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
vehicle equ ipment dur ing the model yea r, a l
ways compa re 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 tires 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 limits 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 We ight
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 Weight Rating are listed on the
safety compliance st icker label located on the
driver's side B-p illa r. The t ire pressure label o n
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

A WARNING
Overloading a vehicle can cause loss of ve
hicle control, a crash or other accident, se
rious personal injury, and even death.
- Carrying 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.

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
~ page 229, 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 tire inflat ion
pressure" recommendat io ns ~
page 229 . Th e
ti res wo uld then be unde rinfl ated and co uld
fail suddenly.

Most ti res lose a ir naturally over time. They
can also lose some a ir if you drive ove r a pot
ho le or hit a curb while parking . It is usua lly
not possible to see whether the radial tires
used today are under inflated just by looking
at them.
Therefore, be sure to check tire pressures at
l east once a month and always before going
on a long tr ip. Make sure to take the number
of people and the amount of luggage into ac
count when adjusting tire pressure for a trip -
even one that you would not consider to be
" long." See
c::> page 233 , Tires and vehicle
load limits
for more important information .
Always use an accurate tire pressure gauge
when checking and adjusting inflation pres
sures . Check all of the t ires and be sure not to
forget the spare t ire . If the pressure in any tire
is too high when the tire is "cold ," le t 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 l oad (passengers and luggage) and kind of
driving you plan to do .
I f the pressure in any tire is too low, note the
diffe rence between the pressure in the cold
tire and the pressure you need and add the air
that you need to reach the cor rect pressure for
the vehicle load (passengers and luggage) for
the tires on your veh icle as lis ted on the on
your veh icle and in this manual and the k ind
of dr iv ing you pla n to do .
Never e xceed th e ma ximum inflatio n pres
sure li sted on th e tire s id ewall for an y rea
son .
Remember that the vehicle manufacturer, not
the tire manufacturer, determ ines the correct
tire pressure for the t ires on your vehicle .
It is important to check the tire pressure when
the tires are cold .
- Read the req uired ti re pressure from the tire
pressure label. The tire pressure labe l is lo
cated on the driver's side B-pi llar . - Tu
rn the va lve stem cap counter -clockwise
to remove it from the tire va lve .
- Place the air pressure gauge on the va lve.
- The tire pressu res should only be checked
and adj usted when the tires are co ld. The
slightly raised pressures of warm tires must
not be reduced.
- Adjust the tire pressure to the load you are
carrying.
- Reins tall the valve stem cap on the va lve.
When should I check the tire pr essure ?
The correct tire pressure is especially impor
tant at high speeds. The pressure should
the refore be che cked at least once a mo nth
and always before sta rting a jo urney. Do not
f orget to c heck the ti re p ress ure for the spare

c::> page 247.
When should I adjust the tire pressures?
Adjust the t ire pr essure to the load you are
ca rrying. After cha ng ing a whee l
or replacing
whee ls you have to adjust the ti re p ress ures
on all whee ls. In addition, you m ust then
store the new tire pressures in the tire pres
s u re monitoring system
c::> page 243 .
A WARNING
Incorrect tire pressures and/or underinfla
tion can lead sudden tire fa ilure, loss of
control, collision, serious personal injury
or even death.
- When the warning symbol
RIJ appears in
the instrument cluster, stop and inspect
the t ires.
- Incorrect tire pressure and/or underinfla
tion can cause increased tire wear and
can affect the handling of the vehicle and
stopping abi lity.
- Inco rrect tire pressures and/or underin
f lation can a lso lead to s udden t ire fail
ure, including a blowout a nd sudden de

- The driver is responsible for the co rrect
tire pressures for all tires on the veh icle.
The appli cable pressure values are locat
ed on a sticker on the dr iver's side B-pil-

Page 235 of 288

-Only when all 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 driver
observe the specif ied tire pressure values
for the tires and the co rrect p ress ures for
the f unction of t he tire pressure mo nitor

- Excessive spee d and/ove rloading can
cause heat bui ld -up, sudden tire fa il u re
and loss of control.
- If the t ire pressure is too low or too high,
the tires w ill wea r prematurely and 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

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 .
A vehicle that is ove rloaded w ill not ha ndle
well and is more difficult to stop . Overload ing
can no t on ly lead to loss o f vehicle con tro l,
Tire s an d wheel s 233
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 Axle 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 for
total seating capacity of 5 . Each seating posi
t ion has a safety belt
~ page 131, Safety
belts.
The fact that there is an upper limit to your
vehicle's Gross Vehicle Weight Rating means
t h at the total weight of whatever is bei ng car
ried in the vehicle ( in cl ud ing t he weight of a
t ra ile r hi tc h a nd the tongue we ight of t he
l o ad ed tr ailer) is lim ited. The more p assen
gers in the vehicle or passengers who are
heavier than the standard weights assumed
mean that less weight can be carried as lug -
gage.

Determining correct load limit
Use the example below to cal
culate the total weight of the
passengers and luggage or oth
er things that you plan to trans
port 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 QC- CU PANTS AND CARGO
SHOULD NEVER EXCEED XXX
KG OR XXX LBS" on your ve
hicle's placard (tire inflation
pressure label)
¢ page 229,
fig. 156.
2. Determine the combined weight of the driver and pas
sengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and pas
sengers from
"XXX" kilo
grams or
"XXX" pounds
shown on the sticker
¢ page 229, fig. 156.
4. The 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 available
cargo and luggage load ca pacity is 650 lbs. (1400-7 50
(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
Page 237 of 288

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.
~check the tire sidewall
(¢page 236, fig. 160) to de
termine the designated load
rating for a specific tire.
Tire service life
The service life of tires depends on a lot of
different things including proper installation
and balan cing, correct tire pressure and driv
ing style.

r:::>fig. 158 run ning across the tread. Depend
ing on the make, there will be six to eight of
them evenly placed around the tire. Marks on
the tire sidewall (for examp le "TWI" or other
symbols) indicate the positions of the tread
wear indicators . Worn tires must be replaced .
D ifferent figures may apply in other countr ies
¢ Lr:,. .
Tire pressure
Incorrect t ire pressure causes premature wear
and can cause sudde n tire blow-out. For this
reason, tire pressure must be checked at least
once a month
r::> page 231.
Driving style
Driving fast around curves , heavy acce lerat ion
and hard braking increase tire wear .
Rotating tires for more even wear
For all four tires on your vehicle to have the
same service life, we recommend that the
front and rear tires are rotated according to
the tire manufacturer's suggested tire rota
tion intervals. Please remember the follow
i ng:
- Tire rotation intervals may differ from the
veh icle service intervals outlined in your
Warranty
& Maintenance booklet.
- The longer one tire is used in one location
on the vehicle, the more it wears at certain
points; therefore, we recommend that you
follow the tire manufact urer's suggested
tire rotation intervals.
- Ve hicl es w ith front -wheel dr ive experience
more tread wear on the fro nt wheels com
pared to a ll-wheel drive (quattro) .
- Please rotate tires as shown
r:::> fig . 159 .
-Extra care must be taken when rotating di-
rection-specific tires
r::> page 253 .
Wheel balancing
The wheels on new vehicles are balanced .
However, various s ituations during everyday
driv ing can cause them to become
Page 238 of 288

236 Tires and wheels
unbalanced, resulting in vibrations you can
usually feel through the steering whee l.
Unbalanced wheels must be rebalanced to
avoid excessive wea r on steer ing, suspension
and tires . A wheel must a lso be rebalanced
when a new tire is installed.
Incorrect wheel alignment
I ncorrect wheel alignment can cause exces
sive tire wear, impair ing the safety of the veh i
cle. If tires show excess ive wear, have the
wheel alignment checked by an authorized
Audi dealer or qualified workshop.
All-wheel drive
Vehicles w ith quattro must a lways have tires
of the same size, construction and tread type.
F or details see
<=> page 190 .
A WARNING
Sudden tire failure can lead to loss of con
trol, a crash and ser ious persona l injury!
- Never drive a vehicle when the tread on
any tire is worn down to the wear indica
tors.
- Worn tires are a safety hazard, they do
not grip well on wet roads and increase
your risk of "hydroplaning" and loss of
control.
- Always keep chemicals that can cause
tire damage, such as grease, oil, gasoline
and brake fluid away from t ires.
- Tires age even if they are not being used
and can fail suddenly, especially at high
speeds. Tires that are more than 6 years
old can only be used in an emergency
and then with special care and at lower
speeds.
- Never mount used tires on your vehicle if
you are not sure of their "previous histo
ry." Old used tires may have been dam
aged even though the damage cannot be
seen that can lead to sudden tire failure
and loss o f vehicle control.
