A WARNING
-
Overloading a vehicle can
cause loss of vehicle control,
a crash or other accident, se­
rious personal injury, and
even death.
-Carrying more weight than your vehicle was designed to carry will prevent the ve­
hicle 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 vehi­
cle within a safe distance.
-Tires on a vehicle that has
been overloaded can fail
suddenly, including a blow­
out 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 Rat­
ing.
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)
¢page 217,

2. Determine the combined
weight of the driver and pas­
sengers that will be riding in
your vehicle.

Maximum Permissible
Inflation Pressure
This number is the greatest
amount of air pressure that
should ever be put in the tire
under normal driving condi­
tions.
.&_ WARNING
-Using incorrect or unmatch­ ed tires and/ or wheels or improper tire and wheel
combinations can lead to loss of control, collision and
serious personal injury.
-Always use tires, rims and wheel bolts that meet the
specifications of original
factory-installed tires or
other combinations that have been specifically ap­
proved by the vehicle manu­
facturer.
-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 damaged even though
the damage cannot be seen
that can lead to sudden tire
failure and loss of vehicle
control.
-All four wheels must be fit­ ted with radial tires of the
same type, size (rolling cir­
cumference) and the same
tread pattern. Driving with different tires reduces vehi­
cle handling and can lead to
a loss of control.
-If the replacement tire is
not the same as the tires
that are mounted on the ve­
hicle -for example with win­
ter tires - only use the re­
placement 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 maximum speed for which
the tires on your vehicle are
rated because tires that are
driven faster than their rat-
ed speed can fail suddenly. ...

and handling under a variety of driving condi­
tions. Ask your authorized Audi dea ler for
more deta ils.
The low aspect ratio of these tires is indicated
by a numeral of
55 or less in the tire's size
designation. The numeral represents the ratio
of the tire's sidewa ll height in relation to its
trea d width expressed in percentage. Conven­
ti onal tires have a height/width ratio of 60 or
more.
The performance of low-aspect-ratio tires is
particularly sensitive to improper inflation
pressure . It is therefore important that low
aspect ratio tires are inflated to the specified
pressur e and that the inflation pressure is
regularly checked and maintained. Tire pres­
sures should be checked at least once a
month and always before a long trip
¢ page 221, Checking tire pressure.
What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more
easily by impact with potho les, curbs, gullies
or ridges on the road, particu larly if the tire is
underinflated .
I n order to minimize the occ urrence of impact
damage to the tir es of your vehicle, we recom­
mend that you observe the following precau­
tions:
- Always maintain recommended inflation
pressures. Check your tire pressure every
2,000 miles (3,000 km) and add air if neces­
sary .
- Drive carefully on roads with potholes, deep
gullies or ridges. The impact from driving
t hr ough or over such obstacles can damage
your tires. Impact with a curb may also
cause damage to your tires.
- After any impact, immediately inspect your
t ir es or have them inspected by the nearest
authorized Aud i dealer. Replace a damaged
t ir e as soo n as possible.
- Inspect your t ires every 2,000 miles (3,000
km) for damage and wear. Damage is not al­
ways easy to see . Damage can lead to loss of
air and underinflation, wh ich could eventu-
Tires and wheels 239
ally cause tire failure. If you believe that a
tire may have been damaged, rep lace the
tire as soon as possib le.
- These tires may wear more quickly than oth­
ers.
- Please also remembe r that, while these tires
deliver responsive handling, they may ride
less comfortably and make more noise than
other choices.
Reduced performance in winter/cold
season conditions
All tires are designed for certain purposes.
The low aspect ratio, ultra high performance
tires or iginally installed on your vehicle are in­
tended for maximum dry and wet road per­
formance and handling. They are not suitable
for cold, snowy o r icy weather conditions. If
you drive under those circumstances, you
should equip your vehi cle w ith all-season or
winter tires, which offer better traction under
those conditions. We suggest you use the rec ­
ommended snow or a ll-season tires specified
for your vehicle, or their equivalent.
Refer to¢
page 236 for more de tailed infor­
mation regarding winter tires.
Ti re pressure
monitoring system
ill General notes
Applies to vehicles: with tire pressure monitoring system
Each tire, including the spare (if provided),
sho uld be checked monthly when cold and in ­
flated to the inflation pressure recommended by the veh icle manufacturer on the veh icle
placard or tire inflation pressure label. (If your
vehicle has tires of a d ifferent size than the
s ize indicated on the vehicle placard or tire in­
flat io n pressure label, you should determine
the proper t ire inflation pressu re for those
tires).
As an added safety feature, your veh icle has
been equipped with a tire pressure mon itoring
system (TPMS) that illum inates a low tire
pressure te llt ale when one or more of your
tires is significantly under-inflated. .,.

According ly, when the low tire pressure te ll­
tale illuminates, you shou ld stop and check
your tires as soon as possible, and inf late
them to the proper pressure. Driving on a s ig­
n ificantly under-inflated tire causes the tire to
overheat and can lead to tire failure. Under-in­
flation also reduces fuel efficiency and tire
tread life, and may affect the vehicle's han­
dli ng and stopp ing ability.
Please note that the TPMS is not a subst itute
for proper tire maintenance, and it is the driv­
e r's responsib ility to ma inta in correct tire
p ressu re, even if under- inflation has not
reached the leve l to trigger ill umination of the
TPMS low tire pressure telltale.
Your veh icle has also been equ ipped with a
TPMS malfunction indicato r to indica te when
the system is not opera ting properly. The
TPMS mal function indicator is combined wi th
the low tire press ure telltale . When the sys­
tem detects a malfunction, the te lltale will
f lash fo r approximately one minute and then
remain cont inuous ly illuminated. This se­
quence will continue upon subsequen t vehicle
start -ups as long as the ma lfunction ex ists .
When the malfunct ion indicator is ill uminat­
ed, the system may not be able to detect or
signal low t ire pressure as intended . TPMS
malfunctions may occur for a variety of rea ­
sons , includ ing the installat ion of replace­
ment or a lternate tires or whee ls on the veh i­
cle that prevent the TPMS from funct ioning
p roperly. Always check the TPM S malf unct ion
tellta le after replacing one o r more t ires or
wheels on your veh icle to ensure that the re­
p lacement or a lternate tires and wheels allow
the TPMS to continue to function p roperly. Tire pressure indicator appears

the tire to overhea t and can lead to tire
f ailure. Under-inflation also is likely to
impair the vehicle's handling and stop­
ping ability.
- The driver is responsible for maintaining
the correct tire pressures . You must
check the t ire pressures regular ly.
- Under certain cond itions (such as a spor ­
