Because tec hnical changes may be made to
vehicle equ ipment dur ing the model yea r, al­
ways compare the tire size designation on the
tire pressure labe l on you r vehi cle w it h the
tires on your vehicle. Ma ke s ure that the ti re
size information on the veh icle label is the
same as the size of the tires on the vehicle.
This is especially important if the vehicle be­
longs to someone else or you bought the vehi­
cle with different rims/tires or you bought the
vehicle 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
vehicle . These load lim its are technically refer­
red to as the vehicle's G ross Vehicle We ight
Rati ng ("GVWR"). The G ross Ax le Weight Rat­
i ng ("GAWR") is the max imum load that can
be app lied at each o f the veh icle's two axles.
The G ross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance stic ker labe l located either
on the driver's side B-pillar. The tire pressure
labe l on your Audi lists the maximum com­
b ined weight of all of the occupants and lug­
gage or other cargo that the veh icle can carry.

.&_ WARNING
Overloading a vehicle can cause loss o f ve­
h icle cont ro l, a crash o r other accident, se ­
r ious pe rsonal injury, and even death.
- Ca rrying more we igh t than your veh icle
was designed to car ry wi ll prevent the
vehicle from handling properly and 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 over load­
ed can fail s uddenly caus ing loss of con­
trol and a crash.
.&_ WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious or fatal acci­
dent.
- Inco rrect tire pressures and/or underin­
f lation cause increased tire wear and can
affect the handling of the vehicle.
- Inco rrect tire pressures and/or underin­
f lation can a lso lead to s udden t ire fail­
ure, including a blowout and sudden de­
fl ation, ca using loss of veh icle cont ro l.

The Gross Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating are listed on the
safety compliance sticker labe l located on the
driver's side B-pi llar . Your Audi has 2 seating
positions in the front for total seat ing capac i­
ty of 2. Each seating posit ion has a safety belt
c::> page 101, Safety belts.
The fact that there is an upper limit to your
ve hicle's Gross Veh icle Weight Rating means
that the total weight of whatever is being car­
ried in the veh icle is limited . The more passen­
gers in the veh icle or passengers who a re
heavier than the standard weights assumed
mean that less weight can be carried as lug­
gage.
The t ire pressure label on your Audi also lists
the maximum combined we ight of all of the
occupants and luggage o r othe r cargo that
the vehicle can carry. For the location of the
la be l c::>page 187, fig. 148.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
r ious personal injury, and even death.
- Carrying more weight than yo ur vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of the loss of veh icle con­
trol.
- The brakes on a veh icle 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, includ ing a b lowout
and sudden deflation, causing loss of
control and a crash.
Determining correct load limit
Use the example below to cal­
culate the total weight of the
Tires and wheels 191
passengers and luggage or oth­
er things that you plan to trans­
port so that you can make sure
that your vehicle will not be
overloaded.
Steps for Determining
Correct Load Limit
1. Locate the statement "THE
COMBINED WEIGHT OF OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi­
cle's placard (tire inflation
pressure label)
¢ page 187,
fig. 148.
2. Determine the combined weight of the driver and pas­
sengers that will be riding in
your vehicle.
3. Subtract the combined
weight of the driver and pas­
sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢ page 187, fig. 148.
4. The resulting figure equals
the available amount of car­
go and luggage load capaci-
ty. For example, if the
"XXX"
amount equals 1400 lbs.
and there will be five 150
lbs. passengers in your vehi­
c le, the amount of available .,..

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.

the wheel bolts. These are available from au­
thorized Audi dealers.
A WARNING
Using the wrong snow chains for your vehi­
cle or installing them incorrectly can in­
crease the risk of loss of control leading to
serious personal injury.
- Snow chains are available in different
sizes. Always make sure to follow the in­
structions provided by the snow chain
manufacturer .
- When driving with snow chains, never
drive faster than the speed permitted for
your specific snow chains.
- Always observe local regulations.
- Remove snow chains before driving on
roads not covered with snow to avoid
damaging tires and wearing the snow
chains down unnecessarily.
- Snow chains, which come into direct con­
tact with the wheel rim, can scratch or
damage it. Therefore, make sure that the
snow chains are suitably covered . Check
the position of the snow chains after
driving a few yards and correct if neces­
sary. Follow the instructions from the
snow chain manufacturer when doing so.
(D Tips
Where snow chains are mandatory oncer­
tain roads, this normally also applies to ve­
hicles with all-wheel drive.
Wheel bolts
Wheel bolts must always be tightened to the
correct torque.
The design of wheel bolts is matched to the
factory installed rims. If different rims are fit­
ted, the correct wheel bolts with the right
length and correctly shaped bolt heads must
be used. This ensures that wheels are fitted
securely and that the brake system functions
correctly .
Tires and wheels 199
In certain circumstances, you may not use
wheel bolts from a different vehicle -even if it
is the same model
r:!> page 221.
A WARNING
Improperly tightened or maintained wheel
bolts can become loose causing loss of
control, a collision and serious personal in­
jury.
- Always keep the wheel bolts and the
threads in the wheel hubs clean so the
wheel bolts can turn easily and be prop­ erly tightened.
- Never grease or oil the wheel bolts and
the threads in the wheel hubs. They can
become loose while driving if greased or
oiled, even if tightened to the specified
torque.
- Only use wheel bolts that belong to the
rim being installed.
- Never use different wheels bolts on your
vehicle.
-Always maintain the correct tightening
torque for the wheel bolts to reduce the
risk of a wheel loss. If the tightening tor­
que of the wheel bolts is too low, they
can loosen and come out when the vehi­
cle is moving.
If the tightening torque is
too high, the wheel bolts and threads
can be damaged and the wheel can be­
come loose.
(D Note
The specified torque for the wheel bolts is
90 ft lb (120 Nm) with a tolerance of ± 7 .4
ft lb( ± 10 Nm). Torque wheel bolts diago­
nally. After changing a wheel, the torque
must be checked as soon as possible with a
torque wrench -preferably by an author­
ized Audi dealer or qualified workshop.
Low aspect ratio tires
Your Audi is factory-equipped with low aspect
ratio tires. These tires have been thoroughly
tested and been selected specifically for your model for their superb performance, road feel
and handling under a variety of driving

Improper maintenance, adjustments and re­
pa irs can impair the operation and reliab ility
of your vehicle and even void your vehicle war­
ranty. Therefore, proof of servic ing in accord­
ance w ith the ma intenance schedule may be a
condition for upholding a poss ible warranty
claim made within the warranty period.
Above all, operational safety can be adversely
affected, c reating unnecessary risks for you
and your passengers.
If in doubt about any se rv icing, have it done
by your author ized Audi dealer or any other
p roperly equipped and qualified workshop.
