grip well on wet roads and increase
your risk of "hydrop lan ing" 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 histo­
ry." Old used tires may have been dam­
aged even though the damage cannot be
seen that can lead to s udden tire failure
and loss of vehicle control.
New tires and replacing tires and wheels
New tires and wheels have to be broken in .
