-Never mount used tires on yo ur vehicle if
yo u 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 sudden tire failure
and loss of vehicle control.
- If you notice unusual vibration or if the
vehicle pulls to one side when d riving, al
ways stop as soon as it is safe to do so
and check the wheels and tires for dam
age .

was manufactured, and the last four numbers
represent the week and year of manufacture.
For example,
DOT ... 2212 ...
means that the tire was produced in the 22nd

p ill ar
Tire pressure genera lly refers to the amount
of air in a t ire that it needs it to do its job and
safely carry the combined load of the entire
vehicle and its contents . Tire pressure is
measured in kilopasca ls (kPa), the i nterna·
tional measur ing unit and in pou nds pe r
squa re inc h (PSI). Tire pressure is based in
par t on the vehicle's desig n and load limit -
the greatest amoun t of weight that the vehi·
cle can carry safe ly and the t ire size . The prop·
er tire pressure is freq uently referred to as the
" recommended cold tire inf lation pressure."
A ir in the tires expands when the tire heats up
because of internal frict ion when it flexes in
use . The t ire p ressu re is higher when the tire
h as wa rmed up tha n when it is "cold ." It is the
in flat io n pressu re i n a "cold" tire that counts.
Th erefore, you shou ld neve r let air ou t of a
warm tire to match " co ld tire inflat ion pres
sure" recommendations . The t ires wo uld then
be underinflated and could fail su ddenly .
M ain taining p roper t ire pr essu re is one of the
most im po rt an t th ings you ca n d o to he lp
avoid sudden tire failure. Underin fla ted t ires

A WARNING
Overloading a vehicle can cause loss of ve
hicle control, a crash or other accident, se
rious personal injury, and even death .
- Carrying more weight than your vehicle
was designed to carry will prevent the
vehicle from handling properly and in crease the risk of a loss of veh icle 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 causing loss of con
trol and a crash .
- Always make sure that the total load be
ing transported -including the we ight of
a tra iler 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 handling of the vehicle .
- Incorrect tire pressures and/or underin
flation can also lead to sudden tire fa il
ure, including a blowo ut and sudden de
flation, causing loss of vehicle control.
Checking tire pressure
-
The correct tire pressure for the tires originol
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
tire pressure labe l and in the tab le
c:::> page 252, Cold tire inflation pressure .This
means that the pressure must be checked and
adjusted when the tire has not been driven for more than a couple of m iles (k ilometers) at
low speeds during the p revious three hours . Air in the tires expands when the tire heats up
as a result of interna l friction as it flexes in
u se . The tire pressure is h igher when the tire
has warmed up than when it is "cold."
It is the inflation pressure in a "co ld" tire that
counts . Therefore, you should never let air out
of a warm tire to match "Cold t ire inflat ion
pressure" recommendat ions
c:::> page 252 . The
t ires wou ld then be underinflated and could
fail suddenly .
The tire pressure label on your Audi lists the recommended co ld tire inflation pressures at
maximum capacity for the new, orig inal
equipment tires that were on your vehicle at
the time it was manufactured . Fo r the loca
t ion of the labe l
c:::>page 252, fig . 203 .
Most tires lose air naturally over t ime . They
can a lso lose some air if you drive over a pot
hole or hit a curb while park ing. It is usually
not possible to see whether the rad ia l tires
used today are underinflated jus t by looki ng
at them.
T he refo re, be sure to check t ire p ressures at
least once a month and always before going
o n a long trip. Ma ke sure to take the numbe r
of peop le and the amou nt o f luggage into ac
count when adjust ing tire pressu re for a trip -
even one that yo u wo uld not consider to be
" long." See
c:::> page 256, Tires and vehicle
load limits
for more important information .
Always use an ac curate tire p ress ure ga uge
when checking and adj usting inflation pres
s u res . Check a ll of the tires and be sure not to
forget the spare tire. If the pressure in any t ire
is too high when the tire is "cold," let air out
of the tire s low ly w ith the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is co rrect fo r the
load (passengers and luggage) and k ind of
dr iv ing you plan to do.
If the pressure in any tire is too low, note the
difference between the p ressure in the co ld
t ire and the pressure you need and add the air
t h at you need to reach the cor rect pressure for
t h e ve hicl e load (passengers and luggage) for
the tires on your vehicle as listed on the on

Remembe r that the vehicle manufacturer, not
the t ire manufacturer , determ ines the co rrect
tire pressure for the t ires on your veh icle .
It is important to check the tire pressure when
the t ires are cold .
- Read the requ ired tire pressure from the tire
pressure label. The tire pressure label is lo
cated on the driver's side 8-p illar. The tire
pressure label lists the recommended cold
t ire inflat ion p ressu res for the veh icle at its
maximum capacity we ight and the tires that
were on yo ur vehicle at the time it was man
ufact ured. For recommended tire pressures
for normal load condit ions, please see chap
ter
¢ page 252.
-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 checked
and adjusted when the tires are cold. The
s li ght ly ra ised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying .
- Reinsta ll the valve stem cap on the valve.
When should I check the tire pressure?
The correct tire pressure is espec ially impor
tant at high speeds. The pressure sho uld
therefore be checked at leas t once a mon th
and a lways befo re starting a journey. Do not
forget to check the tire pressure for the spare
wheel.
When should I adju st the tir e pres sures?
Ad just the tire p ressu re to the load you are
carry ing . After changing a wheel
o r replacing
wheels you have to adjust the tire pressures
on all wheels . In addition, you must then
store the new tire pressures in the tire pres
sure monitor ing system* ¢

A WARNING
Incorrect tire pressures and/or underinfla
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
[I] appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla
tion can cause increased tire wear and can affect the handling of the vehicle and
stopping ability.
- I nco rrect tire pressures and/or underin
f lation can a lso lead to sudden t ire fail
ure, including a blowou t and sudden de
f lation, ca using loss of veh icle contro l.
- The drive r is responsib le for the co rrec t
tire pressures for all tires on the veh icle.
The applicable pressure values are locat
ed on a sticke r on the driver's side B-pil
lar.
- On ly when all tires on the vehicle are fil
led to the correct pressure, the tire pres
sure mon itor ing system* can work cor
rectly.
- The use of incorrect tire pressure va lues
can lead to acc idents or other damage.
Therefore it is essential that the driver
observe the spec ified t ire pressure values
for the tires and the correct pressures for
the function of the t i re p ress ure monito r
ing system*.
- Always inf late tires to the recommended
a nd correct t ire p ress ure before dr iv ing
off.
- Driving with underinflated tires bend
mo re, letting t hem get too hot resulting
in tre ad separation, s udden tire failure
and loss of cont rol.
- Excessive speed and/overloading can
cause heat b uild- up, sudden tire failure
and loss of cont rol.
- If the tire pressure is too low or too high,
the t ires will wear prema turely and the
vehicle wi ll not handle well. .,.. •

256 Tire s and wheel s
-If the tire is not flat and you do not have
to change a wheel immed iately, drive at
reduced speed to the nearest service sta
t ion to check the tire pressure and add
air as required .
(D Note
Driving without va lve stem caps can cause
damage to the t ire valves . To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely mounted on the
valve .
@) For the sake of the environment
Underinf lated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire ca n car ry.
A vehicle that is overloaded w ill not ha ndle
well a nd is more difficult to stop. Over load ing
can not on ly lead to loss of vehicle contro l,
but can a lso damage important parts of the
ve hicle and can lead to sudden tire failure , in
cluding a blowout and sudden deflation that
can cause the veh icle to crash .
Your safety and that of yo ur passenge rs a lso
depends on making sure that load limits are not exceeded. Vehicle load includes everybody
a nd everyth ing in and on the vehicle . T hese
load limits are tech nica lly refe rred to as the
ve hicle 's
Gross V ehicle Weight Rating
("GVWR").
The "GVWR" includes the we ight of the basic
vehicle, all factory insta lled accesso ries, a full
tank of fuel, oi l, coo la nt and othe r fluids pl us
maximum load. The maxim um load includes
the number of passengers that t he vehi cle is
intended to carry ("seating capacity") w ith an
assumed weight o f 150 lbs (6 8 kg) for each
passenger at a designated seating pos ition
and the tota l weight of any l uggage in th e
ve
hicle. If you tow a trailer, the weight of the
trailer hitch and the tongue weig ht of the loaded tra
ile r must be included as part of the
vehicle load .
T he
Gro ss Axle Weight Rating (" GAWR") is
the max imum load th at can be applied at e ach
of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weight Ra ting are listed on the
sa fety comp liance s ticke r label lo cated on the
driver's side B-pillar. Your Audi has 5 seat ing
positions, 2 in the front and 3 in the rear fo r
total seat ing capac ity of 5. Each seating posi
t ion has a seat be lt
c:> page 149, Safety bel ts.
The fact that there is an upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is being car
ried in the vehicle ( includ ing the weight of a
tra iler hitch and the tongue weight of the
loaded tra iler) is lim ited . The more passen
gers in the vehicle or passenge rs w ho are
heavier than th e standard we ights assumed

A WARNING
Overloading a vehicle can cause loss of ve
hi cle cont ro l, a c rash or other accident, se
rious personal injury, and even death.
- Ca rrying more we ight than your veh icle
was des igned to carry wi ll prevent the
veh icle from handling pr operly and in

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 ve
hicle's placard (tire inflation
pressure label)
¢ page 252,
fig. 203.
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 pas sengers from
"XXX" kilo
grams or
"XXX" pounds
Tires and wheels 257
shown on the sticker
¢page 252, fig. 203.
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 50
(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 luggage load capacity of
your vehicle.

258 Tires and wheels
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balancing, correct tire pressure and driv
ing style.

F ig. 206 Rotat ing t ires for more ev en wea r
Tread Wear Indicator (TWI)
The o rigi na l tires on your veh icle have
1/16 inch (1.6 mm) high "wear indicators"
c::> fig . 205 running across the tread. Depend
i ng on the make, there will be six to eight of
them evenly p laced around the t ire. Marks on
the tire sidewa ll (for example "TWI" or other
symbols) indicate the positions of the tread
wear ind icators . Worn t ires must be replaced .
Different fig ures may apply in o ther countries
c::> & .
Tire p ressure
Incorrect tire pressure causes premature wear
a nd can cause sudden t ire blow-out. For th is
reason, tire pressure must be checked at least
once a month
c::> page 254.
Driving style
Driving fast aro und curves, heavy acce leration
and hard braking increase tire wear.
Rotating tires for more even wear
F or all four tires on your ve hicl e to h ave the
same service life, we recommend that the
front and rear t ires are rotated according to
the tire manufacturer's suggested tire rota
tion intervals. Please remember the follow
ing :
- Tire rotation intervals may differ from the
vehicle service inte rva ls o utlined in your
Ma intenance and Warranty Book let .
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufact urer's suggested
tire rotation intervals .
- Vehi cles w ith front-wheel dr ive experience
more tread wear on the front wheels com
pa red to all-wheel drive (quattro ®).
- Please rotate tires as shown
c::> fig. 206.
-Extra care must be taken when rotating di-
rection-specific tires
c::> page 278 .
Wheel balancing
The wheels on new ve hicles are balanced .
However, various situations during everyday
driving can cause them to become unbal
anced, re sulting in vibrat ions you can usually
feel through the steer ing wheel.
Un balanced whee ls must be rebalanced to
avoid excessive wear on steering, suspension
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 alig nment can cause exces
sive tire wear, impairing the safety of the veh i
cle . If tires show excessive wear, have the
whee l alignment checked by an authori zed
Audi dealer or qualif ied workshop .
All-wheel driv e
Vehicles with q uattro ® mus t always have tires
of the same size, construction and tread type .
