Seats  and storage 
Attach  the roof  rack  only  at the  attachment 
points  on  the  roof railing.  On  the  inside of the 
roof  railing  there  are  two  holes  for  attaching  the 
rear  end of the  roof  rack.  To prevent  confusing 
the  front  and  rear  roof  rack attachments,  there 
are  three  holes  on  the  left  and  two  holes  on  the 
right  for  mounting  the  front  part  of  the  roof  rack 
~ fig . 80. 
The  roof  racks  have  a sticker  on  the left  side un
derneath  to  identify  front  and  rear . 
A WARNING 
When  installing  the roof rack,  make  sure  the 
sticker  is on  the  left  side  of  the  vehicle  and 
faces  the  stamped  arrow  in the  drive  direc
tion.

The  roof  rack  set  consists  of  a front  and  rear  roof

cover profile  and  a socket  wrench. 
~ Open  the  cap (D c:> fig. 82. 
~ Before  mounting  the  roof  rack,  use  the  socket

~ Clean  the  attachment  points  on  the  roof  railing 
as  well  as  the  roof  rack  rubber  washers@. 
~ Carefully  place  the  roof  rack over the  holes  in 
the  roof  railing 
c:> fig. 81. 
~ Place  the  pins@ into  the holes.  The  claw® 
must  engage  into  the  edge  of  the  roof  railing . 
~ Make sure  the  rubber  washer© lays  flat  on  the 
roof  railing . 
~ Tighten  the  left  and  right  screws  using  the 
socket  wrench @ in direction @. 
~ To  reach  the 4 ft lb (6  Nm) tightening  specifi 
cation  needed,  both  arrows  on  the  socket 
wrench  must  align . 
~ Repeat  this  procedure  on  the  second  roof  rack. 
A WARNING 
Check all the roof  rack  connections  each  time 
before  each  trip  and  re-tighten  or  re-adjust  if 
necessary . 
If you  are  going  to  be  driving  or 
rough  terrain,  you  will  have  to  check  the  at
tachments  more  often.  If you  do  not  do  this, 
the  risk  of your  luggage coming  loose  and 
falling  off  is greater. 
(D Note 
The  pins  and  the  roof  rack claws  must  engage 
securely  into  the  holes and  into  the  edge  of 
the  roof  railing  when  you  tighten the  screws! 
(D Tips 
You can  adjust  the  width  of the  roof rack  by 
using  a  hexagon  wrench  and  turning  the 
screws  on  the  top.  Let your  authorized  Audi 
dealer  help  you  with  this.

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

that  is  critical  for  a  lane  change.  For  example: 
- 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  your  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  adjacent  lane. 
- if s ide  assist  reacts  to  ot her  objects  (such  as

- To reduce  the  risk of  cuts,  protect  yourself 
from  sharp  metal  components  when  wash

- After  washing  the  vehicle,  the  brak ing  effect 
may  be  delayed  due  to  mo isture  on  the

- If  you  wash  t he vehicle  in an  automatic  car

- T o  red uce the  risk  of d am age  to  the  s urf ace, 
do  not  use  insect  removing  sponges,  k itche n

- Mat te finish  painted  veh icle  components: 
- To  reduce  the risk of  damage  to  the  sur-

- Never  use  protective  wax.  It can  destroy 
the  matte  finish  effect . 
- Do not  place  any stickers  or  magnetic

@ For the  sake of  the  environment 
Only wash  t he vehicle  in facilities  s pec ially de

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 acc ident.  For the  correct  tightening  specifi 
cation,  see  ¢ 
page  2 56, 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  r ims  repa ired by an 
authorized  Audi  dealer  o r autho rized Aud i 
Service Facility . Never repair  or  d isassemble 
rims  yourself,  because this  increases  the  risk 
of  an accident. 
Winter  tires 
W inte r ti res s ignificantly  improve  the  vehicle's 
h andling  when  driving  in win ter condit ions . Be
cause of  the ir constr uction  (width,  compound, 
tread  pattern),  summer  tires  provide  less trac
tion  on  ice and snow . 
"'U se winter  t ires on  all  fo ur wheels . 
..  Only  use winter  t ires that  are approve d for  your 
v ehicl e. 
"' Please  note  that  the  maximum  permitted 
speed  may  be lower  with  winter  tires¢.&_ . An 
authorized  Aud i dealer  or au thori zed Aud i Serv
ice Fac ility  can  inform  you about  the  maximum 
permitted  speed fo r your  tires . 
"' Check  the  tire  press ure after  installing  wheels 
¢page  240. 
The effectiveness  of  winter  tires is reduced  great
l y when  the  tread  is worn  down  to  a depth  of 
0 .1 57 inch  (4  mm).  The  character ist ics of  winter 
tires  a lso de crease great ly as the  tire  ages, re
ga rdless of  the remain ing tread. 
WARNING 
- Never drive  faster  than  the  maxim um  per 
mitted  speed for  your  t ires. This cou ld cause 
the  tires  to  heat  up too  much.  Th is increases 
Wh eel s 
the  risk  of  an accident  because it  can cause 
the  t ire to  burst. 
- Always adapt  your  driving  to  the  road  and 
traffic  cond itions . Drive carefully  and  reduce 
your  speed on  icy or  slippery  roads . Even 
winter  t ires can  lose tract io n  on  black  ice. 
@ For the  sake of  the  environment 
Reinsta ll summer  tires  at the  app ropr iate 
time,  beca use they  prov ide  better  handling 
when  roads  are free  of  snow  and ice. Summer 
tires  cause less road  no ise, tire  wear  and fue l 
consumpt io n. 
(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,  on ly 
winter  tires  w ith  the

Snow  chains
