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
c> page 303.
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.
Tires and wheels 285
-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 •

,&_ WARNING
Sudden tire failure can lead
to loss of control, 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 haz­
ard, they do not grip well on
wet roads and increase your
risk of "hydroplaning" and
loss 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 damaged even though
the damage cannot be seen
that can lead to sudden tire

recommend using only these
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

298 Tires and wheels
Sustained high temperature can cause the
materia l of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure<=>,& .
The grade C corresponds to a level of perform­
ance which a ll passenger car tires must meet
under the Federa l Motor Veh icle Safety Stand ­
ard No.
109. Grades Band A represent higher
levels of performance on the laboratory test
wheel than the minimum required by law.
A WARNING
The traction grade assigned to this t ire is
based on stra ight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplanin g or peak traction
characteristics.
A WARNING ,.,.____
The temperature grade for this tire is es­
tablished for a tire that is properly inflated
and not overloaded. Excessive speed, un­
derinflation, or excessive loading, either
separately or in combination, can cause heat buildup and possible tire fa ilure.
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, loca l governments
may require true winter or "snow" tires, those
with very deeply cut tread. These t ires 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 construct ion
type as the other tires on your ve hicle.
Your veh icle is equipped with all -wheel drive,
this will improve traction during w inter driv­
i ng, even with the standard tires. However, we
strongly recommend that you always equip all
four whee ls on your veh icle w ith correctly fit­
ted winter ti res or all-season tires, when win­
ter road conditions are expected. This a lso im- proves the vehicle's
braking performance and
reduces stopping distances.
Summer tires provide less gr ip on ice and
snow.
Winter tires (snow tires) must always be fitted
on all four wheels.
Ask your authorized Audi dealer or qualified
workshop for perm itted
winter tire sizes . Use
only rad ial winter t ires .
Winter tires lose their effectiveness when the
tread is worn down to a depth of
0.157 inch
(4 mm).
Only drive w ith w inter t ires under winter con ­
ditions. Summer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °() .
If you have a flat tire, see notes on spare
wheel<=>
page 291 .
Please always remember that winter tires may
have a lower speed rating than the tires origi­
nally installed on your vehicle at the time it
was manufactured. Please see
<=>page 294,
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 2 76) is
on the side wall of the t ire
c> page 291.
A WARNING ,.___
Winter tires have maximum speed limits
that may be lower than your vehicle's max­
imum speed. Always know the maximum
speed before driv in g off. Never drive faster
than the speed permitted for your specific
winter tires. This wi ll cause damage to the
tires leading to an accident and serious
personal injury to you and your passen­
gers.
A WARNING
'----
Driving faster than the maximum speed
for which the winter tires on your vehicle were designed can cause t ire failure in­
cluding a blowout and sudden deflation,

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 . •

302 Tire s and whee ls
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
warn ing if:
- the tire pressure in one or more tires is too
l ow,
- the tire has st ructural damage,
- the tire pressure was changed, whee ls rotat-
ed o r replaced but the TPMS was not reset
¢ page 303,
-the sp are tire* is mounted.
Warn ing symbo ls
RE Loss of pressure in at least one tire¢,&..
Check the tire or tires and rep lace or repa ir if
necessary . The
RE indicator light in the instru ­
ment cluster also illuminates
¢ page 14.
Check/correct the pressures of all four tires
and reset TPMS via MMI.
[m'El (T ire Pressure Monitoring System) Tire
pre ssure: System m alfunction!. If [m'El ap­
pears after switching the ignition on or while
driving and the
RE i ndicator light in the in­
strument cluster bli nks for approx imately one
minute and then stays on, there is a system
malfunction . Attempt to store the correct tire
pressure
¢ page 303. If the indicator light
does not tu rn off or if it t urn s on sho rtly
thereafte r, immediately d rive yo ur vehicle to
an a uthorized Audi dea ler or a uthorized repair
facility to have the malfunction corrected.
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.

@ Tips
-The tire pressure m onitoring system may
stop working when there is an ESC mal­
funct ion.
- Using snow chains may result in a system
malfunction.
- The tire pressure monitoring system on
your A udi was developed using t ires with
the "AO" or "RO" identification on the
tire sidewall
c:> page 291. We recom­
mend using these t ires.
Reset tire pressure monitoring system
If the tire pressure is adjusted, wheels are ro­
tated or changed, the TPMS must be reset via
MMI.
.. Before stor ing the new tire pressures, check
t h at the current pressures on all four t ires
correspond to the specified values and
adapt the p ress ures to the current load

Replacing light bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace burned
out bulbs for you.
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in
many cases, other parts of the car must first
be removed before you are able to get to the
bulb. This applies especially to the light bulbs
in the front of your car which you can only
reach through the engine compartment.
Sheet metal and bulb holders can have sharp
edges that can cause serious cuts, and parts
