brake and take  evasive action  to  avoid 
collisions  and  other  accident  situations. 
- Never allow  the  closing  speed between 
you and other  vehicles to  be so high  that 
the  adaptive  cruise control  may not  be 
able to  slow  your  vehicle  safely.  If  clos
ing  speed is too  high,  you  must  apply the 
brakes yourself  to  reduce the  risk of  a 
rear-end  crash . 
- Never rest your  foot  on the  accelerator  peda l, especia lly when  the  adaptive 
cruise control  is be ing used. Pressu re on 
the  accelerator  w ill override  the  ACC 
braking  function  and prevent  the  brakes 
from  being  applied  when  ACC detects  a  situation  when  the  brakes must  be ap
plied. 
- Never use adaptive  cruise contro l when 
you cannot  drive  safe ly at  a steady 
speed, including  on city streets,  on wind
ing  roads or  when  road  conditions  are 
poor  (for  example,  on  ice, gravel,  in fog, 
heavy rain  or  on wet  roads that  increase 
the  risk of  hydroplaning) . 
- The radar sensor 's 
vision can be reduced 
by rain,  snow and heavy road spray . 
T hese and sim ilar  condit ions can prevent 
vehicles  up a head from  being  accurately 
detected  and  in some cases they  may not 
be detected  at  al l.  Do not  use ACC when 
the  radar sensors cannot  accurately  de
tect  vehicles  moving  ahead of yo u in traf
fic . 
- Always turn  off  adaptive  cruise contro l 
when  entering  turn  lanes , exit  lanes and 
construction  zones or  in similar  situa
t ions because the  vehicle  will  automati
cally  accelerate  to  the  stored  speed when 
the  road ahead is clear. 
- To prevent  unintended  operation,  always 
switch  ACC off  when  it  is not  be ing used . 
(D Tips 
-For safety  reasons, the  stored  speed is 
deleted  when  the  ignition  is turned  off . 
- The E lectronic  Stab ilizat ion Control  (ESC) 
i s automatically  turned  on when the 
adaptive  cruise control  is turned  on. You  cannot  switch  the  ESC into  offroad  mode 
w hile  the  adaptive  cruise contro l is

-Damage caused by accidents  and  some 
mino r collisions  can affect  the  radar sen
sor settings  and cause the  system  to 
malf unction  or  switch  off  completely. 
- The radar sensor cover is heated.  In  win 
ter  conditions,  you should  st ill  check be
fore  dr iv ing to  make sure  it  is free  of  ice 
and snow. If  necessary, clean the  area 
near the  radar  sensor carefully 
<=>  fig . 126 . 
-To ensure that  the  radar sensor  is not 
blocked,  foreign  objects  (e.g . stickers, 
larger  license plate  mounts,  add-on 
parts)  mus t not  cove r the  area near the

How  does adaptive  cruise control  work? 
Applies to  vehicles:  wi th adap tive c ruise contro l 
Vehicles  traveling  ahead  are  detected  with 
the  aid  of  a  radar  sensor. 
F ig.  127  Basic p rin ci pl e diag ram:  Rada r se nso r me as
urement  ra n ge 
Adaptive  cruise  cont ro l uses a radar  senso r in 
the  front  o f the  vehicle<=> 
fig.  12 7.  The sys tem 
has  limitations <=> 
page  125 . Things that  are 
not  moving  in your  lane and in your  direction 
of  t rave l will  not  be detected.  The sensor 
measures the  distance  to  reflect ive surfaces 
tha t must  have  a ce rt a in s ize. The system  re
spond s on ly after  the  distance  measurement  ..,.  
Page 117 of 340

has  been  made.  If  a  measurement  is  not  pos 
sib le,  the  system  cannot  respond  and  wi ll not 
react  to  a vehicle  or  someth ing  else  up  ahead . 
Open  road 
When  the  road  is  clear , the  adaptive  cru ise 
control  wo rks  like cruise  control. 
It maintains 
a  constant  target  speed  specified  by the  driv
er. 
Driving  in traff ic 
If  a slower  vehicle  d riving  ahead  is  detected, 
the  adaptive  cru ise  contro l decelerates  (wi thin

to  its  speed  and  after  adjusting, 
tr ies  to  maintain  the  set  distance  from  the  ve
h icle  ahead.  The  vehicle  may  temporarily  drive 
slower  than  the  set  speed  while  adjusting 
¢ .&. in  Description  on page  113 . 
If  the  vehicle  in front  accelerates,  adaptive 
cru ise  control  also  accelerates  up  to  the  speed 
t ha t you  have  set. 
I f the  vehicle  ahead  slows  to  a  stop , ACC will 
slow  yo ur vehicle  down  and  to  a  complete 
s top  if this  is  possible  w ith in the  system's  lim
its  and  capabilities.  ACC will  not  make  an 
emergency  stop . The  text  message 
ACC off: 
manual  control!  appears  in the instrument 
cluster  display.  Once  the  veh icle  stops,  you 
must  dep ress  the  brake  pedal  to  prevent  the 
veh icle from  mov ing  forward  or  "creeping" . 
Depressing  the  brake  pedal  turns 
off ACC. 
When  the  vehicle  ahead  accelerates  yo u can 
reactivate  ACC 
¢ page  118, as  soon  as  your 
vehicle  has  reached  a  speed  of  1 mph  (2  km/ 
h) . 
Situat ion s requiring  dri ver  int ervention 
In  some  situations  you  wi ll have  to  use  the 
footbrake  to  s low  the  vehicle  down  in  order  to 
k eep  a safe  distance  from  vehicle  in front  of 
you  or  to  avo id  a  rear -end  coll is ion.  In  this  sit
uation,  a symbol  appears  and  a warning  tone 
sounds  ¢

Adapti ve  crui se control  115 
Passing another  vehicle 
If you  move  into the  passing  lane  and  no  ve hi
cle  is detected  ahead , the  adapt ive cr uise  con
trol  acce le rates  to  the  speed  you  have  set  and 
maintains  it. 
Overr iding  ACC 
You can  in cr ease  yo ur speed  at  a ny time  by 
stepping  on  the  accelera tor  ped al. A fter  you 
release  the  accelerator  peda l,  the  system  ad
justs  back  down  to  the  speed  you  prev ious ly 
set . 
Reducing  stopp ing distance 
If  the  radar  sensor  detects  that  the  d istance 
to  the  vehicle  a head  is less  than  de fined  m ini
mum  distance,  the  brakes  are  automatically 
prepared  fo r emergency  braking  by the  d river . 
The  brake  pads  are  moved  very  close  to  the  brake  d iscs  without  actually  braking  the  vehi
cle.  This  brake  assistant  feature  reacts  more 
quick ly to  the  dr ive r's  brak ing,  and  also  works 
when  adapt ive cruise  control  is 
off . The  stop
ping  distance  is  reduced  as  a  result  of  th is  ad
vance  brake  p reparation . Th is fun ction  does 
not  perform  any  emergency  b rak ing  mane u
vers  by  itse lf;  the  dr iver  mus t always  apply  the 
brakes. 
A WARNING 
If  ACC initiates  a  braking  maneuver,  the  brake  pedal  w ill be  retracted.  Inter ference 
with  the  brake  peda l can  prevent  ACC from 
slowing  the  veh icle  down  and  cause  a 
crash  and  serious  personal  injury. 
- Never  put  anything  in the  driver's  foot
well  or  let  anyth ing  fall  into  it.  An object 
in the  driver's  footwe ll can  inte rfe re  with 
the  peda ls  and  prevent  the  acce le rator 
from  being  used  to  override  ACC or  pre
vent  ACC from  being  switched 
off when 
the  brake  pedal  is depressed  and  also 
prevent  the  vehicle  from  being  slowed 
down  or  stopped . 
- Onl y use  floor  mats  that  keep  the  area 
aroun d the  peda ls free  and  that  can  be 
securely  fastened  to  the  footwell .

To decide  whether  it  is necessary  to  switch 
off 
the  ACC (ACC : Sensor  blocked)  or  if it  is only  a

System  limitations 
General  information 
Applies  to vehicles:  with  adaptive  cruise  co ntrol 
The radar  sensor has  limits  that  the  driver 
must  know  to  be able  to  use ACC properly . 
The adaptive  cruise control  works  within  lim its  that  are also related  to  radar  sensor range 
and sight  distance . In  some situations  ACC 
may react  unusually  or  late  from  the  driver's 
point  of  v iew. Therefore,  always be attent ive 
to  what  is happening  around  you  and always 
be ready to  intervene,  if  necessary: 
-when  driving  around  curves  ¢page  125 
- when  vehicles up front  are not  in  line  with 
your  vehicle ¢ page  126 
- when  other  veh icles are changing  lanes

A WARNING 
The radar sensor's function  and range can 
be reduced by rain,  snow and heavy spray. 
Moving  veh icles up ahead may not  be 
prompt ly detec ted or  may not  be detected

Audi  braking  guard 
Description 
Applies  to  vehicles: with  a daptive  cruise co ntrol 
Audi braking  guard  warns you  of  a possible 
collision  with a moving  vehicle  up ahead . 
Fig. 146 Display in the  instrument  cluster 
The Audi braking guard  is  active from  a  speed 
of  approx.  20  mph (30  km/h)  and works with
in the  system  limits¢ 
page 125 even when 
the  adaptive  cruise  contro l is  deactivated. 
A radar  sensor  is bu ilt  into  the  front  of  the  ve
hicle 
¢page  114, fig. 127. The system  is  in
tended  to  measure the distance  to  reflective 
surfaces . 
If a measurement  is not  possible, 
the  system  does not  respond. 
When  the  measurement  has  been taken,  the 
system  can recognize  a  possibly hazardous sit 
uation,  for example,  whe n a vehicle  up ahead 
in  your  lane  of  trave l sudden ly brakes or  when 
your  own vehicle  is moving  at  high speed to
wards  a much  slower  vehicle  up ahead . As 
soon as the  system  senses that  a possible  col
lision  with  the  vehicle  up  ahead can only  be 
avoided  by immed iate full  brake application  or 
by  an  avoidance maneuver,  a warning  appears. 
The system  has a defau lt  response  time  to  be 
able  to  signal  before  a collision  occurs. This 
system  response  time is automat ica lly re
duced  if you acce lerate  actively,  fo r example 
to join  a  highway. Braking,  transverse  acceler
ation  and the  steering  angle  can lead to  a re
duced  system  response time.  The warning  is 
deactivated  if  you begin to  overtake  with  full 
acceleration . 
Adaptive  cruise  control  127 
The system  can make you aware  o f two  differ
ent  hazardous  situations: 
Distance 
The distance  warning  is given  if  the  system 
calculates  that  there  is not  enough  distance 
to  the  vehicle  up  ahead a period of  more  than 
S seconds . If the  distance  is  less  than  30  feet 
(9  meters)  at  SO mph  (80  km/h),  for  examp le, 
an optical  display  comes  on  in the  instrument 
cluster¢ 
fig.  146. 
If  the  vehicle  ahead brakes sharp ly, Audi  brak
ing  guard  cannot  help you to  avoid a collision, 
even in the  case of  an  immediate  response. 
Take immed iate  action  to  avoid  the  co llision 
and  increase  the distance  to  the  vehicle  up 
ahead. 
Speed 
If  there  is a much  slower  vehicle  moving  up 
ahead in your  lane,  or  if  the  vehicle  ahead 
brakes sharply,  the  Aud i brak ing guard  calcu
lates  the  po int  from  which  a collision  can  only 
be avoided  by full  braking  or by an avoidance 
maneuver.  If  a warning  does sound,  a poss ible 
collision  with  the  ve hicle in front  can on ly be 
avo ided  through  an  evasive  maneuver  or  by 
braking. 
The  warning  is given  in two stages : 
-Pre-warning: A visual  display  appears  in the 
instrument  cluster  and a warning  tone 
sounds. 
- Acute  warning: If  you do  not  respond  to  the 
pre-warn ing, the  second stage  warning  is 
given.  A quick  brake application  helps  to  di
rect your  attention  to  the road and traffic 
situation.

Homelink 
Universal  remote 
control 
Description 
Applies  to  vehicles:  with  Home link 
The HomeLink  universal  remote  control can 
be programmed  with  the  remote  control for 
devices  that  are  already  present. 
With  Home Link, you  can  control  devices  such 
as  the  garage  door,  security  systems,  house 
lights , etc.  comfortably  from the  inside  of you 
vehicle. 
Homelink  makes it possible  for  you  to  rep lace 
three  different  remote  controls  from  devices 
in  your  home  with  one  universal  remote.  This 
feature  works  for  most  garage  door and  exte
rior door  motor  signals.  Programming  the  in
dividual  remote  control  for  your  remote  con 
trol  takes  place  on  the  left  side  of the  front  bumper.  There  is a control  module  attached  at 
this  location . 
A one-time  programming  of  the  sensor  must  be  performed  before  you  are  able  to  use sys
tems  with  Homelink.  If the  system  does  not  activate  after  performing  the  one-time  pro
gramming,  check  whether  the  system  uses  a rolling  code 
¢ page  163 . 
A WARNING 
-Never  use  the  Homelink transmitter 
with  any  garage  door  opener  that  does 
have  not  the safety  stop  and reverse  fea
ture  as  required  by federa l safety  stand
ards.  This  includes  any  garage  door  open
er  model  manufactured  before  April 1, 
1982. 
- A garage  door  opener  which  cannot  de
tect  an  object,  signaling  the  door  to  stop 
and  reverse  does  not  meet  current  feder
al safety  standards . Using  a  garage  door 
opener  without  these  features  increases 
risk of  serious  injury or  death. 
Homelink  161

- A garage  door  or  an  estate  gate  may 
sometimes  be  set  in motion  when  the 
Homelink  remote  control  is being  pro
grammed.  If  the device  is repeatedly  ac
tivated,  th is can  overstrain  motor  and 
damage  its  electrical  components - an 
overheated  mo to r i s  a fire  hazard! 
- To avoid  possib le  injuries  or  property 
damage,  please  always  make  abso lutely 
certa in that  no persons  or  objects  are  lo
cated  in the  range  of  motion  of  any
