It beg ins with the letters "DOT"
and indicates that the tire meets
all federal standa rds. The next
two numbers or letters indicate
the plant where it was manufac ­
tured, and the last four numbers represent the week and year of
manufacture . For example,
DOT ... 221 3 ...
means that the tire was produced
in the 22nd week of 2013. The

Cold tire inflation pressure
Tire pressure affects the overall handling, performance and safety of
a vehicle.
Fig . 147 Tire pressure label: located on
driver's side 8-pillar
Tire pressure generally refers to
the amount of air in a tire that it
needs it to do its job and safely
carry the combined load of the
entire vehicle and its contents.
Tire pressure is measured in kilo­
pascals (kPa), the international
measuring unit and in pounds per
square inch (PSI). Tire pressure is
based in part on the vehicle's de­
sign and load limit -the greatest
amount of weight that the vehicle
can carry safely and the tire size.
The proper tire pressure is fre-

quently referred to as the "recom­
mended cold tire inflation pres­
sure." Air in the tires expands
when the tire heats up because of internal friction when it flexes in
use. The tire pressure is higher
when the tire has warmed up than
when it is "cold ." It is the infla-
tion pressure in a "cold" tire that
counts. Therefore , you should
never let air out of a warm tire to
match "cold tire inflation pres­
sure" recommendations. The tires ""

...
would then be underinflated a nd
could fail suddenly .
M ainta ining proper tire pressure
is one of the most important
things you can do to he lp avoid
s u dden tire fai lure . Under inflated
tires are a major cause of sudden
tire fa ilure . Keeping tires at the
r ight pressure is also important
for safe and responsive vehic le
handling, traction, braking and
load carrying.
Tire pressures are
particularly important when the
vehicle is be ing dr iven at higher
speeds, and then especially when
heavily loaded even within the
permissib le load-carrying capaci­
ties approved for your vehicle .
The recommended tire pressures
for your Audi depend on the kind of tires on your vehicle and the
number of passengers and/or
amount of luggage you will be
transport ing .
The tire pressure label is located
on the driver's side 8-pillar . The
tire pressure label lists the recom­ mended cold tire inflation pres­
s u res for the vehicle at its maxi­
mum capacity weight and tires

Tir es a nd whe els
If you wish to improve comfort
when operating the vehicle at
normal load (up to 2 occupants ),
you can adjust tire pressu res to
those specified for normal vehi­
cle load . Before operating the ve­
hicle at ma ximum load, you
must increa se the ti re pressures
to those specified for maximum
vehic le load

Bear in mind that the tire pres­
sure monitoring system can only monitor the tire pressures that
are stored. The system does not recognize the load condition of
your vehicle .

XL= reinforced or extra load tire. It may also appear as xl, EXTRA LOAD, or RF on the tire sidewall.
Because technical changes may be
made to vehicle equipment dur­
ing the model year, always com­
pare the tire size designation on
the tire pressure label on your ve­ hicle with the tires on your vehi­
cle. Make sure that the tire size information on the vehicle 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 previously owned vehicle.
Remember, your safety and that
of your passengers also depends
on making sure that load limits
are not exceeded. Vehicle load in­
cludes everybody and everything

in and on the vehicle. These load
limits are technically referred to
as the vehicle's Gross Vehicle
Weight Rating ("GVWR"). The
Gross Axle Weight Rating ("GAWR") is the maximum load
that can be applied at each of the
vehicle's two axles. The Gross Ve­ hicle Weight Rating and the Gross
Axle Weight Rating are listed on
the safety compliance sticker la­ bel located on the driver's side B­
pillar. The tire pressure label on
your Audi lists the maximum combined weight of all of the oc­
cupants and luggage or other car­
go that the vehicle can carry. For

.&_ WARNING
Overloading a vehicle can cause loss of vehicle control, a crash
or other accident, serious per­
sonal injury, and even death .
-Carrying more weight than your vehicle was designed to carry will prevent the vehicle
from handling properly and in­ crease the risk of a loss of ve ­
hicle 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 causing loss of control
and a crash.
A WARNING
-
- Incorrect tire pressures and/or
underinflation can lead to a
serious or fatal accident.
-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,
causing loss of vehicle control.
Tires and wheels
Checking tire pressure
The correct tire pressure for the
tires originally installed on your
vehicle is listed on the tire pres­
sure label located on driver 's side
8-pillar .
The recommended tire pressures
are on the tire pressure label and
in the table
c:::> page 176 , 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 m iles (kilome­
ters) at low speeds during the
previous three hours. Air in the
tires expands when the t ire heats
up as a result of internal friction
as it flexes in use . The tire pres­
sure 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 shou ld never let air out of a
warm tire to match "Cold tire in­
flation pressure" recommenda ­
tions
c:::> page 176. The tires would
then be underinflated and could
fail suddenly.
The tire pressure label on your
Audi lists the recommended cold
tire inflation pressures for the

Tires and wheels
-The use of incorrect tire pres­sure values can lead to acci­
dents or other damage. There­
fore it is essential that the driver observe the specified
tire pressure values for the
tires and the correct pressures
for the function of the tire pressure monitoring system.
-Always inflate tires to the rec­ ommended 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 control.
-Excessive speed and/overload­
ing 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
station to check the tire pres­
sure 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 instal­
led valve stem caps on all
wheels are securely mounted on the valve.
@ For the sake of the environment
Underinflated tires will also in­
crease the fuel consumption.
Tires and vehicle load limits
There are limits to the amount of
load or weight that any vehicle
and any tire can carry. A vehicle
that is overloaded will not handle
well and is more difficult to stop. Overloading can not only lead to
loss of vehicle control, but can al­
so damage important parts of the
vehicle and can lead to sudden
tire failure, including a blowout and sudden deflation that can
cause the vehicle to crash.
Your safety and that of your pas­
sengers also depends on making
sure that load limits are not ex­
ceeded. Vehicle load includes ev­
erybody and everything in and on
the vehicle. These load limits are ...

technically referred to as the vehi­
cle's
Gross Vehicle We ight Rating
("GVWR") .
The "GVWR" includes the weight
of the basic vehicle, all factory in­
stalled accessories, a full tank of
fuel, oil, coolant and other fluids 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.
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 compli­
ance sticker label located on the
driver's side B-pillar. Your Audi
has 2 seating positions . Each
seating position has a safety belt
¢ page 95, Safety belts.
The fact that there is an upper
limit to your vehicle's Gross Vehi ­
cle Weight Rating means that the
total weight of whatever is being
Tires and wheels
carried in the vehicle is limited.
The more passengers in the vehi­
cle or passengers who are heavier
than the standard weights as­
sumed mean that less weight can
be carried as luggage.
The tire pressure label on your
Audi also lists the maximum com ­
bined weight of all of the occu­
pants and luggage or other cargo
that the vehicle can carry. For the location of the label¢
page 176,
fig. 147.
