or replac ing w heels yo u have to adjust the t ire press ures on all
w heels. In addi tion, you must th en ini tia lize the ne w tire press ures in
the t ire pressure monito ring system *~
page 264 .
& 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{__, 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 pressure s 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 .
Safety first
& WARNING (cont inued )
• Only when all tires on the vehicle are filled to the correct pres­
sure, the tire pressure monitoring system* can work correctly.
• The use of incorrect tire pressure values can lead to accidents or
other damage . Therefore it is essential that the driver observe the
specified tire pressure values for the tires and the correct pres­
sures for the function of the tire pressure monitoring system*.
• Always inflate tires to the recommended and correct tire pres­
sure 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/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 station
to check the tire pressure and add air as required .
0 Note
Driving witho ut valve stem caps can cause damage to the tire valves.
T o preven t this, always ma ke sure that fa ctor y in sta lled val ve s te m
caps on all wheels a re secure ly mounted on the va lve.

Tires and vehicle Load Limits
T he re are limits to the amo unt of load or weight that a ny vehicle and
any tire c an car ry. A veh icle t hat is ove rload ed w ill not handle well and ..,_
Vehicle care Technical data

_L_T.:...:..: i r~ e:.: s~ a:::. n:..:..:: d:.....: w..:...:. h::e:.: e::.:: ls::::._ ______________________________________________ _
is more difficult 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 failure, including a blowout and sudden
deflation that can cause the vehicle to crash.
Your safety and that of your passengers also depends o n making sure
that load limits are not exceeded. Vehicle load includes everybody
and everything in and on the vehicle. These load limits are techn ically
referred to as the veh icle's
Gross Vehicle Weight Rating ("GVWR").
Th e "GVWR" includes the weight of the basic vehicle, all factory
installed accessories, a full tank of fuel, o il, coolant and other fluids
plus maximum load. The maximum load includes the number of
passenge rs that the vehicle is intended to carry ("seating capacity")
with an assumed weight of 150 lbs (68 kg) for each passenger at a
designated seating posit ion 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 must be included as part of the
vehicle load.
T he Gross Axle Weight Rating ("GAWR") is the maximum load that
can be applied at each of the vehicle's two ax les.
The Gross Vehicle We ight Rating and the Gross Axle Weight Rat ing
are listed on the safety compliance sticker label located e ithe r on the
dr iver's s ide B-pillar or on the inside of the fuel filler flap. Your Audi
has 5 seating positions, 2 in the front and 3 in t he rear for total
seating capacity of 5. Each seating position has a safety belt
=> page 135, "Safety belts".
The fact that there is an upper limit to your veh icle's Gross Veh icle
Weight Rating means that the total weight of whatever is being
carried in the veh icle (in cluding the weight of a trailer hitch and the
tongue weight of the loaded trailer) is limited . The more passengers
in the vehicle or passengers who are heavier than the standard
we ights assumed mean that less we ight can be carr ied as luggage.
Th e tire pressure label on your A udi also lists the maximum combined
we ight of all of the occupants and luggage or other cargo that the
vehicle can carry. For the location of the labe l=>
page 249, fig. 171.
& WARNING
Overloading a vehicle can cause loss of vehicle control, a crash or
other accident, serious personal injury, and even death.
• Carrying more weight than your vehicle was designed to carry
will prevent the vehicle from handling properly and increase the
risk of the loss of vehicle 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 suddenly,
including a blowout and sudden deflation, causing loss of control
and a crash.
• Always make sure that the total load being transported -
including the weight of a trailer hitch and the tongue weight of a
loaded trailer -does not make the vehicle heavier than the
vehicle's Gross Vehicle Weight Rating .•
Determining correct load limit
Use the example below to calculate the
total weight of the passengers and luggage
or other things that you plan to transport so
that you can make sure that your vehicle
will not be overloaded. ._

The tires and rims are essential parts of the vehicle's design. The tires
and r ims approved by Audi are spec ially matched to the characteris­
tics of the vehicle and can make a major contribution to good road
holding and safe handling when in good condition and properly
inflated =>& .
We recommend that all work on tires and wheels be performed by an
authorized Audi dealer. They are familiar with recommended proce­
dures and have the necessary special tools and spare parts as well as
the proper facilit ies for disposing of the old tires.
Authorized Audi dea lers have the necessary information about tech­
nical requirements for installing or chang in g ti res and rims.
Replacing tires and wheels
Tires should be replaced at least in pairs and not ind ividually (for
example both front tires or both rear t ires together).
Be sure to read and heed the tir e pressure monitoring system*
information=>
page 264.
Always buy replacement radial tires that have the same specifications
as the tires approved for your veh icle by Audi . Replacement tires must
always have the same load rating specification as the original equip­
ment or approved opt iona l tires listed in the table=>
page 249.
Audi-approved spec ification tires are specially matched to your
vehicle and its load limits, and can contribute to the important road­
holding, driv ing characteristics, and safety of the vehicle. The table (=>
page
249) lists specifications of the tires approved for the Aud i
models covered by your Owner's Literature.
The tire pressure label located either on driver's side B-p illar or inside
the fuel filler flap(=>
page 249, fig. 172) lists the specifications of
the original equipment tires installed on your ve hicle at the time it
was manufactured.
Federal law requires tire manufact urers to place standardized infor­
mation on the sidewall of all tires =>
page 2 5 7, fig. 17 5. This i nfor­
mation identifies and describes the fundamental characteristics, the
quality grade of the tire and also provides a t ire identification number
for safety standard certification and in case of a reca ll.
Tire specifications
Knowledge of tire specificat ions makes it easie r to choose the correct
tires. Rad ial tires have the tire specifications marked on the s idewall,
for examp le:
P225 / 45 R 17 91H XL
This contains the following informat ion:
P I ndicates the tire is for passenger cars (where applicable)
225 Nominal tire width in mm of the tire from s idewall edge to side-
wa ll edge. In gene ral, the large r the number, the wider the tire
45 Height/width ratio in pe rcent (aspect ratio)
R Tire construction: Radial
17 Rim diameter code (in inches)
91 Load rating code
H Speed rating letter code
XL (or "xl", "EXTRA LOAD" or "RF") indicates that the tire is "Rein­
forced" or an "Extra Load" tire
M+S (or "M/S") Indicates that the t ire has some mud and snow capa­
bili ty
The tires could a lso have the information of direction of rotation
=>page 245.

________________________________________________ T_ i_ re _ s_ a_ n_d_ w_ h_ e_ e_l _s _ ........
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS) that ill uminates a low tire pres­
sure telltale when one or more of your tires is signif icantly under­
inflated . Accordingly, when the low tire pressure telltale illuminates,
you should stop and check your tires as soon as possible, and inflate them to the proper pressure. Driving on a significantly under-inflated
ti re causes the tire to overheat and can lead to tire fa ilure. Unde r­
inf lation also reduces fuel efficiency and tire tread life, and may
affect the vehicle's handling and stopping ability.
Please note that the TPMS is not a substitute for proper tire mainte­
nance, and it is the driver's responsibility to maintain correct tire
pressure, even if under -inflation has not reached the level to trigger
illumination of the TPMS low tire pressure te lltale.
Your vehicle has also been equipped with a TPMS malfunction ind i­
cator to indicate when the system is not operating properly. The
TPMS malfunction indicator is combined w ith the low tire pressure
telltale . When the system detects a malfunction, the telltale will
flash for approximate ly one minute and then remain continuously
illuminated. This sequence will continue upon subsequent vehicle
start -ups as long as the malfunction exists.
When the ma lfunction indicator is illum inated, the system may not
be able to detect or signa l low tire pressure as intended. TPMS
ma lfunctions may occur for a var iety of reaso ns, includ ing the instal­
lation of replacement or alternate tires or wheels on the vehicle that
prevent the TPMS from functioning properly. Always check the TPMS
malfunction telltale after replacing one or more tires or wheels on
yo ur vehicle to ensure that the replacement or alternate tires and
wheels allow t he TPMS to continue to funct io n properly .•

Using the ABS sensors, the tire pressure monitoring system compares
the tire tread circumference and vibration characteristics of the indi­
vidual tires.
If the pressure decreases in one or more tires, this is indi-
cated in the instrument cluster with a warning symbol and a
message ~ fig. 176 . The driver message in the display goes out after
5 seconds . The driver message can be displayed again by pressing the
I CHECK) button©~ page 8, fig. 2. If on ly one tire is affected, the
display will i ndicate its pos it ion. ._
