Functional  limitations 
The  radar  se nsors  are  des igned  to  detect  the  le ft

that  is  critical  for  a  lane  change.  For  e xample: 
- if the  lanes  a re  narrow  or  i f yo ur are  dr iv ing  on 
the  edge  o f you r lane.  If t his is the  case,  the 
system  may  have  detected  t he vehicle  in anoth

not adjacent  to  you r cu rrent  lane. 
- if you  are  dr iv ing  through  a  curve.  Si de  assist 
may  react  to  a vehicle  that  is one  lane  over 
from  the  ad jacent  lane . 
- if side  assist  reacts  to  ot her  objects  (such  as

A WARNING 
Whee l bolts  that  a re tightened  or  repaired  in
co rrectly  can  become  loose  and  result  in loss 
o f  vehicle  control,  which  increases  the  risk of 
an  acc ident.  For the  correct  t ightening  specifi
cat io n,  refer  to¢ 
page  254 , After  changing  a 
wheel. 
- Always  keep  t he wheel  bolts  and  the 
t h reads  in  the  whee l hub  clean  and  free  of 
grease. 
- Only use  wheel  bolts  that  fit  the  rim. 
-Always  have  damaged  rims  repaired  by an  authorized  Aud i dealer  or authorized  repair 
facility . Never  repair  or  d isassemble  rims 
yo urself,  because  th is  increases  the  r isk  of 
an  accident . 
Winter  tires 
Winte r ti re s s ignificantly  improve  the  veh icle's 
h a ndling  when  d riving  in w inte r condi tions.  Be
c a use  of the ir cons tru ction  (width,  compound, 
tread  pattern),  summe r tires  provide  less  trac
tion  o n ice and  snow. 
246 
.,. Use win ter  tires  on  a ll four  wheels . 
..  On ly use  winter  tires  that  are  approved  for  yo ur 
veh icle. 
.,.  Please  note  that  the  maximum  permitted 
speed  may  be  lower  with  winter  tires¢&_ . 
Your  authorized  Audi dealer  or  authorized  re 
pa ir fac ility  can  inform  you  about  the  maxim um 
permitted  speed  for  your  t ires .

The  effectiveness  of wi nter  tires  is reduced  g reat
l y when  the  tread  is wo rn  down  to  a  depth  of 
0.157  inch  ( 4 mm).  The  chara cte ris tic s of winter 
ti res  a lso  decrease  g rea tly as  the  t ire  ages,  re
gard less  o f the  remaining  t read. 
_&. WARNING 
- Never  drive  faster  than  the  maximum  pe r
m itted  speed  for  your  tires . This  could  cause 
the  t ires  to  heat  up too  much.  This  increases 
the  risk  of an  accident  because  it  can  cause 
the  t ire  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  t ires  can  lose  t ract io n  on  black  ice . 
@ For the  sake of  the  environment 
Reinstall summer  tires  at  the  appropr iate 
time,  because  they  prov ide  better  handling 
when  roads  are  free  of snow  and  ice.  Summer 
tires  cause  less  road  no ise,  tire wear  and  fuel 
consumpt ion. 
(i_) Tips 
You can  also  use  all  season  tires  instead  of 
winter  tires . Please  note  that  in some  coun
tries  where  wint er tires  are  required,  o nly 
winter  tires  w it h t he 
& symbol  may  be  per
mi tted. 
Snow chains 
Snow  chains  improve  trac tion in the  snow. 
.,.  On ly install  snow  chai ns  on  the  fron t wheels . 
T his  applies  a lso  to  vehicles  with  a ll wheel 
dr ive*. 
- 

~ Check and correc t the  seating  of  the  snow 
chains if  necessary after  driving  a few  feet.  Fol
l ow  the  instructions  from  the  manufacturer . 
~ Note  the  maximum  permitted  speed when  driv
ing with  snow  chains.  Do not  exceed 30  mph 
(SO km/h) . 
Snow chains not  only  improve  the 
driving in win
ter  road cond itions,  but  also the 
braking. 
Use of  snow  chains is on ly permitted  with  certain 
rim/tire  combinations  due to  tec hnical  reasons . 
Check with  an authorized  Audi  dealer  or  author ized repair  facility  to  see if  you  may use snow 
cha ins. 
You must  remove  the  chains when  driving  on  roads that  are 
free of  snow.  When  roads are free 
of  snow,  snow  chains can impair  handling  and 
damage  the  t ires, and the  chains w ill  quickly  be 
destroyed . 
A WARNING 
Using  incorrect  snow chains o r installing  snow 
chains incorrect ly can  result  in loss of  vehicle 
c ont rol,  w hic h  in cr eases the  risk of  a n acci 
de nt. 
- Snow cha ins can damage  the  rims/wheel 
covers*  if  the  cha ins come  into  d irect con
tact  wi th them . Remove the  whee l cove rs* 
first.  Use  coated  snow  cha ins. 
- Usi ng snow  chai ns  tha t add  more  than 0.4 
i nch (10.5  mm)  of  he igh t ca n severely  dam
age the  wheel  ho usings and othe r vehicle 
components . 
- Do no t install  and  use s now  chains if  there  is 
a mal funct ion  in the  adaptive  air  suspen 
sion*,  because the  vehicle  height  wi ll be 
very low.  If  you d rive with  snow  chains any
way, the  wheel  ho usings and othe r vehicle 
components  can be severely damaged. 
Low  aspect  ratio  tires 
Your Aud i is factory -equipped  with  low  aspect  ra
tio  tires . These t ires have been tho rough ly tested 
and  been se lected  specifically  for  yo ur model  fo r 
Wheel s 
their  superb  performance,  road fee l and handling 
u nder  a variety  of  driving  conditions . Ask your  au
thorized  Audi  dea le r fo r more  detai ls. 
T he  low  aspect  rat io o f th ese  tires  is  indicated  by 
a n umeral  of 
55  or le ss in the  tire's  size des igna
tion . The numera l represents  the  ratio  of  the 
t ir e's s idewall  height  in  relation  to  its  tread  w idth 
expressed in  percentage.  Conventiona l tires  have 
a he ight/width  ratio  of  60  or  more. 
The performance  of  low-aspect- ratio  tires  is par
ticularly  sen sitive  to  imprope r inflat ion pres
s ure.  It  is the refore  important  that  low  aspect 
rat io tires  are  inflated  to  the  speci fied pre ssure 
and that  the  inflation  pressure i s regularly 
checked and m aintain ed. Tir e pr essures  should 
be checked at  least once a month  and  always 
b efor e a long trip 
~ page 241. 
What  you  can  do to  avo id tire  and  rim 
damage 
Low aspect  ratio  tires  can be damaged  more  eas i
ly by impact  w ith  po tholes,  curbs,  gullies  or 
ridges  on the  road,  particularly  if  the  tire  is un 
deri nflated. 
In  orde r to  m in imize  the  occurrence  of  impact 
damage  to  t he tires  of  yo ur vehicle , we  recom 
me nd that  you observe the  following  pre ca u
t ions: 
- Always  ma intain  recommended  inflat ion  pres
sures.  Check yo ur tir e pressure  every  2,000 
m iles (3 ,00 0  k m)  and add  air  if  necessary. 
- Dr ive ca refully  on  roads w it h  potholes,  deep 
gullies  o r ridges.  T he  impact  from  dr iving 
t hrough  or  over such obstacles  can damage 
your  tires.  Impac t wi th a curb  may a lso ca use 
damage  to  your  tires. 
- Afte r any impac t, immed iate ly  inspect yo ur 
t ires or  have  them  inspected  by the  nearest  au 
thorized  A udi dealer.  Rep lace a damaged  tire  as 
soon as possible. 
- Inspect your  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 ich could  eventually  cause 
tire  fa ilure.  If  you  believe that  a tire  may have 
been damaged,  replace the  tire  as soon  as pos -
sible .  .,.
