Traffic light information
Applies to vehicles w ith Audi connect (Infota inment)
Fig. 185 Examp le : display of a speed recommendat ion
Fig . 186 Example: display of an estimated wa it time
The traffic light information ll gives you a speed
recommendation, at which to drive through the
next green traffic light
(Dr=:> fig. 185 or informs
you of the wait time at the next red light @. The
traffic light information can be displayed in the
driver information system, in the status line of
the Audi virt ual cockpit* or in the head -up dis­
play*.
General information
The traffic light information is subject to certain
system limitat ions and may be unavailable or on­
ly partially available in the following situations:
- when the perm itted speed lim it is exceeded
- if the next traffic light is less than 100
ft (30
m) away
- if the estimated wait t ime at a red light is less
than four seconds
- if there is no traffic light data available
- if the data connection was interrupted

:E: ' th e risk of an accident because it can cause
the tire t o burst.
- Always adapt yo ur drivi ng to the road and
traff ic conditions. Drive carefully and red uce
your speed on icy or slippery roads. Even
winter tires can lose traction on black ice.
@ For the sake of the environment
Reinstall summer ti res at the appropriate
time, because they provide better handling
when roads are free of snow and ice. Summer
tires cause less road noise, t ire wear and fuel
consumption.
(D Tips
You can also use all season tires instead of
w inter tires . Please note that in some coun­
tries where w inter t ires are required, only
w inter t ires with the
die. symbol may be per­
m itted.
Snow chains
Snow chains no t only imp rove the driving in wi n·
t er roa d cond itions, but a lso the brak ing.
" Only insta ll snow chains o n the
front wheels .
" Check and cor rect the sea ting of the snow
chains after dr iv ing a few feet, if necess ary. Fo l­
low the ins truc tions from the ma nufa cturer .
" Note the maximum pe rmit ted speed w hen driv ­
ing with snow chains . Do not exce ed 30 mph
(SO km/h).
Use of snow chains is only pe rm itted with certain
rim/ti re combinations due to tec hnical reasons .
Chec k with an authorized A udi d ealer or author­
ized A udi Service F acili ty to see if yo u may use
snow chains.
Use
fine-mesh snow chain s. They must not add
mo re t han 0.53 in (13 .5 mm) in height , including
the chain lock .
You mus t remove the snow c hains on roads with ­
out snow . Otherw ise, you could impair dr iving
abi lity and damage the tir es .
Wh eel s
A WARNING
Using incorrect snow chains or install ing snow
cha ins incorrectly can resu lt in loss of veh icle
control, which increases the risk of a n acci­
dent.
(D Note
- Snow chains can damage the rims/wheel
cove rs* if the chains come into direct con ­
t act with them . Remove the wheel covers*
first . Use coa ted snow cha ins .
- Do not install and use snow c hains if the re is
a malfu nction in the a ir suspension*, be­
cause the ve hicle height w ill be very low . If
yo u dr ive w ith snow chains anyway, the
w hee l ho usings and other ve hicle compo­
nents can be seve rely damaged.

Low-profile tires
Applies to: vehicles with low-profile tires
Your vehicle is equipped with low -profi le tires* at
the factory . Compared to other tire/rim combina­
tions, low-prof ile tires offer a w ider tread surface
and a larger rim diameter with shorter tire side­
walls. This results in an agile dr iv ing style. How­
ever, it may reduce the level of comfort and in ­
c rease road noise when driving on roads in poo r
cond it ion.
Low-profile t ires can become damaged more
quickly than standard tires when dr iving over
la rge bumps, potholes , manhole covers, speed
bumps and curbs. Therefo re, it is particularly im­
po rtant to mainta in the co rrect ti re pressure
q poge 343.
To reduce the risk of damage to the tires and
r ims, drive very caref ully on poor roads.
Check your wheels regu larly every 2,000 mi
(3,000 km) for damage . For example, chec k for
bulges/cracks on the tires or deformations/
c racks on the rims . .,..

Wheels
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.
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 A B C
- Temperature ABC
Quality grades can be found where applicable on
the tire side wall between tread shoulder and maximum section width
¢ page 333, fig. 273.
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
under controlled conditions on a specified
gov­
ernment test course .
For example, a tire graded 150 would wear one
and one half
(1 1/2) times as well on the govern­
ment course as a tire graded 100.
The relative performance of tires depends upon
the actual conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics 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 un­
der controlled conditions on specified govern­ ment test surfaces of asphalt and concrete . A tire
350
marked C may have poor traction performance
¢_& .
Temperature
The temperature grades are A (the highest), B,
and C , representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions on
a specified indoor laboratory test wheel.
Sustained high temperature can cause the mate­
rial of the tire to degenerate and reduce ti re 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 un­
der the Federal Motor Vehicle Safety Standard
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, cor­
nering, hydroplaning or peak traction charac­
teristics.
A WARNING
The temperature grade for this tire is estab­
lished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla ­
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.
A WARNING
Temperature grades apply to tires that are properly inflated and not
over or underinflat­
ed.
