When should I adjust the
tire pressures?
Adjust the tire pressure to the load you are carrying. After
changing a wheel
or 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 pressure monitoring sys­
tem

A WARNING
Incorrect tire pressures and/
or underinflation can lead sudden tire failure, loss of
control, collision, serious per­
sonal injury or even death .
-When the warning symbol
II] appears in the instru­
ment cluster, stop and in­
spect the tires.
-Incorrect tire pressure and/ or underinflation can cause
increased tire wear and can
affect the handling of the
vehicle and stopping ability.
- Incorrect tire pressures
and/or underinflation can
also lead to sudden tire fail­
ure, including a blowout
and sudden deflation, caus­ ing loss of vehicle control.

-The driver is responsible for the correct tire pressures for all tires on the vehicle. The
applicable pressure values
are located on a sticker on
the driver's side 8-pillar.
-Only when all tires on the vehicle are filled to the cor­rect pressure, the tire pres­
sure monitoring system can
work correctly.
-The use of incorrect tire pressure values can lead to
accidents or other damage.
Therefore it is essential that
the driver observe the speci­
fied tire pressure values for
the tires and the correct
pressures for the function of
the tire pressure monitoring
system.
-Always inflate tires to the recommended and correct
tire pressure before driving
off.
-Driving with underinflated tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con­
trol.
-Excessive speed and/over­ loading can cause heat •

- The brakes on a vehicle that
has been overloaded may
not be able to stop the vehi­
cle within a safe distance.
-Tires on a vehicle that has been overloaded can fail
suddenly, including a blow­
out and sudden deflation,
causing loss of control and a
crash.
-Always make sure that the total load being transported
- including the weight of a
trailer hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rat­
ing.
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 WEIGH T OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi­
cle's placard (tire inflation
pressure label)
~ page 2 78,
fig . 250 .
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 278, fig. 250.
4. The resulting figure equals
the available amount of car­go 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 -750
(5
X 150) = 650 lbs.)
5. Determine the combined weight of luggage and cargo .,..

tires because they meet the highest standards regarding
safety and driving characteris­
tics when used correctly. Your
authorized Audi dealer will
gladly provide you with more
information.
Tire ply composition and materials used
The number of plies indicates
the number of layers of rubber­
coated fabric in the tire. In gen­
eral, the greater the number of plies, the more weight a tire
can support. Tire manufactur­
ers also must indicate the ma­
terials in the tire, which include steel, nylon, polyester, and oth­
ers .
Maximum Load Rating
This number indicates the max­
imum load in kilograms and
pounds that can be carried by
the tire.

A WARNING
- Using incorrect or unmatch­
ed tires and/ or wheels or
improper tire and wheel
combinations can lead to
loss of control, collision and
serious personal injury.
-Always use tires, rims and wheel bolts that meet the specifications of original
factory-installed tires or
other combinations that have been specifically ap­
proved by the vehicle manu­
facturer.
-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

securely and that the brake system functions
correctly .
I n certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
¢ page 328.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­
erly 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 tighten ing
torque for the wheel bolts to reduce the
risk of a wheel loss.
If the tightening tor­
que of the wheel bolts is too low, they
can loos en and come out when the vehi­
cle is moving .
If the tightening torque is
too high, the whee l bolts and threads
can be damaged and the wheel can be­
come loose.
{[) Note
The specified torq ue for the wheel bolts is
120 ft lb (160 Nm) with a tolerance of
± 7,4 ft lb(± 10 Nm). Torque whee l bolts
diagonally. After changing a whee l, the
torque must be checked as soon as possi­
ble with a torque wrench -preferably by an
author ized Audi dealer or qualified work­
shop.
Low aspect ratio tires
Your Audi is factory-equipped w ith low aspect
ratio tires. These tires have been thoroughly
tested and been se lected specifically for your
model for their superb performance, road feel
and handling under a variety of driving condi­
t ions . Ask your authorized Audi dealer for
more details.
The low aspect ratio of these tires is indicated
by a numera l of
55 or less in the tire's size
designation. The numera l represents the ratio
of the tire's sidewall height in relation to its
tread width expressed in percentage. Conven­
t iona l tires have a he ight/w idth ratio of 60 or
more .
The performance of low-aspect-ratio tires is
particularly 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 always before a long trip
¢ page 282, Checking tire pressure .
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact with potholes, curbs, gullies
or ridges on the road, particularly if the tire is
underinflated .
In order to minimize the occurrence of impact
damage to the tires of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add air if neces­
sary .
- Drive carefully on roads with potholes, deep
gullies or ridges. The impact from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires .
- After any impact, immed iately inspect your
tires or have them inspected by the nearest

authorized Audi dealer. Replace a damaged
tire as soon as possible.
- Inspect your tires every 2 ,000 miles (3,000
km) for damage and wear. Damage is not a l­
ways easy to see . Damage can lead to loss of
air and underinflation, which could eventu­
ally cause tire failure. If you be lieve that a
t ire may have been damaged, replace the
t ire as soon as possible .
- These tires may wear more quick ly than oth­
ers .
- Please also remember that, while these tires
deliver respons ive handling, they may ride
less comfortably and make more noise than
other cho ices .
Reduced perform ance in winte r/cold
s eason conditions
All tires are des igned for certai n purposes.
The low aspect ratio, ultra high pe rformance
tires orig inally installed on your veh icle are in­
tended fo r max imum dry and wet road per­
formance and handling . They are not s uitable
for cold, snowy or icy weather conditions. If
you drive under those circumstances, you should equip your vehicle with all-season or
winter tires, which offer better traction under those cond itions . We suggest you use the rec­
ommended snow or all-season tires specified
for your vehicle, or their equ ivalent .
Refer to
c> page 298 for more detailed infor­
mat ion regarding winter t ires.
Tire pressure
monitoring system
(D General notes
Each t ire, includ ing the spare (if provided),
should be checked monthly when cold and in­
flated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
p lacard or tire inflation pressure label. (If your
ve hicl e has t ires of a different size than the
si ze ind icated on the vehicle p lacard or tire in­
flation pressure label, yo u should determine
the proper tire inflation pressure for those
tires).
Tire s an d wheel s 301
As an added safety featu re, your veh icle has
been equipped with a tire pressure monitoring
system (TPMS) that illum inates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. According­
ly, when the low tire pressure telltale illumi ­
nates, you should stop and check your tires as
soon as possib le, and inflate them to the
proper pressu re. Driving on a sign ifi cantly un­
der- infla ted ti re causes the tire to overhea t
and can lead to tire fa ilure . Unde r-inflation al­
so reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and
stopp ing ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the driv ­
er's responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to tr igger illuminat ion of the
TPMS low tire pressure tellta le.
Your vehicle has also been equipped with a
T PMS malfunction ind icator to ind icate when
the system is not operating properly . The
TPMS malfunction indicator is combined with
the low tire pressure telltale . Whe n the sys ­
tem detects a malfunction , the telltale will
flash for approximate ly one m inute and then
rema in continuously illum inated . Thi s se ­
quence will continue upon s ubseque nt vehicle
start-ups as long as the malfunct ion exists.
When the malfunction indicato r is illum inat­
ed, the sys tem may not be ab le to detect or
s ignal low tire pressure as intended. TPMS
malfunctions may occur for a var iety of rea­
sons, including the insta llation of rep lace­
ment or a lternate tires or wheels on the vehi­
cle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction
telltale after rep lacing one or more tires or
whee ls on your vehicle to ensure that the re ­
placeme nt or alternate ti res and wheels allow
the TPMS to cont inue to funct ion p rope rly . •

Tire pressure indicator appears
The tire pressure indicator in the instrument
cluster informs you if the tire pressure is too
low or if there is a system malfunction.
F ig . 255 D isp lay: underinflation warn ing
Using the ABS sensors, the tire pressure moni­
toring system compares the tire tread circum­
ference and vibration characteristics of the in­
d iv idual tires. If the pressure decreases in one
or more tires, this is indicated in the instru­ ment cluster with a
RE warning symbol and a
message ¢
fig. 255 . The dr iver message in the
d isplay goes out after 5 seconds . The dr iver
message can be displayed again by pressing
the
! CHECK I button. If only one tire is affect­
ed, the display will indica te its pos ition.
The tire pressure monitoring must be reset via MMI each time the pressures are adjusted (e.
g. when switch ing between partial and full
l oad pressure) or after changing or replac ing a
tire on your vehicle¢
page 303. The TPMS in­
dicator only monitors the tire pressure that
you have previously stored. You can find the
recommended tire pressures for your vehicle
on the label on dr iver's side 8-pillar
¢page 278.
Tire tread circumference and vibration charac­
teristics can change and cause a tire pressure

A WARNING ......_
- If the tire pressure ind icator appears in
the instrument cluster display, one or
more of your t ires is sign ificant ly under­
inflated . Reduce your speed immediately
and avoid any hard steer ing or b raking
maneuvers. Stop as soon as possib le and
check the tires and their pressu res. In ­
flate the ti re p ressu re to the proper pres ­
sure as indicated on the vehicle's tire
pressure labe l
r=:>page 278. Driving on a
sign ificantly under-inflated tire causes
the t ire to overheat and can lead to tire
fa ilure. Under-inflation also is likely to
impair the vehicle's handl ing and stop­
p ing ability .
- The driver is responsible for maintaining
the correct tire pressures. You must
check the tire pressures regu larly.
- Under certain conditions (such as a spor­
ty driv ing style, winter conditions or un­
paved roads), the pressure monitor indi­
cator may be delayed .
-Ask you r aut horized Aud i dea ler if run­
flat t ires may be used on you r vehicle.
