- Occasiona l noises when  the  parking 
brake is applied  and  re leased are norma l 
and are not  a cause for  concern. 
- When  the  vehicle  is parked,  the  parking 
brake goes through  a se lf-test  cycle at 
regular  intervals.  Any assoc iated  noises 
are norma l.

sure  that  you  a re develop ing  enough  dr iv ing 
f orce  at  the  wheels  by dep ress ing  the  accel
erator. 
Depending  on  the  weight  of  the  r ig  (veh icle 
and  tra iler)  and  the  seve rity of  the  in cli ne , you 
may  roll  backwards  as  you  start . You can  pre 
vent  rolling  backwards  by holding  the  parking  brake  switch @ pulled  out  and  accelerating  -
just  as  you  would  when  starting  on  a  hill  with 
a  conventional  hand  brake. 
Emergency braking 
In  the  event  that  the  conventional  brake  system 
foils or locks. 
...  In  an  emergency,  pull  the  switch @

Speed  warning  system 
Overview 
The speed  warning  system  helps you  to  keep 
your  driving speed  below  a set  speed  limit. 
T he  speed  warning  system  warns  if the  driver 
e xc eeds  a  previously  stored  max imum  speed . 
A warning  tone  w ill sound  as  soon  as  the  vehi 
cle  speed  exceeds  the  set  speed  by abou t 
3  mph  (3  km/h) . At the  same  t ime,  a warning 
symbol  appears  in the  display . T he  symbol's 
appea rance  might  be  different  in some  mod
els  . 
The  speed  warn ing  system  has  two  warning 
t hr esholds  that  funct io n  in dependent ly of 
each  other  and  that  have  somewhat  diffe rent 
purposes: 
Speed wa rning  1 
You can  use  speed  warning  1 to  se t the  maxi
mum  speed  while  you  are  driving . T his  setting 
will  remai n in effect  unt il you  turn  off  the  ig ni
t io n,  assuming  that  you  have  not  changed  or

T he  speed  warn ing  symbol  will  also  go  out  if 
the  speed 
exceeds the  stored  maximum  speed 
by more  than  about  25  mph  (40  km/h)  for  at 
least  10  seconds.  The  sto red  max imum  speed

A WARNING 
- Always pay attention  to  the  traffic 
around  you  when  the  cruise  control  is in 
operation.  You are  always  responsible  for 
your  speed  and  the  distance  between 
your  vehicle  and  other  vehicles.  -
For reasons  of safety , cruise  control 
should  not  be  used  in the  city,  in stop
and-go  traffic,  on  twisting  roads  and 
when  road  conditions  are  poor  (such  as  ice, fog,  gravel,  heavy  rain and  hydro
plan ing)  - risk of  accident. 
- Turn  off the  cruise  control  temporarily 
when  enter ing  turn  lanes, highway  exit 
lanes  or  in constr uction  zones  . 
- Please  note  that  inadve rtently  "resting" 
your  foot  on  the  accelerator  pedal  causes 
the  cruise  control  not  to  brake.  This is 
because  the  cruise  control  is overridden 
by  the  drive r's  acceleration. 
- If a  brake  system  malfunction such  as 
overheating  occurs  when  the cruise  con
trol  system  is switched  on,  the  braking 
function  in the  system  may  be  switched 
off . The  other  cruise  control  functions  re
main  active  as  long as  the  indicator  light 
[ff;(l)~i4 (US models) ;B (Canadian  mod

On slopes,  activate  the  parking  brake first  and 
then  move the  selector  lever to  the  P position. 
This prevents  too  much stress from  being  placed on the  locking  mechanism. 
Vehicles with  multitronic  transmission : Your 
vehicle  is equipped  with 
hill hold  assist allow
ing you to  start  while  on an incline.  The sys
tem  is activated  when  the  brake pedal is 
pressed down  and held 
for a  few seconds. The 
brake p ressure will  hold  for  a moment after 
the  brake pedal  loosens to  prevent  the  vehicle 
from  rolling  backwards while  starting  up. 
A WARNING 
-The vehicle  can also  roll  when  the  engine 
is stopped. 
- Unintended  vehicle  movement  can cause 
serious  injury. 
- Never leave your  vehicle with  the  engine 
running  while  in  gear.  If you  must  leave 
your  vehicle  when  the engine  is running, 
activate  the parking  brake  and move the 
selector  lever to  P. 
- Power is still  transmitted  to  the  wheels 
when  the engine  is running  at  idle.  To 
prevent  the vehicle from  "creeping",  you 
must  keep your  foot  on the  brake when 
the  engine  is running  and the  selector 
lever  is  in D/S or  R or  "tiptronic"  mode  is 
selected. 
- Do not  press the  accelerator  pedal when 
changing  the  selector  lever position 
while  the  vehicle  is stationary  and the 
engine  is running . 
- Never shift  into  R or  P while  driving. 
- Before driving  down  a steep  slope,  re-
duce your  speed and  shift  into  a lower 
gear with  "tiptronic". 
- Do not  ride the  brakes or  press the  brake 
pedal too  often  or too  long  when  driving 
down  a hill.  Constant  braking  causes the 
brakes to  overheat  and substantially  re 
duces braking  performance,  increases 
Transmission  89 
braking  distance  or  causes complete  fail
ure of  the  brake system. 
- To prevent  the  vehicle  from  rolling back 
when  stopping  on  inclines,  always  hold  it 
in place with  the  brake pedal  or  parking 
brake. 
- Never hold  the  vehicle  on an incline  with  a slipping  clutch.  The clutch  opens auto
matically  when  it  becomes too  hot  from 
the  overload . An  indicator  lamo 
[O] illu
minates  and a driver  message appears 
¢ page  92  when  the  clutch  is overload
ed. 
- If  the  engine  must  remain running,  never 
have any driving  position  engaged when 
checking  under  the  hood . Make sure the 
selector  lever has securely engaged  and 
is  locked  in  P with  the  parking  brake set 
¢ page  205,  Engine compartment.  Oth
erwise,  any increase in engine  speed may 
set the  vehicle  in  motion,  even with  the  parking  brake applied. 
(D Note 
- S tronic ®- and tiptronic  transmission: 
When  stopping  on an  incline, do not  try 
to  hold  the  vehicle  in  place by pressing 
the  accelerator  pedal while  a driving  gear 
is selected.  This can cause the  transmis 
sion to  overheat  and can damage  it. Acti
vate  the  parking  brake or  press the  brake 
pedal  to prevent  the  vehicle  from  rolling . 
- S tronic ®- and tiptronic  transmission:  Al
lowing  the  vehicle  to  roll  when  the  en

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  regulat 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  he lps to  make  driv
ing  more  comfortable  on  long highway 
stretches. 
The  braking  guard  system  can  warn  you  about 
an  impending  collision  and  initiate braking 
maneuvers¢ 
page 100. 
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  system  has  a  limited ability  to  detect 
objects  that  are  a  short  d istance  ahead,  off 
to  the  side  of your  vehicle  or  moving  into 
your  lane. 
- Some  kinds  of  vehicles  are  hard  to  detect; 
for  examp le  motorcycles,  vehicles  with  high 
ground  clearance  or  overhanging  loads  may 
be  detected  when  it  is  too  late  or  they  may

110  Park  assist 
Park  assist 
Parking  system 
Applies to vehicles:  with  pa rking system 
Different  park  assist systems  may  be used for 
parking  or  maneuvering,  depending  on the 
vehicle's  features. 
Parking  system  (rear)*: 
For the parking  system  (rear), the  acoustic 
park assist  system  is installed  in the  rear of 
the  vehicle 
¢ page  110. 
The rear  parking assist system  uses ultrason ic 
sensors  to  determine  the  distance  of  the  vehi
cle from  a  detected obstacle. There  are a total 
of  four  sensors located  on the  rear bumper 
(two  in the  middle  and two  on the  sides). 
Parking  system (rear, with rear  view 
camera)*: 
For the parking  system  (rear,  with  rear  view 
camera), 
the  rear  acoustic  park  assist  system 
is  integrated  in  the  rear  of the  vehicle  and the 
rear  view camera  is integrated  in the  rear  lid 
¢page  113. 
The parking  system  (rear,  with  rear  view cam
era) 
uses  ultrasonic  sensors to  determine  the 
distance  of  the  vehicle  from  a  detected obsta
cle . There  are a total  of  four sensors located 
on  the  rear bumper  (two  in the middle  and 
two  on  the sides). 
Parking  system  (rear) 
Rear acoustic park  assist 
App lies  to  vehicles:  with  parking system  (rear) 
The rear  acoustic  park assist  warns you  of  ob
stacles  or  objects  behind  your  car. 
Description 
The rear acoustic  parking ass ist system  deter
mines  the  distance  of  the  vehicle from  an ob
stacle  using  ultrasonic sensors. There  are 4 
sensors  in the  rear bumper. 
The range  at  which the senso rs start  to  meas
ure is 
about : 
To the  side  2 ft (0.60 m) 
Center  rear 5.2 ft  (1.60  m) 
Activation 
Acoustic  parking  assist  is  activated  automati
ca lly when 
reverse  gear is engaged.  A brief 
tone  confirms  that  the system  is activated. 
Warning  tones 
Distance  warning is given  by warn ing tones 
which  are generated  by the rear signal genera
tor.  The volume  and the  pitch  of the  warning 
tones  can  be adjusted  in the  MMI* 
¢page  111. 
Reversing 
Distance  warning when  reversing  starts when 
an  obstacle  is detected  in the  range  of the 
parking  assist  system . As the  distance  de
creases, the  time  interval between  the  audible 
tones  becomes  shorter. 
When  the  distance  is  less than  1ft  (0.30  m), 
the  tone  becomes  continuous.  At  this  point 
you should  stop  backing  up . 
Please note  that  low  objects already signalled 
by a  warning  can  disappear from  the  system's 
detection  range and will  not  continue  to  be 
signalled . 
If the distance  to  an obstacle  remains  the 
same,  the volume  of  the  distance  warning is 
gradua lly  reduced  after  about  4 seconds (this 
does  not apply  in the  continous  tone  range). 
Approaching  another  obstacle  will  resu lt  in 
the  distance  warning  sounding  at  the  normal 
volume  again. 
Malfunctions in the  system 
If  a warning  tone  is audible  for  about  five  sec
onds  when  you turn  on  the  ignition , there  is a 
malfunction  in the  system.  Have the  problem 
corrected  by your  authorized  Audi  dealer. 
Keep  the  sensors  in the  rear  bumper  clean  and 
free  from  ice so that  the  acoustic  park  assist 
system  can function  properly.
