& WARNING
• Using incorrect or unmatched tires and I 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 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,
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 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.
& WARNING (continued)
• All four wheels must be fitted with radial tires 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 tire is not the same as the tires that are mounted
on the vehicle - for e xample 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 maximum speed for which the tires
on your vehicle are rated because tires that are driven faster than
their rated speed can fail suddenly .
• Overloading tires cause 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 underinflated .
• For te chnical reasons it is not always possible to use wheels
from other vehicles -in some cases not even wheels from the
same vehicle model.
• If you install wheel trim discs on the vehicle wheels, make sure
that the air flow to the brakes is not blocked. Redu ced airflow to
the brakes can them to overheat , increasing stopping distances
and causing a collision.
• Run flat tires may only be used on vehicles that were equipped
with them at the fa ctory . The vehicle must have a chassis designed
for run flat tires and a factory-installed tire pressure monitoring
system * that indicates a loss of tire pressure . Incorre ct use of run
flat tires can lead to vehicle damage or accidents . Check with an
authorized Audi dealer or t ire specialist to see if your vehicle can
be equipped with run flat tires .
If run flat tires are used, they must
be installed on all four wheels . Mixing tire types is not permitted. .,

0 Note
• For technical reasons, it is not genera lly possible to use the
whee l rims from other vehic les. This can hold true for wheels of the
same vehic le type.
• If the spare tire is different from the tires that you have mounted
on your vehicle (for example winter tires or wide p rofile t ires), then
use the spare tire for a short period of time only and drive with extra
care. Rep lace the flat tire with the tire matching the others on your
vehicle as soon as possible.
• If you put d ifferent wheels and tires on your veh ic le (e.g. w inter
whee ls and tires), you must be certain that the wheels and tires are
compatible with the tire p ressure monitor ing system*. Otherwise
the system wi ll register a malfunction and a fau lt message wil l be
displayed. For more infor mation, contact your author ized Audi
dea ler.
0 Note
• When insta lling new tires, be carefu l not to damage the va lves or
t ire p ressu re mon itoring system* sensors .
• Never drive without the va lve stem cap. The va lves could get
damaged.
• I f the sensors must be replaced, then the valve must also be
replaced at t he same t ime.
Dispose of o ld tires in accordance with the local requ irements .•
Uniform tire quality grading
• Tread wear
• Traction AA A B C
• Temperature A B C Qua
lity grades can be found where applicable on the tire side wall
b etween tread shoulder a nd maximu m section width =>
page 255,
fig. 184.
For example : Tread wear 200, Traction AA , Temperature A.
All passenger car tires must conform to Federa l Safety Require ­
ments in addit ion to these grades.
T read wear
The tread wear grade is a comparative rating based on the wear rate
o f t he tire when tes ted under contro lled condit ions on a specified
government test course.
F o r example, a tire g raded 150 would wear one and one half (1 1 /2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual condi ­
tions o f the ir use, however, and may depart sign ificantly from the
norm due to variations in driving habits, service practices and differ ­
ences in road characterist ics and c limate .
Traction
The traction grades, from highest to lowest, are AA, A, Band C.
Those grades represent the tire 's ability to stop on wet pavement as
measured under contro lled cond itions on specified government
test surfaces of asphalt and concrete. A tire marked C may have
poor t raction performance =>& .
Temperature
The temperature grades are A (the highest), B, and C, represent ing
the tire 's resistance to the generation of heat and its ability to dissi ­
pat e heat when tested u nder con tro lled co nditions on a specified
indoor laboratory test wheel.
Sustained high tempera ture can cause the material of t he ti re to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure=>& .
The grade C corresp onds to a level of performance which all
passenger car tires must meet under the Federa l Motor Vehicle

personal injury to passengers in the vehicle in an accident or
sudden maneuver .
• Never use the jack supplied with your Audi on another vehicle,
particularly on a heavier one. The jack is only suitable for use on
the vehicle it came with. •

The various electrical circuits are protected by fuses. The fuses are
clustered in a centralized unit. The unit is located behind the face
panel at the end of the instrument panel. The crank for operating
the sunroof in case of a power failure is a lso stored behind the face
panel
~ page 49.
Two spare fuses and a sticker identifying the fuses are located on
the inside of the fuse box cover.
You are well advised to keep a supply of spare fuses in your vehicle .
Fuses with the proper ampere ratings are available at your autho ­
rized Audi dealer.
& WARNING
Never replace a fuse with one that has a higher amperage rating.
• A fuse with a too high amperage could damage the electrical
part and cause a fire .
0 Note
• On no accoun t should fuses be repaired (e.g . patched up with tin
foil or wire) as this may cause serious damage elsewhere in the elec­
trical circuit or cause fire.
• If a fuse blows repeatedly, do not keep replacing it. Instead, have
the cause for the repeated short circuit or overload tracked and
fixed. •
