General notes I)
Each tire, including the spare (if provided}, should be checked
month ly when cold and inflated to the inflation pressure recom­
mended by the vehicle manufacturer on the vehicle placard or tire
inflation pressure label. (If your vehicle has tires of a different size
than the size indicated on the vehicle placard or tire inflation pres ­
sure label, you should determine the proper tire inflation pressure
for those tires.}
As an added safety feature, your vehicle has been equipped with a
tire pressure monitoring system (TPMSl that illuminates a low tire pressure tellta le when one or more of your tires is significantly
under-inflated . Accordingly, when the low tire pressure te lltale i llu ­
minates, you should stop and check your tires as soon as possible,
and inflate them to the proper pressure. Driving on a significantly
under -inflated tire causes the tire to overheat and can lead to tire
Controls and equip ­
ment

failure . Under -inflation also reduces fuel efficiency and tire tread
life, and may affect the vehicle's handling and s topping ability.
Please note that the TPMS is not a substitute for proper tire mainte ­
nance, and it is the driver 's responsibility to maintain correct tire
pressure, even if under-inflation has not reached the leve l to trigger
illumination of the TPMS low tire pressure te lltale.
Your vehic le has a lso been equipped with a TPMS malfunction indi­
cator to indicate when the system is not operating proper ly. The
TPMS ma lfunction indicator is combined w ith the low ti re p ressure
tel ltale . When the system detects a malfunction , the telltale wil l
flash for approximately one minute and then remain continuously
il luminated . This sequence will cont inue upon subsequent vehicle
start -ups as long as the malfunction exists.
When the ma lfunction indicator is illuminated, the system may not
be able to detect or signal low tire pressure as intended . TPMS
mal functions may occur for a variety of reasons, including the
insta llation of replacement or alternate tires or wheels on the
vehic le that prevent the TPMS from funct ioning properly. A lways
check the TPMS malfunction tellta le after replacing one or more
tires or whee ls on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to continue to function
properly. •

Introduction
The tire pressure monitoring system moni tors air pressure
in all four roa d wheels and the spare tire* while the
vehicle is moving.
As soon as the tire pressure monitoring system senses a significant loss of air pressure in one o r severa l tires, text messages and yellow
symbo ls appear in the instrument cluster display to alert the driver.
The L warni ng light in the instrument cluster comes on when the
tire is significantly underinflated
=> page 20. _,,
I • •

Driver inf ormati on displ ay
The warning light n also illuminates in the case of a system
mal fu n ction.
The system continuously receives radio signals from sensors located inside each tire .
Be aware that tire pressure is also dependent on the temperature of
the tire. For every 18 °F (10 °C) increase in tire temperature, tire pres­
sure increases by about
1 .5 psi (0.1 bar). The tire warms up while the
vehic le is moving and tire pressure rises. So you should adjust tire
pressure only when the tires are
cold, when the temperature of the
tires is roughly the same as the ambient air temperature .
In order to keep the tire pressure monitoring system properly cali ­
brated, tire pressure on al l four tires and on the spare tire * should
be checked at regular intervals, adjusted if necessary and sav ed in
the proper setting (recommended pressure) =>
page 44.
The tire pressure is shown on the tire pressure label. On USA vehi­
cles, the tire pressure label is located on the driver's side B -pi llar. On
Canada vehicles, the tire pressure labe l is located either on the
driver's side B -pil lar or inside the fuel filler flap . The tire pressu re
label lists the recommended cold t ire inflat ion pressures for the
vehic le at its maximum capacity weight and the tires that were on
your vehicle at the time it was manufactured . For recommended tire
pressures for normal load conditions, please see chapter
=>

[ i ] Tips
• Each tire, includin g the sp are*, should be checked monthly when
cold and set to the recommended inflation pressure as specified on
the tire pressure label=>
page 330.
• T he tire pressure monitoring system he lps the d river to keep an
eye on tire pressures . But the dr iver st ill has the responsibility for
maintaining the correct tire pressure .
• Tire pressure must only be adjusted when the temperature of the
tires is about the same as ambient air temperature.
• When tires are replaced, the sensors and valves shou ld not be
detached or exchanged . Only the valve core needs to be replaced
and, if necessary, the va lve and the wheel electronics replaced .
• If you should put different whee ls and tires on your vehicle (e.g .
winter wheels and tires), you must be certain that the wheels and
tires are compatible with the tire pressure monitoring system. Otherwise the system will register a ma lfunction and a fault
message will be displayed. For more information , contact your
authorized Audi dea ler.
• Adjust the tire pressure and store the pressure in the tire pres ­
sure mon itor ing system to the load you are carrying=>

Maintaining proper tire pressure is one of the most important
things you can do to help avoid sudden tire failure. Underinflated
tires are a major cause of sudden tire failure. Keeping tires at the
right pressure is also important for safe and responsive vehicle
handling, traction, braking and load carrying. Tire pressures are
particularly important when the vehicle is being driven at higher
speeds, and then especially when heavily loaded even within the
permissible load-carrying capacities approved for your vehicle.
The recommended tire pressures for your Audi depend on the kind
of tires on your vehicle and the number of passengers and/or
amount of luggage you will be transporting.
•
Tire pressure generally refers to the amount of air in a tire 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 kilopascals
(kPa), the international measuring unit and in pounds per square
inch (PSI). Tire pressure is based in part on the vehicle's design and
load limit -the greatest amount of weight that the vehicle can carry
safely and the tire size. The proper tire pressure is frequently
referred to as the "recommended cold tire inflation pressure ." Air in
the tires expands when the tire heats up because of internal friction
when 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
"cold" tire that counts. Therefore, you should never let air out of a
warm tire to match "cold tire inflation pressure " recommendations .
The tires would then be underinflated and could fail suddenly. On
USA vehicles, the tire pressure label is located on the driver's
side 8-pillar . On Canada vehicles, the tire pressure label is located
either on the driver's side 8 -pillar or inside the fuel filler flap . The tire

& WARNING
Overload ing a vehicle can cause loss of vehicle control , a crash or
other accident, serious personal injury , and even death .
• Carrying more weight than your vehicle was des igned to carry
will prevent the vehicle from handling properly and increase the
risk of a loss of vehicle control . .,_

Tires and wheels -
----------------
•
& WARNING (continued)
• 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 overloaded can fail suddenly
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 Rating.
& WARNING
• Incorrect tire pressures and/or underinflation can lead to a
serious or fatal accident.
• Incorrect tire pressures and/or underinflation cause increased
tire wear and can affect the handling of the vehicle.
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control. •
Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
either on driver's side 8-pillar or inside the fuel filler flap.
The recommended tire pressures are on the tire pressure label and
in the table~
page 330, "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 miles (kilometers) at low
speeds during the previous three hours. Air in the tires expands
when the tire heats up as a result of internal 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 "cold" tire that counts. Therefore, you
should never let air out of a warm tire to match "Cold tire inflation
pressure" recommendations~
page 330. The tires would then be
underinflated and could fail suddenly.
The tire pressure label on your Audi lists the recommended cold tire
inflation pressures at maximum capacity for the new, original equip ­
ment tires that were on your vehicle at the time it was manufac­
tured. For the location of the label
~ page 330, fig. 274.
Most tires lose air naturally over time. They can also lose some air if
you drive over a pothole or hit a curb while parking. It is usually not possible to see whether the radial tires used today are underinflated
just by looking at them.
Therefore, be sure to check tire pressures at least once a month and
always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you would not consider to be
"long ." See~
page 335, "Tires and vehicle load limits" for more
important information.
Always use an accurate tire pressure gauge when checking and
adjusting inflation pressures . Check all of the tires and be sure not
to forget the spare tire . If the pressure in any tire is too high 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 difference between the
pressure in the cold tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you
plan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember that the vehicle manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle. .,,_

road hold ing and safe handling when in good cond ition and prop­
erly inflated =>& .
We recommend that a ll work on tires and wheels be performed by
an authorized Audi dealer. They are familiar with recommended
procedures and have the necessary special tools and spare parts as
well as the proper facilities for d isposing of the old tires.
Authorized Audi dea lers have the necessary info rmation about tech ­
nical requirements for insta lling or changing tires and rims.
R epl ac ing tires and wheels
Tires shou ld be replaced at least in pairs and not individually (for
examp le both front tires or both rear tires together).
Be sure to read and heed the information to the tire pressure moni ­
toring system*=>
page 340.
Always buy replacement radial tires that have the same specifica ­
tions as the tires approved for your vehicle by Audi. Rep lacement
tires must always have the same load rating specification as the
origina l equipment or approved optional t ires listed in the table
=>
page 330.
Audi -appr oved spec ification tires are spec ially matched to your
vehicle and its load limits, and can contribute to the important road- holding, driving characteristics, and safety of the vehicle
. The table
(=>
page 330) l ists specifications of the tires approved for the Audi
models covered by your Owner's Literature.
The tire pressure labe l located either on driver's side 8 -pi llar or
inside the fuel fi ller flap(=>
page 330, fig. 275) lists the specifica ­

• T he battery inside of the tire pressure sensor has a limited
service life.
• Always drive with the va lve stem caps securely mounted. We
recommend using fac tory insta lled valve stem caps . Ask your autho­
rized Audi dealer to replace lost valve stem caps .
T he installation of replacement tires with steel cord body plies in
the tire sidewall may cause malfunction of the tire pressure moni ­
toring system *, and is not recommended (cord material info rmation
i n molded on the t ire sidewa ll).
A lways check your tire pressure monitoring system * indicator after
replac ing one or more tires on you r veh ic le . If t he tir e pressure
monitoring system * indicator f lashes, or is on, your system is not
wo rking pr ope rly. Your re place ment tire might be i nco m patible wit h

& WARNING
• Using incorrect or unmatched tires and / or wheels or improper
tire and wheel combinations can lead to los s of control , collision
and serious personal injury .
• Alway s use tires , rims and wheel bolts that meet the specifica ­
tions of original fa ctory -installed tires or other combination s that
have been specifically approved by the vehi cle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
espe cially at high speeds . Tire s that a re more than 6 years old can
only be used in an emergency and then with special care and at
lo wer speeds .
• Never mount used tire s on your vehicle if you are not sure of
their "previous history ." Old used tires may have been dam aged
even though the damage cannot be seen that can lead to sudden
ti re failure and lo ss of vehicle control.
• All four wheels must be fitted with radial tires of the same type ,
size (rolling cir cumference ) and the same tread pattern . Driving
& W ARNING (continued )
with different tires redu ces vehicle handling and can lead to a loss
of control.
• If the spare tire is not the same as the tires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and dri ve with extra care . Refit the
normal road wheel as soon a s safely pos sible.
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause heat build -up , su dden tire failure ,
includ ing a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated and
not over or underinflated .
• For te chni cal reasons it is not always po ssible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels , make sure
that the air flow to the brakes is not blo cked . Redu ced airflow to
the brake s can them to overheat , increa sing stopping distances
and causing a collision.
