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 separat ion 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 r ims, 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 s ide, 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 s id 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 o ld, 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.

ways compare the tire s ize designation on the
tire pressure label on your vehicle w ith the
tires on your vehicle . Make s ure that the tire
size information on the vehicle label is the
same as the s ize of the t ires on the vehicle.
This is especially important if the vehicle be
longs to someone else or you bought the veh i
cle with different rims/tires or you bought the
veh icle as a previously owned vehicle.
Remember, your safety and that of your pas
sengers also depends on mak ing sure that
load limits are not exceeded . Vehicle load in
cludes everybody and everything in and on the
ve hicl e. These load limits are technically refer
r ed to as the vehicle's G ross Vehicle We ight
Rating ("GVWR"). The Gross Ax le Weight Rat
ing ("GAWR") is the maximum load that can
be applied at each of the vehicle's two axles .
The Gross Vehicle We ight Rating and the G
ross Ax le Weig ht Rating are listed on the
sa fe ty comp liance sticke r label lo cated on the
dr iver's side B-pillar . The tire pressu re labe l on
your A udi lists the maximum combined
weight of all of the occ upants and luggage o r
other cargo that the veh icle can carry. For the
location of the t ire pressure label ¢

A WARNING
-Overloading a vehicle can cause loss of ve-
h icle contro l, a crash or other accide nt, se
rious personal 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 a nd in
crease the risk of a loss of vehicle con
trol.
- The brakes on a vehicle that has been
overloaded may not be able to stop the
veh icle w ith in a safe distance.

-Tires on a vehicle that has been overload
ed can fail suddenly causing loss of con

- 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

A 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 c an also lead to sudden tire fa il
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 lis ted on the tire
pressure label located on driver 's side 8-pil
lar.
The recommended t ire p ress ures are on the
tire pressure labe l and in the tab le
¢ page 226, Cold tire inflation pressure. This
means that the pressure must be checked and
ad justed when the tire has not been driven for
more than a couple of m iles (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 w hen the tire
has wa rmed up than when it is "cold ."
It is the inflat io n pressure i n a "cold " tire that
counts . Therefore, you shou ld never let air out
of a warm t ire to match "Cold tire inflation
p ress ure" recommendations ¢
page 226. The
tires would then be under infla ted and cou ld
fa il suddenly . T
he tire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
maximum capacity for the new, or ig inal
equipment tires that were on your vehicle at
the time it was manufactured. For the loca
t ion of the labe l
¢page 226, fig . 185 .
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.
Therefo re, be sure to check t ire press ures at
least once a mo nth and a lways befo re going
on a long trip . Make sure to take the number
of peop le and the amou nt of luggage into ac
c ount w hen adjust ing ti re pressu re for a trip -
even one th at yo u wo uld not consider to be
" long." See
r:!v page 230, Tires and vehicle
load limits
for mo re important information.
Always use an accurate ti re p ressu re ga uge
whe n checking and ad justi ng i nflat ion pres
s u res . Check a ll of the tires. If the press ure in
any tire is too high when the tire is "cold", let
air out of t he tire slowly with the edge of the
t ire ga uge and keep checking the pressure un
t il you reach the pressure that is correct for
the load (passengers and luggage) and kind of
driv 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
t h at you need to reach the correct pressure for
the ve hicle load (passengers a nd luggage) for
the tires on your vehicle as listed on the on
you r vehicle and in this ma nual a nd the kind
of d riving you plan to do.
Ne ver e xceed the maximum inflation pres
sure listed on the tir e sidewall for any rea
son.
Remember that the vehicle manufacture r, not
the tire manufacturer, determines the cor rect
t ire p ressu re for the tires on your vehicle.
I t is impor tant to check the t ire pressure when
the tires are co ld .
111>
-Read the requir ed tire pressure from the tire
pressure label. The tire pressure label is lo
cated on the driver's side B-pillar. The tire
pressure label lists the recommended cold
t ire inf lation pressures for the vehicle at its
maximum capacity weight and the tires that
were on your vehicle at the time it was man
ufactured . For recommended tire pressures
for normal load conditions, please see chap
ter ~
page 226.
- Turn the valve stem cap counter-clockwise
to remove it from the tire valve.
- Place the air pressure gauge on the valve .
- The tire pressures should only be checked
and adjusted when the tires are cold . The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carry ing.
- Reinstall the valve stem cap on the valve .
When should I check the tire pressure?
The correct tire pressure is especially impor
tant at high speeds. The pressure should
therefore be checked at least once a month
and always before starting a journey .
When should I adjust the tire pressures?
Adjust the tire pressure to the load you are
carry ing. After changing a wheel
or replacing
wheels you have to adjust the tire pressures
on all wheels. In addition, you must then initi
alize the new tire pressures in the tire pres
sure monitoring system*~
page 240.
A WARNING
Incorrect tire pressures and/or underinfla
tion can lead sudden tire failure, loss of
control, collision, serious personal injury
or even death.
- When the
[9] warning symbol appears in
the instrument cluster, stop and inspect
the tires.
- Incorrect tire pressure and/or underinfla
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping ability.
Tires and wheels 229
- Incorrect tire pressures and/or underin
flation can also lead to sudden tire fail
ure, including a blowout and sudden de
flation, causing loss of vehicle control.
- The driver is responsib le for the correct
tire pressures for all tires on the vehicle.
The applicable pressure values are locat
ed on a sticker on the driver's side B-pil lar.
- Only when all tires on the vehicle are fil
led to the correct pressure, the tire pres
sure monitoring system* can work cor
rectly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the driver
observe the specified tire pressure values
for the tires and the correct pressures for
the function of the tire pressure monitor ing 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 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 t ires 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 sta
tion to check the tire pressure and add
air as required.
(D Note
Driving without valve stem caps can cause
damage to the tire valves. To prevent this,
always make sure that factory installed
valve stem caps on all wheels are securely
mounted on the valve.

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 overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not only lead to loss of vehicle control, but can also damage important pa rts of the
vehicle and can lead to s udden tire failure, in
cluding a blowout and sudden deflation that
can cause the vehicle to crash.
Your safety and that of your passenge rs a lso
depends on making s ure that load limi ts are
not exceeded . Vehicle load includes everybody
and everything in and on the vehicle. These
load limits are technica lly referred to as the
vehicle's
Gross Veh icle We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of f uel, oi l, coo lant and other fluids pl us
maximum load. The maximum load includes
the number of passengers that the vehicle is intended to carry ("seating capacity") with an
assumed weight of 150 lbs . (68 kg) for each
passenger at a des ignated 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 o f the
trai ler hitch and the tong ue weight of the
loaded trailer must be included as part of the
vehicle load.
The
Gro ss Axl e W eight Rating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles.
The G ross Vehicle Weight Rating and the
Gross Axle Weigh t Rating are listed on the
safety compliance sticker labe l located on the
driver's side B-pi llar . Audi has 4 seati ng posi
tions, 2 in the front and 2 in the rear for tota l
seating capacity of 4 . Each seating position
has a seat belt¢
page 129, Safety belts.
T he fact that there is an upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is being car ried in the vehicle ( includ ing the weight of a
trailer hitch and the tongue weight of the
loaded tra iler) is lim ited . The more passen
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mea n tha t less we ight can be carried as lug
gage.
T he t ire pressure label on your Aud i also lists
the max imum combined weig ht of a ll of the
occupants and luggage or other cargo that
the vehi cle can carry . For the location of the

- 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

Traction
The traction grades, from highest to lowest,
a re AA, A, Band
C. Those grades represent the
tire's ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance¢ .&..
Temp eratu re
The temperature grades are A (the highest),
B, and
C, representing the tire 's resistance to
the generat ion of heat and its ability to dissi
pate heat when tested under controlled condi
tions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failu re ¢ .&. .
The grade C corresponds to a level of perform
ance which all passenger car tires m ust meet
u nder the Federa l Motor Ve hicle Safety Stand
ard No. 109. Grades Band A represent higher
l eve ls of pe rformance on the laboratory test
wheel than the m inimum required by law.
_& WARNING
Th e traction grade assigned to this tire is
based on stra ight-ahead b raking t raction
tests, and does not include acceleration,
cornering , hydrop laning or peak traction
character istics.
A WARNING
The temperature grade for this t ire is es
tablished for a t ire that is properly inflated
and not overloaded. Excessive speed, un
derinflation, or excessive loading, either
separate ly or in combination, can cause
heat buildup and possibl e tire fa ilu re.

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 w inter o r "snow" tir es, those
with very deeply cut t read. These tires should
o nl y be used in pairs and be installed o n all
f o ur wheels . Make sure you p urchase snow
ti res that are the same size and cons truc tion
type as the other tires on yo ur vehicle .
You r vehi cle is equipped wi th a ll w heel d rive,
th is w ill imp rove trac tion duri ng win ter driv
ing, even with the standa rd tires. However, we
strong ly recommend that you always equip all
fo ur wheels on your vehicle with correctly fit
ted winter tires or a ll-season tires, when win
ter road cond itions are expected. This also im
proves the veh icle's brak ing performance and
reduces stopping d ista nces .
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
o n all fo ur whee ls .
As k your au thori zed A udi d ealer or qualified
workshop for permit ted
