& WARNING (continued)
crashes and serious personal injuries . Have worn or damaged tires
replaced immediately.
• 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
low speed.
Glossary of tire and loading terminology
Accessory weight
means the combined weight (in excess of those standard items
which may be replaced) of automatic transmission, power steering,
power brakes, power windows, power seats, radio, and heater, to
the extent that these items are available as factory-installed equip­
ment (whether installed or not).
Aspect ratio means the ratio of the height to the width of the tire in percent.
Numb ers of 55 or lower indicate a low sidewall for improved
steering response and better overall handling on dry pavement.
Bead
means the part of the tire that is made of steel wires, wrapped or reinforced by ply cords and that is shaped to fit the rim.
Bead separation means a breakdown of the bond between components in the bead.
Cord
means the strands forming the plies in the tire.
& WARNING (continued)
• Never mount used tires on your vehicle if you are not sure of
their "previous history." 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.
• If you notice unusual vibration or if the vehicle pulls to one side
when driving, always stop as soon as it is safe to do so and check
the wheels and tires for damage . •
Cold tire inflation pressure
means the tire pressure recommended by the vehicle manufacturer
for a tire of a designated size that has not been driven for more than
a couple of miles (kilometers) at low speeds in the three hour period
before the tire pressure is measured or adjusted .
Curb weight means the weight of a motor vehicle with standard equipment
including the maximum capacity of fuel, oil, and coolant, air condi­
tioning and additional weight of optional equipment.
Extra load tire
means a tire designed to operate at higher loads and at higher infla ­
tion pressures than the corresponding standard tire . Extra load tires
my be identified as "XL",
"xi", "EXTRA LOAD", or "RF" on the side ­
wall.
Gross Axle Weight Rating ("GAWR")
means the load-carrying capacity of a single axle system, measured
at the tire -ground interfaces .
Gross Vehicle Weight Rating ("GVWR"l
means the maximum total loaded weight of the vehicle.

measuring tire wear .
Uniform Tire Quality Grading
is a tire information system developed by the United States National
Highway Traffic Safety Adm inistration (NHTSA) that is designed to
help buyers make relative comparisons among tires. The UTQG is
not a safety rati ng and not a guarantee that a tire will last for a
prescribed number of miles or perform in a certain way . It simply
gives tire buyers additiona l information to comb ine with other
considerations, such as price, brand loyalty and dealer recommen- dations
. Under UTQG, tires are graded by the tire manufacturers in
t hree areas : treadwear, traction and temperature resistance. The
UTQG information on the tires, molded into the sidewalls.
U .S . DOT Tire Identification Number (TIN )
This is the tire's "seria l number" It begins with the letters "DOT" and
indicates that the tire meets a ll federal standards. The next two
numbers or letters indicate the plant where it was manufactured,
and the last four numbers represent the week and year of manufac ­
ture. For example,
DOT ... 2207 ...
means that the tire was produced in the 22th week of 2007. The
other numbers are marketing codes that may or may not be used by
the tire manufacturer. This information is used to contac t
consumers if a tire defect requires a reca ll.
Vehicle capacity weight
means the rated cargo and luggage load plus 150 lbs . (68 kilograms)
t imes the vehicle's tota l seating capacity as listed on the label
located either on the driver's side 8-pillar or on the inside of the fuel
filler flap.
Vehicle maximum load on the tire
means that load on an individual tire that is determined by distrib­
uting to each axle its share of the maximum loaded vehicle weight
and dividing by two.
Vehicle normal load on the tire
means that load on an individual tire that is determined by d istrib­
uting to each axle its share of the curb weight, accessory weight,
and normal occupant weight (distributed in accordance with table
below=>
page 317) and dividing by two. .,_

Bear in mind that the tire pressure monitoring system can only
monitor the tire pressures you have stored. The system does not
recognize the load condition of your vehic le.
The effectiveness of the tire pressure monitoring system will be impaired if you store normal load pressures but then operate the
vehic le at its maximum load=>&. See the
illustration=>

either on driver's side B -p illar or inside the fuel fi ller flap (color of
the actual label and exact location on the vehicle will vary slight ly).
Note that the fol lowing tab le is accurate at the time of going to
press and is subject to change . In the event of discrepanc ies, the tire
pressure label (on USA vehicles, the tire pressure label is located on
the dr iver's side B-pi llar; on Canada vehicles, the tire pressure labe l
is located either on the driver's side B-pillar or inside the fue l fi ller
fl ap) always takes precedence.

tant if the vehicle belongs to someone else or you bought the
vehicle with different rims/tires or you bought the vehicle as a previ ­
ously owned vehicle.
Remember, your safety and that of your passengers also depends
on making sure that load limits are not exceeded. Vehicle load
includes everybody and everything in and on the vehicle . These load
limits are technical ly referred to as the vehicle's Gross Vehicle
Weight Rating ("GVWR"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
either on the driver's side 8 -pillar or on the inside of the fuel fi ller
flap. The tire pressure labe l on your Audi lists the maximum
combined weight of a ll of the occupants and luggage or other cargo
that the vehic le can carry. For the location of the tire pressure label

Checking tire pressure
The correct tire pressure for the tires originally installed
on your vehicle is listed on the tire pressure label located
either on driver's side B-pillar or inside the fuel filler flap .
The recommended tire pressures are on the tire pressure label and
in the table~ page 317, "Cold tire inflation pressure". This means
that the pressure must be checked and adjusted when the tire has
not been driven for more than a couple of mi les (kilometers) at low
speeds during the previous three hours . Air in the tires expands
when the tire heats up as a result of internal fric tion as it flexes in
use. The tire pressure is higher when the tire has warmed up than
when it is "cold ."
It is the inflation pressure in a "cold" tire that counts . Therefore, you
should never let air ou t of a warm tire to match "Co ld tire inflation
pressure" recommendations~
page 317. The tires wou ld then be
underinflated and could fa il suddenly .
The tire pressure label on your Audi lists the recommended cold tire
inflation pressures for the new, original equipment tires that were
on your vehic le at the time it was manufactu red. For the location of
the labe l~
page 317, fig . 240.
Most tires lose air natural ly over time . They can a lso lose some air if
you drive over a pothole or hit a curb while parking. It is usually not ..,

& WARNING (continu ed )
• Only when all tires on the veh icle are filled to the correct pres­
s ure , the tire pre ssure monitoring sy stem can work correctly .
• The use of incorrect tire pressure values can lead to accidents
or other damage. Therefore it i s es sential that the driver observe
the specified tire pre ssure values for the tires and the correct pres­
s ures for the function of the tire pressure monitoring system.
• Alway s inflate tires to the recommended and correct tire pres ­
sure before driving off .
• Driving with underinflated tires bend more , letting them get
too hot re sulting in tread separation , sudden ti re failure and loss
of control.
• Ex cessive 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 tires 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 stat ion
to che ck the tire pressure and add air as required .
0 Note
Driving without valve stem caps can cause damage to the tire
valves. To preven t this, a lways make su re t hat facto ry instal led
va lve
stem caps on a ll whee ls are securely mounted on the va lve .
'£> For the sake of the environment
Underinflated t ires will a lso increase the fuel consumption. •
Tires and vehicle load limits
There are limits to the amount of load or weight that any vehicle and
any t ire can car ry. A vehicle that i s ove rlo aded wil l n ot hand le well and
is more difficu lt to stop . Overloading can not only lead to loss
o f ve h ic le control, but ca n also damage impor ta nt parts o f the
vehic le and can lead to sudden tire fa ilure, inc luding a blowout and
sudden defla tion that ca n cause the vehic le to cra sh .

that the vehicle can carry. For the location of the label~ page 31 7,
fi g. 240 .
& WARNING
Overloading a vehicle can cause loss of vehicle control , a crash or
other accident , serious personal injury, and even death.
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
ri sk of the loss of vehicle control.
• 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 overloaded can fail suddenly,
including a blowout 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 Rating. •
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and luggage or other things that you plan to
transport 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 OCCUPANTS AND CARGO SHOULD NEVER EXCEED XXX KG OR XXX
LBS"on your vehicle's placard (tire infla­
tion pressure label)=>
page 317 , fig. 240.
2. Determine the combined weight of the driver and passengers that will be riding
in your vehicle.
3 . Subtract the combined weight of the
driver and passengers from
"XXX" kilo ­
grams or
"XXX" pounds shown on the
sticker=>
page 317, fig. 240.
4. The resulting figure equals the available amount of cargo and luggage load capacity. For example, 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.) t,,,

Tires and wheels -_______________ _____.
5. Determine the combined weight of
luggage and cargo being loaded on th e
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 trailer will be transferred
to your vehicle. Consult this manual to determin e how this reduces the avail ­
able cargo and luggage load capacity of
your vehicle.
- Check the tire sidew all (~
page 325,
fig . 244) to determine the designated
load rating for a specific tire . •
