Snow chains not only improve the driving in win -
ter road conditions, but also the broking.
Use of snow chains is only perm itted with certain
rim/t ire combinations due to tec hnical reasons.
Check with an authorized Audi dealer or author-
ized repair faci lity to see if you may use snow
chains.
The snow chains must have
low-profile
lin ks and
must not be thicker than 0.4 inch (10.S mm), in-
cluding the lock.
You must remove t he chains whe n driving on
roads that are
free
of snow. When roads are free
of snow, snow chains can impair handling and
damage the tires, and the chains wi ll quickly be
destroyed .

WARNING
Using incorrect snow chains or insta l ling snow
chains incorrectly can result in loss of vehicle
cont rol, which increases the risk of an acci-
dent .

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 t here is
a malfunct ion in t he adaptive air suspen-
sion, because the vehicle height will be very
low. If you drive wi t h snow chains anyway,
the wheel housings and other vehi cle com-
ponent s can be severely damaged .

Low aspect ratio tires
Your Audi is factory-equipped with low aspect ra-
tio tires . These ti res have been tho roughly tested
252
and been selected specifica lly for your mode l for
their superb performance, road fee l and hand li ng
under a var iety of dr iving condit ions. Ask your au-
thori zed Audi dealer fo r more details.
The low aspect rat io of these tires is indica t ed by
a numera l of
55 or less
in the tire's size designa-
t ion . The numera l represents the ratio of the
tire's sidewall height in relation to its tread width
expressed in percentage. Convent ional tires have
a height/width ratio of 60 or more .
The performance of low-aspect -ratio tires is par-
t icularly sensitive to improper inflation pres-
sure. It is the refore important that low aspect
ratio tire s are inflated to the specified pressure
and that the inflation pressure is regularly
checked and maintained . Tire pressures should
be checked at least once a month and alway s
before a long trip

What you can do to avoid tire and rim
damage
Low aspect ratio tires can be damaged more easi-
ly by impact with potholes, curbs, gullies or
ridges on the road, particularly if the tire is un-
derinflated.
In orde r to mi nimi ze t he occurrence of impact
dam age to the tires of your vehicle, we recom-
mend tha t you observe the following precau-
tions:
- Always maintain recommended inflation pres-
sures. Check your t ire pressure every 2,0 00
m iles (3,000 km) and add air if necessary.
- Drive carefully on roads w ith potholes, deep
gullies or ridges. The impact from dr iving
through or over such obstacles can damage
your tires. Impact with a curb may also cause
damage to your ti res.
-After any impact, immediate ly inspect you r
tires or have them inspected by the nearest au-
thorized Audi dealer. Replace a damaged tire as
soon as possible.
- Inspect your tires every 2,000 mi les (3,000 km)
for damage and wear. Damage is not always
easy to see. Damage can lead to loss of air and
underinflation, wh ich could eventually cause
tire fa il ure . If you beli eve that a tire may have
