The correct tire pressure for the spare wheel is
located on a label on the driver's side B-pillar.
Because technical changes may be made to
vehicle equipment during the model year, a l­
ways compare the tire size designation on the
tire pressure label on your vehicle with the
tires on your vehicle. Make sure that the tire
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
l ongs to someone else or you bought the veh i­
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 su re that
l oad limits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
vehicle . These load limits are technically refer- red to as the veh
icle's Gross Vehicle Weight
Rat ing ("GVWR"). The Gross Axle Weight Rat­
ing ("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 compl iance sticke r label located on the
driver's side B-pillar. The tire pressu re labe l on
your Audi 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 tire pressure label

A WARNING
Overloading a vehicle can cause loss of ve­
hicle contro l, a crash or other accident, se­
rious personal injury, and even death.
- Carrying more we ight than your veh icle
was designed to carry will prevent the

vehicle from handling properly and in­crease the risk of a loss of veh icle con­
tro l.
- 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 causing loss of con­
tro l and a crash .
- Always make sure that the tota l load be­
ing transported -including the we ight of
a tra ile r hitch and the tongue weight of a
loaded trailer -does not make the veh i­
cle heav ier than the veh icle's Gross Vehi­
cle Weight Rating.
A WARNING
- Incorrect tire pressures and/or underin­
flation can lead to a serious o r fatal acci­
dent.
- Incorrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle .
- Incorrect tire pressures and/or underin­
flation can also lead to sudden tire fa il­
ure, including a blowo ut and sudden de­
flation, causing loss of vehicle control.
Checking tire pressure
.
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressure Lobel located on driver's side 8-pil­
lor.
The recommended tire pressures are on the
tire pressure labe l and in the tab le
c:> page 239, Cold tire inflation pressure .Th is
means that the pressure must be checked and
adjusted when the tire has not been driven for
more than a couple of m iles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up
as a result of inte rna l fr iction as it flexes in
use. The ti re p ress ure is higher when the tire
h as warmed up than when it is "cold."
It is the inflat ion pressure in a "cold " tire that
counts. Therefo re, you shou ld neve r let air out
Tire s an d wheel s 241
of a wa rm tire to match "Cold tire inflat ion
pressure" recommendations
c:> page 239. T he
tires wou ld then be underinflated and cou ld
fail suddenly .
T he t ire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
maximum capacity for the new, orig inal
equipment tires that were on your vehicle at
the time it was manufactured. For the loca­
tion of the labe l
c:>poge 239, fig . 183 .
Most tires lose air natura lly over t ime. They
can a lso lose some air if you drive over a pot­
hole or hit a curb while park ing. It is usually
not possible to see whether the rad ia l tires
used today are underinflated just by looking
at them.
Therefore, be sure to check t ire pressures at
least once a mo nth and a lways before going
o n a long tr ip . Make sure to take the number
of peop le and the amount of luggag e into ac­
count when adjust ing tire p ressu re for a trip -
even one th at yo u wo uld not conside r to be
"long." See¢
page 243, Tires and vehicle
load limits
for mo re important information .
Always use an accura te ti re pressu re gauge
whe n checking and adj usting i nflation pres­
s ur es . Check a ll of the tires and be sure not to
forget the spare tire.
If the pressure in any tire
is too high when the ti re is "cold," let air o ut
of the t ire s low ly w ith the edge of the tire
gauge and keep checking the pressure until
you reach the pressure that is correct for the load (passengers and luggage) and k ind of
driv ing you plan to do .
If the pressure in any tire is too low, note the
difference be tween the pressure in the cold
ti re and the pressure you need and add the air
that you need to reach the correct pressure for
the ve hicle load (passengers and luggage) for
t h e tires on you r veh icle as l isted on the on
you r vehicle and in this ma nual a nd the k ind
of driving you plan to do.
Nev er e xceed the ma ximum inflation pre s­
s ure lis te d on the tir e sidewall for any re a­
son.

Underinflated tires will a lso increase the

Tires and vehicle load limits
There are limits to the amount of load or
weight that any vehicle and any t ire can carry.
A vehicle that is overloaded w ill not handle
well and is more difficult to stop. Overload ing
can not only lead to loss of vehicle control, but can a lso damage importan t pa rts of the
ve hicle and can lead to s udden tire failure, in­
cluding a blowout and sudden deflation that
can cause the veh icle to crash.
Your safety and that of yo ur passenge rs a lso
depends on making s ure that load limits are
not exceeded. Vehicle load includes everybody
and everything in and on the vehicle. These
load limits are technica lly referred to as the
vehicle's
Gros s Vehicle We ight R ating
("GVWR").
The "GVWR" includes the weight of the basic
vehicle, all factory insta lled accessories, a full
tank of fue l, oil, coolant and other fluids plus
maximum load. The maximum load includes
the number of passengers that the vehicle is intended to carry ("seating capacity") with an
assumed weight of 150 lbs (68 kg) for each
passenger at a des ignated seat ing pos ition
and the total we ight of any l uggage in the ve­
hi cle. If you tow a trailer, the weight of the
trailer hitch and the tongue weight of the loaded trailer must be included as part of the
vehicle load.
The
Gro ss Axl e W eight R ating ("GAWR") is
the maximum load that can be app lied at each
of the vehicle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle Weight Rating a re listed on the
safety compliance sticker labe l located on the
driver's side B -pillar . Your Audi has 5 seating
positions, 2 in the front and 3 in the rear for
total seating capacity of 5. Vehicles with pow­
er individual rear seats* have 4 seating posi­
tions, 2 in the front and 2 in the rear for total
Tire s an d wheel s 243
seating capacity o f 4 . Each seating position
has a safety belt~ page 134, Safety belts .
T he fact th at there is a n upper limit to yo ur
vehicle's G ross Vehicle Weight Rating means
that the total weight of whatever is being car­
ried in the vehicle (including the weight of a
tra iler hitch and the tongue weight of the
l oaded tra iler) is lim ited. The more passen­
gers in the vehicle or passengers who are
heavier than the standard we ights assumed
mea n that less we ight can be carried as lug­
gage .
The tire pressure label on your Audi also lists
the maximum combined weight of all of the
occupants and luggage or other cargo that
the vehicle can carry . For the locat ion of the
label ~page239, fig.183.
A WARNING
Overloading a vehicle can cause loss of ve­
hicle contro l, a crash or other accident, se­
rious personal injury, and even death.
- Ca rrying more we igh t than your veh icle
was des igned to carry wi ll prevent the
vehicle from handling properly and in ­
crease the risk of the 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 suddenly, incl uding a blowout
and sudden deflation, causing loss of
control and a crash .
- Always make sure that the total load be­
ing transported -includ ing the weight of
a trailer hitch and the tongue we ight of a
loaded trailer -does not make t he vehi­
cle heavier than the vehicle's Gross Vehi­
cle Weight Rating.

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 OC­
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS" on your ve ­
hicle's placard (tire inflation
pressure label)¢
page 239,
fig. 183 .
2. Determ ine the combined
weight of the driver and pas ­
sengers that will be riding in
your vehicle.
3 . Subtract the combined
weight of the dr iver and pas­
sengers from
"XXX" kilo­
grams or
"XXX" pounds
shown on the sticker
¢ page 239, fig. 183.
4 . T he 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 ava ilable
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 .

Vehicle capacit y weight
The vehicle capac ity we ight (max. load) is list­
ed either on the dr iver's side B-pillar or inside
the fuel filler flap.
Roof weight
The max imum perm issible roof weight is 220
lb (100 kg ).
The roof weight is made up of
the we ight of the roof rack system and the
weight of the object be ing transported

.&, WARNING
- T he ac tual Gross Axle Weight Rat ing at
the front and rear axles shou ld not ex­
ceed the permiss ible weights, and their
combination must not exceed the Gross
Vehicle Weight Rat ing .
- Exceeding permissib le weight ratings can
result in vehicle damage, accidents and
personal injury.
CD Note
- The vehicle capacity weight figures apply
when the load is distributed evenly in the
vehicle (passengers and luggage). When
transporting a heavy load in the luggage
compartment, carry the load as near to
the rear axle as possib le so that the veh i­
cle's handling is not impa ired.
- Do not exceed the maximum permissible
axle loads or the maximum gross vehicle
weight. Always remember that the vehi­
cle's handling will be affected by the ex­
tra load. Therefore, adjust you r speed ac ­
cord ingly.
- Always observe loca l regu lations.
