In stop-and-go  traffic,  adaptive  cruise  control  can 
brake  until  the  vehicle  is stationary  and  then  be
gin  driving  again  under  certain  conditions 
¢page  92. 
Audi  braking  guard  can  warn you  about  an  im
pending  collision  and  initiate braking  maneuvers 
¢page 94. 
Which  functions  can  be  controlled? 
When  you  switch  adaptive  cruise  control  on,  you 
can  set  the  current  speed  as  the  "control speed" 
¢ page  91,  Switching  on/off. 
When  driving,  you  can  stop  cruise  control 
¢ 
page  92 or  change  the  speed ¢ page  92 at 
anytime. 
You can  also  set the  distance  to  the  object  mov
ing  ahead  and  set  the  driving  mode  of the  adap
tive  cruise  control¢

General  information 
Applies to: veh icles  with  Audi adaptive  cruise  control 
Fig.  91 Front  of t he  vehicle:  sen sors and  video  came ra 
The areas  that contain the  radar  and  ultrasonic 
sensors  and  the  video  camera¢ 
fig.  91 must  not 
be  covered  by stickers,  deposits  or  other  objects 
because  they can interfe re with  the  function  of 
the  adaptive  cruise  control  system  and  braking 
guard.  For  information  on cleaning,  refer  to 
¢ 
page  235. The  same  applies for  any modifica
tions  made  in the  front  area. 
The function  of the  adaptive  cruise  control  sys
tem  and  brak ing  guard  is  limited under  some 
conditions. 
- Objects  can  only  be  detected  when  they  are 
within  the  sensor  range¢ 
page  88 , fig.  90 . 
Assist 
- The  system  has  a  limited  ability  to  detect  ob
jects  that  are  a  short  distance  ahead,  off  to  the 
side  of your  vehicle  or  moving  into your  lane. 
- Objects  th at  are  difficult  to detect  such  as  mo
torcycles,  vehicles  with  high  ground  clearance 
or  an  overhanging  load are detected  late  or not 
detected  at  all. 
- When  driving  through  curves 
¢page  90. 
-With  stationary  objects ¢ page  90. 
A WARNING ~ 
Always  pay  attention  to  traffic  when  adaptive 
cruise  control  is switched  on  and  braking 
guard is active.  As the  driver,  you  are still  re
sponsible  for starting  and  for maintaining 
speed  and  distance  to  other  objects.  Braking 
guard  is  used to  assist  you . The  driver  must 
always  take  action  to  avoid  a  collision. The 
driver  is always  responsible  for  braking  at the 
correct  time. 
- For  safety  reasons,  do  not  use  adaptive 
cruise  control  when  driving  on  roads with 
many  curves,  when  the road  surface  is in 
poor  condition  and/or  in bad  weather  (such 
as  ice, fog,  gravel,  heavy  rain  and  hydroplan ing).  Using  the  system  under  these  condi
tions  increases  the  risk of  an  accident. 
- Switch  adaptive  cruise  control  off  tempora
rily  when  driving  in turning  lanes,  on  ex
pressway  exits  or  in construction  zones. This 
prevents  the  vehicle  from  accelerating  to 
the  stored  speed  when  in these  situations. 
- The  adaptive  cruise  control  system will  not 
brake  by itself  if you  put  your  foot  on  the  ac 
celerator  pedal.  Doing  so  can  override  the 
speed  and  distance regulation. 
- When  approaching  stationary  objects  such  as  stopped  traffic,  adaptive  cruise  control 
will  not  respond  and  braking  guard  will  have 
limited  function. 
- The  adaptive  cruise  control  system  and 
braking  guard  do  not  react  to people,  ani
mals,  objects  crossing  the  road  or  oncoming 
objects. 
- The  function  of  the  radar sensors  can  be  af
fected  by reflective  objects  such  as  guard  rails,  the entrance  to  a tunnel,  heavy  rain  or 
ice.

_&. WARNING 
- Improper  use  of  adaptive  cruise  control  can 
cause  collis ions,  other  accidents  and  serious 
personal  injury . 
- Never  let  the  comfort  and  convenience  that 
adaptive  cruise  control  and  braking  guard 
offer  d istract  you from  the  need  to  be  alert 
to  traff ic conditions  and  the  need  to  rema in 
in full  control  of your  vehicle  at  all  times, 
- Always  remember  that  the  adaptive  cruise 
contro l and  braking  guard  have  limits  - they 
will  not  slow  the  veh icle  down  or  ma intain 
the  set  distan ce when  you  drive  towards  a n 
obstacle  or something  on  or  near  the  road 
that  is  not  moving,  such  as  vehicles  stopped  in a  traffic  jam,  a stalled  or  disabled  vehicle . 
If  registered  by the  radar  sensors,  vehicles 
or obstacles  that  are  not  moving  can  trigger 
a collision  warn ing  and  if confirmed  by the 
video  camera,  a n acute  collision  warning . 
- Never  follow  a veh icle  so  closely  that  you 
cannot  stop  your  vehicle  safe ly . The  adap 
t ive cr uise  control  cannot  slow  or  brake  the 
vehicle  safely  when  you  fo llow  another  veh i
cl e  too  close ly. Always  remember  that  the 
automa tic braking  func tion  cannot  br ing  the 
vehicle  to  a  sudden  or  emergency  stop  un
der  these  condit ions . 
- T o  prevent  unintended  operation,  always 
switch  ACC off  when  it  is not  being  used . 
(U) Note 
The  sensors  can  be  displaced  by impacts  or 
damage  to  the  bumpe r, whee l housing  and 
underbody.  That  cou ld  affect  t he adaptive 
cruise  control  system  and  braking  guard . 
Have an  authorized  Audi dealer  or  authorized 
Audi Serv ice  Facility check  their  function.

The  adaptive  cru ise  control  system  only  reacts  to 
objects  that  are  moving  or t hat  the  system  has 
already  detected  as  moving . For example,  it  can 
react  when  a vehicle  that  has  already  been  de
tected @ turns  or  changes  lanes,  but  adaptive 
cruise  control  does  not  react  to  a  stationary  veh i
cle @.

Audi  braking  guard 
Applies  to:  ve hicles  w ith  Audi adaptive  cruise  co ntro l 
Fig . 100 In str um ent  clus te r:  appro ach  warning 
The  braking  guard  uses  radar  sensors  and  a video 
camera . 
It also  functions  within  the  limits  of the 
l) This is  no t  a vail able  in  som e  coun trie s. 
94 
system  when  adaptive  cru ise  control  is switched 
off. 
What  can the  braking  guard  do ? 
When  detected  in time, the  system  can  assess 
dange rous  si tu at ions  where  an object  ahead 
brakes  sudden ly or  if yo ur own  vehicle  is  trave ling 
at  a  h igh  speed  and  approach ing  an  ob ject  that  is 
moving  more  slow ly. The  braking  guard  does  not 
react  if it  cannot  detect  the  situation. 
The  system  advises  you  of var ious  dange rous  sit
uations : 
- The 
di stan ce warning occu rs  if you  dr ive too 
close ly  to  the  object  ahead  fo r a  long  per iod  of 
time . 
If the  object  ahead  brakes  strongly,  you 
would  not  be  ab le  to  avoid  a  co llis ion.  The . 
indicator  light  appears  as  an  indication  for  this . 
- T he 
appr oach w arning occurs  when  an  object 
ahead  is trave ling  more  slowly  or  brakes 
strongly.  When  this  warning  occurs,  it  may  only 
be  possible  to  avoid  a  collis ion  by swerving  or 
brak ing  strongly . The  danger  is  indicated  by the 
•  indicator  light 
¢fig. 100 . An audio  signal 
w ill also  so und . 
If  you  do  not  react  early  enough  or  at  all  to  a  dan 
gerous  situation,  the  braking  guard  supports  you 
with  a  braking  intervention . 
- If  a  co llision  is  imminent,  the  system  wi ll first 
provide  an 
acute warning by braking  sharply . 
- If you  do  not  react  to  th e acute  warning,  the 
b raking  guard  can  inc rease  the  braking  force 
w ith in the  lim its  of  the  system 
1> . This  reduces 
the  vehicle  speed  in the  event  of a  coll is ion. 
- T he  system  can  in itiate  complete  dece leration 
shortly  before  a  collision 
l) . Full deceleration  at 
high  speeds  occurs  only  in veh icles  with  adap
tive  cruise  control  and  side  assist  (pre  se nse 
plus) . 
- If the  braking  guard  determ ines  that  you  are 
not  braking  s trongly  enough  when  the re  is a n 
impending  coll is ion,  it can  increas e the  b raking 
force. 
- The  p re  sense  funct io ns also  engage  w hen

c::, page  95 , Settings  in  the Info
tainment  system. 
A WARNING 
Lack of  attention  can  cause  collisions,  other 
accidents  and  serious  personal  injuries.  The 
braking  guard  is an  assist  system  and  cannot 
prevent  a  collision  by itself.  The  driver  must 
always  intervene . The  driver  is always  respon
sible  for  braking  at  the  correct  time. 
- Always  pay  close  attention  to traffic , even 
when  the  braking  guard  is switched  on . Be 
ready  to  intervene  and  be  ready  to  take 
complete  control  whenever  necessary.  Al
ways  keep  the  safe  and  legal distance  be
tween  your  vehicle  and  vehicles  up ahead. 
- Braking  guard  works  within  limits  and  will 
not  respond  outside  the system  limits,  for 
example  when  approaching  a stopped  vehi
cle  or  stationary  obstacle  (end  of  a  traffic 
jam  or vehicle that  has broken  down  in traf
fic). 
- Always  remember  that  the  radar  sensor  for 
the  braking  guard  works  only  within  defined 
detection  and  range  limits  that  may  prevent 
the  proper  detection  of  other  vehicles . 
- The  radar  sensor's  function  and  range  can 
be  reduced  by rain,  snow  and  heavy  spray. 
Moving vehicles  up  ahead  may  not  be 
promptly  detected  or  may  not  be  detected 
at  all. 
- Reflective  surfaces  including  crash  barriers 
or  tunnel  entrances  may  impair  the  function 
of  the  radar  sensor. 
{!) Tips 
- You can  cancel  the  braking  with  increasing 
force  that  is  initiated by the  system  by brak
ing  yourself,  by accelerating  noticeably  or 
by  swerving. 
- Keep  in  mind  that  braking  guard  can  brake 
unexpectedly.  Always  secure  any  cargo or 
objects  that  you  are  transporting  to  reduce 
the  risk  of  damage  or  injury .

Description 
Appl ies  to:  vehicles with  Audi act ive  lane  assist 
Active  lane  assist  detects  lane  marker  lines  with
i n the  lim its  of  the  system  using  a camera  in the 
windshield.  If you  are  approach ing  a  detected 
lane  marker  line  and  it  appears  like ly that  you 
will  leave  the  lane,  the  system  w ill warn  you  with 
corrective  steering.  You can  override  this  steering 
at  any  time.  If you  pass  over  a  line,  the  steering 
whee l w ill  vibrate  lightly.  In  orde r fo r thi s warn
i ng  vibration  to occ ur, it  must  first  be  switched 
on  in  the  Infotainment  system.  Active  lane  ass ist 
is  ready  for  operation  when  the  lane  marker  line 
is detected  on  at  least  one  side  of  the  vehicle. 
The  system  is des igned  for  driving  on  express
ways  and  highways  and  therefore  on ly activates 
at  speeds  above  approximately  40  mph  (65  km/ 
h) . 
Applies  to:  vehicles with  side assist 
If you  activate  a turn  s ignal  when  act ive  lane  as
s ist  is  ready  and  it classifies  a  lane  change  as  crit 
ica l because  of  vehicles  traveling  a longside  you  or 
approach ing you,  there  wi ll be  noticeable  correc
tive  steer ing  shortly  before  you  leave  the  lane. 
This will  attempt  to  keep  your  veh icle  in the  lane. 
Applies  to:  vehicles without  side  assist 
The  system  will  not  wa rn you  befo re  c ross ing  a 
l ane  marke r line  if you  have  act ivated  the  t urn 
s ignal.  In this  case,  it  assumes  that  you  are 
changing  lanes  intentionally. 
Applies  to: vehicles with  adaptive  cru ise control

he lps  prevent  the  vehicle  from  driving  too  close 
to  them.  There  is also  passing  assistance . The 
system  does  not  provide  any  corrective  steering  if 
i t  detects  that  you  are  passing  another  veh icle .

is leav ing  the  lane  using  co rre ctive  s teer ing. 
T he  driver  is always  respo nsible  for  kee ping 
the  vehicle  within  the  lane .

t ive steering  can  o nly take  p lace  on  the  side 
of the  veh icle  where  lane  marker  lines  are 
detected. 
- Other  road  structures  or  objects  could  possi
bly be  identified  unintentiona lly as  lane 
marker  lines . As a  result,  corrective  steering 
may  be  unexpected  or  may  not  occur. 
- The  camera  view can  be  restricted,  for  ex ample  by vehicles  driv ing  ahead  or  by rain, 
snow,  heavy spray  or  light  shining  into  the 
camera . This can  result  in act ive  lane  assist 
not  detec ting the  lane  marke r lines  or  de
tecting  them  incor rectly. 
- Under  certa in conditions  suc h as  rut s  in the 
road,  a  bank ed  roadway  o r crosswinds , the
