possible to see whether the radial tires used today are underinflated
just by looking at them.
Therefore, be sure to check tire pressures at least once a month and
always before going on a long trip. Make sure to take the number of
people and the amount of luggage into account when adjusting tire
pressure for a trip -even one that you would not consider to be
"long." See=>
page 321, "Tires and vehicle load limits" for more
important information.
Always use an accurate tire pressure gauge when checking and
adjusting inflation pressures . Check all of the tires and be sure not
to forget the spare tire. If the pressure in any tire is too high when
the tire is "cold," let air out of the tire slowly with 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 kind of
driving you plan to do.
If the pressure in any tire is too low, note the difference between the
pressure in the cold tire and the pressure you need and add the air
that you need to reach the correct pressure for the vehicle load
(passengers and luggage) for the tires on your vehicle as listed on
the on your vehicle and in this manual and the kind of driving you
plan to do.
Never exceed the maximum inflation pressure listed on the tire
sidewall for any reason.
Remember that the vehicle manufacturer, not the tire manufacturer,
determines the correct tire pressure for the tires on your vehicle.
It is important to check the tire pressure when the tires are cold.
• Read the required tire pressure from the tire pressure label. On
USA vehicles, the tire pressure label is located on the driver's side
8-pillar . On Canada vehicles, the tire pressure label is located either
on the driver's side 8-pillar or inside the fuel filler flap.
• Turn the valve stem cap counter-clockwise to remove it from the
tire valve.
• Place the air pressure gauge on the valve. • The
tire pressures should only be checked and adjusted when
the tires are cold. The slightly raised pressures of warm tires must
not be reduced .
• Adjust the tire pressure to the load you are carrying.
• Reinstall the valve stem cap on the valve.
When should I check the tire pressure?
The correct tire pressure is especially important at high speeds. The
pressure should therefore be checked at least once a month and
always before starting a journey. Do not forget to check the tire pres­
sure for the spare wheel =>
page 337.
When should I adjust the tire pressures?
Adjust the tire pressure to the load you are carrying. After changing
a wheel
or replacing wheels you have to adjust the tire pressures on
all wheels. In addition, you must then initialize the new tire pres­
sures in the tire pressure monitoring system=>
page 42.
& WARNING
Incorrect tire pressures and/or underinflation can lead sudden tire
failure, loss of control, collision, serious personal injury or even
death.
• When the warning symbol I appears in the instrument
cluster, stop and inspect the tires.
• Incorrect tire pressure and/or underinflation can cause
increased tire wear and can affect the handling of the vehicle and
stopping ability .
• Incorrect tire pressures and/or underinflation can also lead to
sudden tire failure, including a blowout and sudden deflation,
causing loss of vehicle control.
• The driver is responsible for the correct tire pressures for all
tires on the vehicle. The applicable pressure values are located on a sticker on the driver's side 8-pillar or on the inside of the fuel
filler flap. .,_

& 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 .
Your sa fety and that o f your passe ngers also depe nds on mak ing
sure that load limits are not exceeded . Vehicle load includes every ­
b ody and everyth ing in and on t he veh ic le . T hese load lim its a re
technica lly referred to as the vehicle's
Gross Vehi cle We ight Rating
(" GVWR"l .
The "GVWR" includes the weight of the basic veh ic le, all factory
insta lled accesso rie s, a ful l tank of fuel , oil, coolant an d other fluids
p lus max imum load. T he ma xim um load inc ludes the number o f
passe ngers that the veh icle is intended to carry ("seat ing capacity")
w ith a n assu med we ight of 150 l bs (68 kg) fo r each passen ger at a
designated seating position and the total weight of any luggage in
the v ehicle. I f you tow a trailer, the we ig ht o f the tra ile r hi tch and t he
tongue weight of the loaded trailer must be includ ed as part of the
ve hicle l oad.
The
Gross Axle Weight Rating ("GAWR"l is t he maximum load that
can be applied at each of the vehicle's two ax le s.
The Gross Ve hicle We ig ht Rat ing and t he G ross A xle Weig ht Rat ing
are listed on the safety comp liance stic ker label located either on
t he d rive r's side 8 -p illar or on th e inside of the fuel fil ler fla p. You r
Audi has 5 seating positions, 2 in the front and 3 in the rear for total
seating ca paci ty of 5 . Each seating p ositi on has a safe ty be lt

holding, driving characteristics, and safety of the vehicle. The table
(~ page 37 7) lists specifications of the tires approved for the Audi
models covered by your Owner's Literature .
The tire pressure label located either on driver 's side 8 -pillar or
inside the fuel fi ller flap (~
page 317, fig. 241) lists the specifica ­
tions of the original equipment tires installed on your vehicle at the
time it was manufactured.
Federal law requires tire manufacturers to place standardi zed infor ­
mation on the sidewa ll of al l tires ~
page 325, fig. 244 . T his informa ­
tion identifies and describes the fundamenta l characteristics, the
quality grade of the tire and also provides a tire identification
number for safety standard certification and in case of a recall.
T ire spe cifi catio ns
Knowledge of tire specifications makes it easier to choose the
correct tires . Radial tires have the tire specifications ma rked on the
sidewall, for example :
P245 / 45 R 17 99 H XL
This contains the fo llowing information :
P Ind icates the tire is for passenger cars (where app licable)
24 5 Nominal tire width in mm of the tire from sidewall edge to side -
wall edge. In general , the larger the number , the wider the tire
45 Height/width ratio in percent (aspect ratio)
R Tire construction: Radial
17 Rim diameter code ( in inches)
99 L oad rating code
H Speed rat ing letter code
XL (or "xi ", "EXTRA LOAD", or "RF") indica tes that the tire is a"Rein­
forced" or an "Extra Load" tire
M +S (or "M/S") Indicates that the tire has some mud and snow capa ­
bili ty
The tires could also have the information of direction of rota tion
~ page 313.
Ti re manuf acturing d ate
T he manufacturing date is a lso indicated on the t ire sidewa ll
(possibly on ly on the
inner side of the wheel!:
"DO T ... 2207 ... " means, for example, that the tire was produc ed in
the 22th week of 2007.
S peed rating (lett er cod e)
The speed rating letter code on the whee ls indicates the maximum
permissible road speeds~
