2013 AUDI TT inflation pressure

A WARNING ,~
Heavy loads will influence the way your ve­
hicle handles. To help reduce the r isk of a
loss of control leading to ser ious personal
injury:
-Always keep in m ind when transporting
heavy objects, that a change in the cen­
ter of g ravity can also cause changes in
vehicle handling:
- Always distribute the load as even ly as
possible.
- Place heavy objects as far forward in
the luggage compartment as possible.
- Never exceed the Gross Ax le Weight Rat­
ing or the Gross Vehicle Weight Rating
specified on the safety compliance stick­
er on the left door jamb. Exceeding per­ missible we ight standards can cause the
vehicle to slide and handle differently .
- Please observe information on safe driv­
ing
i:> page 90.
A WARNING
To help prevent poisonous exhaust gas
from be ing drawn into the veh icle, always
keep the rear lid closed while dr iving.
- Never transport objects larger than those fitting completely into the luggage
area because the rear lid cannot be fully
cl osed.
- If you absolutely must drive with the rear
lid open, observe the follow ing notes to
reduce the risk of poisoning:
- Close all windows,
- Open all air outlets in the instrument
panel,
- Sw itch off the air recircu lation,
- Set the fresh ai r fan to the h ighes t
speed .
A WARNING
Always make sure that the doors, all win­
dows and the rear lid are securely closed
and locked to reduce the risk of injury
when the veh icle is not being used.
Dr iving S afel y 97
-After closing the rear lid, always make
sure that it is properly closed and locked.
- Never leave your vehicle unattended es­
pecially with the rear lid left open. A
child could crawl into the vehicle through
the luggage compartment and close the
rear lid becoming trapped and unable to
get o ut. Being trapped in a vehicle can
lead to serious personal injury.
- Never let ch ildren play i n or around the
veh icle .
- Never let passengers ride in the luggage
compartment. Vehicle occupants must
always be prope rly restra ined in one of
the vehicle 's seating pos it ions .
(D Tips
- Air circulation helps to reduce window
fogging. Stale a ir escapes to the outside
through vents in the trim panel, on the
left side of the luggage compartment. Be sure to keep these s lots free and
open.
- The tire pressure m ust correspond to the
load. The tire pressure is shown on the
tire pressure label. The tire pressure la ­
bel is located on the driver's side B-pillar.
The tire pressure label lists the recom­
mended co ld tire inflation pressures for
the vehicle at its maximum capacity
we ight and the tires that were on your
vehicle at the t ime it was manufactured .
For recommended tire pressures for nor­
ma l load cond itions, please see chapter
i=>page 200.
Tie-downs
The luggage compartment is equipped with
four tie-downs to secure luggage and other
items.
Use the t ie-downs to secure your cargo prop­
erly

-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 .

Cold tire inflation pressure
Tire pressure affects the overall handling , p erformance and safe ty of a vehicle.
Fi g. 14 2 T ire p ress ure la b el: loca ted on driver's side B·
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

i n g tires at the right pressure is also impor­
tant for safe and responsive vehicle handling,

Remembe r, your safety and that of your pas­
sengers also depends on mak ing sure that
l oad limits are not exceeded . Vehicle load in­
cludes everybody and everything in and on the
ve hicle . These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR"). The Gross Axle Weight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the veh icle 's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rat ing a re listed on the
safety compliance st icker labe l located on the
d river's side B-pi llar. T he tire pressure label on
your Audi lists the maximum combined weight of a ll of the occupants and luggage or
othe r cargo that the vehicle can carry. For the
locat ion of the tire pressure label¢
fig. 142.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
r ious personal injury, and even death.
- Carry ing more weight than your vehicle
was designed to carry will prevent the
vehicle from handling p roperly and in­
c rease the risk of a loss of veh icle con­
tro l.
- T he brakes on a veh icle that has been
overloaded may not be ab le to stop the
vehicle within a sa fe distance.
- Ti res on a vehicle that has been overload­
ed can fail suddenly causing loss of con­
tro l and a crash .
A WARNING
-Incorre ct 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 wear and can affect the handling of the vehicle .
- Incorrect tire pressures and/o r underin­
flation can also lead to sudden tire fai l­
ure, incl uding a blowo ut and sudden de­
flation, 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
t ire pressure label and in the table
¢
page 200, 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 friction 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" tire that
counts. Therefore, you should never let air out
of a warm tire to match "Cold tire inflat ion
pressure" recommendat ions ¢
page 200 . The
t ires would then be unde rinflated and could
fail suddenly .
The tire pressure label on your Audi lists the
recommended co ld tire inflation pressures fo r
the new, orig inal equ ipment tires that were
on your veh icle at the time it was manufac­
tu red. Fo r the location of the labe l
¢page 200, fig . 142.
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 park ing. 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
least on ce a mo nth and a lways befo re going
on a long trip. Ma ke 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." See ¢
page 204, Tires and vehicle
load limits
for more important information.
Always use an accurate tire press ure ga uge
when checking and ad justing inflation pres­
s u res. Check all of the tires and be sure not to ..,.

forget the spare tire. If the press 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 correct
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 located on driver's s ide B-pil­
l ar .
- 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 sho uld on ly be checked
and adjusted when the tires are cold . The
s light ly 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 on the valve .
When should I check the tire pressure?
The correct tire pressure is espec ially impo r­
tant at high speeds . The pressure sho uld
therefore be checked at least once a month
and a lways befo re starting a journey.
When should I adjust the tire pressures?
Adj ust the tire pressu re to the load you are
carry ing . After changi ng a wheel
or replacing
Tire s an d wheel s 203
whee ls yo u have to adjust the ti re p ressu res
o n all whee ls. In addition, yo u m ust then initi­
a lize the new tire pressu res in the t ire pres­
s u re monitoring system
Q page 214.
A WARNING
Incorrect tire pressures and/or underinfla­
tion can lead sudden tire fa ilure, loss of
control, collision, serio us pe rsonal injury
or even death.
- When the warning symbol
[I] 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 ability.
- Inco rrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and su dden de­
flation, ca using loss of veh icle cont ro l.
- Th e drive r is responsi ble for the correc t
tire pressures for all tires on the veh icle.
The applicable pressure values a re locat ­
ed on a sticke r on the dr iver's side B-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 pressu re 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 th e ti r e p ressu re 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 unde rinflated tir es bend
mo re, letting t hem get too hot resulting
in tre ad separation, sudden tire f ailure
and loss of cont rol.
- Exces sive speed and/overloading can
cause he at bu ild- up, sudden tire failure
an d loss of cont rol. •

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)
¢ page 200,
fig . 142 .
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
shown on the sticker
¢ page 200 , fig. 142.
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.
Tires and wheels
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 re­duces the available cargo
and luggage load capacity of
your vehicle.
,... Check the tire sidewall
(¢ page 207, fig. 146) to de­
termine the designated load rating for a specific tire.
