If you wish to improve comfort
when operating the vehicle at
normal load (up to 2 occu­
pants), you can adjust tire
pressures to those specified
for normal vehicle load. Before
operating the vehicle at maxi­ mum load, you must increase
the tire pressures to those
specified for maximum vehicle
load
c> .&. .
Bear in mind that the tire pres­
sure monitoring system* can
only monitor the tire pressures
you have stored. The system does not recognize the load
condition of your vehicle.
The effectiveness of the tire p ressure monitoring system*
will be impaired if you store normal load pressures but then
operate the vehicle at its maxi­
mum load

220 Tires and wheels
Because technical changes may
be made to vehicle equipment
during the model year, always
compare the tire size designa­
tion on the tire pressure label
on your vehicle with the tires on
your vehicle. Make sure that the
tire size information on the ve­ hicle label is the same as the
size of the tires on the vehicle.
This is especially important 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 de­ pends on making sure that load
limits are not exceeded . Vehicle
load includes everybody and ev­
erything in and on the vehicle.
These load limits are technical­
ly referred to as the vehicle's
Gross Vehicle Weight Rating
("GVWR"). The Gross Axle
Weight Rating ("GAWR") is the
maximum load that can be ap­
plied 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 stick- er label located on the driver's
side B-pillar.
The tire pressure
label on your Audi lists the
maximum combined weight of
all of the occupants and lug­
gage or other cargo that the ve­
hicle can carry. For the location
of the tire pressure label

&_ 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 a
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 causing loss of
control and a crash.
-Always make sure that the
total load being transported

ing.
A WARNING
-Incorrect tire pressures
and/or underinflation can lead to a serious or fatal ac­
cident.
-Incorrect tire pressures
and/or underinflation cause
increased tire wear and can
affect the handling of the
vehicle.
-Incorrect tire pressures and/or underinflation can
also lead to sudden tire fail­ure, including a blowout
and sudden deflation, caus­ ing loss of vehicle control.
Checking tire pressure
The correct tire pressure for the
tires originally installed on
your vehicle is listed on the tire pressure label located on driv­
er's side 8-pillar.
The recommended tire pres­
sures are on the tire pressure
label and in the table
Tires and wheels 221
¢ page 217, 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 miles (kilometers) at low speeds during the previous
three hours. Air in the tires ex­
pands when the tire heats up as
a result of internal friction 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. There­
fore, you should never let air out of a warm tire to match
"Cold tire inflation pressure" recommendations ¢
page 217.
The tires would then be under­
inflated and could fail sudden­
ly.
The tire pressure label on your
Audi lists the recommended cold tire inflation pressures at
maximum capacity for the new,
original equipment tires that
were on your vehicle at the time it was manufactured. For the

Therefore it is essential that
the driver observe the speci­
fied tire pressure values for
the tires and the correct pressures for the function of
the tire pressure monitoring
system*.
-Always inflate tires to the
recommended and correct
tire pressure before driving
off.
-Driving with underinflated
tires bend more, letting
them get too hot resulting
in tread separation, sudden
tire failure and loss of con­
trol.
-Excessive speed and/over­ loading 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 near­
est service station to check
the tire pressure and add air
as required.
(D Note
Driving without valve stem
caps can cause damage to
the tire valves. To prevent
this, always make sure that
factory installed valve stem
caps on all wheels are secure­ ly mounted on the valve.
@ For the sake of the environment
Underinflated tires will also
increase the fuel consump­
tion.
Tires and vehicle load limits
There are limits to the amount
of load or weight that any vehi­
cle and any tire can carry. Ave­
hicle that is overloaded will not
handle well and is more diffi­
cult to stop. Overloading can not only lead to loss of vehicle
control, but can also damage .,.

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.

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.
