Side  assist  functions  at  speeds  above  approxi
mately  19  mph (30  km/h). 
@ Vehicles that  are approaching 
In  certain  cases,  a vehicle  will  be  classified  as 
critical  for  a  lane change  even  if it is  still  some
what  far  away.  The faster  a  veh icle  app roaches, 
the  sooner  the  display in the  exterio r mirror  w ill 
turn  on. 
@ Vehicles traveling  with  you 
Vehicles  traveli ng with  you  are  ind icated  in  the 
exterior  mi rror  if they  are  classified  as  critical  for 
a  lane  change.  All vehicles  detected by side  assist 
Audi side  assist 
are indicated  by the  time  they  enter  your  "blind 
spot",  at  the  latest. 
© Vehicles  left  behind 
If you  s low ly pass  a  vehi cle that  side  assist  has 
de tected  (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. 
T he  display  w ill not  turn on if you  quickly  pass  a 
vehicle  that  side  assist  has  detected  (the  differ ence  in speed  between  the  vehicle  and  your  vehi
cle  is greater  than  9  mph  (15  km/h)) . 
Functional  limitations 
T he  radar  sensors are  designed  to  detect  the  left 
and  right  adjacent  lanes  when  the  road  lanes  are 
the  normal  width . In  certain  situations,  the  dis
play  in the  exterior  mirror  may  turn  on  even 
though  there  is no  vehicle  located  in the  area 
that  is  critical  for  a  lane  change.  For  example: 
- if the  lanes  are  narrow  or  if your  are  driving  on 
the  edge  of your  lane. If this  is the  case,  the 
system  may  have  detected  the  vehicle  in anoth
er  lane  that  is 
not adjacent  to  your  current lane. 
- if you  are  driving  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  d isplaced  guard  rai ls) . 
- In  poor  weather  conditions.  The  side  ass ist 
functions  are limited. 
Do  not  cover  the  radar  sensors 
c:> fig. 106 with 
stickers,  deposits,  bicycle wheels  or  other  ob
j ects,  because  th is will affect  the  f unction . Do not 
use  side  assist  when  towing  a trailer.  For  infor
mation  on  cleaning,  refer  to 
c:> page  184. 
A WARNING 
=  -
-Always pay  attention  to  traffic  and  to  the 
area  around  your  vehicle.  S ide  assist  cannot 
replace  a  driver's  attention.  The driver  alone 
is  always  responsibl e  for  lane changes  and 
sim ilar  drivin g maneuvers .

and a special  procedure.  You must  not  repair  or 
disassemble them¢&. . 
A WARNING 
Wheel  bolts  that  are tightened  or  repaired  in
correctly  can become  loose and  result  in loss 
of  vehicle  control,  which  increases the  risk  of 
an accident.  For the  correct  t ightening  specifi 
cation,  refer  to ¢ 
page  22 7, After  changing  a 
wheel . 
-Always  keep the  wheel  bolts  and the 
threads  in the  wheel  hub  clean and free  of 
grease. 
- Only  use wheel  bolts  that  fit  the  rim . 
- Always  have damaged  rims  repaired  by an 
authorized  Audi  dealer  or authorized  Aud i 
Service Facility . Never repair  or  disassemble 
rims  yourself,  because  this inc reases the  risk 
of  an  accident. 
Winter  tires 
Winter  tires  s ignificantly  improve  the  vehicle's 
handling  when  driving  in winter  conditions . Be
cause of  their  construction  (width,  compound, 
tread  pattern),  summer  tires  provide  l ess trac
tion  on  ice and snow. 
.,.  Use  winter  tires  on  all  four wheels. 
.,.  Only  use winter  tires  that  are approved  for  your 
vehicle. 
.,.  Please note  that  the  maximum  permitted 
speed  may be lower  with  winter  tires 
q .&,. . An 
authori zed Audi  dealer  or  authori zed Audi  Serv
ice Facility  can inform  you about  the  maximum 
permitted  speed for  your  tires . 
.,.  Check the  tire pressure  after  install ing wheels 
q page  215. 
The effectiveness  of  winter  tires is reduced  great
ly when  the  tread is worn  down  to  a depth  of 
0 .157  in  (4  mm).  The  characteristics of  winter 
tires  also decrease  greatly  as the  tire  ages, re
gardless  of  the remaining  tread. 
A WARNING 
- Never drive  faster  than  the  maximum  per
mitted  speed  for your  tires.  This could cause 
the  tires  to  heat up too  much.  This increases 
220 
-
the  risk of  an accident  because it  can cause 
the  tire  to  burst. 
- Always adapt  your  driving  to  the  road  and 
traffic  conditions . Drive carefully  and  reduce 
your  speed on  icy or  slippery  roads . Even 
winter  tires  can  lose traction  on  black  ice . 
@ For the  sake of  the  environment 
Reinstall  summer  tires  at  the  appropriate 
time,  because they  prov ide  better  handling 
when  roads  are free  of  snow  and  ice. Summer 
tires  cause less road  noise, tire  wear  and fuel 
consumpt ion . 
(D Tips 
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  w ith  the ~ symbol  may be per
mitted. 
Snow  chains 
Snow  chains improve traction in the snow . 
.,. 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 if  necessary after  driving  a few  feet.  Fol
low  the  instructions  from  the  manufacturer. 
.,.  Note  the  maximum  permitted speed when  dr iv
ing with  snow  chains.  Do not  exceed 30  mph  (SO km/h). 
Snow cha ins  not  only  improve  the 
driving in win
ter  road  conditions,  but also  the 
braking  . 
Use of  snow  chains  is only  permitted  with  certain 
rim/tire  combinat ions due  to  technical  reasons . 
Check  with an author ized Audi  dealer  or  author
ized  Audi  Service  Facility  to see if  you  may  use 
snow chains. 
Use 
fine-mesh  snow  chains. They must  not  add 
more  than  0.53  inch  (13.5  mm)  in  height,  includ
ing  the  chain  lock. 
You must  remove the  chains when  driving  on 
roads  that are 
free of  snow . When  roads  are free  ..,.

A WARNING 
Using  incorrect  snow  chains  or  installing  snow 
chains  incorrect ly can  result  in  loss  of  vehicle 
co ntrol,  which  increases  the  risk  of  an  acc i
dent . 
Snow  chains  can  damage  the  r ims/wheel  cov
ers*  if the  chains  come  into  d irect  contact 
w ith  them . Remove  the  wheel  covers*  first. 
Use  coated  snow  chains .

What  you  can  do  to  avoid  tire  and  rim 
damag e 
Low  aspect  rat io tires  can  be  damaged  more  easi
ly by  impact  with  potho les,  curbs,  gull ies  or 
Wh eel s 
ridges  on  the  road,  particular ly if the  tire  is un 
deri nflated. 
In  orde r to  min imi ze  the  occurrence  of  imp act 
damage  to  the  tires  of  yo ur vehicle , we  recom
mend  that  you  observe  the  following  preca u
tions: 
- Always  ma intain  recommended  inflat io n  pres
sures.  Check yo ur ti re  pressure  every  2,000 
miles  (3,000  km)  and  add  air  if necessary . 
- Dr ive ca refully  on  roads  w ith  po tholes,  deep 
gullies  or  ridges . The  impac t from  dr iving 
through  or  over  such  obstacles  can  damage 
your  tires.  Impact  with  a  curb  may  a lso  cause 
damage  to  your  tires. 
- After  any  impact,  immediate ly inspect  your 
tires  or  have  th em  inspected  by th e nearest  au 
thorized  Audi dealer.  Replace  a damaged  tire  as 
soon  as  possible. 
- Inspect  you r tires  every  2,000  m iles  (3,000  km) 
for  damage  and  wear.  Damage  is  not  a lways 
easy  to  see . Damage  can  lead  to  loss  of  air  and 
underinflation,  wh ic h  could  eventually  cause 
tire  fa ilure.  If you  believe  that  a tire  may  have 
been  damaged , replace  the  tire  as  soon  as  pos
sib le. 
- These  tires  may  wear  more  quickly  than  others . 
- Please  also  remember  that,  while  these  tires 
delive r responsive  ha ndling,  they  may  ride  less 
comfortably  a nd  make  more  noise  than  other 
choi ces. 
Reduced  perfo rmance  in winter /cold  se ason

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 
c::> page 205, fig. 167. 
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  (11/2)  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 
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  tire  life, 
and  excessive  temperature  can  lead to  sudden 
tire  failure 
c::> .&. . 
222 
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. 
Tire  pressure  monitoring  system 
(l) General  notes 
App lies to  vehicles : wit h tire  pressure  mo nitori ng syste m 
Each  tire,  including  the  spare  (if provided), 
should  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  vehicle  has 
tires  of  a  different  size  than  the  size  indicated  on 
the  vehicle  placard  or  tire  inflation pressure  la
bel,  you  should  determine  the  proper  tire  infla
tion  pressure  for those  tires) . 
As  an added  safety  feature,  your  vehicle  has been 
equipped  with  a  tire pressure  monitoring  system
