plus maximum load. The maxi
mum load includes the number of
passengers that the vehicle is in
tended to carry ("seating capaci
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 A xle Weight Rating
("GAWR") is the maximum load
that can be appl ied at each of the
vehicle's two axles.
The fact that there is an upper
limit to your vehicle's Gross Vehi
c le Weight Rating means that the
total weight of whatever is being
carried in the vehicle (including
the weight of a tra iler 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 weights 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 accident, serious per
sonal in jury, and even death.
-Carrying more weight than
your vehicle was designed to carry will prevent the vehicle
from handling properly and increase 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 -
including 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 .

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 .
Steps for Determining Correct
Load Limit
1 . Locate the statement "THE
COMBINED WEIGHT OF OCCU PANTS AND CARGO SHOULD
NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle 's placard
(tire inflation pre ssure label)
c:::> page 244, fig. 206.
2. Determine the combined
weight of the driver and pas
sengers that will be riding in
your vehicle.
3 . Subtra ct the combined weight
of the driver and passengers
from
"XXX" kilograms or " XXX"
pounds shown on the sticker
c:::> page 244 , fig. 206 .
4. The re sulting figure equals the
available amount of cargo and luggage load capacity. For ex
ample, if the
"XXX" amount
equals 1400 lbs. and there will
248
be five 150 lbs. passengers in
your vehicle, the amount of available cargo and luggage load capacity is 650 lb s.
(1400-750 (5 X 150) = 650
lb s.)
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 ve
hicle. Con sult this manual to
determine how this reduces
the available cargo and lug gage load capacity of your vehi
cle .
~check the tire sidewall
(¢ page 234, fig. 204) to deter
mine the designated load rating
for a specific tire.

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 acc ident. For the correct tightening specifi
cation, refer to ¢
page 260, After changing a

rims yourself, because this increases the risk
of an accident.
Winter tires
W inte r ti res s ignificantly improve the vehicle's
h andling when driving in win ter condit ions . Be
cause of the ir constr uction (width, compound,
tread pattern), summer tires provide less trac
tion on ice and snow .
"'U se winter t ires on all fo ur wheels .
.. Only use winter t ires that are approve d for your
v ehicl e.
"' Please note that the maximum permitted
speed may be lower with winter tires¢.&_ . An
authorized Aud i dealer or au thori zed Aud i Serv
ice Fac ility can inform you about the maximum
permitted speed fo r your tires .
"' Check the tire press ure after installing wheels
¢page 244.
The effectiveness of winter tires is reduced great
l y when the tread is worn down to a depth of
0 .1 57 inch (4 mm). The character ist ics of winter
tires a lso de crease great ly as the tire ages, re
ga rdless of the remain ing tread.
WARNING
- Never drive faster than the maxim um per
mitted speed for your t ires. This cou ld cause
the tires to heat up too much. Th is increases
Wh eel s
the risk of an accident because it can cause
the t ire to burst.
- Always adapt your driving to the road and
traffic cond itions . Drive carefully and reduce
your speed on icy or slippery roads . Even
winter t ires can lose tract io n on black ice.
@ For the sake of the environment
Reinsta ll summer tires at the app ropr iate
time, beca use they prov ide better handling
when roads are free of snow and ice. Summer
tires cause less road no ise, tire wear and fue l
consumpt io n.
(D Tips
You can also use all season tires instead of
winter tires. Please note that in some coun
tries where winter tires are required, on ly
winter tires w ith the

Low aspect ratio tires
Your Aud i is factory -equipped with low aspect ra
tio tires. These t ires have been tho roughly tested

thei r supe rb per fo rman ce , road feel and handling
un der a va riety of d riving conditions . As k yo ur au
thor ized Audi dealer for mo re details .
T he low aspect ratio of these t ires is in dicated by
a nume ral of
55 or less in the tire's size desig na
tion . The numera l rep resents the rat io o f th e
tire's sidewall he ight in relat ion to its tread width
expressed in pe rcentage. Conventional tires have
a height/w idt h rat io o f 60 o r more .
The performance of low-aspect -ra tio tires i s par
ticularly sensitive to improper 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
before a long trip <=>
page 244.
What you can do to avoid tire and rim
damage
Low aspect rat io tires can be damaged more easi
ly by impact with potholes, cu rbs, gullies or
250
ridges on the road, particularly if the tire is un
derinflated.
I n orde r to mi nimize the occur rence o f imp act
dam age to the tires o f yo ur vehicle, we recom
mend that you observe the following preca u
tions:
- Always m aintain reco mmende d in fla tion pres
sures. Check yo ur tir e pressure eve ry 2,0 00
m iles (3,00 0 km) and add air if necessary .
- Dr ive c arefully on ro ads w ith potholes, deep
gu llies o r ridges . The impact from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may a lso ca use
damage to your t ires.
- After any impact, immediate ly inspect you r
tires or have them inspected by the nearest au
thorized Aud i dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 m iles (3,000 km)
for damage and wear . Damage is not always
easy to see . Damage can lead to loss of a ir and
unde rinflation, w hich could event ua lly cause
tire fa ilure . If you believe that a tire may have
be en damaged, replace the tire as soon as pos
sible .
- These tires may wear mo re quickly than o thers .
- Please also remember that, while these tires delive r responsive hand ling, they may ride less
comfortab ly and make mo re noise than o ther
choi ces.

For example: Tread wear 200 , Traction AA, Tem
perature
A .
All passenge r ca r tires m ust conform to Federal
Safety Requirements in add ition to these grades .
Tread wear
The tread wear grade is a comparat ive rating
based on the wear rate of the t ire when tested
under cont ro lled conditions o n a specified gov
e rnment test course.
For example, a t ire graded
1 50 would wear one
and one ha lf
( 1 1/2) times as well on the gove rn
men t course as a tire g raded
100.
The relative performance of t ires depends upo n
the actual conditions of their use, howeve r, and
may depart significant ly from the norm due to
va ria tions in driving ha bits, serv ice practices and
d ifferences in road cha racteristics and climate .
Traction
The traction grades, from highest to lowest, are
AA, A, B and
C. T hose grades represent the t ire's
ab il ity to stop on wet pavement as meas ured un

Wheels
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 overheat 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 tire pressure telltale. 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 mal
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 tires or wheels on your vehicle to ensure
that the replacement or alternate tires and
wheels allow the TPMS to continue to function
properly.
