forget the spare tire. If the p ress ure in any tire
is too high when the tire is "cold", let air out
of the tire slowly with the edge of the t ire
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
d ifference between the pressure in the cold
tire and the pressure you need and add the a ir
that you need to reach the correct pressure for
the veh icle load (passengers and luggage) for
the tires on your veh icle as listed on the on
your ve hicle and in this manua l and the kind
of dr iving you p lan to do .
Never exce ed the ma ximum inflation pres

Remember that the vehicle manufacturer , not
the t ire manufacturer , determ ines the co rrect
tire pressure for the tires on your veh icle .
It is important to check the tire pressure when
the t ires a re cold .
- Read the req uired tire press ure from the tire
pressure label. The tire pressure labe l is lo

When should I check the tire pressure?
T he co rrect tire pressu re is especially impor
tant at h igh speeds. The pressure should
therefore be checked at least once a month
and always before sta rting a jo urney . Do not
forget to check the tire pressure for the spare
whee l.
When should I adjust the tire pres sures?
Adjust the t ire pressure to the load you a re
carrying . After changing a whee l
or replacing
whee ls yo u have to adjust the tire pressu res
on all whee ls. In addition, yo u m ust then initi
alize the new tire pressures i n the t ire pres
sure monitoring system*

Tires and vehicle load limits
There are limits to the amo unt 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. Overloading
can not only lead to loss of vehicle contro l,
but c an also damage import ant parts of the
vehicle and can lead to sudde n tire failure, in
cluding a blowout and sudden deflation that
can cause t he veh icle to crash .
Your safety and that of your passengers a lso
depends on making sure that load limits are
not exceeded . Vehicle load includes everybody
and everyth ing in and on the vehicle. These load lim
its are technically referred to as the
vehicle's
Gro ss Vehicle Weight R ating
("GVWR").
T he "GVWR" includes t he weight of the basic
vehicle , a ll f actory installed accessories, a f ull
tank of fuel, oi l, coo lant and other f luids plus
maximum load. The max imum load incl udes
the number of passengers that the vehicle is
intended to carry ("seat ing capac ity ") wi th an
assumed we ight of 150 lbs . (68 kg) for each
passenger at a designated seating posit ion
and the total weight of a ny luggage in the ve
hicle. If you tow a trai le r, the we ight of the
t ra ile r hi tc h and the tongue we ight of the
l oaded tra iler mus t be include d as part of the
vehicle load .
T he
Gro ss Ax le Weight Rating ("GAWR ") is
the max imum load that can be applied a t each
of the veh icle's two axles .
T he Gross Vehicle Weight Rat ing and the
G ross Ax le Weig ht Ra ting are listed on the
sa fety comp lian ce s ticke r label loca ted on the
driver's side B-pillar. Yo ur Audi has 4 seat ing
pos itions , 2 in the front and 2 in the rea r fo r
total seati ng capacity of 4. Each seating posi
t ion has a seat belt c:>
page 132, Safety belts.
T he fact that there is an upper limit to yo ur
vehicle's Gross Vehicle Weight Rating means
t h at the total weight of whatever is being car
ried in the vehicle ( includ ing the weight of a
trailer hitch and the tongue weight of the
loaded tra iler) is lim ited. The more passen
gers in the vehicle or passengers who are
heavier tha n the sta ndard we igh ts assumed
mean that less we ight can be carried as lug
gage.
The tire pressure label o n your Aud i also lists
the max imum combi ned weig ht of all of the
occupants and luggage or other cargo that
t h e vehi cle can carry . Fo r th e lo ca tion of the

8_ WARNING
<=
Over loading a vehicle can cause loss o f ve -
hicl e co ntro l, a c rash or other accident, se-
rious personal injury, and even death. .,.
-Carrying more weight than your vehicle
was designed to carry will 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
vehicle within a safe distance.
- Tires on a vehicle that has been overload
ed can fail suddenly, including a blowout
and sudden deflation, causing loss of
control and a crash.
- Always make sure that the total load be
ing transported -including the weight of
a trailer hitch and the tongue weight of a
loaded trailer - does not make the vehi
cle heavier than the vehicle's Gross Vehi
cle Weight Rating.
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 OC
CUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehi
cle's placard (tire inflation
pressure label)
c::> page 226,
fig. 182.
Tires and wheels 231
2. Determine the combined weight of the driver and passengers that will be riding in
your vehicle.
3. Subtract the combined weight of the driver and passengers from
"XXX" kilo
grams or
"XXX" pounds
shown on the sticker
c::>page 226, fig. 182.
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
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 reduces the available cargo
and luggage load capacity of
your vehicle.

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 balancing, correct tire pressure and driv·
ing style.
Fig. 184 Tire tread: tread wear indicators (TWI)
_____ ___,.J)
Fig. 185 Rotating tires for more even wear
Tread Wear Indicator (TWI)
The original tires on your vehicle have
1/16 inch (1.6 mm) high "wear indicators"
c:> fig. 184 running across the tread. Depend·
ing on the make , there will be six to eight of
them evenly placed around the tire. M ar ks on
the tire sidewall (for example "TWI" or other
symbols) indicate the positions of the tread
wear indicators. Worn tires must be replaced. Different
figures may apply in other countries
c:>& .
Tire pressure
Incorrect tire pressure causes premature wear
and can cause sudden tire blow-out. For this
reason, tire pressure must be checked at least
once a month
c:> page 228.
Driving style
Driving fast around curves, heavy acceleration
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
ing :
- Tire rotation intervals may differ from the
vehicle service intervals outlined in your
Maintenance and Warranty 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 manufacturer's suggested
tire rotation intervals.
- Vehicles with front-wheel drive experience
more tread wear on the front wheels com
pa red to all wheel drive (quattro).
- Please rotate tires as shown
c:>fig. 185.
- Extra care must be taken when rotating di-
rection-specific tires
c:> page 249 .
Wheel balancing
The wheels on new vehicles are balanced .
However, various situations during everyday
driving can cause them to become unbal
anced, resulting in vibrations you can usually
feel through the steering wheel.
Unbalanced wheels must be rebalanced to
avoid excessive wear on steering, suspension
and tires. A wheel must also be rebalanced
when a new tire is installed. .,.
