& WARNING (co ntinued )
• Only when all tire s on the vehicle are filled to the correct pre s­
sure, the tire pressure monitoring sy stem* can work correctly .
• The u se 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 pre ssure monitoring system *.
• Always inflate tires to the recommended and correct ti re pre s­
sure before driving off.
• Driving with underinflated tire s bend more , letting them get
too hot resulting in tread separat ion, sudden tire failure and loss
of control.
• Excessive speed and /overload ing 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 neare st service station
to check the tire pressure and add air as requ ired.
0 Note
Dr iv ing without valve stem caps can cause damage to the tire valves.
T o preven t this, a lways make su re t hat fac tory ins talle d va lve stem
caps on all wheels a re securely mo unted on the valve.
'£> For the sake of the environment
Under inflated t ires will a lso increase the fuel consumption .•
Tires and vehicle Load Limits
T here are lim its to the amount of load or we ight that any vehicle a nd
any t ire can c arry . A veh icle t hat is over loaded w ill not hand le well an d

veh icle co ntro l, bu t ca n also d amage important p art s o f the ve hicl e
and can lead to sudden ti re failure, including a blowout and sudden
deflation that can cause the vehicle to crash.
Your safety a nd tha t of you r passe ngers also depe nds o n mak ing s ure
that load limits are not exceeded. Vehicle load incl udes everybody
and everyt hing in and on t he ve hicle. T hese lo ad lim its are techn ic a lly
referred to as the vehicle's
Gross Vehicle Weight Rating ("GVWR").
Th e "GVWR" includes the weight of the basic vehi cle, all facto ry
installed accessories, a fu ll tank of fue l, o il, coo la nt and other fluids
plus maxim um loa d. Th e maxim um loa d includes t he nu mber of
passeng ers th at t he ve hicl e is intended to car ry ("sea ting capa city ")
with an ass umed weig ht of 150 lbs . (68 kg) for each passenger at a
design ated seating posit ion a nd the to tal weig ht of any luggage in
the vehicle. If yo u tow a tra iler, the weight of the trailer hitch and the
t ongue weig ht of the lo ad ed t railer mus t be include d as pa rt of the
vehicle load.
Th e
Gross Axle Weight Rating ("GAWR") is the maximum load that
can be a pplied at each of t he ve hicle's two axles .
The Gross Vehicle We ight Rating and the Gross Ax le We ight Rating
are li sted on the safety comp lia nce s tick er label loca ted either on the
dr ive r's side B-pilla r o r on the inside of the fuel filler flap . Aud i has

page 181,
"Safety be lts".
Th e fact t hat there is an upper lim it to your v eh icle 's Gross Vehicle
Weight Rating means that t he tota l weight of whatever is being
c a rried in th e veh icle ( in cl ud ing the w eight of a t railer hitch and the
tongue weight of the loaded tra iler) is limited. The mo re passengers
in the veh icle or p assengers who are heavier th an the sta ndar d

-Tires and wheels
in. 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.
Steps for Determining Correct
Load Limit
1.Locate the statement "THE COMBINED WEIGHT OF OCCUPANTS AND CARGO
SHOULD NEVER EXCEED XXX KG OR XXX LBS"on your vehicle's placard (tire infla­
tion pressure label)==>
page 295J
fig. 212.
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==>
page 295J fig. 212.
4. The resulting figure equals the available amount of cargo and luggage load
capacity. For example, if the
"XXX"
amount equals 1400 lbs. and there will
be five 150 lbs. passengers in your
vehicle, the amount of available cargo
and luggage load capacity is 650 lbs. (1400- 7 SQ (5
X 150) = 650 lbs.) ~

_________________________________________ T_ i_re _ s_a _n_ d_ w_ h_e _e _l_s _ ..... fflll
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 trailer will be transferred
to your vehicle. Consult this manual to
determine how this reduces the available
cargo and luggage load capacity of your
vehicle.
Check the tire sidewall(~
page 303~
fig. 216) to determine the designated
load rating for a specific tire .•

Tire pressure
Incorrect tire pressure causes premature wea r a nd can cause sudden
t ire blow-out. For this reason, ti re p ressure must be checked at least
once a month ~
page 297.
Driving style
Driving fast around curves, heavy acce le ra tion and hard brak ing
increase tire wear .
Rotating tires for more even wear
For all four tires on your veh icle to have the same service life, we
re commend that the fron t and re a r tires are rotate d according to the
tire manufact urer's suggested tire rotation interva ls . Please
remember the fo llow ing:
• Tir e rotat ion inte rvals may differ from t he ve hicl e service intervals
outlined in your Maintenance and War ranty Booklet .
• T he longer one tire is used in one location on the veh icle, the more
it wears at certa in points; therefore, we recommend that you follow
t he t ire m anufac ture r's suggested tire rotation in terva ls.
• V ehicles with front-whee l drive expe rience mo re tread wea r on t he
fron t wheels compa red to all-whee l drive (quattro
® ).
• Please rotate tires as s hown ~fig. 215.
• Extra care must be taken when rotating d irection-specific tires
~ page 321.
Wheel balancing
The w heels on new vehicles are balanced. Howeve r, va rious sit uat io ns
dur ing eve ryday dr iv ing can cause them to become unbalanced,
re su lt ing in v ibr ations yo u can usually fee l throug h the steering
wheel.
Unbalanced wheels must be rebalanced to avoid excessive wea r on
steeri ng, suspension and t ires . A wheel must also be rebalanced
w hen a new tire is installed.
Incorrect wheel alignment
Incorrec t whee l alignment can ca use excessive tire wear, impai ring
t he sa fety of the veh icle . If tires show excess ive wear, have the wheel
alignment checked by an authorized A udi dealer or qualified wo rk­
shop .
All wheel drive
Vehicles w ith q uattro ® must always have ti res of the same size,
const ructio n and trea d type. For details see~
page 242 .
& WARNING
Sudden tire failure can lead to loss of control , a crash and serious
personal injury!
• Never drive a vehicle when the tread on any tire is worn down
to the wea r ind icato rs.
• Worn tire s are a safety hazard, they do not grip well on wet
roads and in crease your risk of "hydroplaning" and lo ss of control.
• Always keep chemicals that can cause tire damage, such as
grease , oil , gasoline and brake fluid away from tires.
• 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 tire s on your vehicle if you are not sure of
their "previous history ." Old used tires may have been damaged
even though the damage cannot be seen that can lead to sudden
tire failure and loss of vehicle control. •

=> & .
We recommend that all work on t ires and wheels be performed by an
authori zed Au di deale r. They are fam il ia r with recommended proce­
dures and have the necessary special tools and spare parts as well as
the proper facilities for disposing of the o ld tires.
Authorized Aud i dea lers have the necessary info rmation about tech­
nical requirements for insta lling or changing tires and rims .
Replacing tires and wheels
Tires should be replaced at least in pa irs and not ind iv idually (for
example both front tires or both rea r tires together) .
Be sure to read and heed the in formation to the tire pressure mon i­
t o ring system *=>

& WARNING
• Using incorrect or unmatched tires and/ or wheels or improper
tire and wheel combination s can lead to loss of control, collision
and serious personal injury.
• Always u se tire s, rim s and wheel bolts that meet the specifica­
tions of original factory -installed tires or other combinations that
have been specifically approved by the vehicle manufacturer.
• Tires age even if they are not being used and can fail suddenly,
e specially at high speed s. Tires that are more than 6 years old can
only be used in an emergency and then with special care and at
lower speed s.
• Never mount used tires on your vehicle if you are not sure of
their "previous history ." Old u sed tires may have been damaged
eventhoughthedamage cannotbeseenthatcanleadtosudden
tire failure and loss of vehicle control.
• All four wheels must be fitted with radial t ires of the same
type , size (rolling circumference ) and the same tread pattern .
Driving with different tires reduces vehicle handling and can lead
to a loss of control.
• If the spare ti re is not the same as the t ires that are mounted
on the vehicle -for example with winter tires -only use the spare
tire for a short period of time and drive with extra care. Refit the
normal road wheel as soon as safely possible .
• Never drive faster than the ma ximum speed for which the tires
on your vehicle are rated becau se tire s that are driven faster than
their rated speed can fail suddenly .
• Overloading tire s cau se heat build-up, sudden tire failure,
including a blowout and sudden deflation and loss of control.
• Temperature grades apply to tires that are properly inflated
and not over or unde rinflated.
• For technical reasons it is not always possible to u se wheels
from other vehicles- in some cases not even wheels from the same
vehicle model. ..,_

• Winter t ires have ma ximum speed rating that may be lower
than your vehicle' s maximum speed .
• Never drive faster than the speed for which the winter or other
tires installed on your vehicle are rated .
& WARNING
Always adjust your driving to the road and t raffic conditions.
Never let the good ac celeration of the winter tire s and all-wheel
drive tempt you into taking extra risks . Always remember:
• Wh en braking, an alt-wheel drive vehicle handle s in the same
way as a front drive vehicle.
• Drive carefully and reduce your speed on icy and slippery roads,
even w inter tires cannot help under black ice conditions.
