u. co .... N
" N .... 0 0 :c ' ~ Check and correct the seating of the snow
chains after driving a few feet, if necessary. Fol­
low the instructions from the manufacturer.
~ Note the maximum speed of 30 mph (SO km/
h). Note the loc al regulations.
Use of snow chains is only permitted with certain
rim/tire combinations due to technical reasons.
Check with an authori zed Audi dealer or author­
ized Audi Service Facility to see if you may use
snow chains .
You must remove the snow chains on roads with­
out snow. Otherwise, you could impair driving
ability and damage the tires.
A WARNING
Using incorrect snow chains or installing snow
chains incorrectly can result in loss of vehicle
control, which increases the risk of an acci­
dent.
0 Note
-Snow chains can damage the rims/wheel
covers* if the chains come into direct con·
tact with them . Remove the wheel covers*
first. Use coated snow chains.
-Using snow chains that add more than 0.4
inch (10.5 mm) of height can severely dam­
age the wheel housings and other vehicle
components.
-Do not install and use snow chains if there is
a malfunction in the adaptive air suspen­
sion, because the vehicle height will be very
low. If you drive with snow chains anyway,
the wheel housings and other vehicle com­ ponents can be severely damaged.
@ Tips
When using snow chains, it may be useful to
switch on sport mode

Low-profile tires
Appl ies to: ve hicles w ith low-profile tires
Your vehicle is equipped with low-profile tires* at
the factory . Compared to other tire/rim combina­
tions, low-profile tires offer a wider tread surface
and a larger rim diameter with shorter tire side-
Wheels
walls. This results in an agile driving style. How­
ever, it may reduce the level of comfort and in­
crease road noise when driving on roads in poor
condition.
Low-profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers, speed
bumps and curbs. Therefore, it is particularly im­
portan t to maintain the correct tire pressure
¢ page 293.
To reduce the risk of damage to the tires and
rims, drive very carefully on poor roads.
Check your wheels regularly every 2,000 mi
(3,000 km) for damage. For example, check for
bulges/cracks on the tires or deformations/
cracks on the rims.
After a heavy impact or damage, have the tires
and rims inspected or replaced immediately by
an authorized Audi dealer or authori zed Audi
Service Facility.
Low-profile tires can wear out faster than stand­
ard tires.
Summer tires are not suitable for cold weather,
snow or black ice. If you are driving in these con­
ditions, use winter or all season tires

Uniform tire quality grading
-Tread wear
-Traction AA AB C
-Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and
maximum section width
¢ page 283, fig. 264.
For example: Tread wear 200, Traction AA, Tem­
perature
A .
All passenger car tires must conform to Federal
Safety Requirements in addition to these grades .
Tread wear
The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
