You can also use all season tires instead of
winter tires . Please note that in some coun­
tries where winter tires are required, only
winter tires with
the ~ symbol may be per­
mitted.
Snow chains
Snow chains not only improve the driving in win­
ter road conditions, but also the braking .
.. Only install snow chains on the front wheels.
This applies also to vehicles with all wheel
drive* .
.. Check and correct the seating of the snow
chains after dr iv in g a few feet, if necessary . Fol­
low the instructions from the manufacturer .
.. Note the maximum speed of 30 mph (SO km/
h). Note the loca l regulations.
Use of snow chains is only perm itted with certain
rim/tire combinations due to technical reasons.
Check with an authorized 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 .
{[J) 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 air suspension*, be­
cause the vehicle height will be very low. If
Wheels
you drive with snow chains anyway, the
wheel housings and other vehicle compo­
nents can be severely damaged.
(D Tips
When using snow chains, it may be useful to
switch on sport
mode¢ page 120.
Low-profile tires
Applies to: vehicles with low-profile tires
Compared to other tire/rim combinations, low­
profile tires offer a wider tread surface and a
larger rim diameter with shorter tire sidewalls.
This results in an agile driving style . However, it
may reduce the level of comfort and increase
road noise when driving on roads in poor condi­
tion.
Low -profile tires can become damaged more
quickly than standard tires when driving over
large bumps, potholes, manhole covers , and
curbs . Therefore, it is particularly important to
maintain the correct tir e pressure
¢ page 211.
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 authorized Audi
Service Facility.
Low-profile tires can wear out faster than stand­
ard tires .
Uniform tire quality grading
-Tread wear
- Traction AA ABC
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width

All passenge r ca r tires m ust conform to Federa l
Safety Requi rements in addition to these g rades.
Tread wear
The tread wear grade is a comparat ive rat ing
based on the wear rate of the t ire when tested
unde r contro ll ed conditions o n a specified gov ­
e rnmen t test co urse.
For example, a tire graded 150 would wear one
and one ha lf ( 11/2) t imes as well on the gove rn­
ment course as a tire g raded 1 00.
The relative performance of t ires depends upon
the actual condi tions of their use, howeve r, and
may depart s ignificant ly from the norm d ue to
va ria tions in driving hab its, service pra ctices and
d ifferences in road ch aract eris tics and clim ate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band

Tire pressure monitoring
system
ill General notes
Each tire, including the spare (if prov ided),
shou ld be checked monthly when cold and inflat­
ed to the i nflat ion press ure recommended by the
vehicle manufacture r on the veh icle placard or
ti re infla tion p ressure labe l. (If your ve hicle has
t ir es of a diffe rent size t han the si ze ind icated on
t h e ve hicle placard or tire i nflat io n press ure la ­
bel, you sho uld dete rm ine the proper tire in fla­
tion press ure for those tires) .
As a n ad ded safety featu re, you r vehicle has been
equipped wi th a t ire p ress ure mon itor ing system
(TPMS) t hat ill umi nates a low tire p ressure tell ­
ta le w hen one or mo re of your tires is s ignificant ­
l y under -inflated. According ly, w hen the low ti re
pressure telltale illum inates, you sho uld stop and
c h eck your t ires as soon as possible, and inflate
them to the proper pressure. Dr iv ing on a sign ifi­
cant ly under -inflated t ire ca uses the t ire to over ­
heat and ca n lead to tire fa ilu re . U nder-inflation
also red uces fue l eff ic iency a nd tire tread life,
and may affect t he ve hicl e's handling a nd s top-
ping ability.

0 0 \,;J ' Please note that the TPMS is not a substitute for
proper tire maintenance, and it is the driver's re­
sponsib ility to ma intain correct tire pressure,
even if under-inf lation has not reached the level
to trigger illum ination of the TPMS low tire pres­
sure telltale .
Your veh icle has also been equ ipped w ith a TPMS
malfunct ion indicator to indicate when the sys­
tem is not operating properly. The TPMS mal­
function indicator is combined w ith the low tire
pressure telltale. Whe n the system detects a
malfunct ion, the telltale will flash for approxi­
mately one minu te and then remain cont inuous ly
i llum inated. This sequence wi ll continue upon
subseq uen t veh icle start -ups as long as the ma l­
function exists.
When the malfunct ion i ndicator is ill uminated,
the system m ay not be ab le to detec t or sig nal
l ow tire press ure as intended. TPMS ma lfunctions
may occur for a var iety of reasons, incl uding the
installation of replacement or alternate tires or
wheels on the vehicle that prevent the TPMS
from functioning properly. Always check the TPMS malfunction telltale after rep lacing one or
more t ires or whee ls on your vehicle to ensu re
that t he replacement or alternate ti res and
wheels allow the TPMS to cont inue to func tion
p roperly.
