Speed  warning  system 
Introduction 
The speed  warning  system  helps you  to  stay 
under  a specified  maximum  speed . 
The speed warning  system  warns  you  if  you 
are exceeding the  maximum  speed that  you 
have  set. You will  hear a warning  tone  when 
your  speed  exceeds the  stored  value  by ap
prox imately  3  mph  (3  km/h) . An  indicator 
light . (USA  models)/ . (Canada  models)  in 
the  instrument  cluster  display  also turns on at 
the  same time . The  indicator  light 
a;m 
turns  off when  the  speed decreases below  the 
stored  maximum  speed. 
Sett ing  a th resho ld  is  recommended  if you 
wou ld  like  to  be reminded  when  you reach a 
certain  maximum  speed.  Situations where  you 
may want  to  do  so  include  driving in a country 
with  a general  speed  limit or  if there  is a 
specified  maximum  speed for  winter  tires. 
(1} Tips 
Even though  your  vehicle  is equipped  with 
a speed warning  system,  you should  still 
watch  the  speedometer  to  make sure you  are not  driving faster  than  the  speed  limit. 
Setting  the  threshold 
You can set,  change  and  delete  the  threshold 
in  the 
MMI. 
.,..  Se lect: I CAR I function  button> (Car)*  sys

You can set  any threshold  between  20 mph 
(30  km/h)  and  lS0  mph  (240  km/h).  Settings 
can each be adjusted  in  increments of  6 mph 
(10  km/h).

Audi  adaptive  cruise 
control  and  braking 
guard 
Introduction 
App lies  to  vehicles:  with  Audi adaptive  cruise  co ntrol 
The  adaptive  cruise  control  system  assists  the 
driver  by regu lat ing  vehicle  speed  and  helping 
to  maintain  a set  distance  to  the  vehicle 
ahead,  within  the  limits  of the  system. 
If the 
system  detects  a  moving  vehicle  up ahead, 
adaptive  cruise  control  can  brake and  then  ac
celerate  your  vehicle.  This  helps  to  make  driv
ing  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 
maneuvers 
c:::> page 92. 
Adaptive  cruise  control  and  braking  guard 
have  technical  limitations  that you  must 
know,  so please  read  this  section  carefully,  un
derstand  how  the  system  works  and  use them 
properly  at  all  times.

The areas  that  conta in the  radar  and  ultrason

c:::> fig. 87 
must  neve r be  cove red  by stic kers  or  other  ob
jects  or  obstructed  w ith  dirt,  insects,  snow  or 
i ce that  will  interfere with  the  adaptive  cruise 
control  system  and  braking  guard.  For  infor
mation  on  cleaning,  refer  to 
c:::> page 213. The same  applies  for  any  modifications  made  in 
the  front  area. 
T he  function  of  the  adaptive  cru ise  contro l 
system  and  braking  guard  is limited  under 
some  cond itions: 
- Objects  can  only  be  de tected  when  they  are 
w ith in sensor  range 
c:::> page 88, fig. 90. 
- The  system  has  a  limited  ability  to  detect 
objects  that  are  a  short  d istance  ahead,  off 
to  the  side  of your  vehi cle  or  mov ing  into 
your  lane. 
- Some  kinds  of ve hicles  are  hard  to  detect; 
for  examp le  motorcycles,  veh icles  with  high 
ground  clearance  or  overhanging  loads  may 
be  detected  when  it is too  late  or  they  may 
not  be  detected  at all.

& WARNING 
A lways  pay  attention  to  traffic  when  adap 
tive  cruise  contro l is switched  on  and  brak
ing  g uard  is  active.  As the  dr iver, you  are 
still  respons ible  for  starting  and  for  main
taining  speed  and  distance  to  other  ob
jects.  Braking  guard  is  used  to  assist  you . 
The dr iver  must  a lways  take  action  to  avo id 
a  collis ion . The  driver  is a lways  respons ible 
fo r braking  a t the  co rrec t time. 
- Imp roper  use  of  adaptive  cru ise  control 
can  cause  collisions,  other  acc idents  and 
serious  pe rsonal  in jury. 
- Never  let  the  comfort  and  convenience 
that  adaptive  cruise  control  and  braking  gua rd offer  d istract  you  from  the  need  to 
be  alert  to  traffic  condit ions  and  the 
need  to  rema in  in fu ll control  of your  ve
h icle  at  a ll times, 
- Always remember  that  the  adaptive 
cruise  control  and  braking  guard  have 
limits  -they  will not  s low  the  vehicle 
down  or  maintain  the  set distance  when 
you  drive  towards  an obstacle  or  some
thing  on  or  near  the road  that is  not 
mov ing,  such  as  vehicles  stopped  in  a 
traffic  jam,  a stalled  o r disabled  vehicle.

vehicles  or  obstacles  that  are  not  moving 
can  trigger  a  collision  warning  and  if con
firmed  by the  video  camera,  an  acute  col lis ion  warn ing. 
- For safety  reasons,  do  not  use  adaptive 
cruise  control  when  driving  on  roads  with 
many  curves,  when  the  road  surface  is  in 
poor  condit ion  and/or  in bad  weather 
(such  as  ice,  fog,  gravel,  heavy  rain  and 
hydroplan ing).  Using the  system  under 
these  cond itions  cou ld  result  in a  co lli 
sion . 
- Switch  adaptive  c ruise  control  off  tempo
rar ily when  driv ing  in turning  lanes,  on 
expressway  exits  or  in construction 
zones . This  prevents  the  vehicle  from  ac
celerating  to  the  set  speed  when  in these 
situations . 
- The  adapt ive cru ise  control  system  w ill 
not  brake  by itse lf  if you  put  your  foot  on 
the  accelerator  pedal.  Doing  so  can  over ride  the  speed  and  distance  regulation . 
- When  approaching  stationary  objects  such  as  stopped  traffic,  adaptive  cruise 
control  will  not  respond  and  braking 
guard  w ill have  limited  function. 
- The  adapt ive cruise  control  system  and 
braking  guard  do  not  react  to  people , an
ima ls,  objects  crossing  the  road  o r on
coming  objects . 
- The function  of the  radar  sensors  can  be 
affected  by reflective  objects  such  as 
guard  ra ils,  the  entra nce  to  a tunnel, 
he avy rain  or  i ce. 
- Never  follow  a veh icle  so  closely  that  you 
cannot  stop  your  vehicle  safe ly. The 
adaptive  cruise  cont ro l c anno t slow  or 
brake  the  veh icle  safely  when  you  follow 
another  vehicle  too  closely.  Always  re
member  that  the  automatic  braking 
funct ion  cannot  bring  the  veh icle  to  a 
sudden  or  emergency  stop  under  these 
condit ions . 
- To  prevent  unintended  operation,  always 
switch  ACC off  when  it  is  not  be ing  used. (D Note 
The  sensors  can  be  displaced  by impacts  or 
damage  to  the  bumper,  wheel  housing  and 
underbody.  That  cou ld  affect  the  adaptive 
cruise  control  system  and  brak ing  guard . 
Have your  authorized  Aud i dea le r or  a u
thorized  Audi Serv ice  Facility check  their 
funct ion.

Description 
Applies  to vehicles:  with  Audi adaptive  cruise  control 
Fig. 90  Detection  range 
What can adaptive  cruise control  do? 
The  adaptive  cruise  control  system  uses  video, 
radar  and  ultrasou nd.  Moving  vehicles  ahead 
can  be  recognized  up  to  about  650  feet  (200  m)  away. 
On open  roads  w ith  no  traffic,  adaptive  cruise 
control  works  like a  regular  cruise  control  sys
tem.  The  stored  speed  is  maintained.  When 
approaching  a  moving  vehicle  detected  up 
ahead,  the  adaptive cruise  control  system  au
tomatically  s lows  down  to match  that vehi
cle's  speed  and  then  maintains  the  distance 
that  the  driver previous ly stored.  As soon  as 
the  system  does  not  detect  a vehicle  up 
ahead,  adaptive  cruise  control  accelerates 
back  up  to  the  stored  speed. 
In  stop-and-go  traffic,  adapt ive cru ise  control 
can  brake  until the  vehicle  stops  and  acceler
ate  again  under  certain  conditions  and  if this 
is possible  within  the  system's  limits and  ca
pabilities¢

will not  make  an  emergency  stop . 
Which  functions  can be controlled? 
When  you  switch  adaptive  cruise  contro l on, 
you  can  set  the  current  speed  as  the  "control  speed"  ¢ 
page  88,  Switching  on and  off. 
When driving,  you  can  stop  cruise  control 
¢ 
poge  90 or  change  the  speed  ¢ page  89 
at  any  time. 
You  can also  set  the  distance  to  the  object 
ahead  and  set  the  adaptive  cruise  control  driv
