Speed  warning  system 
Introduction 
The speed  warning system  helps you  to stay  un
der a specified  maximum  speed . 
The  speed  warning  system  warns  you  if you  are 
exceeding  the  maximum  speed  that  you  have  set . 
You w ill hear  a warning  tone  when  your  speed  ex 
ceeds  the  sto red  val ue  by app rox imately  3  mph 
(3  km/h) . An indicator  light . (USA mode ls)/ .

below  the  stored  maximum  speed. 
Set ting  a t hreshol d  is  recom mended  if you  would 
lik e to  be  rem inded  when  you  re ach  a  cert ain 
maximum  speed . Si tua tions  where  you  may  want 
to  do  so  include  drivin g in  a  country  w ith  a  gene r
a l speed  limit  or  if there  is a  specified  max imum 
speed  for  winter  tires. 
(D Tips 
Eve n though  your  vehicle  is eq uipped  w ith  a 
speed  warning  system,  you  should  still  watch 
the  speedometer  to  make  sure  yo u are  not 
drivi ng faster  than  the  speed  lim it.

winding  roads  and  when  road  cond itions  are 
poor  (such  as  ice, fog,  gravel,  heavy  rain  and 
hydroplaning),  because  this  increases  the 
risk of  an  accident. 
- Switch  the  cruise  control  off  temporarily 
when  dr iv ing  in turning  lanes,  h ighway  ex its 
or  in  construction  zones. 
- Please  note  that  unconsciously  "resting"  your  foot  on  the  accele rator  pedal  p revents 
the  cruise  control  from  braki ng.  This  is d ue 
to  the  contro l system  being  over ridden  by 
the  dr iver's  acceler ation. 
- I f a  brake  system  malfunction  such  as  over
hea ting  occurs  when  the  cruise  cont ro l sys

Audi  adaptive  cruise 
control  and  braking 
guard 
Introduction 
App lies  to  vehicles:  with  Audi adaptive  cruise  control 
The  adaptive  cruise  control  system assists  the 
driver  by regu lating  vehi cle  speed  and  helping  to 
maintain  a set  distance  to  the  vehicle  ahead, 
within  the  limits of the  system. 
If the  system  de
tects  a  moving  vehicle  up  ahead, adaptive  cruise 
control  can  brake  and  then  accelerate  your  vehi
cle.  This  helps  to make  driving  more  comfortable 
both  on  long  highway  stretches  and  in stop-and
go  traffic. 
The  braking  guard  system  can  warn  you  about  an  impending  collision  and  initiate  braking  maneu
vers¢ 
page 91. 
Adaptive  cruise  control  and  braking  guard  have 
technica l limitations  that you  m ust  know,  so 
p lease  read  this  section  carefu lly, understand 
how  the  system  works and  use  them  properly at 
all  times.

page 205. The  same  applies  for  any 
modif ications  made  in the  front  area. 
T he  function  of  the  adaptive  cru ise  contro l sys
tem  and  braking  guard  is limited  unde r some 
conditions: 
- Objects  can  only  be  de tected  when  they  are 
w ith in sensor  range 
¢page 87, fig. 92. 
- The  system  has  a  limited  ability  to  detect  ob
jec ts that  are  a  shor t distance  ahead,  off  to  the 
side  of yo ur vehicle  or  mov ing into  your  lane . 
- Some  kinds  of veh icles  are  hard  to  detect;  for 
examp le  motorcycles,  vehicles  with  high 
ground  clear ance  or  overhanging  loads  may  be 
detected  when  it  is too  late  o r they  may  not  be

_& WARNING 
Always  pay  a ttent ion  to  traffic  when  adap tive 
cr uise  control  is switched  on  and  braking 
guard  is active.  As the  driver,  you  are  sti ll re
sponsib le  for  starting  and  for  maintaining 
speed  and  distance  to  other  objects.  Braking 
guard  is used  to  assist you.  The  driver  must 
a lways  take  action  to  avo id  a  col lision . The 
d river  is  always  responsible  for  brak ing  at  the 
correct  t ime. 
- Improper  use  of  adaptive  cruise  control  can  cause  collisions,  other  accidents  and  serious 
pe rsonal  inj ury. 
- Never  let  the  comfort  and  conve nience  that 
adapt ive cr uise  control  and  b rak ing  guard 
offer  distrac t you  from  the  need  to  be  alert 
to  traffic  condit io ns and  the  need  to  remain 
in  full  control  of your  veh icle  at  all  times, 
- Always  remember  tha t the  adaptive  cruise 
con trol  and  bra king  guard  have  limits  -they 
will  no t slow  the  vehicle  down  or  maintain 
the  set  distance  when  you  dr ive towards  an 
obstacle  or  something  on  or  near  the  road 
that  is  not  moving,  s uch  as  vehicles  stopped 
in  a traffic  jam,  a stalled  or  disabled  vehicle. 
If  registered  by  the radar  sensors,  vehicles 
or  obstacles  that  a re  not  moving  can  trigger 
a  collision  wa rning  and  if confirmed  by the 
video  came ra,  an  acute  collision  warning.

Audi adapt ive  cru ise  control  and  brak ing  gu ard 
- 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  hydrop lan
ing).  Using  the  system  under  these  condi
t ions  could  resu lt  in a  col lision. 
- Switch  adaptive  cruise  control  off  tempora
rily when  driving  in turn ing  lanes,  on  ex
pressway  exits  or  in construction  zones.  This 
prevents  the  vehicle  from  accelerating  to 
the  set  speed  when  in these  situat ions. 
- The  adapt ive cr uise  control  sys tem  wi ll not 
brake  by itself  if yo u put  you r foot  on  the  ac
celerator  pedal.  Doing  so  can  ove rride  the 
speed  and  distance  regulation. 
- When  approach ing  stationary  objects  such 
as  stopped  traffic,  adaptive  cruise  control 
will  not  respond  and  braking  g uard  will  have 
limited  function. 
- The  adapt ive cr uise  control  system  and  brak
ing  guard  do  not  react  to  people,  animals, 
objects  cross ing  the  road  or  oncoming  ob
jects . 
- 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. 
- Never  follow  a veh icle  so  closely  that  you 
cannot  stop  your  vehicle  safe ly . The  adap
t ive cru ise  control  cannot  s low  or  brake  the 
vehicle  safely  when  you  fo llow another  veh i
cl e  too  close ly. Always  remembe r that  the 
automa tic  brak ing funct ion  c annot  bring  the 
vehicle  to  a  sud den  or emergency  stop  un
der  these  conditions. 
- To  prevent  unin tended  operation,  always 
switch  ACC off  when  it  is  not  be ing  use d. 
(D Note 
The sensors  can  be  displac ed  by impacts  or 
damage  to  the  bum per,  whee l hou sing  and 
unde rbody.  That  could  affe ct  the  adap tive 
cruise  contro l system  and  braking  guard .  Have 
your  authorized  A udi dealer  or  authorized 
Audi Service  Facility  c heck their  function.

When  dr iving  into  a  curve c:::> fig. 90 and  out  of  a 
curve , the  adaptive  cruise  control  may  react  to  an 
object  in the  neighboring  lane  and  apply  the  brakes . You ca n prevent  that  by pressing  the  ac
ce lerator  pedal  b riefly.

The  adaptive  cruise  contro l system  only  reacts  to 
ob jects  that  are  moving  or  that  the  system  has 
already  detected  as  moving.  For example,  it  can 
react  when  a vehicle  that  has  already  been  de
t ec ted @  turns  or  changes  lanes,  but  adapt ive 
cruise  control  does  not  react  to  a stationary  vehi 
cle @.
