The correct t ire pressure for the
spare wheel is located on a label
either on the driver's side B-pillar or inside the fue l filler flap.
Because technica l changes may be made to vehicle equipment
during the mode l year, always compare the tire size designat ion on
the tire pressure la bel on y our vehicle with the tires on your vehicle.
Make sure tha t the t ire size information on the veh icle labe l is the
same as the size of the tires on the vehicle. This is especially impor ­
t ant if the vehicle belongs to someone e lse or you boug ht the
vehic le with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and that of your passengers a lso depends
on making su re tha t load limits a re not exceeded . Vehicle load
inc ludes everybody and everything in and on the vehicle. These load
limits are technically referred to as the vehicle's Gross Vehicle
Weight Rating ("GVWR"). The Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each of the vehicle's two
ax les. The Gross Vehicle We ight Rat ing and the Gross Ax le Weight
Rating are listed on the safety comp liance sticker labe l located
e it he r on the d river's side B-pillar o r on the i nside of the fuel f iller
flap. The tire pressure label on your Audi lists the maximum
combined we igh t of all o f th e occupa nts and luggage o r other cargo t
hat the vehic le can carry. For the location o f the tire pressure labe l
=> page 246, fig. 173.
& WARNING
Overloading a vehi cle can cause los s of vehicle control , a crash or
other accident, serious per sonal injury, and even death .
• Carrying more weight th an your vehicle was de signed to carry
will prevent the vehicle from handling properly and increase the
risk of a loss of vehicle control.
• 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 c an fail suddenly
cau sing loss of control and a crash .
• Alway s make sur e that the total load being tran sported -
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
246, "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 246. The tires would then be
underinflated and could fail suddenly.
The tire pressure label on your Audi lists the recommended cold tire
inflation pressures for the new, original equipment tires that were
on your vehicle at the time it was manufactured. For the location of
the label =>
page 246, fig. 173.
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 250, "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.
It is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the tire pressure label. On
USA vehicles, the tire pressure label is located on driver's side B ­
pillar. On Canada vehicles, the tire pressure label is located either on
the driver's side B -pillar or inside the fuel filler flap.
• Turn the valve stem cap counter-clockwise to remove it from the
tire valve.
• Place the air pressure gauge on the valve. ..,.
Vehicle care I t •

-~_T_ ir_e_ s_ a_ n_d _ w_ h_ e_e _l_s _________________________________________________ _
• The tire pressures should only be checked and adjusted when
t he tires are cold . The s lig htly raised pressures of warm tires must
not be reduced .
• Adjust the ti re pressure to t he loa d you are carrying.
• Reinstal l the valve stem cap on the valve.
When should I c heck the tire pressure?
The correct ti re p re ssure is especially impo rtant at h ig h speeds . The
pressure should the re fore be checked a t le ast once a month and
a lways before starting a journey. Do not forget to check the tire pres ­
sure for the spare whee l
::::> page 269.
When should
I adjust the tire pressure s?
Adjust the tire pressure to the load you are carrying. A fter chang ing
a wheel
or r eplac ing whee ls you have to adjus t th e tire pre ssures on
a ll whee ls. In addit io n, you must the n initia lize the new t ire pres ­
sures in the tire pressure monitoring system* =>
page 263.
& WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure, los s of control, colli sion , serious personal injury or even
death .
• When the warning symbol appears in the instrument
c luster , stop and inspect the tire s.
• 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 underinfla tion can also lead to
sudden tire failure , including a blowout and sudden deflation ,
causing loss of vehicle control .
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pre ssure values are located on
a sticke r on the driver 's side B -pillar o r on the inside of the fuel
filler flap.
& WARNING (continued )
• Only when all tires on the vehicle are filled to the correct pre s­
sure , the tire pres sure monitoring sy stem * can work correctly.
• The use of incorrect tire pressure values can lead to accidents
or other damage . Therefore it is e ssential that the driver observe
the specified tire pressure v alue s for the tires and the correct pres­
sures for the function of the tire pre ssure monitoring system* .
• Always inflate tires to the recommended and correct tire pres ­
s ure before driving off.
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation , sudden tire fa ilure and loss
of control.
• Excessive speed and /overloading can cause heat build -up ,
sudden tire failure and loss of control.
• If the tire pressure is too low or too high, the tires will wear
prematurely and the vehicle will not handle well.
• If the tire is not flat and you do not have to change a wheel
immediately , drive at reduced speed to the nearest service station
to che ck the tire pressure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
va lves. To prevent this, always make sure that fac tory ins talled va lve
stem caps on all whee ls are securely mounted on the valve.
Underinflated tires wi ll also increase the fuel consumption. •

The tires and rims are essential parts of the vehicle 's design. The
tires and rims approved by Audi are specially matched to the char­
acteristics of the vehicle and can make a major contribution to good
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 disposing 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 individual ly (for
examp le both front tires or both rear tires together).
Be sure to read and heed the tire pressure monitoring sys tem*
information=>
page 256.
A lways 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 246.
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 246) lists 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 246, fig. 174) lists the specifica ­
tions of the original equipment tires installed on your vehicle at the
ti me it was manufactured.
Federa l law requires tire manufacturers to place standardized infor ­
mation on the sidewa ll of all tires =>
page 254, fig . 177. This informa ­
t ion identifies and describes the fundamental characteristics, the
qua lity grade of the ti re and also provides a tire identification
number for safety standard certificat ion and in case of a recal l.
Tire specificat ions
Knowledge of tire specifications makes it easier to choose the
co rrect t ires . Radial tires have the tire specifications marked on the
sidewall, for example :
P225 / 45 R 17 91H XL
This contains the fo llowing informa tion:
P Indicates the ti re is for passenger cars (where applicab le)
225 No minal tire width i n mm of the tire fro m sidewall edge to side -

& WARNING
• Using incorrect or unmatched 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 specifica ­
tions of original factory-installed tires or other combinations that
have been specifically approved by the vehicle manufacturer .
• Tires age even if they are not being used and can fail suddenly,
espe cially 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 history. " Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control.
& WARNING (continued )
• All four wheels must be fitted with radial tires of the same type,
size {rolling circumference ) and the same tread pattern. Driving
with different tires reduces 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 drive with extra care . Refit the
normal road wheel as soon as safely possible.
• Never drive faster than the maximum 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 , sudden tire failure ,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated and
not over or underinflated.
• For technical reasons it is not always possible 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 blocked . Reduced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision .
• Run flat tires may only be used on vehicles that were equipped
with them at the factory . The vehicle must have a chassis designed
for run flat tires and a factory-installed tire pressure monitoring
system* that indicates a loss of tire pressure . Incorrect use of run
flat tires can lead to vehicle damage or accidents . Check with an
authorized Audi dealer or tire specialist to see if your vehicle can
be equipped with run flat tires . If run flat tires are used , they must
be installed on all four wheels . Mi xing tire types is not permitted. _,.

0 Note
• For technical reasons, it is not generally possible to use the
wheel rims from other vehicles. This can hold true for wheels of the
same vehicle type.
• If the spare tire is different from the tires that you have mounted
on your vehicle (for example winter tires or wide profile t ires), then
use the spare tire for a short period of time only and drive with extra
care. Replace the f lat tire with the tire matching the others on your
vehic le as soon as possib le.
• If you put different whee ls and tires on your vehic le (e .g. winter
whee ls 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 malfunction and a fault message wi ll be
displayed. For more information, contact your authorized Aud i
dea ler.
(D Note
• When installing new tires, be careful not to damage the valves or
tire pressure monitoring system* sensors.
• Never drive without the valve stem cap. The valves could get
damaged.
• If the sensors must be replaced, then the valve must also be
replaced at the same time.
<£> For th e sake of the environm ent
Dispose of o ld tires in accordance with the loca l requirements. •
Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C Quality grades can be found where applicable on the tire side wal
l
between tread shoulder and maximum section width~
page 254,
fig. 177 .
For exa mple: Tread wear 200, Traction AA , Temperature A.
All passenger car tires must conform to Federal Safety Requ ire­
ments in addition to these grades.
T rea d w ear
The
tread wear grade is a comparative rating based on the wear rate
of the tire when tested under controlled condit ions on a specified
government test course .
Fo r example, a tire graded 150 wou ld wear one and one hal f (1 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actua l condi ­
tions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differ ­
ences in road characteristics and climate .
Tr act ion
The
traction grades, from highest to lowest, are AA, A, Band C.
T hose grades represent the tire 's ability to stop on wet pavement as
measured under contro lled co nditions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor traction performance
~ & .
Temp erature
T he
temperature grades are A (the highest), B , and C , represent ing
the tire's resistance to the generation of heat and its abi lity to dissi ­
pate heat when tested under control led conditions on a specified
indoor laboratory test wheel.
Susta ined high temperature can cause the mater ial of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure~& .
T he grade C corresponds to a leve l of performance which a ll
passenger car tires must meet under the Federal Motor Vehicle

________________________________________________ T_ i _r_e _s_ a_n_ d_ w_ h_ e_e _ l_s __ lfll
•
Safety Standard No. 109. Grades Band A represent higher levels of
performance on the laboratory test wheel than the minimum
required by law.
& WARNING
The traction grade assigned to this tire is based on straight-ahead
braking traction tests, and does not include acceleration,
cornering, hydroplaning or peak traction characteristics.
& WARNING
The temperature grade for this tire is established for a tire that is properly inflated and not overloaded. Excessive speed, underinfla­
tion , or excessive loading, either separately or in combination, can
cause heat buildup and possible tire failure. •
Winter tires
Winter tires can improve vehicle handling on snow and
ice. At temperatures below 45 °F (7 °C) we recommend
changing to winter tires.
In some heavy snow areas, local governments may require true
winter or "snow" tires, those with very deeply cut tread. These tires
should only be used in pairs and be installed on all four wheels.
Make sure you purchase snow tires that are the same size and
construction type as the other tires on your vehicle.
I f your vehicle is equipped with all-wheel drive*, this will improve
traction during winter driving, even with the standard tires.
However, we strongly recommend that you always equip all four
wheels on your vehicle with correctly fitted winter tires or all-season
tires, when winter road conditions are expected . This also improves
the vehicle's braking performance and reduces stopping distances.
Summer tires provide less grip on ice and snow . Winter tires (snow tires) must always be fitted on all four wheels
.
Compatible tire pressure monitoring sensors* must be installed on
all four winter tires for the tire pressure monitoring system* to func­
tion properly ~
page 256.
Ask your authorized Audi dealer or qualified workshop for permitted
winter tire sizes . Use only radial winter tires.
Winter tires lose their effectiveness when the tread is worn down to
a depth of 0.157 inch (4 mm) .
Only drive with winter tires under winter conditions. Summer tires
handle better when there is no snow or ice on the roads and the
temperature is above 45 °F (7 °C).
If you have a flat tire, see notes on spare wheel
~ page 254.
Please always remember that winter tires may have a lower speed
rating than the tires originally installed on your vehicle at the time
it was manufactured . Please see~
page 256, "Speed rating (letter
code)" for a listing of the speed rating letter codes and the
maximum speed at which the tires can be driven.
The speed rating letter code(~
page 256) is on the side wall of the
tire
~ page 254.
& WARNING
Winter tires have maximum speed limits that may be lower than
your vehicle's maximum speed. Always know the maximum speed
before driving off. Never drive faster than the speed permitted for
your specific winter tires. This will cause damage to the tires leading to an accident and serious personal injury to you and your
passengers.
& WARNING
Driving faster than the maximum speed for which the winter tires
on your vehicle were designed can cause tire failure including a
blowout and sudden deflation, loss of control, crashes and serious _,,

Tire pressure monitoring system *
Applies to vehicles: with tire pressu re mon ito ring system
General notes _J
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 (TPMS) that illuminates a low tire
pressure tellta le when one or more of your tires is significantly
under-inflated. Accord ingly, when the low t ire pressure te llta le 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
failure . Under -inflation also reduces fue l efficiency and tire tread
life, and may affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte ­
nance, and it is the driver's responsibi lity 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 vehicle has also been equipped with a TPMS malfunction indi­
cator to indica te when the system is not opera ting proper ly . The
T PMS malfunction indicator is combined with the low tire pressure
t elltale. When the system detects a ma lfunction, the telltale w ill
flash for approximately one minute and then remain continuously illuminated. This sequence will continue upon subsequent vehicle
start-ups as long as the malfunction exists .
When the malfunction indicator is illuminated, the system may not
be ab le to detect or signa l low tire pressure as intended. TPMS
malfunctions may occur for a variety of reasons, inc luding the insta
llation of replacement or alternate tires or wheels on the
vehicle that prevent the TPMS from functioning properly . A lways
check the TPMS malfunction telltale after replac ing one or more
tires or whee ls on your vehicle to ensure that the replacement or
alternate tires and wheels allow the TP MS to continue to function
proper ly. •
App lies to veh ic les: w ith tire pressure monitoring system
Introduction
The tire pressure monitoring system monitors air pressure
in all four road wheels while the vehicle is moving .
As soon as the tire pressure monitor ing syste m senses a signi ficant
loss of air pressure in one or severa l tires, text messages and yellow
symbols appear in the ins trument c luster dis play to alert the d river .
The warning light in the instrument cluster comes on when the
t ire is sig nificantly unde rinflated
~ page 12 .
The warn ing light { also i lluminates in the case of a system
malfunction.
Be aware that tire p ressu re is also dependent on the tempe ra ture of
the tire . For every 18 °F (1 O °Cl increase in tire temperature, tire pres ­
su re increases by about 1 .5 psi (0 .1 bar). The ti re wa rms up wh ile the
vehicle is moving and tire pressure rises. So you should adjust tire pressure only when they are
cold, when the temperature of the tires
is roughly the same as the ambient air temperature.
I n order to keep the tire pressure monitoring system properly cali ­
brated, tire pressure on all fou r tires sh ould be checked at regular
interva ls, adjusted if necessary, and saved in the proper setting
(recommended pressure)~
page 265.
The tire pressure is shown either on the driver's side B-pil lar or on
the inside of the fuel filler f lap . _..
