Side  assis t fu nctions  at  speeds above app rox i
ma tely  19  mph  (30  km/h). 
(D V ehicles that  are approaching 
In  certain  cases,  a vehicle  will  be  classified  as 
cr itical  for  a  lane  change 
even if  it  is still 
somewhat  far  away. The fas ter  a vehicle  ap
p ro aches,  the  sooner  the  disp lay in the  exteri
or  m irror  will  t urn  on. 
@ Vehicles traveling  with  you 
Vehicles  traveling  w ith  you  are  indicated  in the 
exterior  m irror  if they  are  classified  as  cr it ical 
for  a  lane  change.  All vehicles  detec ted  by 
side  assis t  are in dicated  by the  time  they  en
ter  your  "blind  spot",  at  the  latest. 
@ Vehicles left  behind 
If you  s low ly pass  a  ve hicl e tha t sid e ass ist  has 
dete cted  (t he  difference  in s peed  between  the 
vehicle  and  you r vehicle  is  less  than  9  mph 
(15  km/h),  the  display  in the  exter ior  mirror 
turns  on  as  soon  as  the  vehicle  enters  your 
blind  spot. 
The  display  wi ll not  t urn  on  if you  quickly  pass 
a vehicle  that  s ide  assist  has  detected  (the  dif 
ference  in speed  between  the  ve hicle  and  your 
vehicle  is  greater  than 9  mph  (15  km/h). 
Functional  lim itations 
T he  radar  senso rs are  designed  to detect  the 
left  and  right  adjacent  lanes  whe n the  road 
l anes  a re  the  normal  width.  In  certain  situa
t ions,  the  d isp lay  in the  exterior  mirror  may 
turn  on 
even though  there is no  ve hicle  locat
ed  in the  area  that  is  cr itical  for a  la ne  cha nge. 
Fo r example: 
- if  the  lanes  are  narrow  or  if your  are  driving 
on  th e edge  of your  lane.  If  this is the  case, 
the  system  may  have  detected  the  vehicle  in 
another  la ne  that  is 
not adjacent  to  you r 
cur rent  lane . 
- if you  a re  driving  throug h a  c urve . Side  assist 
may  react  to  a vehicle  that  is  one  lane  ove r 
from  the  ad jacent  lane . 
- if side  assist  reacts  to  other  objects  (such  as 
high  or  d isp laced  gua rd  rails) . 
- In  poor  weather  conditions.  The side  assist 
fu nctions  are  limited . 
Do not 
cover the  radar  sensors c::> fig.  117 with 
stickers,  depos its,  bicycle wheels  or  other  ob
jects,  because  this  will affect  the  funct ion.  Do 
not  use  s ide  ass ist  when  towing  a trailer . For 
i nforma tion  on  cleaning,  refe r to

Automatic car wash 
The vehicle can be washed  in almost  any 
modern  automatic  car wash . 
The vehicle  paint  is so  durable  that  the  vehicle 
can  normally  be  washed  without  problems  in 
an  automatic  car  wash. However,  the  effect  on 
the  paint  depends  to  a  large  extent  on  the  de
sig n of the  fac ility,  the  filtering  of the  wash 
water,  the  type  of wash  and  care  mater ial , etc. 
If the  paint  has  a  dull  appearance  afte r go ing 
through  the  car  wash  or  is scratched,  bring 
this  to  the  attention  of the  operator  immedi
ately.  If  necessary,  use  a  different  car  wash. 
The  power  top  does  not  require  special  pre
cautions  be fore  passing  through  a  car  wash. 
Howe ver, the  c ar mu st  not  be tre ated  with 
hot  w ax after th e was h  cy cle ! 
The wax  could 
adversely  affect  the  power  top  and 
even dam
age  the  fabric 
over a  period  of  time. 
The  power  top  does  not  have  to  be  washed 
ev 
ery  time  you  use  a  car  wash.  The  power  top 
can  be  spared  if the  car  wash  facility  is equip
ped  with  manually  adjustable  roof  brushes  or 
rollers . 
Before  going  through  a  car  wash,  be  sure  to 
take  the  usual  precaut ions  such  as  clos ing  the 
windows . Remove  antenna  if applicable . 
If  yo u have  installed  additional  accessories  on 
the  vehicle  -such  as  spoilers,  etc.  -it  is  best  to 
ask  the  car  wash  operator  if these  should  be 
removed . 
A WARNING 
Always  read  and  heed  all WARNINGS and 
other  information 
Q page  194. 
(D Note 
- Before  washing  the  vehicle  in an  auto
matic  car  wash,  please  make  sure  to  re
tract  t he  exterior  m irrors  to  prevent 
them  from  being  damaged. 
- Compare  the  width  of your  vehicle  with 
the  width  of  the  tunnel  at  the  fac ility. 
Cleaning  and  protec tion  195 
Washing  the  vehicle by hand 
A lot  of  water  is needed  when  washing  a  vehi
cle by hand .

.8, WARNING 
Sudden tire  failure  can  lead to  loss of  con
trol,  a crash and serious  personal  injury! 
- Never drive  a veh icle when  the  tread  on 
any tire  is worn  down  to  the  wear  indica
tors. 
- Worn  tires  are a safety  hazard, they  do  not  grip  well  on wet  roads and increase 
your  risk of  "hydrop lan ing"  and  loss of 
control. 
- Always  keep chemicals  that  can cause 
tire  damage,  such as grease, oil,  gasoline 
and brake fluid  away from  tires. 
- Tires age even if they  are not  being  used 
and  can fail  suddenly,  especially  at  high 
speeds. Tires that  are more than  6 years 
old  can only  be used in an emergency 
and then  with  special care and at  lower 
speeds. 
- Never mount  used tires  on your  vehicle  if 
you are not  sure of  their  "previous  histo
ry."  Old used tires  may have been dam
aged even though  the  damage  cannot  be 
seen that  can lead to  s udden tire  failure 
and loss of  vehicle  control. 
New tires  and  replacing  tires  and wheels 
New tires  and  wheels  have  to  be broken  in .

T he t ires and  rims  are essential  parts  of  the 
vehicle 's design . The tires  and  rims  approved 
by Audi  are spec ially  matched  to  the  charac
teristics  of  the  vehicle  and can make a major  .,..  

vehicle  handling  and  can  lead  to  a  loss  of control. 
- If  the  spare  tire  is  not  the  same  as  the 
tires  that  are  mounted  on  the  vehicle  -
for  example  with  winter  tires  -only  use 
the  spare  tire  for  a  short  period  of  time  and  drive  with  extra  care . Refit  the  nor
mal  road  wheel  as  soon  as  safely  possi
ble . 
- Never  drive  faster  than  the  maximum  speed  for  which  the  tires  on  your  vehicle are  rated  because  tires  that  are  driven 
faster  than their  rated  speed  can  fail 
suddenly. 
- Overloading  tires  cause  heat  build-up, 
sudden  tire  failure,  including  a  blowout 
and  sudden  deflation  and  loss  of  control. 
- Temperature  grades  apply  to  tires  that 
are  properly  inflated  and  not  over  or  un
derinflated. 
- For  technical  reasons it is not  always 
possible  to  use  wheels  from  other 
vehicles  -in some  cases  not  even  wheels 
from  the  same  vehicle  model. 
- If  you  install  wheel  trim  discs  on  the  ve
hicle  wheels,  make  sure  that  the  air flow 
to  the  brakes  is not  blocked.  Reduced  air
flow  to  the  brakes  can  them  to  overheat,  increasing  stopping  distances  and  caus
ing  a collision . 
- Run flat  tires  may  only  be  used  on 
vehicles  that  were  equipped  with  them 
at  the  factory.  The  vehicle  must  have a 
chassis  designed  for  run  flat  tires  and  a 
factory-installed  tire  pressure  monitor
ing  system*  that  indicates a  loss  of  tire 
pressure.  Incorrect  use  of  run  flat  tires 
can  lead  to  vehicle  damage  or  accidents. 
Check with  an  authorized  Audi  dealer  or 
tire  specialist  to  see  if your  vehicle  can  be 
equipped  with  run  flat  tires . If  run  flat 
tires  are  used,  they  must  be  installed on 
all four  wheels.  Mixing tire  types  is not 
permitted . 
0 Note 
-For technical  reasons,  it is  not  generally 
possible  to  use  the  wheel  rims  from  oth-
Tires  and  wheels  241 
er  vehicles.  This can  hold  true  for  wheels 
of  the  same  vehicle  type. 
- If  the  spare  tire is different  from  the 
tires  that  you  have  mounted  on  your  ve
hicle  (for  example  winter  tires  or  wide 
profile  tires),  then  use  the  spare  tire  for  a 
short  period  of  time  only  and  drive  with 
extra  care.  Replace  the  flat  tire  with  the 
tire  matching  the  others  on  your  vehicle  as  soon  as  possible . 
- Never  drive  without  the  valve  stem  cap . 
The  valves  could  get  damaged . 
(® For the  sake of  the  environment 
Dispose  of  old  tires  in accordance  with  the 
local  requirements. 
Uniform  tire  quality  grading 
-Tread  wear 
- Traction  AA A B C 
- Temperature  AB  C 
Quality  grades  can  be found  where  applicable 
on the  tire  side wall  between tread  shoulder 
and  maximum  section  width 9 fig. 186. 
For example: Tread  wear 200, Traction AA, 
Temperature A. 
All passenger  car  tires must  conform  to  Feder
al  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 
government  test  course. 
For  example,  a tire  graded  ISO  would  wear 
one  and  one  half  (11/2)  times  as  well  on  the  government  course  as  a tire  graded  100. 
The  relative  performance  of  tires  depends  upon  the  actual  conditions  of  their  use,  how
ever,  and  may  depart  significantly  from  the  norm  due  to variations  in driving  habits,  serv
ice  practices  and  differences  in  road  character-
istics  and  climate.

24 4  T ire s and  wheel s 
Wheel  bolts 
Wheel  bolts  must  always  be tightened  to the 
correct torque . 
The  design  of  wheel  bolts  is  matched  to  the 
factory  installed  rims.  If  differen t rims  are  fit
ted,  the  correct  wheel  bolts  with  the  r ight 
length  and  correctly  shaped  bolt  heads  must 
be  used.  This  ensures  that  wheels  are  fitted 
secure ly and  that  the  brake  system  funct ions 
correctly . 
In  ce rtain  circumstances,  you  may  not  use 
wheel  bolts  from  a different  vehicle  -even  if it 
i s the  same  model~ 
page 2 71. 
_& WARNING 
Improperly  tig htened  o r maintained  whee l 
bolts  can  become  loose  ca using  loss  of 
contro l,  a  co llision  and  serious  persona l in
jury. 
- Always  keep  the  wheel  bolts  and  the 
threads  in the  wheel  hubs  clean  so  the 
wheel  bolts  can  turn  easily  and  be  prop
erly  t ightened. 
- Never  grease  or  oil the  wheel  bo lts  and 
the  threads  in the  wheel  hubs.  They  can 
become  loose  while  driving  if greased  or 
oiled,  even  if tightened  to  the  specif ied 
torque . 
- Only use  wheel  bolts  that  belong  to  the 
rim  being  installed . 
- Never  use  different  wheels  bolts  on your 
vehicle . 
-Always  maintain  the  correct  tighten ing 
torque  for  the  wheel  bo lts  to  reduce  the 
risk  of  a wheel  loss.  If  the  tightening  tor 
que  of the  wheel  bolts  is too  low,  they 
can  loosen  and  com e out  when  the  veh i
cl e  is moving.  If  the  tightening  torque  is 
too  high,  the  whee l bolts  and  threads 
can  be  damaged  and  the  wheel  can  be
come  loose. 
@ Note 
The  spec ified  torq ue fo r the  wheel  bo lts  is 
90  ft  lbs.  (120  Nm) wi th a  toler ance  of 
± 7,4  ft  lbs. (± 10  Nm). Torque  wheel  bo lts  diagonally.  After  changing  a wheel,  the 
torque  m
ust  be  checked  as  soon  as  possi
ble  with  a torque  wrench  -preferably  by an 
a uthori zed  Audi dea ler  or  q ua lified  work
shop . 
Low aspect  ratio  tires 
Your Audi  is factory -equ ipped  w ith  low  aspect 
ratio  tires . T hese  tires  have  been  thoroughly 
tested  and  been  se lected  specifically  fo r your 
model  for  their  superb  perfo rmance,  road  fee l 
and  hand ling  under  a variety  o f driv ing  condi 
t ions . As k your  authorized  A udi  dealer  for 
more  details . 
T he  low  aspect  ratio  of  these  tires  is ind icated 
by a  numera l of 
55  or l ess in the  tire's  s ize 
designation.  The  numeral  represents  the  ratio 
of  the  tire's  sidewa ll height  in  relation  to  its 
tread  width  exp ressed  in  percentage . Conven
tiona l tires  have  a  he ight/w idth  ratio  of  60  or 
more . 
The performance  of  low-a spect-r atio  tire s is 
pa rt icul arly s ens itive to  imp ro per i nfl ation 
pressure.  It  is therefore  import ant that  low 
aspect  ratio tires  are inflated  to  the  specified  pre ssure and that  the  inflation  pressure  is 
r e gularly  checked  and  maintained . Tire pres
sur es should  be checked  at  l east  once  a 
month  and  always  before  a long  trip 
~ page  233,  Checking  tire pressure. 
What  you  can  do  to  avoid  tire  and  rim 
damage 
Low aspect  ratio  tires  can  be  damaged  mo re 
easily  by impact  w it h  potholes,  c urbs,  g ull ies 
o r  ridges  on  the  road,  pa rticul arly  if the  tire  is 
u nderinfla ted . 
In  orde r to  minimize  the  occurrence  of  impact 
damage  to  t he  tires  of your  vehi cle,  we  recom
mend  tha t you  observe  the  following  preca u
tions: 
- Always  ma inta in  recommended  inflation 
pressu res.  Check your  tire  pressure  eve ry 
2 ,000  miles  (3,000  km)  and  add  air  if neces -
sary.  ..,.
