.&_ WARNING
Please note the important safe­
ty precautions regarding tire pressure ¢
page 224 and load
limits¢
page 227.
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle
and any tire can carry . A vehicle
that is overloaded will not handle
well and is more difficult to stop .
Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout
and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas ­
sengers also depends on making
sure that load limits are not ex­ ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are
technically referred to as the vehi­ cle's
Gro ss Vehicle We ight Rating
("GVWR").
The "GVWR" includes the weight of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids
Tires and wheels
plus maximum load . The maxi­
mum load includes the number of
passengers that the vehicle is in ­
tended to carry ("seating capac i­
ty") with an assumed weight of
150 lbs . (68 kg) for each passen­
ger at a designated seating posi­
tion and the total weight of any luggage in the vehicle . If you tow
a trailer, the weight of the trailer
hitch and the tongue weight of
the loaded trailer must be includ­ ed as part of the vehicle load.
The
Gross Ax le Weight Rating
("GAWR") is the maximum load
that can be applied at each of the
vehicle's two ax les.
T he fact that there is an upper
limit to your vehicle's Gross Vehi ­
cle Weight Rating means that the
total weight of whatever is being
carried in the vehic le (inc luding
the weight of a trai ler hitch and
the tongue weight of the loaded
trailer) is limited. The more pas­
sengers in the vehicle or passen­
gers who are heavier than the
standard we ights assumed mean
that less weight can be carried as luggage.

& WAR NING
-
Overloading a vehicle can cause
loss of vehicle control, a crash
or other acc ident, serious per­
sonal injury, and even death.
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and in­ crease the risk of the 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 can fail sud­
denly, including a blowout and
sudden deflation, causing loss of control and a crash.
-Always make sure that the to­ tal load being transported -
inc luding the weight of a trail­
er hitch and the tongue
weight of a loaded trailer -
does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rating.
228
Determining correct load
limit
Use the example below to calcu­
late the total weight of the pas­
sengers and luggage or other
things that you plan to transport so that you can make sure that
your vehicle will not be overload ­
ed.
Step s for Determining Correct
Load Limit
1. Locate the statement "THE
COMBINED WE IGHT OF OCCU ­
PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
L BS"on your vehicle's placard
(tire inflation pressure label)
¢ page 224, fig . 170 .
2. Determine the combined
weight of the drive r and pas­
sengers that will be riding in
your vehic le.
3. Subtract the combined weight of the driver and passengers
from "XXX" kilograms or "XXX"
pounds shown on the sticker
¢ page 224, fig . 170 .
4. The resulting figure equals the
available amount of cargo and luggage load capacity . For ex­
ample, if the
"XXX" amount
equals 1400 lbs . and there will ...

,....,
be five 150 lbs. passengers in
your vehicle, the amount of
available cargo and luggage load capacity is 650 lbs.
(1400-750 (5
X 150) = 650
lbs.)
5. Determine the combined weight of luggage and cargo
being loaded on the vehicle.
That weight may not safely
ex­
ceed the available cargo and
luggage load capacity calculat­
ed in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer
will be transferred to your vehi­
cle. Consult this manual to de­
termine how this reduces the available cargo and luggage
load capacity of your vehicle.
.,.Check the tire sidewall
(c> page 214, fig. 168) to deter­
mine the designated load rating
for a specific tire.
Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/tighten
easily.
Rims
Rims with a bolted rim ring* or with bolted wheel
covers* consis t of mul tiple pieces. These compo­
nents were bolted together using special bolts
and a special procedure . You must not repair or
disassemble them
Q ,& .
Tires and wheels
A WARNING
Wheel bolts that are tightened or repaired in­
correctly can become loose and result in loss
of vehicle control, which increases the risk of
an accident . For the correct tightening specifi­
cation, refer to~
page 242, A~er changing a
wheel.
- Always keep the wheel bolts and the threads
in the wheel hub clean and free of grease.
- Only use wheel bolts that fit the rim.
-Always have damaged rims repaired by an
authorized Audi dealer or authorized Audi
Service Facility. Never repair or disassemble
rims yourself, because this increases the risk
of an accident.
Winter tires
Winter tires significantly improve the vehicle's
handling when driving in winter conditions. Be­
cause of their construction (width, compound,
tread pattern), summer tires provide less traction on ice and snow.
.. Use winter tires on all four wheels.
.. Only use winter tires that are approved for your
vehicle .
.. Please note that the maximum permitted
speed may be lower with winter tires
Q _& . An
authorized Audi dealer or authorized Audi Serv­
ice Facility can inform you about the maximum
permitted speed for your tires.
.. Check the tire pressure after installing wheels
Qpage 224.
The effectiveness of winter tires is reduced great­
ly when the tread is worn down to a depth of
0.157 inch (4 mm). The characteristics of winter
tires also decrease greatly as the tire ages, re­
gardless of the remaining tread.
A WARNING
-Never drive faster than the maximum per­
mitted speed for your tires. This could cause
the tires to heat up too much. This increases
the risk of an accident because it can cause
the tire to burst.
229

Tires and wheel s
-Always adapt your driving to the road and
traff ic conditions. Dr ive carefully and red uce
yo ur speed on icy or slippery roads. Even
winter tires can lose tract io n on black ice .
@ For the sake of the environment
Reinstall summer tires at the appropriate
time, because they provide better handling
when roads are free of snow a nd ice. Summer
tires cause less road noise, tire wear and fuel
consumptio n.
(D Tips
You can also use all season tires instead of
w inte r tires. Please note that in some coun­
t ries w here winter tires are requ ired, on ly win­
t er tire s wi th the .& symbol may be pe rm it­
t ed.
Snow chains
Snow chains improve traction in the snow .
.,. Only install snow chains on the front wheels.
Th is applies also to veh icles with all wheel
drive* .
.,. Ch eck and correct the seating of th e snow
c h ains if necessa ry afte r dri ving a few feet. Fo l­
l ow the ins tructions from the manuf acturer.
.,. Note t he max imum permit ted speed w hen driv ­
ing with snow chains . Do not exceed 30 mph
(SO km/h).
Snow chains not only improve the
driving in win ­
ter road conditions, but a lso t he
braking .
Use of s now chai ns is o nly pe rm itted with certa in
r im/t ire comb ina tion s due to techn ica l reason s.
Chec k w ith an au thori zed A udi d ealer or au tho r­
ized A udi Service Facility to see if yo u may use
snow cha ins.
Use
fine -mesh snow chain s. They mus t not add
mo re th an 0 .5 3 inch ( 13.S mm) in height, in clu d­
ing the chain lock.
You must remove the chai ns when dr iv ing on
roads tha t are
free of snow. W hen r oads are free
of snow, snow chains can imp air handling an d
230
'
damage the tires, and the chains wi ll quick ly be
dest royed.
A WARNING
Using incorrect snow chains o r insta lling snow
cha ins incor rectly can res ult in loss of veh icle
c o ntrol, which increases the risk of an acc i­
dent.
(D Note
- Snow chains can damage the rims/wheel
cove rs* if the c hains come into direct c on­
tact with them. Remove the wheel covers*
first . Use coa ted snow cha ins.
Low aspect ratio tires
Your A udi is fac to ry-eq uipped w ith low aspect ra­
t io t ires. These t ires have been thoroug hly tes ted
a nd been sele cted specifi ca lly f or your mode l for
the ir su perb pe rformance, r oad fee l and h andlin g
u nder a var iety of dr iv ing con ditions. As k your au ­
t h orized Aud i dea le r fo r more details .
The low aspe ct ratio of these tires is ind icated by
a n umer al of
55 or less in the t ire's s ize design a­
tion . The nume ral represents the ratio of the
ti re's si dewall height in relatio n to its tread width
expressed i n pe rcentage. Conventional tires have
a height/width rat io o f 60 o r more .
The performance of low-aspect-ratio tire s is par­
ticularly sensitive to imprope r inflation pres­
sure. It is therefore important that low aspect ratio tires are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained. Tire pressures should be checked at least once a month and always
b efor e a long trip
Q page 224 .
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged mo re eas i­
l y by impact w ith potho les, c urbs , g ull ies o r
r idges on t he road, pa rti cularly if th e tire is un ­
der i nflated.

In o rder to m inim ize the occu rrence o f impac t
damage to the t ires of your vehicle, we recom ­
mend that you observe the following precau ­
tions :
- Always maintain recommended in flat ion p res ­
s ur es . Check yo ur tire p ress ure every 2,000
miles (3,000 km) and add air if necessary.
- Drive carefu lly on roa ds with potholes, deep
gul lies or ridges. The impact from driving
th ro ugh or over such obstacles can damage
your tires. Impact with a curb may also cause damage to your tires.
- After any impact, immediately inspect your
tires or have them inspected by the nearest a u­
thorized Aud i dea ler . Replace a damaged tire as
soon as poss ible .
- Inspect your t ires every 2,000 miles (3 ,000 km)
for damage and wear. Damage is not always
easy to see. Damage can lead to loss of a ir and
underinflation, which cou ld eventually cause
t ir e fa il ur e.
If yo u be lieve that a ti re may h ave
been d amaged, rep lace the tire as soon as pos­
s ible.

All passenger car t ires must conform to Federa l
Safety Requirements in addition to these grades.
Tread wear
T he tread wear g rade is a comparative rating
based on the wear rate of the t ire when tested
u nder contro lled c onditions on a specified gov­
ernment test course.
F or example, a tire gra ded 15 0 wo uld wear one
and one half (1 1/2) times as we ll on the govern­
ment course as a t ire g raded 100.
T he re lative per forman ce of tires depends upon
t h e actual cond itions of thei r use, however, and
may depart significantly from the norm due to
variations in driv ing habits, service p ract ices and
differences in road c haracteristics and climate.
Traction
T he traction gra des, from highest to lowest, are
AA , A , Ban d
C. Those g rades represent t he tire's
ability to stop on wet pavement as meas ured un­

Temperature
The temperature grades are A (the highest), B,
and C, representing the t ire's resistance to the
generation of heat a nd its ability to diss ipate
heat when tested u nder cont ro lled conditions on
a spec ified indoor labora to ry test wheel.
Sustained h igh temperature can cause the mate­

Tires and wheels
The grade C corresponds to a level of perform­
ance which all passenger car tires must meet un­
der the Federal Motor Vehicle Safety Standard No.
109 . Grades Band A represent higher levels
of pe rformance on the laboratory test wheel than
the minimum required by law .
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla­
tion, or excessive loading, either separate ly or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not over or underinflat ­
ed .
Tire pressure monitoring
system
CD General notes
Applies to veh icles: w ith tire pressure monitoring system
Each tire, including the spare (if provided),
should be checked monthly when cold and inflat ­
ed to the inflation pressure recommended 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 pressure la­
bel, you should determine the proper tire infla­
tion 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 tell­
tale when one or more of your tires is significant ­
ly under-inflated. Accordingly, when the low tire
pressure telltale illuminates, you should stop and
232
check your tires as soon as possible, and inflate
them to the proper pressure . Driving on a signifi­
cantly under-inflated tire causes the tire to over­
heat and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread life,
and may affect the vehicle's handling and stop ­
ping ability .
Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsibility to maintain correct tire pressure, even if under-inflation has not reached the level
to trigger illumination of the TPMS low tire pres­
sure telltale.
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined with the low t ire
pressure tel ltale. When the system detects a
malfunction, the telltale will flash for approxi­
mately one minute and then remain continuously
illuminated. This sequence will continue upon
subsequent vehicle start -ups as long as the ma l­
function exists .
When the malfunction indicator is illuminated,
the system may not be able to detect or signal low tire pressure as intended. TPMS malfunctions
may occur for a variety of reasons, including the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the
TPMS malfunction telltale after replacing one or
more t ires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly .

tire pressures regu larly .
- Under certain conditions (such as a sporty
driving style, winter conditions or unpaved
roads), the pressure monitor indicator may
