246 Tires and wheels
The relative performance of tires depends
upon the actual conditions of their use, how­
ever, and may depart significantly from the norm due to variations in driving habits, serv­
ice practices and differences in road character­
istics and climate.
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 controlled conditions on
specified government test surfaces of asphalt
and concrete . A tire marked C may have poor
traction performance ¢.&, .
Temperature
The tempera ture grades are A (the highest),
B, and
C, representing the tire's resistance to
the generation of heat and its ability to dissi ­
pate heat when tested under controlled condi­
tions on a specified indoor laboratory test
wheel.
Sustained high temperature can cause the
material of the tire to degenerate and reduce
tire life, and excessive temperature can lead
to sudden tire failure~.&, .
The grade
C corresponds to a level of perform ­
ance which all passenger car tires must meet under the Federal Motor Vehicle Safety Stand­
ard No.
109. Grades Band A represent higher
levels of performance on the laboratory test
wheel than the minimum required by law.
A WARNING
The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning or peak traction
characteristics.
A WARNING
The temperature grade for this tire is es­
tablished for a tire that is properly inflated
and not overloaded . Excessive speed, un­
derinflation, or excessive loading, either
-
separately or in combination, can cause heat buildup and possible tire failure.
Winter tires
Winter tires can improve vehicle handling on
snow and ice. At temperatures below 45 °F (7 °C) we recommend changing to winter
tires.
In some heavy snow areas, local governments
may require true winter or "snow" tires, those
with very deeply cut tread . These tires should
only be used in pairs and be installed on all
four wheels . Make sure you purchase snow
tires that are the same size and construction
type as the other tires on your vehicle .
Your vehicle is equipped with all wheel drive,
this will improve traction during winter driv ­
ing, even with the standard tires. However, we
strongly recommend that you always equip all
four wheels on your vehicle with correctly fit­
ted winter tires or all-season tires, when win­
ter road conditions are expected. This also im­
proves the vehicle's braking performance and
reduces stopping distances.
Summer tires provide less grip on ice and
snow.
Winter tires (snow tires) must always be fitted
on all four wheels.
Ask your authorized Audi dealer or qualified
workshop for permitted
winter tire sizes . Use
only radial winter tires.
Winter tires lose their effectiveness when the
tread is worn down to a depth of
O .15 7 inch
(4 mm).
Only drive with winter tires under winter con­
ditions. Summer tires handle better when
there is no snow or ice on the roads and the
temperature is above 45 °F (7 °().
If you have a flat ti re, see notes on spare
wheel
¢page 242.
Please always remember that winter tires may
have a lower speed rating than the tires origi-
nally installed on your vehicle at the time it .,.

Maintenance
' General
Your vehicle has been designed to help keep
maintenance requirements to a m inimum.
However, a certain amount of regular mainte­
nance is still necessary to assure your vehicle's
safety, economy and reliability . For detailed
vehicle maintenance consult your Warranty
&
Maintenance booklet.
Under difficult operating conditions , for ex­
ample at extremely low outside temperatures,
in very dusty regions, when towing a tra iler
very frequently, etc., some serv ice work
shou ld be pe rformed between the intervals
specified. This applies particularly to:
- oil changes, and
- cleaning or replacing the air filter.
® For the sake of the environment
By regularly maintaining your veh icle, you
help make sure that emission standards
are maintained, thus min imiz ing adverse
effects on the environment .
Important considerations for you and

- If you must work unde rneath the vehicle
wit h the wheels on the ground, a lways
make sure the vehicle is on leve l ground,
that the wheels are always secure ly
blocked and that the engine cannot be
started.
