p ill ar
Tire pressure genera lly refers to the amo unt
of air in a tire that it needs it to do its job and
safely car ry the combined load of the en tire
vehicle and its contents . T ire pressure is
measured in kilopasca ls (kPa) , the interna ­
tional measu ring unit and in pounds per
s quare inch (PSI). Tire p ressure is based in
part on the vehicle's design and load limit -
the greatest amount of weight that the vehi ­
cle can carry safe ly and the t ire size . The prop­
e r tire pressu re is frequent ly referred to as the
" recommended cold tire inf lation pressure ."
Air in the tires expands when the ti re heats up
bec ause of interna l fri ct ion when it flexes in
use. The tire p ress ure is higher when the tire
has warmed up than when it is "cold ." It is the
inflat ion p ressure in a "cold" tire that counts.
Therefore, you should never let air out of a
warm tire to match "cold tire inflation p res­
sure" recommendations. The t ires would the n
be underi nflated and could fail suddenly .
Maintaining proper tire pre ssure is one of the
most important things you can do to he lp
avoid sudde n tire failure . Underinflated t ires
are a majo r cause of sudden tire failure . Keep­
i ng tires at the r ight pressure is also impor-

tant for safe and respo nsive ve hicle han dling,
tr action, braking and load carrying.
Tir e pres­
sure s are particul arly important when the
vehicle i s being dr iven at higher speeds, and
then e speciall y when hea vily loaded even
within the pe rmissible load- carrying capaci­
ties app roved for your veh icle .
The recommended t ire pressures for your Audi
depen d on the kind of tires on your vehicle
and the n umber of passengers and/or amount
of luggage you wi ll be transporting.
The tire pressure label is located on the driv­
er 's side B-pillar. The tire pressure labe l lists
the recommended cold t ire inflat ion pressures
for the vehicle at its maximum capac ity
weight and tires that were on your veh icle at
the time it was manufactured .
If you wish to improve comfort when operat­
ing the vehicle at normal lo ad (up to 2* /3
occup ants ), you can adjust t ire pressures to
those specified for normal v ehicle load . Be­
fore operating the vehicle at maximum load ,
you must increase the tire pre ssures to tho se
spe cified for maximum v ehicl e load

254 Tires and wheels
Bear in mind that the tire pressure monitoring
system* can only monitor the tire pressures
you have stored . The system does not recog­
nize the load condit ion of your vehicle.
The effectiveness of the tire pressure monitor ­
ing system* will be impaired if you store nor­
mal load pressures but then operate the vehi ­
cle at its max imum load

See the illustration c:> fig. 204 for the location
of the label on driver's side B-pillar (color of
the act ua l label and exact location on the ve­
hicle will vary slightly). Note
that the following table is accurate at
the time of going to press and is subject to
change. In the event of d iscrepancies, the t ire
pressure label is located on the driver's side B­
pillar always takes precedence.
The table below lists the recommended cold

The correct tire pressure for the spare wheel is
l ocated on a label on the driver's side B-pillar.
Because tec hnical changes may be made to
veh icle equ ipment dur ing the model yea r, a l­
ways compare the tire size designation on the
tire pressure label on your vehicle wit h the
tires on your vehicle . Make s ure that the tire
size information on the veh icle label is the
same as the s ize of the t ires on the vehicle.
This is especially important if the vehicle be ­
longs to someone else or you bought the veh i­
cle with different rims/tires or you boug ht the
ve hicle as a previously owned vehicle.
Remember, your safety and that of your pas­
sengers also depends on mak ing su re that
l oad l imits are not exceeded. Vehicle load in­
cludes everybody and everything in and on the
veh icle. These load limits are technically refer­
red to as the vehicle's Gross Vehicle Weight
Rating ("GVWR") . The Gross Ax le Weight Rat ­
ing ("GAWR") is the maximum load that can
be app lied at each of the veh icle's two axles.
The Gross Vehicle Weight Rating and the
Gross Axle We ight Rating are listed on the
safety compliance st icker label located on the
driver's side B-p illar . The t ire pressure label on
your Aud i lists the maximum combined
weight of a ll of the occupants and luggage or
other cargo that the vehicle can carry. For the
l ocat ion of the tire pressure labe l

A WARNING
Overloading a vehicle can cause loss of ve­
hicle control, a crash or other accident, se­
rious personal injury, and even death.
- Car rying more weight than yo ur vehicle
was designed to carry will prevent the
vehicle from handling properly and in­
crease the risk of a loss of veh icle con­
trol.
- 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
t rol and a crash.

-Always make sure that the total load be­
ing transported - includ ing the weight of

cle Weight Rating.
A WARNING
- Inco rrect tire pressures and/or underin­
flation can lead to a ser ious or fatal acci­
dent.
- Inco rrect tire pressures and/or underin­
flation cause increased tire wear and can
affect the handling of the vehicle.
- Inco rrect tire pressures and/or underin­
flation can a lso lead to sudden t ire fail­
ure, including a blowou t and sudden de­
flation, caus ing loss of veh icle contro l.
Checking tire pressure
The correct tire pressure for the tires original­
ly installed on your vehicle is listed on the tire
pressvre label located on driver's side 8-pil ­
lar.
T he recommended tire pressures are on the
ti re pressure label and in the table
c;, page 253, Cold tire inflation pressure .This
means that the pressure m ust be checked and
adjusted when the tire has not been dr iven for
more than a couple of miles (kilometers) at
low speeds during the previous three hours.
Air in the tires expands when the tire heats up
as a result of internal frict ion as it flexes in
use. The tire pressure is h igher when the tire
has warmed up t han when it is "cold."
It is the inflation pressure in a "cold" t ire that
counts. Therefore, you should never let a ir out
of a warm tire to match "Cold t ire inflat ion
pressure" recommendat io ns
c;, page 253 . The
ti res wo uld then be unde rinfl ated and co uld
fail suddenly.
T he tire pressure label on your Audi lists the
recommended co ld tire inflation pressures at
max imum capacity for the new, or ig inal
equipment tires that were on your vehi cle at

-Only when a ll tires on the vehicle are fi l­
led to the correct pressure, the tire pres­
sure monitoring* system can work cor­ rect ly.
- The use of incorrect tire pressure values
can lead to accidents or other damage.
Therefore it is essential that the d river
observe the specif ied tire pressure values
for the tires and the co rrect p ress ures for
the f un ct ion of t he tire pressure mo nitor­
ing sy stem*.
- Always inflate ti res to the recommended
and co rrec t tire pressu re befo re dr ivi ng
off.
- Driv ing wi th under infla ted ti res bend
more, letti ng them get too ho t res ulting
in t read separation, sudden t ire fail ure
and loss of control.
- Excessive spee d and/ove rloading can
ca use heat bui ld -up, sudden tire fa il ur e
and loss of control.
- If the t ire pressure is too low or too high,
the tires w ill wea r prematu rely an d the
vehicle will not hand le we ll.
-If the t ire is no t flat and you do no t have
to change a w heel imme diate ly, drive at
reduced speed to the nearest service sta­
t ion to check the tire pressure and add
air as required.
(D Note
Driving without va lve stem caps ca n cause
damage to the t ire va lves. To prevent this,
always make s ure that facto ry installed
valve stem caps on all wheels a re secure ly
mounted on the va lve .
@) For the sake of the environment
Underinflated tires will a lso increase the
fue l consumption .
Tires and vehicle load limits
There are limits to the amount of load or
weight that any veh icle and any t ire can carry .

but can also damage important parts of the
vehicle and ca n lead to sud den tire fai lure, in ­
clud ing a b lowout and s udden def lation that
can cause the vehicle to cras h.
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 veh icle. These
load lim its are technically referred to as the
vehicle's
Gross Vehicle We ight Rating
("GVWR ") .
The "GVWR" includes the weight of the basic
vehicle, all factory installed accessories, a full
tank of fuel, o il, coo lant and other fluids plus
maximum load . The max imum load includes
the number of passenge rs that th e vehicle is
i n tended to car ry ("seat ing capa city") wi th an
ass umed we igh t of 150 lbs (68 kg) fo r each
passenger at a designated seating posi tion
and t he tota l weight of any luggage i n the ve­
hicle . If you tow a trai ler, the weight of the
tra iler hitch and the tongue weight of the
loaded tra iler must be included as part of the
vehicle load.
T he
Gro ss Axle Weight Rating ("GAWR") is
the maximum load that can be applied at each
of the vehicle's two axles.
T he Gross Vehicle Weight Rating and the
G ross Ax le Weig ht Rating are listed on the
safety comp liance sticker label located on the
driver's side B-pillar. Your Audi has 5 seat ing
pos itions, 2 in the front and 3 in the rea r fo r
total seating capacity of 5 . Vehicles with pow­
er ind iv idual rea r seats* have 4 seat ing pos i­
tions, 2 in the front and 2 in the rea r fo r total
seat ing capac ity o f 4. Each seating position
has a safety belt~
page 144, Safety belts.
The fact that there is a n uppe r limit to you r
vehicle's G ross Vehicle We ight Rating means

.&, 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.
(D 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.
