important parts of the vehicle
and can lead to sudden tire fail­
ure, including a blowout and
sudden deflation that can cause
the vehicle to crash.
Your safety and that of your
passengers also depends on
making sure that load limits are not exceeded. Vehicle load in­
cludes everybody and every­
thing in and on the vehicle.
These load limits are technical­ ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR").
The "GVWR" includes the
weight of the basic vehicle, all
factory installed accessories, a
full tank of fuel, oil, coolant and other fluids plus maximum
load. The maximum load in­
cludes the number of passen­
gers that the vehicle is intend­
ed to carry ("seating capacity")
with an assumed weight of 150 lbs . (68 kg) for each pas­
senger at a designated seating
position 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
Tires and wheels 225
must be included as part of the
vehicle load.
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 Rat­ ing and the Gross Axle Weight
Rating are listed on the safety
compliance sticker label locat­
ed on the driver's side 8-pillar.
Your Audi has 4 seating posi­
tions, 2 in the front and 2 in the rear for total seating capacity
of 4. Each seating position has
a seat belt¢ page 123, Safety
belts.
The fact that there is an upper limit to your vehicle's Gross Ve­
hicle Weight Rating means that
the total weight of whatever is being carried in the vehicle (in­
cluding the weight of a trailer hitch and the tongue weight of
the loaded trailer) is limited.
The more passengers in the ve­ hicle or passengers who are
heavier than the standard
weights assumed mean that less weight can be carried as
luggage.

Audi also lists the maximum
combined weight of all of the
occupants and luggage or other
cargo that the vehicle can carry. For the location of the label

A WARNING
-
Overloading a vehicle can
cause loss of vehicle control,
a crash or other accident, se­
rious personal injury, and
even death.
-Carrying more weight than your vehicle was designed to carry will prevent the ve­
hicle 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 vehi­
cle within a safe distance.
-Tires on a vehicle that has
been overloaded can fail
suddenly, including a blow­
out and sudden deflation,
causing loss of control and a
crash .
-Always make sure that the
total load being transported
- including the weight of a trailer hitch and the tongue
weight of a loaded trailer­ does not make the vehicle
heavier than the vehicle's
Gross Vehicle Weight Rat­
ing.
Determining correct load
limit
Use the example below to cal­
culate the total weight of the
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 217,
fig. 182.
2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.

"' N

3. Subtract the combined weight of the driver and pas­sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
.:::> page 217, fig. 182.
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
cle, the amount of available
cargo and luggage load ca­
pacity 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
exceed the available cargo
and luggage load capacity
calculated in Step 4.
6. If your vehicle will be towing
a trailer, load from your trail­
er will be transferred to your
vehicle. Consult this manual
to determine how this re­
duces the available cargo
and luggage load capacity of
your vehicle .

Tire service life
The service life of tires depends
on a lot of different things in­
cluding proper installation and
balancing, correct tire pressure
and driving style.

rebalanced when a new tire is
installed.
Incorrect wheel alignment
Incorrect wheel alignment can
cause excessive tire wear, im­
pairing the safety of the vehi­
cle. If tires show excessive
wear, have the wheel alignment checked by an authorized Audi
dealer or qualified workshop.
All wheel drive
Vehicles with quattro must al­
ways have tires of the same
size, construction and tread
type. For details see
¢page 176.
A WARNING
Sudden tire failure can lead
to loss of control, 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 haz­
ard, they do not grip well on
wet roads and increase your risk of "hydroplaning" and
loss of control.
Tires and wheels 229
-Always keep chemicals that can cause tire damage, such
as grease, oil, gasoline and
brake fluid away from tires.
-Tires age even if they are not being used and can fail
suddenly, especially at high speeds. Tires 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 damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.

We recommend that all work
on tires and wheels be per­

have the necessary special tools
and spare parts as well as the
proper facilities for disposing of
the old tires.

Replacing tires and wheels
Tires should be replaced at least in pairs and not individu ­
ally (for example both front
tires or both rear tires togeth­ er) .
Be sure to read and heed the in­
formation to the tire pressure monitoring system*
¢page 239.
Always buy replacement radial
tires that have the same specifi­
cations as the tires approved
for your vehicle by Audi. Re­
placement tires must always
have the same load rating spec­

(r=>page 217, fig. 183) lists the
specifications of the original
equipment tires installed on
your vehicle at the time it was
manufactured.
Federal law requires tire manu­
facturers to place standardized information on the sidewall of
all tires¢
fig. 186. This infor­
mation identifies and describes
the fundamental characteris­
tics, the quality grade of the
tire and also provides a tire identification number for safety
standard certification and in
case of a recall.
Tire specifications
Knowledge of tire specifications
makes it easier to choose the
correct tires. Radial tires have
the tire specifications marked on the sidewall , for example:
