Side assist functions at speeds above app roxi­
mately 19 mph (30 km/h).
@ Vehicles that are appro aching
In certain cases, a vehicle will be classified as
cr itical for a lane change even if it is still some­
what far away. The faster a veh icle app roaches ,
the sooner the d isplay in the exterio r mirror w ill
turn on .
@ Vehicles traveling with you
Vehicles traveling with you are ind icated in the
exterior m irror if they are classified as critical for
a lane change. All vehi cles detected by side assist
100
are indicated by the time they enter your "blind
spot", at the latest .
© Vehicle s you are passing
If you slow ly pass a vehicle that s ide assist has
detected (the difference in speed between the
vehicle and your vehicle is less than 9 mph (15
km/h)), the display in the exterior mirror turns
on as soon as the vehicle enters your blind spot.
The display w ill not turn on if you quickly pass a
vehicle that side ass ist has detected (the differ­
ence in speed is greater than 9 mph (15 km/h)) .
Functional limitations
The radar sensors are designed to detect the left
and rig ht adjacent lanes when the road lanes are
the norma l width. In some si tuations, the display
i n the exterior m irror may turn on even though
there is no vehicle located in the area that is criti­
ca l for a lane change. For example:
- If the lanes are narrow or if you are dr iving on
the edge of you r lane . If th is is the case, the
system may have detected a vehicle in another
lane that is
not adjacent to your current lane.
- If you are d riving through a curve. Side assist
may react to a vehicle that is one lane over
from the adjacent lane .
- If side assist reacts to other objects (such as
high or disp laced guard rai ls) .
- In poor weather conditions. The side assist functions are limited .
Do no t cover the rada r senso rs ¢
fig. 107 w it h
stickers, deposi ts, b icycle wheels or other ob­
jects, because they will impair the function . Do
not use side assist when towing a trai ler. For in­
format ion on cleaning, see
¢ page 228.
& WARNING
- Always pay attention to traffic and to the
area around your vehicle. Side assist cannot
replace a driver's attention . The driver alone
is always responsible for lane changes and
sim ila r driv ing maneuve rs .
- In some situations, the system may not function o r its function may be limited . For
examp le:

Wheel bolts and rims
Wheel bolts
Wheel bolts must be clean and loosen/t ighten
easi ly .
Rims
Rims with a bolted rim ring* or w it h bolted whee l
covers " consist of mu ltip le pieces . These compo­
nents were bolted together using specia l bolts
220
and a spec ia l proced ure. Yo u must not repair or
disassemb le them
i::> &. .
A WARNING
Wheel bo lts that are tightened or repaired in­
correct ly can become loose and resu lt in loss
of vehicle contro l, wh ich increases the risk of
an accident . For the correct tighten ing spec ifi­
cation,
see ¢ page 23 7, After changing a
whe el.
- Always keep the wheel bolts and the
threads in the wheel hub clean and free of
grease .
- Only use wheel bolts tha t fit the rim.
- Always have damaged rims repaired by an
author ized Audi dealer or authorized A udi
Serv ice Facility . Neve r repa ir o r disassemb le
rims you rself, because this increases the risk
of an a cciden t.
Winter tires
Win ter tires significant ly imp rove the veh icle's
handling when dr iv ing in winter conditions. Be­
ca use of their construction (width, compound,
tread patte rn), s ummer ti res provide less trac­
tion on ice and snow.
.,. Use winter tires on a ll four wheels .
.,. Only use winter tires that are app roved for yo ur
vehicle .
.,. Please note that the maximum permitted
speed may be lowe r with winter
tires¢ &. in

Wheels
- Traction AA A B C
- T emperature ABC
Quality grades can be found where appl icable on
the tire side wall between tread shoulder and
maximum section width
~ page 206, fig. 187.
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 contro lled conditions on a specified gov ­
ernment test course.
F or examp le, 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 actua l conditions of their use, however, and
may depart significantly from the norm due to
variations in driving habits, service practices and
d ifferences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are
AA, A, Band
C. T hose grades represent the tire's
abi lity to stop on wet pavement as measured un ­
der controlled conditions on specified govern­ ment test surfaces of asphalt and concrete. A tire
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 d iss ipate
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 tire life,
and excess ive temperature can lead to sudden
tire
fa ilure ~.&. .
The grade C corresponds to a level of perform ­
ance which a ll passenger car tires must meet un-
222
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 tract ion grade assigned to this t ire 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 tha t 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
proper ly inflated and not over or underinflat­
ed.
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 inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or
tire inflation pressure label. (If your veh icle has
t ir es of a diffe rent size t han the size ind icated on
the vehicl e placard or tire infl ation press ure la ­
bel, you sho uld determine the proper tire infla­
tion pressure for those tires).
As an added safety featu re, you r vehicle has been
equipped with a tire pressure monitoring system
(TPMS) that illuminates a low tire pressure tell ­
ta le when one or more of your tires is significant­
l y under-inflated. According ly, w hen the low tire
pressure telltale illuminates, you should stop and
check your t ires as soon as possible, and inflate
them to the proper pressure. Dr iving on a
