Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of a vehicle.
Fig. 168 T ire press ure label : located on driver's side B·
pillar
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 ion pressu re i n a "cold" tire that counts.
T herefore, 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 re a ma jo r cause of s udden tire failure. Keep·
i n g tires at the right pressu re is also impor­
tant for safe and responsive vehicle handling,

XL= reinfo rced or extra load tire. It may also appear as xl, EXTRA LOAD, or RF on the tire side-
wall.
The correct tire pressure for the spare wheel is
lo cated on a label on the driver's side B-pillar.
Because technical changes may be made to
vehicle equipment during t he model year, al­
ways compare the tire size designation on the
tire pressure label 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
l ongs to someone else or you bought the vehi- 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
Rat ing ("GVWR"). The Gross Axle Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two axles .

Gross Axle Weight Rating are listed on the
safety compliance sticker labe l located on the
driver's side B-p illar. The tire pressure label on
your Audi lists the maximum combined weight of all of the occupants and luggage or
other cargo that the vehicle can carry. For t he
locat io n of the tire pressure label

A WARNING
Overl oading a vehicle can cause loss of ve­
hicle control, a cras h or other accident, se­
r ious personal inju ry, and even death.
- Carry ing more weight than yo ur vehicle
was designed to ca rry will p reven t the
vehicle from hand ling properly and in­
crease the risk of a loss of veh icle con­
t ro l.
- T he brakes on a veh icle that has been
overloaded may not be able 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 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 ca n also lead to sudden tire fa il­
ure, including a blowo ut and sudden de­
fla tion, causing loss of vehicle con trol.
-
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
t ir e p ressu re label a nd in the table
r::::;, page 226, Cold tire inflation pressure. This
means tha t the pressu re must be che cked and
adjus ted whe n the t ire has not been dr iven fo r
more than a couple of miles (kilometers) at
l ow speeds d uring the previous t hree ho urs.
Air in the tires expands when the tire heats up as a result of interna l frict ion as it flexes in
use. The tire pressure is higher when the tire
has warmed up than when 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" recommendat io ns
r:::;, page 226 . The
t ires wou ld then be unde rinflated 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, or ig inal
equipment tires that were on your vehicle at
t h e time it was ma nufactu red. Fo r the loca­
t ion of the labe l
r:::;, page 226, fig. 168.
Most t ires lose air naturally over t ime . 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 poss ible to see whethe r the rad ial tires
u sed today are underinfla ted just by loo king
at them .
T he refore, be sure to check t ire p ressu res at
l east on ce a mo nth and a lways befo re going
o n a long trip. M ake s ure to ta ke the n umbe r
of peop le and the amount of luggage into ac ­
count when adjusting tire pressure for a trip -
even one that yo u wo uld not consider to be
"long." Seer:::;,
page 230, Tires and vehicle
load limits
for more important information.
Always use an accurate tire press ure ga uge
when checking and ad justing inflat ion pres­
s u res. Check all of the tires and be sure not to ..,.

forget the spare tire. If the p ress ure in any tire
is too high when the tire is "cold", let air out
of the tire slowly with the edge of the t ire
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 veh icle load (passengers and luggage) for
the tires on your veh icle as listed on the on
your ve hicle and in this manua l and the kind
of dr iving you p lan to do .
Never exce ed the ma ximum inflation pres ­
s ur e listed on t he tire s idewall for any re a­
s on.
Remember that the vehicle manufacturer , not
the t ire manufacturer , determ ines the co rrect
tire pressure for the tires on your veh icle .
It is important to check the tire pressure when
the t ires a re cold .
- Read the req uired tire press ure from the tire
pressure label. The tire pressure labe l is lo­
cated on the driver's side 8 -p ill ar . The tire
pressure label lists the recommended cold
t ir e inflat io n pressu res for the veh icle at its
maximum capacity we ight a nd the tir es that
we re on yo ur vehicle at the t ime it was man­
uf act ured. Fo r recommended tire press ures

- Turn the valve stem cap counter -clockwise
to remove it from the tire valve.
- Place the air pressure ga uge on the valve.
- The tire pressures should on ly be che cked
and adjus ted when the tires a re cold . The
s li ght ly raised pressures of wa rm tires mus t
not be reduced .
- Adjus t the tire pressure to the load you are
carrying .
- Re inst all the va lve s tem cap o n the valve .

When should I check the tire pressure?
T he co rrect tire pressu re is especially impor­
tant at h igh speeds. The pressure should
therefore be checked at least once a month
and always before sta rting a jo urney . Do not
forget to check the tire pressure for the spare
whee l.
When should I adjust the tire pres sures?
Adjust the t ire pressure to the load you a re
carrying . After changing a whee l
or replacing
whee ls yo u have to adjust the tire pressu res
on all whee ls. In addition, yo u m ust then initi­
alize the new tire pressures i n the t ire pres­
sure monitoring system*

A WARNING
Incorrect ti re p ressu res and/or u nderinfla­
tion can lead sudden ti re fa ilu re, loss of
control, collision, se rio us pe rsonal inju ry
or even death.
- When the
RI] warning symbol appears i n
the ins trumen t cluster, stop and inspec t
the t ires.
- In co rrec t tire p ressure a nd/or underi nfla­
tion can ca use increased tire we ar and
can affect the hand ling of the vehicle and
stopping ability.
- In correc 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 drive r is responsib le for the co rrect
tire pressures for all tires on the vehicle.
The applicable pressure values are locat ­
ed on a sticke r on the dr iver's s ide 8-pil­
lar.
- On ly 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 va lues
can lead to acc idents or other damage.
Therefore it is essential that the drive r
observe the spec ified t ire p ress ure val ues
for the tires and t he correct pressures fo r .,. •

Tires and vehicle load limits
There are limits to the amo unt of load or
weight that any vehicle and any t ire can carry .
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overloading
can not only lead to loss of vehicle contro l,
but c an also damage import ant parts of the
vehicle and can lead to sudde n tire failure, in­
cluding a blowout and sudden deflation that
can cause t he veh icle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded . Vehicle load includes everybody
and everyth ing in and on the vehicle. These load lim
its are technically referred to as the
vehicle's
Gro ss Vehicle Weight R ating
("GVWR").
T he "GVWR" includes t he weight of the basic
vehicle , a ll f actory installed accessories, a f ull
tank of fuel, oi l, coo lant and other f luids plus
maximum load. The max imum load incl udes
the number of passengers that the vehicle is
intended to carry ("seat ing capac ity ") wi th an
assumed we ight of 150 lbs . (68 kg) for each
passenger at a designated seating posit ion
and the total weight of a ny luggage in the ve­
hicle. If you tow a trai le r, the we ight of the
t ra ile r hi tc h and the tongue we ight of the
l oaded tra iler mus t be include d as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating ("GAWR ") is
the max imum load that can be applied a t each
of the veh icle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weig ht Ra ting are listed on the
sa fety comp lian ce s ticke r label loca ted on the
driver's side B-pillar. Yo ur Audi has 4 seat ing
pos itions , 2 in the front and 2 in the rea r fo r
total seati ng capacity of 4. Each seating posi­
t ion has a seat belt c:>
page 129, Safety belts.
T he fact that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
t h at 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 who are
heavier tha n the sta ndard we igh ts assumed
mean that less we ight can be carried as lug­
gage.
The tire pressure label o n your Aud i also lists
the max imum combi ned weig ht of all of the
occupants and luggage or other cargo that
t h e vehi cle can carry . Fo r th e lo ca tion of the

8_ WARNING
<=
Over loading a vehicle can cause loss o f ve -
hicl e co ntro l, a c rash 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 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)
c::> page 226,
fig. 168.
Tires and wheels 231
2. Determine the combined weight of the driver and pas­sengers 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
c::> page 226, fig. 168.
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 ..,.

Incorrect wheel alignment
Incorrect wheel alignment can cause exces­
sive tire wear, impairing the safety of the vehi­
cle. If tires show excessive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop .
All wheel drive
Vehicles with quattro must always have tires
of the same size, construction and tread type.
For details see
~page 185 .
.8_ WARNING
Sudden tire failure can lead to loss of con­
trol, a crash and serious personal injury!
- Never drive a vehicle 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 "hydroplaning" and toss 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 sudden tire failure
and loss of vehicle control.
