General notes
Tires may be the least appreciated and most
abused parts of a motor vehicle .
Tires may be the least appreciated and most
abused parts of a motor vehicle . Tires are,
however, one of the most important parts of a
vehicle, particularly considering the compara­
tive ly small patch of rubber on each tire that
assures that a ll-impo rtant contact between
you, your vehicle and the road.
Maintaining the correct tire pressure, mak ing
sure that your vehicle and its tires do not have
to carry mo re weight than they can safe ly han­
d le, avoiding damage from road hazards and
reg ularly inspecting t ires for damage includ­
ing cuts, slashes irregu la r wear and ove rall
condition are the most important things that
you can do to he lp avoid sudden tire failure in­
cluding tread separation and blowouts.
Avoiding damage I f you have to drive over a curb or similar ob­
stacle, drive very s low ly and as close as possi ­
b le at a right angle to the curb.
A lways keep chem ica ls includ ing gre ase, o il,
gasoline and b rake fluid off the ti res .
Inspect the t ires regularly for damage (cuts,
cracks or b listers, etc.). Remove any fo reign
bod ies embedded in the treads.
Storing tires Mark tires when you remove them to indicate
the direction of rotation . Th is ensures you to
be ab le to mount them correctly when you re­
install t hem.
When removed, the whee ls or t ires should be
stored in a cool, d ry and preferably dark place .
Store tires in a vertical pos ition if they are not
mounted on rims, in a horizontal pos it ion if
they are mounted on rims. New tire
s
New t ires have to be broken in¢&,. .
T he tread depth of new t ires may vary, accord­
ing to the type a nd make of t ire and the tread
pa tte rn .
Hidden damage
Damage to tires and r ims is ofte n not readily
vis ible . If you notice unusual v ibrat ion or the
vehicle p ulls to one side, th is may ind icate
t h at one of the t ires has been damaged . Th e
t ir es m ust be checked immed iate ly by an au ­
tho rized Aud i dea le r or q uali fied wor ks hop.
Unidirectional t ires
A un idirectional tire can be identified by ar­
rows on the sid ewa ll, that po int in the direc­
t ion the t ire is desig ned to rotate. You mus t
f ol low the specified d irection of rotation . This
is necessary so that these tires can develop
their optimum characterist ics regarding grip,
road no ise, wear and hyd rop laning resistance.

A WARNING
-New tires or tires that are old, worn or
damaged cannot provide maximum con­
trol and braking ability .
-
-New tires tend to be slippery and must
also be broken-in. To reduce t he risk of
losing control, a collision and se rious
pe rsonal injuries, drive w it h specia l care
for the first 350 miles (560 km).
- Driving with worn or damaged tires can
le ad to loss of control, sudden tire fail­
ure, including a blowou t and sudden de­
fl ation, c rashes and seriou s personal in­
juries . Have wo rn or damaged t ires re­
p laced immediate ly .
- T ires age even if they are not being used
an d can fai l sudden ly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then w ith specia l care and at low
speed.

Because technical changes may be made to
vehicle equ ipment dur ing the model year, a l­
ways compare the tire s ize designation on the
tire pressure label on your vehicle w it h the
tires on your veh icle. Ma ke sure that the tire
size info rmation on the ve hicle label is the
s a me as the s ize of the t ires on the vehicle.
This is especia lly important if the vehicle be­
l ongs to someone else or you bought the vehi­
cle with different rims/tires o r you bought the
vehicle as a previously owned vehicle.
Remember, your safety and that of your pas ­
sengers also depends on mak ing su re that
l oad limits a re 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 G ross Vehicle We ight Rat
ing ("GVWR"). The Gross Axle We ight Rat­
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weig ht Rating are listed on the
sa fe ty comp liance sticke r label lo cated e ither
on the dr iver's s ide B-pillar or on the ins ide of
the fue l filler flap. The tire pressure labe l on
your A udi lists the maximum combined
weight of all of the occ upants and luggage or
other cargo that the veh icle can carry . For t he

A WARNING
Overloading a vehicle can cause loss of ve­
h icle cont ro l, a c rash or other accide nt, se­
rious pe rsonal injury, and even death.
- Ca rrying more we ight than your veh icle
was des igned to carry will prevent the

vehicle from handling properly and in­
crease 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 overload­ ed can fail suddenly causing loss of con­
tro l and a crash.
- Always make sure that the tota l load be­
ing transported -including the weight of
a tra iler hitch and the tongue weight of a
loaded trailer -does not make the veh i­
cle heav ier than the veh icle's Gross Vehi­
cle Weight Rating.
_& WARNING
- Incorrect 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/or underin­
flation can also lead to sudden tire fai l­
ure, including 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 either on driver's side 8-pillar or inside the fuel filler flap.
The recommended tire pressures are on the
tire pressure labe l and in the tab le
¢ page 256, 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 .
A ir in the tires expands when the tire heats up
as a result of inte rna l fr iction as it flexes in
use. The ti re p ress ure is higher when the tire
has warmed up than when it is "cold."
It is the inflat ion pressure in a "cold" tire that
counts. Therefo re, you should never let air out of a warm tire to match "Cold tire
inflation
pressure" recommendations ¢
page 256. The
t ires wo uld then be underinf lated and co uld
fail suddenly.
The tire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
maximum capacity for the new, orig inal
equipment tires that were on your vehicle at
the time it was manufactured. For the loca­
t ion of the labe l
¢page 256, fig . 210 .
Most tires lose air natura lly over t ime. They
can a lso lose some air if you drive over a pot­
hole or hit a curb while park ing. It is usually
not possible to see whether the rad ial tires
used today are underinflated just by look ing
at them.
Therefore, be sure to check t ire pressures at
least once a month and a lways before going
on a long trip . Make sure to take the number
of peop le and the amount of luggage into ac­
count when adjust ing ti re pressu re for a trip -
even one that yo u wou ld not consider to be
" long." See
¢ page 260, Tires and vehicle
load limits
for mo re important information.
Always use an accurate tire p ressu re ga uge
when checking and ad justing inflat ion pres­
sures . Check a ll of the tires and be s ure not to
forget the spare tire. If the pressure in any tire
is too high when the tire is "cold," let air o ut
of the tire s low ly 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 k ind of
dr iv ing you plan to do .
If the pressure in any tire is too low, note the
difference between the pressure in the co ld
t ire 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 vehi cle as listed on the on
yo ur vehicle and in th is m anu al and the kind
of d riving you plan to do.
Ne ver e xceed th e maximum infl ation pre s­
sure lis ted o n the tir e side wall for any rea ­
s on.

Remember that the vehicle manufacturer, not
the tire manufacturer, determines the correct
tire pressure for the t ires on your vehicle .
It is importan t to check the tire pressu re when
the t ires a re cold .
- Read the requ ired ti re p ressure from the tire
pressure label. On USA veh icles, the t ire
pressure label is located on the drive r's side
B-pi llar . On Canada vehicles, the tire pres ­
s u re label is located either on the driver's
s ide B-pi llar or inside the fue l filler flap . The
t ire press ure label lists the recommended
cold tire inflation pressures for the veh icle
at its max imum capacity weight and the
t ires that were on your vehicle at the time it
was manufactured . Fo r recommended t ire
pressures fo r normal load condit ions, please
see chapter
9page 256.
- T urn the valve stem cap counter-clockwise
to remove it from the tire valve .
- Place the air pressu re ga uge on the valve .
- The tire pressures should only be checked
and adjusted when the tires a re cold . The
s li ghtly raised p ressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you a re
c a rrying.
- Re install the valve stem cap o n the valve .
When should I check the ti re pres sure ?
The correct tire pressure is espec ially impor­
tant at high speeds. The pressure should
therefore be checked at least once a month
and a lways befo re start ing a journey . Do not
forget to check the tire pressure for the spare
wheel.
When should I ad ju st the tire p re ss ures?
Adjust the tire pressure to the load you are
carry ing . After chang ing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition , you must then in it i­
alize the new tire pressures in the tire pres­
sure mon itor ing system*

_& 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
ti] warn ing symbol 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

- T he drive r is responsi ble for the co rrec t
tire pressures for all tires on the veh icle.
The appli cable pressure values a re locat ­
ed on a sticke r on the dr iver's side B -pil­
lar or on the inside of the fuel filler flap.
- 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 ress ure monito r­

Driving without va lve stem caps can cause
damage to the tire va lves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are secure ly
mounted on the valve .
@I For the sake of the environment
Underinflated tires will also increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry.
A vehicle that is ove rloaded w ill not ha ndle
well and is more difficult to stop. Over load ing
can no t on ly lead to loss of vehi cle contro l,
but can also damage important pa rts of the
ve hicle and can lead to sudden tire failure, in­
cluding a blowout and sudd en deflation that
can cause the veh icle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making s ure that load limits are
not exceeded . Vehicle load includes everybody
and everyth ing in and on the vehicle . These
load limits are techn ically referred to as the
ve hicle's
Gross Veh icle W eight Rat ing
(" GVWR ").
T he "GVWR" incl udes the we ight of the basic
vehicle, all f actory installed accessories, a full
tank of fuel, oil, coolant and other fluids plus maximum load . T he maximum load includes
the number of passengers that the vehicle is in tended to carry ("seating capacity") with a n
assumed weig ht of 150 lbs . (68 kg) for e ach
passenger at a des igna ted seat ing pos ition
and the tota l we ight of any l uggage in the ve ­
h icle. If you tow a trailer, the weight of the
tra iler hitch and the tong ue weight of the
loaded trailer must be included as part of the
ve hicle load . T
he
Gro ss Axle We ight Rating ("GAWR") is
the maximum load that can be applied at each
of the veh icle's two axles .
T he Gross Vehicle Weigh t Rat ing and the
G ross Ax le Weight Rating are listed on the
safety comp liance sticker label located either
on the dr iver's s ide B-pillar or on the ins ide of
the fuel fi ller flap . Audi has
4 seating pos i­
t ions, 2 in the front and 2 in the rear for to tal
seat ing capac ity of 4 . Each seating position
has a seat belt ¢
page 154, Safety belts.
The fact that there is an upper limit to yo ur
vehicle 's Gross Vehicle Weight Rating means
that the total weight of whatever is being car­ ried in the vehicle ( includ ing t he weight of a
t railer hitch and the tongue weight of the
l oaded tra ile r) is lim ited. The more passen­
gers in the vehicle or passengers w ho are
heavier tha n t he standard we ights assumed
mean that less weight can be carried as lug ­
gage.

A WARNING
-Overloading a vehicle can cause loss of ve-
h icle contro l, a crash or other accident, se­
rious pe rsonal injury, and even death .
- Carrying more we ight than your veh icle
was des igned to carry will prevent the
veh icle from handling properly and in­
crease the risk of the loss of vehicle con­
trol.
- The b rakes on a vehicle that has been
overloaded may not be abl e to stop the
veh icle w it hi n a safe distance .
- Tires on a vehicle that has been overload­
ed can fail s udden ly, incl uding a blowo ut
a nd sud den defla tion, causing loss of
con trol an d a crash.
- Always make sure that the total load be­

A WARNING
Sudden tire failure can lead to loss of con­
trol, 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 hazard, 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 t ires.
- Tires age even if they are not be ing used
and can fail suddenly, especially at high
speeds . Tir es 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 dam­
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss of vehicle control.

This is the t ire's "serial number". It begins
with the lette rs "DO T" and indicates that the
tire meets all federal standards . The next two
numbers or letters indicate the p lant where it
w as manufactured, and the last four numbers
represen t the week and ye ar of manufacture .
For example, the numbers 2209 mean that
the t ire was produced in the 22nd week of
2009 . The othe r numbe rs are marketing co­

ted w inter t ires or al l-season t ires, when win­
te r road cond itions ar e expected . This also im­
proves the veh icle's b ra ki ng perfo rman ce and
reduces stopping d ista nces .
Summe r tires p rovide less grip on ice and
snow .
Winter tires (snow tires) must always be fitted
o n all four wheels .
Ask your authorized A udi dealer or qualified
workshop for permitted
winter tire sizes . Use
only rad ial winter t ires.
Winter tires lose their effectiveness whe n the
tread is worn down to a depth of
0.157 inch
(4 mm).
Only drive with winter tires under winte r con ­
ditions. S ummer t ires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °().
